ToastDuino design is based on the Arduino Pro Mini schematic, and also the KTA-259 thermocouple shield by Ocean Controls.
- eight K-type thermocouple inputs
- two 16 amp 250VAC relay outputs
- FTDI serial interface
- 0.25° C resolution
- many I/O features
- program with Arduino IDE
It is intended for semi-permanent programming just like the Arduino Pro mini. Once the firmware is loaded, the algorithm can be adjusted with the potentiometers.
I designed this PCB because I was tired of using my ghetto-rigged toaster oven to reflow boards. It was a dangerous process.
This circuit is really useful, so I did a good job on the PCBs. It could be used for reflow soldering, curing glue, furnace, autoclave, biological processes etc.
