digital timed potentiometer

[banditpowdercoat]

Would it work to use a transistor, With say a R/C circuit on the gate? use a Pot to vary the charge time of the capacitor. And the charge voltage of the cap determines the gate signal of the Transistor? maybe a Mosfet instead of transistor? It's been to long since I fooled with electronics. Mostly 600-4160V now I play with

Edit, I found a site with a WHACKLOAD of different schematics

I'm looking at the Fading red eyes one right now.
