    [posted] Custom gem stone Trackball

    Custom Trackball using Teensy++2, ADNS2051 mouse sensor from Apple mouse, amethyst ball approx 2 1/4", and Seimitsu arcade buttons. Using a Teensy++2 because eventually will recreate the PantherXL. Right now working on Trackball portion of what will be mouse and custom joystick

    Next will add the little joystick module for horizontal and vertical scrolling
    Using .125" silicon nitride balls for Trackball suspension...works great, better than factory suspensions of Trackballs I have used

    I modded one of the Seimitsu buttons with a couple 3mm white LEDs I had on hand. I don't like the look, so will wait until I get 3mm purple LEDS. 5mm LEDs will fit in the normal size Seimitsu buttons, but I also have a couple small buttons.

    That looks really cool!

    Was wondering about using an RGB LED for status/progress/modes, etc.

    ADNS-2051 configuration help

    I would have been totally lost without the Arduino IDE software. I do have a question. Here is a page from the ADNS2051 data sheet. How do I send the configuration to the ADNS2051. Specifically, I want to make sure the RES is set to 800 counts per inch, and would like to set Sleep to Always awake. What is the line of code to put in the sketch. Thank you in advance

    I was going to get a blue translucent ball so that it would glow purple with the red sensor light. Then a friend got me the amethyst ball for Christmas for this project, so I decided to add blue to the red sensor light to make purple. It ends up being a neat effect with the gem stone. Some of the red and blue mixes to make purple, and some doesn't depending upon how the light bounces around. It ends up being like a color change ball, because the mix of red purple blue changes with every move.My #1 design criteria was functionality, but it did end up looking really cool. Thanks
