We know when to watch out for malicious links and tread lightly during those times. But this hack will still bite even the most cautions of link followers. It’s a <a href="http://bilaw.al/2013/03/17/hacking-the-a-tag-in-100-characters.html">hack that changes where a link is sending you <em><b>after</b></em><b> </b>you click on it</a>.</p> <p>The concept is driven home right away by a link in the post which lists PayPal as the target when you hover over it with your mouse. Clicking on it will give you a warning that it could have been a malicious page you were redirected to. Of course the address line of the page shows that you were sent somewhere else, but it’s still an interesting issue. The hack is accomplished with just a few lines of JavaScript. In fact, the original example was 100 characters but a revision boils that down to just 67.</p> <p>So who’s vulnerable to this kind of thing? It sounds like everyone that’s not using the Opera browser, which has been patched against the exploit. There are also some updates at the bottom of the post which mention that Firefox has been notified about it and Chrome is working on a patch.</p> <p>[via <a href="http://www.reddit.com/r/programming/comments/1ao06m/hacking_the_a_tag_in_100_characters/">Reddit</a>]</p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/security-hacks/" title="View all posts in security hacks" rel="category tag">security hacks</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/html/" rel="tag">html</a>, <a href="http://hackaday.com/tag/javascript/" rel="tag">javascript</a>, <a href="http://hackaday.com/tag/redirect/" rel="tag">redirect</a></span> </div> </div><!-- end .postclass --> <div class="post-96609 post type-post status-publish format-standard hentry category-peripherals-hacks tag-cherry tag-g80-3000 tag-keyboard tag-numpad tag-usb"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/23/hacking-the-right-side-of-a-keyboard-completely-off/" title="Hacking the right side of a keyboard completely off" rel="bookmark">Hacking the right side of a keyboard completely off</a></h2> <div class="post-info"><span class="date published time" title="2013-03-23T06:01:04+00:00">March 23, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/mikehackaday/" class="fn n" title="Mike Szczys" rel="author">Mike Szczys</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/23/hacking-the-right-side-of-a-keyboard-completely-off/#comments">12 Comments</a></span> </div> <div class="entry-content"> <p><img class="aligncenter size-large wp-image-96610" alt="hacking-the-right-side-of-your-keyboard" src="http://hackadaycom.files.wordpress.com/2013/03/hacking-the-right-side-of-your-keyboard.jpg?w=580&h=386" width="580" height="386" /></p> <p>The form factor of this keyboard just doesn’t look right. What’s missing? Oh, <a href="http://imgur.com/a/78WwF">the numpad has been completely removed</a>! We use our numpad almost exclusively (especially when coding) so it’s a little hard to figure out why [Ludw] did this. His only mention of motive is that he wanted the mouse closer to the main part of the keyboard and that he didn’t use the numpad. No matter what the reason, we still think he did an amazing job of giving new life to the older keyboard.</p> <p>It started out as a plain old beige Cherry G80-3000 keyboard. After cracking open the case [Ludw] carefully traced out the connections between the key matrix and the PCB which provides the USB connection. This is because the controller is mounted over on the part of the PCB he his about to remove. Before making the cuts he desoldered all seventeen switches (these can be reused to <a href="http://hackaday.com/2011/05/21/bamf2011-keyboards-built-from-scratch/">fabricate a new keyboard</a>, or <a href="http://hackaday.com/2013/01/14/kitchen-scale-key-transplant/">add switches to various projects</a>). He then lopped off the depopulated substrate and used point-to-point soldering to reconnect the controller. A bit of case alteration removed the extra space while also reusing the nicely molded edges. A clean and tidy paint job finishes the hack.</p> <p>[via <a href="http://www.reddit.com/r/DIY/comments/1ar35m/i_modded_my_keyboard_removed_numpad_paintjob/">Reddit</a>]</p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/peripherals-hacks/" title="View all posts in peripherals hacks" rel="category tag">peripherals hacks</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/cherry/" rel="tag">cherry</a>, <a href="http://hackaday.com/tag/g80-3000/" rel="tag">g80-3000</a>, <a href="http://hackaday.com/tag/keyboard/" rel="tag">keyboard</a>, <a href="http://hackaday.com/tag/numpad/" rel="tag">numpad</a>, <a href="http://hackaday.com/tag/usb/" rel="tag">usb</a></span> </div> </div><!-- end .postclass --> <div class="post-96598 post type-post status-publish format-standard hentry category-teardown tag-apple tag-asix tag-ax88772alf tag-bridge tag-ethernet tag-fake tag-knock-off tag-usb"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/22/comparing-usb-to-ethernet-converters-apple-vs-knock-off/" title="Comparing USB to Ethernet converters: Apple vs. Knock-off" rel="bookmark">Comparing USB to Ethernet converters: Apple vs. Knock-off</a></h2> <div class="post-info"><span class="date published time" title="2013-03-22T18:01:53+00:00">March 22, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/mikehackaday/" class="fn n" title="Mike Szczys" rel="author">Mike Szczys</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/22/comparing-usb-to-ethernet-converters-apple-vs-knock-off/#comments">4 Comments</a></span> </div> <div class="entry-content"> <p><img class="aligncenter size-large wp-image-96599" alt="usb-ethernet-comparison" src="http://hackadaycom.files.wordpress.com/2013/03/usb-ethernet-comparison.png?w=580&h=389" width="580" height="389" /></p> <p>[Angus Gratton] recently <a href="http://projectgus.com/2013/03/anatomy-of-a-cheap-usb-ethernet-adapter/">cracked open a pair of USB to Ethernet converters</a> to see what’s inside. One was an Apple branded device, the other a no-name from eBay. The former rings in at $30, with the latter just $4. This type of comparison is one of our favorites. It’s especially interesting with Apple products as they are known for solid hardware choices and <a href="http://hackaday.com/2012/10/10/raspberry-pi-foundation-looks-a-counterfeit-apple-power-supplies/">the knock-offs are equally infamous for shoddy imitations</a>.</p> <p>From the outside both devices look about the same. The internal differences start right away with a whole-board metal shield on the Apple dongle and none on the off-brand. But the hardware inside is actually quite similar. There’s an RJ-45 jack on the left, followed by the Ethernet isolation chip next to it. From there we start to see differences. The off-brand had a blank chip where Apple’s ASIX AX88772ALF USB to Ethernet bridge controller is located. There is also a difference with the clock; Apple is using two crystals with the other using just one.</p> <p>[via <a href="http://www.reddit.com/r/electronics/comments/1an0bj/anatomy_of_a_cheap_usb_to_ethernet_adapter/">Reddit</a>]</p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/teardown/" title="View all posts in teardown" rel="category tag">teardown</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/apple/" rel="tag">apple</a>, <a href="http://hackaday.com/tag/asix/" rel="tag">asix</a>, <a href="http://hackaday.com/tag/ax88772alf/" rel="tag">ax88772alf</a>, <a href="http://hackaday.com/tag/bridge/" rel="tag">bridge</a>, <a href="http://hackaday.com/tag/ethernet/" rel="tag">ethernet</a>, <a href="http://hackaday.com/tag/fake/" rel="tag">fake</a>, <a href="http://hackaday.com/tag/knock-off/" rel="tag">knock-off</a>, <a href="http://hackaday.com/tag/usb/" rel="tag">usb</a></span> </div> </div><!-- end .postclass --> <div align="center"> <script type="text/javascript"><!-- google_ad_client = "ca-pub-1812638130783065"; /* Hackaday, 300x250, created 4/26/08, MedRect main column */ google_ad_slot = "3449215672"; google_ad_width = 300; google_ad_height = 250; //--> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> </div> <div class="post-96593 post type-post status-publish format-standard hentry category-classic-hacks tag-2764 tag-atari tag-atari-800 tag-cartridge tag-eprom"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/22/atari-800-eprom-cartridge-hack/" title="Atari 800 EPROM cartridge hack" rel="bookmark">Atari 800 EPROM cartridge hack</a></h2> <div class="post-info"><span class="date published time" title="2013-03-22T16:01:56+00:00">March 22, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/mikehackaday/" class="fn n" title="Mike Szczys" rel="author">Mike Szczys</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/22/atari-800-eprom-cartridge-hack/#comments">1 Comment</a></span> </div> <div class="entry-content"> <p><img class="aligncenter size-large wp-image-96595" alt="atari-800-eeprom-hack" src="http://hackadaycom.files.wordpress.com/2013/03/atari-800-eeprom-hack.png?w=580&h=355" width="580" height="355" /></p> <p>[Chris Osborn] had an old Atari 800 collecting dust and decided to pull it out and get to work. The problem is that it’s seen some rough storage conditions over the years including what appears to be moisture damage. He’s read about a cartridge called SALT II which can run automatic diagnostics. Getting your hands on that original hardware can be almost impossible, but if he had a flashable cartridge he could just download an image. So <a href="http://www.insentricity.com/a.cl/200/A800-2764">he bought the cheapest cartridge he could find and modified it</a> to use an EPROM.</p> <p>When he cracked open his new purchase he was greeted with the what you see on the left. It’s a PCB with the edge connector and two 24-pin sockets. These are designed to take 4k ROMs. He dropped in an EPROM of the same size but the pin-out doesn’t match what the board layout had in mind. After following the traces he found that it is pretty much an exact match for an Intel 2764 chip. The one problem being that the chip has 28-pins, four too many for the footprint. The interesting thing is that the larger footprint (compared to the 2732) uses all the same pins, simply adding to the top and moving the power pins. A small amount of jumper wire soldering and [Chris] is in business.</p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/classic-hacks/" title="View all posts in classic hacks" rel="category tag">classic hacks</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/2764/" rel="tag">2764</a>, <a href="http://hackaday.com/tag/atari/" rel="tag">atari</a>, <a href="http://hackaday.com/tag/atari-800/" rel="tag">atari 800</a>, <a href="http://hackaday.com/tag/cartridge/" rel="tag">cartridge</a>, <a href="http://hackaday.com/tag/eprom/" rel="tag">eprom</a></span> </div> </div><!-- end .postclass --> <div class="post-96585 post type-post status-publish format-standard hentry category-radio-hacks tag-amateur-radio tag-ham-radio tag-radio tag-uv3r"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/22/writing-new-firmware-for-a-handheld-radio/" title="Writing new firmware for a handheld radio" rel="bookmark">Writing new firmware for a handheld radio</a></h2> <div class="post-info"><span class="date published time" title="2013-03-22T14:00:48+00:00">March 22, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/brianbenchoff/" class="fn n" title="Brian Benchoff" rel="author">Brian Benchoff</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/22/writing-new-firmware-for-a-handheld-radio/#comments">11 Comments</a></span> </div> <div class="entry-content"> <p><img class="aligncenter size-full wp-image-96586" alt="HAM" src="http://hackadaycom.files.wordpress.com/2013/03/ham.jpg?w=580&h=280" width="580" height="280" /></p> <p>When playing around with a cheap, handheld, dual-band radio, [Lior], a.k.a. [KK6BWA], found a schematic for a similar and even cheaper radio. He realized the programming pads were very accessible and the dev tools for the radio’s microcontroller were available from the manufacturer. After these discoveries, there really was only one thing to do: <a href="http://www.liorelazary.com/index.php?option=com_content&view=article&id=51:hacking-the-uv3r&catid=14:baofeng-uv5r&Itemid=17">write new firmware for a $40 radio</a>, and making a great tool for playing around in the 2 meter and 70 cm bands.</p> <p><a href="http://www.liorelazary.com/index.php?option=com_content&view=article&id=51%3Ahacking-the-uv3r&catid=14%3Abaofeng-uv5r&Itemid=17&limitstart=2">The instructions</a> for reflashing the firmware on this radio only require an Arduino and a handful of miscellaneous components. [Lior]‘s <a href="https://github.com/lelazary/UV3RMod">new firmware</a> for the uv3r radio isn’t quite finished yet, but he plans on adding some really impressive features. Things like a better UI for a four-button radio, a mode for tracking satellites, a digital mode, and a computer-controlled mode are all possible and on <a href="https://github.com/lelazary/UV3RMod/blob/master/WISHLIST">[Lior]‘s project wishlist</a>.</p> <p>Getting a $40 radio to do your bidding with an Arduino is cool enough, but [Lior] says this mod for the uv3r can be taken even further: if you’ve got an amateur radio license, it’s possible to use the uv3r to control an Arduino or other microcontroller from miles away. It’s a great hack, right up there with the <a href="http://hackaday.com/2012/03/20/software-defined-radio-from-a-usb-tv-capture-card/">USB TV tuner/software defined radio thing</a> we saw almost exactly one year ago.</p> <p>You can check out a demo of some custom software running on the uv3r after the break. The radio listens for a DTMF tone (supplied by the uv3r’s big brother, the uv5r), and plays back a three-digit DTMF tone. There’s also a more through walk through of what [Lior]‘s new radio can do as well.</p> <p> <a href="http://hackaday.com/2013/03/22/writing-new-firmware-for-a-handheld-radio/#more-96585" class="more-link">[Read more...]</a></p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/radio-hacks/" title="View all posts in radio hacks" rel="category tag">radio hacks</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/amateur-radio/" rel="tag">amateur radio</a>, <a href="http://hackaday.com/tag/ham-radio/" rel="tag">ham radio</a>, <a href="http://hackaday.com/tag/radio/" rel="tag">radio</a>, <a href="http://hackaday.com/tag/uv3r/" rel="tag">uv3r</a></span> </div> </div><!-- end .postclass --> <div class="post-96580 post type-post status-publish format-standard hentry category-3d-printer-hacks category-news tag-3d-printer tag-giveaway tag-lulzbot"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/22/lulzbot-is-giving-away-more-printers/" title="LulzBot is giving away more printers" rel="bookmark">LulzBot is giving away more printers</a></h2> <div class="post-info"><span class="date published time" title="2013-03-22T12:00:10+00:00">March 22, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/brianbenchoff/" class="fn n" title="Brian Benchoff" rel="author">Brian Benchoff</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/22/lulzbot-is-giving-away-more-printers/#comments">1 Comment</a></span> </div> <div class="entry-content"> <p><img class="alignnone aligncenter" alt="" src="http://hackadaycom.files.wordpress.com/2013/02/lulzbot-3d-printer-rt.jpg?w=580&h=379&h=379" width="580" height="379" /></p> <p>LulzBot, the awesomely named 3D printer manufacturer and parts supplier,<a href="https://www.lulzbot.com/?q=news/printer-giveaway"> is giving away eight of their AO-100 printers</a> to eight lucky hackerspaces.</p> <p>It’s not so much a contest, but instead a giveaway aimed at eight community-operated hackerspaces who come up with a great idea on how to use a 3D printer. If you’re part of a well-established hackerspace that doesn’t have a 3D printer yet, this is a great opportunity to get your hands on a very nice printer.</p> <p>A while back, <a href="http://hackaday.com/2013/02/09/adventures-in-3d-printing-our-first-week-with-the-lulzbot-ao-100/">we acquired one of these LulzBot printers</a> to print off some custom gaming controllers for gamers with physical disabilities (and to make some other cool stuff as well). Our boss man [Caleb] says the AO-100 is a great printer, and in my dealings and purchases with LulzBot, they seem like a great company with great support. We’re sure the hackerspaces that win these printers LulzBot is giving away will be able to put them to use quickly by making some really cool stuff.</p> <div id="jp-post-flair" class="sharedaddy sd-like-enabled sd-sharing-enabled"></div> </div><!-- end .entry-content --> <div class="post-meta"><span class="categories">Filed Under: <a href="http://hackaday.com/category/3d-printer-hacks/" title="View all posts in 3d Printer hacks" rel="category tag">3d Printer hacks</a>, <a href="http://hackaday.com/category/news/" title="View all posts in news" rel="category tag">news</a></span> <span class="tags">Tagged With: <a href="http://hackaday.com/tag/3d-printer/" rel="tag">3d printer</a>, <a href="http://hackaday.com/tag/giveaway/" rel="tag">giveaway</a>, <a href="http://hackaday.com/tag/lulzbot/" rel="tag">lulzbot</a></span> </div> </div><!-- end .postclass --> <div class="post-96630 post type-post status-publish format-standard hentry category-news tag-comments tag-dislike-trolls"> <h2 class="entry-title"><a href="http://hackaday.com/2013/03/22/finally-upgrading-our-comment-system/" title="Finally upgrading our comment system." rel="bookmark">Finally upgrading our comment system.</a></h2> <div class="post-info"><span class="date published time" title="2013-03-22T11:38:14+00:00">March 22, 2013</span> By <span class="author vcard"><span class="fn"><a href="http://hackaday.com/author/calebkraft/" class="fn n" title="Caleb Kraft" rel="author">Caleb Kraft</a></span></span> <span class="post-comments"><a href="http://hackaday.com/2013/03/22/finally-upgrading-our-comment-system/#comments">18 Comments</a></span> </div> <div class="entry-content"> <p><a href="http://hackadaycom.files.wordpress.com/2013/03/intense.jpg"><img class="aligncenter size-large wp-image-96631" alt="intense" src="http://hackadaycom.files.wordpress.com/2013/03/intense.jpg?w=580&h=162" width="580" height="162" /></a></p> <p><span style="color:#ff0000;"><strong>UPDATE: I’m working on making the visual style fit better.
