Temperature controlled fan using PWM microcontroller

This project gives you a simple temperature controlled fan. If the difference between real temperature and the user temperature is high then the fan will run at full speed and if the difference is low then the fan will rotate at slow speed. The speed of the fan varies with the temperature. The user can

Hack a Toaster Oven for Reflow Soldering using ATmega32 microcontroller

Hack a Toaster Oven for Reflow Soldering using ATmega32 microcontroller

As I get more serious into my electronics hobby, I need to work with more SMD components. Some component packages are very difficult or impossible to solder with a traditional soldering iron. To solve this problem, I decided to hack a toaster oven to become a reflow soldering oven. Basically, to perform reflow soldering, solder
