Floater

This is still very much a WIP.
Some of the code works.

Dependencies

• Imagemagick
• Direwolf

Punchlist

• mux control logic
• turn on radio, activate ptt
• stream gps data
• get serious about some tests and project structure.
• convert gps data into state
• figure out correct APRS destination and digis.
• generate APRS telemetry messages.
• generate APRS wav
• collect gps to object
• collect temperatures to object (wire in 18b20)
• send APRS wav
• physically connect sound to radio.
• capture image
• image to wav
• create sstv reception station.
• send image as sstv
• improve message quality on sstv picture.
• more tests
• cruise detection
• descent detection
• preflight check for devices.
• video capture is not happening according to schedule.
• battery meter solution (for desperate measures)
• logic around emergency shutdown, power-up etc.
• automation around initial set up:
• floater starts on boot
• floater reboots when things get really bad
• configuration file.

Run things on the tracker

Get things there:

scp -r floater/*.py *.txt *.md pi@192.168.86.32:/home/pi/fc/

Run it:

# maybe update the venv:
source /home/pi/tracker_env/bin/activate
pip install -r /home/pi/fc/requirements.txt
PYTHONPATH=/home/pi/fc/ /home/pi/tracker_env/bin/python /home/pi/fc/flight_controller.py --init

Other options: --test-gps, --test-vhf

Copy images and stuff back:

scp pi@192.168.86.32:/home/pi/Pictures/photos/capture_0139.jpg ~/Desktop/test_photos/

Using Direwolf is cheating

I know. I have a branch that has a native
APRS + AX.25 + AFSK implementation, but the wav files that get generated are worthless. :(
