Simple Socket USB Charger

So I sold my MintyBoost to a friend...
Here is what you need:
(1) Breadboard (this is just for prototyping, you can solder this all on a circuit board.)
(1) 5v wall adapter (I got mine as an old cellphone charger)
(1)Female Type A USB Socket
(2) 100k ohm Resitors (Brown Black Yellow)
(2) Jumper Wires (Solid core works best)
Optional
(6)Pin headers
(1)3mm LED (Indicator LED)
(1) 10k ohm Resistor(for the LED)

Hey I tried to make it but I didn't work. The light pops on but when I put my iPod in nothing happen. I tried my DS and that worked. I did every thing u said in the video.

@kphan000 Hey, sorry about your problem. My suggestion is to check that you have the right resistor values. iPods only work with 100k resistors, it's how they are built

[dofmann1]

Is it important to use 100 Ohm resistors or can you also just connect the positive with the usb pins?

[fruitkid101]

@dofmann1 100k resistors are only required for charging iPods

It also works with two 47k ohm resistors on the data lines and i think it works better with the 47k ohms resistors

Thank you so much! :)

I got the same setup without the led. The only thing I added was a 100k resistor between the data pins and it works fine. Is this ok?

[shadoskill]

I thaught you had to have the resistors on the positive side?

[kphan000]

I have 100k 1/2 watts. I tried that first it's brown black yellow. Then I tried 100k 1/4 watts and that didnt work ether (they were also brown black yellow.

@sapex72 no a 9v has 9 volts so it would burn out resistors or your divice
