I finally got around to building an Electronic Dummy Load. I found a few schematics floating around the web and everyone keeps tossing a AVR into the mix. A simple analog device is perfect for testing a power supply. So I did a little research and came up with a nice small device. Since I attend to rip parts from CRT televisions I have a good stock pile of mosfets and power resistors. I’m using two 6.8ohm three watt resistors in parallel and a FQS9n90C TO-3P N-channel mosfet. A simple LM358 opamp to control things. For a power source im using a 7815 regulator and a typical wall wart for isolation. When I am finished with the build I will post the schematic and pictures.
