Can anyone take a picture of wires attached (soldered) to the little circuit board? My wires have broken off and I need to resolder them, but I don't know where the colors go (except for black which is the ground). Email me a color picture at [email protected]

Circuit board
Can anyone generate a schematic of what's on the little circuit board?
We might be able to construct a circuit so as to use a standard USB cable.

This **** ^, I use it when I'm doing wiring on my car, I like it more than liquid electrical tape.
I just had my first replacement cable bend pretty severely, but it is currently still working. I may give the epoxy method a try on this cable to keep it from breaking completely. So, I may have luck getting another replacement cable? I thought this replacement was the only one I could get. My first one stopped working on the second day I had it, and it didn't even get bent that I could tell.
I find my LG charger to work very well... charges my NC while I sleep. I always wake up with a full battery and listen to music all day. Rinse and repeat process, though most of the time I only need to charge every 2-3 days.
Circuit board pics/schematics
Do you guys still want or need a picture and schematic? I have a picture of the circuit board, taken through a low power microscope. The picture I have is without the connector end of the plug, since it was broken off, but I have determined which pins go where on the plug. I have been working on putting the schematic together on some free software, but the software is somewhat limited, so it's giving me some problems. I'll have it soon though, it's not a complicated circuit by any means. Lol

Here is my picture of circuit board. The contact side of the pins that fit the NC connector would be facing downward on the right. Sorry if it's not quite as clear as it should be. It was difficult to line the camera up exactly by hand. Also, some of the plastic has been cut away near where the pins have broken in order to get a better contact with my multimeter to follow the traces on the board. My schematic is almost finished, and will follow soon.

After viewing the photo, I think the availability of those SM devices would be limited. The solution is probably a charger from another device. The voltage regulator/current limiter wouldn't be there. It probably acts like a trickle charger, varying the charge time.
The ultimate solution is Nook redesigning the whole thing!

Chuckb38, I agree with your statement. Nevertheless, here is the schematic I was working on. I laid the components out as they appear on the board.
A couple things to note, the app I used to create it did not have LED symbols or mosfet transistor symbols, so I used what was available.
The two diodes labeled D1 are actually one dual color LED with three contact points.
The transistor Q1 is a Unisonic Technologies UK3018 N-Channel Mosfet. The dataset can be found on Unisonic's Web Site at unisonic.com.tw

For those of us who are less adept at circuits, etc, I bought a stock USB charger and charge through my computer, not the wall. It works well enough. Just make sure that the Nook's screen is off when charging, or it drains faster than it charges >.>

Looking at your schematic, it seems that pin 4 and pin 9 act like a trigger to identify the cable. If we could only find the connector through mouser or digikey...
One thing that I have done to help keep the cable in good health was to encase the plug (minus connector) in a resin block. When I first plugged the cable into my nook, I was uncomfortable with the stress that the cable was under if the nook was resting a flat surface. I made sure that the block brought the connector up to the same level as the nook's connector (no more stress at the port ^.^), as well as reinforce the exterior of the plug.

Thanks very much for the schematic! Looks like more trouble than it's worth, unless you are really into this type of fabrication.
I just checked the B&N online site and they list the cable and charger as no longer available. Am I looking in the wrong spot?. Never mind seems if you follow one link it shows no longer in stock another shows them as being in stock.
Found out it depends on which link you follow, one says out of stock, the other tells you they are in stock.
