I have made this with 49 self flashing LED. It's a very colorful flashing light. You can get a psychedelic trip without LSD, so it is free and legal ;-)
Schematic: USB-powered, all LED parallel (I have used 2-pin-flashing-LED), 2 Diodes 1N4007 in series to reduce the voltage.
Alternatives:
-- standard LED (add current limiting resistors to each colour of LED.
-- Schematic like a LED-Cube, so you can program your own sequence.
printed in PLA silver-grey. hole for cable is drilled (not printed). Upper part has a column for support, cut it after print. No support. Both parts glued (after soldering).
new idea: use as "tv-simulator" when you are not at home. With self flashing LED it is identical to a $10 device sold in penny store.
