Both items together will help your understanding of the metal detector circuits. As pointed out earlier, the sensor-head of the circuit is a 50 turns (25T top + 25T bottom) 'printed' coil tapped at first turn. The single turn (1T) feedback coil (L1) is routed to the base of Q1 via C2, and base of Q1 is biased by R1 while end of the coil ...
How to Make Your Own Detector
When you are ready to start soldering, install the parts, one at a time, to the top side of the board (Fig. 2). The wire pigtails will protrude through to the copper underside. Secure each wire with a drop of solder to the copper adjacent to the hole. Double-check polarity of capacitor installation.
Building Your Own Electronic Organ Circuit
The circuit consists of a tone generator and a vibrato unit that we can build separately. A probe is used to select the correct notes, and the note's frequency depends on the resistance in that chain. A low-frequency signal, called vibrato, can be added to the note to give it character. The oscillator is a phase-shift type, and the output is ...
