Transistor Subminiature Receivers Handbook for the Home Constructor

“The increasing complexity of electronic equipment has forced manufacturers to concentrate on reducing the size of their components without any reduction in performance. Miniaturization has been achieved not only by using smaller versions of standard components but also by the …

“Waste Heat” Can Be Converted Into Electricity, Research Finds

“Harnessing a phenomenon called the Rashba spin-Seebeck effect will enable commercial devices to turn waste heat from computers, cars, and solar cells into electricity Mechanical engineers at the University of California, Riverside, have reported success in using inexpensive materials to …

WHAT ENGINE IS THAT? - Step Motor Laboratory

“What motor is this? Have you ever asked yourself that question? Well, today we are going to address the electrical characteristics of an engine. Were doing this because scrap robotics often involves some frustration, and my intention, therefore, is to …

Arduino Snake on a VGA Monitor

“Well… I bought an Arduino. Initially, the investment was motivated with something that would make my daughter interested in programming. However, as it turned out, this thing was more fun to play with for me.After playing around with making …

Artificial intelligence in action

“At the MIT-IBM Watson AI Lab, researchers are training computers to recognize dynamic events. A person watching videos that show things opening — a door, a book, curtains, a blooming flower, a yawning dog — easily understands the same type of …

Blazing a Path for Buried Bits in Quantum Chips

“Microscope-guided process for creating quantum bits is widely accessible to smaller labs. NIST researchers have pioneered a process that drastically simplifies fabrication of the kind of nanoscale microchip features that may soon form the basis of a quantum computer, among …

Cheaper, less toxic and recyclable light absorbers for hydrogen production

“Mimicking photosynthesis in plants, using light to convert stable and abundant molecules like water and CO2 into a high energy fuel (hydrogen) or into chemicals of industrial interest, is a major research challenge today. However, achieving artificial photosynthesis in solution …

Diamond-Based Circuits Can Take the Heat for Advanced Applications

“When power generators like windmills and solar panels transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching new diamond semiconductor circuits to make power …

Discovery could make ultra-powerful batteries safer, more efficient

“Mechanical Engineering Professor Bingqing Wei leads team to curb formation of harmful dendrites in lithium metal batteries From smartphones to electric vehicles, many of today’s technologies run on lithium ion batteries. That means that consumers have to keep their …

ESP32 LORA: Gas Sensor, Moisture, and Temperature by SMS

“Sensors, with an ESP32 LORA, can be easily designed for safety purposes involving gas, temperature, and humidity. Today, Im going to show you precisely how to use this microcontroller module as a Sender and Receiver. Also, I’ll show you …
