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

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

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.

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.

ah cool thanks...i'll see if i can get it working from that.

Nice picture, but what is "the hole in the middle"?

The red one on the x+/X+?

If I wanted to use just the x/y, where does the power hook up?  Do I have to de-solder the left mouse button to find the ground?  I can't seee where the +5v is at in the pic.  Have a plan view labled?

I thought I made it perfectly clear when I said "The 3-pin detector draws 5V from the middle pin". So if you removed the detector you would have three holes. The 'hole in the middle' is thus 5V. Tap your 5V from there. Or if you're too scared, tap it off your power supply.

What is x+/X+? The red/yellow pair is x+/x- and the blue/green paid is y+/y-.

In case that still isn't clear enough have another picture:

Sorry, typo, ment X+/X-.  

That picture diagram makes it perfectly clear.  I understand now it's the middle pin in the detector group, either detector group.  Ground on the switch group.

I appreciate your quick response!
