My Pretty Bird circuit is about to fly to China and get bigger.
My first run of boards came in this week. I am pleased to report that the circuit works as intended (sings an analog electronic song). I’ll post video of that soon, but for now, some photos of the pretty board. I used gold-plated copper and solder mask to achieve a watermark effect, as you can see in some of these pictures. These boards (along with components to solder) will be given to attendees at Creative Capital’s 2019 retreat in June.
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.
