oobject: 'daily user-ranked gadget lists' have just released their updated list of the worlds most powerful supercomputers. In June all of the top 5 were in the US, now only 2 are, with India, Sweden and Germany appearing.Here's an interesting thing, you can make it into this list for less than the cost of a family house in Manhattan.The fact that a Swedish Military computer is at number 5 indicates that either the Swedish military require the world's most powerful computers, or they are just unusually unsecretive, and that there are many machines we don't know about.Here are the top 15, with pictures of the actual machines, where they have been built. Although the IBM Blue Gene has a simple and striking case, only the Barcelona Computer Center and Leibniz Rechenzentrum are contained in rooms that are at all impressive. Vote for which ones you think are worthy of note.

Named after the famous cartoonist, Rube Goldberg machines are unlike ordinary gadgets in that they are deliberately inefficient, taking the maximum number of steps to achieve a goal. Last years winner of the Rube Goldberg competition took over three hundred steps to squeeze a glass of orange juice.To truly appreciate RG machines you need to see them in action. Here is a list of videos of our favorites. Vote for yours.

The earliest wrist watches were made for soldiers, where fumbling around for a pocket watch was dangerous. The very earliest examples were from the Boer War, however the idea caught on in the first World War.Some of these watches were actually designed to be worn around the leg (for airmen), and many have the distinctive protective grille that gives them a medieval look.

Despite the appearance of permanence that historic buildings create, many if not most of the worlds famous cities have been almost entirely destroyed either by war, property speculation or Ayn Randian architects. They have been rebuilt, either as replicas (Warsaw) or even in the image of the culture that destroyed them (Hiroshima). Here are images where either we or others have matched up locations for incredible before and after shots.

The earliest remotes were neither wireless or used to control TVs. Since the 30s devices were available to control radios, Philcos 1939 wood and Bakelite model was actually wireless and predates any TV remote. TV remotes started with gadgets such as the Zenith Lazy Bones and it was Zenith who introduced the first cable free TV remote, with the Flash-matic.

Aside from their spectacular size, what makes floating cranes unusual and interesting objects is that they are essentially boats. As such, they dont exactly conjure up the idea of stability, which is the primary requirement for lifting things. They also look weird since boats usually consist of large hulls with smaller superstructure, here the arrangement is reversed making them seem very ungainly.Some of these cranes can lift tens of thousands of tons, at sea, and are engineering wonders.

The Zapruder film of the JFK assassination was shot on a Bell and Howell double 8 camera, at about the time of the introduction of Super 8, which created a ubiquitous format for affordable home movies. The difference in design between the Super 8 cameras and other 8mm cameras from as early as the 30s is clearly visible in this collection. The look changed from rounded shapes dictated by the film canister on early news reel devices, to a counter fashion for extremely orthogonal forms as exemplified here by the Star Trek like designs of the superb Bolex 150 from 1967.

Yesterday we managed to get into CERN and do some exploring. Our mission? Not to go to the Giant LHC experiments, such as Atlas, but to root around the campus itself, find the exact place where Tim Berners Lee invented the web, marked by a small plaque, and photograph it, license-free, since there seem to be no images of it that we could find. We went through several doors marked ‘radiation’, were told to leave one place, because ‘the beam was on’, saw the Grid data center and rooms with blackboards covered in equations – but we found it.

Here is a roundup of collectible boomboxes, currently being auctioned on ebay. The mannerist nature of 80s ghetto blasters could not be more different from today's minimalist trends in consumer audio gear, lead by Sony and Apple. Because of this, these devices now look obviously obsolete and different and are starting to become collectors items. Ugly, but interesting, and representative of their time, some are perfect examples of pointless feature driven design, something which still plagues software.

In some ways, an ordinary cellphone on vibrate, or a rumble pack are examples of haptic devices, however, the recent focus on the physics of interfaces means that haptics are soon going to be much more sophisticated. The reason for this list is actually to show how limited the scope of haptics is currently, despite the opportunity with systems that resemble the primitive virtual reality fad that coincided with the birth of the web. With a bit of imagination, however, some of the possible applications of haptics are shown.

There is something intensely creepy about submarines, not least because, as we found out from the two that had crashed into each other recently, they carry a thousand times the explosive power of the Hiroshima bomb in a claustrophobic metal sarcophagus powered by the same stuff as the bombs. Because of this, and because of their featureless exteriors which hide immense complexity they provide the same kind of kick that a complicated gadget in a smooth case provides. Just like gadgets its interesting to see how they work when they are being assembled or taken apart. Here are our favorite views from the science fiction like decommissioning of Soviet attack subs to rotting reactor cores to components being wheeled through English roads.

The invention of the digital watch made accurate timekeeping a cheap commodity. This meant that expensive watches were a quixotic anachronism in terms of pure design. However, this very fact meant that designers were free to innovate timepiece designs for fun. In addition, the development of watch sized miniature electronic gadgetry meant that the wrist watch form factor could be used for other gadgets. For things like phones and MP3 players this has proved to be a failure, however included here are some interesting concepts for other uses for wrist devices such as insulin dosage, braille watches and health monitoring

Bladerunner - so where are we now? Particularly where are all the artsy animated building facades?Here are 15 of our favorites, avoiding Vegas style tacky glitz. We have tried to include some of the more recent architectural projects where the media skin is part of the design itself, rather than merely a billboard. Media skins are often designed by specialist firms in concert with the main architect, such as Berlin's, excellent, Realities United, who worked on several of these projects.

One of the negative things about technological progress is when something that was originally intricate and mechanical becomes a ubiquitous piece of cheap technology. This happened in the 70s with watches and more recently has happened with cameras.A modern day spy camera is not that interesting, but the miniature ones here are, similarly the wide range of hardware solutions create much more design diversity in early cameras, from the giant 900lb box camera to the bizarre miniature ones developed for carrier pigeons, from gun like trigger activated shutters to a propeller powered film advance mechanism for a camera mounted below an early aircraft.

Tourbillon watches are the most expensive in the world often costing $500,000. They became fashionable in the last decade as non-forgeable status symbols for billionaires, but that is now being threatened by Chinese imitations.The style of these devices is baroque in the truest sense, but becuase their aesthetic derives from the rational world of mechanics the style jars and they are, to my mind, as grotesque and kitsch as their diamond encrusted counterparts in the luxury watch market.After facing the existential threat of digital which made accuracy cheap, the Swiss watch industry turned to making high end jewelry either directly with diamond encrusted gold watches or indirectly via those that fetishised complex mechanics for the sake of it, such as these. Ironic, since the origins of Swiss watch making came from the ban on jewelry in Calvanist Geneva.These tourbillon (whirlwind) watches are the most extreme example of complex analog mechanics, the most expensive clockwork items in the world, costing between $100,000 and $500,000, they all share a rotating escapement which theoretically leads to better accuracy (even though that does not compare to a $50 swatch).This mechanism is very difficult to make and fascinating to look at, so most tourbillon watches directly expose their intricate mechanics, which originally only the Swiss could make. Recently, however, Chinese watch makers have brought tourbillon watches to market, for a tenth of the price, threatening their cache as a status symbol which is difficult to fake.

Anyone self respecting geek who has been spellbound by the inspired rescue of the Chilean miners, will have found plenty of great info-graphics showing just how impressive a mine is. Here we have gathered some other cutaways, sections and 3d models showing a variety of mines, from the two coal mine alternatives (room and pillar or longwall) to the cavernous chambers of salt mines. Most impressive of all, however, is the physical model of Kidd Creek mine in Ontario where the relatively insignificant looking blobs at the bottom are the world's tallest man made structures, to scale.

Just when people are talking about banning the incandescent light bulb, designers are noticing how beautiful they are and making lamps which show of rather than hide bulbs. Here is an eclectic list of items in honor of the humble light bulb, including a couple of takes on other types of lamp, for good measure

A perfect environmental nightmare, these hellish looking open faced mining machines have been largely decommissioned. Luckily some are being preserved as they are staggeringly impressive. The Ferropolis in Germany has many of these machines on display and forms an industrial park which host the famous MELT music festival. There have been several images of these floating around blogs, including the infamous pictures of the bucket wheel excavator that swallowed a full sized bulldozer, however we have tried to find as large a variety as possible.

Mechanical horse are interesting because they straddle the gap between the era of the internal combustion engine (we still notionally benchmark our cars relative to horses through horse power) and that of bone & gristle.

What passes for interactive clothing often consists of a button to control your iPod from your sleeve.Here is a roundup of some more interesting interactive clothing ideas, including a jacket whose fur stands on end like a scared cat, a bikini whose breast pads inflate as a life saver and a jacket with a digital organism that grows as you wear it. These are alongside some more serious ideas such as a medical monitoring clothing and a robotic jacket to aid the paralyzed. Some are fairly well known, but others are hopefully new to you.

Diving bells were originally just that - an upturned church bell with enough trapped air to stand in while reclaiming things from shipwrecks in relatively shallow water. As such the engraving of Edmund Halley's 18th century diving bell is one of my favorite images on oobject, because it shows gadgetry from an age prior to machines. There's a guy walking around the sea floor in what looks more like a velvet courtier's outfit that a divers suit. This list is a collection of images of diving bells that evoke that same sort of weirdness, as best I could find

Although we previously did a list on diving helmets, the variety of strange diving outfits warranted another list. Having spent hours pouring through these to pick my favorites, it occurred to me that the inspiration for early science fiction robots and space suits, before the age of actual space travel, clearly comes from this pre-space age technology.Deep sea diving equipment needs to be solid and heavy it has a very different aesthetic from aviation and space equipment which needs to be light, so there is a market difference between the look of space things in science fiction, between the 50s and 60s.

A three year challenge to recreate the equipment used by Mallory and Irvine in their ill fated attempt to climb Everest in the 1920s revealed that they were adequately clothed, wearing an unbelievable number of layers, as shown in this list. Today, the number of layers has changed as have nearly all the materials used for Everest kit, with high tech, breathable yet waterproof fabrics and lightweight alloys. The extreme requirements of Everest are a good way to demonstrate technology and design innovation through history.
