Hi all,
I've now set up permanently installed systems in all but 2 classrooms as they have Promethean IWB's. To support staff and students (who now calibrate these for the teachers because they love doing it) I made a checklist in case they ran into trouble. It's quite explicit but the teachers who have had to use it said it helped them and the children get their board up and running. They only needed it for the first few times untill they got the hang of it.
Ben asked that I post it so I hope it helps. All wiimotes are mounted to the data projector which is ceiling mounted. They are remotely turned on to sync by a fishing line which hangs down the wall next to my desk. The fishing line runs up the wall, through a hook, across to the data projector through another hook, down the pole and is then looped around the wiimote through a hook which covers buttons 1 and 2. When you pull the line, the buttons are pressed and the wiimote syncs. The wiimote is mounted upside down. The fishing line is almost invisible, cost virtually nothing to set up and works flawlessly. No more racing back and forth across the room between wiimote and laptop before the syncing process times out. Too easy!
