If you want to see if you truly understand how a mechanical system works, try making it out of cardboard. Artist Niklas Roy led the construction of a series of cardboard computers, including this plotter, as part of an electronic media class at the School of Art and Design, Offenbach. Watch the video above to see the remarkable sophistication of this mechanical computer. (more…)
Arduino, 3D printing, and clever engineering result in an affordable prosthesis.
Easton LaChappelle has made a series of continuously improving robotic hands. The first, which he made at age 14, won 3rd place at the Colorado state science fair, and the second, which we previously covered, won 2nd place at the Intel International Science and Engineering Fair, the top science fair in the USA. At the Colorado fair he met a little girl who wore an $80,000 prosthetic arm, and he was convinced he could do better. (more…)
“Soft robotics” like this have several potential advantages over the more traditional “hard” systems. A soft arm is more gentle with far fewer moving parts, and is, in some ways, more resistant to damage that a typical robotic arm. (more…)
Put one of those old cellphones lying around to good use.
Most people have at least one or two old cellphones sitting in a drawer somewhere. Now you can use one for your next Arduino project. Alex of insideGadgets has kindly posted a detailed tutorial showing how to hack and old Nokia 6110 (or any derivative) to send text messages from an Arduino. Even if you don’t have one of these sitting around, old technology (aka project materials) can be bought at absurdly low prices.
Filament making machine winds its way toward finishing its Kickstarter campaign rewards
We last looked at Filabot, the plastic extrusion filament maker for Makerbot and RepRap style 3D printers when Tyler McNaney was in the middle of his Kickstarter Campaign, that ended up successfully raising $32,330 and was more than 320% funded.
The Filabot is a desktop machine that aims to help reduce the cost of 3D printing for filament based and reduce plastic waste by turning it into “ink” or filament for 3D printers that print by depositing and fusing plastic together.
The Filabot Reclaimer has recently had a lot of development work from McNaney, whose working hard to fulfil his Kickstarter rewards orders by the end of the year. He, recently revealed the design for the production Filabot Reclaimer on his website. The case is made from folded CNC plasma cut steel. (more…)
An open source, 3D printable humanoid robot is in development and available for download from Thingiverse. Right now only the arms can be downloaded, but the head and torso are promised as soon as the design has been refined.
InMoov is a project by Gael Langevin, a French sculptor (Thingiverse user hairygael). Langevin has been working on InMoov since early 2012 and has gone through numerous design iterations and discarded 3D prints since that time. The progress is nothing short of outstanding. As you can see in the video below, this is a fully articulated humanoid robot, a rarity outside the research labs of corporations and universities. (more…)
MakerBot CEO Bre Pettis announced the Replicator 2X 3D printer at the CES technology event. The new printer is equipped with a heated build platform, dual extruders for multiple colors, the ability to print both PLA and ABS, and a 100 micron layer print resolution. It also has a fully enclosed build area with clear plastic windows (that oddly don’t appear to be shown in the above image).
This is arguably their most advanced 3D printer yet. It’s also their most expensive at $2799, clearly reinforcing the transition of MakerBot as a company from inexpensive hobbyist 3D printers to more professional-level machines.
New grassroots hardware from the Pacific Northwest.
The BrainWave board by Metrix Create:Space and Matthew Wilson is an all-in-one controller specifically designed for DIY 3D printers. It includes support for 4 stepper motors, a heated extruder, and a heated print bed. It’s also open source. And did I mention it was fabricated, assembled, and tested in the Pacific Northwest? The components are from overseas, but that’s nearly impossible to avoid these days.
Unfortunately, it’s not widely available quite yet; it is currently being beta tested to work out the bugs. Once launched, the BrainWave will sell for the very reasonable price of $100. (more…)
Web series uses puppets to inspire the next generation of inventors
Adafruit continues in their quest to make DIY electronics easy for all ages with Circuit Playground, a children’s web series that teaches electronics in a quirky and fun way.
“We’ll have each component have a story, a song and something to do”
From Cappy the Capacitor to Hans the 555 Timer Chip, this light-hearted approach will enable enquiring youngsters to immerse themselves in technology as they gain valuable real-world knowledge.
Supporting the show there are additional fun low-tech teaching aids including a colouring book and a set of plush dolls that will bring the characters to life. Combine this with the Circuit Playground iOS app and you’ve got plenty to not only keep the kids entertained and engaged with the learning process, but also maintain the underlying goal of inspiring the next generation of engineers.
“We want to celebrate the fun and good parts of making things, and even tackle complex subjects like what’s ‘good’ to make”
Circuit Playground is scheduled to air in March on Google+ and Ustream.
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.
