Christmas Tree O’Digital Logic

Posted on Tuesday, December 18th, 2012 in Holiday, LEDs by the machinegeek


Chris from PyroElectro writes about his holiday project. “It’s an all-digital-hardware LED Christmas tree we’re calling the Christmas Tree O’Digital Logic. The tree itself is composed of 64 LEDs built into a spiral sitting on a piece of protoboard. Underneath, the controller uses shift registers and a 555 timer to create two modes of display: a predictable pattern and a random pattern. This should light up any desk or shelf and bring merriment to your readers. Happy Holidays!”

You can find all the details on Chris’ Yuletide project on his PyroElectro website.

When not developing hardware projects, Chris has been working on his second free online electronics course, “An Introduction To Digital Electronics” which he’s funding via Kickstarter.
