#108 Building and testing an eBay Transistor Tester kit

This little kit can be bought on eBay and other places for very little money but no documentation comes with it. In this video, I give some hints on building and using it. The tests are all based on the firmware 1.12K that was originally in the ATMega 328P. This firmware is quite usable but not the latest. There will be a follow-on video about changing the firmware

Documentation and newer firmware can be found here: https://github.com/mikrocontroller-net/transistortester
