This unit will transmit live video from three sequenced cameras.
The1 watt pep 70 CM transmitter is a PC Electronics TXA5-RC .
A CCD hi res camera is pointed downward and is the first in the sequence.
Two Cmos cameras are used in the next two 40 sec.views.
8 AA Lithium battery pack provides at least 6hrs of normal operation.
2 D size Lithium batteries provide power for a 10k rpm motor driving a weighted wheel
for improved gyro stabilazition.
A zero drag thrust bearing upper support also improves stability.
Foam insulated for low temp. operation.
A 1/4 wave antenna is mounted downward on a foil ground plane.
CMOS switching of three reed relays provides camera steering.

Top View
The black box on the top is the gyro cover. The black box on the left side of
the picture is the side looking camera. The black box on the right side of
the picture is the down looking camera. The bananna jacks allow you to check

Bottom View
You can just see the top looking camera at the back of the package. Note the
metal foil ground plane on the bottom of the box, and the 1/4 wave 70cm antenna
in the center, and four stand off legs that will hopefully protect the antenna
and possibly allow the video signal to get out after landing.

Inside View
The up looking camera is on the left. The down looking camera is on the right.
the side looking camera is on the bottom. The PC Electronics transmitter is
on the left. The D cells that power the gyro are the big black object at the
top. The video battery pack is wrapped in white foam, and is located on the
right side. The circuit board at the bottom is a custom designed timer system
to sequence the cameras. The red and silver wheel is the gyro wheel. The hook
that is sitting on the gyro motor is used to suspend the camera package from
the rest of the stack.
