Frequency discriminator and all-electronic receiver

[Mike(Mont)]

Here is a photo of the electronic receiver. You scan the area where the transmitter is pointing towards and narrow down the beeping until just a few clicks as you sweep past the target.

Nice design. Hope it will works according your expectations.

[Mike(Mont)]

Ah, another Tinker Toy fan. This "design" was one of those see-how-fast-you-can-put-something-together, part 2. Really needs some kind of "Star Wars" case to get people's attention. All that artsy-fartsy stuff is not my forte.

Hell
Dear all.

I received a pic. Its sender claims that it is a perfect detector. Is anyone that have some information about it?

[Mike(Mont)]

Two-way radio?

Mike, give us some info about this system (whatever you can share...)
This receiver actually can trace electronically the "target line"???
By the term electronically , i mean only electronics - (not electronically "assisted", swivel rods , pendulums etc...)

[HaFar2010]

It has only a prob! but it detects all targets using a radar program, which include their type and gps code for exact location.

If it not dig targets too - it is worthless.

Don't know if "signal line" tracing is an accurate description as that reminds me of walking an "S" pattern with L-rods. But "finding the line to the target" is looking/aiming right down the signal line (from transmitter) like down the barrel of a gun. So yeah, you have to move the receiver/antenna and find the anomaly, where the device sounds off, then check it out further for size, shape, from other angles. Something like a metal detector. The newer Gold Gun with the transmitter might be somewhat similar but never seen one.

[Bill512]

Mike, I guess that this TX/RX system it's the Magnacast configuration.

[Mike(Mont)]

Got the parts I ordered but haven't installed yet. I don't expect a huge difference, but many small steps add up. No, that black handle does not swivel. Wierd camera distortion like fish-eye lense.

Yeah, the newer Gold Gun and the Magnacast are similar. Haven't heard much success from either one. Pretty good indication when they quit selling them. Wonder if those guys went crazy?

[Mike(Mont)]

This is a transmitter coil I threw together today. Plan to go a bit smaller next one.

[Bill512]

Mike, I assume that the coil cable is an ordinary cable...nothing special or RF ,etc

[Mike(Mont)]

Yeah, LOL, you can see the red patch wires from the amp. Not quite "up to code", yet. Don't touch those.

[Mike(Mont)]

I built a smaller Tx coil.

What kind of antenna are you using to receive signal?

[Mike(Mont)]

Oh man, I feel like Edison inventing the light bulb-- ten-thousand ways that won't work.
Similar to the Gold Gun or other ferrite rod antennae.

Maybe this:

Can you share with us this TX/RX Mr Mike ?

[Mike(Mont)]

Maybe the translation is wrong. I said many frequencies will work.

edison didn't invent the lightbulb swan did, most of the stuff he is credited with "inventing" were actually invented by others, he just developed them or made them work better.
today he would be considered a patent infringer and sued out of existence.

[Mike(Mont)]

He didn't even do much of the work, just took credit for it. But his process and mine are the same--make every possible mistake.

[abdou2014]

can u share the newer Gold Gun schematic if the box are not empty pls ?

[abdou2014]

Is there anybody among the old members who knows how to make the double O coil 50 + 50 of esteban Pls ???
