This DIY Thermostat project is exactly what you think it is, a thermostat you can make on your own. It uses a temperature sensor and a ATtiny as a brain. Two seven-segment led bars show you the current temperature and you can set the thermostat using them as well. Board design, hardware & software are all available in the project write-up.

Hacking an r/c car remote control is actually not a terribly difficult thing to do. But the real reason I put this project up today is because it is strikingly similar to my own “autonomous drifter.” Take a look and delve into the world of r/c car hacking.
