Baolab Microsystems has developed innovative, pure CMOS MEMS devices that use Lorentz force sensors to detect the strength and direction of the Earth’s magnetic field. The new 3D Digital NanoCompass™ technology matches existing performance benchmarks for sensitivity, power consumption and package size at dramatically lower cost. An additional unique feature is autocalibration for consistent accuracy.
The new compass chips utilise Baolab’s NanoEMS™ technology, which allows nanoscale MEMS devices to be fabricated using standard high-volume CMOS lines and fully integrated monolithically with analogue and digital electronics. The MEMS elements are defined within the existing metal interconnect layers on the wafer as part of the normal CMOS production process. Conventional 3D compass devices typically use magnetoresistive materials or Hall-effect devices combined with magnetic field concentrators to detect the direction of the Earth’s magnetic field. [via]

RS Components has released PCB Converter for SketchUp, a software tool that converts CAD files in Intermediate Data Format (IDF) to Collada format for use in SketchUp. This enables designers to use SketchUp as a 3D CAD back-end for to PCB design and brings SketchUp into the electronic product design realm. [via]

Earlier today Intel announced that its 22nm process would not use conventional planar transistors but rather be the first time Intel is using 3D Tri-Gate transistors. This is a huge announcement that fuels Intel’s leadership in the mobile/desktop/server CPU space and makes it a lot more attractive in the SoC space, let’s understand why.

Drone writes: Now you can 3D print in glazed ceramics at Shapeways. Great! I need some big HV insulators for the electric chair I’m building. Interestingly, prices are based on surface area. [via]
Glazed Ceramics is perfect for any application such as a plate, cup or bowl as it is the first 3D printed food safe material available on Shapeways. Shapeways 3D Printed Glazed Ceramics material properties are exactly the same as standard ceramics as it is produced with fine ceramic powder which is bound together with binder, fired, glazed with lead-free, non-toxic gloss finish.

Printers capable of producing three-dimensional objects have been available for years. However, at the Vienna University of Technology, a printing device has now been developed that’s smaller, lighter and cheaper than ordinary 3D printers. With this kind of printer, everyone could produce small, tailor-made 3D objects at home, using building plans from the Internet – and this could save money for expensive custom-built spare parts.

The basic principle of the 3D-printer is quite simple: The desired object is printed in a small tub filled with synthetic resin. The resin has a very special property: It hardens precisely where it is illuminated with intense beams of light. Layer for layer, the synthetic resin is irradiated at exactly the right spots. When one layer hardens, the next layer can be attached to it, until the object is completed. This method is called “additive manufacturing technology”. “This way, we can even produce complicated geometrical objects with an intricate inner structure, which could never be made using casting techniques”, Klaus Stadlmann explains. He developed the prototype together with Markus Hatzenbichler.
This method is not designed for large-scale production of bulk articles – for that, there are cheaper alternatives. The great advantage of additive manufacturing is the fact that is offers the possibility to produce taylor-made, individually adjusted items. The prototype of the printer is no bigger than a carton of milk, it weighs 1.5 kilograms, and at just 1200 Euros, it was remarkably cheap. “We will continue to reduce the size of the printer, and the price will definitely decrease too, if it is produced in large quantities”, Klaus Stadlmann believes.

If you’d like to try your hand at turning on a lathe, but don’t want to shell out for a machine, how about printing your own EZLathe? Paul writes: [via]
So I’ve built a complete mini lathe system I’m calling the EZLathe… Fully 3D Printable except a small motor, and a couple pieces of cheap electronics. And able to do small wood turning jobs, or small pieces of pretty much anything.

We recently ran across another 3D printable PCB accessory on Thingiverse. This time it is a stand-off that slips on the edge of a PCB and the edge of a piece of plywood. This is a quick way to mount your PCB on the side of a project or into a project enclosure.
