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 […]
Ceiling LED Lamp Driver Circuit
Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These lamps beautifully merge with the flat ceiling surface of our homes, offices or shops providing an aesthetic look for the lights, along with a high […]
LED Oscilloscope Circuit
The simple LED oscilloscope circuit I have explained in this article can be used for analyzing low frequency waveform through a 10 x 10 LED matrix display. Due to the involvement of only 100 LEDs in the display board, the resolution is low, and the waveform display clarity is not so impressive. Yet, this LED […]
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 […]
