I wired the brick up as a very small external monitor, so you can, for instance, play Doom on it. pic.twitter.com/uWK2Uw7Egr— James Brown (@ancient_james) June 19, 2022

I haven't shared the schematic because it contains an error; you need to rework the boards to route a spare gpio to the screen. This involves drilling a 0.3mm hole through one of the pads, making a break in the ground plane, and soldering a little piece of wire through. pic.twitter.com/hG5MfYq8N4— James Brown (@ancient_james) June 8, 2022

The new one is more opaque and a closer match to Lego Blue. I also painted the edges of the screen with black lacquer, which got rid of the glowing surround. It¡Çs a very fiddly construction. If I¡Çm going to make more, I need to work on tooling. pic.twitter.com/2AEfSogIfU— James Brown (@ancient_james) June 12, 2022

While that one cures, I added the trench run and got capacitive touch working in the studs. pic.twitter.com/dxzEw2uDI9— James Brown (@ancient_james) June 11, 2022
