Nintendo’s classic Game Boy has long been the darling queen of the handheld scene. However, with many fans modifying their handhelds with power-sucking features like modern backlit LCDs, running on AA batteries can become a frustrating exercise as they rapidly run out. [esotericsean] gets around that by modifying his Game Boys with a USB rechargeable battery setup. (Video, embedded below.)
The hack is a simple one, but the execution is quite tidy. [esotericsean] starts by removing the original DC jack from the Game Boy motherboard, and hogs out the hole in the case to fit a micro USB port. The original battery housing is similarly carved out to suit a 2000 mAh lithium-polymer pouch cell. A single-cell charging board is used to manage the battery, with its original connector removed and replaced with a neater-looking panel mount micro USB port instead. The electronics is then wrapped up in Kapton tape and stuffed inside the shell as everything is put back together.
