This project is based on the work of Martin Kumm.

I made it simpler and cheaper. Instead of using an Arduino I use a ATmega8. This design doesn't use SMD and one single Layer PCB for easy assembly and cheap PCB production and the PCB is only 70x50mm. Instead of using two Buttons to adjust the temperature I use a poti and optionally you can use a standard HD44780 compatible LCD.
