Hi all
I've been searching through the forums for AC dimming solutions, but haven't really found what I'm looking for. This thread pretty much summarizes what's out there at the moment:

I bought the Velleman K8064 kit, and it works reasonably well but does stuff I don't want it to do. It has a soft start feature which I don't want, and there is a lot of hysteresis on the "on" voltage. The circuit doesn't turn on until I hit about 1.2V, even though I've adjusted the zero-threshold pot as low as it will go. This means I'm losing lots of my 0-5V bandwidth.
Can anyone offer a suggestion for a configuration that will use the full 0-5V range, include opto-isolation, and allow good control over 120VAC, 60Hz?
Thanks for the help,
Nigel
