Yesterday I successfully tested using a 5.8GHz wireless HDMI sender with the Prop2
Happy to say got good results out to at least 15m line of sight, and ~8m through a concrete wall
These transmit using 5.8 GHz band. Jaycar have a special on these at the moment. There are various versions but I like these because of the compact transmitting dongle (rather than a desk mounted box)
I added a dual output Lipo chargepack for portable testing. There is something cool about having your whole setup battery powered, but viewing the output from Rogloh's DVI driver on a big TV across the room
I can't get Chip's hdmi spiral demo to work right just yet (it comes up distorted), but will dig deeper. It does work when directly driving the same TV used with this testing.
