A developer shares a workflow combining Claude Code with a LeCroy oscilloscope (via MCP server) and a SPICE simulator to validate hardware circuits and embedded firmware. Rather than prompting Claude to design circuits from scratch in natural language, the approach gives Claude real-time instrument access and simulation tools so it can get immediate feedback. Key lessons include never letting Claude guess physical connections, avoiding stale measurement data, using a structured Makefile for MCU operations, and keeping raw data out of Claude's context. Three open-source repos are shared: MCP servers for LeCroy oscilloscopes and spicelib, plus demo files.
