Detecting the physical conditions of a robot is always useful in robotic applications. Particularly if the robot is a rover and is designed to explore different terrains. In such applications, there are instances when the state of the robot has to be detected. It may involve detection of collision or fall, change in orientation of…

This tutorial will help you to understand the necessity of the PCB. Here, I have described the evolution of PCB in different steps. Connecting a circuit without any soldering gun or breadboard is a complex process. I tried to connect an amplifier circuit with a transistor, four resistors, and three capacitors, which you can see in the video. Connecting electronics components directly using wire, is referred as a “discrete circuit”. In the above image, it can be seen that a single lead wire 5mm LED and 1K resistor are connected to two 1.5V Duracell batteries. This is a small and simple example for discrete circuit.

With airplanes, we could traverse long distances quickly but not taking us exactly where we want to go but to the nearest airport mostly while sharing the ride with other passengers. Cars will take us to a more precise location as long as it is connected by a road, but at a much slower pace. The fusion of these two technologies will get usa hybrid which retains a portionof the positives from both sides, leading to the birth of the “Flying Car”. This technology has been promised to us by the early 21st century, since the early 1950s as seen in various articles and sci-fi movies. Although the idea has been around for a long time, it could not be converted into a tangible product since it was more complicated than that which met the eye.

Home Security Systems are a need of the modern day houses. It is possible to design a simple home security solution by using Raspberry Pi and utilizing the power of Internet of Things. The home security system designed in this project is a simple and easily installable device built using Raspberry Pi 3, Web Cam and PIR Motion Sensor. The Raspberry Pi 3 Model B comes equipped with on-board Bluetooth (BLE) and Wi-Fi (BCM43438 Wireless LAN), so, it can be easily connected with a Wi-Fi Router to access a cloud service.

The idea of noninvasive current measurement is not new. Commercial devices are available which can measure current without any physical contact. However, the topic was not popular among the DIY community because of the complexity and nonexistence of the compact non-invasive sensors, which could be studied at low power. Luckily, we have small and reliable…
