Steve Caplin, Share Radio's technology editor, looks back at the early days of Wikipedia. He discusses two leaps forward in electric battery science, hopes for making night vision cameras smaller, the council that turned down £55m to find a hard drive, an app that failed to make a customised face mask and a smart bike light. He also looks at some of his favourite CES gizmos including a gamer's facemask, a vacuum that empties while charging, an ice-cream maker and a sat nav for the blind.
