Then I thought of ripple tanks for physics experiments, but all of the ones on amazon and ebay come with vibrating wave makers which make them expensive. Then I found some youtube videos of how to make your own aquarium from Plexiglas and special solvent cement. This seems cheapest and not too hard. Maybe I can figure out how to laser cut the Plexiglas \u2013 I see robotics majors do it all the time.<\/p>\n<p>I first pictured the light sources as spotlights. However, these must be far from the subject to create hard shadows. I needed a point source such as a very bright LED. I needed to find an unusually bright LED to experiment with, so I took apart my alarm clock (see below) and used the one inside.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-448\" src=\"http:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock1-300x142.jpg\" alt=\"alarm clock1\" width=\"300\" height=\"142\" srcset=\"https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock1-300x142.jpg 300w, https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock1.jpg 478w\" sizes=\"(max-width: 300px) 85vw, 300px\" \/>\u00a0<img decoding=\"async\" loading=\"lazy\" class=\"alignnone  wp-image-452\" src=\"http:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock-2-1-300x290.jpg\" alt=\"alarm clock 2\" width=\"246\" height=\"238\" srcset=\"https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock-2-1-300x290.jpg 300w, https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock-2-1-768x743.jpg 768w, https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock-2-1-1024x991.jpg 1024w, https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/alarm-clock-2-1-1200x1161.jpg 1200w\" sizes=\"(max-width: 246px) 85vw, 246px\" \/><\/p>\n<p>It created very crisp shadows, unlike my desk lamp.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-453\" src=\"http:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/hard-shadow-300x174.jpg\" alt=\"hard shadow\" width=\"300\" height=\"174\" srcset=\"https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/hard-shadow-300x174.jpg 300w, https:\/\/www.joshuarosenstock.com\/teaching\/lightart_D16\/wp-content\/uploads\/2016\/04\/hard-shadow.jpg 398w\" sizes=\"(max-width: 300px) 85vw, 300px\" \/><\/p>\n<p>I was worried about finding the exact red and exact cyan that would be compatible with the 3D glasses. I came up with a clever solution: just use white LEDs and filter the color with a second pair of 3D glasses. I then ordered some white 10 lumen LED\u2019s (which is apparently very bright) from a website called superbrightleds.com. Aptly named!<\/p>\n<p>Finally I thought about the frame or scaffolding. I have seen reusable metal prototyping channels, called 80 20, used in several MQP\u2019s and at my summer job. They would be ideal, but unfortunately it would cost about $70 for the amount I want. A cheaper alternative is to make something structural out of cardboard. While it sounds like a weak material, it can be quite sturdy when there is enough of it. Prof. Rosenstock suggested PVC which I think is a great idea.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Progress Report 1 I started thinking about materials and implementation.
