And even launched Minecraft
Modern portable game consoles are equipped with screens with a diagonal of 6-7 inches. Smartphone screens have the same diagonals, only with a different aspect ratio. There are compact consoles for old games, and there are Tamagotchis. And the author of the channel Basically Homeless showed what he calls the smallest gaming monitor in the world. And at the same time I created a device with this screen.
Screen width — less than 6 mm. The resolution is 640 x 480 pixels. And with such a display, the author created a portable gaming device. The basis was a single-board PC Raspberry Pi RP2040 and a pair of Joy-Con controllers.
The author even launched Minecraft on this device (strangely, not Doom), although in fact much more is possible — the possibilities are limited only by the Raspberry Pi RP2040 itself.
Of course, this is just a project implemented for fun, because on such a screen it is simply impossible to see anything without some kind of magnifying devices.
