Serbian "Most Wanted"

[walkman]

Thank you very much for your reply Mr walkman,
I apologize

The picture I sent was not clear

I mean the diode below

The owner of this pcb is İvconic. You can use 4148 as diode.

Can you post a pcb with components, I've been looking for this version for a while, thanks

Cezar 80vpp /tx

This is the first time I've seen this version of CESAR.

Thank you very much, Orbita, for sharing this LAY file.

If it's not too much trouble, do you have the schematic for this PCB?
Can the same coil from the Servio más Buscado (SMW) be used?
Although I see that some components are hard to find, like the IFD120, IRFD9120, and CA3096.

OH!!!! a CESAR generator

Where you marked +5v is 10v and - 9v is - bat. I have a scheme with the modification of the transmitter, but with three channels, the third ch is used for the pin point, and here I drew only the transmitter with the change to rx ca30xx, it turned out to reduce noise compared to ordinary transistors, because in the CA case all the transistors are of the same gain and the beta gain, as far as I remember, is approximately 230 to 270.. I use a coil in the tx with 40 to 45 circuits, wire thickness 0.45 - 0.50mm in RX is 1 40 circuits wire thickness is 0.25mm. For coils with a diameter of 27 cm. The oscillator works as a resonant one. Resistor between the comparator 22k, it is best to first put a trim potentiometer of 50k and determine the correct value, then put a fixed resistor. It worked great for me with 22k the oscillator can reach more than 80vpp but I didn't notice a significant increase in depth if it goes over 80vpp. So I set the vpp limit to be 80vpp max.

Do you have a video clip of Cesar detecting a coin in the ground?

https://youtube.com/shorts/BIN0eoTV_...uSPkEvFrnzR8_9I also have it in the country, but somewhere on the flash memory I deleted a lot of recordings from the channel, but it works much better than many famous famous brands.I made the bipolar only with a large concentric coil of 50 cm.. For larger deep targets.
