In this we post we discuss an accurate continuity tester circuit whose measuring capacity could be adjusted depending on the resistance range of the load under test. The range of […]
LED Sound Level Indicator Circuit
The proposed LED sound level meter will detect the sound hitting the MIC, and indicate its volume level through an array of LED, connected as a bar graph. Circuit Description […]
Diode Matching Circuit (Pairing Circuit)
In one of our projects we required several matched silicon diodes for accomplishing a perfectly balanced modulation design. We could easily construct it through a 9 V battery for the […]
Simple Capacitor Tester Circuit
This simple capacitor tester can be used to identify the values of unknown capacitors. This bridge design was actually built to come across values for odd, unmarked or unknown capacitors. […]
FET Voltmeter Circuit
Eventhough a common multimeter is appropriate for almost all DC voltage measurement it may at times demonstrate to be insufficient. This can be the situation when designing measurements on higher […]
Audio Frequency Meter Circuit
ON SEVERAL events it is really beneficial to manage to establish the frequency of an audio signal. Usually, the consistency and cost of a commercial frequency meter is not really […]
