OK, so you plug a $20 dongle into a Raspberry Pi, hook some stuff to the GPIO connector
and with probably minor tweaks to something like RTL_FM you can use it as a radio in
radio-controlled model planes, cars, boats. Add the Pi's $25 camera and you could
have a radio-controlled camera, useful for sending up in a radio-controlled plane or doing
wildlife photography. If you've got some analog (pulse position) channels those would
be good for rudder, flaps, various camera settings. This can be done in the 27 MHz CB
band or with a ham license in something like the 6 meter ham band. I had no trouble
getting RTL_FM running on my Pi but it probably doesn't have enough CPU horsepower to
do a lot of processing on the dongle side and on the imaging side at the same time.
Anybody done this?
