Will, let me know about that rebuilding and the mods. If I'll like your design I will buy one from you ;-)

 

Michael, of course you will have a stable image on the screen. It's digital! The problem is more, if the signal is too weak (or disturbed) you instantly get a black screen. The thing with digital signal strength is that you can not judge it on a screen, you need to measure it. Accordingly you may see that the signal strength could drop rapidly if you move the transmitter.

 

Good luck.

Please keep us all informed with your progress! This would be huge for me, I'm just starting out and right now can't really even spring for the Camwave, but I've been doing alot with dslrs so I really need a transmitter and have had discussions (arguments) with production every job i've had about how they need to rent one. If you made a more production ready prototype under 2k I would be interested in buying one from you as well.

In case anyone was wondering, here's my progress:

 

I'm currently moving this week into a new apartment, so I've had to halt work on it for a few days. However, last Tuesday, I had some other Steadicam ops over to my place to show off my work so far.

 

  • I have a power cable built to convert 12v to 5v but still sustain the 3amp draw on the device. Runs off my PRO2 Aux power.
  • As a test, I set up my iPad 2 to transmit The Dark Knight from the transmitter (powered off my sled) to my TV in the living room. Everyone saw me transmit upwards of 40 feet at 1080p through a few human heads and a glass window. That was just using the device as it ships (with the stock PCB antenna).
  • I've begun soldering down pigtails to the PCB to augment and raise up the transmit dBi (4-5 dBi per antenna, 4 antenna total). When I'm done, it'll have 4 external antenna.
  • I plan to do a test at Clairmont Camera sometime next week to test my antennas, and see what my output looks like.
  • Depending on the transmit power and capability, I am also going to start testing power amplifiers to augment the RF output power at the transmitter. I need to read up on FCC limitations on the 4.9-5.9Ghz band.
