Ruder-
Thanks for logging in on this. I have solved the problem.
The iOS devices are connected by wifi - wifi from the projector device - the problem was that the firmware on the device was outdated. Don't you love it when you open a brand new box and the firmware is already two version old and there was no particular warning to check it and update it (in this case a process that was very arcane and took forever).
Now that it's running, it's very cool, however - a 2.5x2.5" cube that projects an 8' image from 6' on a battery that lasts for 2 hours (long enough to bore all of my friends).
Anyhow...thanks for the effort - sorry I took this long to reply as the email somehow went to junk first.
Cheers,
Tom
