I've been successfully using the Asus WiCast device powered up with my Tekkeon battery packs for a DIY Wireless HD Video stream from my DSLR to a remote LCD monitor (as seen in video here). Those Asus units have been discontinued for quite some time. These rebranded 5GHZ Wireless Streaming HDMI devices have been around, but has now been upgraded with a smaller transmitter. One downfall is that the transmitter has a built in male HDMI connector which needs to be stepped down to a mini HDMI if it's to be used on a DSLR camera. It still requires a 5V power source for both the transmitter and receiver. I remember someone using this brand at some point, any comments on this new version?
