We're just getting started with version 1.0 now, but this is where you will find links to purchase kits and assembled boards. Meanwhile if you want to support the project, check out the links in the "Support The Project" section below.

This page is for the core of the system, the switches for the keys or "SwitchBoard". Depending on how big a keyboard you want to build, the parts list per octave follows.

  • Switchboard (2 per "Octave")*
  • Spacers (Assuming the standard bricklaying pattern, first level gets half spacers on ends with full spacers between, second level is all full spacers, third level repeats first. Also I used 3 small spacrs per black key to raise them up above white keys)
  • Keys (8 white keys per "Octave" and 8 reversable black keys per "Octave")*
  • Switches - I used 4.3 mm tall 6x6 mm tactile switchs for the white keys and 9.5 mm (just barely cleared) 6x6 mm tactile switches for the black keys.
  • Bolts - I used 2 each m3x10 bolts for each white key and 2 each m3x15 for the black keys
  • Headers - The main interface header is a 2x5 header with 2.54 mm pitch. You'll need two per octave and two more per octave for any module connected directly to the switchboard
* Each switchboard is actually 8 keys, whereas a full octave has 14 possible keys**. That means one extra white and one extra black per octave here.

** This system was designed to allow multiple configurations whether you start with "A" or "C" or some other natural key.

At that point, assuming you've tested for functionality with the light test module, you've gotten as far as I have. Time to start developing sound generation modules.
