Heart rate monitors connected to an ink plotted graph are a staple of movies and TV and they usually come in beautiful portable versions by companies such as Lafayette Systems, making them a classic spy suitcase gadget.Polygraph lie detectors are widely believed to be useless quackery, no more effective than a Scientology Dianetics machine, but they are commonly used by law enforcement and government agencies, usually in the US and are an anachronistic cultural legacy of the cold war.Today, the classic analog polygraph is being replaced by much less interesting computer versions.

Balloons formed the origins of what became the USAF, have been used for stratospheric parachute jumps, bungee jumps and even to test nuclear bombs. Vote for your faves.

Some of the amazing projects recently built or currently under construction in China's rival cities. We have tried to pick links to the latest state of construction where possible. What is emerging is a distinct stylistic difference, Shanghai is about glitz while Beijing scores on architectural innovation, although this largely due to the Olympics and the role of Beijing as the capital.While the Arabian peninsula has overtaken the US in raw architectural point scoring (not one New York skyscraper will make the top ten tallest there within a couple of years), China is producing buildings on both a scale and quality that now far exceeds the US.

Ironically, airports are one of the few things you often don't get to see an aerial view of since you don't get a cockpit seat. Here are a dozen of our favorites, purely in terms of their abstract graphical layout. See if you can guess them.

Giant centrifuges are used to test whether fighter pilots or astronauts can deal with extreme G forces, pilots having 3 chances to survive a 15 second 6G test to be able to qualify. Here are some videos of the results of the effects of these tests up to 10G and on a range of suspects from pilots to Iron Maiden's lead singer.

Metal plate armor is one of the few technologies that emerged, disappeared in the 18th Century then re-emerged briefly during World War 1. Because of the this, WW1 armor has a particularly creepy, anachronistic look, from chain mail fringed splatter masks to body armor which looks decidedly Roman.

The Enigma is one of the most well known devices in the history of gadgets, being responsible for the birth of the computing industry, in attempts to crack it. This has largely overshadowed the plethora of other cryptographic devices, which are often overlooked. Here is a gallery of 20 secret message machines.

Really complicated, and really expensive swiss watches are called grand complications based upon strict criteria.These are often based upon the gravity compensating tourbillon mechanism that isn't strictly needed for a wristwatch but is insanely complicated so people build them to show off their skills as watchmakers.This is the kind of gadget that gazillionaires with enough taste to avoid diamond encrusted ones buy when they fly into Geneva. They look very James Bond - except that they cost ten times as much as his humble Rolex or Omega, often costing more than $100,000 each.

Thanks to an intrepid group of urban explorers, some of the most magnificent hidden engineering triumphs that lie, hidden, beneath the streets of the worlds cities are being recorded and posted on underground (no pun intended) websites.Here are some of our favorite sewers and drains, from Paris tourist attraction sewers to Londons Escher-like, arched, Victorian Gothic drains, to still working ancient Roman systems and the infamous giant storm drains beneath Tokyo. Vote for your faves.

The fact that if a nuke is used to extinguish the Deepwater Horizon leak, it will be the 6th time this has been done speaks volumes of how extreme the technological requirements of our fossil fuel dependence.Oil and gas require a gargantuan infrastructure of superlative technology that permeates every level from extraction to dispatch, from hellish looking oil drill bits, drilling rigs that are the size of cities, storage tanks the size of cathedrals and pipelines that rival the Great Wall of China.The extreme environments that this technology operates in require unsinkable boats, skyscraper sized structures in some of the world’s least inhabited places and firefighting tools that include large bombs and fighter jet engines.Pause for a moment and reflect on just how unusual these objects are.

Zoetropes, Phenakistoscopes and Praxinoscopes were the machines that formed the basis of modern day movie making. Here are some movies of these amazing machines in action, complete with some great modern interpretations.

What the list says - a collection of pod shaped enclosures from a health monitoring system, to a tree house, escape module, house, bed and office.

As flat screen TVs become ubiquitous, vintage TVs look more and more interesting and unusual. From early mechanical TVs consisting of a spinning disk and lens (which look even better without an enclosure), to Sony's original transistor TV and portable LCD sets from as early as the 80s. Here are some of our favorites from collector sites around the web.

Pininfarina made their name as stylists of classic Ferraris. They continued their distinctive design tradition through other exotic sports car brands to ordinary sedans and, since the 80's, household product deign. Some of the latter products are hit-or-miss, but at their best there is no other company quite like them.Andrea Pininfarina, the grandson of Battista ‘Pinin' Farina, the auto design company's founder, and the current CEO was killed today. Trajically and ironically he was hit by a car while driving a Vespa scooter.

When the shuttle takes off tomorrow it will be a symbolic example of technological regress, a small step down for man, a giant plunge for mankind. After the Shuttle, there will longer be re-usable space vehicles, no rocket capable of taking us to the moon, no submersible capable of taking us to the bottom of the deepest ocean. Airline travelers will only be able to fly half as fast as they used to and most seriously, children will get diseases that were previously wiped out all because progress doesn’t always happen and because some people don’t believe in it.I’ve picked 9 examples of technological regression, they will be ordered according to your votes – pick the the ones you think are the biggest loss.

The most claustrophobic places in the world. Imagine sleeping in a space smaller that a jail cell, deep under water, with a very large live bomb. This is what the business ends of submarines look like. Brass or steel hatches, like the eyes of a metal insect, peer out on a tiny Jules Verne-like space covered in buttons, gauges and levers, which often contains bunks right next to the torpedos themselves. Torpedo rooms are one of the strangest man made spaces on earth, or rather below it.

Here are some examples of things we put in space that came back down. They went up shiny and futuristic and what came back looks like medieval remains.

Today, prosthetics are a world apart from these pre-digital age examples, using advanced robotic and cybernetic technologies and tools such as 3-d printers for mass customization. As such vintage prosthetics often have the particularly strange look which is both creepy and fascinating and accompanies technological obsolescence.Early prosthetic limbs date from ancient Egypt and Rome, however examples from the middle ages appear more regularly, being made of armor. The were later replaced by non articulated wooden prosthetics, of the caricature style normally worn by pirates. The tragically large number of amputees in the Napoleonic Wars led to the development of the 'Clapper', named after the sound made by its articulated toes which were controlled by artificial tendons. This prosthetic became the model for the 'American Leg' which was developed during the American Civil war. Wooden prosthetics were heavy and were not improved on till the development of lightweight alloys, during the first World War.

The picture of people hunched over radar screens is the ultimate image of the cold war. Here are a collection of various radar consoles, from land air and sea and from round analog displays with orange, green or blood red displays, to today's computer monitor versions.

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.

The fact that vinyl is somewhat obsolete is exactly what drives the quixotic ambitions of high end turntable manufacturers to produce ever more extreme engineering solutions to sliding a diamond through a wavy notch and amplifying the wobble.The common ground here is to make a very heavy and rock solid platter and to move the motor as far away from it as possible, to avoid interference. The prices of these things range from under $1000 to a staggering $150,000

Some of these are very high end audiophile speakers and others are those that we think are well designed from a product point of view. Extremely well designed or extremely well engineered.The Kef Muon's are an unbelievable $140,000 while others are as low as $100. Our favorites are the 1960s Quad Electrostatics which are unlike anything ever made since and go nicely with a classic Quad 33 and 303 Pre and Power Amp.Its somewhat unfair to vote on something that is to be listened to and not looked at, so vote with your gut.
