Creating a Local Network to share personnel and confidential data’s has become almost impossible for a common man in our modern world. This is mainly because all common chat methods like Whatsapp, Facebook, Hangout and almost everything involves an internet connection. What if, we could share data without the medium of Internet? How cool it […]

I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to the Micro Amps“). I have that transceiver

Amazon’s Dash Button, which I previously mentioned back in late May 2015, is the ultimate in consumer convenience (or, if you prefer, consumerism gone crazy). Simply press a button on the inconspicuous adhesive-backed device (perfect for attaching to your washer and dryer, refrigerator, counter, or cabinet), and your Amazon account is charged for the purchase

California, where I once lived, is in the midst of a severe drought. Thankfully, I now reside in North Carolina, a much wetter state. But even here there have been years when water was in short supply and people were asked to conserve. Most folks are happy to comply with such requests. But that’s not

Automation is defined as using various control systems to operate equipment such that there is minimal human intervention. Closed control loops (feedback systems) regulate how other systems or devices behave by taking into consideration their output and making corrections based on feedback. An example of this feedback system is Progressive Automation Linear Actuators. In this
