DIY STUFF

That sounds like a good plan! Things that I buy in packs of 100 at least:

resistors

  • 100k
  • 1k
  • 10k
  • 20k
  • 47k
  • 470k
  • 1M
  • 2k
  • 4.7k
  • 100
  • 220

(for resistors it’s almost always a good idea to buy at least 100, they are much cheaper per piece at that point in most places. By now I only buy less of a value if it’s a very rare value, like 49.9 ohms, or something like that)

capacitors

  • ceramic 100nF
  • ceramic 10nF
  • (ceramic 1nF?)
  • EL 10uF
  • EL 1uF
  • EL 100uF
  • EL 4.7uF

Enough big 4700uF for you power supplie(s), usually there are 6 needed for one power supply board. Make sure those have enough voltage rating (at least 25V, if I remember correctly)!

diodes

  • 1n4148
  • 1n4004
  • LEDs in the colors you like

transistors

  • 2n3904
  • 2n3906
  • maybe BC547?
  • maybe BC557?

connectors

  • 10 pin IDC sockets (whats the correct name?), you want shrouded, so you can not reverse the cable!

  • 16 pin IDC sockets (whats the correct name?)

  • pin headers 2.54mm in various lengths

  • pin sockets 2.54mm in various lengths (with most you can buy large ones and cut them to length)

  • ribbon cable (I would get 5m or 10m for a start)

  • jack sockets! many many jack sockets!!

  • maybe molex connectors, if you want to use this style of connecting and not mount the jack sockets on the PCB

potentiometers and switches

These are expensive, so depending on your budget you might want to keep those to a “minimum”. But in the end you always want to build more modules and you always need more, so maybe just buy a lot! :laughing: (but not so many that the places run out of them and no one else can build anymore, looking at you, Megadrone :grin: )

  • 100k

  • 10k

  • enough caps!

  • SPDT switches (on/on),maybe (on/off/on)

  • DPDT switches (on/on), maybe (on/off/on)

  • trimmers, 100k, 10k, 1k (not a 100, but 20, to 30 each is good to have, I would say)

opamps

  • tl072
  • tl074
  • maybe lm13700?? you do not need 100, but they are common, so maybe 10 for a start?
  • sockets!! not only for opamps, but for all you ICs, so buy several sizes!

regulators

  • LM7805
  • LM7812
  • LM7912

I probably forgot half of the stuff, but others could add! Can I make my post editable by everyone?
