1 1. 2. You should read what the author wrote about it. It's difficult to reverse engineer out details like housings from a schematic. Normally, I'd guess that L1 L 1 and C4 C 4 are in your metal detector 'coil and housing' that you use to sweep the area. However, I'm not at all feeling good about either the left side driver circuit or the ...

The Pi Metal Detector Circuit is an excellent option for projects where metal detection is necessary. It is user-friendly, cost-effective, and can be used for various applications such as search and rescue operations, security systems, and industrial applications. Furthermore, the Pi Metal Detector Circuit can also be used in …

As you can see in the video, the results are surprisingly good. Without the presence of a metal, device is perfectly stable. The range is relatively large and for example, a metal cover with a diameter of 15 cm is detected at a distance of more than 30 cm. Larger metal objects are detected at distances greater than 40-50cm.

Surf pi metal detector. DESCRIPTION. Pulse Induction Metal Detector Surf PI classic version. (Note- It is not the longboard version but i have corrected the silkscreen of resistors so you can follow the build instructions of a longboard one without any issues).

Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.
