How To Destroy an Arduino Board
Developers that are approaching electronics for the very first time have a lesson to learn; and this usually happens the hard way. Wiring a circuit incorrectly, and you can potentially destroy your Arduino board. When it comes to mistakes, hardware is generally not as forgiving as software. This tutorial shows the most common ways you can accidentally destroy an Arduino board; and how to…

A Bestiary of Alternative Game Controllers
—
Many game developers are suspicious about alternative controllers, believing that since they can’t be easily mass produced, they are useless. Well, this is the story of how an Arduino got me to San Francisco for free. Twice.
