Jerry O'Keefe The circuit tracer in Figure 1 is a handy tool for finding connectivity paths on a pc board. Because the sense voltage you use to measure the path is lower than a transistor's V BE voltage, you can use the design in circuits ...
I'm just toying around with this idea at the moment. If I start using photo exposure PCB type production, I'm probably going to need a light box. I have tried using spray on photo-sensitive resist and exposure to the sun. It was a complete ...
