Good job Eric Page. Some aircraft owners and/or builders will appreciate your
work.

Eric & Alec,
> Once we hear from Wade that his EFIS and video adapter handle the camera feed
switching OK, I'll edit the schematic and work on a board layout.
Just wanted to let you guys know I hooked up 3 cameras to the switching unit that
you recommended Eric and fed it into the GRT EFIS via the switching unit's
RCA jack out into the USB adapter.
The switching worked fine, albeit their is a VERY brief (less than half a second)
skewing of the screen as it goes from one video input to the other. You have
to be looking right at it to see it.
Again, it all looked fine to me. If we could eliminate the skewing it'd be nice,
but definitely not a showstopper.
Cheers,
Wade

I'm glad to hear it works OK and the EFIS doesn't lose sync on the video signal.
Thinking out loud here... the brief skewing you see may have something to do
with the mechanical switch. Perhaps it's a break-before-make type, so for several
milliseconds there's no signal present. With the switching done electronically,
the loss of signal will be reduced to a few tens of nanoseconds, so
that issue *may* disappear.
Eric
