In this post we try to investigate how to design a SG3525 full bridge inverter circuit by applying an external bootstrap circuit in the design. The idea was requested by Mr. Mr. Abdul, and many other avid readers of this website. Audio/Video Representation Why Full-Bridge Inverter Circuit is not Easy Whenever we think of a […]

Automatic Battery Full Cut-Off Latching Circuit with Trickle Charging
In this post I will explain one useful SCR relay battery overcharge cut off circuit, which also has automatic latching and small trickle charging feature, so now when battery becomes fully charged then charger disconnects automatically, but still a tiny current keeps going into battery slowly. Main Features Main interesting thing here is the SCR […]
Cup Full Indicator Circuit for the Visually Challenged
This circuit basically is a fluid level alarm indicator intended for alerting visually impaired individuals regarding the liquid level in a container such as cup, glass or bowl. The unit can be simply hooked up across the rim of any container with the probes such that it detects the full level liquid in it while […]
Mp3 Player Using DF Player – Full Design Details
In this post I will show how to construct an Mp3 player using arduino and DFPlayer. The proposed article has two Mp3 player designs, one with push button control and another one with IR remote control. We will also take a look at DFPlayer (Mp3 player module) and its specifications. We all love music, we […]
How Electret Microphones Work – Full Tutorial and Diagram
In this post I have explained how electret microphone devices work, through appropriate diagrams and formulas. What’s a Microphone A microphone is a device designed for transforming weak sound vibrations into tiny electrical pulses, which can be then amplified through a power amplifier over a loudspeaker for achieving a louder reproduction of the sound. The […]
Diode Rectification: Half-Wave, Full-Wave, PIV
In electronics, rectification is a process in which a rectifier diode converts an alternating full cycle AC input signal into a half cycle DC output signal. A single diode produces half wave rectification, and a network of 4 diodes produces a full wave rectification In this post we will analyze both half wave and full […]
