Introduction Now and again there’s a need to expand the I/O capabilities of your chosen micorocontroller, and instead of upgrading you can often use external parts to help solve the problem. One example of this is the 74HC4067 16-channel analog multiplexer demultiplexer. That’s a mouthful – however in simple form it’s an IC that can direct […]

Flooding is the most frequent and widespread weather-related natural disaster, taking a huge toll in lives and property each year. NASA Earth-observing satellites and airborne missions provide vital information to emergency planners, relief organizations and weather forecasters, helping to improve flood monitoring and forecasting, as well as providing a more comprehensive understanding of one of Mother Nature’s most damaging hazards.

From time to time many of us are facing the same problem when trying to charge your smartphone or tablet from the USB port – it just not charging. Recently I have bought USB car charger to power my Samsung Galaxy Tab 10.1 on the road just to discover it doesn’t work. Even though the […]

Using ancient DNA analysis and other techniques, a research team led by conservation biologists at the University of California, Riverside has determined that bighorn sheep, so named for their massive spiral horns, became extinct on Tiburón Island, a large and mostly uninhabited island just off Sonora, Mexico, in the Gulf of California, sometime in the last millennium—specifically between the 6th and 19th centuries.

Texans, known for enjoying local beers and Dr Pepper soft drinks, now have a growing beverage industry that would appeal to James Bond, who is well-known for enjoying a good martini. Distillers are producing at least 17 Texas vodkas, researchers reported here today, and the most popular are, surprisingly, those that are a bit salty.

This weeks PAW is something that I have wanted to have for a long time but never gotten around making – until now that is 🙂 Everytime I solder a SMD LED on a pcb I have to turn on one of my multimeters and flip it over to diode-test mode and then probe the […]

While the world’s best athletes competed during last month’s winter Olympics, doctors and scientists were waging a different battle behind the scenes to make sure no one had an unfair advantage from banned performance-enhancing drugs (PEDs). Now, for the first time, researchers have unveiled a new weapon—a test for doping compounds that is a thousand times more sensitive than those used today.

An adventure of the Southern Appalachian Space Agency, by Travis Goodspeed <travis at radiantmachines.com>, as presented at Summercon 2013, inspired by the lectures of Adam Laurie and Jim Geovedi, with kind assistance from Skytee. At Black Hat DC in 2008, I watched Adam Laurie present a tool for mapping Ku-band satellite downlinks, which he has […]

Chicken fat, pork fat or beef fat –– none is the cornerstone of a healthful diet –– but animal fats, including those from alligators, could give an economical, ecofriendly boost to the biofuel industry, according to researchers who reported a new method for biofuel production here today.

This is a great process achievement by SiTime. They have managed to cure the problem of MEMS oscillators over temperature at the source—the MEMS itself. Kudos to the process engineers! SiTime Corporation has introduced the TempFlat MEMS. Until recently, all MEMS oscillators used compensation circuitry to stabilize the output frequency over temperature. This new design […]
