This tutorial resume common steps to setup a basic connection for a Raspberry Pi board to the net using SSH, VNC and video streaming from a camera module. Most of this information is broadly available on the internet with this article being a review to easy and particular implementation. Prepariong the Raspberry Pi Basic setup: Raspberry Pi board. SD min 4Gb. Download Software Camera module with Flex Connector. Charcher or DC supply. Wi-Fi dongle or ethernet cable. Here how to… Read More »Raspberry Pi: Configuring SSH, VNC and Camera Module Streaming
Leap Motion its a very simple and cheap motion sensor for workstations
optimized to detect hand movements, the development environment allows to
capture optimized raw data and used on endless aplications.
The case represent a kilo-class submarine totally submerged under a water medium. The interest data for this tutorial is the flow path over the submarine shape and how the water interacts, the pressure points on the structure and the turbulence generated.
Many robotic projects require the control of multiples digital and discrete outputs to work simultaneously, the motor interfaces are not an exception due big robotic instrumentation used today, the widespread Arduino control interface has the ability to handle steppers motors even with its own reference function librarys, but when it comes to a much more basic type of control over multiple speed’s motors some arrangements need to be done.The basic operation of a stepper motor and its advantages like position… Read More »Controlling multiple speed-independent stepper motors simultaneously with Arduino.
DOWNLOAD: Simple beginning 3D OpenFOAM Tutorial.pdf OpenFOAM (Open Source Field Operation and Manipulation) it’s an Open Source Software project claim to be one of the best CFD tools currently available, principally be its constant development and its highly technical structure, the fine implementation of common solvers and the possibility to edit and create equations and mathematical cases make OpenFOAM useful tool on researching. OpenFOAM is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the… Read More »Simple beginning 3D OpenFOAM Tutorial
DOWNLOAD: Advanced CalculiX Tutorial.PDF Usual FEA applications involve analysis where multi body assemblies are loaded to determine the contact behavior between each other, some of this data are friction, relative displacement and contact pressure. This kind of cases of study are specially complex and requires much more technological resources due to the nonlinearity characteristics of the case, where a slight change on the geometry, mesh or frontier conditions overcome on a totally different behavior.CalculiX offers a highly custom process to… Read More »Advanced CalculiX Tutorial
Impact its an explicit finite element program wich development and final caracteristics are higly admirable by the way it focus on a simple, yet powerfull structure to solve real world numeric problems under the Time Explicit regimen. The programing language is really simple and can be read and understood from scratch, allowing the user to be more in contact and in control to the analisy’s structure and variables. The program documentation its already on the web and can be get… Read More »First IMPACT Finite Element Program tutorial.
NetGen it’s a powerful 3D tetrahedral mesh generatorl that can handle complex geometries and a great variety of meshing options, the tetrahedral meshs as those created with Netgen are the best option on the selection of a discretization theorem for a non conventional bodycas long as it can handle a decent meshing density , wich it’s possible with the use of current medium-high level processing units. The tetrahedral elements can adjust more easily to the curves and spline surfaces of the model, preserving its proportion form.
The documentation for how to do this is already on the Internet for all of you who knows how to get it, the issue is in all these incomprehensible or wrong sources which can waste our time. Older versions, different programs or libraries, different platforms or just poor documentation is normally found.
Fixing all this here is Tutorial of how to do it easily:
Blender it’s a huge 3D design platform that can be used as an extension of all specialized CAD programs. Any 3D model can be imported in to blender and can be rendered in to any 2D image or animated video, the use of lights, cameras, and custom textures make blender the finest way to make high quality blender in any system. Blender capabilities are in constant grow and new users can found alot of information about how to start using… Read More »Rendering with BLENDER Tutorial
