Homebrew PCBs

I wonder if toner would make a good solder mask, used
this way? Obviously you can't coat the whole board,
but just leaving it on the traces and cleaning it off
the pads could be a great idea.

Hmm... another use for toner. Toner is carbon and
plastic, and therefore maybe at least somewhat
conductive. Perhaps some laid down across some traces
could act as a humidity detector. With a reference one
sealed in a box for temperature compensation.
