|The primary work that must be done to
the Panasonic camera to make it airworthy is to encase it in a protective
enclosure and devise a way to attach it to the transmitter. Before
we enclose the camera, however, we'll solder a short copper wire about
1 inch long to one of the holes at the corner of the pcb board. This
is how we get a good ground connection to shield the camera. (more details
| In this picture you can see the
first step I've taken to protecting the camera. A small square of
balsa wood was CA's to the bottom of the circuit board. I tacked
it in place by putting CA on a couple of the tallest components.
It doesn't have to be hurricane proof, since a protective cover will be
added later. The top balsa cover was made by making to 'C' shaped
bits and laying them on top of the circuit board such that they wrapped
around the len housing. The bottom balsa cover has one corner cut out to
allow the header (where the electrical connections come off the board)
to remain exposed. All the balsa bits were lightly CA's into place.
|The next step was to wrap the camera body
in some sort of insulated material. I used some econocote which is
an airplane covering material, but you can use some electricians tape.
I tacked the material down all around the edges then hit it lightly with
my heatgun to shrink the cover, and then cut a small hole to expose the
header. Note that the short copper wire we soldered on in the first
step is sticking out of the covering. I poked a small hole through
the econocoat before applying it to the camera, and threaded the wire through
|The last step is to shield the camera.
I bought some muffler tape, which is a pretty heavy grade aluminum tape
with adhesive on one side. Cover the entire camera body with one
layer of tape, and be sure that the short copper wire is still sticking
out! Once the body is covered you will wrap the copper wire around
the camera body so it makes good contact with the aluminum tape, then apply
one last bit of aluminum tape over the copper wire to hold it down.
I've found this method to provide a very vibration-proof way of shielding
