I'm seriously considering building a mech, as that type of combat robotics appeals to me a lot more than watching some 320 lb machine destroy my pride and joy. But I worry about the wireless video solutions we're talking about. Specifically, I worry that any fixed-frequency gear will be rendered useless at just the wrong moment, or that we'll have a collision between two semi-standard NTSC rebroadcasters.
I'm going to buy this used linksys 802.11g camera:
for $60 to see if I can cut it down by taking it out of the case and whatnot. The wired ethernet interface is a waste of space and weight, but this was the cheapest and smallest 802.11g I could find.
I'd imagine that a single 802.11g network could be shared by many of these cameras without danger of interference. And if the venue didn't want to spring for a single shared router, I can do a point-to-point network with my laptop.
I'm just tossing ideas out there. I can use this camera even if I don't manage to put it in a mech. But I wanted to start this thread as a place to discuss the video situation.
