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.

Libretaxi is an open source project that lets anyone become a rideshare driver in less than a minute; it has more than 20,000 users worldwide, and is maintained by Roman Pushkin, who started the project in December 2016 and is now planning to quit his job and work on it full time.
Mister Alphabet is an action-figure designed to cleverly bend and contort into every letter of the Latin alphabet; the website is long on trademark warnings and arty Instagram photos, but short on details, like, “Is this an object of commerce?” and “If so, where does one buy it?” (via Kottke)
John Deere is notorious for arguing that farmers who buy its tractors actually “license” them because Deere still owns the copyright to the tractors’ software; in 2015, the US Copyright Office affirmed that farmers were allowed to jailbreak their tractors to effect repairs and modifications.
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
