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

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

When you press the button on a camera and hear that distinctive click, you’re hearing the sound of the camera’s shutter opening and closing in a fraction of a second. The shutter opens to let light through to the film or electronic sensor, and closes again. If you alter the length of time the shutter

Thermocouples are a great way to take accurate temperature measurements in hard to reach places or in very rugged environments. Using one can be tricky if your new to the device. This circuit has two parts the thermocouple needs to be driven by a device and then an amplifier can be used to amplify and

In any sound system, ultimate quality depends on the speakers. The best recording, encoded on the most advanced storage device and played by a top-of-the-line deck and amplifier, will sound awful if the system is hooked up to poor speakers. A system’s speaker is the component that takes the electronic signal stored on things like
