In case you’ve been living under a rock for a few weeks, we’re giving away a trip to space for the best, most grandiose connected hardware project. [coxrandy], a.k.a. [Phillip Cox] realized the best way to build something awesome was to think big, and his plan for building a 1km dome (yes, 1000 meters) is the most ambitious project we’ve ever seen.
The BuckyBot, as [Phil] is calling his build, relies on the ideas of the great [Buckmister Fuller] and his idea to build a huge geodesic dome covering all midtown Manhattan. [Fuller] didn’t have the resources to build a structure this large in the 1950s, and to be honest, we don’t have the resources to build it now. It would be a ludicrous effort to build something like this one beam at a time, and [Phil] concludes that to build something this big, we need to think small.
Instead of thousand ton cranes and several thousand vehicles trucking in building supplies, [Phil]’s idea uses small “BuckyBots” – a combination 3D printer and robot – that builds one structural cell of a giant dome at a time. These BuckyBots climb around the structure, build the internal and support structure, slowly climbing to the skies on their fractal-inspired creation.
The Hackaday Prize contest will end far before [Phil]’s BuckyBots will have the ability to build a kilometer-wide dome, so the current plans are to modify his RepRap Mendel to crawl. Once that’s done, he’ll have his newly built BuckyBot build a 2 meter hemisphere in his garage. From there, construction moves to the back yard where a 10 meter dome will be built.
Even if this project never makes it past the planning stages, it’s an awesome example of thinking big, something you’re going to need if you’re trying to win a trip to space.
[Anthony’s] chickens happily return to roost each night thanks to the spacious house he built for them. Sadly the geodesic dome never became the home of the future despite what the people were promised. But using a bit of unorthodox joinery you can create enclosures for your chickens or other animals in need of shelter.
The construction begins with 30 isosceles triangles and nine equilateral triangles which he cut from solid wood on a chop saw. To join the pieces he used metal banding and screws, which hold the edges close together but allow them to flex. This solved the problem of precision mitres at the edge of each wood piece. Once the dome was fully assembled he filled the joints with caulk and finished it with rubber roofing compound.
Our only question is: how’s he going to automate the door of the coop?
In an effort to determine the brain of animals during movement, scientists have built this contraption. It is a VR pod for a mouse. While we’re pretty sure/hopeful that none of you need a mouse VR system, we think the rig is interesting enough to stand on its own. It appears to be a convex mirror setup, projected in a dome. The controller is interesting in that it looks like a giant trackball hack. They’re using an optical mouse rigged to a ball floating on a cushion of air. This makes it much easier for the mouse to move. There’s a video of the whole thing in action after the break.

We can not express the childlike glee that we experienced watching this video. We want so badly to have one of these setups. What you are seeing is a half dome projected cockpit with two haptic controllers in the style of a delta robot. This is controlling the Halluc robot which is a hybrid wheeled octopod. The dome can and has been done at home fairly simply, and we suspect that you guys could come up with some similar delta controllers. So who wants to build one and donate it to hackaday?
