Portable Sun Tracking Solar Panel With A Windup Clock Drive. I've just designed and built a homemade solar tracker than can be easily set to accurately align to the altitude of the sun (as it changes daily, with the seasons), and also faithfully track the sun, from sunrise to sunset. The tracking ability of the panel provides about 40% more power than a fixed panel.
Another little-known advantage of sun tracking solar panels is that they run cooler, which enhances their output, versus rooftop mounted panels, or panels flat on the ground, which tend to build up a considerable amount of heat. The lightweight, but sturdy device is a real workhorse, ready to provide power in the field for contractors, third world homesteads, camping trips, vacation cabins, scientifc research field stations, recharging electric powered radio controlled model aircraft, and sound systems for park events. 21 tooth gear: Part Number: A 1T 2-Y24021 36 tooth gear: Part Number: A 1T 2-Y24036.
DIY High-Speed Book Scanner from Trash and Cheap Cameras. I love books. There is some truly fantastic knowledge and information hidden out there in hard to find, rare, and not commercially viable books. I find that I want my books with me everywhere. But that's where the problems begin. Buying, moving, storing, and preserving books means environmental costs... and when I loan a book to a friend, I no longer have access to it. Digital books change the landscape . UPDATE: We've outgrown the Instructables commenting system. UPDATE: If you're actually planning to build one of these things, you really should visit DIYBookScanner.org.
I've built two of these things now, and this instructable covers the best parts of both of them. Download a sample here.Download the entire book (115mb) here. We have written some open-source, free software to convert the images from your scanner into PDFs. EDIT: Many people have commented that an automatic page flipper would be faster.
