The most familiar numbers arе thе natural numbers оr counting numbers: one, two, three, and ѕo on. Traditionally, the sequence of natural numbers started with 1 (0 wаѕ nоt еven considered а number for the Ancient Greeks.)

The most familiar numbers are the natural numbers or counting numbers: one, two, three, and so on. Traditionally, the sequence of natural numbers started with 1 (0 was not even considered a number for the Ancient Greeks.) However, in the 19th century, set theorists and other mathematicians started including 0 (cardinality of the empty set, i.e. 0 elements, where 0 is thus the smallest cardinal number) in the set of natural numbers.[citation needed] Today, different mathematicians use the term to describe both sets, including zero or not. The mathematical symbol for the set of all natural numbers is N, also written  \mathbb{N}.
In the base ten numeral system, in almost universal use today for mathematical operations, the symbols for natural numbers are written using ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In this base ten system, the rightmost digit of a natural number has a place value of one, and every other digit has a place value ten times that of the place value of the digit to its right.
In set theory, which is capable of acting as an axiomatic foundation for modern mathematics,[2] natural numbers can be represented by classes of equivalent sets. For instance, the number 3 can be represented as the class of all sets that have exactly three elements. Alternatively, in Peano Arithmetic, the number 3 is represented as sss0, where s is the "successor" function (i.e., 3 is the third successor of 0). Many different representations are possible; all that is needed to formally represent 3 is to inscribe a certain symbol or pattern of symbols three times.

Bosch Router Bits

Typically renowned in the woodworking world as above average bits, Bosch bits boast precision cutting, extended durability and sharp edges.

These bits are available in either solid carbide, carbide tipped and steel variations depending on the users preference and the project at hand.

The patented micro grain carbide keeps the cutting edge sharp for up to 30-percent longer than standard micro grains, meaning you spend less time replacing bits and more time working. Bosch makes sure that you have the correct router bit no matter what the material is or project you have undertaken.

Bosch router bits work with wood, acrylic and MDF to name a few materials. With 500 options to choose from, you can rest assured you will find the one you need. Noted for their longer shanks, Bosch router bits allow you to utilize the entire length of the bit.

Not only does this allow for a more even wear on the bit, but the quality of the cut is improved as well.

For those who are just beginning to get into woodworking, it might be worth taking a look at the Bosch Multi-Construction Bit. This bit is geared towards working with wood, masonry, ceramic, plastic and metal. One could say it is a Jack of all trades without loosing the high quality that Bosch is known for.

If you are going to be doing a lot of work with one material in particular, then it is advisable to get a bit specific to that media. Bosch Multi-Construction Bits can be used with many rotary techniques and have a prolonged bit life, unlike other multi-construction bits that tend to wear and degrade with use.

Bosch router bits can be bought individually or in sets, depending on your rotary needs. Individual start around $15 and go up, while sets run about $100-200 depending on where you shop and how many bits in a set you purchase.

Bosch router bits are available in home improvement stores like Lowes and Home Depot, as well as online sites. Often times there are better prices online, but stores allow you to purchase and use the bit right away.

CNC Wood Router

A CNC wood router is a Numerical control tool that creates objects from wood. Parts of a project can be made and then assembled using a router to produce a complete project.

The CNC router works like a printer. Work is composed on a computer and then the design or drawing is sent to the CNC router for the hard copy. This outputs a 3-dimensional copy of the work. The CNC router uses a cutting tool instead of an ink jet.

The cutting tool is generally a router but other cutters can be used as well.

The CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control. CNC stands for computer numerically controlled cutting tool. This gives the computer a printer like ability to drive a CNC machine to make parts.

For engraving and general purpose cutting all that is needed is some material to engrave or cut on and an engraving or cutting tool bit.

A file of a picture or part has to be converted to g-code. Clamp the work piece down and then use the driver program to zero the CNC and run the g-code file. This will command the CNC to make the desired parts for you, quickly and accurately. Use it for all kinds of projects to make PCBs, gears, molds, etc.

The CNC Router is great for hobbies, engineering prototyping, product development, art, robotic education, and production work.

How it works

A CNC wood router uses CNC (computer numerical control) and is similar to a metal CNC mill with the following differences:

The wood router typically spins faster with a range of 13,000 to 24,000 RPM

Low end hobby grade machines typically uses smaller tools typical shank size 20 mm or at most 25 mm. Professional quality machines frequently use surface facing tools up to 3" in diameter or more, and spindle power exceeding 15 horsepower. Machines capable of routing heavy material at many hundreds of inches per minute are common.

Some machines use smaller toolholders MK2 (Morse taper #2 - on older machines), ISO-30, HSK-63 or the tools just get held in a collet tool holder affixed directly to the spindle nose. ISO-30 and HSK-63 are rapid-change toolholding systems. HSK-63 has begun to supplant the ISO-30 as the rapid change standard in recent years.

A wood router is controlled in the same way as a metal mill, but there is a lot of CAM and CAD software like Artcam, Mastercam, Bobcad, and Featurecam specifically for wood routers.

Wood with different grain must be approached with unique strategies, and wood CAM software is less likely to need to have hog-out strategies than the metal ones. Wood routers are frequently used to machine other soft materials such as plastics at high speed.

Typical three-axis CNC wood routers are generally much bigger than their metal shop counterparts. 5' x 5', 4' x 8', and 5' x 10' are typical bed sizes for wood routers. But can be built to accommodate very large sizes up to, but not limited to 12' x 100'. Most table routers use a three motor drive system (xyz) utilizing either servo or stepper motors that drive the router motor via a gantry system. The gantry system isolates the XYZ movement in the top part of the machine with a stationary table holding the workpiece. Many CNC metal mills have the cutter motor moving on the Z axis, and a table which moves in X and Y for added stability.

Many wood routers can run at machining speeds of 25 metres/min (linear) or faster with a few machines such as the Anderson capable of 40 metres/min, Onsrud capable of 86 metres/min.

Router Manager Download

In a relatively large local area network, there are usually multiple regular routers, wireless routers, wireless APs and switches. After a period of continuous running, there could be slowing down of network speed or even no-response failures. These require restart of the routers and switches. Unfortunately, most routers and switches cannot restart at a specific time, so we have to manually restart these network devices periodically.Grab A Copy Click here

If you have a server in the local area network that runs continuously for a long time, or a machine that can boot at a specific time, you can be freed from the cumbersome work. Router Manager is a router utility that can restart local/remote routers or switches at specific times and reduce the probabilities of network failures, and therefore, save you a lot of time and energy.

The router manager is the component of a Windows NT/Windows 2000 router that starts and manages the different routing components. The components include routing protocols, the routing table manager, and the multicast group manager.Grab A Copy Click here

Wireless CCTV - I Cannot Contact My Camera, Part 1

Wireless CCTV, as it is known, is becoming widely used in homes, holiday homes and businesses. It is CCTV over the internet, the digital replacement for those old analogue CCTV cameras, and enables you to see your property, live, from anywhere. I always advise home users to buy a fully-configured system that just plugs in, to keep things simple, but some people prefer to go their own way, and one of the common problems that the DIY beginner hits is that moment when he tries to log in over the internet to see the treasured home, and sees nothing! This article is the first of two in a series that explains some of the common causes of this problem and how to overcome them.

Now, we're going to start with the simple stuff and then work our way to the more technical. Firstly, you or someone near the camera should check the power. I have lost count of the number of times that customers have phoned to tell us that the camera is "broken" or "fried" or "dead". We always ask "Exactly what lights do you see at the back of the camera?" only to be told "Ah, yes, erm, it appears to be working now"! So check the obvious thing first. Still not working? The next thing to check is power at the router; again you should see at least some lights. If all is well, take a more detailed look at the lights on the router. Is the broadband light lit? (You may need to check the manual to see which light this is.)

The next checks are done through the web browser on your laptop or PC - and this is where things get more technical. If you are far away from the property where the camera is located, these checks may be your only option. The first thing to do is to see if you can log into the administration pages of the router over the internet, in other words, see if you can reach the network in the property where the camera is. (If your router has not been set to allow remote administration, you will be stuck, and should set this up next time you are at home!) You will need to know the internet or WAN IP address of your broadband connection, or the domain name if you use a dynamic domain name service such as dyndns.

Don't confuse the internet or WAN IP address with the internal or LAN one - here we are NOT looking for an address like 192.168.1.1. Remember that the address of your router, depending on the model and configuration, may end in a port number such as 8080. If you don't know the address of your camera and you're away from the property, you are stuck. Assuming you have the address, you will also need the admin user name and password for the router. If can log into the router's administration pages, this means that the broadband line is working and the home network is too. If you can't get this far, there could be a problem with the broadband line or the router, but you can only tell which by checking the lights on the router, which is obviously not possible if nobody is near it. You could always try to call the helpline of the broadband supplier if you are desperate and unable to get back to the property for a while, but getting them to test the line is not a trivial task and it may cost money if they find out there was no fault.

Assuming you have connected to the router, next you need to check that the wireless CCTV camera is talking to the network. Router models vary, but look for the wireless section, and somewhere you should find a list of "clients" currently connected to the network. If there is a refresh button on this page, hit it. The camera's name should be in the list. If it is not, then the camera is not talking to the network. In this scenario, the camera will need to be physically switched off and on again, and possibly also the router too. If you are away from the property and there is nobody else there, again you are stuck.

The next article in this series will help you if your camera is connected to the router but you still cannot see its picture.
