[WIP] experimental Painter

The first prototype is ordered!

The idea is to make a sort of posterize module (as featured in the Panasonic MX30 and the likes of), but with a lot of control.
So I made a design with 5 layers, which are 5x comparators with width and strength controls.
They can share the same input (they are normalised per input), but can also have their own input (for experimental stuff)
The outputs are routed into a R2R ladder and through an amplifier.

The first proto will test if this works as intended.

The next proto ideas:

  • voltage control over all stages
  • separate outputs for each stage
  • sandwiched pcbs
  • sequenced comparator output (5 step 4017 + 4066 gate)
  • SMD & ADA4851 (instead of LM6172)

If you have any tips or feature ideas, let me know!

proto pcbs have arrived, looking fancy
