Dowsing Rod for 2012

[Geo]

Hi Fred,
It appears the 4017 is serving only to insure the output remains at 10% duty cycle as you adjust for different frequencies with R6.
I suppose you could re-wire the 4017 with a CO jumper to change to any other duty cycle in 10% increments.
But from what I see in the circuit, it was probably found that 10% duty cycle was good.
I am guessing it was set at a constant 10% to prevent the duty cycle from changing from maybe 1% to 99% if you adjust R6 through a large range of frequencies.

Depending on the impedance of L1-C5, it appears this is probably a low power oscillator.
I am thinking the radiated power will change as the frequency is changed.
I wonder where the other parts in the box connect?

Hi J_P.
Yes, it is a low power device
I did not measure the radiated power but i believe that it is not stable with the frequency.

Here is the pcb....

Thank you, Geo
Please give a list and description of parts and machine work. And how to build windings?
It can make clear to the radius and depth?
The metals in the soil under the Sense?
What is the reaction of the metal Sense?
The coil is wrapped around the telescoping antenna?
What is the size of the telescopic antenna?

[teknoloji]

Why do you waste of time to no avail.
LRL to do the project, why not a serious breakthrough.
Why not migrate to the review of the basic rules.
With this circuit can not detect anything.
in the cave with the empty bar and magnetic detection or water line breaks do not need to start .
a transmitter circuit. Where the recipient.?,
How do you understand how to turn back to 70Hz sent ok ...?
rod returned the left returned the right.? rod, the same reaction just do.
I think the discussion on real project

Hi teknoloji,
This circuit is not designed to be a detector.
It is designed only to produce an adjustable frequency from 3 to 70 Hz only.
It does not detect anything.

This was made for people who want to use dowsing to locate buried metals.
The designer of this circuit says he can locate gold, copper and aluminum if he dowses for the metals when this transmitter is turned on.

For me, I have never seen any success for dowsing when a transmitter is turned on or when a transmitter is not used.
So I do not use my time to build this transmitter.

Hi Geo,

I am wondering what the brass and steel part on the outside of the box are for (see image below).
What is their purpose in this transmitter? Also, how are they connected in the circuit?

Other questions:
1. How is this transmitter used?
2. Does the transmitter connect to dowsing rods or to a ground probe?
3. Is the transmitter held in the hand, or is it placed at a distance from the dowser?

This is a free project.
If you don't know to use a Lrod then let it.
Also if this is waste of your time then read something other project. This is not for you.

About winding i wrote at begining.... you must wind 280turns onto the antenna as at photos. I put a paper onto antenna and after it i wound 280 turns on one layer with wire 0.15 mm diameter. That is all.
Antenna is 80 cm long.

tank you very much dear geo
Please answer my other questions about this device
1.please give a list and description of parts and machine work?
2.To what depth and distance can detect metals?
3.When it detects that the metal reacts?
4.I also recognize that new metal?Or is the only metals that traditionally defines the soil?
tank you
best wish for you in new year

Hi Geo,

I am wondering what the brass and steel part on the outside of the box are for (see image below).
What is their purpose in this transmitter? Also, how are they connected in the circuit?

Other questions:
1. How is this transmitter used?
2. Does the transmitter connect to dowsing rods or to a ground probe?
3. Is the transmitter held in the hand, or is it placed at a distance from the dowser?

Hi J_P.
1. You turn the swich to on and the transmitter works.
2.Transmiter is connected to antenna via the L1.
3.Transmitter is inside the plastic box. You don't keep nothing, only the handle of rod.

Tommorrow i willl try to draw a schematic of how all are connected.

Agree with your opinion.
This put a handle is missing.

of course you allow.
I have wasted time to spend alone in labor.

I see,
I found it strange because i would have used this kind of circuit...
