How I built an electricity producing Solar Panel Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. I built a wind turbine to provide some power on the remote property. Here is a video of the solar panel set up and in use on my remote, off-grid property. Let me state up front that I probably won't be able to help you out much if you decide to build your own solar panel(s). So what is a solar panel anyway? I started out the way I start every project, by Googling for information on home-built solar panels. After a while, I came to some conclusions: <a href=' seller. A solar panel is really just a shallow box.
Mini Bio-gas plant using food waste, decomposable organic material and kitchen waste I have been searching for some method of using the food waste, decomposable organic material and kitchen waste efficiently, and came across information on producing bio-gas from organic waste. The bio-gas produced from food waste, decomposable organic material and kitchen waste, consisting of methane and a little amount of carbon di oxide is an alternative fuel for cooking gas (LPG). Also, the waste materials can be disposed off efficiently without any odor or flies and the digested slurry from the bio-gas unit can be used as an organic manure in the garden. Components of the Bio-gas Plant The major components of the bio-gas plant are a digester tank, an inlet for feeding the kitchen waste, gas holder tank, an outlet for the digested slurry and the gas delivery system for taking out and utilizing the produced gas. This project is also useful for students to have a hands-on learning experience in constructing a Mini Bio-Gas Plant, using locally available material. Material Required: 1.
Homemade Lotion Recipe - How to Make Your Own Lotion If you are still using the cancer-in-a-bottle store bought lotion on yourself or your family, there are super easy natural alternatives! In fact, this recipe is incredibly simple to make and all the ingredients are available here. It only has three basic ingredients and literally takes ten minutes to make! You can customize your lotion to your skin type and desired scent, and you can even make it for baby (calendula and chamomile…) There are endless variations, but some of my favorites are: Calendula and Chamomile for babyRosewater and Almond OilPeppermint, Wintergreen, and Ginger for sore musclesCoconut and Calendula for faceMint and green teaLavender and vanilla I’ve included my basic recipe below. NOTE: This is an improved recipe since many people were having trouble getting the temperatures exactly right to get the lotion to emulsify (as per the comments below). Organic Homemade Lotion Basic Ingredients: Note: All ingredients and many essential oils are available here.
Amazing plasma globe tricks that you never knew before!!! The thing you must have is the plasma globe itself, you can use any plasma globe you have - from little tiny USB plasma globe all the way to the gigantic laboratory plasma globe, the plasma globe I used is called "Plasma 360". Also you need some more things if you want more fun out of your plasma globe... Get some of those thing you have around your house! I am very sure you have one of any of those things in your house! - florescent tube (any size will do) - Energy saver lamp (compact fluorescent bulb) (any type will do) - Cold cathode tube (any color and type will do) - Xenon tube (you can find one inside a disposable flash camera) - neon bulb (I used some tiny ones) - LED's (use cheap junk LED's, you will find out later in this instructable) - LCD screen (I used one from broken electronics) You could also try experiment using other things like... - Neon sign
DIY Solar Air Heating Collectors: Pop Can vs Screen Absorbers Search The Renewable Energy site for Do-It-Yourselfers Page Contents: The test collectors: Pop can collector on left and screen collector on right Collector Basics There is a lot of not so good information out there on what makes a good solar air heating collector design, so I thought I would include a little info on solar air collector physics, what makes for a good design, and how one can measure and compare collectors accurately. How do collectors work, and what makes a good design? On just about all solar thermal collectors, the sun shines through the glazing, and hits the collector absorber heating it. In full sun, the incoming solar energy is about 1000 watts per square meter of collector area. Most of this 850 w/sm that made it into the absorber end up going down one of two paths:: one part is picked up by the air flowing through the collector and ends up heating the room, and the other part ends up being lost out the glazing. The heat output the collector can be calculated as: 1. 4.
Air Filter for your room on the Cheap 2 hours build time Parts - Tools - Cardboard box of some sort. Just big enough to fit the fans. Improvements for my next version. - Add a switch to turn it on and off.- Add a Fan speed control. - Add a LED kill switch or use fans with no LEDS (Hard to fall asleep sometimes but is good for a night light)- hook to a 12 volt DC to AC power adapter so you don't need to run a wire from the computers power supply. Build this open source DIY wind turbine for $30 Getting started with home wind energy projects can set you back a pretty penny if you buy a finished product, but if you're a little bit handy and don't mind scrounging for materials and getting creative in the garage or backyard, you can try your hand at building one of these DIY wind turbines for about $30 in materials. After all, it is #iheartrenewables week! We've previously covered Daniel Connell's open source concentrated solar collector plans, but now he's back with another great DIY renewable energy project, a vertical axis wind turbine based on the Lenz2 lift+drag design. Connell's design calls for using aluminum lithographic offset printing plates to catch the wind, which he says can be obtained cheaply (or possibly even free) from an offset printing company, and a variety of hardware and a bicycle wheel. "The turbine uses the ~40% mechanically efficient Lenz2 lift+drag design. Here's a little clip of the vertical axis wind turbine being challenged by strong winds:
Pepakura File Index - Halo Costuming Wiki To help newcomers to Halo costuming, we've gathered all of our known Pepakura files that we could post here. For the uninitiated, you're best off grabbing a set of basics and making them, then later making a set of whichever permutations you want. You'll want to practice anyways... We ask that you don't delete anything here. Be respectful, and have fun. Halo Pepakura Database Edit Due to many files here now having dead links, and the difficulty of finding individual files amongst forum threads, a Database has been created to collate these files into a singular, easy to access location. You can access this Database at the following link: Pass the word...

DIY Open Source Solar Concentrator Tutorials Now Available © SolarFlowerEver wanted to tinker about with a homebrewed solar energy system? Then this project, SolarFlower, might be just the ticket for you. The creator, Daniel Connell, has been working on his concentrated solar energy collector for several years now, and has just launched a web home for it, complete with detailed tutorials. SolarFlower is: "An open source solar energy collector which tracks the sun automatically through a simple non-electrical mechanism. According to Connell, the potential uses for these devices include electrical generation, water purification, cooking, bio-char and charcoal, food dehydration, heating, gasification, and just about anything else heat can be used for.
$50 fire pit using concrete tree rings. We recently moved from the remote north woods of Wisconsin where people create great lakeside campfires by digging large fire pits into the ground and lining them with large rocks. We now live in a residential neighborhood in the Central Valley of California. Here, campfires are confined to pre-built pits or structures. People build only small controlled fires to minimize the risk of sparks blowing into neighboring combustibles when the fire is left unattended. Even with these restrictions, our family still loves to sit outside around an evening fire in the backyard. Fortunately, while cruising the aisles of Home Depot recently, we saw concrete tree rings (circles that are used for flower beds at the base of a tree) on sale for $2 a section. Materials: Total cost: $50-$80 depending on your taste in stones.
