Right here a easiest yet quite precise inductance meter is introduced, which is often developed within couple of minutes. Moreover, the circuit may be powered-up with a single 1.5V cell. […]
How to Build a ESR Meter Circuit
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 […]
