As electronics applications continue to become more compact and has more and more features in same package (think about modern smart phone or tablet), requires system engineers to use multiple power rails and mixed disciplines of circuit design (mix both analogue and digital parts tightly). A typical tablet will consist of items such as a →

Sometimes there is need to measure power going to different devices. Measuring DC power consumption is pretty easy, but when you try to do the same for AC circuit, things start to become complicated. How to Measure Electrical Power article will discuss best practices for making electrical power measurements, starting with power measurement basics and →
http://kukuruku.co/hub/diy/usb-killer It is well known fact that USB security is broken. So when you plug in unknown USB stick to your PC, you can get viruses to your PC OS and firmware. But can it seriously physically damage your PC. The designer of this gadget was thinking of this possibility and built such evil fake →

Is Arduino used in comercial applications you might ask. It is true that you aren’t going to go to your local big-box electronics store and find many (if any) products that have an “Arduino Inside” sticker, because Arduino is a prototyping platform. Arduino is a widely seen as targeed to hobbyists, but I would say →
The world of microphones is changing at least on handheld gadgets. MEMS Mics Taking Over article is telling that almost every mobile device has ditched its old-fashioned electret microphone invented way back in 1962 at Bell Labs. Most microelectromechanical (MEMS) microphones just copy the basic principle driving electrets, electrically biased diaphragms whose capacitance changes as →
What could be considered a reliable design nowadays? It is seems to be that thing are somwwhat different in today’s interconnected world compared to earlier times. Reliability Definition Is Changing article at Semiconductor Engineering magazine is a good introduction on what is changing in embedded systems design. The complexity and vulnerabilities in systems are raising →
Why do digital oscilloscopes appear noisier than traditional analog oscilloscopes? In EEVblog #601 – Why Digital Oscilloscopes Appear Noisy posting Dave busts the myth that digital scopes are noiser than analog scopes, and demonstrates what inherent advantages digital scopes can have over analog scopes in terms of true waveform capture. And how long exposure camera shots →
