A Ping Pong Ball LED Video Wall

Constrained builds are sometimes essentially the most enjoyable. Throw a man-made restrict into the combination, like time limiting your effort or proscribing your self to what’s readily available, and there’s no telling what is going to occur.

[bitluni] really selected each of these constraints for this ping pong ball LED video display, and the outcomes are fairly cool, even when the journey was somewhat tough. It looks as if utilizing sheet metal for the assist of his 15 x 20 Neopixel show was a mistake, a minimum of in hindsight. A CNC router would most likely have made the job of drilling 300 holes fairly a bit simpler, however when all you’ve is a hand drill and a time restrict, you soldier on. Six strings of Neopixels fill the holes, a largish energy provide offers the 18 or so amps wanted, and an Arduino knock-off controls the show. The ping pong ball diffusers are a pleasant contact, even when punching holes in them price [bitluni] a soldering iron tip or two. The show is proven in motion within the video beneath, largely with scrolling textual content. If we could make a modest suggestion, a sport of Pong on a ping pong ball show could be enjoyable.

[bitluni] says that the show is on its strategy to Maker Faire Berlin this weekend, so cease by and say hello. Perhaps he’ll have a few of his different cool builds too, like his Sony Watchman Game Boy mashup, or the electric scooter of questionable legality.
