If there’s one piece of EDC on your keychain sure to truly get “every day” use, it’s gonna be this. PocketSprite is a keychain-size GameBoy. It features an OLED screen, Bluetooth, Wi-Fi, a rechargeable battery, and a built-in speaker. You can play Game Boy, Game Boy Color, Sega Master System, and Game Gear games, plus the device is open source, so if you got the coding skills, you can load it up with whatever you want. Fully funded on Crowd Supply.
