    I know resistors in series simply add up... but is there any way to
    mulitply resistance?

    eg: can I take a 10k pot and make it work as if it were a 100k pot?

    You could use a 10k pot to drive a servo which would turn the 100k
    pot degree for degree with the 10k pot.

    What do you have in mind?

    Or even using the 10k to control a 100k digital pot? Or even just a

    well im still dwelling over what a 555 timer can do. id like to have 2
    pots... 1 to adjust the duty cycle (without changing the frequency),
    and another to adjust the frequency.

    the pot could bias a MosFet to be used as a v-r.
