Hello. My name is Christopher, and I am with Flathead County Search and Rescue. I am on the K9 team, and one of the problems we face is knowing exactly where our dogs are when we are out in the bush searching for people/victims. We use Garmin Rino radios that have peer to peer GPS polling capabilities. I would like to strap one on our dogs so we can monitor their exact location. The problem is, you can only transmit this info one every 30 seconds (FCC Regulation). So I need to build a timer that will send out a pulse (pos or neg) for one second, every 30 seconds. I was thinking of using a 555 or a 556. All of the info I find is one a continuous pulse output. (Which will not work for this application) Can anyone help me out with the needed components to accomplish this task?
Thanks so much!
