Most shunt resistors have values below one ohm. Such low values of resistances cannot be measured reliably due to range and resolution limitation of the measurement devices. These are usually measured using resistance bridges that require a special setup. Presented...
Microrobots with live audio and video streaming capabilities can help in tracking human beings during earthquakes and also perform underground surveys. These micro-robots can inspect very minute hole areas that are not accessible to humans. Hence these microbots are...
Phones are getting smarter and more complex with many functions that most of us find difficult to use. The modern smartphone uses either a backlight display or an OLED display that can harm our eyes on prolonged use. You may...
This project aims to develop a wearable safety and alarming device that can be operated easily, especially by children and senior citizens when in distress. It may come handy as the world is constantly witnessing increase in the number...
The basic setup needed to receive the weather satellites was covered in ‘Set Up Your Own Weather Satellite Receiving Station’ article published in January issue. The antenna setup, the receivers, and decoding software were discussed in detail in that...
It is an IoT based project through which you can control four home appliances using Apple HomeKit, Hey Siri app, and ESP8266 Wi-Fi module. The author’s prototype is shown in Fig. 1. A few months ago we were thinking of...
This weather station provides such information as temperature and humidity at a place on a colourful touch-screen display. It can also control the temperature through the touch-screen user interface when it exceeds the set threshold level. The project can...
A Mini Fridge that can work with any power bank and without using harmful CFC gases. Ever heard of a 5V portable freezer? Yes, you heard it right. In this DIY we design a 5V portable freezer that is easy...
Embedded system project that generally involves a microcontroller unit (MCU) user interface (UI) is a common and inevitable requirement. The simple form of arriving this option of UI is with the help of a monochrome LCD, which serves as...
As smart devices are increasing day by day, there is need to add smartness to the old, rugged iron box. An iron box contains a simple resistive heater and thermostat to control iron’s temperature according to the fabric. Sometimes...
