Step 2 Soldering on the Wiimote

Because I wanted all the buttons to be used I had do solder cables on the Wiimote board on every button. The only problem is, that the +, -, home, 1 and 2 buttons are small.
Just take the foil over them carefully away and thats it. I used a small cuter.
There is no best place to start with soldering but I thought it wouldn't be bad to start with the small buttons. To find out which side is the right to solder just take a Multimeter, use it in the contactmode (which means it beeps if the two tips have a conductive connection), hold on tip on one channel of the button and the other on another channel on a different button. When the Multimeter beeps it means that those channels are the ones you don't want to solder on. The have the voltage for the buttons on. Solder the cable on the other channel and to that with ever button. All buttons have the same source, so you can keep one tip on this channel and measure which you want to solder on. Don't forget to solder one thicker cable on one of the voltage channels. This will be the "source" cable, whick must go to every button!
I used ductape to keep the cables in place which was to secure them. What also helped me a lot was naming the cables by wrapping around some tape and write on it which button it is. You wanna do that because at the end there are hanging about 15 cables from the Wiimote. It's also helpful to make the cables longer than you can see on my fotos, because of the wiring, which comes later.

Oh, and what you definitively want to do is checking the soldering spots with your Voltmeter. I had a lot of fun taking everything apart because there were some cables not good soldered!!!
