im trying to make my own laser show... i have a few motors and i got the potentiometers too... when i hook up the batteries with the motor n the potentiometer nothing happens when i turn the potentiometer... do i have to have special motors that can have their speed adjusted? do i need any other parts? and will a dvd burner motor work?...

im using this kind of potentiometer http://www.radioshack.com/product/i...&cp=2032058.2032230.2032275&parentPage=family ... its about 2 inches tall n the bottom is about a inch across... is it too big?... it says somethin about .250 watt


any ideas for other potentiometers?

thanks for reading....
