BBRouter - Simulate Ben Eater's 8-bit computer on 3D breadboards
Show HN: BBRouter – Ben Eater's 8-bit computer, simulated on 3D breadboards
BBRouter brings Ben Eater's iconic SAP-1 8-bit computer to life in your browser with interactive 3D breadboards. Wire up chips, LEDs, and switches just like on a real bench, then run the simulation to watch your build execute instructions. The platform pairs a visual board with a synchronized schematic, so every connection stays in step. Beyond the prebuilt SAP-1 project, you can design your own circuits from a rich parts library and even let AI assistants like Claude modify and run projects via the MCP server. It's a hands-on way to learn computer architecture without the risk of fried components.
Every wire you place on the 3D breadboard is mirrored in the schematic, and the simulation runs your circuit exactly as it would on a real bench—no soldering iron required.

Congrats on the launch. Have fond memories of early 2k where everything starting with bb was amazing

This looks amazing. Congratulations on the launch.
I was hoping to find Ben's Digital breadboard clock [1] in there, I'm currently building it!

How can I hide or move the ram program window? It's blocking the breadboard.
