In one sentence, describe what the following article is about: At minimum, you should wear safety goggles and heat-resistant, fire-resistant gloves. Also note that you will need to handle the stainless steel object with another device, like tongs or a vice. Everything you use should be both fire-resistant and heat-resistant to prevent accidental burns. You'll need to prepare enough coffee grounds to cover all sides of the stainless steel object you wish to antique. If you've recently made a pot of coffee, you can use the spent grounds from that. Otherwise, pour enough warm to hot water over a fresh batch of grounds and give the grounds a few minutes to absorb the moisture For small, narrow objects like screws, you can fill a small cup with your prepared grounds. For larger objects, coat the bottom of a shallow tray with the grounds, instead. Hold the metal object with tongs or a vice, then pass the flame of a lighter over the entire length of the object, heating it thoroughly. Continue rotating and passing the flame over the stainless steel object until the metal begins to darken in color. For larger objects or a more controlled flame, consider using a propane tank with a lighter attachment instead of a handheld lighter. The stainless steel will reach temperatures just beneath 500 degrees Fahrenheit (260 degrees Celsius), so you need to work very carefully to prevent accidental burns. As soon as the steel object darkens, quickly dip the heated portion into the prepared coffee grounds. Hold it in the grounds for 15 to 30 seconds. The water in the coffee grounds should quickly cool off the metal. Theoretically, the steel should be safe to touch once you remove it from the grounds, but you should still proceed with caution. In addition to cooling off the metal, the coffee should dye the stainless steel, giving it the appearance of antiqued metal. If you want to dye the steel even darker, reheat it and submerge it into the coffee grounds again. You should be able repeat the process several times without damaging the metal. If you only want to dye one side or area darker, focus the heat on that area and only apply the coffee grounds to that spot. When you're satisfied with the results, you can quickly polish the steel object by vigorously rubbing it with a soft cloth. Wait until the object is cool enough to touch before polishing it. Polishing the piece should buff away coffee granules and some of the dark dye. It should also make the steel a little shinier. After you dye and polish the piece to your liking, the project is complete. The results should last indefinitely.
Summary: Wear the appropriate safety gear. Fill a container with warm, moist coffee grounds. Heat the steel using a lighter. Bury the steel in the coffee grounds. Repeat as needed. Polish as desired.

In one sentence, describe what the following article is about: You may have noticed that there are a wide variety of barcodes, some appearing like thin lines and others, like QR codes, which are more blocky in appearance. These barcode types are called symbologies, some of which include: Plessey: Used for catalogs, store shelves, inventory UPC: Used for North America retail EAN-UCC: Used for international retail Codabar: Used for libraries, blood banks, airbills Code 39: Used for various purposes Code 128: Used for various purposes Code 11: Used for telephones Code 16K: 1D version of Code 128. QR Code: Public domain code from Nippon Denso ID Systems. Has the ability to encode Japanese Kanji and Kana characters. The information you want contained in your barcode will need to be translated to a suitable barcode format, like an alphanumeric string, for it to be properly read by scanners. You should have a general format in mind for how you will structure all barcodes for your particular purpose. Many different kinds of information can be included in your barcode, but generally this information pertains to: identification, tracking, and inventory. Consistent formatting will help make the translated information easier to read, and will make human processing of barcode information more efficient. "Alphanumeric" refers to a system that uses both letters and numbers. Now that you have your data properly organized, do an online search for a "String builder" for the barcode symbology you will be using. This will give you the converted text that you will need to use with a barcode font. For example, you might search, "barcode string builder code 128." Some symbologies may use other inputs than simple alphanumeric. Do an online search of your chosen symbology to find how to convert your data to a suitable barcode format. To have the text you've converted to show up properly as a barcode, you'll need to input your barcode string into your Word document in the font for your symbology. There are many online sources for fonts, some free and some for pay, which you can find by searching your symbology (e.g. Code 39 font). Always exercise caution when downloading anything from the Internet. There is always the risk that you may get a virus or some other kind of malware. Cut and paste your converted barcode string into your word document. Highlight this text, and then change the font to the appropriate barcode font and your barcode should appear.
Summary:
Choose your barcode symbology. Choose your data to convert. Convert your data into proper barcode format with an online service. Download the right font for your barcode. Convert your barcode string into your word document.
