| Last Update
Because modern electronics components are tending more and more towards becoming SMD-only, and because the associated size reduction can also be very useful for space projects, we need a reflow oven.
Oven has been acquired. It is a cheap 1kW Everglades toaster oven and has been able to do very crude reflow.
A prototype for the controller has been built and successfully measures temperature. I (smeding) am currently hammering out the PID loop to keep it at a fixed temperature. After that, all it needs is a little bit of UI and we should be good to go.
