Borracha Condutora, Moldes em Silicone, e um Catrapázio Voador

Como fazer borracha condutora de Elctricidade, para "pele" sensível ao toque para os vossos Robots, etc. 


A Borracha...

...E como funciona, que é o mesmo que dizer, como tem "tacto":

Conductive Rubber: Make Touch Sensitive Robot Skin

Make conductive rubber and use it to create a flexible touch sensitive robot skin. The resulting skin can be stretched across a frame or mounted on solid surfaces. It can also be mounted on curved surfaces or clothing.
It is touch sensitive and will produce an electrical signal no matter where you press on it.

Simples, é bom, eis uma maneira super-simples de fazer Moldes em Silicone:

World's easiest silicone mold.

Yep. That's right. I am about to change your mold-making technique forever. This simple way of silicone mold-making will have you wanting to make casts of all your trinkets and toys.

You will need:

• water
• blue dish-soap (any brand seems to work)
• silicone caulking (do not buy quick set silicone, you need 100% silicone)
• bowl
• caulking gun
• something you want to make a mold of.
• scissors/knife
• masking tape - to patch holes in your positive, if necessary.

Festo's SmartInversion flying contraption turns itself inside out for propulsion

By Jan Belezina 

Festo, a German automation technology company that brought us, among other things, the smartbird robotic seagull and bionic flying penguins, has built a flying object unlike any we have seen. Despite the impressive biomimicry track record, this time its engineers decided to look for inspiration in the inanimate world of geometry. Based on a geometrical band first created by Swiss artist and inventor Paul Schatz, the SmartInversion is filled with helium and propels itself through the air by constantly turning itself inside out. By investigating this pulsating, rhythmical movement, called inversion, the company hopes to identify possible uses for it in technology.
