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!

you want to motor with a super low rpm you are looking for something around 1 rpm.
i used an mini rc servo motor and then added a few more gears. small and works great.
That will be the cheapest way to do it.
what you are doing is making an effect called the lumina wheel.

but it sounds for the most part like im doin it right? luckily a friend of mine wants to help and together we were able to figure out how to wire up the 9v battery to the on off led button then to the pot then to the motor (all radio shack had was a 5800 RPM motor so i got it just to experiment with and the pot worked) now we just have to figure out how to get the laser routed in so when i turn the thing on the whole device turns on at once. the thing we are having the most trouble with now i guess is taking lasers apart so we can skip the resistors. pretty much we have no idea what we are doing and so far its worked but its been difficult and info would help alot
