2. Using Copper Traces As Ballast Resistors Ensures Balance
   Circuits Printed Circuit Boards (PCB) Supply Analog Devices LT3080
   The data sheet for the LT3080 linear voltage regulator suggests using printed-circuit-board (PCB) traces for ballast resistors. Although the LT3080’s low offset voltage suits it well for this technique, it can be used for other ballast ...

3. Design makes handy audible circuit tracer
   Circuits Measurement Printed Circuit Boards (PCB)
   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 ...

4. UV Exposure Light Box
   Circuits Tools and Technologies Printed Circuit Boards (PCB)
   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 ...
