Smash Drive Parts list
  • [1] Any value from 1 – 10k works here. This is a current limiting resistor for the LED. smaller values make the LED brighter.
  • [2] If you can’t find a 500r pot you can use a 1k instead.
  • [3] Get a socket for this. Always a good idea in case something goes wrong and you need to replace this.
  • [4] This will fit in almost any enclosure, I planned the PCB to fit a 1590B, but you could use anything you have on hand.

I used 9mm pots when I designed the board. After ordering the boards I realized I couldn’t source a 500r pot from Tayda. If you have problems sourcing this value you can use 1K pot and bridge legs 1 and 3 with a 1K resistor. This worked for me. See the images below.
