Electronics modding enthusiast Anthony Thomas (via Reddit) was looking for a simple project to take on and noticed there were a lot of older Nintendo DS Lites missing their top screens. That’s bad for Nintendo DS games, but with all the hardware the DS needed to play Game Boy Advance and older cartridges, Thomas decided to grant them renewed purpose.

Using sheer electronic wizardry, Thomas figured out how to get the lower half of the DS to boot without the upper, then figured out how to do it correctly instead of simply adding a second power LED, because no one needs two power LEDs.
