Hi all,


This past winter I built a new machine for doing more professional aerial photography. I got a 3 axis gimbal for my Sony NEX 5. I decided that to take full advantage of the gimbal, a second operator would be beneficial. My main RC transmitter, a DX7S, lacks the channels, and programmability to control all of the gimbal functions the way I wanted.


Instead of buying another cheap transmitter for gimbal duty, I decided to make one. This would give me the ultimate in flexability.


Reasoning behind the project:

1. My DX7 is out of channels to support flying, gimbal and camera shutter duty.

2. I want a second person to have their own transmitter. I want to fly, and I want them to operate the gimbal and camera. I have the NEX5 HDMI to analog converter, so I can switch between sony view and a frame mounted camera for FPV. I plan on adding a second FPV system so we can both watch our feeds seperately.

3. The IR shutter control I am using for the sony requires that video stop / start be tied to a momentary switch. Building my own controller and doing the code myself, I can make sure this is implimented properly and fires the shutter properly.

4. I want to be able to hand my gimbal controller to anyone and explain how it works in 30 seconds. To the complete noob, handing them a fancy RC transmitter with switches and knobs all over it can be intimidating. I can make my own stream lined controller that is very simple.

5. I want an all in 1 solution. I planned to include 915 mhz telemetry with bluetooth bridge to my smart phone in the case. I also wanted to have my phone mount to it. I hate carrying around all these seperate little gadgets.


Here is my first pass at it. I still have work to do on the code to get it working. An arduino Uno formats the PPM signals to the Spektrum module. All is powered from a 2S lipo.


Not the prettiest inside, but it works. I used a multirotor power distribution board incase I add functions later and need to supply them power. It also had 12V and 5V regulators built in, which come in handy.

This is excellent!

I like your power distribution :)

Nice work,nothing wrong with that.A bit of vero-board might help rid you of some wires.I noticed you have some neat metal inserts for the screws.What are they called again?Trouble with inserting them?

I have been using these inserts on my of my projects. Press in. Works well.

Can you post the ardu code please? I'm trying to make something similar.

Hi, what is the name of your PDB? Thanks!
