circuit board

Tree cricket prototype by kelly heaton

I'm working on a prototype for a series of tree crickets (for my latest "electrolier" sculpture). This board is a little analog synthesizer with options to adjust resistor and capacitor values, thereby achieving different insect sounds. The video shows only one of the sounds --I'll demonstrate others later. 

The wings were laser cut out of Dura-Lar at the Nova Labs Makerspace in Reston, VA. In the video, I'm holding a wire spool to amplify the raw piezo element, for which I need to make a resonant chamber. The piezo is driven with my little "RadioShack copy" amplifier circuit that I blogged about recently (March 12). The board was manufactured in China by PCBWay.
