Account of building and selling 2,500 units of MIDI recorder hardware

Sources: Chip Weinberger write-up, HN discussion
Summary: An engineering write-up published 2026-07-19 recounts designing, manufacturing, and selling roughly 2,500 units of a MIDI recorder hardware product, and argues that hardware development is more approachable than its reputation suggests. It covers the path from prototype to production run and the practical lessons on manufacturing and logistics.
Why it matters: First-hand production-hardware accounts are scarce, and the post gives software engineers a concrete view of the manufacturing and supply steps that gate shipping a physical product.
