Since the coil is wrapped around the tube from a plastic pen, and the iron projectile is inside the tube, it will fly along towards the coil. As all the energy from the capacitors will be spent in a matter of milliseconds, the coil should ideally be turned off by the time the projectile passes its center and exits out the other side of the tube.
Simon’s plans and walk-through are wonderful. I learned a lot reading the detailed but easy to understand instructions. He also selects parts and components that I am sure I can source locally and I love that he improvised brackets from a plastic drinking bottle.
I also learned that I will not be making a coil gun. That curiosity is now satisfied!
50 Model Rocket Projects for the Evil GeniusThe fun, hands-on way to learn about rocket science. Yes, as a matter of fact, is IS rocket science!

Thanks to everyone who stopped by the TAB/McGraw-Hill stand at Maker Faire last weekend in NYC to check out our books and say Hello!
Couldn’t make it to Maker Faire? No problem! You can still browse our Maker Faire online store and take advantage of the special show discounts and free shipping on all of the great DIY books we had on display.
The good news is that it’s actually easy to make one. And the starting point? A circuit with nine red LEDs and just the right spacing: our open-source Larson Scanner kit. With minor modifications— a software change and dumping the heavy 2xAA battery pack—it makes a pretty awesome tie.
And while you’re feeling all Kraftwerk-y, check out Kraftwerk’s way-cool Kling Klang Machine and generate your own robotic soundtrack.
15 Dangerously Mad Projects for the Evil Geniusby 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.
TAB is starting to plan for the 2011 NYC Maker Faire! Lots of cool things planned aroung this year’s MF - our first Meetup, the 2011 edition of the official Team TAB Maker Faire NYC skateboard, and more. See you in Queens!
