Arduino for commercial products?

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

MEMS Mics Are Taking Over

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

Reliability Definition Is Changing

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 Digital Oscilloscopes Appear Noisy
