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.
USB Component Tester is a universal testing device for electronic components with three or lesser pins. It can automatically detect the plugged-in electronic component and measure the desired component parameters without having the user to manually select the component type, unlike the multimeter. It is based on the popular AVR TransistorTester.

With a custom application built using electron, USB Component Tester provides the user with all desired component insights with a clean and minimal user interface. It works with all OS platforms like macOS, Windows, and Linux based systems. For MacBook Pro users, the application also supports TouchBar Interface.
Usually, many hobbyists, makers, or even engineers have a computer open beside them while working. This USB Component Tester adds a utility to the systems. It replaces other devices such as an ESR Meter, Function Generator, Capacitance Meter, etc. making the workspace free and allowing the user to work more freely.
A HUGE THANKS TO PCBWAY FOR SPONSORING THIS BUILDPCBWay offered to step in and helped me to support this project. They also offered their PCB fabrication and assembly services for the build. They offer 10 custom PCBs for as low as $5 with a wide array of choices such as soldermask colors, surface finishes and much more. The turnout time for PCBs was amazingly fast. They also examine each PCB design manually before manufacturing so you do not receive any defective PCBs. I recommend trying their PCB service if you need one.
You can buy USB Component Tester on Tindie
