LED "Ball" clock

I built a Ball Clock originally from 3Dadicto (https://www.thingiverse.com/thing:4786491). It worked great with the many design changes, but was too noisy. I used a Raspberry Pi Pico to drive the stepping motor at exactly 1 rpm, which was a challenge in itself since the process time plays a large role in accuracy with ~ 7.4 uSec delay per line of code, and running with an output of 53 Hz, the loss was noticeable. So… I built an LED equivalent using the Python programming to do the adding the physical ball mechanism accomplished. The timing loop is only 1 cycle per minute with only 8 lines, so a 941 uSec pause was need in the program. It is all shared in the attached document “LED "Ball" clock.docx” .
The box and face are printed in PLA with a color change for the digits. There is also an aligning part to glue (super glue) the face frame to the face. Also included is an LED removal tool – so you can support the back side to tap a failed Led out. This is needed because the 38
