			<content:encoded><![CDATA[<p>Ahh. Summer is here.</p>
<p>Unfortunately for me, I still have a lot of stuff to do. So most of my time is spend in the office.</p>
<ul>
<li>The windows are facing south.</li>
<li>No AC.</li>
<li>A refrigerator creates heat.</li>
<li>So does computers.</li>
</ul>
<p>All in all, the office is hot! Most days between 28-30 degrees Celsius (thats 82-86 for you weird people).</p>
<p>The obvious solution would be to buy a standard electrical fan. Annoyingly, the local supermarket wants 150,- DKK (thats like 25 "bucks").</p>
<p>Instead, I decided to do some procrastination, and try to build my own for about 1/3 of the price.</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0066.jpg"><img title="IMG_0066" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0066-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p><span id="more-45"></span></p>
<p>Turn out the local electronics store had 10 case fans for 60,- DKK (again, more or less equal to $10)!</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0061.jpg"><img class="alignnone size-medium wp-image-39" title="IMG_0061" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0061-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(I got the box for free!)</p>
<p>Time to create a mega-fan!</p>
<h3>Step 1: The tools</h3>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0062.jpg"><img class="alignnone size-medium wp-image-38" title="IMG_0062" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0062-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>Tape, wire, cutting tools, scissor and stuff.</p>
<h3>Step 2: Combine the fans</h3>
<p>I used what I had at hand: wire!</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0063.jpg"><img class="alignnone size-medium wp-image-40" title="IMG_0063" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0063-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(2 by 2)</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0064.jpg"><img class="alignnone size-medium wp-image-41" title="IMG_0064" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0064-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(Then 3 by 3)</p>
<h3>Step 3: Wire up the connectors</h3>
<p>This took some time. Quite a lot of wires!</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0065.jpg"><img class="alignnone size-medium wp-image-42" title="IMG_0065" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0065-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(Two down, 7 to go!)</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0067.jpg"><img class="alignnone size-medium wp-image-44" title="IMG_0067" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0067-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(All wired up, big block of connectors and tape!)</p>
<h3>Step 4: Power it up!</h3>
<p>I have a ATX PSU on my desk just for this kind of projects. These PSUs are magic, 3.3v, 5V, 12V even -12V and lots and lots of Amp!</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0066.jpg"><img class="alignnone size-medium wp-image-43" title="IMG_0066" src="http://blog.ptx.dk/wp-content/uploads/2010/07/IMG_0066-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(It's spinning!)</p>
<p>All the fans worked on the first try! (Well almost, one soldering fell of after couple of minutes, but that was an easy fix!)</p>
<h3>Step 5: Conclusion</h3>
<p>Worst idea EVER!</p>
<p>Computer case fans are created for cooling... computers. NOT humans.</p>
<p>The monster fan is silent, but creates practically no airflow.</p>
<p>Back to the drawing board!</p>

<p>Logic be dammed! We put them on the bottom!</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00060.jpg"><img class="alignnone size-medium wp-image-67" title="DSC00060" src="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00060-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(Pure magic)</p>
<p><span id="more-66"></span></p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00061.jpg"><img class="alignnone size-medium wp-image-68" title="DSC00061" src="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00061-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(Thats standard danish beer hanging from the shelf)</p>
<p><a href="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00062.jpg"><img class="alignnone size-medium wp-image-69" title="DSC00062" src="http://blog.ptx.dk/wp-content/uploads/2010/07/DSC00062-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>(Look! magnets!)</p>
<p>These magnets are called neodymium magnets and are incredible powerful!</p>
<p>The easiest place to find some are inside old hard drives. Or buy them <a href="http://www.supermagnete.de/eng/">online</a> like we did!</p>
