Pretty happy with how this one turned out. I built my dekadrone in its own enclosure built from pieces of a curbside find crate.
I added 3.5mm jacks to same side as the power jack.
The waveform of a single oscillator is pretty interesting:
Gets complex pretty quickly, though:
I built it with three 1uF, four 10uF, and three 22uF capacitors. Time for some power chords!
