Hey there, nice to meet you.
I've tried to build a circuit to perform fade in - hold - fade out loops. Now i have this challenge to insert 3 potentiometers to control time loop lenght, maximum brightness and hold time each pot. Trouble for me is to resolve need for long RC time constant when the 2 other potentiometer are controlling different parameters.
I've created a time-intensity chart to explain what am I talking about.
the loop time goes from 5 seconds to 20 secs, i guess it is enough to create an off time effect long enough to be noticed
I've assumed that the brightness potentiometer also defines number of HB leds in circuit.
thanks
the real proyect involves many colors for sculpture lightning...also controls fountains pumps relays to be sequenced via MIDI with music!!!
