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 […]

GPS modules from company Quectel have excellent features and enable a relatively quick development of applications also thanks to ready-made development kits. GPS receivers are still more often used in various segments, what is also reflected in our offer of top-featured GPS modules from company Quectel. Naturally, it is ideal, when there´s also available a […]

In our quest to reuse and restore everyday household items, such as CDs, there have been a number of reuse ideas we have offered our readers, such as how to reuse CDs to make wind chimes, coasters, Christmas tree decorations, room separators (by suspending a string of them from your walls), or even a funky […]

Microchip announces two new 8-bit PIC microcontrollers (MCUs), the PIC16F527 and PIC16F570, which combine a PIC MCU with a dual Op Amp module, an 8-bit ADC and two comparators. The new MCUs add several features to support ease of use and system robustness. The all-new hardware interrupt capability gives designers the freedom to implement more […]

If you have ever played one of those coin-operated pool tables in a place like a restaurant or an arcade, then you know that the obvious question is, “how the heck does this thing return the cue ball to me???” If you look inside the table, there is a system of chutes that connect to […]

A team of researchers from the National University of Singapore’s (NUS) Department of Electrical & Computer Engineering has developed a robot fish that mimics the movements of a carp. This robot which is essentially an autonomous underwater vehicle (AUV) is ready for applications, as it can be programmed to perform specific functions, for example, for underwater archaeology such as exploring nooks and corners of wreckage—or sunken city which are difficult for divers or traditional AUVs to access.

This article looks at the integration of sensors into 4 to 20 mA control loops and field bus implementations in industrial automation applications. Adding intelligence to the sensor allows more control and options for closed or open control loops with tighter latencies, and the article looks at the different approaches to implementing a smart sensor […]

The technology behind the LCD projector is nearly three decades old in 2012, but it remains one of the top digital projection technologies, alongside Digital Light Processing (DLP) projectors. Inventor Gene Dolgoff developed the first LCD projector in 1984, and both Epson and Sony continue to employ the technology in 21st century projectors. The old […]
