Mobile Signal Vibrator Circuit
This mobile signal vibrator circuit will detect the wireless high frequency signals from your mobile phone and will activate the connected vibrator motor. This circuit can be used for many […]
AC 220V Over Current Monitor and Cut OFF Circuit
The proposed AC mains 220 V load over current cut off circuit continuously monitors the current flowing through a connected load. If this current increases beyond a certain preset level, […]
ON/OFF Relay Switch Circuit using Reflection Sensor
This 220 V ON/OFF electronic relay switch can be toggled ON/OFF simply by alternately bringing your finger close to the reflection sensor CNY70. About CNY70 CNY70 is an infrared reflecting […]
Simple Vibration Sensor Circuit
As its name suggests, this simple vibration sensor circuit using piezo transducer allows for the detection of vibrations to which its sensor is subjected. Unlike superficial pressure sensors whose resistance […]
100 Watt Power Amplifier Circuit using a Single IC TDA7294
Building a power hi-fi amplifier with MOS transistors requires the implementation of a relatively large number of components because, at the level of power stages, the connection between the bipolar […]
