Shake-em-up flashlight generator
nightlife:
Are there wind up generators that wind up in both directions?
As far as switches, I like the light activated ones because they dont create a drag on the motion of the motor.

No.. your not crazy Stefan..lol
Instead of shake-lights...Be-ware of Fake-lights..
Yup there's some rip-o f f shake flashlights out there !.... I got a shake flash light and it was totally fake.
(1) The coil was connected to nothing...the magnet was no magnet.. just a cylinder piece of metal...one resister, no diodes...
It was nothing more than two round flat batteries ran through a switch to the l.e.d. ....lol
(2) Another light I got that was fake.. Had a hand trigger type lever..which spun a motor inside for charging.
Like this one: http://www.auctiva.com/hostedimages/showimage.aspx?gid=241145&image=48837432&images=48837432,48837438,83574396&formats=0,0,0&format=0
and Again.. contained two batteries, ,a resister, a switch , and two l.e.d.'s... no diodes.
Although, This one did actually have the coil connected to the led's which would light up when you gave it a crank.
but of course, contained no rechargeable batteries. nor wired up to even charge a battery...
Actually works good after you add a re-chargeable battery and wire it up. lol
So both of those flashlights contained two round 3Volt batteries.
Equaling 6volts. which will power the l.e.d. plenty long enough until you loose the flash light.
and the average joe is the none the wiser. and still thinks the cranking and shaking is charging up his flashlight.
Look at your shake light.. I bet it has two round 3v NON rechargeable batteries. They All do! L-O-L
