SUPERBLY SYNCHRONIZED SERVOS SWAYING SOFTLY

LEDs and blinky projects are great, and will likely never fade from our favor. But would you look at this sweeping beauty? This mesmerizing display is made from 36 micro servos with partial Popsicle sticks pasted on the arms. After seeing a huge display with 450 servos at an art museum, [Doug Domke] was inspired to make a scaled-down version. What [Doug] didn’t scale down is the delightful visuals ...

Researchers Develop Long Range Backscatter Sensors That Consume Almost No Power

Researchers at the University of Washington developed a new backscatter sensors that can operate over long ranges with very little power. The researchers demonstrated for the first time that the device runs on almost zero power and can transmit data across distances of up to 2.8 kilometers. Backscatter communication works by emitting a radio signal and then monitoring the reflections of that signal from sen ...

Researchers Developed VO2 Based MEMS Mirror Actuator That Requires Very Low Power

A joint research by the US Air Force Research Laboratory Sensors Directorate and Michigan State University have developed micro-electromechanical systems (MEMS) actuator based on smart materials, specifically vanadium dioxide (VO2). In the room temperature, Vanadium dioxide exhibits the Mott transition. It is a not-well-understood phenomenon known to occur in transition metal chalcogenides and transition me ...

Local company builds new bug-like robots to teach programming to schools

We often write about the growing trend of tech companies to make robots for the purposes of teaching the youth how to code. Today we’re doing that again, but this time telling the story of a local tech start-up doing this rather than some big international company. Because South Africans should also be learning about robotics, so why not have a local company that can help us get up to speed with where the w ...

Evaluate the Swiss precision for free!

Top-class calibrated humidity and temperature sensors Sensirion already gained many fans. Mainly thanks to a fact, that they´re not only “sensors” but a ready-made solution with a pre-amplifier, ADC and other circuits, which directly provide a final value in a digital form. That´s why it´s not necessary to solve input portion (noise, shielding, power supply, length of wires,…). Moreover, their long-term sta ...

Arduino’s new Nano board family is more powerful and affordable

Arduino's Nano line will soon welcome four new products. They're all small boards like the classic one, making Nano a family of small boards meant for compact projects. All the new boards boast low energy consumption and processors more powerful than what the classic has. Even better, they're all pretty affordable: the most basic entry called Nano Every, which you can use for "everyday" projects and can rep ...
