Start-up develops special lens for 3-D photography and film

Until now, photographers and filmmakers had to use special equipment if they wanted to change the focus area in post-processing or reproduce an object three-dimensionally. The start-up K-Lens has now developed a special lens that can turn any standard camera into a 3-D camera. What began as a research project of the Max Planck Institute for Informatics and Saarland University, and was developed further with the help of the IT Inkubator, is expected to become available as a commercial product…

Screaming Circuits: Make that Three QFNs

It’s a new weekend, and I’m back to my obsession with stepper motors. If you haven’t read part one of this series yet, go back and read it here. That’s not an order; more of a plea. In any case, I’ve nearly completed the schematic now. It’s got four sheets. One for the FPGA, one for the stepper driver, one for the power supply, and one for switches and indicators. I haven’t yet put the switches in the schematic, because my choice…

Top Web Hosting Trends That We Have Witnessed So Far in 2018

A web hosting service is like a blank palette offered to the webmaster or web designer, who creates a website using the web host’s real estate. Apart from storing all the files and code that runs a site, a web hosting service also takes care of data, administration, security, maintenance and every other aspect of keeping the website up and running. Over the years, web hosting has seen several evolutions in its form and shape, and 2018 looks to be…

A new portable system of water quality assessment in developing countries

Credit: UPM Portable, easy-to-use water quality assessment systems are essential in developing countries where water access is limited and there is a risk of contamination. Researchers from Universidad Politécnica de Madrid (UPM) have designed a new system for assessing water for human consumption that is better than the systems currently available. The new system is three to five times cheaper, and is more sustainable and long-lasting, making it ideal for use in development aid. Non-potable water and poor sanitation are…

Paralympic snowboarder designs innovative gear—for rivals

In this Dec. 22, 2017, file photo, Mike Schultz, who is preparing to compete in the 2018 Winter Paralympics in South Korea, poses for a photo in his shop in St. Cloud, Minn. (Jason Wachter/St. Cloud Times via AP, File) Adaptive snowboarder Mike Schultz could very well have the winning formula at the Paralympics—whether or not he even crosses the finish line in first. He is the architect behind some of the most cutting edge prosthetic components out there, which…

How to be a more influential engineer – Square Corner Blog – Medium

Spoiler alert: you need skills. One of the most significant transitions for an engineer’s career is when they break dependence on senior team members and start to actively contribute to the team’s decision-making process. Once this transition is complete, the engineer is contributing to the team at levels far more significant than the code they can sling. They become a more productive team member and help unlock team potential by freeing up others’ time and effort. How do you get…

Flying cars eye takeoff at Geneva Motor Show

Pop.Up Next, a self-driving car and passenger drone by Audi, Italdesign and Airbus on display at the Geneva International Motor Show After gracing our screens for decades, flying cars are about to shift gears from dream to reality, with the unveiling of a commercial model in Geneva this week. From James Bond to The Jetsons, flying cars have long captured our imaginations, but now a Dutch company says they are almost ready to take to the streets, and the skies.…

Double disinfection treatment for safer drinking water

Credit: University of Eastern Finland In spite of good progress in water hygiene during the recent decades, contaminated water still causes millions of diseases every year. Most of these diseases are caused by enteric viruses, and better water disinfection methods could help prevent discomfort and even save lives. A new study from the University of Eastern Finland shows that a combined disinfection treatment with chlorine and UV radiation can be highly effective in…

Improved X-ray computed tomography for quality control of advanced manufactured parts

Credit: INTERAQCT A consequence of advanced manufacturing technologies is that some internal structures tend to be inaccessible and so quality control is necessarily destructive. This is clearly problematic for high-added value products, where customers nonetheless expect reliability and certified quality. Computed tomography (CT) has been heralded as an answer, making visible as it does internal structures and moreover combining dimensional metrology and material defect analysis. However, the technology has its limitations. The EU-funded INTERAQCT project created a research environment, harnessing…
