You're looking for an astable circuit with 4093 ??
An externally hosted image should be here but it was not working when we last tested it.
On the other hand, the three component circuit in post #6 can be knocked out on a breadboard in a few seconds and find out.
Find the "CMOS Cookbook" somewhere. It might even be scanned at this point. Yes the book is from long ago, but CMOS basics are basics, and it covers oscillators.
Having said that, I don't know that the relaxation oscillator is the best choice for something slow like an LFO.

Totally agree with you. I just posted an example in post # 6.The circuit in post 6 is a relaxation oscillator.
The classic astable multivibrator uses two normal gates or two transistors.
Now, circuit with two logic gates:
The 0.59 comes from circuit theory, as does the RC. Every RC based oscillator will have a period calculated from the RC product, but the associated number depends on the circuit details which is why your original question could not be answered until you told us which circuit you want to use.
