Josh,
I'm currently working on building that exact handheld monitor setup but with a SmallHD 701 monitor. I would love more info or even photos of the details of that great power solution you made. Its a Sony plate that passes through to the monitor right? I would appreciate any details you have. I would even be interested in getting something similar from you if you are making more or other versions. Thanks for the info.
