02Schematic & PCB

Moved to KiCad. Two boards: a control board with the pots and jacks, and a main board with the op-amps.

Probing the first batch of boards:

A small firmware-free project, but I still wrote a quick script to generate the panel legend:

from math import cos, sin, radians

def knob_ticks(cx, cy, r, n=11, start=-135, end=135):
    step = (end - start) / (n - 1)
    return [(cx + r * cos(radians(start + i * step)),
             cy + r * sin(radians(start + i * step))) for i in range(n)]
