TIDesigns. A Robust Glass-Breakage Detector Reference Design This reference design describes a simple as well as a robust glass breakage detector designs using the and was developed to operate at low power, allowing long battery life. The simple design algorithm is based on the spectral analysis of a typical glass breakage signal by analyzing signal characteristics such as peak content, number of zero crossings, and frequency composition. A glass breakage alert is indicated by an onboard buzzer and an LED. The robust glass-breakage detector includes an extra thud detection stage before actual glass-breakage detection to avoid false triggering of the glass-reakage detector for sound events with signal spectrum similar to a glass-break sound CC1120EM 169 MHz Reference Design This RF Layout Reference Design demonstrates good decoupling and layout techniques for a low power RF device operating in the169 MHz frequency band.

From PESWiki Shortcut URL: See also News:Best Exotic Free Energy Technologiesand Tracking the Position of the Top 5and Directory:Best Exotic Clean Energy Technologies This page is devoted to featuring the top five exotic technologies that we know of that are closest to market. Here at PESWiki we cover the entire spectrum of clean energy technologies, from conventional methods such as solar, wind, geothermal, tide, wave, river on the one hand; to very unconventional or "exotic" technologies such as cold fusion, magnet motors, overunity electromagnetic motors, gravity motors, and vortex technologies on the other. There are many ways to harness the wheelwork of nature -- energy sources that the environment provides free for the taking -- that are not only clean but inexhaustible and ubiquitous.
Conventional renewable energy (there are 25 genres) has made great strides but has limitations. Runners Up Spreadsheet Best Exotic Clean Energy Technologies In the News.

When it’s time for spring cleaning, you think of opening all the windows, letting the fresh breezes replace the stale air in the rooms while you sweep and mop and dust the surfaces ignored all through the winter. But there are more shadowy areas in your home that need attention. Spending just a few minutes on these five often overlooked spots will transform your space into a cleaner, more liveable environment, perfect for spring and summer fun and relaxation. The Refrigerator Who knows what’s living in those jelly jars at the very back of your refrigerator shelves? Take your time, going from section of section, pulling out-of-date foods, making sure to rinse and recycle what containers you can.
Food keeps longer in the freezer, but it can still pass a useable date. The exterior of the refrigerator needs your attention, too. Your Beds and Pillows Sometimes laundering your sheets and blankets isn’t enough. The Computer The Trash Can Your Vacuum Now your spring cleaning is really complete. Origami. Science Toys. 39 Tools To Turn Your Students Into Makers From edshelf. By edshelf: A discovery engine of websites, mobile apps, desktop programs, and electronic products for teaching and learning. The Maker Movement is one of creativity and invention. Of Do-It-Yourself ingenuity. Of making things with your own hands. Building something from scratch can shift a lesson from a lecture into an experience. Students can play, diverge, tinker, make mistakes, help each other, and express themselves with the appropriate guidance of a teacher/facilitator.
The end result can be anywhere from an honest try to a creative wonder. Whatever the case, consider adding the following tools to your experiential learning toolkit. What tools do you use to help your students become makers? 39 Tools To Turn Your Students Into Makers From edshelf Image attribution flickr user nnova; 39 Tools To Turn Your Students Into Makers From edshelf.
