Thingiverse - Digital Designs for Physical Objects Build Your Own ELECTRIC MOTORCYCLE The finished project is a 1981 Kawasaki KZ440, converted to electric. It is powered by four Optima Yellow Top sealed (AGM) lead-acid batteries, that drive a Briggs & Stratton Etek electric motor. The speed of the motor is controlled by an Alltrax brand "AXE" programmable controller that can run at up to 48 volts and 300 amps. Contrary to popular belief, and electric motorcycle is NOT silent, but is CONSIDERABLY quieter than a typical gas cycle. The cycle is GEARED to 45 mph, has fairly good acceleration, no clutch or transmission. The cycle recharges from the wall, through a renewable energy program, and if there is a blackout, I can actually run my house off my electric motorcycle! In this Instructable, I'll walk you through the work required with the motor, batteries, controller, and mounting all components, including showing you some low-tech paper and cardboard "CAD" tricks. Your Project But what do you want? Give some thought to what cycle you would like to convert.
Digital Designs for Physical Objects The cat Made by PP3DP Sep 8, 2010 Source Description No description provided. Top ReplicatorG is a simple, open source 3D printing program - ReplicatorG Tweakie, Tweakie.CNC, CNC, router, mill, engraver, vinyl cutter, laser. Wiki RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017.

How to Build a Robot Tutorial - Society of Robots Introduction to Gears No good robot can ever be built without gears. As such, a good understanding of how gears affect parameters such as torque and velocity are very important. In this tutorial I will first talk about the basics of gears, how to use them properly along with simple equations, and then I will go into specific types of gears. Mechanical Advantage, Torque vs. Rotational Velocity Gears work on the principle of mechanical advantage. This means that by using different gear diameters, you can exchange between rotational (or translation) velocity and torque. As with all motors, by looking at the motor datasheet you can determine the output velocity and torque of your motor. With gears, you will exchange the high velocity with a better torque. Torque_Old * Velocity_Old = Torque_New * Velocity_New Torque_Old and Velocity_Old can be found simply by looking up the datasheet of your motor. 3 lb-in * 2000rps = Torque_New * 300rps 3 lb-in * 2000rps = 5 lb-in * Velocity_New
L’impression 3D, ce sera formidable… s’ils ne foutent pas tout en l’air ! | Dico Micro L’impression 3D est en train de naître sous nos yeux. Demain il sera ainsi possible de reproduire toute sorte d’objets chez nous aussi facilement, ou presque, qu’un texte numérique se couche sur le papier à l’aide de notre bonne vieille imprimante 2D. Les conséquences potentielles de la démocratisation d’un tel outil donnent le vertige et suscitent espoir et enthousiasme parmi les makers du monde entier[1]. Pour rappel, l’impression 3D est une technique qui permet de produire un objet réel à partir d’un fichier CAO en le découpant en tranches puis en déposant ou solidifiant de la matière (plastique, cire, métal…) couche par couche pour, en fin de compte, obtenir la pièce terminée. C’est l’empilement de ces couches qui crée un volume. Si le concept et la technologie vous semblent encore un peu obscurs, je vous invite à regarder cette courte vidéo. Pour le moment on se déplace donc chez ceux qui disposent d’une telle imprimante, imprimante encore rudimentaires dans ses possibilités.
Build Your Own CNC Router, CNC Machine, or 3D Printer EMC² et LinuxCNC Samedi, 19 Février 2011 21:10 Benjamin Voilà une découverte qui m'a rapidement conquis. EMC² est un logiciel open source permettant d'interpréter les programmes GCode et de commander une fraise numérique CNC. Ce logiciel tourne sous linux. Lien de linuxCNC où vous trouverez le cd d'installation à télécharger gratuitement Les avantages En plus de la gratuité du logiciel, j'ai constaté rapidement que ma machine avait moins de vibration en utilisant EMC². J'ai également trouvé le logiciel très intuitif et comme nous allons le voir, configurer le programme pour commander une CNC est très simple. L'écran principal possède une vue simulée de la pièce que l'on va usiner et montre l'état d'avancement lors du travail. Le logiciel repose sur un OS récent ce qui permet l'utilisation de clé usb, du réseau, ... pour communiquer les fichiers. Configurer une machine Pour cet article, nous allons voir comment configurer une machine CNC dans EMC². 1. 2. 3. 4. 5. 6. 7. 8. Bon amusement! Liens
