SpaceShipTwo to be fueled by thermoset plastic similar to nylon

David Szondy

As the still-to-be-announced date of the first commercial flight of Virgin Galactic’s SpaceShipTwo approaches, more and more of the technology involved is getting nailed down. A case in point is the company's announcement that it has decided which fuel will be used in the first passenger-carrying flights of the suborbital spacecraft. The solid fuel grains that will fuel the world’s largest operational hybrid rocket will be a thermoset plastic similar to nylon.

Introducing PETBOT: A node.js Telepresence Robot

Ari Rizzitano

Recently we added a new member to our engineering team. This is PETBOT, aka Providence Engineering Telepresence roBOT.

It’s a telepresence robot I built for our office, consisting of an iPad mounted on a lightweight chassis powered by an RC car. To operate it, you open up a video chat session with the iPad, then control the robot from your browser using the web interface.

PETBOT can see, move, talk, and, like any startup employee, play foosball. Or at least try to.

Material Monday: i.materialise for all your titanium 3D prints!

Tatiana

Are you looking for a strong and super light material? i.materialise is one of the few online 3D printing services to 3D print your design in titanium. Read all about it!

Titanium is great for jewelry and light weight parts that need to be very strong. When we launched it, almost three years ago, we didn’t quite know what you would do with this technology. But you’ve amazed us with a lot of incredible designs.We’ve seen bike parts, rings, eyewear, earrings (you cannot have any allergic reactions from it), accessories,….you name it. At this stage, titanium is still the strongest material to 3D print in.

Stainless magnesium breakthrough bodes well for manufacturing industries

Brian Dodson

Magnesium alloys are very attractive for a range of weight-sensitive applications. They have the largest strength-to-weight ratio of the common structural metals, are lighter than aluminum and are particularly favored for being easy to machine and for their ability to be die cast to net shape. Unfortunately, magnesium alloys tend to corrode too easily. A team at Monash University in Australia has now discovered a novel and potentially game-changing approach to the problem: poisoning the chemical reactions leading to corrosion of magnesium alloys by adding a dash of arsenic to the recipe.
Magnesium alloys are of great interest as lightweight replacements for aluminum, titanium, and steel components in a range of transportation and aerospace applications. However, such alloys corrode easily, and this often prevents their use as replacements for noncorroding metals, particularly in applications requiring high reliability over a range of environments.

Zeoform: The eco-friendly building material of the future?

Antonio Pasolini

Australian company Zeo has developed and patented a glue-fee process that creates a strong, versatile new building material out of just cellulose and water. The resulting hardwood-like material known as Zeoform can then be sprayed, molded or shaped into a range of products. And it's not just trees that stand to benefit – Zeoform also promises an eco-friendly alternative to the use of plastics and resins.
...
Zeo says the resulting material that is recyclable, "as strong as ebony" and can be shaped using a range of techniques that make it suitable for use in "any industry requiring woods, plastics and resins for manufacturing." At higher densities, Zeoform is water- and fire-resistant and the company is also working on coatings that could resist some of the most extreme weather conditions.

Make a UAV for research and photography

McMagical Engineer

You, yes you, can build and fly a personal UAV. Read this and see how!
If you like this instructable, consider voting for me in the RC contest.

I remember riding in the car when I was little, watching the shadow of our car float over the ground beyond the guard rail. I would imagine that the shadow was from a plane and would think about what it would be like to see the journey from the air. What if I had a little plane that I could fly from the car and explore the areas just behind the trees. What if I could launch a plane on a hike, and see the far peak on the other side of the glacier, or take a video of myself and friends waving from the top of a mountain?
These days, I live near the ocean and wonder what it would be like to capture video of sailboat races, darting in and out of the masts like the seagull scene in "Finding Nemo." What about a video of whales from the air? To see what the seagulls see as they float over the water, under massive bridges and over tiny islands...

Then I found FPV UAVs and the dream became a reality.
This instructable will walk through your my first FPV UAV, teach you how to get started, how to make one, how to fly one, and introduce modifications you can make as you dive deeper into the sport.

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.

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.

4 Easy Steps to Creating a Unique Wine Bottle Lamp 

KentM

Making a table lamp from a wine (or any type of) bottle seems to be a very popular craft project. However, while the lamps I saw online were OK, I always considered them little more than a novelty item.  That's when I decided to take a crack at designing one myself. And, after I made my first wine bottle lamp, friends and family began asking me to make lamps for them or to give as gifts. For that reason, I decided to create this instructable and share my four easy steps on how to make a wine bottle lamp that will be as distinctive and unique as the person who creates it.

Vibromag Cable detects intruders using the Earth's magnetic fields

Ben Coxworth

Things might be getting a little more difficult for the James Bonds and Jason Bournes of the world. A new system developed by Prof. Uwe Hartmann at Germany’s Saarland University utilizes the Earth’s magnetic fields to instantly determine when and where a security fence has been breached.

The technology is known as the Vibromag Cable, and incorporates a long cable containing regularly-spaced magnetometer probes. That cable is permanently or temporarily added to an existing metal fence, or it can be buried in the ground underneath one.

Turn Empty Water Bottles Into Alcohol Fueled Rockets 

NightHawkInLight

Not long ago I was challenged to create a project using a water bottle that could be displayed in a one minute long video. While I missed the one minute mark, I think I still managed to make a pretty entertaining device.

The rocket and launcher featured in the above video function off of a very simple concept of igniting a flammable vapor using a replacement barbecue igniter to propel the bottle through the air. The parts for this project should cost no more than $15, with the igniter taking up the majority of that price tag at about $10. The bottles can be reused many times until the heat from repeated shots eventually warps the plastic.

Global Village Construction Set
Another wildly successful Kickstarter campaign: 10 days still remaining

We first came across Marcin Jakubowski’s incredible Global Village Construction Set (GVCS) back in April, following his well-received TED presentation. The concept of GVCS is one of those super-simple, too-good-to-be-true proposals that has real potential to change so many lives.

What is it all about? Imagine a modular, DIY, low-cost, open source, high-performance platform. One that makes it easy to fabricate all of the 50 different industrial machines that it takes to build a small, sustainable civilization complete with modern comforts.

The aim of the GVCS is to lower the barriers to entry into farming, building, and manufacturing. Its a life-size lego set that can create entire economies…

Like all good farmers, Marcin and the guys from Open Source Ecology have certainly been busy.

Opening their project to the hands of the public with a highly successful Kickstarter campaign, things are looking good for the first set of prototypes that have been developed.

Click through for more information about the campaign, as well as a deeper look at the Global Village Construction Set.

earthCell batteries promise near-zero waste and better value


By Ben Coxworth

If you really want to minimize the amount of toxins that you put into the environment, use rechargeable batteries. Disposable and rechargeable batteries can contain heavy metals such as mercury, lead, and cadmium, and with an estimated 3 billion batteries a year being discarded in the U.S. alone, the sometimes small amounts in each battery can really add up. Using rechargeables greatly reduces the number of batteries entering landfills, but many people don't bother buying them, or the chargers that they require. That's where earthCell batteries come in. They can be used like disposables, except that users send them away for for recharging or recycling when they're dead.

earthCells are low self-discharge nickel metal hydride (LSD NiMH) batteries, which among other things are claimed to have a much longer shelf life than regular NiMH batteries, and longer run times than alkalines. When a customer's earthCells do expire, they put them in a prepaid mailer. Once that mailer is full, the customer sends it off to the company.

Video: A Steerable Remote 'Telexistence' Robot that Transmits Sight, Sound, and Touch to the Operator


By Clay Dillow

Keio University researchers are taking telepresence to the next logical level with a new “telexistence” robot called TELESAR V, a robotic platform that doesn’t just transport the user's eyes to another location, but also his or her ears and hands as well. The idea is to break through the limitations of time and space to allow a user to actually feel like he or she is present elsewhere via a remotely operated robot that returns three sensory stimuli back to the user.

Using a head-mounted 3-D visual display, an audio system that streams sound to the user, and tactile gloves that allow the user to feel the shapes and temperatures of objects--currently the robots force vector and temp sensors can accurately relay textures as fine as the unevenness on the surface of a Lego block--the user can manipulate the robot remotely and feel what the robot feels. The designers are looking for a true avatar sensation, one that makes the user really feel that he or she is inhabiting the place of the robot.
