Synchronizing Firefly kit

Alex Weber, of Tinkerlog, who’s brought us such wonderful projects as the programmable LED (featured in The Best of Instructables) and synchronizing fireflies, now offers kits for both of these projects in his new Tinkerstore. Synchronizing Firefly kit sells for 11.50 Euros (about $14.40) and simulates a firefly with a tiny microcontroller. If put together with other fireflies, they will flash randomly. After some time they will start to interact with each other and the flashes will start synchronize until all fireflies flash at once. The kit contains the Firefly PCB, ATtiny13V microcontroller, bright RGB LED (~4000mcd), phototransistor, capacitors and resistors, sockets and header. Not included are a power supply and the ping pong ball. The programmable LED kit sells for 6.50 Euros (about $8.25) and has a blinking sequence that can be programmed with a flashlight. It detects changes in the lighting, records them, and plays them back. The kit includes everything you need to build the circuit, including the 3V coin cell battery. It requires freeform soldered (no PCB).
