I'd like find out where my cat is when he is prowling around the neighborhood.
My plan is to attach an RF transmitter on his collar and use a home computer & google earth to plot his movements.
What parts do I need and any suggestions are welcome as are pointers to similar projects. I can't spend too much money so gps is too costly. Accuracy can be +-3 meters.
I am thinking along the lines that maybe I can't cut down in size an Arduino or Raspberry for his collar. I probably need a few boards with rf receivers attached outside to select fixed poles to triangulate his position
