I wonder who will be the first person to bundle it with a usb>dmx adaptor and some kind of artnet client, would give you a very cheap artnet node on a network.
I was going to say you would just need to recompile Open Lighting Architecture, but I see they already support ARM, so it just needs installing really. If you wanted out the box stuff, adding an Enttec Pro Dongle would still put it £30 below Enttec's ODE ArtNet node and do Tx/Rx. Or adding a bare board Open DMX USB gives a Tx only node for only £55. That's all just sticking together out of the box components, so following some step by step instructions. As others have suggested, if you do a bit of hardware work and can implement DMX locally, it should work out a lot cheaper.
So who's going to be first to get the above stack working and post instructions?
As others have said, the graphics looks amazing too, given what its coming from, apparently its got a h264 chip onboard or something.
