@foerterer@mastoart.social Ah, it's way lower resolution than you give it credit for. It's 48 holes; 48 scanlines. The horizontal resolution is 80 - that's how many times it can refresh the panel during the time it takes one hole to travel all the way across it. 10,000 fps on the panel, 30 fps on the drum, and the visible section is 1/4 of a turn; 10000/30/4 ~ 80. Looked at another way, in a single frame, it can put an image behind a hole at each of 48 rows by 80 cols; 3840 pixels, not lines (albeit 3D pixels).
