flickering advent window LED lightsbeatbuzzer (33) in diy • 7 years ago First Test of my selfmade flickering LED window lights. The flicker LEDs are dismounted from LED tealights, set on aluminium tubes fixed in a piece of wood. They're all current limited by a resistor and then wired in parallel to a 5V power source. ▶️ DTube ▶️ IPFS diy technology electronic science dtube
