FEATURES
Counting squares: a method to quickly estimate PWB trace resistance Complex geometries can be broken up into different size squares of copper to approximate the entire region of interest.Power to the people: the democratization of engineering When it comes to open source, software is years ahead of hardware. But with encouragement from established electronics-industry players and moves from makers and hackers, engineers could see open-source hardware and an increasingly democratized, communitybased approach worked into and enhancing their design cycles.
10 tips for maximizing battery life Selecting a low-power microcontroller is an obvious first step, but you can follow a number of software and hardware tips to ensure that every milliampere-hour of battery charge is utilized.
