Our Device
• Used Lego® to construct rotating parts• Manila folder as tube• 3 different sizes of copper wire• Ceramic magnets• Sperry Box as base• Model airplane blade as propeller• Hot Glue/Super Glue/Electric Tape used to
attach materials
Mechanical and Electrical Aspects• Magnets are attached to
a spinning rod• Propeller spins the rod– Propeller converts the
translational motion of the wind created by the fan to rotational motion
• Four grey Lego rods keep the coil and the rod in place
• Soldered together wire of multiple sizes

Design / Construction Issues• Majority of wire got
tangled• Difficulty finding good
wire/magnets• Issues creating a good
coil• Magnets were
orientated incorrectly• Issues with creating a
stable base allowing for the maximum speed/efficiency of our fan
