Fun concept and congrats on the product!
I’ve shipped out the first few units of my solo project a couple of weeks ago (a super niche tool for DJ's):
Feels good to follow through from a hobby project to an actual shipping product. Its been fun re-igniting all the things learnt during electronic engineering classes back in university.
What is an interesting contrast is that by day i'm a web/ios software engineer where memory and disk is largely plentiful, but by night i work on cramming TCP/IP + USB stacks and real-time audio decoding threads into less than 80KiB of RAM on a Cortex-M4 MCU.
Currently busy ramping up production of a small batch of units and adding checkout to the website.
