  As you can see from the gallery and the YouTube video, this is finished and working. I edited the components list to show the capacitor values I decided on.

• Spitballin'

  Design circuit with the enclosure in mind.

  • Inputs are LDRs, so they must be accessible to the user.
  • Enclosure is metal. Must not short things together.
  • Oh yeah, I have some tiny heart-shaped foam stickers. I'll poke the LDR legs through them and stick them to the top of the box.
  • I can use wire insulation as leg warmers on the LDRs, since I'm running out of really skinny heat-shrink tubing.
  • LDR legs must be lengthened so that the user can replace the battery without destroying the circuit.
  • Okay, cool. If I wire-wrap the legs once I stick them through the lid, they'll have nice, flexible extensions to the board. Plus, I get to wire-wrap.

  Find the most appealing capacitor values.

  Sure, this is an extremely lo-fi synth. But it might as well be as appealing to play as possible. I have three sizes of LDRs, so it's worth experimenting with capacitors to find pleasing frequency ranges.
