<p><a href="http://www.headfullofair.com/wp-content/uploads/2009/12/P1010389_crop.jpg"><img class="alignnone size-medium wp-image-227" title="I signed it in stamped aluminum" src="http://www.headfullofair.com/wp-content/uploads/2009/12/P1010389_crop-300x70.jpg" alt="I signed it in stamped aluminum" width="300" height="70" /></a></p>
<p>There are many reasons to love <strong><a href="http://www.headfullofair.com/2009/05/17/what-the-butler-saw/">mutoscopes</a></strong>, from nostalgia to mechanical beauty, but any expensive niche medium competing with less expensive and widely available systems must have a design rationale and purpose in it&#8217;s own right beyond the purely aesthetic.  Within the context of the art world mutoscopes have a place as more than a curiosity- they are a solution to a real problem facing animators like Fernando.</p>
<p>Fernando Renes is an animator but his drawings don&#8217;t move.  All of his animations are digital movies of static drawings one degree removed from his works on paper.  If you want to see his work, you&#8217;ll have to go to a gallery or museum showing them, because Fernando&#8217;s income is dependent on the sales of limited editions his animations.  He can&#8217;t just post a video to YouTube, it would devalue the work of his collectors.  Online and in print there are plenty of stills from his work, but you can&#8217;t see any reproduction of his finished pieces anywhere outside of a gallery.</p>
<p>This is problematic for Fernando and other animators in the fine art world, as well as for the art world in general.   Painters can be known by their prints- I don&#8217;t have to fly to Paris to have seen the Mona Lisa- because prints don&#8217;t devalue the originals.   But animators&#8217; drawings don&#8217;t move, only the movies of their drawings do (Harry Smith, Stan Brackage, and other film scratchers excepted).  The &#8220;original&#8221; is always a print, and the number of prints must be severely limited to control their value so the artist can make a living.</p>
<p>Animators are therefore marginalized within the fine art world.  Their work is the hardest to see, so fewer people know of them than artists in other media.  Critics, students, and art lovers can&#8217;t sit with the work and come to know it they way they can when good prints exist.  As a result, the entire field lacks a sense of history and development.</p>
<p>Large-scale mutoscopes can address this problem for Fernando and other animators that draw animations frame by frame.  A mutoscope is a circular flip book with it&#8217;s pages radiating out from a central binding, played in a mechanical player.  Traditionally they were used for photo reproduction of short peep show movies.  The Mutoscope for Fernando is for original drawings, and so must be  substantially larger (4&#8243; x  3&#8243; drawing area) than a traditional mutoscope<a href="http://en.wikipedia.org/wiki/Mutoscope"> (1 7/8&#8243; square)</a>.   The Mutoscope for Fernando can accept reels of original drawings from 500 to 2500 frames in length, or 30 seconds to 3 minutes, playing back at 8-16 frames per second.</p>
<p>By drawing directly into mutoscope reels, Fernando can make his original drawings move, creating an original object bearing his mark as an artist that is also an animation.  Since it is an original,  &#8220;prints&#8221; may be made from it- movies of the machine in action- that have the same relationship that paintings bear to prints.  My hope is that mutoscopes can bring the same level of study and distribution to Fernando&#8217;s animation that paintings currently enjoy, strengthening the art world and widening his audience.</p>

<p>Between coats of paint and sealer, waiting for the last epoxy bonds to take hold, and tweaking the Mutoscope&#8217;s tripod I&#8217;ve played around with small mutoscope reels.  Last year I tried making one out of paper with a craft knife, but the accuracy of a knife and flimsiness of paper got the better of me.</p>
<p><a href="http://www.headfullofair.com/wp-content/uploads/2009/11/P1000477_sm.jpg"><img class="alignnone size-medium wp-image-204" title="Failed paper mutoscope, May 2008" src="http://www.headfullofair.com/wp-content/uploads/2009/11/P1000477_sm-300x169.jpg" alt="Failed paper mutoscope, May 2008" width="300" height="169" /></a></p>
<p>Now, with the help of Matt, and Raphael, and especially Kelly at <strong><a href="http://www.nycresistor.com/">NYC Resistor</a></strong>&#8216;s craft night I cut a 500-card capacity hub based on the original dimensions of the <strong><a href="http://www.headfullofair.com/2009/05/17/what-the-butler-saw/">Kinora.</a></strong> Wonderfully meta: the Kinora hub is laser cut out of spare Mutoscope cards.  A miniature mutoscope manufactured from a super-sized one.  If I can dig up the material and machine time I&#8217;ll cut enough cards to fill it.  <strong> <a href="http://www.headfullofair.com/wp-content/uploads/2009/11/2_3-8_kinora_2.ai_.zip">Or you could make your own (here&#8217;s the .ai file).</a></strong></p>

			<content:encoded><![CDATA[<p>Kris de Decker produces some of the<strong> </strong><a href="http://www.lowtechmagazine.com/2008/10/led-light-cfl-b.html"><strong>most insightful</strong> </a>and <strong><a href="http://www.lowtechmagazine.com/2008/11/tiles-vaults.html">well-researched articles</a></strong> on technology anywhere on the internet.  He has a simple premise- novel &#8220;high-tech&#8221; solutions aren&#8217;t always that great.  Don&#8217;t give up on established, simple, and efficient solutions to human problems.  He just <strong><a href="http://www.notechmagazine.com/2009/11/kinematic-models.html">linked back to me</a> </strong>when I pointed him to KMODDL, and I wanted to share some stuff he&#8217;s posted, since it&#8217;s been sitting in my &#8220;to post&#8221; folder since August:</p>
<p>Kris often finds works from another age whose techno boosterism is familiar, but whose object is odd to a contemporary reader. From the height of airship mania ( Zeppelin&#8217;s commercial air transport service was established a year later) and before airplanes proved themselves in the skies, <strong><a href="http://www.notechmagazine.com/2009/06/airships-past-and-present-by-ahildebrandt-1908.html">Airships Past and Present (1908)</a></strong> is a fantastic snapshot of globalized tinkering and ingenious innovations:</p>
<p>In 1792, Uyton de Morveau recieved official instructions from Napoleon to develop military balloons.  Morveau developed a team with chemist Lovoisier and physicist Coutelle,  and together they developed a novel hydrogen generator that used a hot iron with steam passing over it, and a novel means of sealing silk balloons with 5 layers of linseed oil based varnish.  The varnish was particularly effective, holding hydrogen in the balloon for upwards of 2 months, but the recipe is lost to history.  The envelope of a hydrogen balloon capable of carrying 2 passengers to 1600ft  would weigh only 180-200lbs, in line with early 20th century numbers (134).</p>
<p>OR:</p>
<p>My favorite balloon of the period, the Parseval-Sigfeld, featured with hard numbers on wind speed (66ft per second).  Parseval invented the &#8220;sausage&#8221; balloon design that once refined was deployed by Germany, France, and to great effect Belgium in WWI.  But this text is of course from before the war (209, 211, 274).</p>

			<content:encoded><![CDATA[<p>Two other people making mutoscopes:</p>
<p><strong><a href="http://www.youtube.com/watch?v=HCJeOca-GQU&amp;feature=player_embedded">The Process Enacted Mutoscope</a></strong> uses over 900 Polaroids, and is <strong><a href="http://www.thechasefactory.com/mutoscope.html">finished elegantly</a></strong>, but runs in spits.  One immediate refinement I&#8217;d suggest is to change the gearing.  It looks like it&#8217;s geared 1:1 or 2:1. I bet if they geared down the crank 20:1 or more the flipping of the cards would be much smoother. A worm drive is nearly ubiquitous amongst <strong><a href="http://www.headfullofair.com/2009/05/17/what-the-butler-saw/">classic mutoscopes</a></strong>.<br />
<strong><a href="http://cortese.publishpath.com/">Sergey Gavrilenko</a></strong>, Director of the <strong><a href="http://www.youtube.com/watch?v=GAfAVZ4hHMQ">Museum of the History of the Development of the World Cinemagraphic Technology</a></strong> in Kiev, Ukraine, contacted me about his <strong><a href="http://cortese.publishpath.com/gallery">superb mutoscope</a></strong>, a historical reproduction similar to this one in the <strong><a href="http://www.geh.org/fm/precin/htmlsrc/mA512600001_ful.html">Eastman Collection</a></strong>.  More impressive than his mutoscope are his<strong> <a href="http://cortese.publishpath.com/gallery">functioning miniature film projectors</a></strong>.   I wish there was a video of them running.  Movies on microfilm are another Atomic Age sci-fi dream dashed by magnetic storage.</p>
<p>Look for miniature projectors starting at 1:57 in this video</p>

			<content:encoded><![CDATA[<p>Fernando Renes&#8217; animation finally came back from the printer&#8217;s last weekend, and Molly helped me bind it into a mutoscope reel.  since my last post everything has been re-built except the projector (I&#8217;m re-building the projector today to cut down on light leaks and get better contrast).  The machine is not quite done, but I felt a wave of success on Thursday night, showing it to Fernando, and then Josiah and Taiwon.

			<content:encoded><![CDATA[<p>A good chunk of <span><span>Toorcamp</span></span> <span>occurred</span> in a Titan 1 missile silo amongst a complex of hemispherical blast domes.  The power dome is the largest and least obstructed of these, and the open space obliterated sound into crackling and unfocused echos. <a href="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040957.jpg"><img class="alignnone size-medium wp-image-69" title="Titan 1 Blast Dome, Toorcamp 2009" src="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040957-300x168.jpg" alt="p1040957" width="300" height="168" /></a><br />
Standing in the dome I drifted back to my obsession of the last two months- the R &amp; D of an updated <strong><a href="http://www.headfullofair.com/2009/05/17/what-the-butler-saw/"><span><span>mutoscope</span></span></a></strong> standard.  I&#8217;m using hemispherical reflectors in <span><span>mutoscope&#8217;s</span></span> opaque projector, and although my intuition lead me toward this shape, I didn&#8217;t really understand how it worked until standing in the blast dome, trying to make out a human voice.<br />
Classically,<a href="http://www.headfullofair.com/2009/05/17/what-the-butler-saw/"> <strong><span><span>mutoscopes</span></span> use peep viewers</strong></a>, but I thought that a thoroughly modern <span><span>mutoscope</span></span> would project either internally or externally to an appropriate home viewing size of about 20&#8243; diagonal.   But <strong><a href="http://www.luikerwaal.com/newframe_uk.htm?/epidia_uk.htm">opaque projectors</a></strong> are extremely inefficient.  I can only assume that inefficiency, heat stress, and poor image quality doomed <strong><a href="http://www.time.com/time/magazine/article/0,9171,711649-1,00.html">William <span><span>Rabkin&#8217;s</span></span></a></strong> patented 1933 (#2,070,840) <span><span>mutoscope</span></span>.</p>
<p><a href="http://www.headfullofair.com/wp-content/uploads/2009/07/01_02070840_exp.png"><img class="alignnone size-medium wp-image-70" title="Side view of Rabkin's projection Mutoscope, patent #02070840, 1933" src="http://www.headfullofair.com/wp-content/uploads/2009/07/01_02070840_exp-300x230.png" alt="Side view of Rabkin's projection Mutoscope, patent #02070840, 1933" width="300" height="230" /></a></p>
<p>Most commercial designs consist of a single <span>light bulb</span> in a reflective box.  The projected image is riven with glare in cheap models and <span>vignetting</span> in even the best projectors.   I figured I could do better.<br />
In an attempt to out-do existing projectors, I decided to directly illuminate the projected page with spot lights.  But no matter what the configuration of the lights I couldn&#8217;t throw an even light across the projected image, and I got even more nasty hot spots and glare than commercial projectors.</p>
<p><a href="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040354c.jpg"><img class="alignnone size-medium wp-image-71" title="My original idea, it didn't work out" src="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040354c-300x269.jpg" alt="My original idea, it didn't work out" width="300" height="269" /></a><br />
But walking down Union st in Brooklyn one Sunday, I noticed a standard clamp light with a diffusion powder coat on the inside of it&#8217;s hemispherical reflector.  The <span><span>radious</span></span> of the hemisphere is 5&#8243; in diameter, not far off the focal distance of my 125mm lens.  By facing my lens at the top of the hemisphere and facing my lights inwards such that their filaments are level with the picture plane,  I created a perfect band of light across the image.</p>
<p><a href="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040569_sm.jpg"><img class="alignnone size-medium wp-image-72" title="The prototype setup, lights flush with the image plane" src="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040569_sm-168x300.jpg" alt="p1040569_sm" width="168" height="300" /></a><br />
<span>I erroneously thought that I was bouncing the light across the interior of the sphere, but standing in the blast dome listening to people talk I realized that a sound generated within the hemisphere reflects along the curve of the dome, dispersing off imperfections at every point it touches.  My powder-coated reflector is doing the same thing with light.   I&#8217;m not sure of the math, but there is an inverse relation between the the source to edge distance and the number of reflections. </span><br />
<a href="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040567_sm.jpg"><img class="alignnone size-medium wp-image-73" title="my first successful test, check out that even light!" src="http://www.headfullofair.com/wp-content/uploads/2009/07/p1040567_sm-300x168.jpg" alt="my first successful test, check out that even light!" width="300" height="168" /></a></p>
