Hey guys, I built this clock. I had a friend help me with the woodworking for the case. I used an Arduino board as the compute platform and designed and 3D-printed the display components using several LED strips. I wrote all the code.

It shows hours and minutes, metric time and the current decibel level.

@mikeolson so nice!
On the other end of the spectrum, I've just finished a super minimal colorful clock, enclosed in a wooden box as well, with only two digits.
Hours and minutes are displayed alternatively for few seconds each. I'm using an #Arduino Nano R4 and a bunch of neopixels.
I'm going to present it on March 28th for the Arduino Days 2026 at the local Arduino User Group in Milan, Italy
