    I suspect that is something that might have shown up with a simple ohm-meter test.

    Makes you wonder whether we really are not back in the early days of aviation or motoring, where we all need to know how to use oscilloscopes, voltmeters, ammeters, ohmmeters, etc. If we are indeed back there, this era shouldn't last too long (I hope).

    It never does, except when it does. But we are definitely in the age of the aviator...those with the broadest array of knowledge, experience, tools, and money usually come out on top. Except when something goes wrong...which it almost never does, right? :eek:

    Today this little beauty bailed me out!

    My #$%^& Zeiss Cinemizer goggles have the most delicate A/V cable, and I've been through 3 or 4 of them. I didn't have any more, so after I buzzed out the cable to figure out the pinouts (argh), I cannibalized the connector and another RCA cable and jerry-rigged a new one, and I was back in the air.

    Nice.
    I've been meaning to use some more robust connectors for the Cinemizers -- I was pondering whether in-line BNC connectors might be viable?

    IMO the problem is with the choice of that 1/8" connector they use as an A/V in and its unconventional configuration. I'm going to have my buddy's electronics tech (they have a guitar shop) rig me up something with some heavy-dudy connector or something. The one I made is probably going to last a day. Maybe two. :confused:

    Here's another useful gadget: a small 12V DVR. I use this little $50 gadget from HobbyKing to record my downlink. It's a no-brainer, but can be a lifesaver when it comes to diagnostics.

    It can be set to automatically record when any motion is detected, which I do. I have an 8GB SD card in there, which is probably good for several hours of recording. I hacked up the adapter to power it off a spare 3S (11V) LiPo. It doesn't pull much power. I can run it for an hour or so on a 800mAh battery. It records in ASF format, which can be easily converted to .MOV or whatever.

    I use one from FPV Japan -- do you find that the video pass through degrades the video signal a bit?

    Yes, so my 'Y' split is upstream of this box, and I just connect up to the A/V OUT to make sure it's working, either momentarily or with a backup monitor.

    The only reason I use the video out from the DVR is that then I can confirm that the DVR is actually recording the FPV downlink -- it superimposes its own little record symbol and an elapsed timer.

    Good tips.
    I have never figured out why isopropyl alcohol pops hot glue loose. Mind you, I've never tried gluing plastic flamingoes to a microwave....
