If you want to see the blinkenlights, first you should go read my other blog post detailing the finished product. Designing the computer First and foremost, I would need to choose a […]
I’m an embedded systems engineer. I spend a lot of my free time looking for things I could use in future designs, or things that tickle one of my fancies.
