How do you get the motors to spin at the same speed? I have everything done, I just. Ant get them to run at the same speed.

I didn't think you would want that much, I'm going to try to make it myself. Thanks again.

Just wanted to clarify, I meant the entire thing.

@drumerkid1014 These are small DC motors that start at about 3V and max at 6V

I have done everything, but just can't get the motors to run at the same speed. How do you make them run at the same speed and opposite directions?

@drumerkid1014 Opposite directions is easy. Reverse the polarity of the wires to one of the motors. Speed is a little tricky. Try putting a small variable resistor in line with one of them...Good luck.

Sorry, this is very important, please answer ASAP. Did you use dual axis diffraction gratings on both of the motors? Or dual on one and linear on the other?

@drumerkid1014 First, I always answer ASAP, so you don't need to keep asking.
And yes, 2 axis gratings on both motors. You can get the gratings at my web site.

@Starcross42
Could I possibly buy this off of you?

@drumerkid1014 I happen to have an extyra one that I made just sitting around. $75. Still interested?
You can order the diffraction grating from my web site using paypal, and any Radio Shack will have the motors. But if you still want me to make it for you then go to my web site and make a paypal payment for diffraction gratings, and when you get the option of $6 just change that to $75. It can be in the mail this week.
