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.

Video Description

The PDP-11 supercomputer was originally intended to be used with the Fujitsu Eagle, but ultimately, that’s not going to work out because the Eagle is a bit too new, both for me and for the PDP-11. But, we happen to have a Priam 15450 hiding in the wings, which is both period correct and equally as epic! The only problem is, it looks like the Rock delivered the people’s elbow to the analog PCB. We got some work to do… If you want to support the channel please hop over to Patreon: https://www.patreon.com/usagielectric Also, we now have some epic shirts for sale! https://my-store-11554688.creator-spring.com Come join us on Discord!

Right? 12:28 Go team Javie Martzoukas! 14:00 It was supposed to be a quick and easy episode… (CM) 15:25 I may go a bit off the rails here 16:27 Mean mug! 19:01 Will it work? (Bwahahaha, hell no it won’t) 20:43 The one board we didn’t look at is the one that’s broken, typical… 22:19 !ynnuB
