Nice stuff! I'd love to have some of my work as physical models but I've never had anything worth the cost of printing.

As for mocap, I'd be interested to see how those suits compare to the $100 or so Kinect solution for accuracy;

That's pretty cool stuff! However, it's a big difference with an actual mocap suit.
The mocap suit consists of the suit itself, which is just sort of a wetsuit, and you can put the modules that track the movement in a kind of 'pockets' as well as the cables connecting the modules. On the back there are two batteries sending a wireless signal to two receivers triangulating the position of the modules.

So the biggest difference is the size of the field it records, for example I recorded an animation of a guy sprinting for twenty meters and all the motion data was still transferred.
Also with the kinect solution it won't track what isn't visible, so animating with your back facing the camera won't work.
There might be other differences, but I haven't worked with kinect for motion capture, so I'm not sure. I do own a kinect however, might try it out sometime!

This sounds exciting;

In somewhat relation to the threads title;

We can now trap anti-matter for 15minutes. Efficiancy is low, but this certainly is encouraging for the possibility of one day havesting the stuff in orbit.

This is less high tech, and more a genius new low-tech invention;
http://hackaday.com/2011/07/28/3d-pr...rive-platform/

Its basicly, umm...reinvented the wheel :P

Essentialy its a way to steer a vechile without ever slowing the drive wheel down....incredibly manavourable and completely different to how we normaly picture "cars" working.
The roundish wheel actualy rotates horizontaly, and the angle it touchs the ground determains direction...letting the one wheel move provided movement in all 4 directions.

Streg 2011-07-30 02:07

sweet! now imagine one of these with that same set of wheels! :P

Darkflame 2011-07-30 03:56

Yeah...probably stupidly dangerious, but that would be a hell of a vechile. :p

Curiously the guy wants to make one that purely has one of these...umm..."wheels" and nothing else....using Segway like balancing technology.

This idea was obvious to me as soon as the Dyson-ball vacuum cleaner came out. :p

But thats no closer to this then a bullpoint pen is :p

difference being Dyson had a TV advert which showed off manoeuvrability

The chips can also "learn" how to complete each task if trained.


Darkflame 2011-08-20 21:50

Cool...allthough natural networks have been able to do the same thing before I think, but to have it on a chip is a significant step forward.

Also, bah, HP actualy made good tablets. Proper ones you could do stuff with.

Neutrinos measured at a speed higher than c. Here's the details.

Yeah, weird stuff.
If correct I guess all we can do is make c higher then the speed of light?

:p

Darkflame 2011-09-25 13:24

Basicly thats the most likely.
It could also imply that light has mass.

Virgin Gallactics Spaceport has been finnished;

Well, judgeing by the image "finnished" is relative, guess it will look better after the building stuff is cleared and the greenary grows a bit...

Kobold 2011-10-18 19:57

Quantum Levitation. :)

Darkflame 2011-10-18 20:07

Seen the effect before, but thats by far the coolest demo of it I have seen.

Some of the related videos are cool too - one of them has two things levitating above eachother.

This is all why we need room temperature superconductors!

Streg 2011-10-25 21:52

that's almost unbelievable :|

xesf 2011-10-25 22:41

This just reminds me Back to the Future hover skateboarding :)

Jasiek 2011-10-28 11:41

There's vids of a live frog, or strawberries levitated in a strong magnetic field. Wicked.

Jast 2011-11-05 10:43

I haven't seen this quantum levitation thing before, brilliant stuff! Reminds me of Maglev trains :D
