  • Sound Waves Visualized with a Chladni Plate and Colored Sand [Video]

    - by Jason Fitzpatrick
    This eye catching demonstration combines a Chladni Plate, four piles of colored sand, and a rubber mallet to great effect–watch as the plate vibrates pattern after pattern into the sand. A Chladni Plate, named after physicist Ernst Chladni, is a steel plate that vibrates when rubbed with a rubber ball-style mallet. Different size balls create different frequencies and each frequency creates a different pattern in the sand placed atop the plate. Watch the video above to see how rubber balls, large and small, change the patterns.

  • How to Transpose Rows and Columns in Excel 2013

    - by Lori Kaufman
    You’ve setup your worksheet with all your row and column headings and you’ve entered all your data. Then, you discover that it would look better if the rows were the columns and the columns were the rows. How do you accomplish this easily? There is an easy way to convert your rows to columns and vice versa using the Transpose feature in Excel. We’ll show you how. Select the cells containing the headings and data you want to transpose. Click Copy or press Ctrl + C. Click in a blank cell on the spreadsheet. This cell will be the top, left corner of the new table of data. Click the down arrow on the Paste button and select Paste Special from the drop-down menu. On the Paste Special dialog box, select the Transpose check box so there is a check mark in the box and click OK. The rows become the columns and the columns become the rows. The original set of data still exists. You can select those cells and delete the headings and data, if desired. Isn’t that a lot easier and faster than retyping all your data?

    - by Jason Fitzpatrick

  • 50 Years of LEDs: An Interview with Inventor Nick Holonyak [Video]

    - by Jason Fitzpatrick
    The man who powered on the first LED half a century ago is still around to talk about it; read on to watch an interview with LED inventor Nick Holonyak. The most fascinating thing about Holonyak’s journey to the invention of the LED was that he started off trying to build a laser and ended up inventing a super efficient light source: Holonyak got his PhD in 1954. In 1957, after a year at Bell Labs and a two year stint in the Army, he joined GE’s research lab in Syracuse, New York. GE was already exploring semiconductor applications and building the forerunners of modern diodes called thyristors and rectifiers. At a GE lab in Schenectady, the scientist Robert Hall was trying to build the first diode laser. Hall, Holonyak and others noticed that semiconductors emit radiation, including visible light, when electricity flows through them. Holonyak and Hall were trying to “turn them on,” and channel, focus and multiply the light. Hall was the first to succeed. He built the world’s first semiconductor laser. Without it, there would be no CD and DVD players today. “Nobody knew how to turn the semiconductor into the laser,” Holonyak says. “We arrived at the answer before anyone else.” But Hall’s laser emitted only invisible, infrared light. Holonyak spent more time in his lab, testing, cutting and polishing his hand-made semiconducting alloys. In the fall of 1962, he got first light. “People thought that alloys were rough and turgid and lumpy,” he says. “We knew damn well what happened and that we had a very powerful way of converting electrical current directly into light. We had the ultimate lamp.” How To Get a Better Wireless Signal and Reduce Wireless Network Interference How To Troubleshoot Internet Connection Problems 7 Ways To Free Up Hard Disk Space On Windows

  • How to Use the Signature Editor in Outlook 2013

    - by Lori Kaufman
    The Signature Editor in Outlook 2013 allows you to create a custom signature from text, graphics, or business cards. We will show you how to use the various features of the Signature Editor to customize your signatures. To open the Signature Editor, click the File tab and select Options on the left side of the Account Information screen. Then, click Mail on the left side of the Options dialog box and click the Signatures button. For more details, refer to one of the articles mentioned above. Changing the font for your signature is pretty self-explanatory. Select the text for which you want to change the font and select the desired font from the drop-down list. You can also set the justification (left, center, right) for each line of text separately. The drop-down list that reads Automatic by default allows you to change the color of the selected text. Click OK to accept your changes and close the Signatures and Stationery dialog box. To see your signature in an email, click Mail on the Navigation Bar. Click New Email on the Home tab. The Message window displays and your default signature is inserted into the body of the email. NOTE: You shouldn’t use fonts that are not common in your signatures. In order for the recipient to see your signature as you intended, the font you choose also needs to be installed on the recipient’s computer. If the font is not installed, the recipient would see a different font, the wrong characters, or even placeholder characters, which are empty square boxes. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can save it as a draft if you want, but it’s not necessary. If you decide to use a font that is not common, a better way to do so would be to create a signature as an image, or logo. Create your image or logo in an image editing program making it the exact size you want to use in your signature. Save the image in a file size as small as possible. The .jpg format works well for pictures, the .png format works well for detailed graphics, and the .gif format works well for simple graphics. The .gif format generally produces the smallest files. To insert an image in your signature, open the Signatures and Stationery dialog box again. Either delete the text currently in the editor, if any, or create a new signature. Then, click the image button on the editor’s toolbar. On the Insert Picture dialog box, navigate to the location of your image, select the file, and click Insert. If you want to insert an image from the web, you must enter the full URL for the image in the File name edit box (instead of the local image filename). For example, http://www.somedomain.com/images/signaturepic.gif. If you want to link to the image at the specified URL, you must also select Link to File from the Insert drop-down list to maintain the URL reference. The image is inserted into the Edit signature box. Click OK to accept your changes and close the Signatures and Stationery dialog box. Create a new email message again. You’ll notice the image you inserted into the signature displays in the body of the message. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You may want to put a link to a webpage or an email link in your signature. To do this, open the Signatures and Stationery dialog box again. Enter the text to display for the link, highlight the text, and click the Hyperlink button on the editor’s toolbar. On the Insert Hyperlink dialog box, select the type of link from the list on the left and enter the webpage, email, or other type of address in the Address edit box. You can change the text that will display in the signature for the link in the Text to display edit box. Click OK to accept your changes and close the dialog box. The link displays in the editor with the default blue, underlined text. Click OK to accept your changes and close the Signatures and Stationery dialog box. Here’s an example of an email message with a link in the signature. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your contact information into your signature as a Business Card. To do so, click Business Card on the editor’s toolbar. On the Insert Business Card dialog box, select the contact you want to insert as a Business Card. Select a size for the Business Card image from the Size drop-down list. Click OK. The Business Card image displays in the Signature Editor. Click OK to accept your changes and close the Signatures and Stationery dialog box. When you insert a Business Card into your signature, the Business Card image displays in the body of the email message and a .vcf file containing your contact information is attached to the email. This .vcf file can be imported into programs like Outlook that support this format. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your Business Card into your signature without the image or without the .vcf file attached. If you want to provide recipients your contact info in a .vcf file, but don’t want to attach it to every email, you can upload the .vcf file to a location on the internet and add a link to the file, such as “Get my vCard,” in your signature. NOTE: If you want to edit your business card, such as applying a different template to it, you must select a different View other than People for your Contacts folder so you can open the full contact editing window.

  • How to Disable Home Folder Encryption After Installing Ubuntu

    - by Chris Hoffman
    Ubuntu offers to encrypt your home directory during installation. The encryption has some drawbacks – there’s a performance penalty and recovering your files is more difficult. If you change your mind later, you can remove the encryption without reinstalling Ubuntu. The process of removing the encryption involves creating a backup copy of your home directory without encryption, deleting the existing home directory, removing the encryption utilities, and moving the unencrypted copy back into place.

  • The Strange History of the Honeywell Kitchen Computer

    - by Jason Fitzpatrick
    In 1969 the Honeywell corporation released a $10,000 kitchen computer that weighed 100 pounds, was as big as a table, and required advanced programming skills to use. Shockingly, they failed to sell a single one. Read on to be dumbfounded by how ahead of (and out of touch with) its time the Honeywell Kitchen Computer was. Wired delves into the history of the device, including how difficult it was to use: Now try to imagine all that in late 1960s kitchen. A full H316 system wouldn’t have fit in most kitchens, says design historian Paul Atkinson of Britain’s Sheffield Halam University. Plus, it would have looked entirely out of place. The thought that an average person, like a housewife, could have used it to streamline chores like cooking or bookkeeping was ridiculous, even if she aced the two-week programming course included in the $10,600 price tag. If the lady of the house wanted to build her family’s dinner around broccoli, she’d have to code in the green veggie as 0001101000. The kitchen computer would then suggest foods to pair with broccoli from its database by “speaking” its recommendations as a series of flashing lights. Think of a primitive version of KITT, without the sexy voice. Hit up the link below for the full article.

  • Hack Your Lights for Remote Control

    - by Jason Fitzpatrick
    This clever hack combines a modified wall switch with unused buttons on a universal remote to create one-touch wireless control of the lighting in a media room. Andrew, the tinker behind this home theater hack, writes: I really liked the idea of controlling my “Home Theater” lights with a remote (TV or other), this would save me the exhausting task of heaving myself off the couch to turn the lights on or off. I found one of my remotes has a spare power button, its one of those stupid “universal” remotes that comes with DVD players or TVs but only work if you have all the same brand equipment, I don’t so this made a good option for a light switch.

    - by Chris Hoffman
    The Windows Event Viewer shows a log of application and system messages – errors, information messages, and warnings. Scammers have used the Event Viewer to deceive people – event a properly functioning system will have error messages here. In one infamous scam, a person claiming to be from Microsoft phones someone up and instructs them to open the Event Viewer. The person is sure to see error messages here, and the scammer will ask for the person’s credit card number to fix them. As a rule of thumb, you can generally ignore all of the errors and warnings that appear in the Event Viewer – assuming your computer is working properly.

  • DIY Door Lock Grants Access via RFID

    - by Jason Fitzpatrick
    If you’re looking to lighten the load on your pocket and banish the jingling of keys, this RFID-key hack makes your front door keycard accessible–and even supports groups and user privileges. Steve, a DIYer and Hack A Day reader, was looking for a solution to a simple problem: he wanted to easily give his friends access to his home without having to copy lots of keys and bulk up their key rings. Since all his friends already carried a Boston public transit RFID card the least intrusive solution was to hack his front door to support RFID cards. His Arduino-based solution can store up to 50 RFID card identifiers, supports group-based access, and thanks to a little laser cutting and stain the project enclosure blends in with the Victorian styling of his home’s facade. Hit up the link below to see his code–for a closer look at the actual enclosure check out this photo gallery. RFID Front Door Lock [via Hack A Day] HTG Explains: What is DNS?

  • Read All The Books from Skyrim on Your Ebook Reader

    - by Jason Fitzpatrick
    If you’re a fan of the wildly popular RPG game Skyrim, you’ve undoubtedly discovered the books sprinkled throughout the Empire. This collection brings them all together for out-of-game reading. Blogger and Skyrim fan Capaneus enjoyed reading the in-game books so much (found on the shelves of homes and otherwise scattered throughout the virtual world) that he did a little digging in the game files to turn up the source of the books. It turns out he didn’t have to dig too deeply, the files are stored as text documents (and if you have a copy of the game installed right now you could easily open them up yourself). He took those text files and carefully formatted them as MOBI and EPUB files, well suited for use on an ebook reader or tablet. Hit up the link below to grab a copy for your own perusal. While we can’t see this lasting long in the age of copyright enforcement and litigation we’d like to think the company behind Skyrim will see the utility of sharing the books (existing Skyrim owners will enjoy it and the curious will likely be inspired to buy the game).
