Keychain Gameboy
Created on 14 Nov 2017
Scratch built emulation of Gameboy in an adorable form factor
Remember the 90's? Trading Recees for string cheese, crying when your teacher killed your Tamagotchi and of course, trading
Pokémon. Powered by the same chip at the heart of the TI-84, the original Gameboy was a defining element of childhood for many 90's kids. Although ancient by todays standards, at the time it was nothing short of incredible.This project captures that nostalgia by faithfully recreating it in a novelty form factor.
Custom Built Raspbery-Pi based miniature Gameboy emulator. Emulator written for raspberry pi in C/C++. Project placed with screen and buttons into custom case. Target size is something small enough to be used as a functional keychain.
Project will split into two phases : software design of emulator and hardware design of the physical device.
