Well, I'm trying to use a series of incandescent bulbs to display information. First job, obviously is build the physical display. it's going to be rather large, so I'll skip that part here, but really what is important and the help that I need is... How can I control each light individually, without having the power going through my system? I'm going to have a lot of lights to control, so making a circuit out of the entire display is possible, but at this point, I am really looking for the beginning of the plans. Would this involve a solid-state relay circuit? Would it require one ssrc for every lamp? What sort of interface with my system would control the on/off of each lamp? How expensive is this? Long-term goals are to treat the whole display as if it were an external lcd/vfd, displaying marquee-like information, and/or creating a lightshow. I kind of realize the coding involved, but I really don't know where to start. I'm looking at about 2,000watts going through the whole thing at once, so I'm not ready to take a big risk with my mobo. I do have a bit of experience. I used to have a VFD display that I modified existing coding to work the way I wanted it to, but that was like 4 years ago, I think. I'm almost at square one, but my willingness to learn and motivation to get working on this project is tops. I haven't posted anything here in years, but I'm starting this large art project, so I'm really trying to get ground-roots information right now. I'm looking at the possibility of several hundred low-wattage bulbs, so if this requires massive amounts of circuitry and big bucks, I don't know how quickly I would be able to do this. Any help you can give would be greatly, greatly appreciated. Thanks a bunch!
