Show HN: BBRouter – Ben Eater's 8-bit computer, simulated on 3D breadboards

BBRouter 是一款在线工具，允许用户在三维虚拟面包板上模拟 Ben Eater 设计的 SAP-1 8位计算机 1。该项目的核心功能包括实时电路仿真、侧边对比视图以及示波器调试模块 1。开发者旨在为电子爱好者提供一个具备良好用户界面、支持移动端访问且能避免实体接线错误的社区平台 1。

在技术集成方面，BBRouter 实现了原理图的自动同步，并支持通过 MCP 协议连接 Claude 等 AI 助手以辅助构建和故障排除 1。用户还可以直接从 Arduino IDE 上传代码并在模拟器中运行 1。目前该项目提供 Maker 计划，基础费用为每月 7 美元；使用特定代码“HACKERNEWS”可享受首月免费及后续每月 5 美元的优惠 1。

A developer has introduced BBRouter (Breadboard Router), an online tool designed to simulate Ben Eater’s 8-bit computer, specifically the SAP-1 architecture, within a 3D virtual breadboard environment 1. The platform targets electronics enthusiasts who wish to avoid physical wiring errors while seeking a simulator with robust user interface and mobile device support 1. By offering a more realistic and accessible building experience, the tool aims to serve as a community-supported platform for digital logic construction 1.

The core functionality includes a real-time simulation engine that allows users to upload code from the Arduino IDE and run the SAP-1 emulator directly in the browser 1. Advanced debugging features enable side-by-side comparisons and oscilloscope monitoring, with automatic synchronization between the schematic view and the physical layout 1. Notably, the system supports the Model Context Protocol (MCP) to connect AI assistants, such as Claude, for troubleshooting or guiding the build process 1.

Access to the full suite of tools is offered through a subscription model, where the Maker plan costs $7 per month 1. Users referencing the code "HACKERNEWS" receive the first month free, followed by a discounted rate of $5 per month thereafter 1.
