PROJECT: Enabling Industrial Sensors For Edge Computing Using EdgeX
For industrial prototyping and design, we often need industrial-grade sensors and devices plus industrial platforms like EdgeX. But interfacing and using those industrial-grade sensors with our known boards is very difficult and unknown to us. So here we use the industrial platform EdgeX and industrial sensor and interface them with the known Raspberry Pi

CIRCUIT IDEA: Overvoltage And Undervoltage Protection For Electrical Appliances
In some places, especially in developing countries like ours, sudden ups and downs in the mains voltage are quite common. This sometimes causes a serious failure of electrical appliances like television sets, air-conditioners, and refrigerators, which are not designed to tolerate lower or higher voltages beyond a small limit

PROJECT: Automatic Water Tank Filling System
In India, many houses have two sources of water to fill the rooftop water tank. These are underground water storage tanks and municipal water supply. Based on the availability, the rooftop tank is filled either with the municipal water or with the underground tank water with the help of an electric water pump

PROJECT: Automatic Camera Based Boom Barrier Better Than The IR Based
This is a common sight at big buildings, such as shopping malls and 5-star hotels, where the entrance for staff and regular vendors has a boom barrier. The staff cars and other regular vehicles have to slow down and wait near an infra-red (IR) scanner, which reads the faint radiation of an IR tag pasted on the vehicle’s windshield. The boom barrier opens if the tag is found in its database. The process is quite efficient and works unhindered

PROJECT: Your Own Supercomputer With Super Cool Tech
There are areas where we need small computing machines that can work collectively like a supercomputer. Let us see here how it can be done. Most supercomputers have interconnected CPUs with a master node CPU that divides a large computing task into smaller tasks. These smaller tasks are assigned to the interconnected CPUs, which work together to finish the task in much lesser time
