Show HN: Mechanical Computer Kit (Roons)
I built a mechanical computer kit: https://whomtech.com/show-hntl;dr: it's a cellular automaton on a "loom" of alternating bars, using contoured tiles to guide marbles through logic gates.It's not just "Turing complete, job done"; I've tried to make it actually practical. Devices are compact, e.g. you can fit a binary adder into a 3cm square. It took me nearly two years and dozens of different approaches.There's a sequence of interactive tutorials to try out, demo videos, and a janky simulator. I've also sent out a few prototype kits and have some more ready to go.Please ask me anything, I will talk about this for hours.-- Jesse Comments URL: https://news.ycombinator.com/item?id=43859464 Points: 3 # Comments: 0
