With about 40 percent of the world’s food produced using irrigation, it’s a major factor in food security. Amid concerns about water availability for agriculture, making the most of every drop is increasingly critical. UNL computer engineer Mehmet Can Vuran developed technology to help farmers boost yields and conserve water, with support from a National
When working in extreme temperatures it is important to monitor your body temperature. In freezing weather, your fingers and toes get numb and you can develop frostbite without even noticing it. Likewise, if your core body temperature drops too low, you can start to start to suffer the effects of hypothermia before you are aware

New version of a favorite RFID module ID12LA will enable you to implement RFID into your device even more easily thanks to a wide range of supply voltage. Literally “globally known” with an integrated antenna – ID12 and its familiar like for example ID2 or ID20 have earned a big popularity thanks to a flawless
RFID module ID12LA will also abide a lower voltage …ccc Read More »
A long, long time ago there was a great Design Idea for a simple gadget to find a bad bulb in a series-connected string of Christmas lights: This is really simple and works great, but it exposes the user to potentially lethal line voltages. The PROBE in the figure above is inserted into the light

ORLANDO, Fla. — CES 2015 debuts the future of smartphones coming from all places, Moscow, where mother-company Yota Devices is partially owned by the Russian government. Shown in the E-Ink booth at CES, the YotaPhone, as its called, is not yet available in the U.S. and its a good thing, since that gives Apple, Samsung
Scientists at the Nanyang Technological University (NTU) in Singapore have developed a smart window that is able to tint itself blue, partially blocking incoming light, without the need for an external power source. The device also functions as a small transparent battery that recharges on its own simply by interacting with the oxygen in its

Tog can remotely control Bluetooth enabled devices such as smart phones, laptops, lights, locks and much more. When you press Tog it will wake up and communicate with your phone to execute pre-assigned actions. Tog ships with
I came across a stash of iButton T-sense 1-wire sensors.. so I grabbed a couple and decided to check out 1-wire. Maxim makes a 1-wire device called the DS18B20. It’s a 9-12 bit temperature sensor with the possibility of being powered by parasitic power from the data line. This cuts the signal path down to a
