  • Good morning Mr. Pinter!

     

    I was idly spinning around in my chair last night looking at my many remote controlled gizmos and gobs, when I was suddenly struck by an idea for a new project to work on: a custom "universal" 2.4 GHz transceiver.  I want to be able to switch control from my quad-copter to my RC car and back using presets (I'm planning on using an arduino for this), but I don't know how to approach tuning signals for the transceiver.

     

    Is there a way to "record" PPM signals from a 2.4 GHz controller so I can disguise my custom controller as the original?  I've seen it done for infrared signals, such as custom arduino universal remotes, but I haven't found any that work on 2.4 GHz channels.  The idea is to be able to program presets into my controller by having it record signals from the original controller.  Do you know of any software that can do this?  My problem is that I don't know what channels my RC devices work on.

     

    Sincerely,

    José Justiniano

    Hello Jose,

     

    Yes you can do It.  I have done it before myself.  Ofcourse you will need a Vector Signal Analyzer (VSA). You can pick you up for $150,000.  Sorry not available at Radio Shack.

     

    I would suggest building a programable controller that you can enter seneral RC codes into manually.  Then you can switch from one toy to the next.

     

    Hope this helps,

    Hello again Mr. Pinter!

     

    Thank you for your quick response!  Yeah, the Vector may be a little out of my price range.  However, I've seen slightly more invasive ways to hack a radio receiver so the arduino can read PPM streams:

     

    RCArduino: How To Read RC Receiver PPM Stream

    In this case, arduino is integrated into the rc device itself for added functionality.  My goal is a little different: I want to integrate arduino into the controller, I could possibly program some complex maneuvers into the arduino to execute on command (quad-copter backflip for example).

     

    Do you think something like this could be done with a transceiver?  Granted, it's not as magical as a 2.4GHz universal remote, but is there a way to gut existing controllers to find out their channels and PPM streams?  Or would I need to surgically remove the IC along with the transmitter and hook my arduino to the IC?  I'll have to stick with IR for the universal controller, but maybe I can still switch to known 2.4 devices.


    Thanks for your insight!

    I do not know if it will work. I would not consider this approach or this project.  I do not see any commercial use.  But if you want to learn something.   Give it a try and find out.

     

    Hope this helps,

    Thanks again Mr Pinter,

     

    One last question: what specifically do I need to find out with the spectrum analyzer?  The Vector is definitely well suited for analyzing the bajeezus out of all signals in the room and beyond, but I'll be holding the remote mere centimeters from the antenna.  Could I achieve what I need to with an airView spectrum analyzer?

    A Spectrum Analyzer only displays the signal.  It will not capture and retransmit It.  Radio development is not for the fault of heart.  from what I understand you want to capture an RC signal,  save it and rebroadcast the information.   This is npt going to be successfully endevour. 

     

    What you need to do is program a device with the information you want to transmit.
