I snapped pin7, which was my first solder, because the wire was too stiff. So I soldered to the stub of pin 7 and it works! I took apart a USB cable and used the wires from that for the internals. Also, I don't have the greatest soldering iron or the thinnest tip, but lots of flux helps the solder melt almost instantaneously. Also, I hold the assembly and wire together with clips and a single touch with the iron and solder at the same time completes my joint.
But I understand the frustration as my soldering iron has a rather large tip. I am probably going to buy the ZD 99 Solder Station
I also tried to solder a mini B USB receptacle so I could charge while using the LOD, but because of the size of the pins and my iron, I couldn't kept having 2 pins shorting, so I just pulled them off. With a Sansa cable with the board pined out for USB I think that would be much easier to implement.
Does anyone know where I can get an official Sansa Fuze cable, as I didn't see one on the Sansa site? Although I could just buy a Griffen Powerdock for $40.
