The full story

The maker has more than 20 years in the field and found existing synthetic aperture sonar and radar simulators outdated or hard to use. Over two months he built ApertureLab, which he intends as a stepping stone to generating synthetic data for training world models.

He had written code for the individual pieces at past jobs but never had time to assemble them. He brought the sonar, radar, ML and CUDA expertise and used Claude Code to put it together.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
