Visão Nocturna! E uma Pistola toda em 3D, um Sintetizador LittleBits, e o Bucanner 3D

Sim, podem ter a vossa própria instalação de Time-lapse de Visão Nocturna, cortesia da Designspark, para fins Artísticos, Científicos, ou de Segurança:


Fun with Pi NoIR and Filters

Andrew Back
 
Experimenting with the Pi NoIR prototype and blue and infrared filters.
Following on from my first attempt at building a night vision time-lapse rig, I thought I'd see how the Pi NoIR performs when used with filters. Of course, you get pretty interesting results just using the camera in daylight and without any filtering; as can be seen below images have a reddish hue and infrared reflecting plants appear curiously radiant..












Enquanto a Impressão 3D de "pistolas" em Plástico, não passa duma Curiosidade perigosa, quando são peças em Metal, e numa arma a sério, o caso muda de figura...
E pensem só: Se se pode construír uma Arma de Fogo, assim, que precisa de aguentar Pressões e Impactos terríveis, para as peças, toda a espécie de Engenhocas pode ser feita!
Invenções, em Protótipos que funcionam, mal sejam montados, Motores, Máquinas-Ferramenta super especializadas, Joalharia, e Relojoaria, Desporto, a lista é infinita!!!
Olhem só para as peçinhas, todas elas, feitas, sem nenhuma maquinagem adicional, categoria!




A fully 3D Printed Metal 1911 Pistol

It was bound to eventually happen, but I did not think it would be so soon. The company Solid Concepts has printed an entire 1911 pistol with a 3D laser metal sintering printer. What is more, the company has an FFL Manufacturing license and can print guns on behalf of customers with a five day turnaround. You provide them with a suitable CAD model and they will print it for you. This video shows their all-printed 1911 being fired …

Cadeiras, Câmaras Digitais, e Vigilância Remota

Eis uma bela duma cadeira que vocês fazem, dobrando chapa de Madeira contraplacada:


Ramified Armchair - bending plywood

alepalan

I always wanted to make a bent plywood chair so I went ahead and made this prototype. I used compression mold to curve the plywood and a water based resin glue to put the bendy ply together.

I decided to make a simple design that would be broken down into 7 different pieces:
• Front leg (x2)
• Back Leg (x2)
• Arm rest -connecting front and back leg- (x2)
• Seat

The seat is elegantly supported from the edges of the branching legs creating a bridge between the front and the back legs. The ramification of the legs not only split in two directions with the same angle to each side generating a consistent flow in the legs but also creating the armrest. The biggest design challenge was creating the partition in the legs that become part of the armchair and seat. The front legs start thick from the ground and bend forward to become the seat and also backwards to become the armrests which then come down as the back legs. The ramification was the whole concept around the project, which made it an interesting detail.

How to Make a Mini Compressed Air Turbine
fozzy13 

In case you didn't know this yet, compressed air is pretty awesome.  With simple mechanical systems - pumps - energy can be stored and used for an infinite amount of applications.  What I like about compressed air is how simple and accessible it is.  Anyone with a bike pump can start moving air to greater pressures.  Soda-pop bottles can be turned into air tanks, and by looking a little online and on Instructables, you'll find people who've used compressed air to do everything from shooting water balloons to powering a bicycle.

In this Instructable, I will show how I made a miniature compressed air turbine. 










Isto não é só importantíssimo para os Deficientes Físicos, porque pode ser feito por vós mesmos, como pode servir para quando precisam de mais uma mão, para segurar em algo, quando estão a trabalhar, e não há ninguém... Á mão!
E o que dizer de tarefas demasiado perigosas para lá arriscar os dedos?
Altamente útil e meritório.




DIY Prosthetic Hand & Forearm (Voice Controlled)

Mizchief100
Do you live with only one hand, or ever feel two just isn't enough? Well now you can make another! This project combines two very cool things: an arduino voice recognition shield and an open-source 3D printed robotics project called InMoov. Basically what I've done is modify the InMoov hand/forearm to be usable as a prosthetic (or additional appendage) and add a VR (voice recognition) shield to receive verbal commands and then make corresponding motions with the hand. The advantage of voice control is that it doesn't require muscles and is more flexible to different physical conditions (also hands free!). My program includes 15 general hand gestures and actions for everyday living! When I was looking into myoelectric arms kept thinking that the functionality wasn't worth the thousands of dollars. While mine isn't as fancy as some it's remarkable what you can create with desktop 3D printers, an arduino, and servos!

Autonomous quadcopter uses a smartphone as its brains

Ben Coxworth

With one possible exception, autonomous quadcopters are not something that you would expect to be inexpensive. A relatively cheap model may indeed be on its way, however. Designed by the Vienna University of Technology’s Virtual Reality Team, the tiny aircraft utilizes the processor and camera of an off-the-shelf smartphone.
The Vienna team, led by chief engineer Annette Mossel, programmed the quadcopter’s navigation software into the processor using an app.
Once in flight, the UAV uses the phone’s camera to identify QR-like coded squares placed on the floor within a room. These allow it to create a map of the room, so it can subsequently find its way around the space on its own. Ultimately, plans call for it to be able to identify actual objects naturally present in a room (such as tables and chairs) using a Kinect-style depth sensor, and create its map using those.

Noticias incríveis!

Como voltar à vida, depois de Congelar:

Yeast and worms can survive hypothermia if they are first subjected to extreme oxygen deprivation, a new study finds.
The results could explain a long-held mystery as to how humans can be brought back to life after "freezing to death," the scientists say.
The study uncovered a previously unknown ability of organisms to survive lethal cold by temporarily slowing the biological processes that maintain life. 

"We have found that extension of survival limits in the cold is possible if oxygen consumption is first diminished," said researcher Mark B. Roth of Fred Hutchinson Cancer Research Center in Seattle, Wash.
One form of "forced hibernation," the behavior known as "suspended animation," literally involves the sudden halting of chemical reactions in the body due to the lack of oxygen. A 10-hour time lapse video of a garden worm embryo in the process of developing into a full-fledged baby worm showed a rapid process of cell division freeze to a stop upon the environment’s oxygen removal. That same cell division resumed unaffected two and a half hours after oxygen was restored.

Watching grass grow is way more interesting than you think. In an effort to understand cellular development in plants, a team of French scientists made a surprisingly exciting video animation of grass growing at the cellular scale.
The team stained growth cells in Arabadopsis thaliana and rice plants, and trained laser-scanning microscopes on the growing plants, according to Scientific American. They fed the microscope data into new computer algorithms that reassembled the structures, cell by cell, in three dimensions. The result is this video.

Que tal um novo Metamaterial que vai fazer este Avião, Indetectável?
A New Engineered Stealth Metamaterial is the Blackest Ever
By Rebecca Boyle

A new blacker-than-black metamaterial absorbs almost all the light that hits it, heralding a new breed of stealth technology.
The material's internal structure absorbs almost all the electromagnetic radiation in a particular range, New Scientist reports. Ordinary black objects, by contrast, always reflect a bit of light. The material could be applied to all parts of the electromagnetic spectrum, meaning it could be used to make materials invisible to radar.
Designed by Evgenii Narimanov of Purdue University, Mikhail Noginov of Norfolk State University in Virginia and their colleagues, the material consists of silver nanowires embedded in very thin 0.4-inch aluminum oxide squares. Their array-like structure gives them their unusual properties, New Scientist says.

Man-made metamaterials can also bend light to create invisibility cloaks, ultra-thin sound-proof walls and even miniature Big Bangs and megaverses.

The researchers tested their new black material with near-infrared radiation, just beyond the red end of the visible spectrum. When the radiation hit the polished material at less than 45 degrees from perpendicular, about 20 percent of the radiation bounced off. When they roughened the material so it wasn't smooth, less than 1 percent of the radiation bounced off.

Narimanov told New Scientist the technology would likely be used to build radar-proof stealth equipment.

Wow! Jets Punch Holes in Clouds and Create Rain
By LiveScience Staff
posted: 14 June 2010 12:21 pm ET
Aircraft can accidentally punch holes in clouds, leaving a trail of snow or rain in their wake, a new study finds.

Turboprop and jet aircraft that climb or descend under certain atmospheric conditions can inadvertently trigger what's known as cloud seeding. This technology is usually associated with schemes to control the weather. However, cloud seeding can happen by accident as planes soaring through mid-level clouds leave behind odd-shaped holes or channels in the clouds and cause narrow bands of snow or rain to develop and fall to the ground.

Holes punched in clouds are a phenomenon that has been recognized for many years and seen in photos from around the world. A front-page feature on Yahoo! carried the headline "A Halo over Moscow" after photos emerged of just such a hole in October 2009.

The secret behind these mysterious clouds has now been revealed: Supercooled water droplets that remain liquid even at subfreezing temperatures — below about 5 degrees Fahrenheit (minus 15 degrees Celsius). When an airplane cuts through clouds containing the supercooled water droplets, air is cooled behind aircraft propellers or over jet wings, and these water droplets freeze and drop toward Earth.
