How to Make Inexpensive DIY Home-Built Solar Panels with Damaged Solar Cells from Ebay
Mike Davis is an astronomer. To practice his hobby away from the light pollution of cities, he bought some land in a remote part of Arizona. But there was a problem: No electricity. But he's a resourceful fellow. He built some solar panels using inexpensive blemished and damaged solar cells from eBay! Read on for more photos and some technical details to give you an idea of how he did it. I bought a couple of bricks of 3 by 6 mono-crystalline solar cells. A solar panel is really just a shallow box. Next I cut two pieces of masonite pegboard to fit inside the wells. I laid out the cells on that grid pattern upside-down so I could solder them together. I used a low-wattage soldering iron and fine rosen-core solder. Here's what the solar panel looks like from the front. Here I am testing first half panel outside in the sun. I drilled a hole in the back of the panel near the top for the wires to exit. [...] Here is the finished product, producing 18.8 volts and 3.05 amps in the sun.

Welcome to The Sietch - Projects Build Your Own Solar Battery Charger First we need an old window, I got mine from a construction site. Its your basic old nasty basement window. Make sure you wash both sides of the glass well with soap and water and window cleaner, more dust means less light gets through to your solar cells. Next take your multi-meter and sit in a sunny spot (or under a flood lamp) and check all your cells to make sure they get about .5 volts per cell. Build a solar panel Make your own solar power or solar heating panel. We've also a great selection of ready made DIY Solar panel kits to get you started. Learn how to connect solar panels together in series or in parallel Find out how to choose the right components for your solar kit by visting this handy web page - Solar power or lighting kit design instructions.

The Smart New Way to Go Solar posted by Dave Llorens on September 8th, 2010 It Sounds Crazy, But It’s True Here at One Block Off the Grid, we’re constantly striving to demonstrate not only how much money solar can save, but also make for households, so we decided to conduct a little experiment: let’s say you, the homeowner, had $20,000 to invest today. What would happen if you decided to put panels on your roof instead of putting it in the bank? Solar Water Heating Projects and Plans Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as $7000 by building your own system.

How to Make and Use the Solar Funnel Cooker The Solar Funnel Cooker How to Make and Use The BYU Solar Cooker/Cooler by Steven E. Jones, Professor of Physics at Brigham Young University (BYU), with Colter Paulson, Jason Chesley, Jacob Fugal, Derek Hullinger, Jamie Winterton, Jeannette Lawler, and Seth, David, Nathan, and Danelle Jones. Introduction A few years ago, I woke up to the fact that half of the world's peoples must burn wood or dried dung in order to cook their food. 7 Design Principles, Inspired By Zen Wisdom One of the best-known photographs of the late Steve Jobs pictures him sitting in the middle of the living room of his Los Altos house, circa 1982. There isn’t much in the room, save an audio system and a Tiffany lamp. Jobs is sipping tea, sitting yoga-style on a mat, with but a few books around him. The picture speaks volumes about the less-is-more motive behind every Apple product designed under his command.

s Online - Solar Powered Stirling Engine - (tripod not supplied) This solar powered Stirling engine offers a dramatic demonstration of energy conversion. The Stirling engine with its parabolic mirror, can be attached to any conventional camera tripod. 'Solar Sinter' by Markus Kayser is a solar powered 3D printer that uses sand as source material #3dprinting #environment #energy #rca Amongst the wonderful collection of work currently on show at the Royal College of Art, in the corner on the first floor sits an installation/object by Markus Kayser called Solar Sinter. An MA Design Products student project, Solar Sinter is probably one of the most inspiring projects this year, aiming to raise questions about the future of manufacturing and triggers dreams of the full utilisation of the production potential of the world’s most efficient energy resource - the sun. In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance. In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology. The Solar-Sinster uses ReplicatorG software, an open source 3D printing program.

BeerSci: A Pint That Fits In Your Pocket Nothing hits the spot after a long hike more than a beer, but lugging a six-pack through the wilderness isn't as appealing. Brewers have toyed with portable beer concentrates before—by evaporating the water from finished brews. But along with the water go the hops, which impart flavor. Pat Tatera of Pat's Backcountry Beverages developed a process to brew concentrate instead of beer. Kiss the Grid Goodbye: Power Your Home with a Bloom Box! Fuel cells have been a tantilizing technolgy for decades - powering space vehicles, but always a little out of reach for domestic or commercial use. I worked with Greenopolis Partner Plug Power for years - working to provide clean on site energy from hydrogen powered fuel cells. Now there’s the Bloom Box.
