Hacks of Electronics
If you are looking for a first-class 40-watt music stereo amplifier, then look no further. High output efficiency, negligible hum, low harmonic distortion, clarity of the output sound, compact (modular) size, and low cost are some of the key features of this fully solid-state integrated Hi-Fi stereo amplifier which is capable of delivering an output […]
The LM380 is an audio power amplifier for consumer application. Its internal gain is fixed to 14dB in order to keep the system cost minimum. A unique input stage allows inputs to be referenced with the ground. The output gets automatically self-centered to one half the supply voltage. The output amplifier is short circuit proof […]
In this article, we will discuss how we can make a triangle wave generator using opamp. So, let’s start discussing how to make a triangle wave generator. A triangle wave is consisting of a constantly rising and falling slope. An opamp integrator gives a triangle wave. If you are an electronics student then you might […]
Have you thought about who turns on and off those street lights on the road? Turning on and off those street lights may be a boring task. We can make this process automatic by a simple automatic street light circuit. Also, you can automate your home lighting, lights in the garden, and other outside places […]
In this project, we will use the MQ2 Gas sensor circuit to detect Methane, Butane, LPG, Smoke which is released into the environment at the time of the gas leak. MQ2 Gas sensor circuit diagram is as shown in the figure. MQ2 gas sensor can sense butane, LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon […]
This Automatic battery charger circuit cuts-off power supply when the battery gets fully charged. This circuit can charge any battery like Li-Po, Lead Acid, or Ni-Cd if you set it properly. Everyone needs a Battery Charger with a Battery. It charges the Lead Acid Battery up to 50Ah. You can set the battery cutoff threshold by setting […]
