The introduction of 3D-printed prosthetics in healthcare sector has transformed the lives of many people. It has the potential to even save lives, with applications ranging from 3D-printed hearts to prosthetic limbs. 3D printers, along with some basic tools,...
The introduction of 5G New Radio or 5GNR has helped in improving wireless communication and offering better mobile services. With 5G communication, deployment of smart antennas has become crucial for the optimisation of coverage, capacity, and mobility support for...
Artificial intelligence (AI) has been playing an important role in every field, including the education sector. AI-based platforms have helped students and teachers in getting a better learning experience. Most students find these quite interesting, exciting, and engaging. This...
At least three companies are expected to introduce their quantum computers in 2020, while some more may be working secretly on them. In India, the Tata Institute of Fundamental Research has undertaken to lead this national mission. Fundamentally, quantum computing...
This project is based on an infrared (IR) sensor, which detects the presence of hands and consequently activates the motor pump to dispense alcohol-based sanitiser. The circuit is economical, reliable, and can be easily constructed, as explained below. Circuit and...
The introduction of eSIM (embedded SIM) has helped in the growth and transformation of the Internet of Things (IoT) based devices to a large extent by allowing manufacturers to build a new range of products for global deployment. eSIMs...
Most microphones’ output signals are weak and cannot be directly connected to some other circuits. Also, some microphones require DC power supply or high impedance inputs. Here is a dual (stereo) preamplifier for microphones that can be used with...
With the advances in science and technology, there has been a phenomenal growth in the use of electronic devices in the medical field. At present, various electrical devices are being engineered that could help patients recover from illness by...
The circuit presented here is a simple device to enhance the utilisation of hot water from a solar water heater system. Normally, during day time, you get hot water continuously from the solar water heater due to the presence...
Voltage sources in a circuit may have fluctuations resulting in not providing fixed voltage outputs. A voltage regulator IC maintains the output voltage at a constant value. 7805 Voltage Regulator, a member of 78xx series of fixed linear voltage...
