It hardly seems possible, but engineer collective and split-flap display purveyors [Oat Foundry] were able to build a working implementation of Tetris on a 10 x 40 split-flap display in the span of a single day. Check it out in the video after the break.
This project is a bit understaffed in the details department, but we do know that [Oat Foundry] started with [Timur Bakibayev]’s open-source implementation of Tetris in Python and modified the
draw function to work on a split-flap display. As you may have guessed, the biggest obstacle is the refresh rate and how it affects playability — particularly during those tense moments when a player rotates a piece before dropping it. Split-flaps flip quickly from on to off, but flipping back to on requires a full trip around through all the other characters.
We think this is nice work for a one-day build. Should they go further, we’d like to see the same things implemented as [Oat Foundry] does: a high score tracker and a preview of the next piece.
Don’t have a split-flap display? Yeah, us either, but we do have televisions. Turn on the tube and check out this Nano-scale Tetris.

There is a boring part of every computer introduction class that shows how a computer is made up of input, output, and processing. Maybe it wouldn’t be so boring if the input device was a nunchuck. [Brian Lough] thinks so and he belligerently asserts that nunchucks are the best input device ever. With a simple connection to a Wii controller and an associated library, you get access to an analog joystick, two buttons, and an accelerometer.
The nunchuck is meant to plug into a Wii controller and the connection is I2C, so that’s trivial to interface to an Arduino or other small microcontroller. The only issue is making the connection. We might have just snipped the wires, but [Brian] prefers to use a small breakout board that plugs into the stock connector and provides solder points for your own cable. There are options for the breakout boards, and [Brian] has his own design that you can get from OSHPark for about a buck for three boards. You can also just jam wire into the connector, but that’s not always robust.

[Greg] loves hacking his bow ties. Back in high school, he added some bright RGB LEDs to the bow tie he wore to prom and even won the male best-dressed award. Recently he decided to try another bow tie hack, this time giving his tie some retro arcade game feels.
He decided to use an ATtiny85 and to experiment doing some more lower-level programming to refresh his skills. He wrote all his libraries from scratch which really helped him learn a lot about the ATtiny in the process. This also helped him make sure his code was as efficient as possible since he had quite a bit of memory constraints using the ATtiny85 (only 512 bytes of RAM).
He designed the body of the bow tie with wood. He fit all the electronics inside the body while allowing the ATtiny to protrude out of the body giving his bow tie some wanted hacker aesthetic. Of course, he needed to access the toggle switch to play the game, so he made a slot for that as well.
Nice addition to the electronics bow tie collection on Hackaday. Really aesthetic design if you ask us. And you know how much we love retro games.

[Michael Pick] calls himself the casual engineer, though we don’t know whether he is referring to his work clothes or his laid back attitude. However, he does like to show quick and easy projects. His latest? A little portable Tetris game for $9 worth of parts. There is an Arduino Pro Mini and a tiny display along with a few switches and things on a prototyping PC board. [Michael] claims it is a one day build, and we imagine it wouldn’t even be that much.
Our only complaint is that there isn’t a clear bill of material or the code. However, we think you could figure out the parts pretty easy and there are bound to be plenty of games including Tetris that you could adapt to the hardware.

Tetris may have first arrived in the West on machines such as the PC and Amiga, but its genesis at the hands of [Alexey Pajitnov] was on an Electronika 60, a Soviet clone of an early-1970s DEC PDP-11. Thus those tumbling blocks are hardly demanding in terms of processor power, and a game can be implemented on the humblest of hardware. Relatively modern silicon such as the Atmega328 in [c0pperdragon]’s Arduino Nano Tetris console should then have no problems, but to make that assumption is to miss the quality of the achievement.
In a typical home or desktop computer of the 1980s the processor would have been assisted by plenty of dedicated hardware, but since the Arduino has none of that the feat of creating the game with a 288p video signal having four gray scales and with four-channel music is an extremely impressive one. Beside the Nano there are only a few passive components, there are no CRT controllers or sound chips to be seen.
The entire device is packaged within a clone of a NES controller, with the passives on a piece of stripboard beside the Nano. There is a rudimentary resistor DAC to produce the grey scales, and the audio is not the direct PWM you might expect but a very simple DAC created by charging and discharging a capacitor at the video line frequency. The results can be seen and heard in the video below the break, and though we’re sure we’ve heard something like that tune before, it looks to be a very playable little game.

Tetris was a breakout hit when it was released for the Nintendo Game Boy in 1989, in much the same way that Breakout was a breakout hit in arcades in 1976. Despite this, gamers of today expect a little more than a tiny monochrome LCD with severe motion blur problems. Enter the LED Tetris build from [Electronoobs].
The build relies on a hacker favourite, the WS2812B LED string. The LEDs are set up in a 8×16 matrix to create the familiar Tetris playfield. Buttons and a joystick are then installed on the front panel to allow the player to control the action. An Arduino Mega runs the show, with a DFPlayer used to play the famous theme music as the cherry on top.
It’s a fun build that would be an awesome addition to any hacker’s coffee table. Big glowing LEDs make everything better, after all – this ping-pong ball display is a great example of the form. Video after the break.

[Paul Klinger] can’t seem to get enough of building tiny, amazing gaming rigs, and we love him for that. They combine two of our favorites: miniatures and portable gaming. His newest creation honors the form of the formidable ThinkPad.
Of course it has the red nipple and lid LED—wouldn’t be a ThinkPad without ’em. ThinkTiny’s nipple is a 5-way joystick that plays Snake, Tetris, Lunar Lander, and more on an OLED screen. Like its predecessor the Tiny PC, [Paul] used an ATtiny1614, which (FYI) has a new one-wire UDPI interface. He can easily reprogram it through pogo pin holes built into the case.
There are some nice stylistic details at play here, too. The lid LED is both delivered and diffused by a 2mm grain of fiber-optic cable. And [Paul] printed the cover with a color change to transparent filament to make the Think logo and the charging LEDs shine through. Maneuver your way past the break to see it in action.
If you haven’t leveled up to AVR programming yet, introduce yourself to Arduboy.
