Project Build A Solar Panel: Step by step guide to building a solar panel with complete illustrations Introduction A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3.1 - 1.8 electron volts, of the visible region as shown by ACEPT W3 Group (1999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Significance of Solar Panels A solar cell, in itself, is of little value in our energy consumptive world.
myvu Crystal 701 iPod Edition For makers of wearable video displays—essentially, nose-mounted miniature video monitors with supporting frames, capable of letting you watch an iPod’s video without squinting at a tiny Apple screen—it has long been believed that mainstream popularity will come at a point when pricing and aesthetics become comparable to a good pair of sunglasses, rather than an expensive pair of goggles. Major strides have been made over the last several years, as companies such as Myvu and Vuzix developed lightweight dual-screen displays that looked like little more than an anonymizing black plastic bar in front of your eyes and ears, selling in the $200 to $300 range. While not attractive in the strictest sense of the word, the displays have become increasingly neutral, and by the end of last year rested on the fine edge of public tolerance. This year, for better or worse, manufacturers decided to design their way out of visual neutrality.
47 Sites Every Recording Musician Should Visit In a recent “Open Mic” we asked you, “Which music-related sites do you visit regularly?” This article is a summary of the great suggestions given in the comments to that article. You can make the list even longer by commenting on this article. As you’re reading this article, Audiotuts+ needs no introduction. 5 Fun things To Do on School Computers - Pahgawks Animations - StumbleUpon November 26th, 2010 I know it's been a while, but I'm reinstating my weekly blog post policy. This week will be about something I've wanted to write about for a while: School computers! They're just too easy to hack and do fun stuff with, especially because teachers are just so incompetent with technology sometimes. Anyway, tome for the top five! 1.
DIY Solar Still How To Make Your Own Distilled Water Make your own distilled water from stream or lake water, salt water, or even brackish, dirty water, using these DIY Solar Still Plans. With just a few basic building materials, a sheet of glass and some sunshine, you can purify your own water at no cost and with minimal effort. Distilled water is not just for drinking, and it’s always worth keeping a few gallons of it on hand. DIY Wearable Computer Turns You Into a Cyborg Someday humans and computers will meld to create cyborgs. But instead of waiting for it, Martin Magnusson, a Swedish researcher and entrepreneur, has taken the first step and created a wearable computer that can be slung across the body. Magnusson has hacked a pair of head-mounted display glasses and combined it with a homebrewed machine based on an open source Beagleboard single computer. Packed into a CD case and slung across the shoulder messenger-bag style, he is ready to roll. A computer is a window to the virtual world, says Magnusson.
Laser cutter, start slicing stuff for under 50 dollars There are many out there that are making things to win a laser cutter. Here is a project for those 500 that don't win, but still want a laser cutter for simple stencil cutting needs. This project was conceived during a chat with Alex where we wished we had a laser cutter and thought we could make one out of an etchasketch. Alex, this instructable is for you.
