I’m getting my original singing pumpkin display ready for BVNA’s Pumpkin Pavilion and Halloween. The original display was pure prototype electronics consisting a bunch of stuff from Adafruit: an UNO, a Wave Shield, a PWM/Servo driver, and servos. There was a footprint challenged custom PCB for a TDA7297 and some junk bin DC-DC convertors.
It didn’t look pretty, but it did the job for years. However, the new fully integrated prototype controller looks a lot snazzier.
There are still more design changes to come for this board, but it was really nice to see it perform as intended in my full display.
