BBRouter
Realistic virtual breadboard editor for 8-bit computers
About
BBRouter is a realistic virtual breadboard editor that lets you build and debug Ben Eater’s 8‑bit computer in a 3‑D environment. It offers side‑by‑side diffs, a scope, automatic schematic‑to‑breadboard sync, and an auto‑router. You can upload code from the Arduino IDE, connect an AI to help build or troubleshoot, and even slow the clock or interact with virtual displays for debugging. The interface works on mobile and with trackpads, making it a practical tool for hands‑on learning and real buil
The case
Who it is for
Electronics hobbyists and makers who build Ben Eater’s 8‑bit computer and want a realistic, mobile‑friendly virtual breadboard with AI assistance.
What is broken today
Before BBRouter, wiring Ben Eater’s 8‑bit computer was error‑prone because most simulators are offline, abstract, and lack a realistic 3‑D breadboard view or a mobile‑friendly interface. Debugging required manual inspection, and there was no easy way to sync schematics with the breadboard or use AI to help build.
What it does about it
BBRouter simulates a 3‑D breadboard, provides side‑by‑side diff, a scope, automatic schematic‑to‑breadboard sync, and an auto‑router. It allows uploading code from the Arduino IDE and connects to AI via MCP for building or troubleshooting. The simulation runs in real time, enabling users to probe holes, slow the clock, and interact with virtual displays.
Why not the obvious alternative
Unlike other offline or abstract simulators, BBRouter offers a realistic 3‑D breadboard view, real‑time scope, auto‑routing, schematic sync, mobile and trackpad support, and AI integration for building or troubleshooting.

Questions
- What is the pricing?
- BBRouter offers a Maker plan at $7/month. If you use the code HACKERNEWS, the first month is free and thereafter $5/month.
- Does it support uploading code from the Arduino IDE?
- Yes, you can upload code directly from the Arduino IDE into the simulation.
- Is there AI integration?
- Yes, you can connect to AI via MCP, allowing tools like Claude to help build or troubleshoot.
- Can I use BBRouter on mobile devices?
- The interface is mobile‑friendly and works well with trackpads.
- What features does the auto‑router provide?
- The auto‑router automatically routes connections on the breadboard to match the schematic, reducing manual wiring.
