Fan Powered Jet Boat

thingiverse

I took Keye's Balloon Boat project and gave it a thrilling twist by turning it into a fan-powered jet boat. Out went the balloon, and in came a powerful 30x30mm fan, two AAA batteries, and a clever small circuit board that ramps up the 3v battery power to 5v, giving the fan the speed needed to propel the boat. I secured the fan firmly in place with glue and plugged its screw holes with Blu Tack to make sure all the air generated by the fan flows downwards, powering the boat forward. For a captain to navigate this high-speed vessel, I left two Lego pins at the bow of the boat. Big thanks also go out to mrbenbritton for providing me with the battery holders used in this project - check them out on Thingiverse: https://www.thingiverse.com/thing:119847
