Q: The strength of a diode will be listed in microwatts (mW). The color of the diode will be determined by its wavelength (measured in nanometers, nm). A wavelength of 650 nm corresponds to a red laser, a wavelength of 405 nm corresponds to a blue laser, and  a green laser has a wavelength around 520 nm. Green lasers are the most expensive, followed by blue. Red is the cheapest. You can buy diodes online and sometimes at electronic supply stores. The diode costs can range anywhere from tens to thousands of dollars, depending on the laser you choose. If you aren't picky about the color, you can take apart an old DVD or Blu-Ray disk burner. There will be two diodes. Find the diode on the disk burning side. The one on the disk reading side is not strong enough to produce a burning laser. The diode will look like a small round light. It is likely encased in metal and will be positioned so that it can shine on the bottom of the DVD/Blu-Ray tray. Once you have located the disk burning diode, remove it from the DVD (or Blu-Ray) burner. You may have to remove small screws or cut the diode away from the rest of the burner. It is possible that the diode is encased in a metal casing. If this is the case, the casing can be left on the diode after you remove it.
A: Select a diode strength and color. Take apart an old DVD or Blu-Ray disk burner. Salvage the diode from the disk burner.

Q: The most successful printing entrepreneurs start a printing business by finding a niche in a specialized area, such as digital printing. Instead of trying to be all things to all people, success is more attainable by targeting a need and fulfilling it. One of the best examples of this strategy can be seen by the success of franchise sign printing businesses, which target budget-minded business owners who only need occasional signs and banners, which can be spotty (inconsistent demand) or loaded with competition. They do not attempt to offer anything but quick-turnaround signs and leave brochures and envelope printing to traditional offset printing businesses. Realize that the niche for color printing and the better quality grade of printing may be in a certain number of dots per inch (DPI), which can be very demanding and tricky to match. Remember, as a business owner, you will be responsible for the timely completion of jobs to your customer’s satisfaction. Caution: Any verbal or written agreement like You [the printer] know what looks right, so you can okay the proofs for color and quality is loaded with the danger of customer rejecting the finished product. For example, they may require:  Product match, excellent quality – very precise color, hue, and tone for high end products. Color match, excellent quality – usually precise Process Matching System (PMS Colors) by screen values (tones created by dot sizes) of the 4 process colors (cyan, magenta, process yellow, and black). Or just pleasing color, of medium quality – which is not so precisely matched. Caution: that means pleasing to the customer, not to you. Commercial quality printing is probably a cut above desktop publishing, done in your-office (above typical office printer, copier, or duplicator quality). It requires sharp line art and text – fineness of line work does not vary from page to page, screen color or halftone detail is consistent. Any choice of printing process (or brand of paper) shown on a quote to your customer is for them to choose. No, you can not substitute a more profitable method or material. Unless they agree in writing to a change, they can demand that it be redone at your expense -- if you did not follow written specifications precisely.
A: Find a niche within the printing industry. Familiarize yourself with the business standards. Be careful with your words.

Q: Click the Windows logo in the bottom-left corner of the screen. You can also just right-click Start if you want to select Device Manager from the advanced menu. Type device manager into Start, then click Device Manager at the top of the Start results. If you right-clicked Start, click Device Manager in the menu that appears. You'll find this in the "U" section near the bottom of the Device Manager window. Double-click the heading to do so. You should see several indented options appear below the "Universal Serial Bus controllers" heading. Skip this step if this heading is already expanded. The name of this option may vary depending on your computer, but it will usually have "USB 3.0" written next to it. It's a tab at the top of the Device Manager window. A drop-down menu will appear. This option is in the drop-down menu. Doing so disables the built-in USB adapter. While disabling the built-in USB adapter will remove most of the other USB items from below the "Universal Serial Bus controllers" heading, there may be one or more remaining USB options. Disable these by clicking an option, clicking Action, clicking Disable Device, and repeating until each USB option is disabled. Your computer's USB ports should no longer work. If you need to re-enable the USB ports, go back to Device Manager, select a USB option, click Action, click Enable Device, and repeat until your USB options have been restored.
A: Open Start . Open Device Manager. Scroll down to the "Universal Serial Bus controllers" heading. Expand the "Universal Serial Bus controllers" heading. Select the "Root Hub" or otherwise built-in USB option. Click Action. Click Disable Device. Disable any remaining USB options under the heading. Close Device Manager.

Q: Website optimization involves using the right keywords and headlines to show up at the beginning of online searches. This is an essential element when it comes to improving traffic to your website. Incorporating images and accurately labelling them will help you in this process. This process is often referred to as SEO, which stands for Search Engine Optimization. If you have optimized a website to show up under search terms for your business, include the same keywords alongside an accurate image descriptor to title your photo. This will ensure that users are linked to your page when searching for the images that correspond to the content on your website.  You can also use your URL keywords to keep it simple. If your URL title is “buy-our-stuff.html,” and you’re selling hats, label an image “buy-our-stuff-hat-1.jpeg.” If you’re using keywords to make your images show up more often on search engines but the descriptive titles of your images aren’t accurate, you’re harming your user’s experience. Alt tags are hidden text that are revealed in browsers used by the visually impaired. This text is read by search engines however, which makes it an excellent place to include keywords or search terms that you may not need to list publicly. Keep these tags accurate though—you don’t want to sacrifice visibility for accuracy. If there is important information that you want to include for your user but don’t want to include in your image tag, put it in a caption. Captions could include commentary or clarifying information about an image, and will bolster your image’s profile without bogging down the title.  Captions are the small little quotes or lines that go underneath an image—usually in a smaller font than the rest of your content. An example of a caption for a photograph of a president giving a speech could be, “The president speaking at a benefits concert before the opening act."
A:
Understand how optimizing your website informs searches. Copy headline and URL keywords to make accurate image labels. Include keywords in the image information and alt text. Use captions to provide additional information on your site.
