The discussed audio amplifier circuits are designed around the versatile L165V amplifier IC, which is quite adaptable in various scenarios. Working Voltage Range While the minimum recommended supply voltage is 12V, the L165 amplifier circuits show satisfactory operation even below 9V, albeit with somewhat reduced performance. On the upper end, the absolute maximum supply voltage […]
Newly Updated Circuit Projects:
Making a Strong RF Discharge Circuit
In this article we study an RF discharge generation concept also called EMP generator capable of producing an intense RF electrical discharge in the air which may have the potentials of paralyzing and permanently damaging all electronic systems in the close vicinity. The idea was requested by Mr. Nidal. Technical Specifications I have seen a […]
Low Pass Filter Circuit for Subwoofer
In this post I have explained a simple low pass filter circuit which can be used in conjunction with subwoofer amplifiers for acquiring extreme cuts or bass in the frequency range 30 and 200Hz, which is adjustable. How it Works Several low pass filter circuits for subwoofer application are presented all over the net however […]
Footsteps Detector Circuit
By sensing vibrations from footfall, a Footsteps Detector Circuit is a creative and affordable approach for catching intruders. It employs a simple setup with a low-cost loudspeaker and a mute switch to pick up even the smallest steps. This simple circuit is excellent for enhancing building and garden security. We’ll go through the fundamental components […]
How to Connect LM338 IC in Parallel to Increase Output Current
The LM338 is an adjustable 3-terminal positive voltage regulator capable of providing up to 5 amperes of output current. To increase the output current capability, you can connect multiple LM338 ICs in parallel. When you connect them in parallel, each IC will share the load current, allowing you to achieve higher total current handling capacity. […]
Touch Alarm Circuit
The touch alarm circuit senses the mains hum signal from an intruder’s body and raises the alarm sound. This happens whenever an intruder touches a potential element set as the sensor, such as the door knob, or any object that needs to be protected. If the circuit is linked with the door knob, the circuit […]
