In this post we discuss an universal 6V, 12V, 24V automatic battery charger circuit specifically designed to charge automobile batteries under harsh environments, and which can be used by auto mechanics without much maintenance. The design incorporates a thyrister (SCR) for executing the automatic cut offs. As displayed in the full circuit diagram […]
Programmable electronic Door Bell Circuit
This programmable electronic musical door bell circuit is really simple since the integrated circuit really does all the things! It should be stated that we now have created some substantial modifications to the application plan. As shown in the below diagram the power supply is extracted from the 230 V mains: the TF1 secondary (2 […]
Metal Detector Circuit using Single Transistor – Tutorial
The post explains a simple one transistor metal detector circuit which is very sensitive and and can detect any metal from a significant distance. We are going to begin the topic assuming situations have settled following a few cycles and the voltage within the base of the transistor is steady (fixed by the “retaining” or […]
36 Watt BTL Power Amplifier Circuit using IC TDA1562Q
This 36 watt power amplifier circuit is structured over a class of Philips H-Audio Amplifier IC and may provide 36W RMS or 70W audio power, all coming from approximately a 14V power supply. This innovative Powerful Midget Amplifier can definitely throw a punch of about 36 W constant RMS right into a 4 ohm loudspeaker […]
Adjustable Power Supply 3 to 30V 3A Circuit
The explained adjustable power supply 3-30V 3A is a stabilized (regulated DC Power) power supply intended for testing just about all circuits in general, according to a stabilized DC voltage of 30 volts This particular power supply was made as an auxiliary or as a long term power supply for many common circuits structured on […]
Simple 12 watt Amplifier Circuit using TDA1020 IC
In this post we study a very simple yet powerful 12 watt amplifier circuit using a single chip TDA1020 and few other handful of passive components. The TDA1020 is designed in the form of a monolithic integrated 12 W audio amplifier in a 9-lead single in-line (SIL) plastic package. Typically the unit is principally created […]
