HELP - Trackball Soldering / Mouse Encoder - Hack Advice Needed! WITH PHOTOS
<< < (5/7) > >>

You may be right - but whats reassuring are these 2 articles I came across -

Okay, it has arrived today (not the PS adapter but all 4 trackballs!) - I'm assuming that they won't work with the adapter anyway as the instruction manual does indeed say that these will only work with PS Mouse games.

I've taken it apart and it follows very similar to Betson Imperial 3" trackball found here -

It has red wires coming from each axis which I guess are both soldered to the same point as the red wire on the mouse encoder shown on this page (yes, I have got a Microsoft PS/2 Mouse spare), it has one black wire (ground), again which can be soldered to the same place shown in the photos and it has orange and brown wires coming from each axis which I would have thought have to be positioned where the opto-transistor output pins are (refer to the photos on the website again).

Does this sound right? I may take some photos of the inside of this thing and post them up as this isn't my forte and I could really do with some opinions!
slapaham:
So here's some photoes -







Any thoughts? If more photos are needed, let me know, such as the underside of the circuit board or more pictures of the right circuit board - I didn't regard these as all that important and I'm really not fussed about getting functionality out of the turbo switch or the 2 sets of L and R buttons - removing the existing encoders would remove these entirely from the casing anyway!
Turnarcades:
Looks pretty straightforward wiring-wise, but it depends how the encoder boards interpret the info as to wether it will work on a PC. From what I understand it may not, but I'm not that technical minded so I'm probably wrong.
KeithD:
I think I would look at replacing the insides with a mouse, depending on how you would want to interface to the computer. See if you can pop the optos and emitters from the mouse right onto the boards for the optos in the trackball, and replace the encoder board with the mouse board.

Either that, or see if the emitters and optos in the trackball will connect to the mouse board. There is less soldering that way. If the sensors in the trackball are compatible with the mouse, then what, 10 wires to solder and off you go? Nice!
