OK, John, here it is. It can be constructed for the price of a 12v
|
|||
|
|
battery, a door buzzer or bell a magnet and some wire. The housing is a large
|
|||
|
|
jar such as institutional size foods come in. The base is a simple wood block
|
|||
|
|
and the strut can be a coat hanger. The rest should be self explanatory, but
|
|||
|
|
if you have any questions, feel free.
|
|||
|
|
|
|||
|
|
The magnet is delfected by any strong magnetic field, such as that which is
|
|||
|
|
proportly produced by a UFO. If the field is strong enough, the circuit is
|
|||
|
|
closed and the buzzer sounds. The loop shouldn't be more than 1" in diameter
|
|||
|
|
and the wire should be as thin as possible depending on the battery you use.
|
|||
|
|
The beauty of this is it will not make a sound if the UFO is an airplane or AF
|
|||
|
|
test craft, unless they are using exotic power supplies.
|
|||
|
|
|
|||
|
|
One downside is the device is not very portable. It must be stationary.
|
|||
|
|
You can add a switch to turn it off during transportation if you are moving
|
|||
|
|
from site to site very often.
|
|||
|
|
|
|||
|
|
Have fun!
