Rubber Band Gear Mechanism
Description
Conceived as a power source for future projects the Gear Mechanism stores and releases rotational energy in rubber bands. The amount of energy stored is dependent on the number of rubber bands used.

Independent of the function of the spur gear assembly, the final rubber band mechanism looks to be some sort of detent.
I'm Glad everyone like the Rubber Band Gear Mechanism. I'll get the assembly instructions online in the next day.
Sorry about the delay, real life interrupted.
Love this thing... Also, it looks like an upside down cuttlefish for extra awesome.
what is the transmission ratio from the handle to the gear with the rubber bands?
Very, very nice work. I think this will become the basis of many derivatives. 8-)
Ooh I think I may update a lot of my rubber band models with ideas you used here. Would you be interested collaborating on some stuff? Nice job.
THIS--- this is sixteen flavors of rainbow hued amazingness.
On fire.
Now THAT is freaking awesome...!
Guess it may need a governor in the future to measure the delivery of energy?
If I remember right a 1m pendulum swings in a very practical 1sec. pendulums gotta be the key to printable clocks.
:-D
Immediately thought of this educational video with some music: http://www.youtube.com/watch?v...
a makerbotted clock would make an insanely cool thing to have/give away/study/modify/...
but a governor dosen't rock back and forth, it has 2 weights on arms that, when swung out, hit something, and activate a brake or something.
Next, you need to make a clock that uses this!
Nice idea. I wouldn't say the mechanical efficiency of the printed gears can be expected to be very high but it would be a matter of adding the pendulum and scape mechanism to this thing and a bit of magic to get the first attempt to make a printable clock.
Excellent idea! That will be awesome to see a printable clock that is wall mountable. :-$

IF you added a heavy disk to the crank handle, when you released it the force applied to the greater mass should cause the rubberbands to reload. This would cause it to spin down and retorque until all of the potential energy translated out of the device. This creates a kind mechanical alternating current.
To rectify that into a single direction see:
