BBRouter puts Ben Eater's 8-bit computer on 3D breadboards you can rewire in the browser
The browser simulator runs Eater's SAP-1 live, generates build sheets from virtual wiring, and lets Claude inspect and rerun circuits through MCP for $7 a month.

Why it matters
Breadboard computers fail in physical details that schematic simulators hide: a wire one row off, a floating input, a missing decoupling capacitor. BBRouter rehearses the real build in 3D, prints the cut lengths, and gives AI assistants direct access to inspect and run the circuit, turning agent help into testable changes.
The maker of BBRouter started with a familiar failure. "I kept wiring Ben Eater's 8-bit computer wrong, so I built a realistic virtual breadboard editor," the maker wrote in the November 1st post introducing the project.…
