USB Iphone Ipod Dynamo Charger

Step 9 The final product & future plans:

Over all I would give this project fro a scale 1 to 5 (1 easy-5 hard) a 2. Over all this is the easiest Dynamo project that I have done. Build this project in a week end and save the world! Maybe not the world, but when you are in a pinch and need some power this product will come to your aid.

Testing:
-About 2 minutes of winding increases the power level on my iphone about 1%.

-If you iphone is dead, about 5 minutes of cranking will bring it back to life


Future plans:

Building a wind-up&solar charger to put in the window at work/home to charge my iphone off the grid. How novel! Having the phone that makes you the most connected but charges with no wire attached.

I plan on making one of these for my Nook so I can still access all my pdf text books on engineering, chemistry, biology etc during the zombie apocalypse. Also I'll get a solar charger too, but its not sunny all the time and I never know when I'll have to hide out underground. ;)

Could you make a windmill for this, like a wind-powered iPhone?
