So this is a second update for current progress on building PIDKiln controller. This time it’s almost… almost finished 🙂

As you can see I’ve packed everything in two boxes. Right one is 3d printed (model available on Thingiverse) and contains ESP32 board, MAX boards, encoder, switch and sockets. The other box is made of old 3,5” disk drive enclosure. It’s not perfect – but I wanted it to be metal (aluminum in this case) to act as additional heat sink.

On relay box I’ve also made some additional space to hook up current/power meter. I think, after all, it looks quite nite.
