Researchers from the Chinese Academy of Sciences have developed a new type of wearable electric generator, which harvests energy from the wind as you walk. The team says it’s low cost and efficient enough to power small sensors and LEDs.Continue Readin… Continue reading Tiny wearable wind farm harvests energy from flapping plastic strips
[Dirk] shared a fascinating project of his that consists of several different parts coming together in a satisfying whole. It’s all about wanting to do target practice, indoors, using a simple red laser dot instead of any sort of projectile. While it’s possible to practice by flashing a red laser …read more

I published the following diary on isc.sans.edu: “Weaponized RTF Document Generator & Mailer in PowerShell“: Another piece of malicious PowerShell script that I found while hunting. Like many malicious activities that occur in those days, it is related to the COVID19 pandemic. Its purpose of simple: It checks if Outlook

Those that know Techrules at all know it as the Chinese company behind the micro-turbine-powered, fighter jet-inspired Ren supercar, but it’s making a push to be known far outside of supercar fanatic circles. The company is working to transform the ran… Continue reading Techrules looks to power everyday EVs and grids with micro-turbines
Easy access to reliable electrical power is something a lot of us take for granted, but in developing countries or after natural disaster, it can be a rare commodity. [Daniel Connelly] has been working hard to develop infrastructure people can build themselves, and his latest project is a 200 W …read more

Lithium batteries and brushless motors helped make multirotor drones possible, but batteries only last so long. Liquid fuels have far greater energy densities, but have not been widely applied in these roles. [Tech Ingredients] has been experimenting with a compact gasoline-fueled generator, with the aim to extend drone flight times …read more
