A few weeks ago I built the Dynamo Torch, but now I want to try and upgrade it to an functional flashlight of sorts if possible. I am unsure of how to do this at the moment though. I would think I would need to add a battery or capacitor of some sort to hold the charge from the winding of the hand crank.
If anyone has any idea's or finds some instructions on how to do this that would be great. I might just go pick up a hand cranking flashlight from Target and take that apart to see how it works and then do that. It kind of defeats the purpose of the build but I still think that I would be able to get something useful out of the project for me and the girls.
