ATtiny13 + 8* 74hc595 Shift Registers. It have two modes: random matrix and binary counter clock. Code: https://github.com/taunoe/attiny13-shift-matrix
My third freeform electronic light sculpture. It runs on ATtiny13 and uses 5730 (5.7*3.0 mm) Worm White SMD LEDs.
I had a bunch of smd LEDs and no idea what to do with them. But then, when I had watched all these events in Hong Kong. And when I had seen how they make this paper cranes I decided to make my own version. It use ATtiny13 AVR microcontroller and software PWM to slowlyContinue reading “Electronic “paper crane” or orizuru – freeform circuit”
