I know something like this was asked about in the past. Figure I would see if technology has improved..
I want to make a "small" battery operated device I can placed, and it transmits (pings) another device attached to me (like an old pager). If I get say more that 50 feet or more away, the device placed would will let me know. Siren or something.
Any ideas. Sounds like I am trying to keep track of Grandpa.
Maybe an FM beacon that pings the device on me (in an old pager) and when no response back to the placed device, it uses that old pager protocol to beep the pager. Good use for old pagers anyway.
I can attach it to the dog I sit for and if he gets to far and I get a beep and yell "get over here". I get busy and he knows it and walks off.
