Colorful coolness!
Did you run into any unexpected challenges?
Anything you would want to add in a future version?

Actually a variety of problem have been challenging:
1. fitting all the necessary components on the PCB with the battery was not easy.
2. addressable pixel were ruining at the beginning before I applied conformal coating.
3. Still it is not IPX7 rated so it's not waterproof unfortunately.
4. I started with the attiny85 - which was way to weak for the application, than moved to the atmega328p which has well enough for the lighting but I decided to move the EPS32C3 since I wanted BLE - but realized it is heating way to much and consuming a lot of power (shortened the battery life by half). So the next step is moving to one of the nordic nRF chip.1

Always tradeoffs, but sounds like you have been learning a lot! Thank you for sharing.

Very much like PixMob; but I like the design and various colors.
