Completely New Means of Generating Electricity

A new means of generating electricity, one that utilizes bacteria to harness the energy of evaporating water, has been created by researchers from the Wyss Institute of Biologically Inspired Engineering at Harvard University. The method could potentially be used to capture the energy released by ponds, harbors, and other bodies of water when the Sun … Read more

New Life for Nitinol

Nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages. Nitinol alloys exhibit two closely related and unique properties: shape memory and superelasticity (also called pseudoelasticity). Shape memory is the ability of nitinol to undergo deformation at one temperature, then … Read more

An Elegant 3d Printer Design

The math is a bit trickier. But, hey, at least there are no moving parts to wear out in isomorphism. Whether you’re printing human organs or wall sections for building construction, chances are you’ve spent some time thinking about a gantry system. All things considered, a Rostock based 3d printer inspires through a performance that … Read more

Re-inventing the Wheel

If you’ve never explored the Thingiverse, perhaps the best place to start is with the wheel. This is very highly customizable wheel in the way of an OpenSCAD file with 46 parameters that provides a limitless set of combinations and wheel designs. In addition to the spoke options you see here, ou can select tread designs, … Read more

3D Printing – The First Snort is Free

It’s been selling all of us overpriced ink and toner for decades now, while basically giving its printers away. It plans to do the same thing with 3D printers by making them compatible only with proprietary spools and filaments. HP recently told the press that it has already developed a special polymer that its 3D … Read more

Making the Case for Open Source

No one makes a better case for open source hardware and software than the manufacturer of a high-priced, high-end CNC mill like the Mori Seiki NV5000 A/40. Even if you own the machine outright, if you move it at all, a GPS and gyro sensor package in the machine will automatically shut it down and … Read more

Open-Source, Software-Defined Radio Platform

Nuand has employed Lime Microsystems’ programmable RF silicon for its bladeRF, which – the two companies say – takes open-source RF hardware into the mainstream Lime’s field programmable RF chip, the LMS6002D, has been adopted for Nuand’s bladeRF, a Kickstarter-funded open source software defined radio. Following Myriad RF and Fairwaves, this is the third open … Read more

3D-printed Aston Martin

Aston Martin only made about 1,200 DB4 cars back in the day, and today some versions can fetch millions at auction. Ivan Sentch of New Zealand has printed about three-quarters of the mold parts for his handmade Aston Martin DB4. The resident of Auckland, New Zealand, has printed nearly three-quarters of the sections for his … Read more

A 3D Printer in Every Home?

Before 3D printers become as ubiquitous as cellphones, they could form the basis of small-scale manufacturing concerns and have huge potential both here and for developing countries, where access to many products is limited. Associate Professor Joshua Pearce, a Michigan Technological University researcher posits the following: “Say you are in the camping supply business and … Read more
