Center pivot pen plotter

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.”

3D printed exoskeletal support

Exo-Skeletons no longer mere sci-fiMagicArms 3D printed exoskeleton

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.

TED: Massimo Banzi talks Arduino

How Arduino is Open Source Imagination

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.

Open source filament maker

Plans now available for the Filabot WeeFilabot prototype

You might remember Tyler McNaney’s Filabot, the personal filament maker, we featured earlier in the year that about his Kickstarter campaign to raise money for development costs. The machine is designed to recycle plastic waste into filaments for use in 3d printing. (more…)

Harness the Bullduino

Red Bull calls out to makers

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.

Arduino controlled automatic pot stirrer

Ben Heck lets loose in the kitchen

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.

3D printed battleshots game

New meaning to the term “you sunk my battleship!

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…)

Robot makes its own custom tools

HMA printed parts on the fly

Robots are often designed with very specific tasks in mind. But what happens when you want a robot to be adaptable? Taking on the daunting task of coming up with a robot that can rise to whatever challenges it encounters, a team over at the Bio-Inspired Robotics Laboratory (ETH Zurich) have been making progress that could have serious implications in the world of digital manufacturing.

Utilizing Hot Melt Adhesive (the same HMA that we’ve all burnt our fingers with when using a handyman glue gun), their robot is able to create tools from scratch. It then makes use of these new devices to successfully complete tasks that it was otherwise unable to perform.

The following video gives an indication of where things are currently at. Although the process is similar to 3D printing, the team are quick to point out why they have chosen HMA rather than the usual thermoplastic materials. It all comes down to adaptability. A traditional 3D printed tool needs to be grasped/held/attached in some way. With HMA, the printed tool can be glued to the robot itself, and actually becomes a part of the machine. No need for graspers or fixing mechanisms. (more…)
