I designed this from a studio light a friend was scrapping. I replaced the 100 3w LEDs with 50 5mm RGB-auto LEDs, so that they fall out of sync.
the flashing wasn't an initial design feature but it's going to be in a rec room where we will be listening to music so the pulsing and trippy nature worked out in the end.
The LEDs flicker when you turn it off as the voltage flutters down to 0v. The whole thing runs off 240v with a custom wiring setup inside, and a clunky switch from the 1940s.
I have yet to paint the front plastic white to help diffuse it more and I have to fix the wall.
Hope you enjoyed
