The Humble Velocipede
This project will only be funded if at least $10,000 is pledged by Thursday Aug 16, 3:00am EDT.


The Humble Velocipede is a small-scale evolution of Theo Jansen'sStrandbeest (http://www.strandbeest.com/) kinetic sculpture. This meditative toy is designed to scuttle over countertops and coffee tables. Its stride is human powered, but the Velocipede really holds its own on shallow inclines.
This project started when we built a life-size plywood Strandbeest (http://www.theatlantic.com/video/index/244521/). The big machine was gorgeous, but bulky and inconvenient to transport. Curious about what it would look like as a toy, we built one just for fun. It turned out better than any of us expected, so we refined our design for production. Instead of shrinking down Jansen's original, we recast that organic appeal for a domestic space. We think we've made a playful desktop sprite that is as captivating around the house as Jansen's are on the beach.
The walking mechanism behind the toy is inherently complex. With production in mind, we made our design as simple as possible. At the heart of the machine is the crankshaft, which is responsible for coordinating the leg movement. The crankshaft is made from a single steel rod bent into a resilient spine around which the whole toy is built.

The bamboo legs are composed exclusively of triangles and rectangles in order to minimize material waste and maximize production speed. This allows us to tile them efficiently by overlapping cutting paths and eliminating dead space. Once the legs are made, the centrality of the crankshaft allows us to quickly thread the toy together.
What's the money for?Bamboo is beautiful, but expensive. We need to buy it in bulk, and if successful we'll use the majority of our funding to make our first minimum order. The remainder will go towards additional materials such as dowel pins, washers, sandpaper, woodfinish, and packaging.
Rewards!For all donations of $1 or more we will add your name to a list of supporters and bury it in a secret location, deep in the earth.
If you give between $10 - $24, we'll send you a bundle of 5 high quality postcards. Our friend and photographer Mercy McNab took these lovely photographs of the Humble Velocipede hitting the town.

If you give between $25 - $49, you'll receive one of our two t-shirts. One shows an icy cartoon of the toy, and the other is a wire-frame diagram of the walking mechanism in action. They're American Apparel men's cut shirts in heather black (we'll get your choice and size upon order). Check out the designs below.

For donations between $50 - $99, you'll get a unique wall hanging cut from our "spoil board," inspired by a post we saw on MAKE (http://blog.makezine.com/2012/06/07/cnc-spoil-board-art/). We'll cut these into wall hangings from finished 1/4" bamboo ply. To give you a sense of how toolpaths look, below is a closeup of the tracks left in our plywood spoil board from early prototyping.

This one looks like fun.

Only a few hundred dollars away from the $10,000 goal, with plenty of time left. Could be a real winner.
