15 Dangerously Mad Projects for the Evil Genius by Simon Monk is the Dangerous Book for Boys for technical hobbyists and makers! Or, to be more specific, mischief makers. Inside you’ll learn how to build a pistol-sized electrical coil gun that fires a small metal projectile up to 30 miles per hour. Listen to your mother: do not point this at your little brother’s face. Nor should you aim the medieval trebuchet you’ll learn how to build at neighbors or family members. The insanity doesn’t end there. The author will show you how to tear apart a leaf blower and turn it into a machine gun for ping pong balls. A radio bug, a laser voice transmitter, a laser-grid intruder alarm, a flash bomb, and many more DIY projects round out this handbook for mad-scientists-in-the-making. If it all sounds like lots of fun (until someone loses an eye), but you’re a little worried about your electronics skills — fear not! In his quest to spread mad science throughout the world, author Simon Monk has included an “Electronics Construction Primer” to get you started! As if all that weren’t enough, you’ll also learn how to work with the popular Arduino microcontroller board.
