thoffen Posted September 17, 2006 Report Share Posted September 17, 2006 Hello. I'm new here. I'm wanting to start a simple project to mount a laser pointer to the ceiling on some sort of high precision rotor-type thing to move it around to all directions about the room (I will program the paths, of course). This is because my cat LOVES to chase the laser pointer, and I want to be able to get it to move autonomously (e.g. when I am away from home).Anyway...my question is: what part am I looking for to mount the laser pointer to? I'm thinking something that allows me to move a ball around. It would have to be relatively fast movement with fairly high precision, I think.Thanks for any available input!

ante Posted September 17, 2006 Report Share Posted September 17, 2006 Hi thoffen,Welcome to our forum.You could fit a prism to the shaft of a stepper motor and aim the laser at it. This stepper could then be fixated to another steppers shaft and you got X, Y and Z.Poor cat! ;D Quote Link to comment Share on other sites More sharing options...
thoffen Posted September 17, 2006 Author Report Share Posted September 17, 2006 Interesting...any idea where I might buy a suitable prism? I'm trying to visualize how it will work in my head. I don't know much about using prisms. :) Quote Link to comment Share on other sites More sharing options...
ante Posted September 18, 2006 Report Share Posted September 18, 2006 I don’t know where you live but this came up (and many more) on “prism+laser” in Google!:http://www.escoproducts.com/html/prisms.html Quote Link to comment Share on other sites More sharing options...
