Introduction: Hand-crank Fan for Keeping Cool in the Summer
A fan made from a hand powered flashlight and an R/C helicopter. This fan provides a pleasant breeze to the user in exchange for some light cranking.
Step 1: The Flashlight
I unscrewed the screws on the outside and the ones under the cover (mentioned below)
I then removed all the circuitry, the upper casing , and the generator.
Step 2: The Helicopter
I removed the rotor from a Havok Heli (c), and cut off the shorter, weighted rotors, leaving just the main blades and the shaft.
Step 3: Putting It All Together
follow picture two very carefully, it is important that the rotor doesn't fall from the gear. :)
after the toothpick supports are in place, add more glue to the sides, where they touch the shaft.
