Before my father passed away a few years ago, he was working on a lighthouse project to set in front of our lake house. The project was partially completed, and the family and I would like to finish it in his honor.
I'd like to bring it to life with dusk-activated timer circuit that will turn the 120v incandescent light off and on in a smooth wave-like brightening and dimming with about a 2-second cycle. It looks like the dark-detector circuit (fig. 1) in Tony van Roon's will get me much of the way there, leaving me with two main questions:
1. How do I produce the gradual brightening and dimming of the light?
2. How do I actually control the light with the low-voltage control circuit? Would a triac be most appropriate?
