Same. It's a solid four-note ARP that sticks to a fixed set of musical keys. You literally can't make bad sounding music with this. A more grown-up version of this would be 16 notes, with variable length patterns (4-16?), and a "swing" function. A little bit of I/O mux under the hood and I bet this design could be expanded in that way. Or maybe you just daisy-chain multiple sequencers?

How are these, are they worth the money? I have seen these before, but thought they might be crappy "jokes". However, if they are decent, I would love to play around with them.
Looks amazing! Reminds me of a funny reddit thread about a man who built a fiber optic star ceiling for his daughter. The top comment was "First child?". :) https://www.reddit.com/r/DIY/comments/8g8pce/fiberoptic_star...
And then the things you do to redeem your guilt for the second child is a whole interesting area.

Wood is also pretty child friendly. But neither injection molding nor carpentry will protect a synth from a child dunking it in a puddle of water.
Best of luck with your Kickstarter!
Thanks for all the kind words and feedback. There are some comments expressing interest in supporting a Kickstarter etc. If you're interested in receiving updates you can leave your email here: https://tally.so/r/Y55dXv Thanks again - this was a bit of a surprise!
Lovely project and a really great idea. Have you come across soft tooling for injection moulding? It's a lower cost, short run approach using much less durable moulds from various materials.
I didn't know that was a thing - I'm going to look into it.
It's not kid friendly, but in case anybody's interested I just wrote up how I made a simple "hardware" synth by bodging together a Raspberry Pi Pico 2 and I2S audio module, total cost around £10 on Amazon UK. The hardware's very cheap and easy. The "default" synthesis is pretty simple but also pretty hackable (in Rust) if you want to customize it. https://github.com/Joeboy/oxynth/
Thanks for sharing! I did some similar playing around with an ESP32 and I2S a few years ago (lockdowns were an odd time). Where I seem to remember getting stuck was how to get the phase to line up, so that each sample looped at a zero-crossing point (which is different for each frequency). For the lazy, what did you do? https://gitlab.com/afandian/melodicornamuse/-/blob/main/melo...
Edit: Ok I glanced at your code, if I read it right it seems like you're writing sin waves into buffers at "init" time then copying the appropriate buffer at "run" time. Which is not what I'd do, but then I'm used to more luxurious devices. Maybe try using a fast sin approximation rather than the precomputed buffer table?
