Instructables contributor thomasj152 put this cool wanting timepiece collectively by assembling a grid of 128 particular person ping pong balls, with every of them backlit with an RGB LED from a strip mild.

Whereas the thought of reducing open 128 ping pong balls after which wiring up all the LED strip mild sounds sophisticated, its builder says it was really fairly straightforward to do, and he’s supplied particulars on your to make your personal over on Instructables, full with the code required to run the clock. With somewhat programming talent, you may use the LED matrix to show different pictures or animations too. Possibly you may even rig it as much as play PONG.
