content: Job hunting is by far most effectively done via networking. Networking, unfortunately, cannot be done easily over a short period of time.So if I were you, I would start with building up your network of social / professional contacts, going to conferences, etc.That's unlikely to yield any opportunities over the short term. For that, you may just have to do cold calls, resume submissions, head hunters, etc.Hope it helps.

Unusual phenomena, Bubbles on resistors.   - Page 1

content: Hello all.I recently acquired an old piece of test equipment and when disassembling it I discovered something very strange. At least to me, I've never see this before. When I opened the case I saw something glistening on the ends of some resistors connected to a selector switch. When I looked at the resistors with a magnifying glass I could see they were tiny glass like and very prismatic bubbles. I took a thin wire and touched one and it cracked like thin crystal. My first thought was that it was caused by overheating of he resistors but the resistors looked fine. Does anyone have any idea what these bubbles are?Sorry about the image quality.ThanksJohn

content: Carbon composition resistors that got hot, and the wax impregnation has melted slightly and formed bubbles with the gas of the lighter volatiles evaporating. Not a problem, it just is a property of the resistor that the wax will melt when hot, and this one had some lighter volatile parts and blew bubbles. Normally the wax is there to protect the carbon composition from moisture, and will soften with heat. It just says they were run at slightly above maximum power for a while, so they dumped the wax. You can also see that the colour bands have discoloured slightly from this, the nominal 22k 10% bands have gone slightly brown from the light toasting. If you are worried you really will just replace them with higher wattage units, likely 1W units.

But in my personal opinion allot better that McCAD, KiCAD and DipTrace on Mac.I say "on Mac" because the KiCAD/DipTrace Windows versions must be allot better given how many are flocking to it.

I have applied to DSTO, Aurecon, Alcoa and BP, and BP rejected me since they're all in Western Australia and maybe also because I didn't do so well last semester. Are there any other places that I can apply to? Maybe one that isn't listed in Engineers Australia website? A friend of mine got work experience at an optical/medical company but they are not opening to undergraduates this year. There's eLabtronics and they offer work experience all year round. From a few friends of mine though, it's more like a sweat shop so that's my last choice if I can.

content: Hi All,I am a Mechanical Engineer with several years of electronic packaging. I have been getting a lot of jobs lately to wrap an enclosure around an ECAD file. These jobs consist of 3D printed, machined, and sheet metal enclosures.I have set myself to accommodate these needs at a prototype level. I can do quick turn on iterations. I typically take a product through to production, but I am thinking of just specializing on the prototype design iterations. I think it will be good for the customer shorten the cycle time. It will be good for me since I will not have a lull between jobs (as is now).The idea behind it is for the customer to send an ECAD file. We design an enclosure based on your needs or specifications. We can do fit and function (EMI, thermal, shock, water/dust ingress). I have someone who can do industrial design if you need a certain form.Would you be interested in a service such as this? I have attached a flow chart to give you an idea on how this would work.Thanks in advance for feedback.Bill

The first came from University College London, and it is about designing an ultra low power wireless transceiver with an energy harvesting circuit as a power supply circuit, in standard CMOS technology. The second one came from Eindhoven University of technology, and it is about designing an op amp, together with an ADC, in TFT technology, as a front end for sensors.Now I am struggling with myselfbecause I really don't know what to choose between the two. Taking into account that the two topics are very interesting to me, which one in your opinion is the best if I want to continue my career as a researcher? which is the best if I want to go to work in companies after the PhD?I am sure there is someone with good experience in these things that can help me.PS: the scholarship in London is 16000£, while in Eindhoven is ~20000€Thank you very much for your help,Carmine

You do your grad courses, do research with your advisor, publish papers and eventually define the topic of your dissertation.Can you visit both and talk with relevant people? It may give you a hint which environment you prefer. Whatever you will do well be pretty narrow, it's more about the skills that you will acquire and the degree.

None have all the features mine does, and are usually about twice the price I'm askingI had planned to do this all open-source, but I realized that I'm directly competing with a company who is not at all ashamed of stealing other people's workOnce I get bluetooth ready, that'll be my killer feature. No one else has it, not even the big sleazy company. I'm pretty stoked right now, and I just wanted to share

content: In my project I need to transfer some heat ( about 50°C) from a plain( straight) metal heating element ( approximately 100mm x 200mm of size) to a glass of a similar size. The problem is that the glass need not be precisely straight and the heat is NOT transfered evenly. Is there any material (being between the heating element and the glass) that flattens the unevenness( between the heat element and the glass) so that the heat is transfered evenly?

This, the embedder does have control over. There are two style of embedding, the old one which is using a Flash object tag, and the new style, which is using an iframe, which leaves up to YouTube to load the appropriate video depending on the browser configuration. The forum software is currently using the old Flash video tags.The problem could be solved in the forum software by changing how YouTube videos are encoded into HTML. Any user can also solve this themselves by following the link under the embedded player and watching the video on YouTube, so you're not dependent on what the forum software is doing.

My favourite video isas I used to have directional cables I made sure were plugged in the right waySo, I'm modifying an old Toyota Spacia van to live and drive around Australia in. I have calculated that going around anti-clockwise is optimal because driving on the inside of the circumference of my island is approximately 10km shorter than going around the outside.Me and the dog do like our creature comforts, so I'm adding a solar panel, fridge, stereo and sundry items to make the trip even more enjoyable. Here is a picture of my dog:Needless to say, I am bringing along a dustbuster too!The reason for my post is that I've made a little plan for the electrics but I have a couple of questions I hope you guys can answer for me so I can get the most out of my investment. Here's the plan:I did this in TinyCAD and I hope you'll excuse the fact that this is not a proper diagram of any technical merit, just a basic plan to get all the bits straight in my head.You may note the leisure battery has four connections, the shunt (battery monitoring system), the solar charge controller's load, the parallel connection to the starting battery and the stereo amps. I am wondering what is the best practice for making these connections safely. Should I fuse each connection individually or should I put one big fuse in to cover the whole lot?You might also see that there is no provision for charging the system from 240V AC. I'd like to add this in. I have a Wan Hung Low 13.8V 20A power supply. Could I repurpose this as a charger/supply for the system when I have access to shore power? I found this thread:http://www.physicsforums.com/showthread.php?t=525162on the subject but I'd like to get your input (no pun intended) on the matter as well.Looking forward to reading your responses!Matt.

There was also a keypad cover (much easier to find, but rarely cheap) that would keep the keys clean.The upshot to the 41, of course is that you can get the Machine pac for it (I have one) which has all sorts of useful stuff in it. Cams, four-bar linkage, physical parameters of a slider crank, gear forces, etc. Anything it didn't have, you could easily program it to do, and best of all, you can re-define the keyboard so all of your favorite functions or personal programs are assigned to whichever key you like. If you were careful with your program design, you could easily get them all to work together. In the case of the 41CX, it had a programmable assign function to allow you to automate keyboard configurations.It was also originally built in the 70's.Personally, I would be no mood ever to bring my 41's into a harsh environment.If youreallywant to spend some money, there was an outdoor enclosure for the HP-71b, which could be made 41 compatible with an emulator module.For sure easier solutions than that though, including rolling your own out of RasPi or something.
