UFO Detector Plans?

[Pygar2]

A friend is looking for a Sixties UFO magazine he had, with plans for a UFO Detector. He recalls it being a b/w magazine, somewhere between a tabloid and a trade paperback, with "Flying Saucers" in the title. He built the thing! It had a mag compass, and a tremble switch, a #47 bulb, and a 6-volt battery. It would detect trains half a mile away. I'd like to find this for him so he can build another. Ideas?

Method A: The Modified Compass Contact
In this direct assembly, you turn the compass itself into the switch.

• Prep the Needle: Open the plastic casing of a cheap, liquid-free magnetic compass. Tie or solder a micro-thin, highly flexible bare wire to the center pivot of the metallic, magnetic compass needle.
• Set the Contact: Glue a tiny, bare copper wire or pin right next to the path of the needle (often set just a millimeter off from Magnetic North).
• Complete the Loop: Wire the needle's pivot wire to your #47 Light Bulb and the copper pin contact to the 6-Volt Battery.
• The Result: When the device is completely still, the needle rests near North without touching the contact pin. If a sudden magnetic anomaly or vibration shakes the needle, it swerves, touches the pin, completes the circuit, and flashes the #47 bulb.

Method B: The Trembler Switch Combo
In other articles, a commercial trembler switch (a small metal tube with a loose internal spring or metal ball) was mounted directly flush onto the base of the compass.

• Align the compass to Earth's magnetic north and allow it to stabilize.
• Wire the trembler switch in series between the 6V Battery and the #47 Light Bulb.
• Because the trembler switch is incredibly sensitive, any sudden structural vibration or frantic physical oscillation of the mechanism (attributed by hobbyists to spatial disturbances) shifts the internal ball, instantly bridging the gap and lighting up the bulb.

Flying Saucers, Ray Palmer's zine, may have had such ads.

Our former cohost, the late Chris O'Brien, was involved in such a projec. His friend and colleague , filmmaker Ron James, is booked for our September 13th. I'll ask him about it.

I was in touch with Ron after Chris' accident a couple of times. Chris is still listed as their Media Consultant.
