Well, last year a friend and I did a show using DMX. We use Mac's, and like the native integration, so spent most of the year writing native Cocoa software to control our show (and visualize it, etc). Along the way, we decided it would be fun to develop our own controllers, and pixel controllers. We knew a lot are going to E1.31, but for us, it felt like overkill. We wanted more channels, but as we plan on using pixel control to accent the show, we don't feel we need tens of thousands of channels. We felt if we could drive 3K or more channels from a single "dongle", we could live with that (we had two dongles threaded last year, and felt if worse, we could do that again). We also like the ability to refresh at 25msec, so that was another one of our requirements. Anyway, we thought about intelligent ways to do our protocol, but decided to just go with a "stupid" streaming approach (and thus named it Stupid Streaming Data, SSD). It actually sends two streams of data down four wires. Anyway, we have the dongle completed and running, and have a DC controller bread boarded. THe mac Software is updated to support it. Anyway, didn't know if anyone was interested in expanding to a larger amount of channels, but not have to worry about the ethernet setup for E1.31. We are over at www.diyblinky.com. We move slowly, as this is a huge learning curve for us, but this is purely a hobby for us. So to us, it has the right priority.
