classe coil circuit | Next Electronics

Every DAC board and decoder includes a power supply component. The only missing part is the power transformer. A toroidal transformer can be utilized, featuring a power switch and fuse holder mounted on the chassis. This document presents one of...

Motionless Electromagnetic Generator (MEG) Free energy

An electromagnetic generator without moving parts consists of a permanent magnet and a magnetic core that includes first and second magnetic paths. A first input coil and a first output coil are positioned around sections of the first magnetic path,...

CENTER TAPPED TRANSFORMER AUDIO OSCILLATOR

The oscillator circuit employs a center-tapped transistor output transformer that functions as a load for the collector of Q1, provides a feedback signal to the base, and acts as the output winding to drive the speaker. Resistor R1 supplies DC...

Inductance and Capacitance Meter Adapter

This project is currently under construction and has not been validated for functionality. A signal generator, resistor, and oscilloscope were utilized to measure the value of an inductor for a battery charger project. In the search for an affordable L-C...

Magnetic Field Meter

Using a pickup coil to drive an amplifier (IC3A-B-C-D), this meter circuit can be directly calibrated in field intensity units. R3/C3 and R12/C7 establish a frequency roll-off that compensates for the pickup coil's sensitivity and set a 20 kHz cut-off...

Inductance adapter for frequency meter

The following circuit enables measurement of the inductance of the inductor labeled LX, which is the inductance to be measured. The output of the circuit is a TTL square wave whose frequency relates to the inductance being measured. The heart...
