Refreshing the Singing Pumpkin Display

Posted on October 10, 2015 by Pipkins, Royce

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.
