Spanish engineer crafts "world's smallest" V-12 engine

Anyone who appreciates the precision art of engine design ought to get a kick out of this offering from a Spanish engineer named Patelo. Starting with hunks of aluminum, bronze and stainless steel, he spent over 1200 hours designing, milling, turning and drilling what he claims is "probably" the world's smallest V12 engine. Powered by compressed air injection (0.1kg/sq cm), this little marvel boasts a total displacement of 12 cubic centimeters from its twelve 11.3 mm diameter pistons and works like a charm. Best of all, you can see it come together in the detailed video that follows. Read More

It's the world's smallest electric car - by a BIG margin

We’ve seen some fairly small electric cars in recent years, such as those made by Tango, Think, Wheego, and of course, smart. All of those automobiles are absolute monsters, however, compared to what scientists from Swiss research group Empa have created. Working with colleagues at the Netherlands’ University of Groningen, they’ve built a one-of-a-kind electric car that measures approximately 4 x 2 nanometers. Read More

'World's smallest electric motor' consists of a single molecule

Remember back in the old days, when nano-scale motors were a clunky 500 nanometers across? That record was subsequently broken with a 200-nanometer model, but has now been broken again, by a motor that’s just one nanometer wide. By comparison, the width of a human hair is about 60,000 nanometers. The new motor, created by scientists at Tufts University in Massachusetts, is reportedly the first one ever to consist of a single molecule. Read More

Pentax claims world’s smallest and lightest interchangeable lens camera crown

Pentax has announced the first pocket-friendly interchangeable lens camera to sport its new bayonet lens mount. The company says that its Q mount is about a third less in diameter than the more familiar K-mount, thanks to a reduction in the distance from the lens mount surface to the image sensor and by tweaking the size of the lens image circle to be proportionate to the sensor. The Pentax Q also makes use of a compact camera-sized sensor and sacrifices the onboard optical viewfinder, mirror box, focusing plate and autofocus sensor to help keep proportions to a minimum - making it about the same size as my Umbra credit card case. Other features of note include a programmable dial on the front for quick access to frequently-used settings, the ability to shoot full high definition video and a built-in flash that can pop up to help reduce red-eye.

Medical tech company creates world's smallest video camera

Medigus has developed the world's smallest video camera at just 0.039-inches (0.99 mm) in diameter. The Israeli company's second-gen model (a 0.047-inch diameter camera was unveiled in 2009) has a dedicated 0.66x0.66 mm CMOS sensor that captures images at 45K resolution and no, it's not destined for use in tiny mobile phones or covert surveillance devices, instead the camera is designed for medical endoscopic procedures in hard to reach regions of the human anatomy.

Foremay announces solid state drive smaller than a quarter coin

Californian SSD manufacturer Foremay has announced a new addition to its OC177 storage family. Despite being smaller than a U.S. quarter coin, the company's first disk-on-chip (DOC) solution will be available in capacities up to 64GB, supporting both standard IDE or SATA host interface, in addition to complying with ATA-7 specifications. The new DOC drive is mounted directly onto a motherboard which, the company says, negates the need for a separate storage drive while offering devices some rugged credentials. Read More

Poco PRO - the credit card-sized 14-megapixel compact digital camera

With cameras pretty much standard equipment on mobile phones nowadays, a lot of people don’t bother with the extra hassle of carrying around a separate one, even if it means sacrificing picture quality for convenience. While we can’t comment on the picture quality, the Poco PRO from Iain Sinclair certainly seems to tick the right boxes in the specs department and won’t be too much trouble to cart around thanks to its credit card-like dimensions.

World’s smallest battery created

Because battery technology hasn’t developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running. Now a team of researchers working at the Center for Integrated Nanotechnologies (CINT) is claiming to have created the world’s smallest battery, and although the tiny battery won’t be powering next year’s mobile phones, it has already provided insights into how batteries work and should enable the development of smaller and more efficient batteries in the future.
