    Im trying to control a pwm solenoid... all i need is a constant 97% DC @ 100Hz. dosent need to be variable or anything..

    could this be accomplished with just a simple 555timer output to a NPN transistor to regulate the ground?

    PWM control of a Solenoid seems a bit of an Oxymoron?
    Any more details?
    Must be a vibrator of some kind.
