Although the most well-known use of microphones is for music and audio recordings, they’re also used in many electronics applications such as smartphones and tablets, IoT devices (such as the Amazon Alexa), teleconferencing systems, video cameras, bluetooth headsets, and security and surveillance devices. As transducers, microphones convert sound waves into electrical signals. Since sound is a…

Name: Rehman Merali Company: teaBOT Role: CEO Location: Toronto, Canada Hi Rehman, you’re a EE who started a company. Tell us about TeaBot, and why you created it?  Rehman: Technically my degree was in Mechatronics engineering, not pure EE. So that means I know enough to put ICs together, but not necessarily develop complicated RF circuit, for example. My co-founder,…

DC/DC converters are devices that convert a DC source from one voltage level to another. They’re a common element of everything from satellites, hybrid energy systems, portable electronic devices, and many more applications because they provide stable operation, high efficiency, greater reliability and also, different voltage and current levels for the same PCB design. There are many…

Sensing and controlling the intensity of heat present in a substance or object is a fundamental function of nearly every electronic application. A temperature sensor is a device used to measure the amount of heat energy generated by an object or system. These devices are usually implemented as RTDs (resistance temperature detectors), thermocouples or thermistors. When selecting a…

Whether you’re building a wearable device, or an industrial system, chances are you’ll be integrating an accelerometer. Accelerometers are electromechanical devices that measure acceleration across one, or multiple, axes. Some common uses are to detect position, velocity, vibration, and to determine orientation (for example, to orient the display in your smartphone or tablet).  The most important factors to consider when…

When selecting a Bluetooth solution for your designs, you might compare a processor and a module and think “well the Bluetooth processor is cheaper, so let’s go with that.” But the decision isn’t always so clear cut. We had the opportunity to interview Sam De Marco, a sales engineer at Laird Technologies, to get his opinion on the…

Name Derek Smith Company Tesla Controls Role CEO Chief Dancer Location Sunny San Diego, CA   Hi Derek. Which tools do you use for circuit board design? Derek: Altium – It’s very fast and easy to generate high quality output. Also, I work on many projects with mechanical engineers and being able to output STEP…
