<p>We spent yesterday evening out around town with our projector and new power inverter, testing sight-lines and potential backup locations for the <a href="http://www.brokencitylab.org/cross-border-communication/" target="_blank">Cross-Border Communication</a> project.</p>
<p>We&#8217;re getting close to knowing exactly how and when we&#8217;ll get to do this project, and you can see our research and field tests after the jump.</p>

<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3953.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3953.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>We&#8217;ve been anxious to pick up this piece of equipment and everything finally came through yesterday to allow us to do just that.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3955.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3955.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Thanks to the generosity of the University of Windsor&#8217;s Faculty of Arts and Social Sciences Research Leadership Chair, we were able to get an <a href="http://www.canadiantire.ca/browse/product_detail.jsp?FOLDER%3C%3Efolder_id=2534374303523074&amp;bmUID=1238525861757&amp;PRODUCT%3C%3Eprd_id=845524443291417&amp;assortment=primary&amp;fromSearch=true" target="_blank">1800W inverter</a> to power our projector and laptop without being tethered to an outlet.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3956.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3956.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Taking the inverter out of the box and pressing the ON button.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3960.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3960.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>We have lights and a good charge right out of the box.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3964.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3964.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The moment of truth, plugging in the projector.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3966.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3966.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>We have power!!!</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3968.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3968.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The system works exactly as we had hoped.</p>
<p><img class="alignnone size-full wp-image-5826" title="Broken City Lab first test" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/40401844.jpg" alt="Broken City Lab first test" width="480" height="640" /></p>
<p>And the first test at BCL HQ. We were also meeting with Lee Rodney to talk about an upcoming collaboration with her <a href="http://www.borderbookmobile.net/" target="_blank">Border Bookmobile</a> project. So Lee came out with us on our outdoor projection + battery test adventures.</p>
<p><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3975.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></p>
<p>We wanted to check the visibility at a distance, a further distance than we&#8217;ve tested in the past, so we headed to the University of Windsor campus.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3972.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3972.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>From the parking lot across from the new medical building, we set up our projector, laptop and new power inverter. Michelle and Josh set up, Rosina holding the projector.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3977.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3977.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Cristina sets up to take some photos with Lee before heading north on Sunset to check the visibility of the projection from a distance. We were trying to project onto the side of Lambton Tower, but so much light was passing through the windows, it wasn&#8217;t working very well. Unfortunately ,this is likely indicative of what will happen on the side of the CIBC building.</p>
<p><img class="alignnone size-full wp-image-5775" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3692.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></p>
<p>The projection was a bit weak given the distance we were from the building. The edge of the parking lot has to be around 150&#8242; from the building we were projecting onto and that distance along with the height of the building and overall brightness of the night with the full moon didn&#8217;t provide ideal conditions for projecting.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3690.jpg"><img class="alignnone size-full wp-image-5774" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3690.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The view from a little further down on Sunset Ave. We also had the help of <a href="http://web4.uwindsor.ca/president" target="_blank">University of Windsor&#8217;s president</a>, Dr. Alan Wildeman, who offered to drive down to Riverside Drive and back to tell us where the projection was most visible. He reported that there wasn&#8217;t a very ideal sight-line given the number of trees on Sunset, but as you can see the projection itself just wasn&#8217;t bright enough.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3978.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3978.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Projecting onto a much closer building worked a lot better.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3699.jpg"><img class="alignnone size-full wp-image-5776" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3699.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>This is the new medical building, for those of you who have seen the Lebel building, you can understand our envy.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3708.jpg"><img class="alignnone size-full wp-image-5777" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3708.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>After testing on campus, we decided to go downtown. We wanted to find some other potential surfaces, given our conclusions about the difficulties of projecting onto windows.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3716.jpg"><img class="alignnone size-full wp-image-5778" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3716.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The side of the Art Gallery of Windsor provides a good, bright surface.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3718.jpg"><img class="alignnone size-full wp-image-5780" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3718.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>This is the view from the riverfront.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3719.jpg"><img class="alignnone size-full wp-image-5781" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3719.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>And another view with a longer exposure.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3726.jpg"><img class="alignnone size-full wp-image-5782" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3726.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>This view is a bit misleading for the visibility of the projection, as the riverfront park is at a lower grade than the view from Detroit would present.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3732-1.jpg"><img class="alignnone size-full wp-image-5783" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3732-1.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="346" /></a></p>
<p>After testing on the AGW, we moved further east.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3738_2.jpg"><img class="alignnone size-full wp-image-5786" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3738_2.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="346" /></a></p>
<p>We thought that all of the closed curtains on the Hilton would provide a brighter surface, and it might, but our projector just isn&#8217;t powerful enough.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3740.jpg"><img class="alignnone size-full wp-image-5787" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3740.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="346" /></a></p>
<p>The Broken City Lab crew.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3744_2.jpg"><img class="alignnone size-full wp-image-5788" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3744_2.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="346" /></a></p>
<p>While we were there, we also tested on the Radisson, which would probably be another good potential surface with a more powerful projector.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3759.jpg"><img class="alignnone size-full wp-image-5789" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3759.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Next we headed to the riverfront to try a quick test on the river itself, something we&#8217;ve been meaning to do.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3761.jpg"><img class="alignnone size-full wp-image-5790" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3761.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Then we went down to the Daimler Chrysler building for the final tests of the night.</p>
<p><img class="alignnone size-full wp-image-5793" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3768.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></p>
<p>This is another really good surface, but the height makes us unsure of how well you could see it from Detroit.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3768.jpg"></a><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3987.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3987.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Rosina being a trooper and holding the projector again.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3989.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3989.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Josh, Lee, and Michelle check out the projection.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3991.jpg"><img title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3991.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The view from just east of where we were projecting from.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3775.jpg"><img class="alignnone size-full wp-image-5794" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3775.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The view at the foot of Ouellette and the Detroit River.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3779.jpg"><img class="alignnone size-full wp-image-5795" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3779.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The size of the test of close to what we need. But again, the height makes us unsure.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3789.jpg"><img class="alignnone size-full wp-image-5797" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3789.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Some more views.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3792.jpg"><img class="alignnone size-full wp-image-5799" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3792.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>Here you can see the projection next to the CIBC building that we had originally planned to project onto. You can see there might be a number of issues with the building, which we had considered before, but are more fully realizing after our tests tonight. The windows probably wouldn&#8217;t reflect enough light, letting too much of it into the office space.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3795.jpg"><img class="alignnone size-full wp-image-5800" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3795.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>From the edge of the cul-de-sac at the edge of  the river.</p>
<p><img class="alignnone size-full wp-image-5827" title="IMG_3217" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3217.jpg" alt="IMG_3217" width="520" height="390" /></p>
<p>This is from a photo taken earlier this year, this is the size and view of the building we were projecting onto.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3803-1.jpg"><img class="alignnone size-full wp-image-5803" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3803-1.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="346" /></a></p>
<p>So, this size of projection is potentially workable, though in some ways, having two projectors would be great and give us a lot more length. For now, it was a successful test, and we&#8217;re becoming more familiar with the limitations of our 2800 lumens projector.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3805.jpg"><img class="alignnone size-full wp-image-5806" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3805.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>The view from the parking lot.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3811.jpg"><img class="alignnone size-full wp-image-5807" title="November 3, 2009 Projection + Battery tests by Broken City Lab" src="http://www.brokencitylab.org/wp-content/uploads/2009/11/IMG_3811.jpg" alt="November 3, 2009 Projection + Battery tests by Broken City Lab" width="520" height="347" /></a></p>
<p>We miss you!!!</p>
<p>We&#8217;ll have to connect with some folks we know in Detroit to test the visibility from one of these alternate downtown locations. In the meantime, we&#8217;re still hoping to get our hands our a higher-powered projector, because no matter what we project onto, having more light can only help.</p>

<p>I got the needed resistors right before Christmas, though hadn&#8217;t had a chance to post this yet. As you can see, there&#8217;s a 270Ω resistor, a 9V battery, and a 10mm LED working&#8230; along with the resistors, I got a 9V power supply, so we can make signs and run them off the wall, rather than relying on a ton of batteries. As I&#8217;m unsure about just how long a whole bunch of LEDs could run on battery, I suppose depending on the size of the batteries this could vary&#8230; connecting a bunch of D batteries to add up to 9V will certainly last longer than one of these alone.</p>
<p>We&#8217;ll get started on this soon.</p>

<p>The 10mm LEDs I ordered from <a href="http://evilmadscience.com/partsmenu">Evil Mad Science</a> came in and I went out today to get a CR2032 3V battery to start testing. </p>
<p><span id="more-414"></span><a href="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1007.jpg"><img class="alignnone size-full wp-image-416" src="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1007.jpg" alt="the bag of 100 LEDs" width="520" height="390" /></a></p>
<p>I got 100 super white and 100 blue LEDs.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1010.jpg"><img class="alignnone size-full wp-image-417" src="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1010.jpg" alt="CR2032 3volt battery" width="520" height="390" /></a></p>
<p>This is the CR2032 battery, I got 6 of them for $2 from the Dollar Store. It would be interesting to get a really small solar cell to keep a battery like this continuously charged.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_0999.jpg"><img class="alignnone size-full wp-image-418" src="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_0999.jpg" alt="5 LEDs powered from 1 CR2032 battery" width="520" height="390" /></a></p>
<p>You can power more LEDs off of one battery, but I think the battery would just drain faster.</p>
<p><a href="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1001.jpg"><img class="alignnone size-full wp-image-419" src="http://www.brokencitylab.org/wp-content/uploads/2008/12/img_1001.jpg" alt="5 LEDs glowing, powered from 1 CR2032 battery" width="520" height="390" /></a></p>
<p>These are the blue LEDs, the whites are a bit brighter, but still have the frosted lens. So, let&#8217;s start thinking about what we can do&#8230; I want to make some signs, use these to light up that fence entrance for Lebel and the wall where there is no light.</p>
