Build an Amazing Tesla CD Turbine

Build an Amazing Tesla CD Turbine
Build a real working turbine from recycled CD's! This Tesla CD Turbine is based on the Tesla turbine, which was invented by Nikola Tesla in the early 1900's. Tesla's pumps and motors were unique in that they only used discs, and took advantage of the boundary layer effect. His smallest designs were over 100 horsepower. This Instructable is an introduction to my recently developed Tesla CD Turbine, which is made from CD's, CD spindle, pipe fittings and glue. The basic model Tesla CD Turbine shows how the boundary layer idea works to deliver power. The advanced model has many cool features, such as the use of neodymium magnets to separate the CD's with the correct gap and a Magnetic Coupler to attach implements, and much more. My next CD Turbine Instructable shows how to make a Magnetic Disc Pack and Magnetic Coupler for more advanced CD Turbine experimentation. However, please be forewarned that this turbine on air pressure is not really a kid's toy or particularly safe to operate.

How to grow alum crystal... Coffee Filter Roses Back in my failed former days as a window dresser, I got some good advice from Tanja, the Grand Dame of the cosmetics department. Originally from Romania, Tanja was widely renowned for her eyebrow waxing skills and had arrived at a point in her career when she only had to take one appointment a day, then happily dragged it out all afternoon. Most of the time was spent smoking and laughing and singing gypsy folk songs about beet salad, then more smoking and dispensing advice about important things like men, business, and unwanted hair. Of the many things I learned from Tanja, there are three golden nuggets that stand out; Never brush your teeth with blue toothpaste.Men with excessively bushy eyebrows are likely to cheat on their wives.Women will buy anything wrapped in roses *Women married to men with excessively bushy eyebrows should expect a lot of roses. A week after Tanja dropped that old chestnut, my new boss gave me the task of revamping a central display table. SHAZAM! Materials: 1.

Crystal Growing by Thames & Kosmos Project Funded! Thanks, Kickstarter backers! | Treefort Five We did it! Treefort Five has officially been funded, and at 511%! It’s been a very busy few months getting this idea up and running and I’m so thankful for all the love and support! Backers, you really have made my daydreams a reality and I can’t wait to reward you for your support. So, what are the next steps? “So you’re over 500% funded, where’s that all going?” All of that extra funding is going toward bulk ordering larger quantities of materials for boxes (I can now order a run of 100+ rather than just 50 at a time), while also funding upcoming boxes. And after all of that, a few things to keep in mind: “So how can I keep up-to-date with Treefort Five’s progress?” And that sums it up! Thank you all again from high up in Treefort Five! - Danielle Like this: Like Loading...

Home Help : How to Replace a Lamp Socket How to Build a Lamp A 3D printable AEP7 laser pistol (Fallout) A fully 3D printable version of the AEP7 Laser Pistol from fallout 3 and New Vegas. It can be printed in around 30 hours and requires 1kg of material. It requires a lot of support and is challenging to print, but the pay-off is most certainly worth it. All the files to build it can be found at my thingiverse page It was painted using acrylic paint and weathered with a small paintbrush and black paint. It has a working laser diode (else it wouldn't really be a laser pistol). Mini Compressed Air Turbine Les projets et systèmes de détection d'ovnis Les projets et systèmes de détection d'ovnis Dans l'histoire de l'ufologie nous avons assisté à la mise en place de nombreux projets de détection des phénomènes ovni. Il existe sur le Web quelques sites qui traitent des détecteurs d’O.V.N.I. Ces appareils seraient en mesure de détecter la présence d'un O.V.N.I. dans un secteur restreint. De plus en plus perfectionnés ces systèmes peuvent être automatisés. Jean-Christophe Doré, à Rochefort, avec ses différents modèles de stations automatique de détection d'ovnis, qu'il a créés et mis au point seul (son site) Les effets Electro-Magnétiques (EM effects) font partie des indices quantitatifs rapportés dans les RR2. Projets de détection instrumentée L'idée de stations automatisées de détection de PANs s'est assez rapidement développée en ufologie, dans les buts d'offrir des données : Exemples de projets de détection automatisée: Le projet Pounce (USAF) en 1952 Hughes Aircraft construisit le système radar utilisé dans les F-94C.

Automatic Face Detection in Photos with PHP – Corpocrat Blog I have always wondered how to detect faces automatically with php script. I have seen in many photo sharing and social network sites automatically detect a face and tag a name after being uploaded. In this article, i will explain how possible this task can be achieved with simplicity with OpenCV and PHP Facedetect extension. Goal To auto detect faces in a photo and draw pink box around the faces with a php script running a linux centos server. Requirements - Linux server running Centos with SSH access - PHP/Apache - GD Library - OpenCV [Download] - PHP Facedetect extension [Download] PHP facedetect extension is very simple. Installation We install opencv and then we compile the php facedetect extension with php. How to Install OpenCV If you are running centos then one single line will install opencv. yum install opencv OpenCV may also need the following depencies to work properly and you will need to install them as well. For more installation instructions on linux see here How to test run OpenCV

Forêt, mèche : choisir les bons forets et mèches - Outillage Vous devez attaquer un chantier et donc investir dans du matériel ; parmi les outils essentiels, vous devrez acquérir des forets pour percer les matériaux divers que vous rencontrerez lors de la construction ou de la rénovation. Choisir un foret ne se fait pas à la légère. En effet, votre choix conditionnera la précision, la qualité et la facilité du travail. Le choix d'une mèche ou d'un foret se fait en fonction de plusieurs critères : Le matériau à percer; le type de perceuse ou perforateur que vous avez; le diamètre à percer; la fréquence d'utilisation. Voyons avec la marque Fischer Tout d'abord, vous devez définir quel type d'emmanchement vous possédez sur le mandrin de votre perceuse. Une fois l'emmanchement choisi, le type de matériau sera décisif. Voici un tableau qui récapitule les matériaux et les forets adaptés. Fisher développe de plus un nouveau foret 4 têtes, extrêmement performant pour les matériaux type brique, parpaing et béton. Foret SDS +4 Foret CTS super béton Foret SDS Foret CT
