Intellimouse to trackball hack

isugoat:

anyone know the website to one?  specifically i'm looking for the soldering points to draw power from the intellimouse board.


thanks in advance

SirPeale:

Show me a pic of the PCB and likely I can show you the points.

isugoat:

no camera to take a picture of it...
was pretty sure i got the tutorial from here like 2 years ago, but search turns up nothing...and google didn't turn up anything relevant except one guy who had his intellimouse hacked but there was a cover on it in the picture and no explanation =/

I've just completed one, I used a two button ergo MS mouse and a Suzo ball from Ultimarc.

I've got some pics of the circuit board, just have to dig them up, label the points and resize them.

The 3-pin detector draws 5V from the middle pin, so I tapped the + & - wires from the x & y detectors, plus 5V from each detector. I also put 5V through a 2200ohm resistor (4 total) to each + & - signal lead to bring the trackball from active low to active high.

Blakey:

Here it is. I have more photos, and can take pics of the completed unit tonight if required. I used a 12 pin molex to connect the trackball and mouse board, the 12 pins went something like: x+, x-, gnd, +5v, y+, y-, +5v, gnd, LMB NO, gnd, RMB NO, gnd. with grounds split from the mouse grounds. On the trackball connector, two 2200ohm resistors went from each +5v to the x+, x-, y+, y- to pull up the signal.

Works a treat now.
