An Australian company Sustainable Oceans International, has become the first in the world to develop artificial reefs using large construction size 3D printers.
Demand on global fish stocks, pollution, increasing ocean acidification and climate change are all making their impact on ocean life and reef systems around the world. Notable in Australia, is that the Great Barrier Reef has already lost half of its coral. As reefs provide an important home for marine life in the world’s oceans there is an increasing awareness of the need to protect these unique systems. (more…)
We all know and love Arduino, and what it has done for the rapidly growing world of DIY electronics. Yet the complexities of Arduino can be a bit much for young makers, and education enthusiast Tom Lauwers just may have the answer to harness that creativity while it is still fresh.
Heralded as a kind of “pre-Arduino”, the Hummingbird kit from Birdbrain consists of a custom controller that connects to a range of motors, sensors and lights that allow kids to build their own functional robots and more.
“…the Hummingbird controller is designed for kids who have never touched electronics or programming before.”
It’s really easy to get started making fully functional electronic devices, but don’t take our word for it. Click through to the source where Tom talks it all through in a neat clip featuring an animatronic cardboard dragon made by some 10 year old kids. Now that’s seriously fun.
LAYWOO-D3 is a wood-based 3D printing filament by inventor Kai Parthy intended for the RepRap and (possibly) similar machines. It is 40% recycled wood with binding polymers for the remainder.
3D printing with wood is remarkable enough, but this filament has the ability to mimic wood grain by varying the temperature of the print head. A temperature of 180 degrees Celcius produces a light color and 245 degrees Celcius produces a darker color. After printing, the “wood” can be cut, ground, and painted.
Unique CNC drawing machine: Is this the shape of things to come?
There is no shortage of DIY CNC and 3D printing devices, and although some do stand out from the crowd, they all tend to follow a geometry that is becoming quite familiar. Setting out to change this paradigm, Canadian techno-sculptor David Bynoe conceived of a CNC plotter that is focused around polar coordinates.
The Center Pivot Pen Plotter has only one arm that spins on a base, and moves in and out from a central point.
“It gives you a very large drawing surface with a minimum of moving parts compared to a standard x,y Cartesian plotter.”
Drawing inspiration from the notable dual polar Eggbot and Polargraph examples, David has gone one step further in simplifying the mechanism by using only a single polar coordinate system. This creates special challenges, but the code that drives the Arduino-equipped device has been written to compensate for geometric distortions. As the video after the break shows, he’s done remarkably well…
“The goal was to get it working and then worry about making it pretty, which I will get to eventually.”
In the realm of science fiction (Aliens, Halo, Iron Man, etc) exo-skeletal suits have long enabled humans to exert super human force and endure arduous conditions. But for Emma Lavelle, a young girl that was born with a condition called arthrogryposis – wearing a 3D printed external support structure is a reality to enable her to carry out everyday tasks that able bodied people would perhaps take for granted.

Arduino has arguably done more to change the DIY electronic landscape than any other open source device. We’ve often encountered this modular hardware wonder, popping up as an integral component in many 3D printers as well as being at the core of some of our favourite DIY projects.
In the trademark affable manner that he is famous for, Arduino co-founder Massimo Banzi talks through the ever-widening scope of this versatile system.
“(Arduino is) …the equivalent of sketching on paper, done with electronics”
From the humble beginnings in an Italian cafe to an incredible diversity of projects being run by all kinds of hackers, makers, enthusiasts and professionals… whether it’s the pre-teen kids tinkering in their bedrooms, high-school students sending satellites into orbit or multi-million dollar global corporations pushing the boundaries of scientific discoveries; Arduino can be found at the heart of a new revolution.
Watch this neat 15 minute TED talk overview from Massimo Banzi, on Arduino’s role in the new paradigm of Open Source Imagination.
Big ideas tend to emerge when the pressure is on, and the challenge has been set for designers from across the globe to battle it out in a 72 hour maker competition.
Celebrating the ingenuity of makers everywhere, Red Bull Creation will see twelve teams respond to an as-yet undisclosed theme in a high octane online competition. The winners will not only receive $10,000 cash for their efforts, they will also be invited to attend the 2012 Maker Faire in New York City.
Registration is now open, so if you think you’ve got what it takes… enter your details to receive the Bullduino customized Arduino board. The goal is to show your making skills by utilising this board and uploading a video of your outcome. Impress the judges for a chance to be chosen as one of the twelve finalists.
“The real action takes place while the dozen “chosen ones” work simultaneously in their own workshops, hackerspaces or homes to innovate around a common theme.”
The official competition site is a fun little journey down memory lane, with a retro OS interface that will leave you feeling like the 21st century is still decades away. Don’t let that fool you, though – there is likely to be some serious technology at hand when the contest kicks off between July 19-22.
If there’s anything Ben Heckendorn is known for, it’s his unique approach to stirring the technology pot. In a recent DIY frenzy, Ben does this quite literally as he tackles the onerous task of preparing the perfect noodle.
No longer a slave to the stove, Ben can now sit back and… relax? (well, whatever it is that Ben’s head does to unwind) while his laser-cut contraption rhythmically stirs those bubbling noodles.
Heights are fully adjustable to fit various pots and cooking utensils. There are also some neat little 3D printed pulleys that keep the stirring mechanism moving, and even a temperature probe so you can keep track of just how hot things are getting. Monitoring temperatures and controlling the movement happens via an Android app that Ben’s programming buddy Jesse put together, which communicates via Bluetooth to the Arduino-equipped pot stirrer.
Click through for Ben’s signature excitable run-down of yet another DIY technological marvel you never knew you needed.
Combine a favourite childhood boardgame with shot glasses, scale the game pieces up with a 3D printer and what do you get? 3D printed battleshots drinking game. For non-drinkers and minors 3D files for pegs are also provided so you can play a scaled up version of the traditional game. Thingiverse user xaqfu has created the full set of ships based on the classic game to download and 3D print, although as the files are .stl they are also suitable for CNC milling. (more…)
