That was pretty cool the way those operate! He must be using a micro controller for light control if he can program stuff like that into his signals. I'm not in a hurry for any signals, but I probably will get in touch with him when I'm ready, those really are neat and quite versatile too. I might inquire about the website, I would like to see what all he has. The lights are very nice too. Thanks for the demo video showing their operation.
The thing I was fiddling with here is much less sophisticated, just some IC chips, caps, resistors and LEDs. It will never be able to do what you have demonstrated here. It's basically just a 'fiddling' project for learning, and I enjoy fiddling with these things. Not sure it will ever actually get used, but I might learn a few things.
