      <title>When Oakley Meets Camera</title>
      <link>http://gadgetopia.com/post/5849</link>
      <description><![CDATA[<p>When the Oakley CEO starts a camera company, <a href="http://red.com/cameras.htm">here is what it looks like</a>.</p>

<blockquote>
  <p>Typical high-end HD camcorders have 2.1M pixel sensors and record with 3:1:1 color subsampled video at up to 30fps. We deliver 12M pixels at up to 60fps and record RAW, or 2x over-sampled HD in 4:4:4 or 4:2:2 -- your choice. That's more than 5 times the amount of information available every second and a vastly superior recording quality.</p>
  
  <p>Don't need all that data for your workflow? Dial it back, and keep all the other advantages of the Mysterium Super 35mm cine sized (24.4 x 13.7mm) sensor. You get the same breathtaking Depth of Field and selective focus as found in film cameras. Mysterium boasts a greater than 66db Signal to Noise Ratio thanks to its large 29 sq. micron pixels. And 12,065,000 pixels deliver resolution that can only be called Ultra High Definition.</p>
</blockquote>

<p>Only $17,500.</p>

<p>Also, I wonder how much <a href="http://red.com">red.com</a> cost him?</p>

      <title>TechTool Protege</title>
      <link>http://gadgetopia.com/post/5329</link>
      <description><![CDATA[<p>In the days before OS X, if you had trouble with a hard drive, you could simply stick a utility disk in the CD drive &amp; boot into a working Finder, fix the problem, plus a whole lot more, just booted from the CD. With OS X, you can still boot from an optical disk, but only into the environment that the disk allows &mdash; not into the Finder, which severely limits what you can do with the machine and the files on the hard drive. That's been a primary and legitimate gripe many of us have had with OS X since it was first introduced.</p>

<p>To get around those limitations, Micromat has started packaging <a href="http://micromat.com/index.php?option=com_content&amp;task=view&amp;id=31&amp;Itemid=83">TechTool Pro</a> with a 1GB Firewire flash drive &mdash; the <a href="http://micromat.com/index.php?option=content&amp;task=view&amp;id=34">TechTool Protege</a>. Pure genius. With TechTool Protege you can boot into a workable operating system to run TechTool Pro (or any other utility you can fit into the drive), back up files over the network, or whatever.</p>

<p>Lots of people who support Macs have been doing something like this since... forever. When I started working with Macs in 1995, I kept a floppy disk with a system folder &amp; a few tools on it that could boot and fix anything from an <a href="http://lowendmac.com/compact/se.shtml">SE</a> to the mighty <a href="http://lowendmac.com/quadra/q950.shtml">Quadra 950</a>. That eventually morphed into a spare SCSI drive in an external case, then various CD's with the current version of Dave's Essentials Toolkit. These days I keep a Firewire case with a spare 20GB laptop drive loaded with a current OS install and a bevy of diagnostic &amp; repair tools. It has enough space to back up most user's files in case a wipe &amp; reinstall is needed (can't say I've ever had to resort to that.) </p>

<p>While Micromat's idea is neither cheap ($229) nor unique in the Macintosh world, it is unique in the market; all the other Mac disk utilities that I know of use a bootable CD. Hats off to them for listening to their users &amp; making a truly useful tool.</p>

      <title>Pirates Fought Off With Hi-Tech Weaponry</title>
      <link>http://gadgetopia.com/post/4593</link>
      <description><![CDATA[<p><a title="CNN.com - Cruise ship 'used sonic weapon' - Nov 8, 2005" href="http://www.cnn.com/2005/WORLD/africa/11/07/somalia.pirates.sonic.ap/index.html">Cruise ship 'used sonic weapon'</a>: Interesting details are emerging about the pirate attack Dave <a href="http://www.gadgetopia.com/post/4585">posted</a> the other day.  Apparently the cruise ship was somewhat geeked out.</p>

<blockquote>
  <p>The crew of a cruise ship attacked by pirates off the coast of Somalia used a sonic weapon to help ward off the attackers [...]</p>
  
  <p>The device blasts earsplitting noise in a directed beam.</p>
  
  <p>The sonic device, known as a Long Range Acoustic Device, or LRAD, is a so-called "non-lethal weapon" developed for the military after the 2000 attack on the USS Cole in Yemen as a way to keep operators of small boats from approaching U.S. warships.</p>
</blockquote>

<p>That article has a picture of the pirates shot by a passenger.  I guess "pirate" is code for "idiot in a shrimp boat with a crappy gun."</p>

      <title>iPod Nano Upgrade</title>
      <link>http://gadgetopia.com/post/4429</link>
      <description><![CDATA[<p>Of all the silly... </p>

<p><a href="http://uncyclopedia.org/wiki/Ipod_Nano_200gb_Instructions/Page_1">Some guy</a> tore apart a perfectly good <a href="http://www.apple.com/ipodnano/">iPod Nano</a> and connected a 200GB Maxtor hard drive to it. Amazingly, it worked. The capacity increased by 50x, but battery life dropped to about 6 minutes. </p>

<p>Somehow that doesn't seem like a good tradeoff for a portable.</p>

<p>On the other hand, if you were to do this hack &amp; hook the Nano up to a set of <a href="http://www.gadgetopia.com/post/4400">Logitech X-230's</a>, or maybe one of those spiffy $30 <a href="http://www.amazon.com/exec/obidos/tg/detail/-/B00009W44B/qid=1128394136/sr=8-1/ref=pd_bbs_1/102-0202618-3044957?v=glance&amp;s=electronics&amp;n=507846">Sonic Impact T-Amps</a> and a good set of Bose speakers...

<p>The $29.99 pocket-sized digital video cameras are able to capture up to 20 minutes of video and sound.</p>

<p>CVS Corp. stores, which has exclusive rights to sell them, will process the camera for $12.99 and return a DVD; users also can e-mail video and video greeting cards.</p>

      <title>No More Shut-eye In Digital Pics</title>
      <link>http://gadgetopia.com/post/3917</link>
      <description><![CDATA[<p>Rob should appreciate this one:</p>

<blockquote>

<p>Digital images featuring someone in mid-blink could be banished forever using an image-analysis system for cameras developed in Japan.</p>

<p>The system developed by Kaneko's team gets around the problem by snapping 15 frames in 0.5 seconds after the shutter button is clicked. A computer then rapidly analyses these image, discarding those in which the subject is blinking, leaving photographer with a better final snap.</p>

      <title>PQI Intelligent Stick</title>
      <link>http://gadgetopia.com/post/3514</link>
      <description><![CDATA[<p>I had to buy some USB keys recently to store login credentials. Without the files on the key, you wouldn't be able to log in to the system, period. I dreaded the issues that were sure to arise when people left their USB keys at home, in their car, etc. </p>

<p>Then I found <a href="http://www.pqi1st.com/products/istick.asp">PQI's Intelligent Stick</a> online. They're what might happen if a secure digital card and a USB stick had a baby. </p>

<p>The thing is only about the thickness of one penny and the length of two pennies side-by-side. There's no metal shield around the USB contacts on the business end, further reducing the size. You just wedge it into a USB slot. </p>

<p>It comes with a holder that fits in your wallet, and it's no thicker than three or four credit cards. No forgotten USB sticks. </p>

<p>It looks like PQI is trying to market these as an alternative to the current flash memory formats used by cameras and MP3 players. So I can just pull the memory out of the camera, jam the business end into the USB port on my computer, and off I go? Sounds like a great idea to me. </p>

<p>The only downside I've found is that they appear to be pretty power-hungry (which may kill the whole camera/MP3 player idea). If I put it in the unpowered USB hub built into my keyboard (as I've always done without issue using my Kingston stick), Windows complains and it's a no-go. Works fine in the port on the PC, though, and I'm sure it would be OK with a powered hub.</p>

      <description><![CDATA[<p>...or in your PDA, or in your laptop, or in your kids' toys... </p>

<p>According to an <a href="http://www.technologyreview.com/articles/04/11/freedman1104.asp">article</a> in Technology Review, the uber-geeks at MIT are working on turbines the size of a dime, spin at over a million RPM's, and may one day provide power for the gadgets you use. </p>

<blockquote>

<p>A micro gas turbine engine... could run for ten or more hours on a container of diesel fuel slightly larger than a D battery; when the fuel cartridge ran out, a new one could be easily swapped in. Each disposable cartridge would pack as much energy as a few heavy handfuls of lithium-ion batteries. As a result, a small pack of the cheap and light cartridges could power a PDA or cell phone through several days of heavy usage, no wall-outlet recharging required &mdash; a highly attractive feature for soldiers in remote locations or travelers. What's more, the miniature turbine takes up about a quarter of the volume of a typical cell-phone battery.</p>

</blockquote>

<p>I would think that these mini jet engines could use just about anything for fuel; JP-4, diesel, kerosene, biodiesel, alcohol, etc... One of the big hurdles to overcome &mdash; aside from just getting parts that small to spin that fast without self-destructing &mdash; is going to be waste heat. Imagine carrying a tiny little furnace around in your pocket... Maybe a teeny tiny air conditioner?</p>
