I Built a Beautiful Card Tester for the Data 620!

About

Welcome to Usagi Electric! On this channel, we dive into old school technology, focusing heavily on vacuum tubes. My primary goal is to build computing circuits based off the legendary machines of yesteryear, only with a slight modern twist. All the tubes will be operating with very low voltages on the plate, making the projects safe and easy to follow along with. So, lets grab our multimeters, some random tubes and a low voltage power supply and have fun! Usagi Electric covers one of my main passions, while my other main passion can be found over on Usagi Motors.
