[sdiy] pseudo random LFO

[Mitchell Hudson]

    So after that discussion of pseudo random voltages a while back I
got the idea to make one of my own. I liked the idea of mixing several
LFO's together. So am I starting with a simple LFO from Tom G's site
(thanks Tom for providing a most excellent web site). I changed it
slightly by taking out the switch between the triangle and square
outputs and using them both. It looks like I can do this? I also want to
use this with a 15v power supply. Which I am not so sure about. Could
any one give me a tip, can this circuit with 15v or do I need to chang
something?
     The last thing I want to do is mix all of the outputs into one, I
haven't drawn this into the diagram yet. I am thinking to use the mixer
from the Forest Mimms book on op amps.

Thanks
