    Hello guys , I finally started to mess around with electronics ( mostly making small robots and stuff like that ) I'm working at the moment at a lightsaber replica , I made the L.E.D strip , with some diffuser , used a 9v battery to power them but I want to kick it up a notch , and try to go for the humming effect . I've found a design that uses a small dc motor to imitate that sound . Would the small dc motor do any good , or a vibrating motor ?
    I don't think I'm skilled enough to work with a soundboard yet , any tips ? :D

    DC motor with a fan controlled via PWM should be able to replicate humming effect.

    Try an audio oscillator controlled with an accelerometer.
