Happy Holidays!

 

Here's a really fun Christmas-themed 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.

 

More Details (Schematic/Build Log):

We're also running a Kickstarter campaign to fund our second free online electronics course, "An Introduction To Digital Electronics." We have just 4 days left to raise $2,124. We're trying to spread the word about our efforts and need everyone's help!

Hope you guys like this project!

Thanks Marcelo...no microcontroller necessary! ;-)

Although adding a microcontroller could give you a lot better control, we were trying to focus on an all-hardware design approach to give people interested in our kickstarter an idea of what is possible.
