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.

My UK publisher, Head of Zeus, has published the official tour schedule for the British tour for Walkaway, with stops in Oxford (with Tim Harford), London (with Laurie Penny), Liverpool (with Chris Pak), Birmingham, and the Hay Literary Festival (with Dr Adam Rutherford). Hope to see you there!
My publicist just found an extra box of the cool promotional Walkaway multitools, and she’s generously offered to give them to the next 100 people to reserve tickets to the May 7th Walkaway event at Chicago’s Royal George Theater, where I’m presenting with CARDS AGAINST HUMANITY creator Max Temkin (current ticket-holders, don’t worry, you get […]
Carol from Cheapass Games writes, “In our continuing quest to bring back the very best classic Cheapass Games, we’re creating a new boxed set of Button Men, our strategy dice combat game. This time around, the characters will appear on cards, rather than pin-back buttons, but since they’re all 1950s era gangsters, the ‘button men’ […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
Yeah, Bluetooth audio is pretty common these days, so why should you care about these earbuds? Look how happy that woman up above looks. She’s got FRESHeBUDS in. Boom. There’s your reason. She’s also at the beach and it appears to be a very nice day.But for the sake of promotion, wireless earbuds are fast becoming the […]
“Gets stuff done,” is a good way to be described by anybody. Especially by coworkers or bosses. Because whether you’re in finance or a children’s librarian, stuff needs to get done. But how do you make sure stuff gets done? You definitely can’t do all the stuff yourself, unless your company/organization/government office consists entirely of you. And […]
