Mouse hack - 4 legged sensor?!?

(1/2) > >>

Hello,

I ordered a pile of USB ball mice for hacking, and it hasn't gone as smoothly as I might have hoped.

SirPeale:
Can you get a better picture of the top and bottom?  Use the close-up setting on your camera, it's usually denoted with what looks like a small flower.

looks like one of them (the top left) isn't connected to anything

It may be on the top.  Thru hole soldering is a pain.  That's why I wanted clearer pics.

That's right - all of the legs a connected.  Some on the top surface of the circuit board and some on the bottom.  I will post more pictures tonight.
