Magnum detector against small coins.It just needs to be checked pcb I lay. No drawing, there is just a picture TX 1 MH RX 10 MH It is very stable and sensitive detector like Fisher Goldbug.

Hello cnckecgo
Could you show a diagram - let's make a comparison?

I love cats myself, we used to farm, people from the town would bring cats out to the farm country, and abandon them. A Pity!!!!!!! We let them live on our farm. They caught a lot of mice and ate them...

A black monster with glowing green eyes appeared in front of me!
I Tawt I Taw a Puddy Tat !!!

Hello Ruben
The coil is originally purchased. There are only minor changes, the oscillator is used according to the scheme in Tesoro Cibola at a frequency of 14kHz, at position U1 is TL074, at position D10 is used stabilizer 7805 as a reference for U11. I put a 1k Ohm resistor in series between the base of Q2. U10 consists instead of 4041 from two complementary transistors BD139/140. together with R89, I still have a 20k Ohm resistance trimmer included in the series to fine-tune the discrimination. The wiring basically works for the first time

My detector

Could you share the details of the coil and how you built it?
Also could you share the PCB you used and the schematic you used and the changes you made to make it work properly?

My detector

You show a completed detector, but you don't say how it works. Share the results.

Ha, ha, ha! I believe that Carl will be delighted with such a topic!
No, we won't talk too much about cats.
Except to repeat; no, of course I do not "hit" cats!
I was just "shaken" out of bed by the terrible chaos and "carnage" in the room!
The usual morning "game".
I take a sock and chase miscreants around the room with it and if I catch anyone; that one gets a sock on the head!
That's all!

OK. I understand. But please don't hit cats.

Best wishes

(Maybe there should be a new thread about cats)
