Built inside a jar, this synthesizer has a square-wave oscillator as well as sweeping LFO modulation effect. The pitch and speed are controlled by outside light sources hitting the two light sensors inside so there is a lot of room for experimenting.
All of the components are built in a three dimensional floating circuit that comes down from the lid of the jar.

A yellow LED pulsates in time. There is a single switch on top for power which is supplied by an included 9v battery, and a 1/4" output jack that makes it easy to connect to amps, effects, or recording equipment.

This was hand-built in a series of six.

    Thanks.

    It is just a demo to show how it works and sounds, completely raw.

  • Would it be possible for you to post your schematic, or would that be like giving away your trade secrets?

  • @tamaleaga10

    I don't have a schematic put together but it is 555 timer with a 40106 IC. If you have more questions feel free to ask.

  • Excellent job !
