    I have struggled for years trying to understand electronics enough so that I can design circuits.

    I actually have a long history assembling electronics including a few years stuffing pcb's and assembling power supplies for a computer company, but I have never been able to put the dots together to design or understand how the circuits really work.

    All this brings me to my current situation. I have been trying to figure out a circuit that will automatically vary voltage between 5v and 10v. Not just bounce back and forth between the two voltages, but have something like a sin curve variance between the two, if you know what I mean.

    About as close as I have been able to come is an LED flasher circuit, but that creates a hard on and off.

    Any guidance or direction would be greatly appreciated.

    If you tell what the purpose is of this varying voltage and how much current you need, as well as the frequency of the variation, and what is driving the variation, we can give better suggestions.
