 see top one says Translucent but bottom one says Translucent and Illuminated.

what's the difference between these two?

[allroy1975]

the bottom one is illuminated.

it comes with a tiny lightbulb that isn't very bright.  get that one...because for some reason it's like $2 cheaper, then get some LEDs to put under it to light it well.

Dear Lord, don't buy either one of those.  Happ is raping you.

Buy a 3" Happ trackball from Happ here for $53.99:

(Or see if Ponyboy can get you a better deal.)

Buy a replacement ball from Happ for $33.00:
http://www.happcontrols.com/trackballs/950029xx.htm $33.30
(Or see if Ponyboy can get you a better deal.  I think Bob Roberts also has them, and a lot of folks have bought translucent 3" juggling balls, too.)

Buy GroovyGameGear's new optical encoder board when it becomes available (soon) for $16.95
(Or hack a cheap mouse.)

Even if you Buy the Happ ball and the GroovyGameGear encoder, you've only spent $104.24, leaving you $52.46 to light the thing up with.  Or buy a spinner, which the GGG board should support, and the Happ interface won't.

The only difference between the trackball assembly I linked and the one you're looking at is that it has a higher "lip" of plastic around the trackball hole.  Which is designed to push up through your control panel / plexiglass / lexan, but you can just sand the lip right off if you don't want it.  Mechanically and electrically, they're identical.


edit- electrically, they are not identical, maybe.  The Happ diagrams show a different part # for the optic boards for these two balls.  Whether they actually ship with two different boards, I don't know, the exploded diagram for the standard 3" may just be out of date, or it may actually ship with a different board.

if i were to get that would i need a differnt mounting plate? because my control pannel is wood.

[divemaster127]

The mounting plate you want is the 3" happ mounting kit, i have a dozen of these in stock they mount to wood & i sell them for 10.99 each & they come with the screws you need & look really good
thanks
