Portable video games continue to get smaller. One developer known as c.Invent has created what he’s calling a Keymu — a miniature Game Boy that fits on a keychain. The mini video game console was inspired by a project from the Hackaday Superconference last year. Stuffed inside Keymu’s 3D printed case are an Intel Edison, a 1.5-inch OLED display, a 11.7mm speaker, and a 220 mAh lithium battery. Keymu is believed to be world’s smallest emulation console at 42 x 46 x 17mm. It resembles the Game Boy Advance SP, but has four control buttons opposed to the Advance SP’s two.
“Have you ever dreamed of having a keychain allowing you to play your favorite NES, SNES or GBA games?” the developer wrote on the Keymu Hackaday page. “Well neither did I until Sprite_TM completely won my heart last year with such a cute, impressive and useless little wonder, as I sincerely hope Keymu will win yours.”
