This new guide from John Park presents a fully modernized prop blaster hardware and software combo!
This guide is an overhaul of the Lucio Blaster project from 2017. You can use this as a leaping off point for any prop or cosplay element that requires lights, music, and triggered sound effects.
A lot has changed in three years, and the project has been greatly simplified, thanks to advances in hardware and software! We’ll now use the Feather M4 Express running CircuitPython and a Prop-Maker FeatherWing.
Thanks to dual-stream, native .mp3 playback in CircuitPython, we can eliminate the need for multiple pieces of hardware previously required to play music and sound effects at the same time, and the power, amplification, and NeoPixel driving circuits have been similarly simplified.
And speaking of NeoPixels — the LED animation library makes it astonishingly simpler to create highly awesome lighting effects!
