Cloudy but clearing up
Good Morning Augusta. .
This morning it is overcast with a chance of rain in the morning, then
mostly cloudy. Fog early. High of 55F. Winds from the SSE at 10 to 15 mph.
Chance of rain 50%.
Tonight it will be partly cloudy with a chance of rain after midnight. Low
of 39F. Winds from the SSE at 5 to 15 mph. Chance of rain 20%.
The readings outside right now, taken from my own weather instruments:
a relative humidity of 86% with a Dew Point of 48.3ºF.
The temperature is 52.8ºF with a very low wind chill.
Presently we have West Southwest winds between 4.5 mph and 9.3 mph.
Our Barometric pressure is 29.39 and fallinging with a weather graphic
indicating rain.
We had precipitation overnight of 1.85 inches, with an overall storm total
here of 4.49 inches.
Visibility is 10.0 miles with clouds to 1,000 feet and overcast to 1,700
feet.
In recent months I've posted "how to build…" items on this blog everything
from hot air balloons to solid fuel rocket engines. So, I thought I'd get
"out there" a bit today just for fun.
How to build Your Own UFO Detector
The device is a crude but fairly sensitive magnetometer. The theory is that
an alien UFO would travel with some sort of advanced electromagnetic
propulsion, it would disturb the magnetic field and the sensor would detect
it. It's a simple trembler switch, you can make it yourself with some wire,
a magnet, and a doorbell.
The entire switch is about 6 inches tall, made from 3 pieces of uninsulated
solid copper wire. The illustration found online shows the general layout of
the switch, with the two sides of the circuit indicated in blue and red.
It's a simple pendulum hanging from a hook, and down through an open loop.
When the pendulum swings, it will hit the loop and complete the circuit. The
pendulum's counterweight is a small magnet, you can use a cylindrical
refrigerator magnet and wrap the end of the copper wire around it. The
magnet isn't part of the electrical circuit, but when a large magnetic field
moves by, it will attract the counterweight and cause the pendulum to swing.
You can verify this by waving a magnet near the sensor, the pendulum will
swing wildly, and will be influenced by a moving magnet even at a fair
distance.
Make the hook about 6 inches high and the lower loop about 1/2 inch in
diameter, and put it under a glass jar so that it won't be triggered by
drafts. Connect the bottom end of the loop to one wire of the doorbell,
connect bottom of the hook to the other wire, hang the pendulum on the hook,
yes, you'll need a power source for this, and your UFO detector is ready for
action.
You can increase the sensitivity of the switch in two ways; you can increase
the length of the pendulum, or decrease the size of the loop. You could
actually make this several feet tall, and it would be so sensitive it could
detect nearby electric motors and TVs, and it would be very sensitive to
vibration. But we're trying to detect huge metal spaceships so we should
start fairly small. And it turns out that even a small detector is very
sensitive.
NOTE: This design has been around since the 1960's in one form or another,
so if you do a web search for a UFO detector, you'll certainly find one.
NASA spends how much looking for flying saucers these days?
