I’ve been trying to use my iPad in the classroom as much as possible, as a device for use in schools it is close to being perfect. One of the drawbacks has been working out how to get what’s on the iPad to be projected onto my classroom wall. You can connect it with the iPad VGA connector to a computer and project that way, but only a handful of apps support this. This can apparently be expanded somewhat by jail-breaking , but I don’t really want to go there.
Then last week Wes Frier alerted me to an App called Air Sketch. Air Sketch is a fairly simple drawing application with a killer feature, it will broadcast whatever is on the screen across your network to a webpage. If you open that webpage in a HTML 5 browser from any machine attached to the same network you will see the iPad screen. Any updates made on the iPad appear almost instantly on your PC or Mac. Air Sketch was £1.79 but there is also a free option to try.
