Here's the first version of the reflow ovens brain, I've thrown this together while I wait for the oven to arrive.
So far it has:
- Teensy LC for running reflow logic
- Adafruit AD8495 breakout for temperature sense
- Decent length k-type thermocouple
- 4-18v switched, 240v load solid state relay
Teensy LC doesn't output 5v, so I've dropped in a simple 5v charge boost and switching the 5v to SSR using a simple NPN relay (relay-ception)
I've gone for this oven from Amazon. I hope my house doesn't burn down.
