I would like to get a set of prusa electronics made up so I can build a
prusa (probably a hybrid with imperial rods and nuts for the frame,
metric everything else).
I've done smt skillet soldering once before on a regular electric range,
it wasn't too bad at all. We were using SOIC chips and 1206 leds (so
pretty big on the led front, but 0805 isn't much harder). I could
definitely help out with the smt soldering part.
