Modifying the Steam Deck into a compact, mobile, AR gaming device. Not endorsed or supported by Valve and is likely to brick your device... - crastinator-pro/steam-brick
It’s really amazing how much power you can get for cheap in a small package these days. But yeah putting a battery on that wouldn’t be practical, it’s still a very efficient chip, but in absolute terms eats a bunch of power. So you’d need to be tethered. You could easily wear one of those mini pcs, but need a power cable. One of those could be dropped down from the ceiling, but still not as good as a mobile solution.
