Meet Martti, the Finnish Robocar That Uses 5G – IEEE Spectrum

https://spectrum.ieee.org/tech-talk/telecom/wireless/full-capabilities-of-5g-networks-in-autonomous-vehicles-explored How will 5G work with self-driving cars? A new 5G-enabled robot car in Finland offers some clues. VTT Technical Research Centre of Finland and mobile giant Nokia have joined forces to determine how 5G networks can transmit information to and from vehicles while on the road. They are testing the capabilities of 5G network

Friday Fun: LEGO built a life size, drivable Bugatti from over a million Technic pieces

https://techcrunch.com/2018/08/30/lego-built-a-life-size-drivable-bugatti-from-over-a-million-technic-pieces/ Unbelievable PR stunt: In what just might be the wildest thing anyone has ever built with Lego, the company behind the bricks has built a full-size, drivable model of the Bugatti Chiron supercar. Seriously. https://www.lego.com/en-us/themes/technic/bugatti-chiron/build-for-real With LEGO® Technic we like to state that you build for real. And to prove this is more than

A technical performance-based view of opto-isolators and digital isolators | EDN

https://www.edn.com/design/analog/4461000/A-technical-performance-based-view-of-opto-isolators-and-digital-isolators Galvanic isolators are devices that couple an electrical data or control signal across an insulation barrier without any flow of current through it, thereby enabling signals to be transferred while blocking noise. The insulation barrier also safeguards equipment and human operators from high voltages. The earliest isolators were optically coupled devices, also called opto-isolators

Managing energy demand spikes

Managing energy demand spikes with seasonal forecasts of heatwaves and cold spells https://horizon-magazine.eu/article/managing-energy-demand-spikes-seasonal-forecasts-heatwaves-and-cold-spells_en.html The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say. Researchers already have the ability to
