Simple Metal Detector Circuit Using BC548 Transistor
In this project, we are going to build a simple metal detector circuit using a BC548 transistor. Metal detectors generally come in one of three types: very low frequency (VLF), beat-frequency oscillation (BFO), and pulse induction (PI). Metal detectors operate by transmitting an electromagnetic field from the search coil to the ground.

Bring a printed webpage and they honor the site price of $14.99. I typically go out when the sun is coming up and can say the Cen-Tech does not like moisture. Had even electrical taped the case seam and the sensitivity dial stopped working about 30 min into it. That was just from "dampness" not actually getting wet.
Simple BFO Metal Detector Schematic Diagram
This simple BFO metal detector requires only a few of components and an evening's work. The two oscillators are simple Colpitts designs using BJT transistors. The reference oscillator's frequency is approximately 370kHz, slightly tunable with the help of a silicon varactor diode. The outputs of the two oscillators are fed to a mixer made with ...
How to Use a Cen-Tech Digital Multimeter to Check the …
If your Cen-Tech digital circuit tester is a four-digit multimeter, for instance, it will determine the suitable range to show while taking a reading. If you were to measure a voltage with a multimeter, instead of seeing 0.029V, you'd see 29.34 mV. Take note of the multimeter's primary selection wheel located on its face.
