    First of all I think this is a great project, thanks!
    In the next video could you please cover how to use a 12vdc supply and also where to find the RSSI on other receivers such as the common Immersion or RMRC ground station units?

    • @1cipi
      @1cipi 10 лет назад

      to pover it just use a regular ubec 5v/1a or even a 7805....

    Bruce,
    You are not only supporting the sport, you are also encouraging everyone to learn, play and evolve. I love your simple and no-bullshit design approach.
    Just one "complaint" (not really a complaint, just a request for the future):
    Could you try to put links to the stores where you get your different gizmos and gadgets? Saves a lot of search time, especially when you find some gold on i.e. ebay

    even with hysteresis, it will have those flicker, try RC dampening on those gate inputs instead, it will smoothen the switch transition, the switching is to sharp, we call it noiseless toggle switch in in audio circuits which eliminates pop in audio mixers when a DJ using switched scratching rapidly, anyway the video signal is also analog signals. great video Bruce.

  • @RobB_VK6ES
    @RobB_VK6ES 10 лет назад +1

    Liking the wing it attitude Bruce. Apart from the hysterisis issue I can foresee it may require a voltage divider to to exactly match the RSSI voltages to account for tolerances and possibly even different models or brands of receiver.
    For those with misgivings about the dead bug construction method, while it may look chaotic and a pain to construct there are actually advantages from a signal integrity point of view over using say strip board and this unit is ground station based so issues with viration etc are minimal. I am sure after making the first it will become clear where it would be possible to improve the layout and wiring. Things like cutting small squares of pc board to form insulated islands on the back plain board or to cut similar islands into the back plain copper. Like Bruce said don't get too hung up on the construction even if you need to make a few up to get wher you are happy with the finished article it's still going to com in under $20.

    Typical.. I just got my Skyzone goggles for head tracking with the diversity receiver but then it accured to me, I cannot use a directional antenna on my goggles and also turn my head for the head tracking without loosing signal..
    Back to using a ground station and give your diversity controller a bash.. :o)
    Many thanks Bruce...

  • @gilcd85
    @gilcd85 10 лет назад +3

    Bruce, if my understanding is correct, you may have switched vid1 and vid2 on the CD4066. If RSSI1 goes into pin3 of the LM324 and goes high to pin5 of the CD4066 then vid1 should go into pin4 of the CD4066 and not pin8..
    Don't think this would cause the flickering but still.

    This got to be most complicated use of a copper circuit board. It has only one connection - GND. It is a surprising use, and I had never thought about that method. However I would suggest a perfboard (perforated prototype board). It costs only a few euros and can make nice solid implementation that can last for years.

    • @JLWoelf

      Pro of using the entire copper base as ground: It's a nice shield.

  • @bencornett7821
    @bencornett7821 8 лет назад

    I looked everywhere and was surprised I could not find and answer. I had the controller picking the weaker signal. I fixed the problem by switching the two wires on Pin 5 (control B) and Pin 6 (Control C) on the 4066.
    So Pin 7 on LM324 now goes to pin 5 of the 4066. And Pin 6 on LM324 now goes to Pin 6 on LM324. Hope It saves someone some headaches.

    I see you just feed 5 V into it. VCC and ground . I get that much , but I ALSO SEE A 470 uf IN THERE ?
    From the pin video out on the RX5808 .
    Am i right in assuming I put the 470uF in between the pin VID out and the actual signal out ?

    Hi Bruce
    your work for the hobby is PRICELESS, THANK YOU!!!
    I wander (and I am sure it possible) to make a schematics for 3, 4 and even more receivers connected, to avoid antenna tracking just having multiple directional antennas. can you take few minutes to link schematics for multiple receivers?
    Regards
    Nick

    • @Tryin2FlyII
      @Tryin2FlyII 9 лет назад +1

      Hi Nick if I understand you correctly it is pretty easy to add two more receivers to this circuit ,I was thinking the same thing lol I was looking at the data sheets for both chips and since this only uses 1/2 of each chip there is room for the same circuit on the other 1/2 giving you 4 receivers total all feeding one monitor but don't take my word on it as I'm self taught & not 100% sure how good it would be-I did build this one and it seems to work pretty good I have yet to fly and test it in the real world (I plan on adding the other 2 Rx to see how that works)

  • @WinstonSmith1984
    @WinstonSmith1984 10 лет назад

    Thanks. I hope you add the audio diversity too which can be done on the same chip I think.

    • @andrewgoldberg6301
      @andrewgoldberg6301 10 лет назад

      I added to the basic design so audio switches at the same time as the video. All you need to do is bridge pins 5 to 13 and 6 to12 so that each pair closes at the same time. Then bridge pins 2 to 10 with a connection for audio "out". Then run the wires for audio "in" to pins 1 and 10. Make sure to match audio/video input wires (pins 1 and 4 RX (A) // 8 and 11 RX (B)). I can make a video of this if anyone needs it.

    • @andrewgoldberg6301

  • @power-max
    @power-max 10 лет назад

    Are the video inputs supposed to be the 5.8GHz signals directly from the antenna'so? If so I am surprised that that would work well, but I suspect that you have the video out of separate receivers going into those.
    I would have designed this using small shielded Reed relay switches with antennas connecter to one end, and the other side of the relays joining together at the input of one receiver. That way you are effectively swapping antennas rather than receivers. Aluminum sheiding should stop radiation losses and interference, but let low freq. magnetic Flux penatrate to close/open the switch.

    Go for the LM339 instead of the LM324, check the app notes for the hysteresis, just 2 more resistors. Also the chip is REALLY cheap and fairly common.

    • @qumefox
      @qumefox 7 лет назад

      The LM339 will do the job better, but isn't a drop in replacement. Bruce's circuit would have to be altered somewhat by swapping it.

    Great video Bruce. Thanks. I wonder, is there such a thing as triversity? At the place I usually fly (our club field), I usually fly right to left. We have close to a mile of space each way, and maybe only 100 yards in front of us, so it would be nice to put two high gain antennas pointing left and right and a simple CP for the center.

  • @ROBOFORCERX2000
    @ROBOFORCERX2000 10 лет назад

    Nice one Bruce, I'll give it a go for sure! Here's a question- if it has 2 Vrx's for diversity, would I get away running 2 Vtx's on an aircraft? Lets say if I put one Vtx on my quad with RH clover facing up, and the other LH clover horizontally, or both in a "V" and get 2 matching Vrx's (with the right polarization antennas of course) with each Vtx? Should work?
    Edit: I just realize that I would have to run 2 cams as well...

  • @worthingsteve
    @worthingsteve 10 лет назад

    Hi Bruce, thanks for taking the time to do this... I would like to see if it is possible to make one that works the other way around?
    I think my airwave vtx runs an inversely proportional rssi, so good signal results in low voltage, so for me wiring the system in this way would result in the unit constantly picking the worst signal.
    Any pointers really appreciated. Thanks steve

    • @xjet
      @xjet 10 лет назад +1

      Just swap the RSSI (red) wires over and it'll work with reverse RSSI. So put receiver 1's RSSI wire onto the resistor that currently has receiver 2's and v/v - then it'll work just fine.

    correct me if im wrong, but the Lm 324 is a quad comparator and it seems your using only half, so you could instead use an lm393 which is a dual comparator. (i have lots of lm393's lying around as a result of making lots of line following robots XD)

      @TobyBurt 10 лет назад

      The idea was to make one as cheaply as possible from parts that anyone can get. He has been working on a much better diversity controller but mentions that cost and parts availability are not so straightforward. This is for people to play with, if you are going to be risking mass amounts of $$$$ then you would be better served spending some real cash on diversity as well.

    • @FlyingZayin
      @FlyingZayin 10 лет назад

      Anthony Burt I have good GS for long range missions but I suddenly realized I have two 5.8 receivers in my drawer... Naturally, I'd like to make them work together. Someone mentioned in comments to Bruce's recent post that the controller may remain equally simple but made of better components. That's what I would love to make. Keeping it simple (as my electronics knowledge is below zero) but not necessarily hitting the very bottom of the market.

  • @DF-qe9nr

    how does this hold up when there are storng interferences? would it interpret them as a stronger signal and switch to the worse video ? or does it read the video frames and know which is the best quality video?

    Will this be able to run say two sets of goggles and a recorder?

    Bruce mate I built it but it doesn't work :-(. I bought all the components you said and followed exactly what you did. When I powered it all up the LEDs don't light up and there's no video.

    I don't know why but something annoys me about using a copper-clad board.
    I would have used a protoboard or stripboard.
    You can make it smaller and cleaner looking.

    you mean that you'll make something like a delay for the flickering?

      Sort of. Hysteresis means that once it switches, the other RSSI has to be a certain amount higher than the first to switch back.
