The Gakken SX-150 Analog Synthesizer Kit from the Maker shed is a really fun kit to build, mod, and hack. The first time I tried one out was at Maker Faire in 2008 and I was really impressed by the sound this little synth kit was able to produce.


  • Size: 4.5″ x 6″
  • Controls for LFO, pitch envelope, frequency cutoff, resonance, and attack/decay
  • Slide controller (pen type electrode)
  • Output and external input 1/8″ jacks
  • Small built-in speaker

Collin did an excellent video review of this cool little synth a while back on the blog. Check out the custom “pick” buttons he added to the stock kit.
