Provides a collection of ideas for science fair projects and family activities, including making topsoil, understanding calories, and building a MacGyver radio.

The ultimate DIY project guide for techie dads raising kids in their own geeky image, in the spirit of The Dangerous Book for Boys Today's generation of dads grew up more tech-savvy than ever. Rather than joining the Little League team, many grew up playing computer games, Dungeons and Dragons, and watching Star Wars. Now with kids of their own, these digital-age dads are looking for fresh ways to share their love of science and technology, and help their kids develop a passion for learning and discovery. Enter supergeek, and father of two, Ken Denmead. An engineer and editor of the incredibly popular GeekDad blog on wired.com, Ken has created the ultimate, idea-packed guide guaranteed to help dads and kids alike enjoy the magic of playtime together and tap into the infinite possibility of their imagination. With illustrations throughout, this book offers projects for all ages to suit any timeframe or budget. With Denmead's expert guidance, you and your child can: •Fly a night-time kite ablaze with lights or launch a video camera with balloons •Construct the "Best Slip n' Slide Ever," a guaranteed thrill ride •Build a working lamp with LEGO bricks and CDs •Create a customized comic strip or your own board game •Transform any room into a spaceship •Make geeky crafts like cyborg jack-o'-lanterns or Ethernet cuff links Brimming with endlessly fun and futuristic tidbits on everything from gaming to gadgets, GeekDad helps every tech-savvy father unleash his inner kid-and bond with the next generation of brainiacs.

Unlock the secrets to creating random mazes! Whether you're a game developer, an algorithm connoisseur, or simply in search of a new puzzle, you're about to level up. Learn algorithms to randomly generate mazes in a variety of shapes, sizes, and dimensions. Bend them into Moebius strips, fold them into cubes, and wrap them around spheres. Stretch them into other dimensions, squeeze them into arbitrary outlines, and tile them in a dizzying variety of ways. From twelve little algorithms, you'll discover a vast reservoir of ideas and inspiration. From video games to movies, mazes are ubiquitous. Explore a dozen algorithms for generating these puzzles randomly, from Binary Tree to Eller's, each copiously illustrated and accompanied by working implementations in Ruby. You'll learn their pros and cons, and how to choose the right one for the job. You'll start by learning six maze algorithms and transition from making mazes on paper to writing programs that generate and draw them. You'll be introduced to Dijkstra's algorithm and see how it can help solve, analyze, and visualize mazes. Part 2 shows you how to constrain your mazes to different shapes and outlines, such as text, circles, hex and triangle grids, and more. You'll learn techniques for culling dead-ends, and for making your passages weave over and under each other. Part 3 looks at six more algorithms, taking it all to the next level. You'll learn how to build your mazes in multiple dimensions, and even on curved surfaces. Through it all, you'll discover yourself brimming with ideas, the best medicine for programmer's block, burn-out, and the grayest of days. By the time you're done, you'll be energized and full of maze-related possibilities! What You Need: The example code requires version 2 of the Ruby programming language. Some examples depend on the ChunkyPNG library to generate PNG images, and one chapter uses POV-Ray version 3.7 to render 3D graphics.
