I'm actually more excited to see a new Ben Eater video on youtube than anything else. His stuff is just fantastic. Even though it's lower level than I've ever worked, it's extremely entertaining and educational. His 6502 series is just great, but I want to highlight another couple of videos he did: "Let's build a circuit that displays an image on a VGA monitor! In this video, I talk about how VGA signals work and build a circuit that provides the correct timing of sync signals so that a monitor recognizes the signal." [VIDEO]
