Photography today offers many opportunities for creativity and experimentation. The many types of cameras and lenses available invite numerous variations on photo styles and techniques. But a few tricks have been around since long before the digital camera and image came on the scene. Creating a soft-frame or fuzzy, foggy look can be done either directly on a camera lens or you can do it now with graphics programs like Photoshop after the images are taken.
Fog machines use heat to vaporize a special mixture of water and glycol, creating a fog that can fill a room very quickly. Because the fog is warm, it tends to rise and dissipate quickly. In order to make the fog stay low against the ground, it must be cooled. You can do this with a homemade chiller built out of an ice chest.
Fog usually pervades a location and appears to have no visible beginning or end. By contrast, a fog bank is a build-up of fog into a visible mass with distinct edges observable from a distance by the human eye. Fog banks are usually found in coastal areas, near lakes and out at sea.
Fog machines use a special fluid to create a fog. The fluid is stored in a reservoir and pumped onto a hot plate, which atomizes the fluid and sprays it out as a haze. If your fog machine has run out of fluid, you can make your own refills as an alternative to purchasing more. You may have to do some experimentation to find a mixture that delivers a fog density you find satisfactory. But concocting the perfect fog makes the effort worthwhile.
Sometimes it is necessary to measure low-pressure gas, such as when you're working with propane or natural gas or when tuning carburetors. Many companies are willing to sell you a fancy and expensive digital or analog gauge calibrated in inches of water column (in. WC). However, you don't need expensive equipment to take the measurement. You can build an inexpensive and accurate gauge called a water manometer from materials found in any hardware store, using tools that most people have around the home.
Mechanical oil pressure gauges are simple devices that read pressure directly from the oil. Oil pressure acts on a diaphragm or bellows which moves slightly and in direct proportion to the pressure it is experiencing. This motion moves a needle on a dial via a mechanical link. When installing the device, you must be careful that there is no residual pressure in the line you are tapping and wear protective gloves if the oil is at high temperatures. Oil is not corrosive, so no special materials are required. Following installation, you must calibrate the gauge to ensure accuracy.
A Magnehelic differential pressure gauge shows the relative pressure difference between two points. If both points have equal air pressure, the gauge reads zero. Such gauges are used in manufacturing, HVAC systems, painting booths, and venting, as both safety devices and a visual confirmation that the device is operating properly. Using a differential pressure gauge requires installing it properly and running air hoses from both points of the reading.
Water vapor can be used to simulate smoke or make an artificial fog. There are several ways you can produce this effect, but the simplest involves dry ice, which is an item you can purchase at many supermarkets and convenience stores. Just call ahead to make sure your local supermarket actually stocks dry ice, then make sure you have an ice chest or cooler to carry it. Make sure the cooler isn't airtight, and don't leave it inside a car with the windows closed (the carbon dioxide concentration could build up in the vehicle). Above all, don't try to handle…

Fog is formed when a warm, wet air front collides with a cold air front. As the two fronts mix together, the air in the warm front quickly cools. Since cool air cannot hold as much water as warm air can, the water vapor present in the air condenses to form the tiny water droplets that make up fog. You can easily demonstrate this effect and create fog using a water bottle.
There are two common ways to make fog for use at a Halloween party or during a laser light show. Both methods are simple, but the difficulty is procuring the items used to make the fog. The thickness of the fog may be changed by varying the proportions of the mixed ingredients or by modifying the delivery systems.
Smoke machines are used for many different applications. They are commonly used in nightclubs, on the stage and during rock concerts. These machines use a fluid that when heated produces smoke. The main ingredient in the fluid is food-grade glycol, which is approved for food, beverage and medical uses. The glycol produces a heavy, fog-like smoke.
Fog and smoke are desired effects for a variety of settings, including theater productions, plays, photography and film shoots. Traditional fog machines are a trusted way to create these effects, although they may not be feasible for all situations. For example, fog machines cannot be used in settings without electrical access, some people are sensitive to the fog produced by the machines, and theater productions often require smoke effects on stage where the bulky machine would be a distraction. A variety of alternative techniques exist to create smoke in settings with special circumstances.
Nothing enhances a haunted house or theater set like a little fog. Or perhaps you are producing an independent horror film and need to produce some spooky mist on the cheap. There are two different methods that professionals use to make fog and you can use without breaking the bank.
A fog machine makes a dynamic addition to any Halloween party. The only problem is that fog machines use heat to build up the vapor from the dry ice, which also makes the fog go into the air and evaporate. Build or buy a fog chiller to keep the fog low to the ground, making a rolling effect. A trip to your local retail and home improvement store is all you need to create a simple fog chiller for your next party.
Building a fog machine is possible using several different methods. Some are fairly technical, requiring compressors and mineral oil, for example, but the simplest fog machine is one that virtually anyone can make at home with little more than a 5-gallon plastic bucket, some hot tap water and possibly a small fan.
Fog machines are wonderful to use in plays, performances, nightclubs or even just for fun at home. A lot of times, the average fog juices available for purchase don't produce a fog that is thick enough for some people's tastes. If you make your own fog juice, however, the results are phenomenal. Your fog machine will not only produce thicker, more high quality fog, but making the juice is extremely cost friendly and can save you lots of money.
There are two basic types of fog machines: those that use dry ice and those that use a chemical fogging fluid or "fog juice." Dry ice machines have the advantage that the fog it makes is already cool and will fall rather than rise, creating an often desirable effect. Fluid foggers are simple to use, economical and create fog that dissipates less quickly than dry ice fog, making them a popular choice for consumer use. A disadvantage of fluid foggers is that the units, and the fog they make, become warm, causing the mist to rise. To create low-gravity effects…
The MIT Department of Mechanical Engineering defines a lathe as a machine that spins a metal or wooden form against a precisely moving cutting tool to create new shapes in the form, ranging from outer contours to threaded holes. While American Machine Tools mentions a few broad categories of lathe types, it adds that all lathes operate on the same basic principles using the same basic components to shape a variety of devices, from screw heads to crankshafts.
A mortise machine is woodworking power tool that performs one specialized task: it bores square-sided holes to form the mortise for a mortise and tenon joint. The mortiser is a stout drill press with a long arm that offers the leverage needed to cleanly drill and cut the fibers in a hardwood component. The cut is made by a combination of a drill bit and a square chisel that work in tandem to form the hole.
Whether you're hosting a spooky Halloween celebration, or you just want to provide an extra level of exciting atmosphere at a dinner party, making a homemade fog machine is pretty easy. You need just a few simple tools and a little dry ice to create a mood which is just downright scary.
Building a model of a volcano is a fun way to learn about the earth's geology, and making it erupt makes for even more fun. But the traditional eruption technique, mixing vinegar and baking soda, makes a quick eruption that's over in seconds. Adding a fog machine to a volcano to simulate steam coming from the crater makes a much more realistic looking volcano and can last for hours.
From home hobbyists to large corporations, vacuum forming has been used as an efficient, economical way to make plastic parts. Manufacturers vacuum-form plastic trays, packaging, signs and thousands of other items. The basic machine is a simple system consisting of a clamp frame, heater and vacuum system which can be used with countless different molds. The mold determines the shape of the finished part and can be reused for many years.
The Cuttlebug by Provo Craft is a versatile die-cut and embossing machine. The beauty of the Cuttlebug is the inexpensive embossing folders and dies, and the ability to use dies from several other manufacturers.
The Cricut Personal Electronic Cutter Machine, manufactured by Provo Craft, allows users to make die-cut shapes and letters using paper, card stock, vinyl and fabric for use in making cards, scrapbooking and other paper crafts.
Mortising machines are an invaluable tool for woodworkers who strive for accurate mortises or who use mortise joinery extensively in their work. The machines are moderately priced and made by a number of respected woodworking machine manufacturers.
Creating your own fog machine can add a nice effect to your Halloween party or event. Depending on how much fog you are looking to produce, you will need to adjust your measurements of ingredients. However, this is a relatively easy project to tackle and make your event stand out.
Fog machines can be found in many places, including dance clubs, theaters and haunted houses. Most people who have fog machines typically only use them for Halloween. The liquid solution that produces the fog, often referred to as "fog juice," can get expensive, especially if you use your fog machine frequently. But you can make your own fog solution for a fraction of the price.
Liquid pressure gauges are used in a variety of applications and settings. Industrial environments where coatings and sealants are applied on a regular basis rely on a gauge's readings to ensure safety guidelines are being met, and application amounts are per specifications. Gauges are manufactured to meet certain guidelines, as put forth by the American National Standards Institute, or ANSI, and are designed to different accuracy readings, depending on the application type. Liquid pressure gauges can provide needed information when a machine malfunctions, allowing operators to attend to the problem before more serious problems develop. A second type of pressure…
