The power-management IC (PMIC) supports and manages the transducer and energy-collection channel, the energy-storage element (battery, conventional capacitor or supercapacitor), and the processor/wireless link. This critical block of any energy-harvesting design implements several major functions: Captures and extracts the random, miniscule energy from the source transducer Transforms that extracted power into energy for the storage […]

Digital Picture Size The picture size is measured in pixels, so you need to pay attention to how many pixels wide and high the pictures you take are. Generally, a computer screen is 800 to 1200 pixels wide, with 800 being the most common setting. If you are e-mailing someone a picture that they are […]

Here is a really small side project that I developed while working on something else… I had to test a RC speed controller that I wanted to use to control an electric car window motor, and for the 100th time I was facing the same dilemma: find 8 batteries for my remote control, dismount the […]

The Tour Begins When Pete returned, he started the tour. He took me through the main work area — a large, dark space with desks and cubicles arranged as if they were meant to stop an oncoming invasion. Most of the desks were empty on November 3rd — Pete explained that many Bungie folks were […]

My E-Paper boards finally arrived. They look awesome. I totally nailed the cutouts for the e-paper display. They’re perfect. The ribbon connectors on the display fit nicely through the slots. They clip right into the breakout board, which is perfectly aligned over the holes for the 7-pin headerThey clip right into the breakout board, which […]

The Flexplay Twist The secret to Flexplay discs is an extra layer added to a standard DVD structure. This specialized layer includes a chemical compound that readily combines with oxygen in the atmosphere to form a new chemical compound. While the original chemical compound is transparent, the new chemical compound is opaque. When the layer […]

Do you think programming is difficult? Did you think Robotics is just for programmers? We don´t think so. Our aim is to make robotics accessible to everyone. At Minirobots we have developed mOwayduino, an open source robot, based on Arduino technology. mOwayduino robot is ready to program,  with  multiple built-in sensors, motors and more. You don´t need […]

Power Paper Products There are already several products available that Power Paper batteries can be integrated with; and with devices becoming increasingly smaller, the market for thin power sources is huge. It’s really the new devices that are yet to be developed that will make the most use of this new technology. Because Power Paper […]

Digital control optimizes the efficiency, line, and load regulation of a DC-to-DC switching voltage regulator. Engineers are able to adapt the regulator’s closed-loop response, for example, to perfectly match the demands of their product. However, digital control really comes into its own in a more complex system that comprises several regulators. The individual devices can […]

Types of Streaming Media Players Not all streaming media players are the same, and some will fit your personal needs better than others. In addition to the particular services each one offers, you’ll probably want to decide which type of streaming media player works best for you.
