content: If you were starting a new fully-operational lab and had a $5000 budget what T&M equipment would you buy?The rules of this challenge are the same as the$200 workbench challenge. In particular, you may only use new, regularly-stocked and non-discontinued/EOL pieces:QuoteEdit: You can use used equipment if you can quote an accurate fair market value and it is in good repair and it can be readily purchased from the Internet and it is less than 10 years old. You can also use kits, such as the $20 LCR ESR transistor checker meter.Also presume no prior lab equipment. Furthermore the $5k budget would be just for lab equipment, it would exclude things likes supplies, parts, consumables, and standard shop tools. Extra points go to solutions that are small and compact in space, ideally everything should fit on a single workbench or be stowable in a typical closet... none of this room full of gear nonsense.

content: Also ruling out second hand gear is not very wise. $5000 doesn't buy you a lab with decent new gear. If you'd have $500 to spend the choices would be easier. $5000 is in a league where you want professional grade equipment and that is also where there is a huge empty gap between low cost Chinese equipment and decent stuff from the A brands.

content: AnNI Virtual Benchinstrument might fit what you're doing nicely, especially if compactness is a high priority. Shahriar did a good teardown and reviewhere.That'd cover most of a basic bench, the remaining cash I'd put into a couple of general purpose multimeters (something like a Fluke 115), maybe an LCR meter, an electronic load, a higher power/voltage lab PSU if needed, cables etc.

Presume you have a full workbench to work with plus a shelf above and below the workbench and a closet to store unused gear. I put that clause in there largely to prevent people from filling up the entire room with equipment.

I bought my scope for 600 EUR, the closest current equivalent costs when new around 1300 EUR. Multimeter? New: 600 EUR, old 200 EUR. All in all, you can get the same specs for 1/10 of the price if you scour ebay, local ham fests etc.

content: Another way to put it might be:You're new at work. New dev team, project something or other. Boss needs a list of equipment to buy (or you, being new, need some ideas of what equipment to get, and learn to use!), given ballpark budget and little more room than your cubicle or a common lab area.I'd say, minimum 200MHz 4 channel scope, with options if you like (anything from LA to spec and TG). Rigol's not bad but I'd suggest a higher brand, or good old fashioned name brand (Keysight/Tek). Biggest expense, choose accordingly.Power supplies and meters are next. I'd guess a triple output, 100W unit would be a good start, any will do (say, Rigol and up?). Personally I'd go with a good old fashioned analog type, instead of all those fucky digital interfaces. But I don't know if anyone even makes them new anymore. Meters, any good enough brand, up to or including Fluke.A signal generator is a good idea too. Probably any will do (Rigol and up?). I've never needed an arb gen, though I suppose they all are these days. Make sure it has the frequency performance (including square wave risetime and flatness) and voltage range you need.Additional hardware depending on project specifics (high frequency, RF, high power, EMC...), and ongoing additions understood as part of subsequent project budgets, or capital expenses.Don't forget general tools, pliers, cutters, measurement and cutting, material resources (protoboards, mech and elec stock, hardware), components and so on. Most components can be budgeted for within the project as expenses, just make sure to get extra to hang onto for the future. (If you have a direct customer for the project, make it understood that that's part of the cost.) If you have a pedantic in-house inventory system, try your best to isolate your process from them. Don't even take deliveries at the receiving dock if you have to. Make sure your boss understands this: if it's not adding value to your project, you don't want it.Tim

content: You can't just guess what equipment you need for a 5K lab like you can on a $200 one. With a $200 bench, it easy as was a very limited budget, but also for a beginner getting started into basic electronics. 5k is a whole another league and usually goes way over for decent preforming equipment. So really depends on what you are trying to accomplish with the lab and area of research. Just for Spectrum Analyzer, could kill your budget. Then you may need a LCR meter's, a decent scope but would need to know bandwidth needed and they can cost 10k plus even to get one with low now noise, high BW, hardware FFT and ETC. Separate logic analyzer. Then you may need a electronic load and good programmable power supply, or a variable isolation transformer, or a good precision signal generator with low distortion, or a good frequency counter with 10, or 12 digits of frequency resolution and a good one cost money. You may need a good bench meter for data logging could be 6 1/2, or better which will cost money, or a 5 1/2 meter, or don't need a bench meter at all and go with a handheld, you will most likely need a very good solder station especially if your dealing with SMD components as need good thermal recovery and ETC. Did not even get into the specialty tools yet, or calibration, or reference equipment that maybe needed.5k is could be enough to have decent lab, but solely depend on what you need, if your willing to wait and buy used some equipment. We need to know is what your looking to design, or research and B/W and resolution needed, this affects price widely. Then can better determine and give you a good recommendation on what T&M equipment would be best suited for your needs. You can't just guess, as you find most of the stuff you would have bought will end up being dust collectors, or a paper weight and then realize you needed something else and now don't have it, as you blew your budget. You best bet is buy what you need now and then slowly buy equipment as you see needed.I would start by buying the basics like good reasonable quality solder station, doesn't have to be the $500 plus one, but can get for example a Hakko FX888D-23BY that will cost around $100 buck and will do the job in most cases, a decent hot air rework station is also a good investment, as will be needed down the road. Then would look into a decent tripe output programmable power supply like a Rigol DP832, which will cost around $400 bucks, others will cost around the same as well for a decent one, unless you get lucky and score one on eBay cheap. Reason why I won't complete dismiss used gear completely, I won't buy anything to old, as can be a hassle with repairing it. You will need a multimeter like a fluke 87v, or 289, or a Brymen BM869 , so expect to spend another $250 to $400 on one meter alone and you will need two. So will be around $500 to $800 on decent meters. A decent bench meter will cost you around $600, you may get lucky if you willing to wait and score a good working one for $300, or less, that for one. I could tell you a few good scopes and signal generators and ETC, but that where it really based on your needs at that point.I also hoping you have a suitable bench to work on already, as that a whole another cost and can easily set you back over 1k alone, unless you built one then can shave some cost off.

For 5K you need to be very specific about what you want to do.QuoteAnd if you buy the Spectrum Analyzer it might turn out you really needed a $3K thermal imager, or a bigger microscope, or ... something else.$2k will easily get you the basics of a decent lab (scope, multimeter, power supply, solder station...) Keep the rest for when you figure out what the hell it is you actually want to do in there.

content: I went the route you are going, minus the obvious mistakes you are about to make unless you change your approach:I bought used gear when possible, it is absolutely moronic not to. I cannot stress this enough, no matter your budget ($20-$200,000).... The only exception is the scope, which you may consider getting new (e.g., Rigol+hack) unless you think you may need >300 MHzI didn't set an initial budget, it just grew as I found great deals on equipment that I thought I could use (up to a perhaps not so reasonable point, but possibly <$5,000)Now I have lots of top notch calibrated equipment in excellent condition and still can't figure out what to use it (all) for?The most complicated thing I've built is a high precision resistor divider to help with calibration.

You can get them for around $500 bucks. A scope not a replacement for a good frequency counter. That Signal Hound USB-SA44B is pricey for a Software Defined Receiver (SDR).

From here on out the rest of your gear will be ether low-low end stuff or just low end stuff.And one more thing....Unless you Really-Really-Really, For Sure Need the precision, build your own bench power supplies, if you have the skill. I have worked places where they did exactly that until they got on their feet and could afford store bought supplies.The other thing I don't see mentioned here; what about all those cables?You going to buy them or make them. I prefer to make them since I am very good at it and know my workmanship is good to well beyond UHF by a decade or so.If the challenge was 10K or even 7.5K it would be quite a bit easier, especially not knowing what the lab is going to be used for.

content: QuoteIn the real world this would be an excellent question... However, I suspect that for some people the lab 'is' the hobby.There does seem to be a bit of a herd mentality to all this... I get the impression that some people want a lab because it's seen as cool to have a decent lab? So maybe there are no immediate plans to make use of the gear for any particular task?However, I would always recommend that you should only buy what you need but maybe I'm old and out of touch. It's certainly a lot different today with so much choice for decent used gear from the top brands at very low prices. If I was starting out again and someone gave me $5000 I think I'd spend it very differently to all the suggestions so far but then my interests are mainly RF and I prefer to buy used gear

content: When I got back into electronics around this time last year, the first thing I bought was an oscilloscope. Because I spent 4 hours trying to track down some problem that turned out to be that I'd messed up clocking the PIC. The only way I had to verify that was with some hacky toggling of an I/O pin to generate a frequency within the range of the frequency counter on my ancient multimeter and then doing some math.The second thing I bought was a BM257S, because I didn't trust my ancient multimeter and it was annoying me. Plus one multimeter is not enough.The third thing I bought was a DP832, because I was pissed off messing around with wall warts and generally fudging things. I actually did start building my own bench PSU, but the last straw came when I caught myself thinking that testing the various parts of the PSU would be easier if I had an adjustable PSU. If I'm honest I kind of regret getting the DP832, but only insofar as I should have got something cheaper. I like the DP832 and use it a lot so I don't feel like it was a waste.The fourth thing I bought was a new soldering iron, because my old butane iron was pissing me off.The fifth thing I bought was a FY3224S cheap ass function generator, because I didn't need one much but every now and then I'd find myself wishing I had one.There's been a few things that I got just because I wanted them, and there's a list as long as my arm of things I'd like to have just to play around with but don't really need and can't justify buying. But the vast majority of my purchases this year were driven by me doing something and then getting pissed off at not having the right tools.If I had $5000 to spend on test gear I think the only thing I'd have done differently is get a really cheap power supply instead of the DP832 and then build extra ones myself. Maybe a better function generator too. The left over cash would get put aside for covering components and future things that piss me off.

content: Quote from: G0HZU on November 05, 2015, 11:53:42 pmWe (I) don't plan to buy everything at once, I am simply trying to map out a budget so that I don't end up spending $20k on twenty oscilloscopes and a room full of redundant gear. I haven't even thought about what I want to build yet, there is no point in doing that until I have a lab with all the essentials. For me personally, I'm interested in computer electronics, but I'm equally fascinated by RF and analog... so I see little point in trying to specialize, I would like a general purpose lab that is designed for a maker (making is fundamentally R&D work).

content: Quote from: AF6LJ on November 05, 2015, 11:48:08 pmUntil quite recently I often questioned why you'd ever need a 6.5 digit DMM having spent the past 98% of my life without one, living perfectly well with 3 3/4 digits for many years thank you very much. For me it's not for absolute measurement, but for relative measurement: I do a fair amount of rework, and tracing down shorts, and badly behaving parts in circuit on a PCB is so easy with a high resolution DMM, and now I'd get frustrated without the resolution. But I'd agree, for absolute measurement the value of 6.5 digits still eludes me in a practical sense. I would not buy a 6.5 digit DMM new, or calibrated, there is just no value to me to be able to measure absolutely. The same is not true in the frequency domain though!I'd agree about an SA. They're the most under utilised pieces of equipment in my lab, and I just made a count and have five of them, from 1.5GHz to 22GHz. The two VNAs I have get quite a bit more use than the SAs.As well as the scope, get some decent tools especially soldering irons. I use four different irons almost daily for SMD rework, three Wellers (two 80W with different sized tips and a tweezer) and one bargain basement hot air iron from eBay which I'd have no hesitation in buying again. Well within three minutes on a rework job on a chip I'll use all four, and sometimes on the tweezer and hot air iron I'll swap bits.If the OP must get an SA, what about a Tek MDO3014 and liberating its bandwidth (and everything else)?I agree about cables, I have always made my own as a general rule... but they often do look pretty useless on a TDR compared to the professionally made high end brands like HP/Agilent Radiall etc., and for the VNAs above 100MHz or so I use the real thing for measuring stuff, no point in introducing more unknowns than you need to.Buying everything at once as if that's it, there will be no more, doesn't sound right though. I didn't know I needed a 20GHz oscilloscope until a few months ago. Come to think of it, I probably still don't really need one, but being able to squeak at 10ps/div sure makes me feel good. Somebody call the doctor.

"I haven't even thought about what I want to build yet, there is no point in doing that until I have a lab with all the essentials"And you are hoping with this approach you wont a) spend $20K and b) not be stuck with a bunch of equipment you don't need. I must be in bizarro worldI purchase equipment as I find a compelling need for it, not to dream up something to do because I have a piece of equipment laying dormant that requires that specific project to justify its existence in my lab...My first post still stands and now is confirmed by your post above, imho the initiation of this thread is the old cart before the horse... but good luck with it. I'm guessing your background isn't as an EE?Oh and just because Dave claims you could set up a decent lab for $5k doesn't make it so. Opinions of what is needed in a lab is driven by our own idea of what WE need for what WE are doing/interested in.Of course if your goal is to have a 'neat lab' then I'm sure there will be a lot of suggestions of what to get even without knowing what you are going to use it forcheers,george.

content: Quote from: nbritton on November 06, 2015, 12:33:18 amA four channel 100MHz scope with proper serial decoding options, a 30V 2A power supply and a >4.5 digits DMM are a good start besides a good soldering iron (be sure it allows to changes tips quickly) and a cheap hot-air station. From there you buy as needed. I'm still doing that but I also keep looking for good bargains as well. A couple of months ago someone on this forum wrote he wanted to get rid of a HP DC load; the price was right so I got it. I didn't really needed it at that time but in the past couple of days it has proven to be a good buy. For upcoming projects I look on Ebay for reasonably priced equipment which could be useful.

content: Quote from: nbritton on November 06, 2015, 12:33:18 amYou can build and explore a huge part of the electronics world with just a multimeter, soldering iron, and some basic hand tools. Only then will it be possible to understand what you need or want to do. Just using test equipment requires a good understanding of the underlying electrical characteristics and problem solving skills as to what to use them for.You don't buy all the equipment up front to start a band, first you learn how to play some instruments.

There is a seller who sells calibration "things" and he use one to calibrate them. There might be a market for this type of service vs a real lab calibration. Try posting an ad on Craig's List to see if there is an interest in this? You get a lab cal on yours and test other equipment w/o the cert for 1/4 the price.

content: That Rigol MSO4014 is a bad choice. That was the one I had issues with twice in a row and return it, as had suspected overheating issues and locks up as a result cooling fans rev to a 100%. First one channel when out completely and would come back at random. I do tend to use it for hours at a time and kept it power on when needed, so no offset, but still sure not have had issues within a week. Then when using the math functions, turning off the source channels also turns off the math function. The delayed sweep causes very strange behavior and would sometimes lock up. when attempting to display the trailing end of a burst of pulses. Turning on the delayed sweep causes the trigger point to randomly vary and it gets worse when the trigger mode is changed from auto to normal. Just a few of the bugs, their more, this was on both, so not just that I had a defective one, as order second one from different vendor.I agree with the above post get a Rigol 1054Z and hack it, friend has one and claims it good.

I think it was a steal at that price, a comparable Keysight would have cost $13k. If you notice everything I bought was on sale. For instance, that Radio Shack clamp on meter that I picked up for $13 normally costs $60, it was on clearance. And the soldering iron gets the job done when using good quality Kester 0.020" and a Hakko 599B-02 tip cleaner.

It is much better than modern Chinese built stuff. The exception being the scope (because of size and features). I wished I had a TEK 465I like Wavetek function gens. HP also has some nice PS (I do not know models), the member TIN restores real high end equipment.

Fast forward a few decades to today and I'd argue that something like the Rigol 1054 would be good enough for most people who want to do typical design work with MCUs and a bit of analoue design. It's probably better than any scope I have here and I'm certainly no beginnerObviously, if you want to do some fast digital design then you would want something faster than the little Rigol. The same applies if you want to join the 'pulse risetime' club

Brymen meter 289, or Fluke 87V, or a Fluke 289. You will need 2 meters and won't cut cost in this area. If you dealing with low current then you can go with a Mastech MS8218, or a UNI-T meter.7. BK Precision Model 1823A frequency counter8. DE-5000 Handheld LCR Meter8. General purpose active differential probe, like B&K Precision PR609.

content: I have a few comments, without the criticisms.Since it appears as you are new to electronics, here are the basics:. Dave explains what and why. His advice is very much still relevant. Evaluate what you need and separate from what you want. Use Dave's suggestions as a template and substitute equipment (some of the recommendations are pretty old). I wrestled with the same questions when I was purchasing test gear for my workbench -- whether to buy once and cry once, or buy cheap and buy often. I chose the middle path.Quote from: nbritton on November 06, 2015, 01:15:59 amPersonally, I wouldn't purchase a higher end Rigol/Siglent. I would send the scope back. They might be unbeatable on the lower end of the spectrum, but the value rapidly diminishes as you spend more money.For another $1k you can get a 4-channel 100MHz Tektronix MDO3014. Right now there is a promotion where you get the 3GHz spectrum analyzer option and embedded bundle. You can upgrade to 200MHz for ~$700 later, or if you aren't concerned with warranty, you can hack it and now you have a 500MHz scope + 25Mhz arbitrary waveform generator, and 16b channel logic analyzer (you will still need to buy the expensive probes).That being said, I would recommend you get a way cheaper scope or MSO. I started with a 50MHz Rigol scope until I could justify buying a "better" scope. I now appreciate it. My new scope doesn't sound like a diesel engine or flicker like a lightning storm having sex with a discotech.QuoteIf you want to spend money, I'd suggest to buy a better DMM or two, like a Fluke 87/289 and forget about a 6.5 digit bench meter. I bought a $20 ESR meter and it was worthless. I ended up purchasing a BK LCR meter.QuoteUnless you are fixing air conditioners or doing maintenance, I can't really understand why you would have a clamp on meter. So far, I've never run into a situation where I needed or wanted a clamp on meter.QuoteThink about getting a good soldering station, and possibly a hot air station for smd. Again, watch Dave's video and spread the money around focusing on getting the biggest bang for your money.Don't forget about cables, adapters, debugging pods, parts, etching supplies, copper clad board, drills, drill bits, solderless bread board, wires, orders to board houses, more parts, books, enclosures, development boards... you will spend eventually spend all your money, trust me. The list is endless...

content: Quote from: MadTux on November 06, 2015, 02:55:28 am+1 Ok, if you're feeling a bit spendy you can get a 1054Z, but dropping 25 Benjamins is a bit much for one's first scope. You can always get the MSO4014 later down the line when you need/want one, it's not like you're gonna throw out the 1054Z when you upgrade.Repairing stuff is great value for money, not to mention immensely educational. I find it helps motivate you as a hobbyist, because there's nothing like bringing a piece of equipment back to life. It also keeps you busy until your next big 'score'. Even if you have to write something off for being beyond economic repair, you'll have often bought something for less than BOM cost, leaving you with heaps of parts/spares to tinker with.Just go with the usual recommendations for basic gear, if I were to start over only buying new stuff I'd get a Rigol 1054Z, DP832 supply (a bit of a luxury), Hakko FX-888, one solid meter like the Brymen BM257 and a cheaper ~$50 one. Since you have a reliable base to start with, you can then look into buying used specialised gear as required after that, the 3.7k left over will go quite a ways.I'd recommend you return the MSO4014, downsize to a cheap analog scope or 1054Z and then just start building stuff (probably starting with the power supplies). The gear will come naturally as you go along, I promise. Hell, pick up that PS4 and projector to keep you busy for a few days until any newly purchased gear arrives whenever you hit a roadblock, it's a much smarter purchase than buying a bunch of gear you can't find a use for.

I can see them being switched on once or twice, and then what? Equally a VNA is of no value to someone tinkering with Arduinos. If you're reasonably into RF, then yes, there is some value to an SA, but in that case I'd go for a VNA before an SA. Even then, I guarantee it'll still be collecting dust most of the time. I think a lot of people buy SAs thinking they'll use them for finding interesting things in the RF spectrum. Well they're generally fairly deaf by RF standards, and have very limited demodulation options if any. You'd be a lot better off with an SDR, and in an lot of cases you can use an SDR to do things you might traditionally use an SA for, and they're a lot cheaper..

content: These funds would be better spent on education. Items like books, learning materials and related parts, classes and fixing older test gear is a GREAT way to learn. Taking on simply projects that are lab useful like making power supply from scratch as a start gives experience with how to design, build, making it function and fully understanding how to test and understand the design's limitations are extremely valuable lessons that are far more valuable than bench of shiny new test gear.IMO, it is a serious mistake to simply dump all those funds into new test gear without a full understanding of how they work, how to get the very best an most out of them and all the related details of making accurate useful measurements and properly utilizing the data created.Keep in mind, many of the great achievements in science and technology were done with rather basic instrumentation. When the required instrumentation or experimental device was not available, it was designed, built and made to fit the needs of the task required. Get to a place where this is achievable, focus less on the colorful techno widgets as they can be distractions to effective results.BerniceQuote from: nbritton on November 06, 2015, 02:07:55 am

Nice Swiss made pliers and cutters, Snap-On screw drivers that matched the hardware I was going to be using them on, super nice tweezers the whole nine yards in a tackle sized tin box. There was $800.00 worth of hand tools in that box. It ruined me...When I went to work in two way radio, the Snap-On Man got a cut of every one of my paychecks.

content: I am also in the process of starting a lab for projects but at the 2k level through a grant. I posted another thread a bit ago to get some ideas which was really helpful. My preliminary list consists of:Rigol DS1054Z ScopeRigol DP832 Power supplySiglent SDG1025 Function GenKeysight U1272A DMMAyoue Rework StationI have a digital Velleman VTSSC70AU soldering iron, not Hakko but seems to work pretty well.I have thought about getting a used HP/Agilent Bench meter.My big question is what kind of cables and adapters are the most helpful. I am just starting as an ECE student so its hard to know what exactly ill need.My thoughts are some Banana to mini grabber, Banana to BNC, BNC-BNC. I already have plenty of alligator leads and breadboard stuff. Should I get some mini/micro grabbers or other? What cables do you use the most often?

content: Regarding cables: I have a bunch of 4mm banana cables (Hirschmann with silicone rubber) and BNC cables with thin RG316 coax. The BNC cables are cheap from Ebay and I also cut many of them to solder them directly to circuits. Furthermore I keep a healthy stock of 4mm banana binding posts and panel jacks for connecting things together.

content: $2600 scope for a newbie just starting out? I personally think it's a waste of money. You could have bought a $100 analog scope on eBay if you're just starting out.... milk it, learn from it, study it, squeeze it for what it's worth, and if your project/skills demand more features/performance, then that's when you get say a starter DSO Rigol DS1054Z... again milk it for what it's worth, and you'll know when you need to "upgrade" to a bigger and better scope.Buying new test equipment won't make you learn electronics through osmosis by the smell of new equipment.Let's see, I was sophomore in High School and only had ananalog VOM (a kit I built myself), cutter, pliers, philips and flat head, and some drill bits and ferric chloride. -- from these primitive tools, I've built a power supply, a regulated power supply, a phono preamp, stereo preamp, stereo amplifier, crossover, AM radio, FM radio, digital clock, "knight rider" running lights, etc... I made my own PCB using a xerox machine, tracing paper, nail used as a punch, and a hammer and some permanent marker pens. The thought of buying a scope, or a signal generator didn't even enter my mind.You don't need $5K of new equipment in your lab before you can start learning electronics!Edit: Oops, forgot another tool... a 30W soldering iron that keeps getting hotter and hotter until you can't hold the handle anymore, so once in a while you need to unplug it from the wall.

I bet you guys have been tossing all kinds of stuff in carts, full lab setups like people sometimes buy at once totaling thousands and thousands of dollars, and then never buying any of it. Someone is monitoring that and losing their mind right now.

content: Quote from: fivefish on November 08, 2015, 10:38:22 pmHah, my first soldering iron was like that. Found it at a flea market when I was a kid and bought it because I had seen several movies where a tech would use a soldering iron (at least I think it was supposed to be a soldering iron) on a malfunctioning piece of equipment and sparks would fly off and then the equipment would start working again. Came with instructions in some other language that had one line of bad english that said something like "plug in, wait hot". So I would plug it in, wait 10 - 15 minutes until the handle was almost to warm to pick up, solder 1 or 2 joints and then unplug and let cool. Seriously had no idea what I was doing (edit: not suggesting that I have any idea what I'm doing these days).

content: Quote from: fivefish on November 08, 2015, 10:38:22 pmI not going to comment anymore on this thread as a waste of time, but this guy clearly has money to throw away. To make matters worst he bought two scopes not just one a MSO4014 and MSO2072A and why? Only he knows, as assuming for bragging rights? Well it's his money and if he want to spend like a fool, that on him.What kills me is he even complaints about over paying for a multimeter claiming he see no difference between a $70 to a $400 meter wondering why spend the extra? This is coming from a guy that just getting into electronics that just brought two expensive DSO's, which are not even that great. At least that thread worth it for entertainment value, which more likely will be derailed very soon.https://www.eevblog.com/forum/testgear/tektronix-mdo3014-vs-rigol-mso4014/60/

content: This thread does have someaspects, but mostly its just a giantI wouldn't buy ANYTHING until you need it for an actual project. Taking equipment advise from random (well meaning I'm sure) people on the internet and spending money on random gear you will most likely NEVER use is just crazyGrow your lab empirically! After a few years you'll end up with a lab full of equipment that is useful to you for your projects rather than a bunch of useless crap you've never used. Spending money on random gear could prevent you from even starting the first project if, for example, you need a fancy jtag device programmer but spent the money on an AC clamp meterFYI the first piece of equipment I turn on in the morning, and the last thing I turn off at night, is the espresso machine.

content: I did try that once, well, to see how much I could drink alcohol-wise before I was a worthless lump when placing parts, on even a small run it's a boring task doing this by hand, at least you should be able to enjoy yourself, right? One glass of wine didn't make any noticeable difference. Two, and I might as well sit on the sofa and watch the TV instead, the difference in dexterity and concentration was startling. It was an experiment not worth repeating.

My lab is in the $200 category and I'll have to manage with Lagavulin. Sure, it cuts into the DMM/DSO budget, but you can't realistically think working with empty Glencairn.(I lied a bit about my lab, I've 87V + DS1054Z + FX888D and I think it's a great starting point for a beginners lab.)

content: I just built my lab (some of you may have seen the thread) and in total it ended up close to that amount. Though, at least $1000 of that was to build the actual lab desks and static matting and things you may have already. There isa thread on it here, though some changes were made to the list on the first image. Furthermore I spent around $500 on the first project (my take on the word clock project, with 28x28cm PCB and laser cut aluminium front plate). I think including a first project to get the lab set up is a good thing to do.If I did not have to spend money on desk and anti static matting etc I would've gotten a spectrum analyzer for that last $1k, and in retrospect I'd go for a MSO. Having the LA on the same unit as Osc makes so much sense. I get by with the separate one but it's those small things you learn along the way I guess...
