[Geo]

Thanks Dragomir.
So i have two versions of OBMD-1 and it miss me the OBMD-2.
Maybe a good friend to send it to me....

Hi Sneshko.
I post a photo from the coil of cryfton.
Do you see any circular coil or OO coils with critical null????
THere is only one square coil....

[dragomir]

Geo, is this an orginal device?

[abdou2014]

Thank you Geo. what is its inductance ?

[abdou2014]

Excuse me Geo, I did not follow your advice

Ha, ha...! Very good Geo!
Thanks!
...Аnd, Is this PCB from OMBD-1 or 2 ???
Thank you in advance for the answer!

Yes, OBMD-1

Thank you Geo. what is its inductance ?

I don't know, not critical.
You wrap 30 turns and play with the capacitor

The pcb photo is the first pcb for OBMD1.
Constructor had attach to a Greek forum.
Look at top where is writes "antenna". It uses this track as antenna and this is what shows at schematic as coil with critical null

[abdou2014]

Is it a coil stimulator, what are the values, can we know more about the IR sensor ?
Thank you !

[dragomir]

I feel like this infrared sensor is used to protect against opening the box.

Geo, I did not see the second antenna in the picture

[GOLDEN LILLY]

The second antenna is not a coil, it is a in a form of a trace in the pcb(worded ANTENNA), it is connected to the input of the main coil via capacitor. This antenna is dependent on the PIR sensor. Look at the picture in the first page on this thread...
I have a complete schematic, pcb for this project...
