A couple years ago I built a stand for my trackball mouse to add a scroll-wheel and middle-mouse button. It was functional but the implementation was not practical for everyday use. With my hobbiest electronic engineering skills and a strong desire to find problems that my 3d printer can solve, I built a PCB to hold an arduino-like controller, a nav switch and a couple tactile buttons, as well as a a case that fits underneath the mouse and places the controls in ergonomically sane spots.
If you’d like to recreate this, you’ll need:
- A Trackman Marble – https://www.amazon.com/Logitech-Trackman-Marble-Four-Button-Programmable/dp/B001F42MKG/ref=sr_1_1?ie=UTF8&qid=1516288281&sr=8-1&keywords=trackman+marble
- You’ll need to have this PCB created: https://www.dropbox.com/s/7y1sbcxz0gddipu/mousetrapv2.brd?dl=0
- And you’ll need the following parts:
- A pro micro microcontroller: https://www.sparkfun.com/products/12640
- Screw-in rubber feet: http://www.acehardware.com/product/index.jsp?productId=3678399
- Two right-angle, tactile buttons: https://www.mouser.com/productdetail/612-tl3330af130qg
- A nav switch: https://www.sparkfun.com/products/8184

- Close up of the finished board in-situ

- Track-ball sitting on top of the mousetrap I designed, with my radial cable organizer cleaning things up

- /r/battlestations!
-
- purple PCB from Laen’s https://oshpark.com/ … so cool looking.

- prototype, this revision was a little wobbly (and the wrong color)
