Getting stuck on a flat portion of a trail while snowboarding is a major buzz kill. You can either hop yourself to the nearest slight downhill or unstrap your board and take a walk. Neither option is fun. [Jude] was tired of getting stuck on the flats so he strapped an electric ducted fan to the back of his snowboard.
The powerplant is an Electric Ducted Fan (EDF) intended for RC Aircraft. It is supported on the snowboard by a 3D printed mount. [Jude] made his mount design available for anyone interested in following his lead. Good ole glue holds the fan to the mount and the mount to the snowboard.
The battery is a 12S, which means it has 12 LiPo cells, 3.7 vdc each, wired in series to put out 44.4 volts. Inbetween the battery and brushless motor in the EDF is an Electronic Speed Control (ESC) that is normally used for RC vehicles. [Jude] purchased an ultra-cheap RC transmitter and receiver setup to give him one-handed wireless control of the fan’s speed. He estimates he can hit 15 mph on flat ground. If nothing else, it looks darn fun to ride!
