Lrl from Italy

[brs]

Dear Franco, I want to know the size wire Alantina

[FrancoItaly]

It's normal insulated plastic wire, I think about 0.5 mm, no critical

Thank you Franco

franco My question was about the circuit not antenna.Which version of lrl is the best.circuit 8mhz or with 4046 or....?
this is my box with mdf layout.with stylus antenna

Greetings all, I asked for a little help at all here on this forum for the construction of a lrl, since I'm not much good at electronics, but to my great regret, no one has seen and no one helped me, they all have made changes, they all mounted the rl franco italy but no one helped me step by step.

Hi mustefa ubram
All my Lrls, self-oscillating stage, CD4046 or quarz oscillator, they have same sensibility, but the first is very difficult to build, the second (phase measuring) is difficult to test at home (almost no change if you touch the input antenna), and the quarz oscillator type changes the output voltage when you touch the antenna, this is the proof that all the electronic parts work well.

ِCorrect my dear Franco

This is the trust

Thanks you are Gread ( tu eri in gamba )

Hi Mustefa nice work my friend

but you know what I need to try also this PCB heheheheh

and you know my email

Good luck for testing your device

Hello Mustafa good job Is it possible pcb black and white

[FrancoItaly]

Hi mustefa ubram
Good work, the pcb is very important because parasitic capacitance may influence the output.

Best Regards

Hi All

I would like to give some suggestions for the use of my LRL, you must seek facing north and with the antenna parallel to the ground and moving it from left to right and vice versa. My type of LRL is no motion so the signal does not decrease if you hold the antenna stops. When you get close to the target you need to tilt the antenna to get the signal again and when you're right over the target signal disappears. The human body can shield the signal if it is between the target and the LRL. With the stylus elongated up to about 1m you can get a kind of pinpoint, but in this way increases the sensitivity also to the compass effect. Perhaps the stylus antenna is the most versatile of the antenna coil.

Best Regards

HI TO ALL
today my lrl finished
my lrl Responds to mobile signals.I used the circuit between the antenna and the spiral coil.I think the coil is more sensitive.MDF is the best ingredient for making.Plastic body in any way is not recommended.Electrostatic makes a lot of noise.Increases the voltage output When the mobile is close to the antenna steel.I did not test in real mode Outside the Home

Mustafa corrected Pin4 lm358 A
and I do not see C7 and C8 on Pcb

hi mustefa
Please take a video of the test device
Thanks and regards

yes.I have corrected pin4 and later built.my lrl working ritgh according to franco.mobile signal response

Hi Mustefa Good and nice LRL project. but tell me you have test it near TV and pick

If yes what distance? and test him in magnetic field for buried metal

I put here your video version Youtube

http://www.youtube.com/watch?v=5syhk...ature=youtu.be

thanks and look at you box I have send you email

hi nicolas.tank you.yes i test with tv but not distance Anything.Only responds to mobile signals.It should react to the TV?(My TV system is LED)????
tank you for youtube version
I SEND FOR YOU GMAIL

[mustefa ubram]

franco When I'm touching the antenna .The lrl does not show any reaction.Is this normal?
Only when the phone is close to the circuit shows the reaction.When mobile is close to steel antenna is no reaction.is this normal?

[FrancoItaly]

Hi mustefa ubram
If you are referring to quarz oscillator type when you touch the antenna input the output dc signal decreases slightly and if you turn P1 for led on and touch the antenna input the led go off.

Best Regards

[SIZE="<font><font>6</font></font>"]hi all
I Thank all our teachers for their good ruffle and exchange their experience notament mr nicola and Franco italy and of course all the others and that my testing of pcb lrl by Franco italy[/SIZE]

[FrancoItaly]

Hi mustefa ubram
In your Lrl there is a spiral coil that is between the input and the stylus antenna, this is not in my design, perhaps it may be useful, but it could be not useful. Perhaps the phenomenom doesn't cross the spiral coil.

Best Regards

Yes I m agree with you Franco and is correct what you said. But need tested that in full area when we have buried metal
