ATtiny Hacks: Infrared guidance and navigation

After [trandi] got his hands on a cheap R/C helicopter he realized the difficulties in actually flying a remote control helicopter. Instead of giving up, he decided to reverse-engineer the infrared protocol and then build a decoder around an ATtiny that would send commands to another microcontroller using a serial connection.

The remote’s communications protocol was decoded with the help … Read the rest

ATtiny hacks: Roll 2d6 with an ATtiny

A pair of 6-sided electric dice (original in Dutch, here’s the Google Translate link) was sent in on the tip line for our ATtiny hacks theme. We really appreciate the simplicity of the circuit; it really shows how the complexity of discrete components can be cut down with a simple microcontroller.

The circuit is very simple – An ATtiny26 serves … Read the rest
