Introduction: Two-dimensional Vectrometer
The Two-dimensional Vectrometer - A mouse alternative
While meandering the internet I found a cool roller mouse from Judy of the woods ( http://www.judyofthewoods.net/diy/ergonomic_mouse.html ). I fancied a go so I made the first of my Two-dimensional vectrometers!
The important bits of an optical mouse are just under the green cover, the red coil of wire slides up and down the copper pipe for vertical and rotates for horizontal movement, a couple of levered micro switches for the buttons. It's sturdy enough to use on the sofa without fear it'll be broken by falling off or being sat on.
