Ben is always looking for new tools and processes to help with all the projects he builds. He's got a CNC mill, laser cutter, and a 3-D printer, but hasn't found a way to whip up a PCB at his shop. He's hand wired many circuits, but this can be tedious. He's designed PCBs in Eagle and sent them off for production at a board house, but this doesn't help when he wants a PCB the same day. In this episode, Ben experiments with three methods of PCB etching and shares the results.

    Thanks, I tried several types of paper for the direct toner transfer method. For single sided pcb this works fine, but getting double sided pcbs is a pain. I switched to photosensitive pcbs and a uv enclosure. It is some more fiddling with chemicals but it is much easier to line up both sides correctly. The best was whatsoever is to keep it a single sided pcb using zero ohm resistors to skip traces when necessary (or use the pads to attach wire bridges).

    best regards
