Nanoscale magnetic swirls known as skyrmions can form in certain materials such as thin magnetic films. These tiny vortices pack into dense lattices that are more stable than conventional magnetic domains and can be transported and manipulated with minimal electrical power—features that hold great promise for future information storage applications

This project is a departure from that of my normal sort. It is based around an operational amplifier (op-amp)… Yup I’ve transgressed to the dark side. Actually I have nothing against integrated circuits (IC) or solid state devices and in fact use a number of solid state components in my designs. This project is for […]

(Phys.org) —Fuel cells for decentralized energy production require oxygen ion conductors: materials that can store oxygen as ions, and then transport and release it. German researchers have now found an unusual compound that is the first metallic oxygen ion conductor of its kind, as well as the first one that is active at room temperature.

ICStation team introduce you how to DIY this temperature & humidity & smoke alarm system based on ICStation Mega 2560 compatible with Arduino.The working voltage of this system is DC5V.It can measure the current temperature, humidity and smoke. It can display real-time data by the 1602 LCD and can realize the sound and light alarm […]

My brother is a Mechanical Engineer who loves his KTM Duke 200 bike. He asked me to build this circuit : http://sunbizhosting.co.uk/~spiral/blog/?p=227 for a ‘heartbeat’ lamp controller for the parking light. A Neutral Detect (ND) signal controls the lamp pulsing. When ND is HIGH, the Lamp is fully lit. When ND goes LOW, the lamp […]

This collection of circuits provides step-up voltage regulation for single cell and dual cell Alkaline, NiMH, and Li+ battery driven applications. Regulate your battery driven app with an efficient converter from Maxim. Your battery-powered application needs regulation. This collection of circuits provides step-up voltage regulation for single- and dual-cell Alkaline, NiMH, and Li+ battery-driven applications. […]

As part of my 3D printer project, one of the big electronics hurdles to overcome was a motor controller for a BLDC (BrushLess Direct Current) motor. Searching for a cheap, off the shelf controllers that would interface easily with a microcontroller turned up fruitless, so I took the opportunity to design my own circuit. It was […]

Introduction For some time I have been planning to build a number of devices that make use of stepper motors. Since I have no experience in using stepper motors I had no idea what parts, what driver and controller circuits I would need to get them running. After extensive research  on the internet I decided […]

This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful  electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used  to measue time-varying signals. Any time you have a signal that varies with time( […]

Viewers around the world preparing to watch the World Cup next month in Brazil are also to witness a special event where a paralyzed person, with the help of a robotic exoskeleton, will rise from a wheelchair, walk to the center of the field and kick a soccer ball. The mind-controlled exoskeleton is the work of an inspiring global collaboration among scientists, as part of the Walk Again Project.
