simple LFO circuits…

i was reading over this thread on diystompboxes.com about building an analog LFO circuit for some wild noise idea i’ve got brewing in the back of my head. i started messing around with some of the schematics on there and got a drifting saw wave out of it after a while. i was trying to take a picture of the wave itself on the oscilloscope which obviously didn’t turn out all that well. so many breadboards. yeesh.
