The submit addresses a basic ESR meter circuit that are available for recognizing bad capacitors in an electronic circuit without getting rid of them practically from the circuit board. ESR […]
Accurate Analogue Frequency Meter Circuit
To measure frequency one does not immediately have to ‘go digital’. The analogue approach will invariably prove simpler and cheaper, in particular when the analogue readout (the multimeter) is already […]
Simple LED Voltmeter Circuit
This simple LED voltmeter circuit, although simple, is capable of accurate voltage measurement. The input is applied to the high impedance input of IC1 via the attenuator comprising of R1 […]
Recording Level Meter Circuit
This simple recording level meter circuit can be used for displaying the recording level of an audio system. The circuit shows a two—stage voltage amplifier driving a recording level meter. […]
Simple Transistor Tester Circuit
Simple transistor tester circuit is quite easy and low cost circuit, is just not built to calculate any transistor efficiency figures, however is designed to get fast testing to signify […]
Measure AC Millivolts using this Circuit
In this piece, we examine a millivolt meter circuit built around an operational amplifier that is intended to precisely measure AC millivolts. Let’s examine the specifics through the explanation that […]
