Homage to duchamp's bicycle wheel - a dual mode led lamp (DC hub generator or AC plugin)

Picture of homage to duchamp's bicycle wheel - a dual mode led lamp (DC hub generator or AC plugin)
In honor of the 100th year of  Marcel Duchamp's most famous "ready made" creation, the bicycle wheel lamp and generator.

This is  a dual mode led lamp  for plugging in an AC LED bulb or spin it yourself for powering DC LEDs (with battery backup.)  Choose the  green option with Cree's latest LED 9.5 watt light bulb or go greenest with your own power.  And be prepared for electric outages by spinning the updated duchamp bike wheel with its electric hub motor wheel.  As the wheel spins it generates and stores electricity in a battery underneath the seat.   Flip the DC switch and the battery powers 3 x 2 watt leds at the base of the lamp.

Materials -
Hub motor & wheel - look on craigslist / any used bicycle electric assist hub motor should work, (this was a used golden motor mini)
http://www.goldenmotor.com/  - the most common failure for hub motors are broken hall effect wires.  As a hub motor used for a generator does not need the hall effect wires, you can often pick up a used hub motor very inexpensively.  

hub motor controller - virtually all bicycle hub motors are DC brushless. They come with a controller box which includes use a bridge rectifier.  The controller will use the  bridge rectifier (when you manually spin the motor)  to convert your work to DC voltage which will charge a battery pack.  Any used DC brushless electric bicycle hub controller should work.  craigslist or http://www.goldenmotor.com or ebikes.ca
