![]() i think this is in the right forum.
is there someone here that is or knows about i think software technician. i am looking for somebody that could tell me or do it for a price,a digital timed amperage drive potentiometer. ![]() the reason for this is i am placing it on my LED array to produce dawn dusk for my reef.i will supply you with all information needed. tried looking for such thing as plug and play NO luck. |

![]() Over how long a duration do you want the pot to move? ie from off to full on.

![]() i want within 1 hour morning and the samefor the evening.
the blue LED wil lcome on 1st at 350ma for half hour then goes up to 700ma with whites at 350ma then by the time the hour is up the blue will be at 700ma and whites 1000ma. vise versa for the evening. or maybe better have it running on real times setting. |

![]() you could likely do it mechanically with the hour hand of a clock that move the pots very slowly from off to on and then in reverse, it would be a fun DIY.

i want it to be as compact as possible |

![]() 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 http://ourworld.compuserve.com/homep...epage.htm#menu I'm looking at the Fading red eyes one right now. Ohhhh, check out the Automobile Interior Lights Fader
