By donning a pair of white earbuds, people can drown out the outside world to a personally customized soundtrack. Wouldn’t you know it — that’s what we do when we get in the car and crank […]

Whether your energy harvesting application uses large solar panels with high voltages and currents or, more often the case, must make do with minute amounts of power derived from various other ambient energy sources, one thing is almost certain: some type of energy storage is on board, whether in the form of a small rechargeable […]

Two examples of MMORPGs: “World of Warcraft” and “Guild Wars” Regardless of whether people play because of a sense of purpose or a desire to gather huge amounts of virtual wealth, in the past few years, MMORPGs have really taken off. Although they still don’t make up the bulk of video game titles, the top-selling […]

There are many different types of accelerometers for industrial applications, ranging from the latest micro-machined capacitive devices to traditional rugged piezo electric crystals. The boom in portable devices and the advantages of knowing the position and orientation of the equipment, as well as the increased use of accelerometers in vehicle air bags, has led to […]

When Molecules Collide At its most basic level, sound is one way we perceive vibrations. When an object inside the Earth’s atmosphere vibrates, it pushes against and pulls on surrounding air molecules. In turn, they affect surrounding air molecules. It becomes a chain reaction. Imagine a bell. When it rings, its surface actually flexes inwards […]

So, why this project and why now? I generally get project ideas before looking for components. For the whistled, things were the other way around. A few months ago, when finding a new 32pins Cortex M4 , I got plenty of ideas and the whistled was one of them. As mentioned in the video, this […]

The History of PlayStation In 1988, Sony entered into an agreement with Nintendo to develop a CD-ROM attachment, known as the Super Disc, for the soon-to-be released Super Nintendo. Due to many contractual and licensing problems, the Super Disc was never released. Instead, a modified version was introduced by Sony in 1991, in a system […]

Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter for your control circuit. There are plenty of resources you can find […]

The Aithon board is a fully integrated microcontroller board with a 32-bit ARM Cortex-M4 and a powerful, easy to use software library. The Aithon board is a microcontroller board that combines the power of a 32-bit ARM Cortex-M4 with several integrated features that make robot building and experimentation fun.  We set out to create a […]
