Show HN: I made a pulsing conductor's baton

https://bertwagner.com/posts/creating-a-pulsing-conducting-baton-part-1/
1•bertwagner•59m ago
Hey HN. I've spent the last few months building this vibrating metronome that fits in the handle of a music conductor's baton.

While I'm proud of this first version, I have lots of ideas on how to make version 2 better. If you have suggestions for how to improve it, I'd appreciate the feedback.

Thanks for taking a look.
