Temperature Controlled Fan With LED Status
This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined...

PICTIL – Remake of the TIL311 hex LED display
Yann Guidon @ hackaday.io rebuild the TIL311 hexadecimal display using a pic microcontroller. He writes: The TIL311 is a nice but expensive, obsolete, power-hungry hexadecimal display. It would be cool to make a tiny module with similar functionality which solves its shortcomings. A...

Programmable LED dimmer
A Programmable LED dimmer from Soldernerd: Around one and a half years ago I’ve designed and built various LED dimmers for both white and RGB LEDs. Then late last year someone approached me asking if I could make an RGB dimmer for him, too. But my designs were really tailored to...
