Now building

• vibe-hardware: agent skills that take a device from a plain-language idea to firmware, a KiCad PCB, an enclosure, and a fab order.
• T3: Tool, Toy, or Trash?: the question I ask before building hardware, turned into an agent skill that audits any gadget from its product page.

Earlier open source
