Hi, Im new to the forum and I was hoping someone here could help me out. I have just discovered the world of laser lights and I have become obsessed. I am trying to build one of my own and I have an idea of how its going to go together my only problem is I guess I need a low volt and VERY low RPM motor or a variable speed motor to spin my piece of textured glass that my laser will shoot thru. This motor also has to be fairly small 1 - 2 inches long. I have an extra pot from a guitar I fixed so I think I'll try to use that as a speed knob (if possible). Also I think a 9v battery will need to be used to power it since I want to wire an on/ off button in it as well. I was looking at the Solarbotics Gm2 motor and I was hoping something like this would work, http://www.robotshop.com/solarbotics...-2-offset.html I just dont think it's a variable speed motor and 38 RPM is still really high for this application. If anyone knows of something like it or something better for my project please let me know. Also if you have any questions for me please ask. Thanks very much!
