Who needs delivery when you can create your own pizza oven?
If you come across a broken pizza oven that you’d really enjoy using, but the control system is broken, what are you to do? If you’re imgur user “maschlue” — or hopefully many of the readers of this blog — the answer is to retrofit it with Arduino guts!
This build starts out with a mechanically sound pizza oven with just one “little” problem, the temperature regulation didn’t work properly. When turned on, the coils stayed on constantly, so it would seem that the pizza would either be badly undercooked or burned. Fortunately, maschlue didn’t give up, and installed two new thermocouples in the oven with an Arduino Nano (ATmega328) for control.
The oven was first gutted, stripping away much of the original wiring and even the back insulation. The new thermocouples were then installed, and the insulation was replaced. After the replacement, the new circuit — including relays, the Arduino, potentiometers for temperature control, and a Nokia 5110 display unit — were installed in its place.
Once the new electronics were implemented, a beautiful faceplace sourced from Schaeffer AG was installed. Switches and lights were recycled, and along with new knobs and the Nokia display, the end product “Doctor Thunder Cook” looks really great. The resulting pizza looks quite tasty as well!
