In this article I will elucidate many assorted circuit ideas built using NAND gates from ICs such as IC 7400, IC 7413, IC 4011, and IC 4093 etc. IC 7400, IC 7413 Specifications The I.C.s 7400 and the 7413 are 14 -pin DIL ICs, or “14 pin Dual In Line Integrated Circuits”, where pin 14 […]
Newly Updated Circuit Projects:
Fiber Optic Circuit – Transmitter and Receiver
Electronic signals have been quite successfully sent for decades through standard “hard -wire” connections, or by using radio links of different kinds which had many disadvantages. On the other hand fiber optic links, whether used for audio or video links over long ranges, or to handle small distances, have been offering some distinct advantages compared […]
50 Watt Sine Wave UPS Circuit
The UPS detailed in this article can provide a power output of 50 watts consistently, at 110 volts with a frequency of 60 Hz. The output is fundamentally a sine wave that behaves exactly like standard mains home AC power for the load. An integrated power supply works like a battery charger. Even though the […]
Different Types of UPS systems – Explained
In this post I am going to explain different types of uninterruptible power supply (UPS) that are available in the market and how they are classified according to the consumer’s requirement. We will also explore the different types of UPS’s block diagram to understand their technical difference between them. UPS systems are a type of […]
Ultrasonic Burglar Alarm Circuit
An ultrasonic burglar alarm circuit is an electronic device which transmits ultrasonic waves to detect the movement of an intruding person. The ultrasonic waves hit the intruder and the reflected waves are picked up by the circuit. This reflected wave is used to activate a loud alarm which alerts the owner about the presence of […]
DC Power Controller Circuit
In this post I have explained a DC power controller circuit which can be used for controlling the power of motors and lamps with maximum efficiency. By Sangeeta Naik How MOSFETs conduct to Handle Power Efficiently A minimum amount of power is lost whenever a power transistor (BJT or MOSFET) is in the turned off […]
