Introduction Frequency domain analysis is very important to know more about any system/ circuit or transfer function that we deal with. And the first thought comes to our mind about frequency domain analysis is “Bode plot“. Bode plot is a combination plot of magnitude and phase difference of output vs. input of a cosine wave […]

Nowadays, Wi-Fi is a word we hear often, and it is a technology that we use all the time. There are around 279 million Wi-Fi hotspots in the world, and in 2021 that number is expected to increase to 542 million hotspots. The wireless nature of this technology allows users to access a network from […]

FriendlyElec recently released a pretty exciting hacker board which is super cheap, considering the features of the board and the price it is being sold for. The Single Board Computer (SBC) is based on Rockchip RK3399; a low power, high-performance processor. The board which is called Nano PC – T4 can be regarded as the […]

In this post we will discuss Efficient Energy Management System with Smart Grid. Smart Energy Management is the system, which uses communication and control centre for simplifying and upgrading the power system. In this paper, different types of energy management systems are discussed and also analyzed various methodologies adopted for implementation of smart grid. Introduction […]

After making your PCB prototype the significant next step is placing your components on the printed circuit board. Depending on the sophistication of the prototype being developed, the number of parts to be used, and the parts layout; one might want to solder the components to the PCB board manually. Soldering components to a PCB […]

In this post we will learn IOT based temperature data logger using esp8266 and pic microcontroller: The project ESP8266 Temperature Logger using PIC16F887 is build up using PIC16F887 microcontroller (MCU), ESP8266 WiFi module and a ThingSpeak API. Previously, we posted Arduino and ESP8266 based webserver and this project is somehow similar. IOT Based Temperature data logger […]

Earlier this month, Google released Android Things 1.0 and announced many consumer products that will ship in the coming months based on the stripped-down, IoT-oriented Android variant. Google uncovered four ARM-based production boards for Android Things 1.0: Innocomm’s i.MX8M based on WB10-AT, Intrinsyc’s Open-Q 212A and Open-Q 624A, based on the Snapdragon 212 and 634, […]

In this project, we are going to develop a PIR sensor and GSM based home security system. This project is developed using 8051 microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. Let us know how to develop this system, step by step. Required Components […]

Dire situations require unpleasant solutions, an excellent example of this statement is spying and we have seen what the NSA has done in this regard. It goes against proper ethical character, however, it might be needed in certain circumstances. Usually, the first thing a person who wants to spy would do would be to check […]
