How to- Wind Turbine Made from Scrap Metal... This is my first Instructable so bare with me. This following Instructable is for A Wind Turbine that i Designed and Made out of Salvaged and Recycled Materials Because of the nature of the materials,everybody building them this way will all be different, don't let how i made this turbine affect how you make yours. build it with what you got. Wind turbines are not only Great to make but if made right can be good source of electricity. The way i will be using this Electricity is this. This is a simple wind turbine Design that i built in less than 1 day. MATERIALS (I cant really give any specific lenghs and sizes because... everybody is going to be different ... (ill keep this instructable just about the turbine for now so at this point i wont include all the batteries and instruments like the inverter or the voltage regulator) I should also mention This Turbine Project Costed Me 'Little to Nothing' I used Basic Tools In building this Wind Turbine Stay tuned for Power Output Readings
Make an Airsoft Machine Gun from a Soda Bottle Several months ago I posted a project showing how to make a 'cloud' BB machine gun with a built in air supply out of PVC. That project, while very entertaining, cost $50 in parts and took several hours to complete. More recently I have resumed experimenting with BB machine gun designs with the goal of making them as inexpensive and easy to build as possible. The model that is made in the above video can be assembled in under 5 minutes, uses only four parts, and costs a total of about $15. If you have not seen my previous BB machine gun project you can take a look at it by clicking This Link. This airsoft gun is a bullpup design, meaning that the pellets enter the barrel from behind the trigger. Parts Required: Please remember as always to share this article with others on Facebook and Twitter, and if you really want to support my projects, submit this article to other sharing sites sites such as Reddit and Digg. Until next time, -NH

How to build a wind turbine. Here we are going to make the two disks that the turbine blades fit on. First of all, mark a centre point on your MDF board. Use a compass to draw a circle with a radius of 160mm. Using a band saw, cut the circle out and use a sander to smooth the edges. Trace around the circle and use it to produce another disk of the same size. Find the centre point of these circles and use it to draw a 5 pointed star on each one. At the end of this step you should have 2x MDF circles split into 5 segments. The Dream Herb &Other Lucid Dreaming Supplements The latest trend in lucid dreaming is the prescribed use of supplements to increase dream recall and trigger more dreams where you become aware you are dreaming. These supplements, which include herbs, enzymes and Flintstone vitamins, can greatly increase your chance to go lucid. But they will not do the trick alone. In a nutshell, these supplements are worthless if not taken with the right mindset, as well as more traditional forms of lucid dreaming induction. At best, a supplement taken without mental preparation will increase the chances for a beginner lucid dreamer to be jolted into lucidity – but the lucid dream scene that emerges may be difficult to handle due to the beginner’s own inexperience with juggling the rawness of lucidity. However, taken with intention, respect, and as part of an ongoing mind-training program, these supplements may enhance the opportunities to work with self-awareness in the dream. OK, that said, lucid dreaming supplements can make your mind go pow.
Cardboard Savonius Wind Turbine Goal: build a Savonius wind turbine made out of cardboard to see whatworks. This is for the turbine only and not the generator itself. The main photo you see is the goal. The need for a working model grew out of frustration trying tojury-rig various designs of a Savonius turbine that in the end wouldnot turn at all in the wind. Some Initial Botched Designs Shown below are several botched designs. The second design is all cardboard and looked really sharp. it didn't budge an inch in a very strong wind. In the third one I added parts of the dryer vent tube to the cardboard mill and that worked a little bit but there was resistance on the back side coming into the wind. At this point, I decided that I had to go back to the drawing board with a simple model to see what had a chance of working.
DIY Wind-Powered Water Pump The biggest problem with this wind-powered water pump design is that every single part of the assembly is a bit wobbly, and all the wobble eats up a lot of the wind energy that should instead go into pumping water. To solve this problem in the next version, I would: 1. Use a sturdier tripod. 2. Use a bicycle rim that isn't warped. The bottom rim in this project is badly bent from some bike accident, and the motion it makes wastes wind energy. 3. Any solutions to the above would be appreciated.
The Triptych Enigma by Richard Cassaro Classicist Richard Cassaro is a specialist on ancient religions and secret societies. His new book, Written In Stone, reveals never-before-seen visual evidence of a “secret code” hidden in plain view in the architectural facades of the world’s most famous Gothic cathedrals. He says the code conveys an ancient message to posterity which was fully intended by the Freemasons who scholars say built these sacred structures. For a powerful preview, visit www.DeeperTruth.com and download his illuminating PDF Report: Breaking The Cathedral Code, Freemasonry’s Triptych Secret Revealed. An unprecedented new archaeological discovery has been made that ties the world's ancient pyramid-building civilizations together and shows they all practiced the same advanced "Universal Religion." The discovery, on the surface, is a seemingly simple one: it is the discovery of a key architectural parallel they all shared, and which is still visible in the ruins of their temples. You don't have a soul.
Maquette d'une éolienne / Construire une éolienne - Fabriquer une eolienne à axe vertical Page1 (précédente) | Page2 Maintenant je peux donc couper et coller les tuteurs en bois de manière à solidifier les pales et à les positionner correctement. J'ai donc collé deux tuteurs (préalablement coupés) aux deux extrémités des pales ( je les ai laissés dépasser de deux centimètres sur un côté, de manière à pouvoir fixer l'extrémité la plus longue sur la croix centrale). J'ai donc par la suite relié toutes les extrémités aux deux croix centrales: une en haut, une en bas et ainsi fixé les quatre pales ensemble. Enfin, j'ai récupéré un petit moteur électrique d'un jouet d'enfant : il me servira de génératrice. Des engrenages se trouvent dans le compartiment noir de manière à démultiplier les tours (comme une chaîne de vélo avec les plateaux). Comme vous avez pu le constater, je n'ai pas fait l'ossature bois sur la maquette. Page1(précédente) | Page2
Construire une éolienne à axe vertical Accueil » Fiches techniques » L'énergie et la motorisation Présentation Cette fiche contient les plans pour vous fabriquer une petite éolienne à vitesse constante. Le but est d'arriver à la faire avec du matériel de récupération. Principe de fonctionnement Quatre pales en forme de godet tournent sous l'action du vent (fig. 10). Liste des matériaux Construction des pales Elles sont au nombre de quatre et sont taillées dans de la tôle de 2 mm d'épaisseur. Les supports de pales Support inférieur Support supérieur La croix de liaison Biellette et accessoires Le socle Il se compose de quatre pieds reliés par deux plateformes. Position des pales en fonction du vent Principe Pour la suite Pour que l'éolienne puisse faire tourner un alternateur il faut rajouter une poulie U à gorge trapézoïdale sous la plate forme inférieure.
