Over at Instructables, Osprey22 (what’s your real name, 22? Let us know and I’ll add it to this post) is driving audio and eight strands of lights (plus a jolly twinkly star) from the same Raspberry Pi, so the two can be sequenced using some custom Python he’s written. Play to the end for a bit of Let it Go, if you’ve not heard it too many times this year already.
Osprey22 has made full build instructions available, along with all the code you’ll need, and sequencer files for a few Christmas choons. We love it.
