Machine CNC (computer numerical control) is set with an intelligent unit that reads the program and monitors the drive hardware. Simply put, after the introduction of the operator program code, the computer controls all processes. By type units are divided into:

Combined options.

Models for use with thread.

Modification, not only the processing timber but also plastic, stone, metal.

With the advent of production equipment CNC wood processing, including the fabrication of any carved elements much easier, increasing the accuracy and speed of work, and the cost of manual processing - order of magnitude lower.

Woodworking DIY CNC Slide Table is often used for pass-through recess of the workpiece. For example, milled MDF very easily, even the entire height of the items in a single milling. Other materials, depending on the density and other characteristics, several attempts require treatment. Made on equipment such products have high accuracy and quality of processing (for example, in the manufacture of wood flooring). The disadvantage is the time that at high speeds the place of cutting tending scorching light. Furthermore, with NC processing unit is difficult to obtain sharp boundaries engraving lines (rounding remain equal to the radius of the cutter).

Original JYE-Tech DS0150 Digital Oscilloscope DIY Kit

As we can see, oscilloscope has a rarely high accuracy, which is unlike multimeter, but allowing us to see the processes in the dynamics. Earlier oscilloscopes consisted of vacuum-tube which then replaced by the transistor, but the result is still displayed on the CRT screen. Eventually, they were replaced by the digital counterparts, smaller, lighter and more convenient. However, have you ever tried to develop a homemade oscilloscope by yourselves?

The collecting is certainly easy and even a schoolboy can done it on his own hands. The most important thing you have to do is choosing a decent DIY Digital Oscilloscope Kit. In this article, I would like to recommend the JYE Tech DS0150, of which features are as following.

1. DSO Shell has similar bandwidth as DSO138 though it contains significant improvements in structure, mechanical, and operation.
2. Display and MCU are now mounted on the same board (mainboard), avoiding using inter-board pin-headers. Users’ feedback from DSO138 has shown that soldering on the pin-headers is often problematic for many beginners. Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. Without the analog portion the mainboard is actually a general purpose control board that can be used in many other applications. The mainboard is fully installed (except a few through-hold components) and factory tested before packing.
3. This DIY Digital Oscilloscope Kit comes with full enclosure. The front panel and top/bottom brackets are flexible for easy user modification.
4. Rotary encoder has been added. It makes parameter adjustment much quicker and easier.
5. The sensitivity of DSO Shell has been extended in both directions and is higher and wider than DSO138. It reaches 5mV/div --- 20V/div while DSO138 is only 10mV/div --- 5V/div.
6. DSO Shell runs on 9V power supply. Users need to prepare their own power supply since it is not included in the kits. The power jack on the mainboard is 5.5mm/2.1mm DC plug. Alternative 2-pin connector (0.1" pitch) is also provided for convenience to connect to different power sources.

Types of Nuts and Their Characteristics

Nut - a kind of threaded fasteners through which you can capture good fasteners. Modern nut IS a specialized part, which is produced with a specific internal thread. Nut is a fastening element, which is the perfect complement to the fastener screw unit. Today, there are many types of fasteners: castellated, low flange, square, etc. Production of nuts on the corresponding factories made from nonferrous metal, stainless, alloy or carbon steel.

Over the years, the nut is used as a constituent element of the fastening system in any industrial sector. Today there are many different kinds of nuts, differing among themselves, thread size, purpose, form. To better understand the challenges, opportunities nut consider in more detail the main types of hardware.

1. Hex. This type of fastening elements (e.g. plastic standoffs nut) is quite common and can be used in any industrial sector. A characteristic feature of the "hex" is the presence of a chamfer (not required). For comfortable work with hardware specialists use a wrench, the size of which is selected according to the size of the nut.
2. Crown. A characteristic feature is the presence of the fastener on one side end of a few small grooves, whose number is always even.  o work with such kind of nuts should be used, not only a screw or bolt, but the pin. It helps to fix the position of the nut without the possibility of spontaneously unwind. Application: Connection of elements with high physical, vibratory loads.
3. Cap. It is used for protection, masking fastening. The outer shape is made on a "hex". The greatest spread of the cap nut is received in the factories for the manufacture of furniture, business centers (when necessary to prevent mechanical damage to the protruding end of the fixture).
4. Lamb. A characteristic feature of 'lamb' is the nuts geometric shape: the original projections resemble ears blades. Using the wing nut is done by hand, without the use of additional tools. The unique shape of the nut makes it possible to fix the elements together tightly as possible. It can be used as a decorative element, the coupling.

BTW, you can select the nuts at Banggood. Besides, you can easily get other electrical accessories (e.g. hex shank adapter) there with high quality and reasonable prices.

Quick Splice Connector for Medical Institutions

Medical sockets are often quick-connect terminal, in addition to the connectors can be attached filter attachment. Sockets are integrated in the medical gas distribution and console, medical monitors, maintaining vital functions of the system of transport boxes into transport ventilators, cryogenic gasifiers, filtering installations, are installed on the health of the ramp. Female wire connector sockets support the functioning of the chemical and biological defense systems.

According to the rules of designing health care facilities:

"To connect portable medical equipment in wards (except for children's and psychiatric wards) provides for a power outlet with a grounding pin for every two beds. To connect a mobile X-ray machine in the corridors of ward offices, installed three-pole sockets with grounding type RSH-30 on one piece into two chambers). In the children's and psychiatric sockets with earth contact for connecting portable medical equipment, installed in the corridors at the entrances to the Chamber for one socket on the ward (in the pediatric wards of 1.8 m in psychiatric wards - in special compartments with lockable doors) . All sockets for connecting portable medical devices should be with cylinder contacts. "

The minimum distance from the switches, sockets and electrical elements to the pipeline should be at least 0.5 m. Connect the power outlet in medical rooms of group 2nd medical IT system. For each location the treatment of patients, such as a pillow beds, subject to the following rules for the installation of power sockets:

- Should have at least two outlets powered by separate lines.

- Personal protection against overcurrent for each outlet should be provided.

If other systems (TN-S), the outlet connected to the medical system in terms of IT medical facilities must have the design, which would exclude their use in another system, or clear, strong labeling tied to a particular system.
