I plan on being away from the house for a while this summer with my iPod, so I decided to build an emergency battery charger for it. Here are some pics of the completed project:

Power on! The LED light is lit up:

Nice idea! :)

Hmm... The iPod is meant to be charged by the USB port (or a power supply), meaning its output voltage is to be 5V. You're using a 9V battery. Did you do some current transformation? I'd not feel good if I knew I was charging my iPod's battery with too much voltage, this will damage the battery. .

Im guessing he used a resistor of some sort.

EDIT: Image 3, you can see a resistor, so yes, he did use one.

By the way do you know a 9v battery won't last long? You'd be better off with AA batteries instead.

I could have used AAs I guess... but I don't really feel like changing it now.

BTW, I got the parts (battery snap, usb connecter) from this site: electroidsco.com

The best approach (IMHO) would be those 4.5 V flashlight things, but those may be harder to come by compared to 9 V.

I used a 4.5 V converter hooked up to a USB extender cable I dismantled to make a generic USB charger, similar in concept to yours, but yours is slicker and more portable.

In case you didn't see it above, you can get a kit from electroidsco.com with instructions and all... it worked perfect for a semi-beginner like me. Also, I am considering buying a rechargeable 9V battery or two to save money.

Rechargable 9v batteries has significantly less power in them than a non-rechargeable battery. Lets say a non rechargable battery has 500mAh of power, and a rechargeable has 200mAh of power. You can see the difference. I also understand that neither battery will fully charge an iPod anyway. There isn't enough power in one charge to do so.

Yep. I know. I won' be using rechargeables. I think the ipod's battery is around 750mAh. Therefore, I'm pretty sure that the single non-rechargeable 9V could give me 4-6 extra hours of music playback at a low to medium volume, though.

You should get one of those little solar chargers :) Music wherever there is sun :)

I really don't know enough about solar energy to do that...


Would I just connect it to the regulator like I did the battery?
Could I use the battery while I have the solar panel connected (in dark rooms, ect)?

No, you get a solar charger commercially as they need better circuitry to keep the voltage at 5v. Alternativly you could buy a 6v panel, a 6v battery and a lower size resistor to make it 5v again and use that.

Solar complicates things but its so much fun if you enjoy a challege. When there is sun, it uses the panel, when there isnt it'll use the battery. When there is sun and you're not using the iPod it'll charge the battery :)

Where would I find a solar panel? At RadioShack, another store, or online? Also, it would have to be a 6V rechargeable battery, right?

You can find them in all sorts of places these days, just shop around. Look for no higher than $5/watt otherwise you're being ripped off.

If you get a 6v panel it would have to be a 6v battery. 12v panel, 12v battery etc. Unfortunately 9v panels don't exist commercially. You can buy the cells and make your own. The educational ones that just clip together might be ok.

Like I say, if you want to experiment with solar, you need to know how they work. Otherwise stick with simple :)

I can help you out if you need it. I have a 42w solar system set up at home to run lights and occasionally my laptop.

Okay. Thanks for offering to help. I think I might take you up on that offer once I have some cash to spare (saving up for a laptop).

Ah cool. Let me know what specs you end up with and the price. Im after a new pc myself, but with no job, just $80 a week coming in (and thats soon to end), thats going to be hard. As soon as I get a job I'll have a car to run, lodging to pay and also saving for stuff I want! It'll be hard.
