			<content:encoded><![CDATA[<p><img width="425" vspace="4" hspace="4" height="318" border="0" src="http://hackadaycom.files.wordpress.com/2007/10/scaled.hoopty1.jpg?w=425&#038;h=318" alt="" /><br />We didn&#8217;t even pause for a second when offered a chance to tour Mr. Jalopy&#8217;s studio. Even if it meant a 600 mile roundtrip, we&#8217;d be there. You&#8217;ll probably recognize Mr. Jalopy as the author of <a href="http://hooptyrides.blogspot.com/">Hoopty Rides</a> and as a frequent <a href="http://www.makezine.com/">Make Magazine</a> contributor know for his <a href="http://hooptyrides.blogspot.com/2005/08/megagiant-wood-ipod-eliminates-mugging.html">giant iPod</a> and <a href="http://hooptyrides.blogspot.com/2007/05/mister-jalopys-urban-guerrilla-movie.html">guerilla projector</a>. <a href="http://www.dorkbot.org/dorkbotsocal/">Dorkbot SoCal</a> organized a studio tour so that fellow hackers could pick up some of the Hoopty Rides secret sauce.</p>
<p><span id="more-1493"></span></p>
<p><img width="425" vspace="4" hspace="4" height="318" border="0" src="http://hackadaycom.files.wordpress.com/2007/10/scaled.hoopty2.jpg?w=425&#038;h=318" alt="" /><br />Mr. Jalopy spent a long time searching for his shop. He wanted a site that he could work in, but was self-sufficient. The location is paid for by a small retail shop upstairs plus a freeway visible billboard. It&#8217;s and old car repair shop with two bays and some interesting quirks like 400hp water break dynamometer (gauges at top) and an <a href="http://www.flickr.com/photos/hackaday/1567482208/in/set-72157602410791592/">old hydraulic lift</a> designed just for cars with solid rear axles. He got a unused second Clayton 200hp dynamometer (above) for cheap and plans on combining the two to hopefully get a nice functional unit.</p>
<p><img width="425" vspace="4" hspace="4" height="318" border="0" src="http://hackadaycom.files.wordpress.com/2007/10/scaled.hoopty3.jpg?w=425&#038;h=318" alt="" /><br />He pointed out the boombox TV he had built stating that it was the subject of an upcoming article. It won&#8217;t be about the construction of the boombox though; the article is about Boombox: The Platform. He&#8217;s quite fond of picking up boomboxes at garage sales because of what you get: an AC/DC converter, a battery holder, amplifier, speakers, lots of switches, buttons, and knobs, all for $1 and a nice box to boot. The monitor for this one was the cheap PSOne flip up screens we&#8217;ve mentioned before. The tuner is a fairly versatile and is designed for car use.</p>
<p><img width="425" vspace="4" hspace="4" height="318" border="0" src="http://hackadaycom.files.wordpress.com/2007/10/scaled.hoopty4.jpg?w=425&#038;h=318" alt="" /><br />A common theme was was that Mr. Jalopy doesn&#8217;t feel he knows how to do a lot of stuff, but that doesn&#8217;t matter because he can manage by doing things he does know. Take the giant iPod for example. The big attraction is that the old console radio&#8217;s buttons actually control the iPod. He didn&#8217;t get hung up wondering how he was going to send the iPod commands over the serial interface; he just bought an <a href="http://www.griffintechnology.com/products/airclick/">AirClick</a> and soldered wires directly to the board. Other good advice: Don&#8217;t half-ass, build it so it lasts. Also, build in adjustment since you won&#8217;t get it perfect the first time.</p>
<p><img width="425" vspace="4" hspace="4" height="318" border="0" src="http://hackadaycom.files.wordpress.com/2007/10/scaled.hoopty5.jpg?w=425&#038;h=318" dragover="true" alt="" /><br />A minor attraction that I found very interesting was his <a href="http://en.wikipedia.org/wiki/Curta">Curta calculator</a>. The Curta was invented by Curt Herzstark during WWII while he was a prisoner in a concentration camp and was popular up to the 70s. The side has 11 single digit sliders on screw shafts. Turning the crank on the top a full rotation adds the side number to the top result display. It also subtracts and does many more complex operations. Here&#8217;s a <a href="http://www.vcalc.net/curta_simulator_en.htm">flash demo</a> of the device.</p>
<p>I&#8217;ll add photo links as the come in, but for now you can view <a href="http://www.flickr.com/photos/youraccount/sets/72157602409017186/">Garnet Hertz&#8217;s</a>, <a href="http://www.flickr.com/photos/coop666/sets/72157602410301380/">COOP&#8217;s</a>, and <a href="http://www.flickr.com/photos/hackaday/sets/72157602410791592/">mine</a>. Also, look for the tour on a future episode of <a href="http://tv.boingboing.net/">BoingBoingTV</a> (not <a href="http://www.flickr.com/photos/hackaday/1566572155/in/set-72157602410791592/">Make:TV</a>, I don&#8217;t think that&#8217;s been announced yet ;-)</p>
<p>We&#8217;d like to thank Dorkbot SoCal, Mr. Jalopy, and all the people we met for the wonderful experience.</p>
