HowTos

64pixels

Want to express yourself the geeky way? Try this tiny display. It can play small animations and scroll some text. It consists only of a few parts and is easy to build. With two AA batteries it’ll give you over two weeks of pixelfun.

See how it’s done at the 64pixels howto.

Tiny Header Boards

These are two tiny boards that make your prototyping on a breadboard much easier. Just plug the header board into the breadboard and attach your ISP programmer and you are ready to go.

Check out the two howtos at Tiny25 Header and Tiny2313 Header.

Programmable LED

Build a tiny circuit with a blinking LED. The blinking sequence can be reprogrammed with a flashlight.
It detects changes in the lighting with a photocell, records the changes and plays them back. A Programmable LED is easy to build and consists of 7 components only, including the battery.

Learn how to build it in the Programmable LED How To.

Synchronizing Firefly

This circuit simulates a firefly with a small microcontroller. If you arrange a couple of them together, they will form a self organizing system and eventually synchronize their flashes.
