Trackball with smallest footprint?

[Stormy151]

I am considering building a mini/bartop cabinet for my niece, and would like to have a joystick, spinner, and trackball on the CP.  I plan to base the size of the CP off the size of the trackball, since it will take up the most real estate under the panel.

What's the smallest footprint 2 1/4 trackball availiable?  Or are they all about the same?

I have used a happs and a wico/ultimarc and they seem to be the same footprint.  If you've got big $$$ there is a smaller option:

if you want the smallest footprint available, you may not want a 2.25" ball.  I think it would be safe to assume that they have the same footprint.  I have a wico command control trackball and dont see how that could possibly get less than 5" square.
as whammoed suggested, i think you should look into a smaller trackball.  i think there was a thread where someone had some penny and giles balls that were really small..

Wow that's a lot of $$$!

For the most part tballs are standardize so most use the same footprint.

What about hacking a trackball mouse.

Someone did it recently and I am going to start mine soon

Just my 2 cents

I hacked a logitech marble mouse for a small cp, and it worked really nicely. I just took the top off the mouse and carved the bottom of the panel so it would fit.

Not as nice as a "real" trackball, but fully functional.

Holy crap, that one is TINY!  If you ever wanted to build a 1/8 scale Centipede, that's the trackball you would use!

Thanks for the replies guys, I may go with that smaller one from Happs since it's got the USB already.  It's not that much more expensive than the Happs 2 1/4 with USB.

I read that those 8mm trackballs are only like $1.50 each.  I submitted a question on minimum order requirments.

I may have to order like 100,000 to get em

hope not

If you can hack a mouse, the Ultimarc is dirt-cheap. I highly recommend buying the Ultimarc and just hacking a mouse. It works just as well, the trackball is small and compact and they feel just like Happs.

Bgnome, Wow! Keep us posted Hoagie_one as to price. I would love own a few of those!

I was able to grab some Penny and Giles USB 2" trackballs off of Ebay for $8.00, they are only 3.25"x3.25".  They are REALLY nice.

The price is right too as long as you don't mind the actual ball itself being smaller too. If you e-mail Randy-T I'm sure he would give you the dimentions.

Umm if you don't mind using a USED or refurbished trackball, you can use the original Missile Command cocktail or Centipede 2 1/4" trackballs. (I'm talking the originals by Atari, made with a metal base rather than plastic). They are basically about 4" x 4" (maybe a bit bigger).

Hoagie_one......ever hear back on the trackball email? Curious about these as well. Thanks.
