Introduction: Simple USB Socket Charger!
Most of us have iPods or cameras. This is instructable will show you How to make a wall adapter for them. Normally it would cost $30 at the Apple store but I had all the components in my spare parts bin. For me it was free! IF YOU SOMEHOW MESS UP WHILE BUILDING THIS AND
SOMETHING BAD HAPPENS TO YOUR USB DEVICE, I AM NOT TO BLAME... Just had to say that. Oh, and watch the video too!
Step 1: Video!
Step 2: Parts
Okay This is really simple, Here is a list of all the Parts that 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)
Step 3: Schematic
If you know how to read a schematic, here it is. I won't go over how to read them since there are many great tutorials on how this is done. I've documented this well enough that you don't need to be able to read them. So if you don't, just skip this step and keep reading!
Step 4: Putting It All Together (Power)
Okay I'm going to do this on a breadboard for simplicity but of course you can solder it all together. My instructions here may differ from those on my video. Breadboards have Numbers and Letters on them like a graph, I will use this to tell you where everything goes.
I soldered pin headers to the ends of my USB and my 5v phone charger.
Take the -5v from your phone charger and plug it into J4
Take the +5v and plug into J2
Step 5: Indicator LED
I soldered my 10k ohm resistor directly onto the LED.
The negative end (usually marked by a flat spot on the side) into I4
Plug the positive side into I2
Step 6: Jumpers
Okay, Jumper wires allow electricity to flow or "jump" to other parts on the breadboard.
Take one of your jumper wires and connect it between F4 and E4
Then take your other jumper and use it to connect it to H2 and B1
Step 7: Resistors!
Okay The 100k (Brown Black Yellow) ohm resistors are for the data lines. They tell the USB Device that it is okay to draw power from this source. You MUST use 100k resistors for iPods. If you aren't using this for an iPod you can probably omit this step.
Connect on from F2 to D2
Connect the other from G2 to D3
Step 8: USB
I soldered pin Headers to my usb port.
Plug the USB to the other Side of the breadboard It should take up A1, A2, A3, and A4.
Make sure that the USB Jack faces outward just like in the picture. Otherwise you may damage your USB Device.
Step 9: All Together!
This is how it should look like when all the components are placed. The iPod is charging!

Hi great project, does it works with the knew ios update

can we attach a 6v 120mA solar panel to it and make it a "solar usb phone charger" ?

i have a wall adapter 5 V 500 mA that doesnt work... all battery charger instructables didn't work for me! it's very frustrating!!

Here is my setup, it's just a draft.
the resistors for data pins are 100k ohm, for the led is 10k ohm, the connector at the bottom left is for a nokia phone charger which delivers 5 v @ 360mA.
If I connect it to a usb hub, all the lights light up like if it were connected to the pc, but if I connect it to the ipod nothing works :(

Make sure that it is hooked up like this
Reply 13 years ago on Step 9
yep, it is.
I'm still thinking it has something to do with the phone charger giving 360mA instead of 500mA :(

did you see any battery with 5 V input?
thank yoU! :)

for resistors in series the value would be
R1 + R2 + R3 +... = R(total)
for resistors in parallel the value would be
1/R1 + 1/R2 + 1/R3 + .... = 1/R(total)
or
(1 / (1/R1 + 1/R2 + 1/R3 + ....) = R(total)

Does this charge a 4th generation ipod touch? cause i've tried others that don't work with my ipod

can we we connect it to a notebook cooling pad
Reply 11 years ago on Introduction
You can connect it to anything that gets power via usb

instead of a wall plug could i use a 9 volt battery hooked up to a 5 volt regulater?
Reply 11 years ago on Introduction
Yes indeed, there are many instructables for that out here
11 years ago on Introduction
also, do you really need the led?
Reply 11 years ago on Introduction
Nope, not at all. It just helps sometimes.

The schematic in step 3 has an error in it. Refer to these pictures, and the corrected schematic here...

I thought pin 4 was meant to be ground...
Reply 12 years ago on Step 3
I agree...pin 4 is ground.
I believe that this is actually born out in the pictures in the ensuing steps. You can see that pin 4 is at the "bottom" in the picture of the USB connector. The photos appear to be the rotated reverse of the schematic...with the ground/negative side of the circuit at the bottom rather than at the top.
