Flutterby™! : Cylon-o-lantern

Weekend before last, Zack brought over a PAiA Theremax theremin that needed some debugging. We diddled about with it 'til the early hours of the morning, got the pitch portion of the circuit tuned, were befuddled by the volume portion, but I realized that when I'm not working on the projects I'm getting paid for, where I can basically say "it's not working" and make it someone else's problem, it'd do me good to build a few things that are more complex than tying a microcontroller to another easily controlled component and get the scope on them.

This morning, Radix forwarded the Cylon-O-Lantern, a carved pumpkin with a circuit to do the "Cylon eye" effect built out of components (rather than throwing a microcontroller at it). Seems like it might be worth soldering that together out of the parts bin just to remember how a 555 works...
