YXiPad

Wanted to make a clone of AxiDraw (http://shop.evilmadscientist.com/productsmenu/846#), and found this http://www.thingiverse.com/thing:1517211 and used as inspiration.

It is not supposed be used as a drawing robot, but as an XY touch pen, working on an iPad and controlled with image recognition and logic through Rpi with RPi-camera.

It could probably be sexier by using Linear bearings (LM10UU), but I wanted to use the stuff I had laying around.

PS: Ongoing project, and I am heading for vacation now, no updates for some weeks.
PS2: Some pictures might not match last design files, as I am going through several design iterations.
