World's worst video card? The exciting conclusion
Why Hacker News recommends it
Recommended as an accessible, educational build that anyone with basic logic knowledge can follow.
What it is
Ben Eater finishes building a minimal VGA video card from logic circuits. He explains analog RGB signals, stores an image in an EEPROM and builds a simple digital-to-analog converter to display it.

Not the same thing, but you reminded me of this since it's in a similar vein. Ben Eater went through the entire process of building a VGA "video card." Anyone with a basic understanding of logic circuits has enough background to understand it. Worth a watch. Part 1: [LINK] Part 2: [this video]

If you're a visual learner, check out Ben Eater's channel: [LINK] He has a really great video series where he builds a small computer from scratch on breadboards. Also some other highlights: Reliable data transmission, more educational: [LINK] DIY VGA "video card": [this video] Super educational, but if you want to get into more embedded hardware hacking, I would say that building a homemade computer like he does is probably not a super exciting place to start. I'd recommend picking up some Teensy 4.0 microcontrollers and build some small hardware projects with the microcontroller before diving into lower-level circuitry.

At 3:00 into the second video, he talks about hooking it into a computer. [1] It does a quick flash to what might be his breadboard computer. So I think he intends to connect this to the computer he has built. 1. [this video]
