Are you tired of lugging around huge portable retro gaming systems that you can’t even fit on a Post-it note? If that’s the case, then the TinyPi looks like the device for you, as it claims to be “the world’s smallest Raspberry Pi-based gaming device.” While this may seem like a bold claim, you might note that the Tiny Pi PCB fits flush with the Raspberry Pi Zero, which measures just 65mm x 30mm—defining how small a Pi-based device can be.
Interestingly, the project started out as something of a joke, but judging by the fact that they’re sold out as of this writing, there’s certainly a market for really tiny gaming devices. Get on the waiting list if you’re interested!
While the graphics and controls are illustrated quite nicely in the video below, as with the Pi Zero itself, it would seem difficult to grasp just how small it is until you physically pick one up! That means some advanced soldering techniques are needed, like soldering the board flat to the Pi Zero (cool!) which is shown in the assembly guide. There are also some early tests toward 3D printing a case for this over on the Hackaday.io project.
