Blackberry trackball question

[PspKicks316]

Are they digital or analog? Can they be converted to digital if they're not? Are they any good? Compare to a psp analog please.

These are the questions that keep me up at night.

that track ball is digital, it clicks when it rolls and makes a connection in that particular direction.

faster it rolls the faster it clicks.  So on that ball there are essentially 5 normally open switches... One for each direction(up, down, left, right) and one for center click. 

You may find that the clicks are too short to be very useful in gaming, might want to have a one shot 555 timer circuit on each direction in order to extend the time the switches are closed. In other words the click will trigger the 555 into sending a signal to the controller that is of the right length rather then short amount of time that the click makes a connection... srry if this is confusing.

It's okay, you helped me with it on MSN without you realizing it. I'm using those instead.

That 555 timer idea is good though.. I'll have to look into that.

Would the new crackberry laser pads work?

If I can find replacements online that are cheap, I would try it out with what I'm doing. That might be better, so long as they're still digital and such.
