Papercraft Strandbeest Is A Great Rainy Day Project

Here in the Midwest it sometimes seems like Spring will never, well…spring. We get that “April showers bring May flowers”, but nearly all of the last month has been cold and rainy around these parts. While things are improving, we think it’s always good practice to have a few fun projects at the ready, just in case your plans with the kids get rained out.

We think that Hackaday reader [Dombeef’s] papercraft strandbeest is a perfect idea for a rainy afternoon. The supply list is pretty short, requiring little more than some scissors, pliers, paperclips, and glue in addition to the thick paper that makes up the body of the strandbeest. The paper is cut into pieces according to the PDF template he includes in his Instructable, secured to one another via small pieces of paperclip.

Once the legs are all constructed, a main axis is built from one of the remaining paperclips, and everything is joined together under the main portion of the strandbeest’s body.

As you can see in the video, the legs work quite well, though the strandbeest can probably benefit from a hand crank in the short term. [Dombeef] plans on adding a small motor to his creation, which should get the strandbeest moving about quite rapidly once completed.

If you are looking for more fun projects to do with the kids, look no further than this papercraft gyroscope or these squishy circuits.

Hamster Powered Strandbeest

Gakken magazine featured a miniature wind-powered Strandbeest recently, converting it to run on everything from rubber bands to solar power. [Crabfu] thought it would be worthwhile to hack the Strandbeest kit that shipped with the magazine as well, so he started to brainstorm.  Well-known for his steam powered hacks previously featured here, he did originally consider adding a steam plant to the walker.  In the end, he scrapped that idea due to concerns about heat and weight.  Thinking about it further he settled on something he considered ridiculous, even stupid: A hamster powered Strandbeest.

[Crabfu] added a few components including a hamster ball and a simple chain drive from a Meccano building set before testing the device with a toy train as the power source.  Once he was certain that he had the proper gear ratio set, in went a friend’s hamster.  The device worked wonderfully, much to the delight of his nieces, as you can see in the video on his site.

Theo Jansen: Like The Professor From Gilligan

[Theo Jansen] is building lifeforms that will live and thrive on the beach. He calls them StrandBeest and uses PVC electrical conduit, plastic tubing, and lemonade bottles as building material. The many-legged creations are amazingly advanced, able to count steps, sense and flee from the water’s edge, and protect themselves from high wind. He gave a TED talk back in 2007 that we’ve embedded after the break; it’s uncanny. See examples of his creations using fans and sails to store wind energy as compressed air in the lemonade bottles, then use that pressure for locomotion. He also demonstrates a binary step counter and water sensor. Continue reading “Theo Jansen: Like The Professor From Gilligan”
