I bought this oven for $7 from my University with the intention of turning it into a temperature controllable reflow oven. It was already being used as a reflow oven, but I wanted something a bit more controllable. I snagged some cheap parts on ebay for turning it into a temperature controllable oven and it works just fine! There are a few improvements I will possibly make in the future:
- Consolidating AC connectors! The single oven has to have 3 different connections to mains... One for the oven, one for the temperature controller, and one for a 12V wall wart that powers the 15A relay inside. I could, in the future, tap off of the mains connector inside of the oven for all of these, but for now it was easier to just use separate connections.
- Add a real reflow controller. This one is obviously just able to set a temperature and stay there, which isn't necessarily ideal for reflowing. Ideally, I'd have a controller that can do a set temperature profile instead of just going to a set temperature.
