Robot Caterpillar Tank Treads, Johnny Five Style - 3D Print 

Tomdf

When I was but a wee little inventor, I saw a movie that forever imprinted itself into my soul. This picture told the gripping tale of mans' ever loosening control over its own technology; a film that dared ask the question "What makes us alive?" This masterpiece of the cinema was, of course, Short Circuit 2.

During November of 2012 I was fortunate enough to play as an Artist in Residence at the Instructables HQ, and was given full access to a room full of Object Connex 500 multiple material 3D printers! I had always wanted a toy version of the robot from Short Circuit, Johnny Five, and I found myself with the means to print one at my fingertips. Later on I will be adding components to this robot until I have a completed, functional model.

To begin, I drew a handful of rough pencil sketches just to give myself a an idea of how the treads could work and eventually moved the idea over into 123D beta 9. A copy of the model was printed, and the pieces of track snapped together just as intended.

Parallel Leg Vise with St. Andrew's Cross 

Scotttland

  In woodworking and fabricating, a leg vise can be enormously useful.  They offer a large, flat clamping surface on which you can impart a surprising amount of clamping force.  A properly aligned leg vise can hold large workpieces such as doors or 6x6 beams.  But few companies make proper woodworking leg vises or even the hardware for them.  The issue with making a leg vise is keeping the chop (the part that moves) parallel to the bench leg when under tension.  This Instructable features a solution.

  I make all my leg vises at TechShop.

Exercício para os Tarecos! 
Cá vai esta ideia para que os vossos gatos se exercitarem, agora que chove e faz frio, e nem dá para eles saírem:

The Cats Tower 

thattori

The design concept of the cats tower is all-in-one-cage which is narrow for human being, but wide for cats. In the all-in-one-cage, cats can eat, can do exercise, can do excretion and can sleep in the cage.
Those are [1]high curiosity to environment, [2]high mobility and [3]high ability of self decision. The high curiosity to environment brings out high ability to move, and the high mobility brings out high ability of self decision. The curiosity is the path to the mobility, the mobility is the path to the self-decision. The three features are genetically pre-installed within cats, I guessed so.
Cats can't stop learning of environment. The curiosity is expressed as [1]freely exploration, [2]freely research or [3]freely strolling. It looks like action gathering information for keeping their own life.
