Hi HN, I kept wiring Ben Eater's 8-bit computer wrong, so I built a realistic virtual breadboard editor. Some of the nice features are side-by-side diff, scope, schematics auto-sync, auto-router (BBRouter stands for breadboard router), and my favorites: upload from the real Arduino IDE and connect to your AI with MCP, let Claude & co build it or help you troubleshoot. The link is the SAP-1 running. You can orbit it, probe a hole with the scope, slow the clock down, play with the virtual…

From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
This is cool, but seriously I don't understand why you wouldn't just use Verilog (or VHDL) along with the wide number of associated tools available for it. It's trivially simple to create modules for TTL chips. Also you could design the schematic in KiCad and then export the netlist to Verilog for simulation. Verilog…
How can I hide or move the ram program window? It's blocking the breadboard.
Incidentally I was just thinking about Ben Eater's breadboard setup when I rebuilt a super simple audio circuit (ESP32, MAX98357 ....) from breadboard to a soldered contraption because there was so much noise due to the connectors. Do digital circuits on breadboards not have this problem?
