Nick Thatcher built this self-balancing unicycle using an Arduino UNO, a IMU (gyroscope) from Sparkfun, a 24v 350w geared motor, a wheelbarrow wheel, and a handful of other basic parts.
The IMU senses when the unicycle tilts too far forward or backward, the Arduino does some calculations, and then the motor compensates. The rider still has to put a little effort into maintaining balance (and not falling sideways), but it wouldn’t be much fun if the Arduino did all the work.
Easily find software for your Raspberry Pi or offer your own creations.
The Rasberry Pi foundation has launched the Pi Store, a one stop shop for software, tutorials, games, and useful code for the Raspberry Pi. The idea is to provide an easy way to to find great software and distribute your own, thus making it even easier to get started. At launch, the store had 23 free titles and 1 paid, commercial program, so the venue is definitely favoring free sharing, at last so far.
NASA has commissioned Dr. Amit Bandyopadhyay from Washington State University and group of colleagues to test the feasibility of 3D printing using moon rock as the build material. Lacking significant quantities of actual moon rock, they used a simulated moon dust known as “Regolith.” Dr. Bandyopadhyay seems almost giddy in the video, so it seems that the experiment went well.
One of the major obstacles to setting up a base on the moon or elsewhere in space is the enormous cost of bringing material and supplies from Earth. 3D printing seems like the ideal way to produce what is needed on location, thus saving the shipping cost, and NASA apparently agrees. Previously, we wrote about a proposal to 3D print structures on the moon, and this new experiment shows a continued interest in the technology.
Printing realistic 3D objects using standard paper.
Mcor’s IRIS printer, previously mentioned on this blog as part of Mcor’s deal with Staples, uses a deceptively simple method for its full-color prints. It “prints” objects by cutting out and gluing together hundreds of layers of paper.
One might imagine all sort of high-tech ways to add color, but Mcor chose a simple, yet highly effective approach. Hidden in a cabinet underneath the IRIS is a standard inkjet printer equipped with ink specially designed to soak through the paper, ensuring thorough color saturation (pictures below). The inkjet also prints a barcoad onto each sheet to make sure they are glued in the right order. (more…)
Print 14 materials simultaneously with a 1000 x 800 x 500mm build volume.
Objet’s newest offering, the Objet1000, is capable of printing with multiple materials on a large scale without sacrificing print quality. Large-scale 3D printing is slowly becoming more common, but large printers generally print at a low resolution. The Objet1000 is an inkjet-based printer capable of 600dpi on the x- and y-axis and 1600dpi on the z-axis with a 1000 x 800 x 500mm build volume. It can also print up to 14 materials in a single model, chosen from a materials library of 120 possibilities. (more…)
Fully functional Autobot transforms from Robot to Car in seconds
A walking, bipedal robot that can transform into a sleek street car may sound like the stuff of Hollywood fiction, but visitors to the Maker Faire in Tokyo next week will be in for a treat when they encounter the Brave Robotics Transforming Robot 7.2.
The latest incarnation from these masters of automation, this 1:12 scale robot can walk around in the familiar shuffling gait of its humanoid counterparts, while shooting missiles from weaponised forearms. In a matter of seconds the robot transforms into a fully functional vehicle that can be driven around just like a standard RC toy car. Further enhancements include a wifi camera that sends a live stream from the transforming robot to a nearby tablet.

Printing new hardware components is something 3D printers are commonly used for all across the globe. The way that these prints are being used is much the same as the commercial parts that they replace – as a plastic shell or block of material to surround the electronic innards of a device.
Imagine if you could use your 3D printer to produce a part with all of the electronics built in! Scientists at the University of Warwick have been making some exciting advances towards low-cost intergrated 3D printing with a material known as Carbomorph.
Working examples of this technology include game controllers with embedded sensors and touch-sensitive buttons, and a mug that can tell how full it is.
“In the long term, this technology could revolutionalise the way we produce the world around us, making products such as personal electronics a lot more individualised and unique and in the process reducing electronic waste.”
The Education sector is projected to be among the first to embrace Carbomorph, as this new conductive material will allow students to design high-tech devices and products that can be integrated with freely available open-source electronics and software.
Sugru sheds light on the unsung hero of creativity
Most of us have already encountered Sugru, and many are using it in all kinds of interesting, creative ways. The team behind this extraordinary putty have enjoyed becoming a hub for Fixers so much that they put their heads together to come up with an equally extraordinary document: The Fixer’s Manifesto.
“We made this to fuel the conversation about why a culture of fixing is so important.”
Drawing inspiration from documents such as the Repair Manifesto by Platform 21 amongst others, this variation seeks to expand and grow by tapping into the huge community of makers, thinkers and fixers that have already shown such inspired creativity using Sugru.
Click through to see the The Fixer’s Manifesto in full, and keep in mind that this currently exists as Version 1.0 in what is intended to be an ever-evolving credo that can be tweaked and tinkered with, in true Sugru style. (more…)
Using a moving print bed for large-scale printing.
Phantom Geometry, winner of the new Gehry Prize thesis award, is a project by students from the Southern California Institute of Architecture. It was developed in the Robot House, a facility where students have acess to advanced robotic arms, under the guidance of Peter Testa and Devyn Weiser.
The original article on FastCo appears to suggest that the innovation in the project was to use a projector and UV cured resin to produce 3D prints. I hope that’s not what the prize was for, considering that this has been done severaltimes already.
That confusion aside, this is a fascinating project. With typical UV resin 3D printing, the only movement of the print bed is to slowly lower, letting the project light cure one layer of resin at a time. In this case, both the print bed of resin and the projector are attached to robotic arms. This allows the machine to print structures many times larger than the print bed itself. It’s difficult to describe, so please watch the video.
The low cost stereolithography 3D printer reached almost 30x its funding goal and broke the Kickstarter record.
The Kickstarter campaign for the Form 1 stereolithography 3D printer beat all expectations and then some. It ended with $2,945,885 in funding, almost 30x the goal of $100,000. It had $1M in funding in the first day, and before the end it broke the Kickstarter record formerly held be the Oculus Rift of $2.4M.
What make the Form 1 special is that it is the first laser-based 3D printer available at an affordable price. While most stereolithography printers cost tens or hundreds of thousands, the Form 1 was offered for as little as $2299 for the first 25. It is aimed at (and price for) the professional market, but this price is still shockingly low compared to equivalent printers currently on the market.
