Step 11A Few More Things To Wire
In this step, there are just a couple more things to wire up.
The MP3 player comes with a male USB soldered to the circuit board. I got a female USB connection from a USB hub I picked up from Goodwill - it had 4 female USB connections!
I marked on the male USB and circuit board before desoldering.
Plug in the female USB to the male for reference.
Desolder the male USB, loosen the holding tabs and remove.
*Important! - To make the connection properly, do not rotate the USB to connect the female USB, instead, flip it over. The female connections will appear upside down, but this will keep the contacts lined up properly. Worst case scenario, you device will not be recognized by your computer and you will have to desolder the USB and fix it.
Use a ribbon cable, 4 wires, use a length of 3" or so. Solder the MP3 circuit board to the upside down female USB.
Solder the positive and negative battery leads to the circuit boards.
CAREFULLY desolder the headphone jack!!!! I have ruined 2 MP3 players at this point. If you force it, you will tear the solder pad off the circuit board. Remove as much solder as you can. I ended up using a micro screwdriver to incrementally lift the jack in very small stages by heating up a solder point while applying light pressure, then moving to another point and repeating. It takes 8-10 small movements to free it from the circuit board.

You can definitely tell which era the circuit boards are from, and which is which!
