My project idea is to hook an optical mouse sensor and an lcd up to it and then attach it to my table saw fence to give me a digital read out of the cut width. The fanciest mice have a resolution of 6000dpi, which translates to 0.04mm which is crazy accurate… So far I have the LCD part of the equation working so all I have to do now is hook up the mouse.
