I and WenChing started to pick up some trash from the 4<sup>th<\/sup> floor of 66 W building. We found an apple desktop and a power supply. We dismantled it and unfortunately, it didn\u2019t work. What we could have done, since we had only a few fans and a power supply, was just to make it as simple as we could as the name of an assignment, \u2018Low Tech\u2019. We came up with an idea of using ping-pong balls and fans to make those balls to move and trigger a circuit. We made some ramps and tied two wires with a fan, connecting with a stepper motor, and wrapped all balls with foil. In the beginning of the movement balls would move down from a ramp by letting two wires, connecting with a stepper motor\u2019 open. Then those balls would make the circuit close to trigger the last fan to blow a piece of paper\u00a0with a word \u2018BRAVO\u2019.<\/p>\n<p><a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-4.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1123\" src=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-4-1024x764.jpg\" alt=\"\" width=\"590\" height=\"440\" srcset=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-4-1024x764.jpg 1024w, http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-4-300x224.jpg 300w\" sizes=\"auto, (max-width: 590px) 100vw, 590px\" \/><\/a><\/p>\n<p>Ramp test<\/p>\n<p><a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/balls-test-poster.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-1116\" src=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/balls-test-poster-170x300.jpg\" alt=\"\" width=\"170\" height=\"300\" srcset=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/balls-test-poster-170x300.jpg 170w, http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/balls-test-poster.jpg 272w\" sizes=\"auto, (max-width: 170px) 100vw, 170px\" \/><\/a>\u00a0 \u00a0 \u00a0<a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/balls-test.mp4\">balls test<\/a><\/p>\n<p><a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1106\" src=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-1-1024x570.jpg\" alt=\"\" width=\"590\" height=\"328\" srcset=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-1-1024x570.jpg 1024w, http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/photo-1-300x167.jpg 300w\" sizes=\"auto, (max-width: 590px) 100vw, 590px\" \/><\/a><\/p>\n<p>Balls VDO<\/p>\n<p><a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/Balls-VDO-poster.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-1117\" src=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/Balls-VDO-poster-300x169.jpg\" alt=\"\" width=\"300\" height=\"169\" srcset=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/Balls-VDO-poster-300x169.jpg 300w, http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/Balls-VDO-poster.jpg 568w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>\u00a0<a href=\"http:\/\/www.collab.scrapyardchallenge.com\/wp-content\/uploads\/2011\/12\/Balls-VDO1.mp4\">Balls VDO<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Assignment 1: Low Tech \/ Rube Goldberg Machine Balls by Parinot and WenChing Around two weeks before the presentation, we started a new project with a new group.
