for some reason this wnt charge my ipone 3g and every thing is wired correctly even the light turns on.

will this work for the ipod touch 3g?

Just a word of advice to any of you who plan to use that circuit for anything of worth, dont! its not safe enough to charge them with out frying them over time. I have posted one that is basically the same, with some capacitors used as filters, the 330 ohm resistor can be anywhere between 100 and 330 ohms, and the 15k, can but substituted with a 10k, havent tried anything in between!

the resistor should be a 220(u)-1k(u) the 220(u) color code is a red, red, brown, gold or silver(tolerance) and the 1k(u) is brown, black, red, gold or silver. the perfected one would be thee 220(u) range. the one showed in the picture is a 10(u) resistor and it would burn out the ipod because the voltage would be to high. ~~~binary_man_1010~~~

when ever i made the charger and i plugged my sisters ipod nano 3g in it turned on the ipod on but it didnt charge it and when ever i put my ipod touch 3g into it it did not do anything.  i was wondering if it was beacuse the new ipod touchs are like the iphone and i need to change the wiring.  also i used a 10 ohm resistor, is this to much or too little? someone help!!!

actually giving less voltage to the regulator by adding the resistor in front might be beneficial so that the regulator does not heat up as much. This works if you are sending more than 5v out of the resistor otherwise it is pointless and agree with bomberman 3 on his circuit. In addition this will not charge your iphone. for the iphone to charge you will need to use pins 2,3 on the usb with a +2.7volts and -2.7 volts in addition to 5 volts on 1,4. Good Luck People : )

what kind of resistor do yiou need to make the device?

i have a video nano and when i plug it in it lights up but does not charge, I thought that the ipod cables were wired different, mabe not ge back to me please

I made this and used it on a usb light and the led flashed then went away it is not the bulb being burnt out because i can do it again also i nave nano 3g it lights up but no charging.i tried an enV 3 it sais charger not reccomended but starts to charge.

It's a cool charger, i used this mainly to figure out how to wire up the regulator. I found that the regulator get's warm, I haven't had it on for a long time yet, so I don't know how hot it gets, but I would reccomend a heatsink for the regulator.

Thanks Binary Man, you could have just saved my ipod

That pic is awesome!. Great instructable too.

I forgot to put the resistor in and when i tried it the light bulb blow out so fast but it was very bright next time i am going to video tape it. It was pretty cool!

were can i get a female usb port

Here is just a better schematic and a few notes about the charger. Required Parts: 1) Toggle Switch – Single Pull Single Throw 1) LED 1) 150 Ohm Resistor (Brown, Green, Brown, Gold) 1) Radio Shack 7805 Voltage Regulator + 5 Volt dc 1) USB Female Cable End Purpose: Toggle Switch – to turn on the charger LED – to indicate the status of the charger (On or Off) 150-Ohm resistor – used to limit the current through the LED and the Voltage Regulator Voltage Regulator – to regulate the output voltage to +5V dc Notes: There is approximately a 1.7 voltage drop across the LED There is approximately a 0.6 voltage drop across the resistor This leaves approximately 6.7 volts entering the regulator The switch, LED, and resistor may be placed in any order because they are in series with each other. All three must be placed between the positive side of the battery, and the input side of the voltage regulator. (A higher resistor value drops the output voltage below the +5V dc output. For example, a 200-Ohm resistor reduces the output to 4.9V dc)
