The ESP8266 had been in the tech scene for over four years now and has seen various competitors like the RTL8710 or, more recently, the RDA5981. But none of them has really been able to knock off the ESP8266 from its throne. The ESP8266 is seen by most as being “good enough.” So the need […]

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed a process that makes the production of a two-millimeter flat camera possible. Similar to the eyes of insects, its lens is partitioned into 135 tiny facets. The researchers have named their mini-camera concept facetVISION, following nature’s model. This mini-camera has a thickness

A new study about “Reduction of overheating of 2D materials” published in the Journal of Advanced Materials. The work put behind the study is credited to the researchers at the University of Illinois at Chicago College of Engineering. By joining together two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases, they formed an ultrathin layer

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple plant monitor. In this project I’ll introduce a new type of analog sensor that detects moisture levels. You’ll set up a light and sound alarm system (an

Vacuum fluorescent displays (VFDs) are one of those beautiful pieces of bygone technology that you just don’t see much of anymore. At one time they were a mainstay of consumer electronics, but today they’ve largely been replaced with cheaper and more energy efficient displays such as LEDs and LCDs. While they might be objectively better
