Ardubracelet lets you play Tetris on your wrist

Earlier this year, Kevin Bates developed an uber-mini handheld game console using an Atmel ATmega328 microcontroller (MCU). Having already graced the Maker community with his business card-sized Arduboy, he has now has taken that innovation to the next level with a wearable version of his Tetris-playing gadget. Meet the Ardubracelet!


Equipped with the same chip as his previous creation, the Ardubracelet is powered by the high-performance ATmega328P. The tiny wrist-mounted unit features three bright OLED screens affixed to a flexible circuit board, as well as capacitive strips and a rechargeable battery.

… and you thought that calculator watch was cool!

In terms of battery life, the device can last up to 10 hours and can be easily recharged for those marathon gaming sessions. While you may not think the 0.66” screen makes manipulating shapes all that easy, the responsive touchscreen interface makes matching blocks a simple task.


Though the bracelet itself is only a prototype and may not be as aesthetically pleasing as other wearable devices, Bates aspires to enhance his original design and form factor with a 3D-printed model in the near future.
