hello omar
I made an application suitable for your project but with pcb holes. I could not solve the LED situation. It seems to work. There is detection as the tx power is reduced and the frequencies change. It is a workshop environment, not a natural environment. |

Frankly, this modification needs the support of someone who has successfully tried the device with a similar modification. For example, how much transmission power is appropriate for capacitively coupling the coils with the ability to balance and adjust the threshold. Is shielding the sensing phase binding? What is the correct direction of the current in the two coils? presented to you the idea and the path others took in developing it, and it seems that they succeeded in the operation process. Now it's up to you to try it. I hope that whoever succeeds with this amendment will help the rest of the members.

Hi
does the totem really work in practice as a long range.. Has anyone discovered old metal with the totem? there isn't any report totem work as long range |

totem TX without problem .. why transmitter must change ?

Hello my friend . Anyone who wants to try this device. First, he must make a receiving circuit with only the receiving coil and test the device according to the operating instructions in the file attached to the first post in this topic, such as sensing the electric spark... etc. After making sure your device works very well and there are no problems or errors in assembly or parts. You go to the second step, which is manufacturing the transmission circuit and adding it to the receiver. I do not advise anyone to manufacture this device, but there are people who want to try this device (for them I am providing this information) to help them and make things easier for them and to make the appearance of the device more dynamic and acceptable. Because I think something useful can come out of this device. I will post pictures and links explaining my idea regarding the device?s narrow-band antenna. And manufacturing methods. ![]() https://youtu.be/9gjUlqH9dTQ?si=ZddyPDx97yvPaMZF I wish everyone good luck and thank you |

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. |

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 connet the test point I think with press switch and Ground

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
|
#147

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.
