Solve the circuit...

It is a head phone tester. Ha Ha

Carl I have to say you have my attention!

Well, time to pull back the curtain...

Qiaozhi nailed the first question... I call this a "Rapid Discharge Oscillator." When the pushbutton is pressed, the coil is energized, which puts a dead short across the battery. Due to the internal resistance of the battery and the near-zero resistance of everything else, the battery voltage will drop to zero, releasing the relay, and repeating the cycle.

So the relay will oscillate, and quickly discharge the battery. I measured a couple of 9v alkalines, and the short-circuit current was about 3 amps, so this circuit will discharge one probably in 15-20 minutes. No doubt there is significant arcing on the relay contacts, so this circuit has a real risk of getting welded stuck in the shorted position, and causing a dangerous meltdown of the whole thing.

The headphone jack is where the dowsing rods plug in, so if you simply touch them together, the Rapid Discharge Oscillator is activated.

And Qiaozhi nailed the second question... with a little help from Dell. Yes, this is the little accessory box that was sold by Dell along with one of his LRLs. It was sent to me on loan.

Now, the real question...

"What is the purpose of this circuit?"

That is, of course, a question for Dell. Now I'm sure that when Dell sold this device, he didn't say, "Here's a little black box that makes a cool buzzing sound when you press this button." Instead, it might have been, "Here is a device you plug the dowsing rods into, and when you touch them together, it does such-and-such."

It is the such-and-such I'm interested in.

Dell, is this device garbage, or does it serve a Useful Purpose?

When you field tested the unit, did you experience a mild shock, or tingling in your hands when you walked through the "field" of the signal line leading to the target? Dell

Ah! Now I see what plugs into the jack socket, it begins to make some "sense".
It provides the dowser with a kinaesthetic response when the rods cross over and touch. I suppose it does enable you to look where your going instead of staring at the rods. Saves accidently walking into a crocodile (sorry - couldn't resist it!)

I guess the loser in this “game” is the poor bloke who gave up his hard earned cash for this gizmo

No, not at all.

Could be the purpose, but a later incarnation of this circuit, the "Magnetic Wave Guide Receiver" (see the VR800 report), has no buzzer. An LED lights up when you touch the rods together. I guess you could strap it over one eye...

OK, Dell... what is it for?

Carl, according to your description of the device, I am not the manufacturer. It would be dishonest of me to accept credit.

But, for you to intentionally infer that I am the manufacturer is to lie.

I see by the mocking that a few others share your mentality for promoting deceptions to keep you from having to apologize. Dell

[ivconic]

The point is...


* But those two i..... are less i..... than buyers of LRL's,*
* because they saved money, at least!(telephone cable and *
* stupid plant are not expensive). *
The main point is not to waste money on frauds!
Dell i'll be very sorry if you understand me wrong....I am not claiming that you
are fraud.....at all! We all trying to survive these hard times, earn some money....If we all closer i'll call all of you to some pub and have beer with you!

Sounds good to me.
But I don't want that beer with the chilli pepper in it.
Some real ale would be better, or even Qing Dao (Tsingdao) pijiu!

[ivconic]

Guiness !!!


I rather prefer Guiness....although Heineken and Bud can do a job as well!
Afer that final match France-Italy....all i need is packet of very cold beer...
the hell with detectors and nuts!

Ivconic, I appreciate your clarifying that. Thank You! It is the motive and and agenda of my Skeptic cult accusers that is questionable.

I don't drink, but I would be proud to come to the pub and shake your hand.. My kindest regards to you. Dell

Your normal modus operandi is to blame someone else for everything... maybe that electrical engineer you paid $40/hour. I do know for a fact that you sold this particular device, so if you don't have the moral fortitude to stand up and take responsibility for horrendous piece of junk, then this will be no surprise.

I see by the mocking that a few others share your mentality for promoting deceptions to keep you from having to apologize. Dell

What do I need to apologize for? I said the stuff you sell is garbage... it's true.

- Carl

[Dell Winders]

Carl, this is what you now say you said

What do I need to apologize for? I said the stuff you sell is garbage... it's true.- Carl

Carl, this is what you said. There is a difference between the responsibilities of a manufacturer that makes products, and an independent dealer who just sells products.

It was not an inference, Dell... you make garbage products. - Carl

Look at yourself, Carl. You are a habitual liar. You make up one lie to cover another.
Let me repeat, I did not, and do not build, or manufacture the products you are claiming I do. That is a flat out lie.

Your saying that I sold the product does make it true either, but if I did, let the person who purchased it from me come forward with their complaint, if they have one, and let's see if it can be resolved. My phone number is 863 422-5454. I live in Haines City, Florida, for the past 25 years so there has never been a concern for any customer with a problem to contact me.

When was this product puschased from me, by who, and what is the model & serial #?

O.K, Carl, you accuse me of making garbage, and selling a horrendus piece of junk. No customers have ever informed me of that. That's strictly your personal opinion, not a fact, and should be presented honestly as being only your personal opinion, least it may appear that you are hell bent on slander, and giving folks an inaccurate impression about me.

I was a White's metal detector dealer, and sold metal detectors manufactured by Whites. I sold underwater PI detectors manufactured by ELSEC,in England. I had the distributorship for the USA & Canada, for Radar Systems, inc, and sold ZOND Ground Pentrating Radar, manufactured by Radar Systems, Inc. I also sold Frequency Discrimination Locators, manufactured by Vernell, Inc. I even tried to sell Fuller Brush products. My name is also on a computer brand. But you know something, Carl Moreland, is one of only (my considered opinion) 3 skeptic cult idiots in the world who insist that Dell Winders, be held responsible for those products I have sold which were manufactured, and warranted by another company. If that is considered rational thinking for any business by any one viewing, or participating in these forums, I may have mistakenly entered the door to a Carl's Geotech looney bin.

Folks, I don't know of any independent dealer anywhere that is responsible for the content of a manufacturers product. I'm not sure what was meant bynot having moral fortitude, but if If any of you believe it is immoral of me to personally pay the cost of shipping & repair of manufacturers products long after the customers factory warranties had expired, then it is a matter of record that I am immoral.

If any of you believe it is immoral for me to tell any of my customers that if they aren't satisfied with my product after they have tried it, to send it back for a full refund, then it is a matter of record that I am immoral.

If any of you believe it is immoral for me to honestly inform customers about the limitations of the products I build & sell, before they purchase, then it is a matter of record that I am immoral.

If any of you believe it is immoral for me to have spent countless years of my time to personally instruct hundreds of LRL purchasers of all manufacture, and share my field experience to help them get the most benefit from their purchase, with never a fee, or obligation, then it is a matter of record that I am immoral.

Thank goodness everyone in this world is not consumed by prejudice and ego driven as Carl, appears to be.
