30 year old LED does this with no code whatsoever 🤯 #electronics #LED #tech

This is a 5mm through-hole RGB auto-cycling LED, approximately 30 years old. From the outside it looks completely unremarkable — a standard clear epoxy dome, two metal leads, the kind of component you’d find in any electronics parts drawer. But what’s happening inside this tiny package is genuinely fascinating, and for its era represented a remarkable feat of miniaturization.
