The idea is to build a single &#8220;engine&#8221; out of cork and wire (possibly a wire clip since they are easy to find) that can be moved back and forth between different contraptions. Building a single one also saves some time during a workshop. <\/p>\n\n\n\n<p>The models can be built out of simple 3&#8243; by 5&#8243; index cards. And it&#8217;s nice to use the ones with a grid although they are less common. The grid makes it easy to mark the cuts and bends. The card itself also gives you a platform that can be pressed down with the cork when you are rotating the crank. Here are 3 models:<\/p>\n\n\n\n<p>The first one is simply about turning rotary motion into reciprocating motion, notice how the wire fits into a long slit into the paper:<\/p>\n\n\n\n<div class=\"wp-block-image is-style-default\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/wolfcatworkshop.com\/otherfiles\/simpleCardModel-3.gif?resize=400%2C400&#038;ssl=1\" alt=\"\" width=\"400\" height=\"400\" data-recalc-dims=\"1\" \/><\/figure><\/div>\n\n\n\n<p>The second one is about how expressive paper can be with no straight creases, looks like a worm \ud83e\udeb1<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/wolfcatworkshop.com\/otherfiles\/simpleCardModel-2.gif?resize=400%2C400&#038;ssl=1\" alt=\"\" width=\"400\" height=\"400\" data-recalc-dims=\"1\" \/><\/figure><\/div>\n\n\n\n<p>And this one is about building a simple 4-arm linkage out of paper using a basic pop-up technique<\/p>\n\n\n\n<div class=\"wp-block-image is-style-default\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/wolfcatworkshop.com\/otherfiles\/simpleCardModel-4.gif?resize=400%2C400&#038;ssl=1\" alt=\"\" width=\"400\" height=\"400\" data-recalc-dims=\"1\" \/><\/figure><\/div>\n\n\n\n<p>A little wire bending can yield the next level of complexity with two alternating arms:<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/i0.wp.com\/wolfcatworkshop.com\/otherfiles\/simpleCardModel-1.gif?resize=400%2C400&#038;ssl=1\" alt=\"\" width=\"400\" height=\"400\" data-recalc-dims=\"1\" \/><\/figure><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I was asked to do and online workshop and I came up with an idea for introducing beginners to making moving things.
