Merging classic analog signal processing with modern Arduino or ESP32 modules.
Compares changes between a reference oscillator and a search loop oscillator. Vintage designs, ultra-simple DIY projects.
The authors famously enter the "murky world" of pseudo-scientific long-range locators to debunk fraudulent claims using real science. Merging classic analog signal processing with modern Arduino

When this field encounters a conductive target, it induces small circular electrical currents called within the metal. These eddy currents then project a weak secondary magnetic field back to the receiver coil. The authors famously enter the "murky world" of
- While Carl delved into PI circuits, George Overton focused his attention on other major technologies, making their partnership highly complementary. When they discovered they were each independently writing a book on metal detectors, they realized their combined efforts would be far more powerful, with "very little overlap between the information we had compiled separately". George is an administrator on Carl's Geotech forum, known there by his avatar "Qiaozhi". He has extensively explored Beat Frequency Oscillator (BFO), Transmit-Receive (TR), and Very Low Frequency (VLF) designs, and his "Voodoo Project" is a notable example of a hybrid PI detector designed to tackle the "holy grail" of iron rejection.
Do you need help finding for an obsolete component? Are you trying to troubleshoot an existing circuit design ? - While Carl delved into PI circuits, George

With renewed excitement, the two treasure hunters began to dig once more. A few minutes later, the tip of a golden cup emerged from the earth.
