To further dress them up, I milled out some plastic finger guides to go around the buttons to provide some tactile feedback regarding where the buttons are and guide the finger to the center of the buttons. They make a nice finish on the capacitive touch buttons. In the last week, I also located some nifty nickle silver buttons that allow me to solder wires to. Currently, the prototype is making heavy use of double stick carpet tape to hold the parts together in place of where Velcro will eventually be. The ball socket and scroll wheel are kinda big and will need support from below to be stable. I'm also coming to the conclusion that I'll need a Velcro covered base plate that is about the size and shape of a mouse pad to mount all this onto. The Velcro will provide an attachment method for the various peripherials such as buttons, scroll wheel and the ball socket itself. Currently, I have some stretchy Velcro (Velstretch it is called) on order that has promise to allow it to be attached to the hand support that can be molded into any shape. I have been working toward the goal of eliminating the outboard breadboard by migrating the components (processor, LED and scroll wheel) to the trackball area to create a self contained unit that only requires the USB cable. Even though it isn't complete, it is much more desireable to use verses the 20-year-old Logitech trackman I was using. The old sand and water prototype was slowly growing mold and needed to be replaced ASAP, especially since the prototype unit is my every day use trackball now. The new sand and clay mixture is just right. I even tried using metal wire mesh, but none of those approaches yield an acceptable end product. It took me quite a few tries to get to this point with several failed attempts along they way including a cast silicone mat with copper wire running through it and even mini beach balls filled with air. I filled a regular balloon with the material and it is meeting the right requisites of being firm but moldable. In the last few weeks, I have tried an alternative hand support material made from sand and clay that I'm prototyping. It has been a while since my last update. A nice, neat and elegant solution to scrolling that has no moving parts and is ultra compact. Now that I can control the polling rate, I can control the scroll speed up and down the page which is awesome. In place of where it would be, I simply designed a new middle mouse button that has smaller half-sized touch pads above and below the middle mouse button that allow for scrolling.

The scroll wheel with it's opto-interrupters was working perfectly, however it was a bit on the large and bulky size. In addition to these changes, I have stopped development on the scroll wheel.

I was able to ressurect fallen players while in combat with my pinky! I was able to map this to the F4 key and it works perfectly. As a test, I put a new fourth button on the trackball for my pinky finger to use and played WoW for three hours. I took extra care to be sure that I can send multiple keyboard keys pressed at the same time too, so now up to six buttons can be sent at the same time. That being the case, I can now send both normal mouse clicks and keyboard strokes. Teensyduino allows the Teensy board to interface as a keyboard+mouse composite device to the computer. Now, when I say whatever I want that button to do, I also made vast improvements here as well. These changes have added ease of use and increased overall performance to put CPU resources to use where it is most needed and stopped wasting CPU cycles on less important things. In addition, I added a key-to-pin mapping array that allows the pins to be remapped easily to whatever you want that particular button tied to a pin to be doing. This greatly helps manage CPU resources to ensure that each button gets the attention it needs without hogging up resources to do it. Each button's polling rate can now be specified in milliseconds. Instead of counting CPU cycles, it is now based upon timetamps.

In the past few days, I have almost completely re-coded the majority of the capacitive touch buttons detection code.
