Discover your inner geek with Make magazine.
Make is a quarterly magazine published by O'Reilly Media that focuses on do-it-yourself projects involving computers, electronics, robotics, metalworking, woodworking as well as other crafts. Think of it as a younger hipper Popular Science.
From simple to complex many of the projects feature things you can do with cheap materials and household items. Did you know you can develop black & white film using coffee and vitamin C or charge up your iPod with an onion and Gatorade? Do you miss your cat when you're at work? Well you can build the Kitty Twitty - a cat toy that will send you a message via Twitter whenever your cat plays with it.
The skill level for most projects is high school age and above but they do feature some great ideas for younger kids - perfect for science fair projects.
The magazine has photo essays as well as regular columns on technology and reviews of products and books. The web site has lots of additional ideas, video content, podcasts and one the most popular DIY blogs around.
The magazine also sponsors the annual World Maker Faire - a celebration of arts, crafts, engineering and science projects. Part science fair and part carnival, last year's Faire included Rubot, the world's fastest Rubik's cube solving robot, electric chariot racing and a musical performance accompanied by a synchronized lightning storm created with several Tesla coils. The next World Maker Faire will be in New York September 17th and 18th 2011.
