RF Tally System
Posted 28 August 2012 - 04:31 AM
I intend to test it out fully this weekend but thought I'd share the results and a few pics once I've put it through it's paces but all initial tests seem to be positive.
If I remember rightly there was a fellow op on here that was building something similar a few years back but he seems to have dissappeared along with his system so I thought I'd give it a go myself. I know there are some relatively low cost options out there and this cost a little more to build but I really wasn't keen on having to run a cable down the outside of my rig if I could avoid it.

Is it posible to run power via d tap or another 9 volt battery system???
The receiver is native 12-18volts. I powered it from the 12volt output on my sled just because I had a spare cable laying around. I think if I made these up as a kit I would probably just throw a 4 pin xlr socket on it so you can use anything that you want to feed the 12volts into it. I could make it with a lemo socket but that wouldincrease the cost considerably.

At this stage it is a 9 volt battery for the photocell relay but the transmitter is running on a A23 12volt battey internally as I built a lot of it from off the shelf parts to an extent but I am looking to integrate the power for the transmitter and the photocell together which will be 12volt. This version is really just a proof of concept and so far I am happy. I tested the transmitter to about 150' so that was a small bonus as it could be setup in a studio etc. when you have no return telemetry on the camera by connecting to the vision desk telemetry directly.
how about transmitter only 9v option ???

sensitivity of the photocell wasn't quite right but I adjusted that at the start of the day during camera checks and was fine for the rest of the day.
