Bill Porter modded an open source hardware design for an LED tie and in one day created the LED Tetris Tie, grabbing pieces of free/open code and designs from around the Web to make his vision a reality. His documentation of the project is an inspiring look at the power and freedom of open. Shown above, v.2, which incorporates gameplay AI.
The tie is made out of 80 WS2811 based RGB LED pixels and is driven by a DigiSpark microcontroller. I pulled in this library written in assembly to drive the display and modified this tetris engine heavily to suit my needs. With limited RAM I had to strip out unneeded features and optimize the code that runs the game similar to Tetris to make it work, I also converted it to support color values as it was originally monochrome only. The code is a definite WIP but posted on here on Github as I play with it in the future. Game moves are random and I plan to attempt some puzzle solving algorithms soon. I had all parts on hand and total project cost comes in around $50.
It’s powered by 2 18650 Li-Ion battery cells in a battery box I used for my Wedding Suit and had lying around. They are installed in a 3D printed battery box with switch.

Crowbcat created a Portal setup that had Chell, the game’s heroine, trapped between two portals that crushed her. The results were an astounding wonderland of psychedelic visuals

Remember back to the time when people thought java was just a hip way to talk about coffee? Or you vaguely remembered from geography class that it’s an island in the South Pacific? We’ve come a long way since then and now that we’ve rocket blasted into the tech future, you’re going to need to […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
