High-level programming languages do a great job of making a programmer’s job easier, but these languages often leave a lot of efficiency on the table as a compromise. While a common thought is to move into a lower-level language like assembly to improve on a program’s speed or memory use, there’s often a lot that […]

Home automation refers to the ability of your home to make its own decisions depending on environment conditions and give you the option to control it from a remote location. In one of our previous tutorial on the ESP8266 WiFi Module, we examined how NodeMCU or any of the other ESP8266 based boards can be used to build a web server

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that provide a magnet-or-not digital output are only part of the story, and linear Hall effect devices provide a handy way to

Many of will have marveled at the feats of reverse engineering achieved by decapping integrated circuits and decoding their secrets by examining the raw silicon die. Few of us will have a go for ourselves, but that doesn’t stop the process being a fascinating one. Fortunately [Ryan Cornateanu] is on hand with a step-by-step description of

While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to detect objects, the same principle has been used with other propagating waves, most often sound waves. While a well-known use of this is sonar, ultrasonic sensors

AAEON launched their UP board family back in 2015 with the original board featuring an Atom X5 Cherry Trail processor. Since then they’ve launched more models all based on processors with 10W or lower TDP (Thermal Design Power) such as UP Squared Apollo Lake development board. Now, they have introduced an Intel Core-U series Whiskey Lake processor (15W TDP)
