@thomasfuchs have you heard of the Cromenco Cyclops? It uses a decapsulated 1 kilobit DRAM chip as the image sensor and can be built from plans in Popular Electronics (Feb 1975). Here's a selfie at an astounding 32x32 pixels:
@th @thomasfuchs
I remember a project to add digital video input to the BBC Micro, sometime in the 1980s, using this exact method.
@robert @th @thomasfuchs reminds me of the cover of the 8-bit Neuromancer game.

@th @thomasfuchs oh gosh yessss the cromemco dazzler. I need to build one at some point.

Has anyone converted the magazine PCB layout to Gerber's yet?

@th @thomasfuchs Oh, wow, I worked on Cromemco machines for *years* and never heard of this one.
@th @thomasfuchs now I want one. I hate you
