[DIY] Hand Crank Powered iPod shuffle Charger
Tuesday, May 17, 2005
Reader Craig brought this nifty hand powered charger hack to out attention. It is by one of our favorite blogger/hackers Phillip Torrone over at Make. Phillip writes:
Okay, this is what my friends call a "Torronesque" project. This is where I usually come up with something and build it, and it really has no purpose or usefulness- but on further inspection it's kinda neat. This is the iPod shuffle hand charger, actually recharger. There are many "crank powered" accessories floating around, so I thought I'd try a few and figure out if the iPod shuffle can be recharged with one. Well, it can, sorta. Here it is in action! I am still working out the best voltage regulator and wiring, as I figure it out, I'll post the details, I don't what to screw up everyone's shuffles. What I'd really like to do is add little power generating motors to more things. Imagine getting a little power charge everytime you press a key or open your or phone laptop, maybe it wouldn't matter that much, but multiply that by a billion people and perhaps it would...

It might work even better if you put a capacitor inbetween the crank generator and your shuffle. You could crank it for a while and take a break and it would keep charging. It would also prevent spikes in voltage if you cranked to fast. I have no idea what size of capacitor you would need though.
Please post an announcement as soon as your underwater version is up and running and I will take it in the pool. Thanx
haha to what 1st anonymous said: putting in a capacitor wouldn't help because it'll discharge as soon as you stop cranking... unless you're good with 1 micro second breaks =P
cool idea, but newegg has a commercial crank generator on sale for $21, and supplies for this project will probably total to that amount.
