Software can now go from a prompt to a product. Hardware still gets buried in datasheets, schematics and specialist tools. Justin is building HeyPCB, an AI-native hardware studio: describe a machine and it creates the schematic, PCB layout, enclosure and fabrication files as a real KiCad project you keep. Justin’s own hardware work spans robotic arms and tactile gloves; he has now mapped 11,000+ open-source boards into Circuit World and built an MCP to connect your favourite AI agent directly to the hardware stack.
