- Each slave will be equipped with a microphone and a speaker. Communication will be through a call/response sort of deal. I'll have to get some hardware built before I can experiment and figure out the best way to do this. I may need to add IR sensors to keep everything synced up...
- Master will be in charge of recording a waypoint when any slave is clicked, as well as the distance to said slave, tyhe name of the slave and any other relevant data like current time etc etc.
- Everything will have to be robust for use in the bush, and low power enough for long sampling trips. Solar charger anyone?
