Personal electronics tool kit

Question

What are the items you have in your personal electronics tool kit?

Answer 1

Most important tool:

• A quality soldering iron. Mine's a Weller. Those Radio Shack pencil irons are useless, and will only make life more difficult.
• A wet sponge for cleaning the iron tip, several tips for the iron.
• Both desoldering braid and a solder sucker.

• Plenty of 60/40 solder, the silver bearing stuff doesn't flow nearly as well. A well stocked junkbox is extremely important. The more components you have to hand, the faster you can work.

• A good digital multimeter, I love my Fluke. Add to that a good analog multimeter, digital meters offer no sense of change over time.

• A dual channel 100MHz oscilloscope (mine's a tektronix mainframe that I scavenged).
• Good lighting! A third-hand rig or similar to hold parts and boards that are being soldered.
• A spectrum analyzer is very useful for radio work.
• A function generator.
• A sharp pair of flush cutting nippers.
• Several spools of different coloured 20 gauge hookup wire.
• Some people keep flux to hand, but I've never found I needed it.
• Assorted scraps of printed circuit board, or strip board - breadboards are very finicky and can add circuit-killing parasitic capacitance.
• The absolute best tool I've found for cutting PCB is a jeweler's saw. You can buy them from Contenti, and aren't very expensive. I've never seen anything use produce a better or faster cut.

I think that covers the bulk of it, it may seem like a lot of stuff but it's mostly small stuff. An LCR meter is handy, too. I have a foredom flexshaft, it's kind of like a Dremel but more powerful and higher quality. They're not cheap machines, but are a real life saver for modifying circuit boards.

Answer 2

• Harbor Freight multimeter. They actually work quite well. RS has some slip-over test lead IC-hooks that work with the bundled test leads, totally worth the extra cost. More expensive meters are better, but these are accurate enough (esp. for digital work: is it high? is it low? it's cheaper than a logic probe!) and small enough to go in a small tackle/toolbox, and if something goes wrong it's easy to replace. The transistor tester (shown below) saved me when I picked up some 2N2222's at RS and discovered that the package had the pinout backwards. Seriously, even if you have a nicer meter, you will find uses for one of these.
• Lots of IC-hook wires. Those things are fantastic, and are great for probing and prototyping. You can never have too many of those. I prefer these over alligator clips.
• Small/jewelers screwdrivers.
• Wire stripper.
• Small needle-nose pliers.
• Analog o-scope that was a cast-off from school.
• RS soldering irons. Honestly though, it's not worth getting the RS. Get a good iron. And solder wick, not that silly solder sucker bulb thing. I think this is the area I regret the most in my toolkit. I've used the small pencil iron three times and I botched a board with it because it didn't get hot enough.
• Arudino + Protoshield. Nice, small little prototyping platform.
• 6500K desk lamp lighting. Really, the daylight color helps. Very bright.
• Plastic compartment boxes for holding parts.

Answer 3

1. 1k, 10k resistors, i rarely need other values, maybe 100s if I have LEDs.
2. caps, 4.7uF, 1000pF, .1uF
3. PICs, just some PICs, i think I have some pic16F876As, but I have access to three others also.
4. LEDS, a few cheap ~10mA LEDs
5. FLash memory, I never know when my project will need memory, I keep simple ATMEL memory, I can give a part number if wanted.
6. ft232R, never know when I want some USB connectivity.
7. I have other random parts, but they probably cycle pretty constantly.

I try to get a professor or my boss at work to buy my components, I do not tinker a large amount at home, but build little projects for my professor, or students in the class I help teach, to use, or I will build little projects to speed up a task at my job.

Answer 4

A couple of people have asked me about tools so I put together this list (below). I will put it on my site soon. If you think you may want to do SMD I would invest in a better iron than listed below (also a good light and a magnifier). My SMD tool recommendations are at http://tinyurl.com/5foeou

Answer 5

Tool wise I have: Multimeter, probe, pocket oscilloscope from seed studio, solder iron, screw drivers, and other various hand tools.

Bench wise I have: tektronix oscilloscope (from school), programmable power supply(from school), function generator

Component wise: Too many to list here. I am one of those people that stores love to see coming. I see something and think to myself "I might be able to use that later" and so I stock up in bulk. Or my neighbors throw out stuff and I take it and rip parts off it (my wife hates that). She thinks I could be on that show called "Hoarders" but for electronic components. Then I lucked out because my school upgraded their labs, and my professor gave me everything they had because the school was just going to throw them out!

Answer 6

I make sure I have a 1/8" stereo jack on a length of wire so I can plug my breadboard projects straight into my computers audio input. I also have some paperclips, that I normally use for bending into little brackets, that can hold various strange shaped components onto the breadboard, i.e little piezo buzzers or speakers. And last but not least, Blue Tac, I can't stress enough how many times it's helped me out in a tight spot, it's useful for all sorts, not to mention holding wires in place whilst soldering. I also have a lamp, it's an eco-friendly 2.5w super massive LED thingy. It's got a swan neck, it's really bright and at £20 from Ikea it's a darn site cheaper than a proper technicians desk lamp.

Jim.

Answer 7

Here are some of the tools I find myself using most often:

• Weller WES51 soldering iron
• Panavise Jr.
• Fluke 87V multimeter
• PHT-PYT-4 wire strippers (don't buy the cheap chinese knockoffs. Mine were unusable.)
• Rigol DS1052E oscilloscope (somewhat expensive, but even as a relative beginner it's been an invaluable learning tool for showing what's actually going on with the voltage levels inside a circuit.)
• Cooper Tools "Xcelite" 170M cutter
• Elexp 060210 long nose pliers (I find myself using these constantly. Best $2 I ever spent.)
• Soldapullt deluxe
• Scotch tape for holding components in whilst I'm soldering them on the underside of the board.

I use a 12V computer fan hooked up to my three output variable power supply to dissipate solder fumes. Seems to work fine for now.

Answer 8

• A pencil (and sharpener). Molten tin won't stick to the carbon of the pencil, so you can use it to open a solder pad or solder bridge. It is in the same category as desoldering braid and a solder sucker.
• I like to use one small and cheap breadboard for soldering. It holds pins nicely in place while I solder them. I use it only for soldering to prevent flux and resin from ending up on other components. Same category as a third-hand rig.
• Antistatic foam to keep IC's safe.
• A drawer full of old power supplies (SMPS, that came with telephones, monitors, network equipment, ... at various voltages and currents) saved from the junk yard.
• Order components in bulk: 10, 50, 100, 500+ pcs. prices can drop incredibly if you find the right shops.
• Couple universal heat sinks and mounting material.
• Pin headers, lots of them. I often push the pins out to reuse them by pushing them eg. into a breadboard (or female header on a breakout) so I can easily connect a multimeter to it.
• Lots of single pin 2.54mm Dupont male and female connector wires to make interconnections between male headers.
• Battery holders for 1 and 4 penlights.
• IC sockets.
