A Ray Gun à venda, um Quadracóptero para o Povo, um Robot Escavador, e Raios Tractores!

Depois dalguns percalços, eis outra vez a Ray Gun à venda, e desculpem o Mau-jeito... 

Ray Gun, tried and tested

A hommage to all those cool Sci-Fi movies, a Fluorescent Acrylic Ray Gun, with place for Electronics on the box, and a hole trough the Barrel, to place the Laser Pointer, LED, whatever.
You can use a Rubber Band as the Trigger spling, and it will also hold the back lid in place!

Não acertam com as Fotos? Este Quadracóptero faz o trabalho, e até vos segue, enquanto andam, por aí!

A US$49 personal autonomous micro UAV?

Ben Coxworth

Imagine if you had your own tiny quadrotor unmanned aerial vehicle (UAV) that you could control with your voice, that would automatically follow you while avoiding obstacles, and that could shoot and stream video of you using an onboard camera. Now imagine that you paid less than 50 bucks for it. Well, if the hype is to be believed, that’s just what tech firm Always Innovating is promising with its MeCam.


A Corrida aos Minerais do Espaço já começou, agora, é a Nasa, a entrar com esta Escavadora-Robot para minerar pelo Sistema Solar...

NASA working on RASSOR robot space excavator

Jason Falconer

Recently we've seen preliminary asteroid mining plans from Planetary Resources and Deep Space Industries, but what about NASA? The government agency would like to do some excavating on the Moon, Mars, and asteroids, too – but it isn't in it for the profit. NASA wants to clear the way for construction projects and mine materials for use by astronauts, and is developing a teleoperated robot called the Regolith Advanced Surface Systems Operations Robot (RASSOR, pronounced "razor") to get the job done.


Lembram-se dos Raios Tractores, da Ficção Científica? Pois os Cientistas estão a utilizar a Luz Laser, para começar a fazer algo de real, com esse conceito, agora:

Scientists turn light into a tractor beam

David Szondy
From The Skylark of Space to Star Wars, no self-respecting science fiction spaceship would break orbit without a tractor beam on board. We’re still a long way from locking on to errant shuttlecraft, but a team led by Dr. Tomas Cizmar, Research Fellow in the School of Medicine at the University of St. Andrews, Scotland, has turned a laser into a tractor beam that works on the microscopic level.
Tractor beams are one of those things that seem on the far edge of what’s possible. The idea of a beam of energy streaming out that pulls things in is counter-intuitive, but scientists have been developing things that work like tractor beams since the 1960s and light manipulation has been tried since the 1970s.
