Raspberry Pi with Java 8

Youtube

This tutorial is designed to help you use your Java programming skills to create hobby projects using the Raspberry Pi as an inexpensive (35 euros) interface to the physical world. We will teach the concepts by demonstrating examples with working projects and source code. Some of the topics we will cover include: * Unboxing your Raspberry Pi and setting up Java * Electrical circuit design for GPIO * Using the Java 8 Device Access API * Programming common I2C devices * Device communication over HTTP, MQTT, and Web Sockets * Creating visual and touch UIs * 3D Printing custom hardware Coming out of this session you will have the knowledge you need to start building your own embedded projects for your home or office, and can leverage your Java programming skills to connect it to the Internet of Things. Start building the future now with Java 8 Embedded technology! Authors: Robert Savage Robert Savage is a Member of Technical Staff at AMX, LLC.

Blood Hit Green Screen Effect|Friends company|hamza db

Youtube

How to Make a Green Screen Green chroma key The green screen effect is a type of chroma key. The idea is to create a pure green background which is then replaced with whatever background image you want. This tutorial shows you how to set up a green screen (cheaply if necessary) and how to use it in your video productions. The tutorial includes: Planning the studio setting Green screen material Lighting the green screen Incorporating green screen footage into your videos More Tips There are numerous variations on the standard green screen technique and you will need to develop your own system based on the resources you have available. Whatever you do, remember the two most important considerations: The colour and lighting of the green screen needs to be as even as possible. You can't have anything in the foreground (i.e. part of the the subjects) which is the same colour as the green screen. Before you begin any construction, it's a good idea to plan your studio layout and green screen size. There is nothing worse than building a green screen which ends up being not quite wide enough. Set up your proposed studio area and camera(s). Go through every type of shot you could possibly want and measure the total required background area. Allow enough room to change your mind about framing or widen the shot more than you originally thought. Also, allow extra space to the sides of the screen to place lights. Ideally there should be some space between the foreground subjects and the green screen — this makes lighting easier. Plan your budget. Green Screen Material:- There is some debate over which materials are acceptable for use as a green screen. Many professionals will tell you that the colour must be just the right shade of green, or that the screen must be made of certain material. It is certainly true that some materials and colours are better, but in reality you can make an effective green screen from just about any smooth, green surface. If you really want the best possible screen you should do an Internet search for green screen material. There are numerous websites which sell specialist material and with a little research you can find something to suit your studio. Be aware that professional green screen material can be quite expensive. In the more likely event that you would like a cheap option to get started with, you will be glad to hear that it's not hard finding useable material. There are three main options: Use a solid material such as cardboard or wood, painted green. Use flexible or spongy material such as foam, spandex, etc. If you're going this way, you are probably better off to buy professional material. Use some sort of fabric. You can either buy green material or buy white material and paint/dye it green. Fabric Go to a good fabric store and look through the selection — you should be able to find at least several choices. The material should not be too reflective — this tends to create lighter "hotspots". Lighter, brighter green is better than dark green. Material which is crease-resistant is very desirable. Wrinkles are the enemy and you will appreciate material which can be set up and moved without destroying the smoothness. Heavy material is good for providing consistent colour, especially if there is any possibility of anything behind the screen showing through. However it can be prone to more creasing. If you need to pack up the material for storage or moving, roll it rather than fold it — this helps reduce wrinkling. It's a good idea to use a cylindrical object with a diameter of at least 5-10cm (2-4") to roll the material onto, for example, the heavy cardboard cylinders used as the centre of newsprint rolls. You may want to iron your material from time to time to keep wrinkles away. If you are going to paint or dye the material, make sure you will be able to iron it. Note than ironing a piece of material this large without creating new creases can be a challenge. Hang the material in whatever manner suits your situation. For example, you could use thumbtacks or a shower rail attached to the wall. To make a mobile screen, use two stands (such as light stands or mic stands) and mount a rail between them. You could also make stands from clothing racks, hat stands, or any similar type of frame. Solid Material Cardboard or wood has the advantage of providing a nice consistent surface, free of wrinkles. The disadvantage is that it's more difficult to pack up and move. Although you can use any light, bright green paint, it is better to use a tint designed for green screens. Do a search for "chroma key paint" to see some options.
