LED Matrix Becomes Fun Tetris Clock

Sometimes a project is borne simply out of the fact that some interesting parts have been left sitting around too long. Of course, this is as good a reason to build as any other, and can often lead to some interesting results. [Jorj Bauer]’s Tetris Display is one such project.

The project started because [Jorj] had an 8 x 32 WS2812 LED array laying about, and it was high time it got turned into something cool. The resulting display has several features, making it a welcome piece around the home. It can act as a clock, with automatic compensation for daylight savings and brightness control depending on the time of day. It can also serve as a text scroller, and of course, the party piece – it can play Tetris. It all runs on an ESP-01, with a second device acting as a remote to control the game.

Rather than simply being another LED matrix project, [Jorj] put a little flair into things. A font was developed that allowed the time to be displayed in a pixel font composed entirely of Tetris pieces (or tetrominos). This allows the time to be displayed by pieces dropping from the top of the display. The Tetris implementation is solid, too – implementing the proper Super Rotation System that professionals would expect.

[Jorj] reports that this build was inspired by an earlier Tetris Clock featured in these very pages. It’s a tidy piece that we’re sure is a great addition to the mantlepiece. Video after the break.

Crypto exchange Binance prepares to add margin trading ‘soon’

Binance, the world’s most prominent crypto exchange, says it is close to adding a much-anticipated margin trading feature to its service following weeks of speculation. The company tweeted confirmation of the upcoming feature in a screenshot which subtly teases the imminent arrival of margin trading options. Binance CEO Changpeng Zhao (pictured above) first revealed that the feature was headed to Binance during a live stream following a hack earlier this month that saw Binance lose around $40 million in Bitcoin .

The hidden cost of food delivery

More posts by this contributor What Studying Students Teaches Us About Great Apps I’ll admit it: When it comes to food, I’m lazy. There are dozens of great dining options within a few blocks of my home, yet I still end up ordering food through delivery apps four or five times per week. With the growing coronavirus pandemic closing restaurants and consumers self-isolating, it is likely we will see a spike in food delivery much like the 20% jump China reported during the peak of its crisis. With the food delivery sector rocketing toward a projected $365 billion by the end of the decade, I’m clearly not the only one turning to delivery apps even before the pandemic hit. Thanks to technology (and VC funding) we can get a ri...
