How To: The Hardware Hacker's Introduction to Microcontrollers, Part One: Anatomy of an Arduino

In this article, I'll be explaining the basics of how microcontrollers work, physically and virtually. First off, microcontrollers are no simple thing, so don't be discouraged if you find it mind-boggling! The world of microcontrollers is fascinating, engaging, and an awesome hobby; it never gets boring. I'll be focusing more on I/O and analog based microcontrollers, such as those running Arduino, and using Atmel chips as examples (these are most commonly available, and easy to program).

Spice Rack Explosives: How to Make Gunpowder with Salt & Sugar

The best chemistry experiments are those you can perform with items already laying around your house. With only some sugar, salt substitute and an instant cold pack, you can make your very own gunpowder!

Samsung created quite a buzz when it debuted a built-in heart rate sensor on the Galaxy S5 back in 2014, but amazingly, not many other manufacturers decided to follow suit. It's really a shame, too, since data from a heart rate sensor would go perfectly hand in hand with the increasing fitness- and activity-tracking features that most smartphones sport these days.
