1k reverse audio pot alternative
« on: January 25, 2020, 10:57:27 AM »
Upon building the Woodstork, a 9mm, right angle PC mount pot with plastic shaft seems to be unobtainable.  The regular 1ck shaft pot is too thick  for a flush mount.  I would use a 1k audio taper and wire it backwards, to get fuzz on the ccw end of the rotation but smallbear doesn't have these (1ka)..  Aside from putting this in a larger inclosure and using non pcb mounted pots, what other options do I have?

Have any other values like a 2k or 5k?

You can change the taper of a linear pot to audio or revise audio by putting a resistor with 1/5 the resistance of your pot across pins 2 and 3 or 1 and 2, depending on your circuit.  You have to determine which leg of the pot on the hot side and then decide from there. Here's a link that explains in more detail.

100k is the lowest reverse audio...5k, the lowest audio for this type pot

A5k wires backwards will work, throw 5k resistor on it.
