DIY Ipod/USB power charger for under $30 (from DCoT)
from Daily Cup of Tech..."I have to admit that I have never owned an iPod. In fact, up until last night, I have never even touched one. So, when I buddy of mine called me up and asked if I had a USB power charger, I said sure, not realizing that he needed it for his daughter Tessa’s iPod Nano for their vacation.
When they got to my house, I quickly realized I had the wrong adapter. In fact, the connector was like nothing I had ever seen before so I knew that I had nothing to help them out. Then, a thought came to me. I told them to give me a moment while I ran downstairs to my lab (Yes, I have a lab in my basement! No Igor jokes! He gets mad!).
A minute later, I emerged with a homemade iPod Nano charger with the ability to charge up to four iPod Nano’s at the same time! Actually, all I had was a powered USB hub but it was exactly what the doctor ordered.
Now, you could go and buy the iPod charger for $40 or bring a laptop with you but this solution has a number of advantages going for it:
1. You can charge more than one device at a time
2. Can usually get a powered USB hub for under $30
3. Still works as a great USB hub
4. Can charge other things than just the iPod Nano
5. Smaller than a laptop
6. More readily available than the iPod Nano charger (you may even have on lying around at home)
If you are going to do this and you want to buy a USB hub, make sure that it is a powered hub. Bus powered hubs will not work because they get their power from a computer and this would defeat the purpose.
If this idea did not work, my next course of action would have been to build a 9 volt battery USB charger. But, that would have taken me at least five minutes to make!"
