I always upvote Ben Eater's project(s). I got his 6502 kit and worked through his YouTube videos to get it up and running with LCD display and all. I want to actually frame it and get it running, hanging on a wall. If anyone is new to Ben, find a comfortable chair or couch, make some tea, take a breath, and begin your descent into his long-form breadboard series of nerd-splaining how a CPU works, beginning with basic logic gates…

I've been following Ben's videos on YouTube ever since he started this project and have been totally transfixed. His approach to building an 8-bit computer on a breadboard has also spawned a bunch of interest from the community. Just search "my ben eater" on YouTube and you'll find many other people following his steps and making their own computers; some even going as far as to improve upon the original. It's really quite awesome to see. Hats off to Ben…
