content: Some people have said Dave is asking too much for a hobbyist/student employee to have basic design, layout, construction, debugging, and firmware skills.Naturally Dave thinks that's bullshit, and that is in fact the *definition* of a good hobbyist.Job description:http://www.eevblog.com/files/EEVblogJobDescription.pdf(Since modified to highlight I'm not after professional level skills, if that wasn't already obvious)

content: Certainly that's not too much to ask. On the other hand though, I have many friends who are 4th year EE students who I wouldn't trust with the probes of a multimeter if you told them where to put 'em. I also know many people with the skills you mentioned and would love such an opportunity whether it payed or not.

content: I would not have qualified in my youth as my boards were wirewrapped. I spent many nights experimenting trying to figure out how manufacturers got those solder traces to stick to a PCB. It never occurred to me that underneath there was copper was clad to the board and etched away. With the wealth of info available to kids these days, thanks to people like Dave, there really is no excuse for not having said skills except they are not "serious" hobbyists.

content: I think you're being reasonable. I am a professional software guy, but dabble in electronics hardware strictly as a hobby, with no intention of making money at it ever. I would meet your qualifications, except that I haven't made a PCB yet. All my projects have been one-off prototypes strictly for myself. I've built them using a variety of techniques, including at least one of virtually every kind of prototyping board, plus manhattan style and ugly construction.But you're right, PCB fabrication prices are getting cheaper. I should have a board made sometime soon.I'm not applying, because I'm on the wrong continent and I'm already employed.I guess if you don't get anyone who fully meets your requirements, you may have to relax things a bit, but I wouldn't go relaxing the requirements just yet...

content: I signed up to the EEVBlog forums to write this reply. I have been watching the blog videos for about 18 months now and really enjoy them but never felt the need to post in the forums.With "hobbyists" being useless, its not limited to hobbyists. I hold a cert. 3 in telecommunication electronics and I don't have have the skills you are asking for. I will admit that my current employment does NOT use any of the skills that I learnt as part of the cert 3. I am willing to admit that I would be more useless at these skill than some, if not most, hobbyists that watch your Vblog.But in having said that, I do design and make "BASIC" circuits at home in my spare time. Mostly things that I require or find interesting. I have never designed a PCB but rather just use protoboards.I would class myself as a hobbyist but i feel somewhat deflated after this video. I realize that this was not your intention (I hope)...Just my 2c worthRegards,Gibleh

content: In my own case. I was an EE student but switched to CompSci my SENIOR year. It was the mid 80's and I simply decided that I liked all the new exciting computer stuff more. I don't regret that decision, the 80s, 90s, and first decade of the 2000's were exciting times in IT and provided a very interesting career.So, while I am not an EE, I ended up an IT professional for the last 20 years, but it was my original interest, and it and ham radio have made it my hobby. I don't remember everything from school, and lots of it is not all that up to day anyway probably, but it certainly provided a very good 'base' for my hobby electronics experimentation. In my hobby level electronics I am pretty sure I would fit your skills myself and I have never worked a single day as an EE or with electronics professionally, its all been an IT career for me.For many people computer stuff is a hobby, for me at the skill level I have now, its almost too easy to do nearly anything IT related and it has become just a "job" that I don't want to do at home as well as work. So ham radio and electronics provide that same mental stimulation and challenge that computers used to provide me when I was young.I do believe your best bet to find someone that would fit WOULD be either a hobbyist or maybe a retired EE who used to be technical but at some point got into mgmt, sales, consulting etc, but still has a love of electronics and would enjoy doing it again.Frankly, I think you should have "Advanced Amateur Radio License" as a job requirement.If you want a group of non-EE professionals who have serious electronics skills, hang around ham radio people.

content: Dave, you're not asking too much. It is just that you're competing for a person who can be better paid and wouldn't want to work as a lab assistant. These skillsets are there, but you will need to compensate them accordingly. It is not a question about your requirements can be considered a basic skillset - it is the pressure of the market that will determine whether you will find someone or not.Hell, the reality is that (atleast in the US colleges) majority engineers who graduate with a Bachelors in EE do not have the "basic" skillset you have listed. This has been my experience in a IV league college in America. Not kidding.I truly hope you find someone who is passionate and willing to work for a lower wage and in a fun environment.Cheers and my two cents. I apologize if it was harsh.

content: I think all a person needs is a hunger for electronics. Dave listed a few things but a hobbyist can also work work a drill and make a case, label it and so on. 40 years ago it was a big deal to have a VOM, fixit shops repairing TV's and such where common place you cold call them hobbyists.Today there is so much more available, microcontrollers, parts that you can actually buy, datasheets to download. Instructions on how to program. Everything is there.If you hear of a new (neat) chip, board whatever, do you buy it and play with it? If the answer is yes you are a hobbyist in my book you are doing it for the sheer enjoyment.Dave is by definition looking for a person that enjoys electronics.

All you learn at university is how to sit exams, and theoretical concepts that the bad students can't connect to FR-4 (and time management, and ethics, actually useful things to be fair, but the ability to prepare a prototype? bahahaha). If I was in Dave's position, I would want the former, and that's exactly what he's going for, so

Yes the current stuff is amazing, and so much easier than before, but it is regarded as basic. There is little training and most are not interested, but those who are have a wealth of good education available for essentially the time that they devote to it.

content: I don't think anyone said that some "hobbyists" don't have the skills you listed. You missed the point.As a side note, I don't think you're going to find that skill set in a student. I can't speak for Universities in Australia, but in the States, it's common for a EE grad to have very little hands on experience. I see a whole lot of student's senior projects made with stuff cobbled together from Sparkfun - all hooked up with jumper wires.And if you do find a student, then perhaps they could do a summer internship, but a full course load and working up to 30 hours a week? That's slim pickings. But....Maybe if they are required to an internship as part of their studies, then that would work. But that's going to be even harder to find. Why don't you go to someone of the local universities and ask? Surely they would need to 'vet you before they can sign off on you being part of their education. They may even underwrite the whole thing. (Also, they usually have job boards you can post on) - that would be where I would start.Anyways, there some helpful suggestions for you.So that leaves you with an advanced "hobbyist". If you can find someone with the skill set you listed, doesn't need money, then more power to you I guess.(ya cheap bastard!)Maybe the job title should be "Wanted: Nerd that lives with his parents, doesn't smelltoomuch, won't take up my time, and willing to work for peanuts."

content: Dave,you have clearly defined the requirements, so it's absolutely not the question, whether these are correct, or not.These are simply your necessities for that person.I understand which skills you have in mind, because I started the same way, being a teen..At the age of maybe 12 I started soldering simple electronics, (after playing around with KOSMOS Radioman for years already), always had these yellow / brown fingers from etching with Fe3Cl, layouts at first directly rubbed on PCB, later on transparent foil and transferred to UV photo resist mask.. and learning each and every aspect of analogue and digital electronics on my own later on.This evolutionary learning was very common at that time, i.e. 40 years ago, but that faded away later, and maybe now is popular again, as can be observed here in this forum.Therefore I hope, that you will find such a (younger) person, who would also have to have a charitable attitude.Because if someone already has all these skills, nowadays the people also know, what it's worth.. and you did not even specify the hourly wage, you old CHEAPSKATE!Frank

content: I reckon some of the blame goes to use of tech language* and jargon.Dave's struggling at the best of times, but it's so easy to toss in phrases like PCB design, SMPS repair, and other 'umbrella' phrases - if you are so familiar with the repercussions and drill-dowen to the necessities of each.Specific skills may exist, but need to be tuned to a specific project requirements as the newbie learns you and where you've been.I admit the laundry list was pretty complete, but expecting a young/cheap person with all those skills reedy to go - able to apply them at a semi-pro level is a big ask.The advent of Chinese consumer electronics and the ever-diminishing school science streams have also shrunk the pool of techno-literate (or inclined) teens over the last ten years.I suspect Dave may need two 'less skilled' bods at 0.5T to reach all the corners. Or a late twenties full-time paid colleague to achieve all the ticks.I agree with everything Dave mentions in the video, but he's reflecting on ten years ago... imagine thews of us looking back 30-40 years!!!*Microsoft are particularly prolific at redefining tech terms into muddy ambiguous, vague references to their original meaning.

content: I'd be interested to know what the typical profile of a young electronics enthusiast actually is. I suspect it's changed out of all recognition since I was in that category myself.Wind the clock back to the late '80s, I was a geek, or nerd, before the world had really worked out what those categories were. I was at school, 8-bit computers were the rule, and a few 16 or 32 bit machines were around (if you could afford them, which I couldn't).By current standards, those machines were incredibly accessible when it came to programming them. They'd boot up straight into a BASIC interpreter; giving them commands to execute didn't require another computer and a debug cable, you'd just start typing. Some had assemblers built in as well, and I remember proudly stating on my university application that I was fluent in both 6502 and ARM code.Peer around at the back and there was inevitably some kind of expansion interface, with chip selects, address and data buses there for the attachment of whatever you could come up with - provided you could get hold of a schematic or data book, of course. Very few of my peers actually chose to build hardware (it cost precious pocket money, after all), but we all became reasonably accomplished programmers. The ability to bypass the OS and poke hardware registers directly was both a necessary skill and a badge of honour.The same age group now has smart phones and tablets, which are about as far removed from a Spectrum or BBC Micro as it's possible to get in terms of how the user interacts with it, and how accessible the underlying hardware is. For this, I really feel sorry for them.Some other skills - PCB layout, for example - are ones which I'd never have come across before I graduated and went into industry. Routing boards was one of my first jobs, but I had to be taught how to do it by a senior engineer.Thinking of the skills I had back then, and how I gained them, I can't help but feel today's EE students are at a tremendous disadvantage. They can't be upgrading their phones with custom hardware, nor even learning much by cracking them open and looking inside.How do they learn?

content: Quote from: george graves on December 15, 2014, 04:54:26 amI have to agree. Personally I have 3 associate degrees - computer, electrical, and electronics engineering technology degrees, and a BS in Electronics Engineering Technology. I've won a national engineering contest from one of the largest semiconductor manufactures out there. I've done private consulting doing digital design engineering services (design, prototyping, PCB layout, Auto CAD 3D Layout, testing, and firmware development - assembler code not C). I worked with finding suppliers for PCB board production, as well as parts and supplies. I am fluent in web design, and network setup and layout. I've done work doing Indy film production, from camera operator to lighting design and programming, to stage and set building. Also for the film work, I designed and built any production automation devices or other technical props where things move (think electronics and the such, to things like squibs for bullet hits and simulated gun fire hitting objects, as well as animated figures). I was heavily involved in the editing of the digital footage as well.Still my current employment is outside of electronics (I work in mechanical maintenance currently), and as such I would consider myself an electronics hobbyist as I do not currently make my living doing engineering work.Would I qualify for your position? I would surly think so. I don't do much PC coding as I don't enjoy it, and I would rather do my embedded code in assembler than in any form of C any day of the week. Yes, that means I have less portable code. So what? I'm not designing things to move from controller to controller, I'm designing things I like to build. I can program in C, but resent to doing so.I've put in the time and practice to learn these things. I've been interested in these topics since grade school, and knew what I wanted to do as both a job and a hobby since middle school. I spent the money on my own lab starting in High school, and by college I had a better analogue and digital lab than most colleges have. I've spent a ton of cash on both my own lab, as well as my education.But here is the bottom line - do you really think the skills listed above should pay less then a sign flipper on a road crew? Last time I was working in the electronics filed I commanded a very nice salary, in the mid-low 6 figure range (USD, not Peso's, Yuan, or Iraqi Dinar).If you want to pay someone an interns pay grade, then I would expect you will have a hard time finding someone with all the skills you have listed, willing to work for peanuts. Even if they are "just" an "electronics hobbyist", if they have all the the skills you have listed, then I would expect they would want to get paid fair market value for their knowledge and the skills they bring. What you are asking for is a junior engineer, a programmer, a video production assistant, and a shipping clerk. What you are offering to pay is peanuts.I would point you over to "The Ben Heck Show" - you know the guy who made the funny barn yard animal toy play sound bites from you. He has 2 people to help him in his shows. One for video production and all around general non-technical helper, and another intern with some technical skills. Both do some very light "on-air" work. And I doubt that either works many hours a week. While I do not know the guy, I would speculate that the technical helper would not qualify for your job description, nor would he work for less than a sign flipper.

content: I think it is reasonable to expect the range of skills stated from someone with interest and enthusiasm for electronics, but maybe not from someone that started college with no electronics at all, unless they've become interested enough to learn stuff outside of their college course.By far the most important thing is enthusiasm and ability to learn on their own. There is no shortage of learning materials nowadays, and hardware is cheap and available.

How to connect a BTTF timeclock with the wrong polarity? Just kidding.You want an eager smart apprentice, so look for one who fits 60% of what you asked and teach him the other 40% on the job.

content: This wasn't too much of a surprise to me. I think what Dave was asking was totally fair and are the qualities of a serious electronics hobbyist, but the fact is, most electronics hobbyists today are just "casual". They are in the hobby just to hack something together when they want, build a circuit that they've found interesting, build a kit, etc. Usually the "serious" hobbyists (the ones Dave is looking for) are the people that want to become EEs like me, and absolutely love electronics (and everything surrounding it).

content: I agree that most students in the third year of electrical engineering at my university don't have the skills you ask for. This is because they see electrical engineering as school stuff and they do not want to do anything as a hobby.However: there is a group of people who really like parts of electrical engineering and that group does have the skills you describe, they are genuinely interested in electronics and they build their own projects because they think it's fun. It is only because of this that they have (most of) the skills you describe.During the electrical engineering study at my university you won't learn how to do any IT thing at al (but: the IT of the EE study association is way better managed than the IT of the informatics study association, because some people think it's fun to do and they DO have the skills you talk about). Same for a lot of other skills: the university won't teach you how to design a PCB. The only thing they teach you is theoretical knowledge, mathematics and other skills like writing a thesis and working in a project group. The real, practical knowledge is something you only learn because you want to, not because the university tells you to.You don't ask too much of students, you just have to swipe away the large stack of applications from people who do not have the skills you will find in real hobbyists.By the way: I like the new blab video's(Edit: There is also a big difference in what I call "hobbyists" and the so called "tinkerers". Tinkerers do not know any theory behind how the stuff they are building works. Even in the hobbyist group there is a huge difference between the knowledge of individual people)

One "hobbyist" designed and built a GPS tracking balloon (difficult at high altitude) with photos, two way command-control radio link, arranged permission with all the Authorities (very difficult) at about age 18.These very capable guys / gals are out there and need / deserve support.

All the electronics jobs were going to Japan at the time so experienced engineers were loosing their jobs, there was no hope for a inexperienced recruit.On the other hand the computer industry was growing massively and there was a great deal more opportunity for employment in IT so that is where my career path went. I also have no regrets as I joined an internet company in the early days of the internet and it was exciting to be part of something as it was developing. Electronics remained for me a hobby but with the explosion of cheap Chinese made products that meant you could get practically anything ready made for a fraction of the cost of building something meant that rarely would I get out a soldering iron during the 90s & 00s.Fast forward to today and thankfully there seems to be somewhat of a revival of interest in electronics but it is different to how it used to be. You can make some quite interesting things with the most basic knowledge. You don't need to know Ohms law to make an Arduino board play a tune. It was this growing community of people who started off making an Arduino play a tune or flash an LED that reignited my interest and even resulted in a big career change for me that resulted in buying the remaining parts of Tandy from RadioShack to get back into the Electronics business.

content: Funny thing is - you think yourself way behind the others, looking at all the cool projects around.But then Dave makes a rant, and turns out your skill set is quite a bit above average.Perhaps the problem is that people see the requirements like "laying out the board", think about a couple years of classes and thick books describing al the tricks and potholes, and conclude that it's a professional skill?Meanwhile, a hobbyist just goes head on into the trouble, oblivious to it's complexity.Like i told in that stillborn thread:https://www.eevblog.com/forum/chat/how-you-got-into-electronics-tell-your-story/On the ZXSpectrum childhood vs Iphone childhood - i can't help but notice that it's a problem that teaches, not capability.Few things motivate a child to learn about electronics better than a broken game console and a desire to play on it.What can break in an Iphone?

And by most I mean >95% of fellow students I met. I could count fellow hobbyists on one hand.My straw poll was always "do you read EA?"Quite a few computer geeks though.Word quickly got around that I was the guy that knew it all and could get your lab project going when it didn't work.

content: Quote from: Artlav on December 15, 2014, 11:52:06 amThis is the same with most things, in the early days when a technology is emerging it tends to be understandable to an individual. But as the field develops things get more and more complex where only professionals can understand and even then usually a team of professionals each with a different area of expertise. The ZX-Spectrum could easily be designed and built by a single engineer but an iPhone requires complex mathematics with impedance matched connections and paths on the board laid out to minimise RF interference etc. Not something someone could just take apart and tinker with.

You are unlikely to find someone who can test and troubleshoot and lay out boards, but can't design basic building block circuits for example.Ok, but someone might be crap at documentation for example, or firmware, well that can be taught and/or not necessary.

The majority had no idea how a resistor looks like or how to read the color code. To find the gems, ask them about projects. Ask them to bring a project to the interview. Makes also a good topic to talk about.

content: Quote from: mikeselectricstuff on December 15, 2014, 10:15:51 amMike has hit the nail on the head, it's all about enthusiasm!When I was studying I had high enthusiasm for electronics, and as Tandy pointed out there was not much in the way of industry for EE's, so I focused more on software development, however I never lost my interest or enthusiasm for electronics and I am now doing both software and hardware design and engineering.These days being around it all of the time, my enthusiasm kicks back in when something breaks and I need to find out why, the rest of the process like design etc, is mostly the same stuff over and over again with a few improvements here or there. Occasionally I will make something to kill the monotony of treading over old ground, and I think as long as I can get my occasional kicks from it then I will still maintain interest.I have noticed an increase trend of companies buying more off-the-shelf now, maybe due to the likes of the Arduino, nobody has to think or engineer anything anymore, they just monkey along.I sometimes program my PIC's in assembler for 2 reasons.1. To confuse the "new age" engineer2. To get that warm fuzzy feeling of working with the actual chip rather than a set of libraries put together by some muppet.I don't know what it's like in Aus, but in the UK the level of what they spit out of Uni these days is diabolical!You do get SOME that are worth more than given credit for, but from my own experience they are very few and far between. I.E. I don't consider getting a Arduino or RPi to blink an LED becoming a "EE", it's definitely a start but most stop there as it is "too difficult".

A games console, or an iphone, or any other piece of high volume consumer electronics for that matter, is a terrible thing to have to understand or debug. They're built from single-purpose BGAs attached to multi-layer PCBs, with little or nothing to probe, and certainly no room for customisation or upgradeability. I'd look for simple mechanical problems, then maybe try searching the internet for the symptoms, to see if they point to a fault that someone else has already identified. If that didn't work, it would go in the bin.Hardware modification is no longer learning, experimentation, enthusiasm or support for the platform, it's "tampering". Try, for example, to add a memory card interface to your phone, and the physical inaccessibility of free I/O pins is the least of your problems.

I'm sure there are many hobbyists that have never laid-out a PCB and some that have never moved any of their projects off a breadboard. If someone spends a portion of their free time studying electronics and building-up circuits because they enjoy some aspect of it, I would consider them a hobbyist. What I wonder is whether anyone would take the term hobbyist even further than I have and include people that simply study and use electronics, but aren't willing or able to do any detailed hands-on electronics work.

So what's the matterAs for payment, personally i would have choosed work for EEVblog back in the uni days than working for a software. That could easily be the same order of payment (some companies will pay you really a low just because you're too young, even after graduation, pfff!) but degree of enjoyment would have been unquestionable orders of magnitude higher! Especially if you let the guy to access the lab outside of the official working hours (like in the evenings, weekend etc). That makes the lab really attractive for hobbyists alike, imo.Anyway, just my two cents, feel free to disagree.

I've done interviews with "software engineers" who wereunableto draw a UML class diagram. (For all the hardware peeps out there, that's kind of like an EE not remembering the symbol for a resistor.) So yes, the idiots are out there.But still, I feel that being a techhead has become synonymous with being a grumpy, grinchy old guy who goes on and on about "these youngsters these days".Thing is, I think today is a much better time for electronics hobbyists than, say, 10 or 20 years ago. I feel that many people lost interest in hardware around the time computers really exploded. I also felt that software gave you unprecedented horizons, instant gratification, without any of the ferrous chloride, broken drill bits or burnt fingers.Today, you only need to mess with ferrous chloride if you really want to - etching your own PCBs have become something like developing your own films. Something you only ever do if you really, really enjoy it. We have all these microcontroller and embedded computing development platforms like the Arduino, Beaglebone or Rpi... We have hackerspaces. We have open source hardware. We have the Internet for sharing knowledge.It really has never been this good.Of course, partially because of the above, the entry barrier is a lot lower than it has been. We have lots of "makers", a good percentage of whom are, actually, artists. You can be a "maker", design and build functionality, without having decent hardware skills. You can "fiddle" with hardware in the way you could do it with software back in the day. It's important to understand that this is not a drop in the quality of hobbyists, it's simply a new population that has entered the field.(Some people look down on this, but hey... Look at all the awesome software people there are today. They all started out coding away like monkeys when they were young.)

If you understand OOP, you can draw one. Like if you can program procedurally, you should be able to draw a flowchart or write pseudocode.To put things in perspective, most of the software I've worked on started its life as a sketched up UML diagram on a whiteboard, with people drinking coffee while shouting each others' head off, erasing and redrawing portions, etc., well before a single line of code has been written by anyone.A class diagram allows you to deconstruct the problem domain, see the connections, understand what is what. I've seen too much software that was written without the creator taking the time to understand all that.

content: Quote from: Sigmoid on December 15, 2014, 04:11:48 pmI was programming C++ even before UML was a concept and we managed fine.That said I've written plenty of UML documentation and even if someone knows how to create class diagrams most don't know how to do interaction, state or activity diagrams.But really why worry about UML class diagrams, there are tools for that (I believe Doxygen does it for you automagically), it does sound strange that your job has a requirement for it since anyone can learn class diagrams in a couple of days and if they are used at work then they won't forget, but since most places won't even use them, then it's ok to look it up when needed.I remember having to download the template separately in Visio for the longer time, I think it finally comes installed by default.BTW do you actually use UML at work?Edit: and as for "being kind of like an EE not remembering the symbol for a resistor" that's just plain wrong, flowcharts are the common ground symbols. There are numerous other diagramming models out there each specific to specific tasks and industries.

We don't produce these idiotic database systems, we produce embedded design controllers for traffic lights (amongst others) and that was started on the back of a dell keyboard box (I lost my notepad), CPLD, core logic, etc, no diagrams whatsoever done for that lot and it works just fine several years later.And as others have mentioned, back in the day we didn't have UML.

We're talking about being able to draw boxes with names, and draw differently styled arrows between them! I mean if the guy had just mixed up arrow styles, I wouldn't have batted an eye... He didn't know where to start.Also, as I mentioned, in my professional life, class diagrams have been a principal tool of communication, and usually come well before the first line of code. (In fact I generate a lot of codefromUML at my day job.)Quote from: miguelvp on December 15, 2014, 04:39:16 pmWell depends on what you're doing. If you're thinking at the level of algorithms, then yes, flowcharts are the basic tool. However, in enterprise application design, before algorithms comes domain. (As in, the real world problem you're trying to solve.) You need to knowwhatyou are doing before you can think about the how.I can't imagine doing that without some kind of class diagram.If flowcharts are tactics, then class diagrams are strategy. And yes, there are other diagram types. If someone can draw up the domain in ER diagrams, I'm okay with that, even if it's another world. But in cases where you're doing something more complex than a blinking LED, you need domain analysis, and if you have more than one person on the project, you need a way to communicate the design in its entirety.Software design and programming are not quite the same thing.

I see where you are coming from.In telecom and networking, requirements are pretty much standard I believe. I wrote my thesis in the field of telecommunications network design.In data heavy application design, you have a gaggle of bankers / traders / clerks who try to explain the requirements, while contradicting themselves every second sentence, and in the end you need to deliver something that will make their lives easier. There are fewer challenges in terms of implementation, but a lot more in making sense of what you're trying to build in the first place.What I tend to very much disagree with is people stating that time spent on design and documentation in software is time wasted. I had a professor at the university who called people like that "keyboard monkeys".

Just look at all the examples out there on how young players have been able to do amazing things on limited budgets, surprising all the experts!In the world of computers, just think of all those young programmers who designed and built computers in their garages, made amazing software, squeezing ridiculous performance out of tiny codebases (e.g. "Demoscene") and pioneered many of the advances that we attribute to professional corporations today.In the world of electronics, there are many young players who "GOT THE RIGHT STUFF".The *ONLY* limitation here is physical distance.If you have trouble finding someone local who meets your criteria, why not "out-source" to someone who lives further away? Video conferencing, recording and uploading and sharing video, source code, PCB layouts, designing, trouble-shooting, shipping components, etc... all of it could be done over a distance. How feasible would it be to hire someone in a different country?

I have a home lab that I have put several thousands of dollars into, as well as a few pieces of gear that I have designed and made myself.Due to my ever growing interest in electronics, I thought it was time for the degree. Fast forward to now and I have just recently (less than 2 weeks ago) finished my second year at Uni doing EE.I live close by to Dave and have met him previously, and I now work casually (before Uni, was full-time) at a previous employer of his.If I were not at a highly supportive & respectable company I would be applying for this position as I can imagine learning a good deal from the experience.I don't think the demands are too unreasonable. However, I will reinforce what has already been said in regards to EE students who simply don't give a damn.I will also second the idea of a semi-retired engineer (engineering assistant) who is looking for some casual work.I believe there is a person out there who is fit for the role you're offering and I wish you all the best in your search.Jason

content: I think you are a bit unfair when you compare your skill-set back in the 70's and 80's to what you expect now. Many things have gotten easier for sure, but also way more complex - not unlike software engineering, where the abstraction levels have also shifted and where specialization is favored over generalization.For instance, I consider myself an EE hobbyist, but I decided CAD board layout is NOT a skill I need. That's because I can (out)source this specific production aspect dirt cheap and spend my energy on engineering/experimenting. So while I am sure there are hobbyists who can do everything you ask, I'd argue they could get a better paying job elsewhere - which means it really comes down to what your brand can attract.

PCB design, for example, is essential for mass production. But one could be a very capable RF hobbyist without ever making a PCB, dead bug construction will usually do the job just fine for one-off projects.And don't forget, the difference between amateur and professional is if you're getting paid for it or not, it needn't say much about the level of skill involved.

content: Are electronics hobbyists useless? My short reply is absolutely NOT! I am 68 years old and continue to enjoy electronics as a hobby in all forms and I started as a hobbyist in possibly 1958 when I built my first vacuum tube stereo receiver from a kit...I was hooked on electrons from there onward. As a kid I hated high school except for shop and an electronics class available to me, and I later chose to go to a two year technical school graduating as an electronics technician in 1967. Electronics turned me in a productive direction from that point. My path has been a long and enjoyable one in the work force as a US NAVY electronics technician, TV service tech, and I finally retired from Texas Instruments Linear Circuits Division in 2005. Unfortunately my health prevented me from working long hours there further. I miss working in electronics but I discovered Dave's stuff on YouTube two days ago, and I love the updated information I get from him. Watching Dave's material has reawakened the electronic adventurism I once had. Being retired now allows me the time to tinker and experiment again. I cannot imagine what I would have done in my early life if I had the internet and blogs like this to learn from. My only regret is that I did not go onward to get my Electronics Engineering degree, but raising two children and providing an income somehow got in the way. I encourage anyone who considers that being a hobbyist is a waste of time to completely reconsider that thought. The demand for such skills has never been higher! Even if you don't make a career of it as I did. Thanks Dave, for all the enjoyable and educational YouTube material!

content: I guess I am just confused by the somewhat provocative and sensational subject line Dave used. My understanding of the term "hobbyist" matched what wikipedia defines: "Generally speaking, a person who engages in an activity solely for fun is called a 'hobbyist', whereas a 'professional' generally engages in an activity for reward and an 'amateur' (from French for "lover of") does so out of personal interest in an activity. While an amateur may be as skilled as a professional, a professional receives compensation while an amateur generally does not." So by definition, a hobbyist can not be useless since he is doing stuff for his own pleasure.

content: Quote from: IanB on December 16, 2014, 02:44:22 amYour right, I had to deal with 2 counterparts at a subcontractor and while they seem to have specific skills in one area all round they were a disaster and I had to keep fixing things and telling them how I made their stuff work so that they could make a better one and their only interest was in the little PCB and not in the whole design despite the idea being that they eventually manufacture the complete product infact despite us requesting production intent prototypes the results are going to be a nightmare to manufacture. They were totally uninterested in listening to my ideas and using concepts I had already worked out that worked best with some tricky hardware, result more problems.We are now working with another person (not same company) who is very passionate about what he does, I have no idea if he has qualifications but he certainly has experience on the job and it's a pleasure to deal with him because if I make a suggestion or throw him a line he understands what I'm on about rather than looking at me blankly. Unlike the other we can discuss the fine detail of how our hardware works because he grasps with ease the limitations and the little things we can use to our advantage to make things actually work rather than sort of work sort of like we wanted. Nothing is perfect in the real world and those who are wiling to understand how something does and does not work and maximise any little advantage are the ones worth it, those who want to plug something into a uC and see it work are the idiots we don't need.

content: I'm quite partial to a bit of the old Vero board, more formal than a breadboard I think! And I don't have to remove it when I want to build something else. There are the downsides of not being able to reuse components or board of course, but given the choice I would Vero board it every time.BGA's don't tend to Vero board very well and you do need a custom PCB, as well as many other modern SMD components with tiny pin pitches and a lot of them, so I think PCB design is essential for most hobbyists, just a shame they didn't teach it very well when I was at college.

Hence some of the "text book" implementations I have seen that do not work in the real world.How many times have I come to this forum to ask advice and gone away much wiser, many don't have this capability of seeking peers advice.

If Anyone gets on in the field they need both of course, but there are plenty of people who supposedly have the knowledge but can't use it, they are admired for their smarts on paper but their practical design work is disastrous. Likewise for a self taught person to do well they still need to learn the theory, but the practical side of it is assured and they have to work much harder to get anywhere and know their theory as opposed to the guy with the piece of paper that gets by by having the piece of paper, the self taught one has to have a WORKING knowledge of theory.I have nothing against qualifications and am starting to study them myself as my employer seeing that I am capable and they are using my skills wants to make sure I am covered by the theory i need and can be very useful to them and it's probably a sort of reward as they don't need much electronics but they know it's what I'm bent on and it can be handy to them. I obviously have the aptitude, but I too need to learn lots more than i already know. I have slowly acquired respect from my employer and collegues by demonstrating over a couple of years that I actually know what I'm doing and can put my money where my mouth is. Had i come in with qualifications I would have got automatic respect with no questions, I'd not have had to save the day a couple of time from our incompetent sub contractors and saved them a lot of money and made available the ultimate flexibility of having an in house man on the job that is competent.the sub contractor with post graduate employees is not looking so good anymore as they have frankly fucked it up time and time again but of course I'm not saying that qualifications mean you are no good

This was back around 1969-70, or so. I got my first job at Mouser Electronics (back when it was a small import company based in Lakeside California) by identifying electronic components on a board. The job was for a warehouse picker, but I did so well on the test that I got to meet the founder, Jerry Mouser, who gave me a job designing educational electronic kits to sell to schools in their catalog. I had to design the circuits (mostly adapted from magazine articles), etch the PCBs, write, typeset and print the manuals and then package the finished kits. I was 19 at the time and had no formal training other than being a "hobbyist".Wayne

Absorbing facts and being able to remember them to fill out an exam form is not the same as having the ability to develop a good understanding and the ability to think things through for yourself to arrive at a solution.Education should teach people how to discover, process and apply reason to information rather than just teaching facts. For example you can teach someone that 6x6=36 so they can answer that question on a test form but it is pretty useless unless they understand how multiplication works so they can answer any multiplication question not only the one they have memorised an answer for.It really comes down to aptitude, someone who has a keen interest in a subject will typically be motivated to keep delving deeper into something.

Because, I believe one should understand what he is doing rather than just follow some steps. I don't talk about finding how to change some configuration bits of the microcontroller or something like that, but to understand what microcontroller means. And this applies to doing electronics circuits.I can not believe that people do good working projects without knowing Ohm's law xD. who said that is somehow over-estimating it.___I read a bit of the discussion about theory's importance... look, I've seen and met professors and master degree engineers who can describe complex electrical drive methods/circuitry, simulate and analyze it via MATLAB, and such stuff.... but they can not put one practical example of it!Not only that, some of them may don't know how to program a PIC or an Arduino. Or talk about a design task like it was nothing! they just say: "Do this, and that... then you have that" << this is the typical behavior of someone who doesn't have ANY practical real-world skills!They assume stuff will work fast just by following some typical circuits in textbooks with some tweaking. So, don't blame new engineers that lack some of these skills today because that is the type of education they take (or nearly like that).I myself learned programming PICs by my own... along with all skills (not much fancy) that I have now. because relying on textbooks will take you nowhere!Don't get me wrong, theory is essential and important. Just it is not everything.

content: Hi, Dave. I think it is not a problem for hobbyist to have all those skills. There is a different problem: this is kind of expensive hobby so such hobbyist is probably already fully employed, and barely has some spare time for practicing electronics. So he or she would not be interested in this position due to lack of timeTake me for example (we met last year when I was in Australia) - I'm a purely-software engineer in a large software corporation, and I practice my electronics hobby at home. I have all skills you need, and if I was not a half world away from you, theoretically I'd be happy to help you for free. But in practice comes the question of free time - I'd not have a lot of it and most likely when I have free time this will probably not coincide with the time when you need help.

But as electronics has a long standing history of someone specializing in one area and assuming they know everything this bled over very fast and basically it's a case of just because someone showed me how to flash an LED and told me to use a 1K resistor I can now do this and I don't need to know anything about how it works.I gave up on the arduino forum when I got things like people insisting on the wrong way of applying back emf diodes and claiming they worked on aircraft systems.Programming one thing and a vital skill, electronics is a collection of other vital skills involving analogue, digital and the practical applications of both.

content: Heads up, Dave!There must be at least dozen of students/hobbyists fitting your requirements living nearby, what you are asking for is not unreasonable at all.You might even consider adding requirement for basics of programmable logic design, if you are seeking for someone in the higher end (read: not lazy to learn).Such people do exist, only thing is to make it interesting enough for them - sure, publicity and valuable point on resume is something, but what range of project can one expect to work on as lab assistant? You are quite vague in the definiton. Such people, if bright enough, will be sooner or later noticed by someone from industry and be sure they will happily take any field related job when offered. Once bit more expirienced, they will be more and more picky and tend to choose only work related to topics that interests them - so offer something exciting to tinker with, not only vague "what suits your capabilities", then it's on to you to evaulate candidates if they are capable enough to fullfill project goals.I'd always go for something that interests me even if it's paing less in multiples of what I can earn with my skillset - just because then I can fully enjoy my work and in the end it was all fun. As bonus there are new skills gained with minimum effort required. Another factor I value much more than money is work collective - working with enthusiastic people having same taste of humor as me is priceless, bonus points if it is small garrage company and we are all acting almost like a big family.BTW: one mistake I see repeated over and over around me - Why do people expect to be taught anything by a school?Teaching or learning something solely based on memorising facts instead of fully understanding them and applying them and hence encouraging student to be interested in more details is utter nonsense, but not uncommon at all - schoolar system can be fairly regarded as broken in this way.Also, students will choose path of least resistance in most cases - why would one bother to understand, when memorising random facts is enough to pass exams? And this applies all the way from elementary school up to the college. I'd bet you will choose someone who's fully, or almost fully selftaught, (just) because it's this way nowdays.Before one starts flamewar based on my post - I'm not trying to sound like elitist dickhead at all, I'm just summing up all my up to date expirience and my viewpoint leading from it.To be more detailed on my backround: I'm in my early 20's, working for small company focused on highend chemical instrumentation, doing all suff related to hardware, including low level firmware, HW design (from concept trough prototypes, verification, PCB layout, HDL design all the way up to manufacturing preparation and material sourcing), almost all of the mechanical related stuff (or least doing documentation for third party companies). Other guys do rest of the firmware and software work, bureocracy, chemical research and so on. Previously worked about two years for another small company focused on LED technologies - some of it was medical, some aftermarket automotive. I've got my first serious paid project back when I was 16yo teenage.And you know what ? I'm selftaught. I know about at least three other people in my age brighter than me in our region (and that's about 200k of people in total and fairly limited by my social awkardness), all of them selftaught, too. Such people exist. Just keep looking and make it interesting for them (I'd apply in a heartbeat, BTW - if only just not living on the opposite side of the Earth).

content: Sorry Dave,I wouldn't have qualified for your position either back in the day when I first began studying electronics in the 1960's. My breadboard consisted of a 1' x 2' piece of 3/4" pine with a traced copy of the schematic from a magazine taped to it and some small finish brads to use as solder lugs. I didn't learn my first professional layout tool, PADS/Mentor Graphics, until the mid 1990's after working as a technician (shipboard radar and communications) for well over 20 years.I was taught DC and AC circuit analysis (using a slide rule) , troubleshooting, instrumentation, and layout using pencil and paper drafting skills, blueprinting, and tape out.If I was looking for help again, I would do as I have done in the past and look for some one that could at least do DC circuit analysis and knew how to use the standard word processor and spread sheets, which in my part of the blue marble is Microsoft office. The important thing to me is that, in addition to the above, the candidate have a can do attitude, strong work ethic, and tolerable personality. The schematic capture and layout of minor non-RF 2 layer boards can be learned quite quickly. The same can be said for soldering. Well, that's my opinion for what it is worth. (PS If some of my words are miss spelled, please cut me some slack not only am I an engineer, I'm a Yank and English is a second language.)

content: It comes down to two things.First, if you want a candidate to have a skill, it should be because you want them to utilize that skill, and therefore they need to be fairly compensated at fair market value for having and using that skill. Otherwise, they won't stick around long or they won't perform - and you can't really blame them for either if they're not making fair market value. There are exceptions like internships, work-study, lab assistants and such, but this is a "real" job and those exceptions don't apply. Finding someone with all the skills requested who is reasonably proficient in those skills isn't impossible - but the pay will need to be commensurate with that experience. We don't know what they pay is so this isn't a criticism - I assume we're speaking about a pay level that matches the skillset being asked for.Second, a very very successful man in the oil business once told me "Don't hire the best. Hire someone good enough". That was in response to my first business plan which involved a Star-Trek-like idea to hire the best and brightest group of brilliant over-achievers I could find to build an unstoppable team. He advised me against it - and he was right. The problem was that such a group of brilliant people with lots of skills and experience in various fields wouldn't want to be working for my little startup unless they were hard up, and/or they would work there for a short time and turn into a competitor or leave when something better came along. My friend suggested that if you want to hire an accountant, then hire someone who is happy to just be an accountant, not someone who is a brilliant financial mind with some proficiency in sales, technology and engineering. That guy won't want to be "just your accountant", and you need "just an accountant". In other words, it's important to define what specific role the employee is expected to fill, and ensure that you hire someone who is good enough for that role (at that pay), rather than someone who is the very best you can find. Nothing is more of a hassle than getting a new employee up to speed, so you need someone who will be happy with the job (and pay) being offered.

content: I believe the general description Dave lays out for a possible employee is perfect. The description, however, is not describing an undergraduate university student since for the first several years these students are largely taking building block math (calculus 1, 2, 3, 4, linear eq, diff eq, etc) and electives (the humanities namely English, psychology, sociology and all that) or engineering drafting ( God forbid!). Electronics training for an undergrad EE at this point is vague, nil and largely has very little to do with the pragmatic hardscrabble skills and insights displayed throughout and requested for the EEVBLOG.Rather that perfect candidate will most likely be some naturally passionate, over the top obsessivly curious, slightly nutty electronics hobbyist with a lab in their bedroom in addition to a practical trade school background, and still at this point, probably vying for the more worldly university degree. A misanthrope would probably fit if they thoroughly understood Ohm's Law, and while growing up, had dismantled every clock and computer in their neighborhood (treasure) while looking great in a bikini (think video presence and mud runs).

content: Look I tend to agree with Dave's description for the role. It is the difference between an enthusiast and a hobbyist. I would say I am an enthusiast, I love to tinker and learn about electronics and fix things that are broken and can do diagnostics of basic circuits, but I couldn't design a PCB layout to save my life (mainly because I am not in a position where it requires me to actually make any money out of it or try and find my first job in the electronics field). I loved mucking around with circuits as a youngster, building also sorts of stuff from the old Dick Smith Fun Way into electronics and old Tandy electronics books in the late 70's and early 80's, and hacking hardware (especially 8 bit computers of the era) but circumstances led me into other careers and I never pursued electronics until more recently despite my passionate curiosity for the subject and likewise be reinvigorated by websites such as the eevBlog.Still having all the enthusiasm in the world doesn't mean I am of the caliber of a reasonable hobbyist who has been making many circuits at home. While I can solder, use various test equipment and understand basic electronics theory, in my limited experience and probably still ignorant opinion of the subject it is the difference between home theoretical electronics and practical applied electronics (or simply understanding vs doing) where you see the step change. The next for me would be hobbyist to undergraduate university student where the hands on skill meets the advanced theory and solidifies why the hell those things you built actually worked, and turns on the lightbulb why many of them didn't (despite you figuring out that adding/substituting higher value components here and there seemed to solve the problem in one of your hobby circuits).

And based on their resumes (what ones I've read so far) and other stuff they have sent me (public projects, videos, crowd funded project links, websites etc), many seem very talented and well suited. And they range from hobbyists, school kids, EE students, graduates (up to masters), industry experienced, and even retirees. There seems to be no shortage, even knowing up front that it was a not a high level experienced industry paying job. And yes, the majority of them have most or all of the things I'm asking for.

I also started electronics experimenting in the 1960's as RogerS did with about the same type of gear. I think a retired electronics repair person, like myself that carried a scope and tool bag from site to site for years and had discrete components in the trunk, would make a great side-kick to the blog. If I were not also a yank, would have applied when the post first came out. Any person that has practiced electronics as a hobbyist should have the skills mentioned if they do anything at home for the pure joy of it. Otherwise, how would you get to do anything except read and wish? My two-bits.

He saw that the existing craft design was "suboptimum" from a theoretical (and operational!) perspective. His use of maths gave Spitfires, Hurricanes and Mustangs an extra 30% (!) power (i.e. improved climb and height) and 22mph more speed.Without that maths and theoretical insight, the Battle of Britain would have been lost and my German would be much better than it is.Theory without practice is mental masturbaton. Practice without theory is alchemical fumbling.Both theory and practice are necessary; neither is sufficient on its own.http://www.historylearningsite.co.uk/sir_stanley_hooker.htm

I've gone to lots of conferences and training seminars and there are a LOT of gainfully employed engineers out there who aren't able to do all the things you mentioned a hobbyist should do - I don't think there's anything wrong with that really.. it depends what their job requires. It's OK to have a lot of depth without much breadth... or even not a lot of breadth or depth - if you're able to do the job required. I think anyone who is doing professional 12-layer PCB's running at Ghz with top level design rules are very specialized folks who would never be also expected to write firmware, hand-solder and such... they might not even be the same person doing the schematic! I think that if someone has skills that are commercially valuable, it's probably not fair to call them a hobbyist - aren't they then a professional by definition?Anyway, it doesn't really matter - if you're getting resumes then clearly there is interest and hopefully you will find someone good. It sounds like your job is very non-traditional in many ways, and there is a subset of workers who are interested in such jobs.

Wackypedia's Merlin entry can be read either way. Hooker started on the supercharger in 1938 and the major result (the two stage supercharger) was immediately post Battle of Britain (i.e. Oct 1940). But my memory and suspicion is that he contributed to the single stage supercharger used in the BoB.Either way, it doesn't detract from my contention that theory is as important as practice; either alone is much less useful.

In the end those that are, and those that are not still end up with good paying jobs and their employers seam to still like them. I consider the true hobbyist to be on the high end of the skill set but not at the top professional level. The true hobbyist vs the enthusiast will have almost as much knowledge as that seasoned professional but not quite. I consider Dave the true hobbyist that turned professional which in my opinion produces some of the best in any given field. The exception of course might be medicine where they frown upon hobbyist.I would suggest taking the most important skill sets and trying to find a candidate that can fill that more select list.

I'm sorry but your being very dimisive of competent people and assume that competence gets you a qualification.I have no chips thank you, I am just an attentive observer of the world around me.We comissioned a guy to design a control board for a safety critical application, by safety crtical I don't men if it fails a car crashes, I mean that if it fails someone dies pretty quickly because it's practically life support, what did the clod do ? he drove a mosfet with 28V when it was rated for 10V and 20V ABSOLUTE MAXIMUM!!!!!!!!, result the systems (fortunetly only on prototypes) failed. Despite me pointing this problem out on his first version he did not correct it on his second version where they failed again.I have no qualifications but I'm intelligent and reasonably knowledgeable and was suspicious as soon as i saw his diagram. Because I have used the required level shifting circuitry so often myself I was immediately drawn to the lack of it, this is peoples lives we are talking about. He had never even heard of a logic level mosfet, his PCB skills were a disasterSo far my employer has used 5 subcontracted engineers, 2 were conmerchants, 2 were useless and one seems to be very on the ball and a pleasure to deal with.When a guy comes to you and moans that your thermistor you gave him to use does not have enough resolution (to flat a response curve) and you ask as you know he is using AVR's how many bits he is using and he says 8!!!!! you can eitherorthere's just no hope!

A HNC is the highest qualification i can go for without prior qualifications and although technically a L3 is required they are happy to take on people with some prior experience in the industry. After a HNC I can do a HND, i think that is as far as I will be able to go with employer support and personal motivation as after that you are talking a full on degree.

So the problem was that measuring ambient was difficult because the change in voltage on the resistor was too small for the ADC to pick up.But when your being a clod and have a 10 bit ADC and insist on using only 8 bits and then ask that the NTC sensor is changed so that it will work with 8 bits because your too stupid or incompetent to use the full 10bits you already have then it is sad. I spent a few hours trying to keep him happy only to find that all NTC's behave in the same way and that it's a fact of life, again i learnt and digested quickly something that a so called post graduate seemed ignorant of, because he wanted to plug an NTC into an MCu and have it work, that is the arduino legacy for you!But then I have used an NTC at well above ambient where the curve is really flat and had no problems.....

I find people that don't stretch their capabilities to be boring and, often, completely ignorable.You will find a lack of maths will be a hindrance - I found the maths at uni to be difficult despite having good grades in both Pure Maths and Applied Maths. Having said that, a lot of maths has somewhat "pictorial" explanations and operation, and that may help you.It is worth pointing out a little bit of theory about how to make a successful team. The original research was by Belbin in the 70s, and although it has attracted more than a little bovine excrement, the underlying principles are sound and can be used to guide thinking. N.B. both "guide" and "think" are vital - without those you you have process-following pen-pushers.You will see that my strengths counteract your weaknessesand vice versa.Principle 1: everybody's personality and experience strongly biasses them towards one of the team roles, but they can often fit into a secondary team role.Principle 2: there are a number of team roles, each with required strengths and allowable weaknesses.Principle 3: the team roles can be cut many ways, but the ones I understand are:ideas man: spits out novel thoughts, but can't evaluate their real valuecritic: quickly evaluates ideas in the context of what needs to be done, but doesn't initiate many ideascontact man: continually talks to everybody, acting as a conduit between the team and the stakeholders and othersworker: does what they are told to get the job donefinisher: obsessively dots the Is and crosses the Tschairman: empathetic, causes team to reach a consensusPrinciple 4: a functional team needs all those roles, which thereforerequiresdifferent types of peoplePrinciple 5: unbalanced teams will fail. For example, two ideas men will have a fizzing great time but there won't be any usable conclusion, whereas two critics won't generate anything new. Two finishers will never get the job done, whereas two workers will fill up the time available. Etc.Your strengths counteract my weaknessesand vice versa.And that is why both theory and practice (and the people that embody them) are necessary, and neither is sufficient.

content: I'll give my 2p on this based on decades of experience in EE...A typical and keen hobbyist (but not all hobbyists so please don't be offended) tends to gain experience and knowledge in a kind of scrapbook fashion. Lots and lots of little nuggets of very useful info and experience gained over many years and this can make them appear very knowledgable and even give them delusions of grandeur.But... and it's a huge 'but'... if you take them away from this scrapbook and give them a fresh problem then it often gets quite scary because you realise that often there is nothing inbetween the little scrapbook nuggets for them to fall back on. Often this means they can't apply basic theory to a fresh problem or they simply make up their own version of physics based on common myths. This isn't good. A little bit of knowledge can be very dangerous if there are no fundamentals to fall back on...However, if you look at fresh graduates (decent ones) then you tend to get a fairly blank canvas. Initially they lack the skills and experience of the hobbyist but they can be groomed over time to fill in these shortcomings and eventually the hobbyist will be outclassed in nearly every department. But this can take several years.But you can also groom a hobbyist into becoming a better EE by providing training courses or part time education and this can help fill in the gaps in their 'scrapbook' with some solid theory. Sometimes this can give a real boost to their abilities as they have more and more 'Eureka moments' as the gaps in the scrapbook get filled in. So you end up with a very capable EE but by a different path.At the end of the day we are all human and made of the same stuff...

Try staying calm and professional when a guy wants a better sensor because he does not know how to use the one he has for frustration...... Like I said on a sample of 5 people I have had dealings with "professionally" 80% were not fit for purpose, I'm not saying tnat is across the board but it shows there are plenty of places available for incompetent wielders of pieces of paper, and some of them get to make mistakes that could kill. Never said I was all knowledgeable but it's painful to have to correct other peoples work when they are supposed to be better at you and probably better paid.

content: Well sadly when one has to step in at the last minute to save the day because the paper wielding expert totally screwed it up or can't be trusted and won't do it in a reasonable time frame and with the required flexibility. As i said we are working with a new subcontractor. The idea is not that at the moment that I design these things, but then we have seen what some experts produce it's 50/50 really. As i said I am not too proud to ask and often ask a level slightly below my knowledge as it's nice to have 2 plus people come back and answer as expected and often is develops into collateral discussion that I learn more from and fill those "hobbyist gaps". Ultimately the equipment we work on has a plan B but you need to know a problem is occurring so that you have time to implement plan B. If a system fails outright with no warning because some berk with a piece of paper drove a 10V mosfet with 28V despite being warned it was a really silly idea there is not really much hope.

content: QuoteYup, that's it...Back in 1990 I was incredibly lucky to be able to join a fledgling startup company that was set up by a group of very talented (middle aged) engineers that broke away from a well known UK defence/TEqpt company. These guys were amongst the most talented engineers you can imagine and I learned a lot from being able to sit with them and watch how they designed stuff and how they dealt with problems or new concepts etc.BUT... I also quickly learned that everyone has holes in their knowledge base including these guys and sometimes the existence of these holes in their knowledge came as a surprise even to a comparative novice like myself at the time. But then nobody can know it all.However, I also quickly learned that the key to (company) success is to have a team of engineers across all disciplines within EE and to create an environment where nobody cares about these individual holes. The only important thing is to debate the issue as a team and to find the correct answer. Sometimes it pays to have quite a few people in the room across all disciplines eg HW/SW/DSP/RF/Mech/Test/Production.It's a great way to do things because it helps fill in the holes for everyone in the room.If you fast forward to 2014 (nearly 2015!) you can create the same environment over the internet but the main stumbling block would be if you tried to do it as a text based forum. Text isn't the best way to communicate and it usually causes friction and upset and so communication and goodwill can quickly break down.Back in 1990 I was incredibly priviliged to work amongst those talented engineers that started the company and I know how powerful it can be to get a group of decent engineers in a room with a whiteboard and a few design tools. It's a great environment to learn and share knowledge.

content: First time post, long time reader. I used to be a teaching assistant (TA) in an engineering course of 700 students and 100 teaching assistants. Mixed discipline, but a highly CS/ECE focused school. Candidates like this did exist and our course was pretty aggressive in acquiring them based on measured potential we observed in their course work before the other departments since we were in the intro to engineering course.The hourly wage was roughly $10-$15 based on skill set. The big problem is the students that did meet this set were destined to leave the teaching assistant program within a year or two for higher paid internships $18-$23/hr range. Even I left and I was the head TA managing the 100 students. The course director just allowed me to manage and coordinate the other members remotely.We were glad they left, they were destined to fail in their careers if they stayed since we could only offer so much experience and this young for them to only know the scope of what we did would have staggered their talent and aspirations.One mechanism we had in place for the low retention rate of undergrad/grad students was doubling everything. Every subcommittee of this TA organization from payroll, It, lab management, video, etc had two leads. So a senior trains a junior and they are spaced apart a year or two so there is always a "Master" and "Apprentice." doing this for even your assistant might help if you start losing you new hire every year.

Electronics and making is more accessible than playing the violin but is similar in that to be practically good both need natural inner drive and a talent usually defined as " having a clue."In any endeavor, one ALWAYS needs to be able to visualize it in their own personal way. They can 'see' it. There are many engineers out there with no talent. A frequent poster here once stated how he saw himself as a pilot flying through circuits. Boy, I wished he'd give more insight as to how he arranges the concepts in his mind.If they haven't been doing it, they probably won't be doing it... At least, not on the EEVBLOG.

content: Yes i got in a linguistic twist, your, sorry you're lucky I reread and correct anything i type at least once before hitting post.There seem to be a number of people holding on for dear life to the notion that to have gained a qualification automatically makes one competent and far more worthy of respect and the "job". As already said I have witnessed this not to be the case, there has been talk of having a qualified person in a post it much better than a non qualified one as the non qualified one must be rubbish and the qualified one must be great. This is naturally not so. Few employers carry out competence tests on job candidates that is supposedly the idea of having a qualification and it is far easier to be a paper wielder and get a place your not competent to fill than a non qualified person as a non qualified person in most jobs held usually by a qualified person will have gotten there through proving themselves over and over again.But do hang on for dear life to your qualifications snobbery, I'm sure for some it's all they have to show for themselves and they need it to prove even to themselves that they are competent as well as qualified.As I've always said I also value a qualification but one that actually imparts knowledge to one willing to learn. No matter what your smarts there is always something new to learn and the non qualified person with a hobbyists background can't afford the snobbery of they know it all and no one can teach them anything new, it is for this attitude that a certain subcontractor my employer used to use is out of a job!

content: Quote from: SeanB on December 22, 2014, 09:34:14 pmVery well put indeed. I'm not sure on the terminology and I forget which continent has just decided to abolish the term Asperger's usually your lower level autistics will actually be diagnosed with Asperger's and they can indeed make good engineers. If you take a look at the so-called traditional nerd you will probably find that you are in fact looking at somebody with autism been derided for being a nerd. I think it is now fairly well-known that many of these so-called nerds have actually contributed quite a bit to the technology we use today.The other thing to bear in mind that autism or Asperger's is not a single diagnosis and co-occurs with a number of other conditions particularly dyslexia but also dyspraxia dyscalculia and a few others I can't remember. Usually one never occurs on its own so it's difficult to just stick a label on somebody.A few months in to me starting in engineering my new boss suggested I might have dyslexia when he noticed that I was not making just spelling mistakes but mistakes that I was probably not seeing due to a correlation between visual problems and dyslexia which mean that if for example I type 3 "m"'s it is actually hard for me to see how many I have typed this is usually known as visual stress. He was however quite supportive and obtained a little information to help me on my way. Not being one of the old-fashioned types he knew that dyslexia does not mean you're not intelligent and did not treat me any different not that I was diagnosed in any case although my father being dyslexic is pretty telling.When it was suggested that I do some qualifications I thought oh dear I would love to and I agreed to but I know that my learning experience has not been the best in particular with maths although that was with an impatient teacher in a classroom environment who did not have the time, inclination to help me or see that I was struggling and just put it down to me being dumb. So I arranged and paid for a dyslexia screening to see if there was anything I should know and if they could tell me anything that would help me (remember I said earlier that my biggest strength is knowing my limits). As it happens the person doing the screening looked at me a bit funny and couldn't work out why I thought I might be dyslexic, but this was mainly because it was only the screening and not a full diagnostic assessment which I would also have to pay for myself and is much more expensive than I care to pay, I came out as having a low probability of dyslexia although it was borderline with being some probability and my test also showed not that I can figure out how they work it out that I have a very high IQ as the test is designed to test IQ but not in the sense that most people interpret and I was also not checked for spelling which I had to admit afterwards is worst than I thought. But we did speak for some hours and the person doing the assessment has asperges herself and she said it that in her opinion I probably have an element of asperges which was no surprise at all.If you look around the net for dyslexia screening tests they will warn that people with a high IQ do not always show up with the correct score for dyslexia as they have developed so-called coping mechanisms not that I'm aware of having developed any myself.So there you have it, I know that most people at work and some have told me can't work out how I got where I am to be honest I'm surprised myself sometimes not that it is that far but it's much further than some people thought I would (I beat my predecessor our of the QC department, took him 4 years to get from QC to engineering and it took me 3, he just can't help but feel a sense of competition). And it's not just getting as far but actually getting the job done and being useful in the workplace rather than just another bum on another seat making yet more cock ups. But as much as I have a good engineering intuition and grasp some concepts, I am well aware that I need the qualifications and given the time to study the maths on my own and with a good quality text (no ICS Learn shit!) I am slowly getting there I hope. It has been slightly easier than I thought.I don't know what peoples opinions are of people with so-called learning disabilities, all I know is I am surrounded by people who are supposed to be qualified in totally different fields and even then sometimes I find they can't see the wood for the trees and I can't explain to them what it is they are not seeing. I struggle to understand how some of the simplest electrical concepts I present are seen as extremely complicated even though some of them having being doing basic electrics for years, perhaps I'm overly adapted to having to learn new things all the time and work things out for myself. The most frustrating response I get from fellow engineers is "well I wouldn't understand because I'm not qualified in that" even if you try to explain it to them in baby talk they don't actually want to listen or learn, so it's like i sit one side of the office with my "expertise" and they sit on the other with theirs and they never know when to involve me because they have not the first clue and usually I end up involved when it's a bit late and I hear them complaining about a problem they can't solve.Only the other day I heard a pair going on about sensors "sourcing" or "sinking" and what on earth did it mean but did they ask ? no, I had to interject and explain and they were very happy for the explanation, but did they think to ask ? no they just said, electrical, can't be any of our business.......The sad thing is that society and the schooling system does not support or encourage people with so called learning dissabilties, most people just gather up all of their ego, and call them nerds and put them down.

content: Simon, well done on the studies, you will get the maths up to some good level eventually. You probably want to go get a university maths book, and do it yourself at your own rate, so that you are more confident at self learning. look for a used copy of Calculus with Analytical Geometry, any old edition will be cheap, and will work for you.Funny thing is the maths rarely is used by itself, but the foundations of logical thought, reasoning and step by step problem solving will serve you in good stead afterwards. You are already using those, so a little refinement will go down as a very good addition as well.

My original reply was going to be that the problem was the problem definition.But oh well, let's cut tggzzz some slack, and let us justassume(uh oh) that on an EE forum the socially acceptable solution space for sqrt(-1) is going to be the complex plane. And in that case there are indeed two solutions as you say. But if a problem neatly leaves such details as solution space undefined, well then you can use anything that is valid. And in that case there's a few more than 2 solutions. If you use quaternions that's 6 solutions already:+/- i, +/- j, +/- k. And if you use octonions there still more, which I'm not going to list here. If only because those octonion bastards are non-associative and it's too early in the afternoon for that.But as luck would have it no matter what space you pick, it all fails on an inequality similar to the one posted earlier.Now how the hell did we get from the OP to this?

It's not been as bad as I thought but I'm still not sure I would be able to complete a blind test, the more reassuring exercises are those where I can put my answer back into the original equation and verify which I suppose you can do with all of them although it's definitely an accepted method for the more complicated things like simultaneous equations.

Surely using literally measuring sticks is not what got us to the Moon, Mars and beyond. Math and our basic, but evolving, understanding of the laws of the universe are the primary tools to bring us forwards as a species. Not trial and error using crude lengths of strings, sticks and stones, we left those behind thousands of years ago.

content: Maths is the underlying system that keeps everything working and explains how it works. The problem is that often the way to go about solving an equation can be a little elusive as plenty of options look like the correct one but bring about totally the wrong result and hence it is easy to prove anything with maths if you go about it the wrong way. If you are using these mistaken methods to demonstrate a so-called truth to somebody who is not very well up on maths I could be one of those, you would easily demonstrate something which is completely untrue. A proper understanding of maths will see you through.The problem we have with today's society is that people think that just because they can use a smart phone and that a smart phone exists they are as great as the guy who made it and they don't need to know anything else. Fact is that in this society where most people do not have to work out very much for themselves because of the technology we have people are becoming more ignorant again as they are given tools they do not understand the workings of but they can used to produce a result. Therefore they do not understand their own lack of skill or care because what most people care about is the result not their skills. This is why rigourous qualifications are important and not some of the mamby pamby shit that is handed out by privatised education companies like ICS learn.

content: I was always under the impression that engineering was an practical domain. You can create delightful constructs using mathematics that may be impossible to actually build (for the moment). I think that is the reason to appreciate math, use it as the tool it is, but not to rely on it solely. Like all models, the practical usefulness of an equation is only as good as our ability to validate it against the real world.

content: And until you get into stupidly complex maths most of it is very relevant and needed. I have found that I have hit the limit point where I can rely on rules of thumb and I am now having to study a lots of maths that I should have already learned many years ago in order to learn all of the theory of electronics that I would like to know. Understanding a circuit topology includes understanding the maths that explains how the components interact. For example a switch mode power supply, you can build one with rules of thumb you can get controller chips off the shelf and follow the form and has already worked out for you, or you can have a thorough understanding of how each component in the circuit works and be capable of designing your own from scratch but you won't do that without maths.For most practical applications off-the-shelf switch mode power supply chips are just fine and so we can all get by by simply following the formula given on the datasheet which are a derivative of more complicated calculations that are simplified for the end user under certain circumstances. But as soon as you will need to design yourself something a bit peculiar and bespoke you will then find you are totally on your own and you will probably need a decent level of maths to work out your circuit.

content: Quote from: tggzzz on December 23, 2014, 03:42:27 pmBack before Christsmas I had PMs requesting that I show the error. Given the difficulty of formatting maths on this forum, it will be difficult, but I'll do my best.Firstly, as any fule knos, "i" represents current, so I'll use the traditional "j" to be sqrt(-1), and I'll use "w" instead of omega=2*pi*f. Secondly, this kind of manipulation can arise when doing frequency domain analysis of circuits, where term such as1/(R+jwL)are common. Thirdly, I'll note that MrFlibble's comment about using the Euler form is equivalent to using the complex conjugate described below.The key is recognising that a full representation of a complex number is a+jb, and that sqrt(-1) is a special case when a=0 and b=1.If we want to "get rid of the complex denominator" / "move the j to the top line" in1/(a+jb)we have to multiply top and bottom by the complex conjugate (a-jb).(1/(a+jb))*((a-jb)/(a-jb))Multiplying out the numerator and denominator gives(a-jb)/(a2-jab+jab+b2)or(a-jb)/(a2+b2)Now for the special case where a=0 and b=1, we can see that1/j=-j/1, and that's whysqrt(1/-1) != sqrt(1)/sqrt(-1)And that's why despite "the best maths being the maths you can use without reverting to deriving everything from first principles",you need to understand the first principlesso you don't violate them.I hope that's all legible

content: Quote from: tggzzz on December 31, 2014, 04:02:59 pmYou don't need to resort to anything so extensive. The simple fact is that the sqrt(1) is +/-1 so you could just putsqrt(1) = sqrt(1)therefore -1 = +1 as they are both the sqrt(1). Of course the convention is to take the positive root but the problem illustrates what goes wrong if you misapply this.You're essentially finding the root(s) of the quadratic x^2-1=0 and there are two roots and similarly for x^2+1=0. Doing this twice and choosing different roots each time is bound to lead to inconsistencies.

content: Quote from: tggzzz on December 31, 2014, 07:52:09 pmIt still seems to me to be a case of carelessness when taking roots, particularly of complex numbers.A similar case would be:(-1)*(-1) = 1sqrt((-1)*(-1)) = sqrt(1)sqrt(-1)*sqrt(-1) = sqrt(1)j*j = 1-1 = 1Perhaps I've never come across it as a real problem because in most analysis you tend to only take square roots of real results such as the modulus squared of the complex result to get the magnitude. I'm not sure under what circumstances it is necessary to take complex roots in circuit analysis. Such a + b(jw) analysis is generally used in linear analysis of circuits and having a root function would be nonlinear.

content: I think North American education dramatically misses out somewhere on teaching math to kids when they are young or something. I found that number of people (engineers, programmers, accountants) that are scared of math among North Americans are drastically higher than let's say among Indians, Chinese or those who get Soviet education or those who went to school in Europe. I must say they usually catch up when they go to university but they go through so much pain and fear never goes away. It is like they had this drastic experience of drowning in backyard pool when they were kids and even though they can swim now fear is always with them.Going back to reality vs mathematical abstraction - there is famous quote of Richard Freymann:"physics is to mathematics as sex is to masturbation"

content: Quote from: Rory on January 03, 2015, 12:32:16 amThe bottom line is that the so-called developed world brings its children up to be lazy. Asian children are probably being taught harder subjects at a younger age because they live in a competitive society that knows that it has to compete with the rest of the world so they do just that whilst America and Europe sits on their laurels and think they are perfect.Every time I see a schoolkid walking down the road I have to cringe. Why do we need to dress our schoolchildren in the UK up like future office workers. What is the matter with proper jobs? As soon as somebody gets a desk they think they are better than other people. In the UK we keep watering down our education standards to make it look like the children we are telling to take it easy can look better and better. Fact is any child brought up in Asia could probably knock the socks off of any UK child in adult life. Yes we have these buzzwords these days like teamwork, networking and interpersonal skills. These are all things which children would learn through play, oh yes of course they don't play any more they spend all day in front of a television or a videogame or bloddy Facebook! Because nobody likes to interact and now we have to teach children how to interact rather than maths apparently. The first step to being a good team player is knowing what you are damn well doing. You can have the greatest interpersonal skills on earth if you cannot do the job you are paid to do you are a pointless piece of shit. I sit opposite a guy at work who can talk for hours and get on great with anybody but when it comes to doing work or developing a new idea he's a hapless useless idiot.Everybody these days wants to get into sales because it easy doesn't really require any work just to gift of the gab. It is time we stopped putting our children and in fact anybody on a pedestal. Life is tough get on with it or get out particularly if you want to take on fields like engineering. After all there are always jobs the people who don't want to learn the skills we need and those jobs are as important as those of engineers as well.

At best they are proud that they are going back to making the pass level 50%, as opposed to the one for the last few years of 30% being a pass, or you just get bumped up if you are not even at that level. Not helped by an education department that cannot even provide little things like schoolbooks, teachers, schools............. But they do have a nice fancy new central office suite for the top levels, and all are driving department supplied luxury 4x4 vehicles.

content: Quote from: SeanB on January 03, 2015, 08:48:04 amThe problem with teachers in the UK is that they never actually left school and have never seen the real world I had to work in it and have no idea, I actually make a point of not bothering to pursue teachers on dating websites if they have down that they are a teacher I just pass over the profile. It is because of failed education systems which are run by politicians who want to outdo each other on how many children pass without upsetting the children that is why I have no faith in a school system and value much more people who learn because they have a passion for the subject and do it as a hobby. When schools and universities function as independent companies that need to be profitable how the hell can we have a proper education system when schools and universities will be competing to get students in so that they can stay afloat financially so the most successful education institution is the one that passes the most students. This is not a recipe for good qualifications. Education is supposed to be an investment not a profit making business. That is why we all pay into the education system because if we were to have a country full of educated and clever people we would have a thriving economy and a better chance of not being misled by our politicians. For the political class it is convenient that people are lazy and easily pleased with a qualification they have not earned because it means they have not been taught to evaluate things properly and will be easily blinded by said politicians.

The quality of teaching has dropped because their rates of pay have dropped, so most of the really good ones went back to industry and the subject matter has an ever increasing Occupational health and safety component.As course costs increase, enrolments drop so the lack of numbers see a large number of elective subjects taken out of the curriculum, making courses less enticingAdd to this the situation where increasing concern of litigation in companies sees less uptake of experienced non-qualified people requiring someone in-charge assuming responsibility for their work, versus young inexperienced (and malleable) qualified students will see a lot of hobbyists never moving out of there own lab
