Show HN: I made a tiny device for automatically recording digital pianos

Hey HN!

A few years ago, I left my cushy big tech job to make hardware.

And made the device I always wanted - an automatic piano recorder!

I usually play piano improvisationally, and manually hitting record never meshed well with that. But there are always moments I wish I recorded, and now they are!

Hopefully it scratches a similar itch for some of you as well!

A few of the tech details: * built on an esp32-s3 * custom injection molded enclosure * BLE comms, sd card storage, DS1302 RTC * android & ios apps with Flutter * Shadertoy vfx support for video sharing
