MAKE: television Episode 7: Urban Projections & Wind Generator

Bike along with Ali Momeni and his fleet of mobile video projectors that transform public spaces into massive sound and light shows. In the Workshop, John Park combines a used treadmill motor and PVC pipe to build a wind generator, and William Gurstelle tests hardware on a giant trebuchet. The Maker Channel features a balloon organ, a ball-fetching autonomous robot, and a lie-detector wristband.

    Love the show!! love the wind generator,very creative!! one suggestion,to get a true and useful output measurement,it should be in watts,not volts.I’m not critisizing,just a suggestion.I’m not able to tell what it would be useable for without a wattage rating.Thanks and keep up the great ideas!!!!,Don

    Say we can’t find a 260VDC treadmill motor but rather a 130VDC, how should we change our plans to accommodate?

    the treadmill motor flywheel is 19 inches round so what will that be evenly spaced 3 times , thanks for your help

    1. Vinnie Dontinelli says:

      That would be 6 1/3″, but use a protractor and make it 120 degrees between each one.

  8. Judd Reese says:

    I would love to know the tread mill you got the motor from or the model # and mfg of the motor.

  9. Vinnie Dontinelli says:

    What RPM is best for this? I have some DC motors. Treadmill motor I have is 4460 RPM. This seems too fast – would never turn fast enough to produce power. What RPM is optimal??
