The PCB for this project was designed in Kicad with drill sizes and trace widths optimized for a 1/32" flat end mill. The board you see in the photos was created with an Othermill, ancestor of the Bantam Tools PCB Milling Machine.

These files have only been tested with a milling machine and may require changes before before being sent to a PCB fab house for production.

Optional color

Since the PCB will play a major role in this keyboard's aesthetic, you may want to dress it up a bit. You could use paint to cover the top side in a custom color, but it's far easier to use adhesive vinyl.

I used Oracal 631 adhesive vinyl, which is repositionable and somewhat forgiving during application – similar to drawer liner or contact paper. Consider using Oracal 651 type if you want something more durable & permanent. Whichever type you choose, the following process should apply:

Cut a piece of vinyl significantly larger than the PCB – ~13cm x 8cm

Remove the adhesive backing and apply vinyl to topside of PCB

Turn the covered PCB over and use a sharp knife along the board edges to remove excess vinyl

Slice holes through the vinyl for each component lead & use cross-cuts for the larger openings (switch posts, standoffs, etc)
