What it does

Component Tester in a keychain is a universal testing device for electronic components. It can automatically detect the plugged-in component and measure the desired parameters without having the user to manually select the type, unlike the multimeter.

Being an electronics engineer, I always wanted to have a portable component tester, which could test every electronic component out there. In 2016, I built myself a  Component Tester  based on  AVR TransistorTester  by Markus F. and Karl-Heinz Kübbeler . Following that, I redesigned the Component Tester to size of a keychain . Since makers, engineers and hobbyists have a computer around our work-desk always. So I thought to myself why not build a component tester that could be used as a USB accessory…from hackaday.io
