I am interested in building my own basic spirograph that will have three motors (with mirrors attached) and each motors voltage controlled by a potentiometer, a fan to blow air over my laser module, and the laser module itself, all powered by a AC/DC power adapter. This project will not use a microcontroller as I do not know the required programming languages nor enjoy creating my own complex circuitry.
I need help knowing which parts to purchase. I have already bought my 5mW Green Laser module which is powered with 3 volts @ 250mA. For the power supply, I am unsure of the voltage (Either 3 or 5 volts) to choose. It should be regulated so as to keep the laser in good condition. I am leaning towards 5v as I could run a CPU fan over my laser module to cool it as the module will be left on 24/7.
I need suggestions on which motors to purchase to glue mirrors onto, and what potentiometers to control the speed of the fans. If I opt for a 5 volt supply, will I need a resistor to keep the laser from getting overloaded past 3 volts? For potentiometers, what would be the proper Ohmage to raise the power of the fans from 1 volt to 5? There are so many different Ohmage ratings for potentiometers that I don't know what to select for a 1.5v, 3v, or 5v motor.
Any advice, corrections, or help is greatly appreciated.
