This is fantastic. The one-handed organ keyboard is a work of genius, and it all feels like very simple organic technology: sets of tuned car horns are really cheap, and the rest is just a matter of wiring.
I'm severely tempted to buy a bunch of car horn parts and build my own MIDI-controllable one - every bit of this I can either buy on Amazon or 3D print.
These are not electrically powered horns. Surely you can imitate them though.
No, they're not electrically powered, but given that you can buy an electrically-powered 5-horn kit from eBay for $20, it's certainly the cheapest way to go for a typical HN-reading hobbyist/hacker. Getting 14 horns is then $60, and the rest is relays a microcontroller, and a bit of 3D printing for the horns.
Which is an interesting nerd-sniping exercise in itself: https://www.grc.com/acoustics/an-introduction-to-horn-theory...
