UFO detector...?

[Nick Matkin]

Has anyone had any experience with UFO detectors? Such a device assumes a number of things, but anyway...

I'm going to build at least two types this year. For nostalgic reasons one will be from Flying Saucer Review, Sep/Oct 1968 (http://www.directorie.eu/news-THE_ELECTRONIC_UFO_DETECTOR.php) (If anyone is considering building it, there is a known error on the circuit, TR4 is shown upside-down.)

The other will be a much more modern design using a magnetometer and based on this design (http://www.imagesco.com/ufo/ufo_art2_pg04.html) which is probably a very similar circuit to those available on Amazon.

There are other designs out there I may attempt to build too.

As an open-minded skeptic it will be interesting to discover what they detect. Almost certainly just the natural changes in the Earth's magnetic field following a CME, but you never know do you?

UFOs supposedly are surrounded by strong magnetic fields - at least that was the thinking in the 1960s and 1970s when it was noted that petrol-driven vehicles but not diesel ones stalled during a close encounter. But perhaps UFOs have changed their propulsion mechanisms since then...

According to Flying Saucer Review, there was supposed to be a 'network' of the detectors across the UK in the late 1960s/early 1970s contributing to research. Presumably nothing came of this or we'd know about it. Seems to me such a network would be easy to do now that the majority of the population is online, and may actually discover something useful.

So... has anyone bought one or made one in the past 50 years? Any thoughts?

OC71 ? .... Oh, boy I remember taking those out of old radios as a young teenager when I had no money to buy new transistors.

I wonder what happens if e.g. a police patrol car passes by while using their mobile transceiver ... it will probably pick up those
EM signals in a broad spectrum too. Perhaps it needs a low-pass filter to get rid of the EM smog to eliminate false detections.
But will quasi static (my assumption) magnetic anomalies be picked up by a coil ? Or do you expect a frequency component ?

What would be typical for a flying disc presence?

I've read that night-vision glasses can detect many flying objects that we can't see in visible light. This makes sense to me because my experience indicates that UFOs are very capable of cloaking. Question: if a detector detects a cloaked craft and shows a magnetic anomaly, how do you know what you've detected? Sounds like an interesting project, and I hope to hear how it works out.

@ Operator: Well, like I said there are an awful lot of assumptions here! I doubt it's particularly sensitive to RF - in fact I doubt it's particularly sensitive to anything!

Germanium transistors - yes, you must be about the same vintage as me.

Incidentally, apparently there are people who think that point-contact germanium transistors were back-engineered after Roswell, simply because they first 'appeared' shortly after the crash. Imagine, an interstellar space craft using germanium transistors!!

Some folks have absolutely no idea...

@ Greenguy: I've had prolonged access to night-vision glasses. Yes, you can see stuff not visible to the naked eye, but I only saw stuff like satellites below the threshold of normal visibility, and very faint meteors. However, some observers using them report seeing objects that do 90 degree turns, sudden stops, and circles, all of which require explanation.

Do you guys ever wonder if the neutrino observatories double as UFO scanners?

@_@*

We already know that they double as nuke detectors.

Just like another poster said, the only thing I am aware of is those night vision goggles Ed Grimsley uses.

Well, my UFO detector is completed, and based on the 1490 compass sensor. (http://www.gel.usherbrooke.ca/crj/Documentation/sensors/compasdigital1490.pdf) It easily detects the magnetic field from a magnet waved about 2 to 3 feet (nearly 1 metre) away.

All I need now is for a UFO (whatever they are) to demonstrate that they actually produce a magnetic field that is detectable with a compass-like device. There is plenty of info to suggest they do have strong magnetic fields (able to stall petrol cars, but not diesel cars in close encounters - allegedly) so I must wait and see...
