Dragomir.. if you have other photos to post here send them to my email and i will resize and attach them here

Part list next week. My opinion is that the IR iss doing NOTHING so you can find the value from other parts at Andy Flind thread.

Dear Geo!
This week passes ... You promised Part List for the scheme you set ...
I do not want to offend you - I'm just a little impatient...
Regards!

This project has been frozen for 6 years. The device is working in general, but I could not handle its settings. Can anyone tell me what frequency does the receiver and the induction oscillator work?

Here another photo from this beautifull lrl by Dragomir...

Sorry i am busy.
I started to write and did let it...
Today morning i updated the schematic with parts but only for IR section, beeper and preamplifier. All the other are the same from Andy Flind magnetic field detector. So maybe tomorrow i will check it again and will post it here....

What do you mean induction oscillator???

Mr Dragomir , can you detect magnet with your LRL ?

[GOLDEN LILLY]

There is no induction oscillator in crypton OBMD. It is purely a passive LRL...

I agree, this is the reason that i asked Dragomir...

[dragomir]

the infrared sensor controls the power supply of the IC7. IC7 acts as an excitation generator and is inductively mixed with the signal received by the receiving coil.

[abdou2014]

I think it's the mixing point between IR oscillator excitement and receiver ?

dragomir I had no answer ???

[dragomir]

The IR manages a transistor that turns on and off the power supply of IC7. The IR does not participate in any process. When the device box opens, it blocks the operation of the IC7 and the excitation generator stops working. This is probably done so that the principle of operation can not be traced when the device opens.

abdou2014 i think this is the oscillating antenna but this is done for you in another way

[dragomir]

My LRL does not work because I do not know how to set it up. I remember detecting a 3-meter monitor, but it works only as a receiver without the excitation generator. now, if I remain free, I can experiment with it
