Wico Trackball wiring.....

[Aceldamor]

Anybody here hacked a Wico 3" trackball for a mouse? I'm trying to figure out what which wires are the signal wires for each axis...

Any help would be greatly appreciated.


Thanks

[outcast_p]

are you wireing it into a mouse?

the black is ground, red is +5v

green and yellow are one of the axis, blue and purple are the other.

basically you just have to play with it to get it to the go the correct directions.

atleast that is what i did

Thanks Boba,

I actually found your site last night about 20 minutes after I posted that message. I did have one question though... On your site you have the molex connector from the mouse with the 5 volt in pin 1 and the ground in pin 2. The trackball its self is wired with the Ground in pin 1 and the 5 volt in pin 2. I'm no electrical engineer, but I wanted to verify that you actually crossed the ground and the 5 volt before I wired everything up.

You know after looking at what I originally posted, I must have been real damn tired! It wasn't very elequent, "what which wires"  Hello!!!  

[SirPoonga]

are oyu hacking ot a ps/2, ps/2 with usb adaptor, or usb mouse?

[Aceldamor]

I'm going to go ps2, since the trackball will act as my mouse.

Then you may want to get 5 volt power from somewhere else.  The ps2 port isn't the greatest power supply.  I got my 5v from a usb port.

I had a wico at one time.  black is groun, red is 5v.  Then you have colored pairs coming from each axis.  It's difficult to know which is which just by looking.  The harder part is knowing where to hook them up on the mouse, you may have a mouse with 3 or 4 pin IRs.  Anyway, once you find the right IR pins to hack to if the movement is backwards you just swap the two wires.

Thanks for pointing that out.  The second list is wrongly labeled.  The colors are correct.  Pin 1 Black Ground, Pin 2 Red 5VDC.

I did not want to wire to another point for the 5V since the mouse already had the 5V internaly.  No problems with running the trackball on the mouse PS2 plug for almost 2 years.

I will fix my site when I get a chance.

[SirPoonga]

well, you know which is ground and 5v because each axis share those wires.

[Aceldamor]

Holy lord is this a pain in the --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules--.

I bought a Logitech 2 button ps mouse and am having a beotch of a time figuring out what is what....

There are 5 wires from the ps2 cable to the circ. board.

Big black, Red, Orange, Black, Yellow.

The Emitters are 4 pin and both have 2 connections that go to the main chip, one goes to the orange wire and one goes to the red wire...

Can anybody provide some insight as to what could be what?

Any help would be greatly appreciated.

[SirPoonga]

My guess would be the two that go to the chip are the data stream pins.  The red or orange one is then the power.  Like I said, you might want to get power froma  more reliable 5v source.  the ps2 port can be odd.

[Aceldamor]

I thought the same....My guess is that Red is power also, but what is the orange? Ground?

I'm gonna check to see if I can get a wireing diagram of this mouse, but I'm not going to hold my breath...

*edit, no luck on finding any kind of wiring diagram....

[Aceldamor]

Sorry for extra post, but the edit didn't put this thread back at top..

[BobA]

Are you working with the emitters or receivers? The receivers are the components that are removed.  The emitters are just IR leds and do not need to be touched.

I figure out the wiring of the PS/2 mouse board by doing a continuity check of the wires to the plug since you can get a PS/2 plug pinout and reference which wire is which.

I ran into the same frustrations...my solution was to send Oscar some bucks for his USB mouse hack and Tball harness.  $9mouse-hack (12.50 for one with buttons)+ 8 for T ball harness.  

Saved me time and frustration.

[Aceldamor]

Just an update:

I got my trackball working and everything is cool, I just had a bad mouse the first time....

The actual hack wasn't difficult to do at all. You just got to be a little carefull with the solder. Especially around the pins for the ground and power. Since typically they are next to each other, you don't want the solder to touch.  

I got a little crazy on Crystal Castles, Centipede, Millipede, and The Irritating Maze this weekend. Marble madness got a little play also.

Which brings up my next question...Is there a standard list for recommended sensitivity settings for trackball games out there? Is this an instance where Analog + would be beneficial?

[SirPoonga]

No, probably because your sensitivity may be slightly different.
