IS IT POSSIBLE TO MAKE A 3D PRINTER WITH YOUR HANDS?

The output of the first machines for 3D printing has attracted a lot of enthusiastic responses. Truly, this is one of the most striking developments of the IT segment in the early 21st century. At the moment three-dimensional printers are quite firmly entrenched in specialized fields of engineering, industry and other fields. Companies that need high-performance hardware manufacturer of small parts, willing to buy a 3D printer. The price component is of the order of 100 thousand rubles doesn't stop them, because tech device pays for itself.

With regard to household use, such investments can rarely be justified because the meaning in the acquisition of such equipment. The need for such a device is explained, generally, by curiosity and desire to experiment. Although, of course, there are many examples of when 3D printers are widely used in everyday life. Anyway, the techniques of independent production of innovative devices in recent years has gained a lot of followers. This fueled the interest in "three-dimensional" success DIY.

As usually happens in improvised creativity, the field to implement the ideas boundless. Each master develops its own recipes and technologies to bring your idea to life. And yet a 3D printer to fabricate without special textbooks and knowledge, it is impossible. Initially, an example for the first enthusiasts were the products of Z Corporation and 3D Systems. However, the most significant contribution to the industry of self-made devices made by the RepRap company engaged in the development of kits for printers three-dimensional printing.

In fact, before anyone who decides to make a similar product, faces a dilemma: to use kit, requiring only Assembly, or purchase components separately. The answer to this question everyone decides for himself, but a 3D printer with your own hands can be done only if you have the knowledge and technical skills that will be required in the manufacturing process.

In the original devices company developing software specifically designed for specific models. In fact, it is a simple program for 3D-printer, which are also called slicers. With such functions and handle applications of type Skineforge, Slic3r and Kisslacer. For productive work you will also need a 3D editor that will save presets in the STL file. It should be noted that when using large models, the printer may not perform the cutting because of the insufficient area of the platform. The solution to such problems lies in the elementary division of the virtual object into several parts.

Additionally, if you need some of the Arduino SCM and 3D Printer Acc, you could purchase at Banggood, which is one of the wholesale platform to provide you the low prices. Such as, Low ZVS, rubber pulley wheels, etc. 

Raspberry Pi 2: the use, installation and connection

Initially, developers planned a microcomputer as a cheap device for teaching pupils computer science. But something went wrong. "Raspberry" interested in a lot of people. Everyone's wondering what a micro-computer - the Raspberry Pi 2. The use, configuration and installation of this device we will consider below. And yet – a bit of history.

Raspberry Pi was developed in 2011. For several years it has undergone serious changes. Now this is a very interesting platform with lots of features called Raspberry Pi 2. The application of this charge is possible in all conceivable areas. It can be used as a production server of a "smart" home security system with face detection, multimedia centre and much more. The latest model Raspberry Pi 2 Model B+ has at its disposal a Quad-core ARM v7, 1 GB of RAM and a video card that can easily play Full HD videos. The USB connectors are in number of four pieces is also in place. To connect a monitor or TV, use the HDMI output.

Here things are not so simple. The original version of the microcomputer could not work on normal distributions. They had to create special versions of systems. All OS are based on Linux distributions. There is even a special version of ArchLinux and Kali Linux for the Raspberry Pi 2. Installing the OS on the Board by using a microSD card and special apps NOOBS. In the latest version of this device if desired quite possible to use as the OS system is Ubuntu and even Microsoft Windows 10. Due to this from the Raspberry Pi has become possible to make a home multimedia center. 

However, by default, strongly recommended to use Raspbian OS, specially created for this microcomputer. It is based on the well known Debian distribution. All controls are exactly the same as a normal Linux system.

For many it will be interesting to work with such an amazing electronic device. And not only so-called geeks (people who "turned" on his hobby). To anyone even slightly curious person will be interested to understand this "piece of iron". After all, for a nominal fee you can get a computer system, the second half conceding a huge stationary PC. Besides, many people will want to make your media center or to arrange to upgrade a car using Raspberry Pi. The use of the microcomputer in fact do much to make life.

It can also be used as an alternative to programmable electronic designer Arduino. Because the latter can act only as the control Board, while the Raspberry Pi is almost a full-fledged computer. It is popular among hackers with crackers, is based on it often make interceptors Wi-Fi traffic with passwords that are easy to conceal and only from time to time to collect data. Reflect the theme of the microcomputer in the television series about Hackers, "Mr. Robot", where the heroes used the device for remote technological sabotage. Oh and don't forget about the small cost that can afford to almost everyone. Especially fond of the inventors is that the use of Raspberry Pi and can multiply like anything.

Additionally, if you need to purchase some of the Arduino and SCM components, you could search at Banggood, which is one of the wholesale platform to provide you the low prices. Such as, smd led board, jumper cable wire, etc.

How to make a skeleton key for different locks

In life sometimes there are situations when a lock blocks the road and prevents. And if we knock the door is not desirable, then the only thing left is to pick the lock without a key. In this case, it is useful to know how to make a lock pick. In addition, a set of simple lockpicks would be nice to have a reserve somewhere in the far pocket. 

Before you make picks with your own hands, you need to understand which type of lock you need to open. The easiest way to work with cylindrical, they are the most simple and straightforward. The key to this lock is flat with teeth on one side. If the key has the shape of a long rod shaped with protruding barbs at the end, it is a lever lock. Each of them uses its own method and its skeleton key.

Many of those who are interested in how to make lock pick, mean cylindrical, or English, the locks - they are the most common and convenient. Skeleton key consists of two main parts – the rocker, which will need to click the necessary teeth, and the rotary plate, which rotates the lock cylinder. They are made of thin (0,5-0,7 mm) and durable metal. It is best to use Soviet or folding away the blade for hacksaw. In an emergency, if such is found, you can use any pieces of thin sheet metal. Swivel plate easy, for this a strip of metal the width of five millimeters bend at a distance of 7-10 mm from the end at a right angle to create leverage. The manipulator is more complicated – its shape must be such that using it to click on one or more cylinders of the locking system. In the simplest execution, you can make it just a narrow strip with a slightly curved end or thickening on it. At the very least you can use a wire or paper clip. If the pick is done with the hope of further use with different locks, then you can try to make a set of manipulators of various forms with several teeth, which will allow you to open almost any locks.

The main difference between a lever and English castles that the larva cylinder lock can be rotated from the outside and lever no. So my picks for lever locks should be composed of a single part that will move the code part, and rotate mechanism. Therefore it should be durable, but at the same time thin to ensure mobility. You can use any sturdy pins that will be convenient to attach the handle to rotate and the barbs on the end for opening.

But do not forget that any illegal actions anyway will come the punishment. Before making the master key, think about its application. Even if the tool is used to open a private home, there may be unnecessary questions. Be careful! In our lives can happen. And better to be safe with if not, then at least the knowledge of how to make a lock pick.

Additionally, if you need some of the lock picks tools, you could purchase at Banggood, one of the wholesale platform to provide you the low prices. Such as, goso lock pick set, door lock pick set, etc.
