VCO Idea

[Mitchell Hudson]

    I have been playing with the breadboard and my Forest Mims books
from radio shack and have made the most glorious display of running LEDs
with a 4017 decade counter and a 555 timer. I must point out to all the
beginning DIYers that a small success is most inspiring! try it.

    So anyway I had the idea that I could feed each of ten outputs
through a pot into a an op-amp and I would have a sequencer! Then I
thought if I ran the timer fast enough maybe this could act as a VCO
with a wave form that could be shaped with these ten pots.

    My question to the group is do you think this is possible? it seems
to me that I would want to make my 555 timer voltage controled at ten
octaves to the volt, assuming that it would take 10 clock pulses to send
the 4017 through one complete cycle.


your comments greatly appreciated
Thanks
