Also called the ThermoPen, the goal of this project was to create a portable thermometer usable for precise uses case. More particularly, is was created to inspect overheating electronic parts on PCB and for general troubleshooting. At my school, ...
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 ...
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 ...
