We are building a 21st Century Message in a Bottle (or flat case if necessary) as a community project on devRant.io. We are 20,000+ software developers but fairly new inexperienced Makers.
The drifter will be put in the Gulf Stream off Cape Hatteras late March 2017. The goal, if we are fortunate, is Europe. We are building apps and desktop environment to track the vessel. That is the easy part for us. We will be sharing any code we create.
We will either use a 1 Gallon clear plastic PET bottle with a 4.5" opening or if necessary flatter surface container that we can easily get wider specifications. Whichever, must be airtight and waterproof. We are in the midst of testing options right now.
Thinking of using:
Arduino or Rasberry PI Zero
Iridium RockBlock, Stingr or alternative to track the vessel.
Solar cell - 6v/2w
Possibly an Accelerometer
Has anyone in the forum done this? Do you have advice you can share? We also have a Slack where we share info and testing videos.
