Since you are going to intelligence in this box, add another circuit to
this that will set off a local audio alarm 1 minute or so before the
dialer does its job, as a reminder that the dialer is about ready to
report you MIA.
Thusly spake Paul Mele:
> OK, let's get a bit more techy...
> Set up an automatic dialer with the number of someone you trust, etc, who

> Set up a "dead man" timer for the "RESET" interval you'd be comfortable

> timer for 5 minutes....
> Have the machine use a digital recorder chip (8 seconds long...cheap at the
> places listed for "grain of wheat"bulbs earlier)..."Warning..Reset Deadman
> in 5 minutes or less"...so you don't get distracted and lose track of time.
> Push the Deadman button every "RESET" minutes, or it calls your emergency
> contact. They verify by calling you back, then they call 911.
