Fowl accommodations provided by mathematics

[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?

Mouse runs through VR maze

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.

Haptic Halluc 2

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?
