Reflow oven – update

The code is finished. I left the connection with the pc out because the crystal had too much drift through the temperature rise and that caused the connection to drop out. (visual basic is very critical what the timing matters).

The code can be found here: Link

A few pictures of the finished oven:

A second part of the assignment in school was to design a pcb based on the pcb of the reflow oven.

The demands where:

  • 8 digital inputs
  • 8 digital outputs
  • 8 analog inputs
  • 2 230V outputs
  • 1 lcd
  • 1 icsp header

My colleague designed the pcb and I soldered it.
