UK-based blogger and maker Daftmike decided to turn his love of the iconic original Nintendo Entertainment System game system into a new project for him to experiment with Raspberry Pi and 3D printing. He created his own pint-sized version of the NES, and even created tiny game cartridges and a pair of mini controllers to go along with it. The Raspberry Pi that powers the mini game system uses a software package called RetroPie that brings several different gaming emulators together. He also created mini game cartridges with NFC tags embedded into them so when it is inserted into the game system and clicked down, the tag tells the Raspberry Pi which game to load into the emulator.
