Book excerpt: A man’s home is his castle, or so the saying goes, but could it withstand an attack by Attila and the Huns, Ragnar and the Vikings, Alexander and the Greeks, Genghis Khan and the Mongols, or Tamerlane and the Tartars? Backyard Ballistics author William Gurstelle poses this fascinating question to modern-day garage warriors and shows them how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes. Each chapter introduces a new bad actor in the history of warfare, details his conquests, and features weapons and fortifications to defend against him and his minions. Clear step-by-step instructions, diagrams, and photographs show how to build a dozen projects, including “Da Vinci’s Catapult,” “Carpini’s Crossbow,” a “Crusader-Proof Moat,” “Alexander’s Tortoise,” and the “Cheval-de-frise.” With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind many of the projects, and shows where to buy the materials. By the time they’ve reached the last page, at-home defenders everywhere will have succeeded in creating a fully fortified home.
Download or read book How to Build Treehouses Huts and Forts written by David Stiles and published by Rowman & Littlefield. This book was released on 2023-09-21 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: A treehouse is a wonderful idea, but how in the name of creation do you actually build one? In this delightfully illustrated handbook, David Stiles, the unofficial world grandmaster of the treehouse, shows how. Not assuming anything about the treehouse builder, Stiles starts with the basics: how to nail, how to buy wood, what kind of screws and nails to use. Then it's on to an A-frame design so simple that it can be built in a weekend out of four sheets of plywood, followed by lean-tos, a tree hut, and a Tarzan-style jungle hideaway. There are also forts of every description, including a 21-foot-tall lookout tower modeled on one George Washington built to keep an eye on the redcoats. Stiles also adds a design for a snowball catapult, an igloo and even a Nerf-loaded cannon. Written for children, with an adult peeking over their shoulder, Stiles's TREEHOUSES, HUTS, & FORTS is a dreamer's handbook, offering practical results.

Download or read book Adventures from the Technology Underground written by William Gurstelle and published by Crown. This book was released on 2009-02-04 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technology underground is a thriving, humming, and often literally scintillating subculture of amateur inventors and scientific envelope-pushers who dream up, design, and build machines that whoosh, rumble, fly—and occasionally hurl pumpkins across enormous distances. In the process they astonish us with what is possible when human imagination and ingenuity meet nature’s forces and materials. William Gurstelle spent two years exploring the most fascinating outposts of this world of wonders: meeting and talking to the men and women who care far more for the laws of physics than they do for mundane matters like government regulations and their own personal safety. Adventures from the Technology Underground is Gurstelle’s lively and weirdly compelling report of his travels. In these pages we meet Frank Kosdon and others who draw the scrutiny of the FAA, ATF, and other federal agencies in their pursuit of high-power amateur rocketry, which they demonstrate to impressive—and sometimes explosive—effect at the annual LDRS gathering held in various remote and unpopulated areas (a necessary consideration since that acronym stands for Large Dangerous Rocket Ships). Here also are the underground technologists who turn up at the Burning Man festival in the Nevada high desert, including Lucy Hosking, “the engineer from Hell” and the creator of Satan’s Calliope, aka the World’s Loudest Thing, a pipe organ made from jet engines. Also at Burning Man is Austin “Dr. MegaVolt” Richard, who braves the arcing, sputtering, six-digit voltages of a giant Tesla coil in his protective metal suit. Add in a trip to see medieval-style catapults, air cannons, and supersized slingshots in action at the World Championship Punkin Chunkin competition in Sussex County, Delaware, and forays to the postapocalyptic enclaves of the flamethrower builders and the future-noir pits of the fighting robots, and you have proof positive that the age of invention is still going strong. In the world of science and engineering, despite its buttoned-down image, there’s plenty of fun, humor, and sheer wonder to be found at the fringes. Adventures from the Technology Underground takes you there. • Launch homemade high-power rockets. • Catapult pumpkins the better part of a mile. • Watch robot gladiators saw, flip, and pound one another into high-tech junk heaps. • Dazzle the eye with electrical discharges measured in the hundreds of thousands of volts. • Play with flamethrowers, potato guns, and other decidedly unsafe toys . . . If this is your idea of fun, you’ll have a major good time on this wild ride through today’s Technology Underground. From the Burning Man festival in Nevada’s high desert to the latest gathering of Large Dangerous Rocket Ship builders to Delaware’s annual Punkin Chunkin competition (a celebration of “science, radical self-expression, and beer”), you’ll meet the inspired, government-unregulated, and corporately unfettered men and women who operate at the furthest fringes of science, engineering, and wild-eyed arc welding, building the catapults, ultra-high-voltage electrical devices, incendiary artworks, fighting robots, and other machines that demonstrate what’s possible when physics meets human ingenuity.
