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 slowly fade wings on and off.
First I made paper crane and the rest is copy-paste basic forms. The basic shapes are actually simple and flat. The most difficult part is soldering SMD components.
All electronics and batteries (4 x AA) are in the bottom wooden box.
I used Arduino IDE to program ATtiny13.
