I have got 3 options in my head :(1) getting 33,000 count voltage meter ( 8.99$) and configure it to be switchable - 33V range and 330V range should be good enough )(2) getting good fluke 27 -FM (the yellow one ) for about 50~80$(3) maybe buying one more hp3478A ?( somewhere between 120$~150$(?) )I shall mention I already have :2100PCS resistor kit ( 1/4W )like 20 op07'ssignal transistor assortment kit ( the cheap 180 pcs one )and some junk box of courseI think of getting :100-1M 1turn pot 10 Value 100pcs trim pot kit - 9.79$ceramic cap 25 Value 20 each 500 Pcs -5.98$100X LM358-5.89$100X2n3906 ( already got 100pcs of the 2n222 ) -2.99$100X2n3904-2.99$Total cash =458$I think of saving the rest for future projects - what do you think ?and I think that's it .... what do you think ?thank you in advace

content: heythank you gibbled and daveI dont feel like I whant to eatch my own board yet , I like prototyping with bear wier and soldering boardI know I am "coverd" but when meassuring temp ... well you left with "only" two meter ... hence I thought about getting another one ...the goot is simple plug into the wall shit ,though I can struggle with it for now because I really whant to invest on things I really don't have .SMD hot air gun is good idea , but I don't have the need for it though .LCR meter will be good for any switching project and power supply maybe handy as well , I'll think about it - thank youas for microscope , nope , I thought about X8~10 diopter maggie lamp for soldering Job ( I still got good eyes )and for reading really small silk screen on small parts ... 25$ USB microscope (X200 ! ) will dowhat equipment shall I be looking for ?except from the two power supplies I cant see any other needed equipment - Am I wrong ?since I am not yet in micros etc , I dont need MSO or logic analizer yet ,ad per the other gear , spectrum analizer, network analizer and arbitry wavform gen, as well are not necesar, I guess - any other type of equipment ?thank you in advance

Put a restraint and wait abit longer until you are very confident by your own on what and why you have to buy something.

Why ak for advice if you just ignore it?I missed the function generator you already have. NO, you do nt need another multimeter yet, for a long time. An LCR meter would be much more useful than a new multimeter. USB logic analyzer would be a useful thing too. Electronic load? Maybe...

You can change a scope or scope easily, but the place where you work tends to be permanent once you've made the choice.

content: Quote from: eevblogfan on March 29, 2013, 01:58:28 pmWelcome.QuoteNice. True you want to save your pennies, and looks like you are. I do find myself using many of these (3M sells pretty cheap interlocking solderless boards fairly cheap). I also find those tiny ones with the sticky stuff on the back handy (e.g. to put down a voltage reg, filter caps, diode, power indicator, barrel jack), can use these for all kinds of little mini circuits you might find personally useful and it lets you plug and play with them using jumpers.QuoteExcellent work on the free cycling/reuse, keep it up!QuoteI find I can never have enough alligator and mini grabber jumpers, you'll get a feel for what you need as time goes by. I also find having lots of different colours really helps me keep what is what straight once I've got many (don't want to short out power by accident).QuoteShould be fine for most stuff, eventually you might end up wanting a more non-polar solvent as well (better at removing oily and waxy stuff). IPA acts marginally well as a non-polar solvent though. Pure ethanol (well it absorbs water so 95%) is a pretty good and safe (toxicity-wise) solvent that acts well as both a polar and nonpolar solvent, but can be hard to get (they think people will drink it to get drunk and avoid spending money on more expensive drinks)Most contact cleaning solvents are mixtures of IPA and higher order alcohols like butanol.QuoteEbay, search for: hemostat, haemostat, locking forceps, iirc sparkfun.com sells these.

content: I'd suggest dedicating some money toward having PCB fabricated. With vendors like Itead, Seeed, and OSHPark around, there is little reason to make your own boards any more, but it takes some change in attitude to start sending off cash for more boards than you need that might not work. (At least, I'm finding this true for myself. Frugality is all fine and good, but $100 or so spent on professionally manufactured boards is money well spent.)

timestamp: April 02, 2013, 02:19:32 pm
content: A quick look at the PM2813 and I can see that this only does 60 watts output; you should probably go for a better PSU, such as the Instek GPS-4303 (which I own and can vouch for its performance), the new Rigol DP832 (which I will own shortly and will be reviewing on here once I get it), or some other 2+ output PSU that can do at least 30V@3A=90W continuously.$200/pcs seems a tad too cheap for the Agilent 6632B considering Agilent's asking price of $2600. Are you sure it's not "for parts, not working"? This being said, this doesn't appear to be that great of a PSU apart from its high accuracy. Once again, I'd say go for the Rigol instead.The Fluke 87-V is a very good handheld multimeter, and $250 is a good price for it. As long as the low precision/accuracy and lack of features doesn't bother you (it's no benchtop DMM) than I'd say that's a good choice.Only you can decide what you need. Do you really need that many power supplies? Do you own an oscilloscope/waveform generator/LCR Meter/Frequency Counter...?

content: Quote from: olsenn on April 02, 2013, 02:19:32 pmAt least here in europe second hand market is full of Agilent/HP 6632B'seevblog user "KJDS" is selling them on ebay.co.uk for 120 GBP (apprx 180 usd) per piece and I haven't heard any negative experiences here.http://www.ebay.co.uk/itm/AGILENT-HP-6632B-Bench-DC-Power-Supply-0-20VOLT-5-AMP-Programmable-/350746462032?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item51aa1e4750I bought secondhand 6632B's locally here in Finland "by ton" and paid even less.I have checked dozens of these and all of them passed factory accuracy specifications. Only 1 unit was even close to exceed specifications and several dozens of them were passing calibration check with large margins.Note that 6632B is really handy as it can be also used as DC-load unlike 99,99% of other power supplies. Plus you can get full service manuals & schematics from Agilent in case something goes wrong. Now try that with RigolThere are some drawbacks also like: heavy, noisy and takes lots of space, especially if you have 8 of these.And front panel is not too robust, requires care during handling and transportation.

content: Can you please describe some of the projects you have planned for immediate future? I am talking about specific projects, not things like 'i want to build things'.It looks like you have too many of some tools, not enough of others. Lab equipment is there to be used, otherwise it's just expensive clutter.It doesn't sound like you've had a lab in the past, so consider getting cheap, used, un-fancy but solid things and focus on building up skills. No matter how great your lab is, you can't leave a pile of parts or a faulty PCB in the lab, then come back and find that your tools have done all the work.Hang on to your money, decide on a specific project, join a thread of people who are doing a similar project, start work on the project, and be reluctant to buy expensive tools until you are absolutely sure that the job will not get done reliably otherwise and that you will need the tool many times in the future.

content: Quote from: eevblogfan on April 03, 2013, 07:45:58 pmThis supply takes a substantial chunk out of your budget, and you pay a lot for the brand name. It's not worth it: get something simpler and cheaper, preferably a used item made by a good manufacturer, not a new Chinese item. Remember that while you are learning and experimenting, you will break things, and it hurts less to break cheap things. Electronics is an exciting thing, but electricity is ruthless and doesn't care how much you paid for your gear.Also you can search this forum for some very relevant and pragmatic advice on equipment, given by the user 'saturation'.Oh yes, in terms of books you might also consider Scherz's Practical Electronics for Inventors. Get the 3rd edition, as the other ones have many typos which a beginner may not catch straight away. The latest (3rd) edition looks better. This is a good and inexpensive book.

content: Quote from: eevblogfan on April 03, 2013, 08:26:47 pmThis was a reply to nctnico's post. You see, Art of Electronics is a well-known book, and a few generations of engineers were raised on it. Some people criticise it, but it is extremely hard to write a general text for a practically-minded electronics engineer. Electronics isn't like classics or philosophy, this isn't a subject that can be mastered from a book. Nonethless, I stand by HH and the huge amount of work they put into AoE. It is always easier to criticise than to propose constructive solutions, even imperfect ones.Quote from: eevblogfan on April 03, 2013, 08:26:47 pmI'd get 1x 6632B. Use it, see if you like it. Some do, some don't. If you like it, these aren't very rare, you'll get more as the need for them arises.By the way, where are you located?

It's in your interest to pay for shipping once, not to get power supplies from different places. These are heavy items, and the shipping expenses to Israel are not small and add up quickly.

My worry is that you'll be sitting there with 2 power supplies and no money with which to buy parts for an actual project. That would be pretty boring. But if you can get some more funds for parts in the future, then go for the power supplies.

content: Quote from: eevblogfan on April 04, 2013, 07:03:45 pmTry to scavenge what you'd need and build it.For example, either an old device's enclosure could be repurposed, or make one out of plywood or plastic sheet. Suitable transformers can be found in old gear that's broken or won't ever be used again (audio amplifiers, integrated audio receivers, TV's, VCR's, Uninterruptable Power Supplies, ... types of devices).Plenty of schematics running around (internet and books), and by building, you'll learn as you go as well as save on funds (parts you might smoke in the process are cheap vs. buying new equipment or buying every single part from a supplier). And if you get stuck, there's plenty of people here that would be willing to help you out.Just a thought anyway.

Definitely will stretch your parts funds as they come along, so well worth the effort.

Building and salvage are a couple of ways to do this, as is purchasing used gear or even DIY flux or cleaning products (straight IPA, or IPA + Xylene mix <80/20% mix respectively> for more stubborn deposits).

content: Quote from: eevblogfan on April 05, 2013, 11:13:33 am0-9 is less confusing (10 positions, but gives you the set value), so is preferable. For example, if you want 1 ohm, set it to 000001. If you want 17k, then 017000. Using the DIP's can get you the value, but reading it will be confusing. You'd either have to use "10" for zero, or shift everything (1 =0, 2 =1, and so on), as well as take additional care to be sure it's wired up properly for whatever method you decided on with those DIP switches.Here's a schematic by Tom Gootee.http://fullnet.com/~tomg/gooteedr.htm

content: I agree with westfw.If only you saw my 'tools' in Russia when I just started off playing with electronics.... You'd probably cry.What's between ears is a lot more important than a fancy lab. You already have all the tools needed, even more! What you need now is broken stuff, lots of it, to take apart for parts, or, if the dead item looks good, perhaps to work out what killed it and try to repair it.For example, when I was little I went to as many neighbours as I could and asked them to give me their broken stuff instead of throwing it out. After a while I was able to repair some of the dead stuff and took it back to the owner with thanks. And then I got even more dead stuff when people realised that it might be fixable and they'll get their item repaired free of charge. Besides, Russian culture looks with approval at people with repair skills, so you get respect, even when you are 12.With this approach one learns very fast, believe me.

content: Don't worry then. If your soldering skills are good, you can survive without a hot air station for a long time. As long as you don't need to work with BGAs, other stuff can be dealt with by a soldering iron.You said you already have things like tweezers, cutters, flux, solvents, copper wire, solder, etc.Other things that you either have or can get cheaply locally: good LED lamp, headband magnifier if you work with small components a lot.But this is small and obvious stuff.
