timed fan speed controller?

  1. Does it exist? I'm running a wind tunnel 6 on a speed controller, and it works great, but I'd like to turn it down at night. It's a little noisy.

    I'd need a timed variable speed fan controller. Probably digital. It would need an internal clock so I could sink it with the cool tubes. (overlap of course)
  2. I don't think it would be too hard to make. A few diodes, a rheostat, 2 power supplies, and 2 timers.
  3. I think I see where you're going with that. I'll do some electronics research.
