I got my BG7TBL RF noise source to make some RF measurements. To make those measurements, I needed some instructions how to make them. I first started with filter measurements because I could make them with the devices I have. Two good tutorials for doing measurement are Measuring Filters and VSWR With RTL-SDR and RTL-SDR →
http://www.osa.org/en-us/about_osa/newsroom/news_releases/2017/high-dimensional_quantum_encryption_performed_in_r/ For the first time, researchers have sent a quantum-secured message containing more than one bit of information per photon through the air above a city. The demonstration showed that it could one day be practical to use high-capacity, free-space quantum communication to create a highly secure link between ground-based networks and satellites, a requirement →
http://www.sciencealert.com/researchers-have-conducted-the-first-thorium-salt-experiments-in-over-40-years#.WaUkb5ppSUB.facebook Netherlands-based nuclear power provider, NRG, are taking a gamble. They’re conducting experiments that could see a shift from uranium-based nuclear power to thorium. There has been the historical battle between using uranium or thorium as a nuclear fuel. Uranium provided a potential source of weapons-grade plutonium. A significant advantage of using thorium over uranium is it doesn’t →

Most pop music is pretty much produced using computers. Is ‘Algorithm Idol’ poised to take its place in the pop music mill? Pop music automation is a field of study among musicians and computer scientists with a goal of producing successful pop music algorithmically. It is often based on the premise that pop music is →
https://qz.com/1055287/an-error-made-in-1925-led-to-a-crisis-in-modern-science-now-researchers-are-joining-to-fix-it/?utm_source=parVG In 1925, Fisher published Statistical Methods for Research Workers, whete he explained the concept of statistical significance. Somewhat arbitrarily, Fisher chose to define statistical significance as a difference that had less than a .05 probability of occurring by random chance (in technical terms, this is called a p-value). Fast forward more than a century later, →

I have played with software defined radio using cheap DVB-T stick for some time. Receiving radio transmissions is interesting, but it works also for other applications. By reading RTL-SDR Tutorial: Measuring filter characteristics and antenna VSWR with an RTL-SDR and noise source article I understood that I could use my RTL-SDR stick for many RF →
https://futurism.com/people-are-using-old-laptop-batteries-to-build-their-own-versions-of-teslas-powerwall/ Tesla’s Powerwall was intended to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. But with a $5,500 price tag, they haven’t been affordable for many consumers. Some who had been interested in the tech, however, decided to try to make their own: constructed their own powerwalls by utilizing →
