Virtual reality promises all kinds of things, but one thing it can certainly do is make those boring indoor training rides on a bike a little more fun. DIYer Paul Yan shares his system.
Yan's system uses an Arduino to track the rotations of a wheel, then a cheap headset for an iPhone, and a cheap virtual environment from Unity. It certainly leaves a lot to be desired in the actual environment exploration, but the rest of the system seems solid enough. Just make sure you figure out a way to not sweat all over that headset. Head over to Yan's site for all the details.
