To make your TinyCylon you'll need to make the PCB (or have it made), later you might be able to buy it from us!
12 x 1206 SMD LEDs (colour of your choice)
4 x 0805 SMD Resistors - appropriate to your LEDs and the voltage you run the TinyCylon on (1.8v to 5V)
1 x ATTiny85 SMD SOIC and the ability to program it. We use an Arduino Uno with a PROTO shield to program them.
Then you just have to do some fiddly soldering to do.
