Your Cell Phone, is it capable of WiFi.
I have a BlackBerry Bold. It is set to connect by WiFi automatically to my Router at home and then the Business and as well at my Parents house.
NOW, how to make the router let X10 know that you are out of range and when you do get back into range.
Hold on, How about hacking an invisible fence kit for dogs, you know the ones that zap them or something when they leave the parameter of the yard.
Well, only an idea
to get more wheels turning.
Seems that is very easy to do around here.
I am trying to make a directional sensor.
Let's me know when I enter an area or leave an area by using the direction the person is moving.
I need to put 2 eagle sensors side by side and restrain the viewing area of the sensor to see only strait out and parallel to each other.
Need to lessen the repeated signals from a room sensor eg Bathroom.
no need to keep repeating a signal for the period of time you are there.
