2 cascaded resistive dividers with ldrs

[Martin Czech]

The idea with two cascaded resistive dividers with ldrs in the upper
legs (no buffer) is not so stupid...

Do you know how the current/voltage ratio curve looks like?
Invers expo, i.e. log shaped (I say shaped, it is not log something).

So perhaps instead of searching for inverse pots, just put in
two ldrs, voila Q control , if you want voltage controlled.

Possible problems: temperature sensitivity.
I know nothing about that except that there is one.
