A few years ago I entered a Circuit Cellar competition to design a circuit using a Microchip processor. Well, I chose the PIC16F84, and my project was a Surface Mount Device (SMD) reflow toaster oven. I didn't win the competition, but did get a mention in the editorial.


The project was very successful and I now have a very useful tool.

*** WARNING ***

Toaster Ovens contain circuitry that is at mains voltage potential. This voltage is lethal. Do not attempt to do this conversion if you are not confident and qualified to do so.
