"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…"

Christmas Tree O'Digital Logic

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):…See More

DIY 8x8x8 LED Cube

Building an LED cube has been a project that we have always wanted to do, but the opportunity just never presented itsself. However, recently we were able to get our hands on an 8x8x8 LED kit (that's 512 LEDs!) which provides all the parts (95% of them) and instructions for building your own LED cube. The instructions weren't the greatest, so we went ahead and documented the entire process of building an 8x8x8 LED Cube. Hopefully it…See More
