Heptagon Micro Optics Pte. Ltd. (Singapore) has announced that their 2 by 2 3D imaging system for use in smartphones, phablet and tablet computers is now ready for mass production. The TrueD H2 array camera is said to be the first in a series of 3D imaging and depth-sensing cameras that Heptagon will be introducing to the market.
Heptagon’s manufacturing processes enable the system aperture; stray light control and infrared cut filter to be integrated onto a single glass wafer. The assembly can withstand reflow temperatures and its no-focus lens eliminates the need to refocus after assembly. As well as grabbing the image the array camera captures short-range depth information that can be used for gesture and user recognition and allows background removal and image enhancement. Although this feature would typically be useful on a smart device’s front-facing camera, Heptagon state that it could also be used to complement the smart device’s primary high resolution image sensor. Applications include supporting 3D and immersive mobile video games as well as augmented reality overlays. [via]

Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart, and potentially allow more of patients’ clogged arteries to be cleared without major surgery.
The device integrates ultrasound transducers with processing electronics on a single 1.4 millimeter silicon chip. On-chip processing of signals allows data from more than a hundred elements on the device to be transmitted using just 13 tiny cables, permitting it to easily travel through circuitous blood vessels. The forward-looking images produced by the device would provide significantly more information than existing cross-sectional ultrasound.

A new, free 3D design tool aims to help engineers with 3D modeling of their designs by being easy to use. RS Components and SpaceClaim joined forces to develop the tool, which can be used to model physical elements of designs, such as enclosures or interface panels, without having to learn complex feature-based 3D tools. It can also be used to develop early prototypes, either as a PDF file or on a 3D printer.
DesignSpark Mechanical aims to overcome the two major entry barriers faced by potential users: the cost and steep learning curve of traditional 3D CAD tools. DesignSpark Mechanical is free, and it uses direct modeling so that engineers and others involved in product development can learn to use the software within minutes. [via]

OMG! All the electronic and mechanical engineers I know (and even most of the marketing folks) are going to squeal like schoolgirls when they get their sticky little hands on this amazing, free 3D design software that will enable conceptualization and rapid prototyping, reduce costs, and dramatically accelerate product development. In short, this software is like a “Gift of invention that will bring your ideas to life!”
Quiet down my racing heart! I just heard the most amazing “hot-off-the-press” news. In just a few days as I pen these words, all of us who wish to will be able to design 3D models, assemblies, and enclosures for our designs using some incredibly intuitive, fully-featured 3D modeling software. And, best of all, it’s free! (And when I say “free” I really mean free, as in free for both commercial and non-commercial use with no limitations or licensing.)

Jérôme Vuarand developed an application to visualize Gerber data, a simple 3D viewer for Gerber files. This tool helps to review Gerber files before sending them to a PCB fab house:
Over the course of the last 5 months I developped an application to visualize Gerber data. The goal was primarily to review Gerber files before sending them to a PCB fabrication house. It is very similar to the Mayhew Labs online Gerber viewer, except it’s offline (and has a few different features).My tool is program for Windows (32bits or 64bits) that use OpenGL for visualization (you will need a decent/recent video card). You can simply drag and drop Gerber files on it, or use the command line to configure it more deeply. I set up a page explaining most of that and giving download links

UV resin based mUVe 3D Printer releases source files:
The mUVe 1 3D Printer, an open UV resin based 3D printer was successfully funded on indiegogo back in April. As estimated, the first Ultimate kit was shipped out on Jun.20. Last weekend the team has completed building and shipping all of the Ultimate kits. Meanwhile Dean Piper, the maker behind the mUVe 1 3D Printer project, has shared all of the source material on their website

3D printing a battery itself is a remarkable achievement. A 3D printing a battery as small as a grain of sand is a giant hurdle forward in both, 3D printing and battery technologies. That is exactly what researchers working at University of Illinois and Harvard have done. To achieve this process the researchers had to create their own custom 3D printing technology. Although there are many types of materials 3D printers can use, most print objects using small liquid droplets, which build upon one another to create the object from the bottom up. For the researchers this process was not sufficient to achieve their goals. Therefore, they designed a 0.03mm nozzle, which releases the liquid materials continuously in a fashion, which is similar to toothpaste being squeezed from its tube. In addition, the researchers also invented a 3D printing material that is electrochemically active, which ultimately allowed the printed battery to store and release charges.

Infineon Technologies has released a family of 3D image sensor chips for touchless gesture recognition. Developed in cooperation with pmdtechnologies, the new chips are the first to combine a 3D image sensing pixel array with the digital conversion and control functions needed to develop very compact and accurate systems for gesture recognition applications in computers and consumer electronics devices.

Christopher Hawkins made this cool DIY 3d printed stepper motor: [via]
This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed around these things. My goal was to make something about the size of a business card that moved. You can’t exactly fit it in your wallet but it does indeed move. It just a first draft- there’s lots of room for improvement. It has a step angle of 15 degrees (although the way I’m driving it, it is 7.5 degrees.)

Christian Aurich developed a script to import Eagle boards into FreeCAD. This way he is able to design custom enclosures.
The common solution until now is to export your board with eagleUp and assemble it with a case in Sketchup. This also gives you some drawbacks. The most important to me was that the Sketchup files are mesh based like the data used for 3D printing usually, but for further use in CAD systems this is not really usable. You also will not be able to get a STEP model that you can give to your costumers out of this data.
