This involved a rotating drum with images that would spin around a pin in the center. I followed several tutorial Youtube videos that were based on this concept, including the one below:<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"jetpack-video-wrapper\"><iframe loading=\"lazy\" title=\"How to Make: A Spinning Lamp v. 1\" width=\"1000\" height=\"563\" src=\"https:\/\/www.youtube.com\/embed\/wwg93xSgGUQ?start=214&#038;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<p>It took me at least 2 hours of trial and error to actually get the spinning mechanism to work. This may have partly been due to the fact that everything was so haphazardly put together for a prototype. <\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"jetpack-video-wrapper\"><iframe loading=\"lazy\" title=\"spinning lantern\" width=\"1000\" height=\"563\" src=\"https:\/\/www.youtube.com\/embed\/_nOFKDT6aXg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<p>While the prototype worked, I realized 3 problems with this mechanism:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>It needed a stable set up in order to spin properly.<\/li><li>However, I envisioned the lantern to be hung in air. Would it spin without a stable base? How do I hang it so that the spinning component achieves the right balance to spin?<\/li><li>The spherical lantern shape introduced a lot of constraints for an already finicky mechanism.<\/li><\/ol>\n\n\n\n<p>The lantern shape in particular was an obstacle to work with. I decided against my original idea to paper mache a sphere to use as the moon. This is because I looked up DIY tutorials for the concept and thought that my time would be better spent working on other technical components of the project. Additionally, I didn&#8217;t see any results that particularly motivated me or stood out to me. Instead, I decided to buy white paper lanterns from Amazon that I could paint over to look like the moon. This meant that my lantern shape was predetermined. Additionally, the lantern has a wire frame inside it to keep it spherical. This wire frame added additional obstructions.  <\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/scontent-iad3-1.xx.fbcdn.net\/v\/t1.15752-9\/p1080x2048\/120277804_360213925157004_8618268481354580704_n.jpg?_nc_cat=102&amp;_nc_sid=ae9488&amp;_nc_ohc=pRzEb6bAVOEAX-IYYe9&amp;_nc_ht=scontent-iad3-1.xx&amp;tp=6&amp;oh=50bd89de716a3295f66c17cd1f3bf029&amp;oe=5F98DF03\" alt=\"\" width=\"267\" height=\"356\" \/><\/figure>\n\n\n\n<p>I decided to try projecting an image onto the lantern instead, using a spare lens that my housemate had. A light bulb would illuminate a drawing which would be projected through a lens. <\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/scontent-iad3-1.xx.fbcdn.net\/v\/t1.15752-9\/p1080x2048\/120309362_435326027439518_4546476087039054560_n.jpg?_nc_cat=101&amp;_nc_sid=ae9488&amp;_nc_ohc=hoRd5DiD76cAX-9Gfev&amp;_nc_ht=scontent-iad3-1.xx&amp;tp=6&amp;oh=a431711687894d1006e8c5c553475616&amp;oe=5F98E883\" alt=\"\" width=\"291\" height=\"388\" \/><\/figure>\n\n\n\n<p>However, the lens did not magnify the image at all.

The servo was easy to hook up and I found a sweep code online: https:\/\/www.arduino.cc\/en\/Tutorial\/LibraryExamples\/Sweep\/<\/p>\n\n\n\n<p>I attached a cutout of a man&#8217;s silhouette to the servo and put it inside the lantern. I think this effect is the one that I am happiest with and will proceed with. <\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"jetpack-video-wrapper\"><iframe loading=\"lazy\" title=\"moon lantern motor prototype\" width=\"1000\" height=\"563\" src=\"https:\/\/www.youtube.com\/embed\/lq7Bbk8YTDo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<p>My next steps for the moon lantern are to:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>Create a sturdier version of the silhouette, its attachment, and servo attachment<\/li><li>Paint the tree<\/li><li>Paint the lantern to resemble a moon<\/li><li>Conceal the wiring for the light bulb and servo<\/li><\/ol>\n\n\n\n<p>I&#8217;ve also started working on the stepping stone lanterns!
