| I basically want to take an X10 MS10a or a DS10a security device and modify
it to transmit a "here I am" signal about every 30 seconds.
I thought about using an Eagle-eye and using the on/off buttons, but those
could be mimicked too easily. With the Security devices the random number
code will keep the false to a minimum. (actually someone else's idea)
I figure a door switch (DS10a) with a monstable feeding a mini relay would
be pretty simple....
Any one got a schematic for either the DS10a or the MS10a?
What am I going to use it for....
I am going to put it in my car and the non-stable will be driven by the dash
light circuit.
Signal... the garage door should be open...
I am either in my garage getting ready to leave, or coming in...
No Signal... the garage door should be shut....
Either the car is in the garage and turned off, or I am out of range....
As I also have a directional driveway sensor, I can double check when it
goes off to see if the "pinger" is in range and the state of the doors...
Any one got either a schematic or a better idea ?
Bob
