Hey /diy/. I was originally thinking of adding a friction drive to my bike for those times i'm feeling lazy. But I like my bike the way it is, so, how feasible is it to build one of these (specifically replicating that one wheeled hoverboard) and not have it be a gigantic deathtrap? There's some instructables that use arduino so it seems like it's at least possible? I get that for it balancing from front-back, but how about side to side? Also, IIRC the hoverboard pictured charges its batteries insanely fast (they're a lithium cell array, charges in like 15-20 minutes). How would I charge say a bunch of 18650 lithiums fast without it turning into the fourth of july?

Liquid electrolyte lithium-ion round cells may be tempting for their somewhat better energy density, but if you're gonna push the charge rate past 1C/<1hr then you're probably better off with LiPoly batteries instead. I'm not saying charging round cells at 3-4C can't be done, but you're kinda in uncharted territory there.

Source? Motor? The hardest part is finding a motor that can be mounted, be balanced, and within spec. I don't know what kind of motor that is, but I'll take 10 for all my various projects.

Why does it have a wheel if it can hover?

here's one of the one-wheel ones I've seen. Alibaba has a bunch of knockoffs of the one in my original post, but if I ordered one it would be just to recycle the wheel and case, I don't want to catch fire.

For when it lands, same reason why airplanes have wheels and they can fly.
