Five key considerations for east-west solar design | PV Tech Around the world solar developers are turning array designs on their head and choosing to go east-west instead of south- or north-facing like their traditional cousins. While east-west solar arrays may have a reduced total output, the value of the electricity they produce is inherently higher in most markets – They are generating more

Radar motion detector

I needed a motion detector for Arduino. I saw a cheap Microwave Radar Induction Switch Human Motion Sensor Module at DX (similar also available at Banggood at pack of 5). It advertises High Sensitivity for Arduino, Long Sensing Distance, Wide Sensing Angle for Detecting Moving Objects. Using this is a microwave sensor module that specifically

Finding the right power supply technology for your design | EDN In 2016, each person on the planet purchased an average of 111 semiconductor chips or integrated circuits. As the number of chips climbs, so does the need for greater power, space, and cost efficiency. In response, power device manufacturers have continued to evolve silicon-based technologies and develop new, wide bandgap materials such as gallium-nitride

Friday Fun: All The Simpsons Predictions That Came True | Time With 28 seasons and counting on the air, The Simpsons is undeniably a television phenomenon. In fact, throughout its more than 600 episodes, creator Matt Groening and his team have been so on top of the country’s cultural pulse, they’ve even managed to predict several major historical events — along with a few less

13 Companies announce NB-IoT Chips | Creative Connectivity With thirteen different companies bringing chips to market, that’s an investment of around $200 million. Add to that the costs of the standardisation process, infrastructure development and initial market trials and it’s clear that somewhere between $500 million and $1 billion has already been spent on getting NB-IoT to the point where it is

The day that changed your phone forever | TechCrunch It’s the 10-year anniversary of the original iPhone SDK. I don’t think it’s an understatement to say that this release changed a lot of people’s lives. iPhone at the end of June 2007 was a glimpse of the future. A couple of months later, the entire native app experience was unlocked.
