    DIY arduino based antenna diversify

    The video switch is a module from China. act like normal camera switch onboard. I took the mircrocontroller of the board, use a arduino NANO to control it. use three receivers and three antenna. monitoring the RSSI. also monitor the power of the battery and build in a alarm. more to come. bench test is ok. when the weather here is good, will post the filed test the source code. the video switching chip is PI5V331. have to way. 4 Click image for larger version.

    Interesting way of doing it. Was the red board intended to switch cameras on the plane? Or was it intended to switch between stationary cameras?

    How does it work? Does it detect RSSI? or does it measure video quality like the oracle?

    base on RSSI.

    I would say that bnn's is better than that, because:

    1) His has a screen
    2) easily customizable
    3) If it is stripped down to a bar MCU rather than an arduino board it would be cheaper
    4) His has diversity x3 as opposed to the rangevideo's diversity x2

    use servo library to put out 1000us for channel 1, 1500 for channel 2, 2000 for channel 3. really simple.

    you might want one button and one toggle switch(on/off). toggle on = auto switch rssi. toggle off = manual mode. press button to cycle among video channels.

    obviously you connect the receiver outs to where the cameras would be connected, and the VTX port is the signal that goes to your goggles. "spare channel" = connect to PWM pin on arduino. rssi to analog ports. remember to use a common ground or the PWM port will act funny

    actually I take the on board MCU of. I use my own logic to control the switching chip. all the analog input with pull down resistor, I want to use manual, I just power one receiver on, it will just choose the one that on. thank you for your advise.

    the chip can handle up to 4 channel, and have two switching channel, that mean you can choose up to 8 channel. Yes, because I build it, I can make like build to suit. I can do every I want, like build in lipo tester. any feature that the arduino can handle.
