Ricoh GXR - the world's smallest and lightest interchangeable lens digital camera

After weeks of speculation and the accidental pre-announcement release of a demonstration video, the Ricoh GXR digital camera system has finally been officially announced. Not only is it claimed to be the smallest and lightest digital camera that allows lenses to be changed, but as the lens and sensor comprise one interchangeable unit, photographers can now choose different sensor/lens combinations for different photographic conditions.

Spiraling maple tree seeds inspire world's smallest single-winged rotocraft

Students at the University of Maryland’s Clark School of Engineering have turned to nature to create a flying device that can hover and perform surveillance duties, and that could lead to applications for military and emergency services. The enigmatic maple tree seeds (or samara fruit) - and the unique spiraling pattern with which they glide to the ground - have intrigued children and engineers for decades. Now aerospace engineering graduate students have applied the seeds’ design to airborne devices and created what they believe to be the world's smallest controllable single-winged rotocraft. Read More

CATSi - the world's smallest GPS, GSM and RF tracking device

The CATSi, (pronounced cat's eye), is designed to track almost anything, from pets and people through to cars, trucks and motorbikes. Although we’ve seen plently of GPS trackers before, CATS-i is touting the its new product as the world’s smallest, thinnest and most covert GPS, GSM and RF tracking device ever. This means the device can be used in products that have previously been inaccessible to GPS tracking - little Jimmy should have a hard time detecting a CATSi sewn into his jacket for example.

The world’s largest ambulance (and the world’s smallest X-ray unit)

"Scalpel please! " is a sentence that might in future not only be heard in a hospital operating theatre, but also in one of the three new, large-capacity Mercedes-Benz ambulances handed over to the Centre of Ambulance Services of the Government of Dubai. From now on, it is the hospital that comes to the patient in Dubai. The clinic buses were ordered so that rapid medical assistance can be rendered in the event of major emergencies with large numbers of injury victims. As is well-known, the survival chances of very seriously injured persons in large measure depend on rapid first treatment, and this is the purpose of the large-capacity ambulances. Read More

World's smallest working fuel cell

People are becoming more and more reliant on the portable gadgets they carry every day and at no time is that reliance more pronounced as when those gadgets’ batteries run out of juice. While we’ve seen some fuel cell technologies appear in recent years that offer the future prospect of powering portable devices, none are quite as small as this new working fuel cell created by US chemical engineers and featured recently in New Scientist that measures just 3 millimeters across.

World's smallest video projector

The EPP-HH01 Pico Cube from Epoq Multimedia lays claim to the mantle of the world's most compact and lightest portable video projector. We're not sure how accurate the claim is, but a unit which includes a speaker in its 2 x 2.2 x 1.6 inch footprint is pretty impressive, and anyway, it's a title that will undoubtedly change hands many times in coming years as video projection systems shrink rapidly to satisfy our mobile multimedia demands.

World's smallest camera carrying Micro Aerial Vehicle takes flight

July 28, 2008 How often have you thought, “I’d like to be a fly on the wall in that room”. Well, a team at the Delft University of Technology in the Netherlands is hard at work trying to make that desire a reality by developing a Micro Air Vehicle (MAV), which they claim is the smallest flying, camera carrying ornithopter in the world. The DelFly Micro weighs just 3 grams and measures 10 cm from wing tip to wing tip. It has a range of 50 meters and is powered by a 30 mAh lithium polymer battery, which provides enough power for three minutes of fight time. To keep the weight of the unit down the wings are made from Mylar foil, while the body and frame is made up from carbon and balsawood. Read More
