Pistol Detector - TOTeM (Complete Details)

[aft_72005]

Hi omar
yes , i agree with your opinion . but i remember my experiments for some years ago Tx and Rx on ferrite couldn't act as long range.

may be designer of totem had feedbacks from people that built and trying totem .

thanks Omar this one is defrent than TeTOM in this one RX and TX are in one frett road
and how long the freet road in this one.?.
in last tow day
i make ready the circuit

thanks how to delet this message

I apologize to you, my friend Anwar.
I did not understand your problem. I placed the drawing files open so that members could change as desired. The device does not accept calibration. You may need to flip the transmission coil (change the direction of the field), or the transmission power is high and needs to be reduced and the resistance value increased by 1 K.

Don't worry, my friend Anwar. I know the amount of effort it takes to create a device manually, the challenges with this type of device, and the disappointment when it does not work the first time. Or even when it works and its feasibility is discovered much less than expected, it is hope that makes us try and try. I wish you success in your life and abundant livelihood.

how to connect the test point

how to connet the test point I think with press switch and Ground

[omar]

This frequency measuring point is connected to an external device called a frequency meter. To adjust the transmitter frequency

thanks Omar between RX there is acapacitor on the PCB What value of that

[omar]

Capacitor value with coil inductance. Determined by the frequency at which you will operate. I advise you to use the original transmission scheme, as its value is set to 65 kHz. Especially if you are using the original version. Note that not all 555 timers provide a stable frequency depending on the quality of manufacturing.

yes omar your correct not all 555 timer provide the same frequency .. thanks my friend

Hi tell us some information about ferrite coils

Hi how many turns is the coil TX and the RX in ferrite and the .mm of the wire, thanks
