Well, part of the appeal for me is figuring out the 'puzzle' and also saving money - I have not spent much on this and as KeithD it's great fun! Sorry for the lack of info - there is one set of black and red wires coming from each trackball axis. As for the leds - I haven't really thought that far ahead - I'm concentrating on just getting the trackball to work then I'll consider sorting that out. If you have any ideas as to where I should attach these red and black wires that would be great! Nice tip on the camera test too! Cheers :cheers: |

Where do the black/ red wires solder to on the trackball axes? Are they possibly the wires that power the IR LEDS on the axes? If so, then they would go across from where you have your brown/orange leads. Not sure how to ask this without being rude, but I don't mean to offend: Do you know how the mouse and trackball actually work? I mean the whole IR LED/ Optical sensor thing? K |

That's not being rude - I'm utterly clueless - I'm a fast learner and I tend to learn while I go along (perhaps this isn't always the best way but it has worked plenty of times for me before!) - I had used other people's examples to guide me but obviously they don't always fit exactly. Yes, from each axis you have one red, one black, one brown and one orange wire. The black wires always went to GND on the trackball encoder so I assumed these were ground wires while I'm not 100% where the red wires led but I'm positive it was a single point labelled '0'. On the actual axis boards the red and black wires appear to come from the same point which is marked '0'. The orange and brown wires on each axis are marked '3' for orange and '1' for brown. I'm assuming that the red wires power the IR LEDs while the black wires are just ground. My problem is, if I am right, where would I solder the red wires to the mouse encoder and where would I solder the ground wires? Thanks for your help. |

I'm thinking that if you were to plug the mouse into a computer and measure the voltage across the point where the LED was mounted to the mouse board, that would tel you which is positive and which is negative. For instance, if you were to have the red lead on the left, and the black on the right, and measured -3V, then you would have the red lead on the negative and the black on the positive. Swap them and you would have your red and black. figured out. Sounds like you might need to do a little research on how the mouse encoders work so that you can understand a little better exactly what it is you are trying to do. It looks like a hack that will work it is just a matter of getting it there. This explains it pretty well though a bit dated, and most mice up until recently only use the one sensor for each axis. http://computer.howstuffworks.com/mouse2.htm K |

Thanks for that - I was actually just taking a look at that guide! I'm starting to understand it a little better now! :cheers: |
