This is the DIY Kit of the OKAY 2 Synth. It comes in two varieties:

  • BYOP (Bring Your Own Printer): Just the PCBs and electronics components. You'll need to print the 3D models yourself.
  • Complete: Everything included, no 3D-printing required. Just solder the PCBs and assemble!

Recommended for folks with medium to advanced soldering ability. Soldering and basic tools (like screwdrivers, wire cutters, ruler, etc) required for both kits. A printed assembly guide with detailed instructions, circuit schematics, helpful tips, and experiment suggestions will come included. Great for hacking!!

For the BYOP Kit, the 3D model STL files are available at Thingiverse. Print dimensions are 240mm wide x 112m long x 38mm tall.
