Human Detector

I'm trying to come up with a small, cheap, simple circuit that will detect a human. I plan to use a grid of luxeon rebel OLEDs and whatever detector I come up with embedded in my ceiling to light up only when you are under them. I've looked into passive infrared, but it's fairly expensive for the components I could find. Any leads for circuits, ideas, or parts? I'd use parts from cheap security lights, but they tend to be around $10 each and I would probably need around12-18 ... kinda painful on the pocketbook. Thanks in advance for any help!

The Human Machine

It isn't that long ago that explaining human physics and behavior was imagined by copper etching. This picture seems funny to us now. But 100 years ago this was the way to explain the functions in the human head. I found this picture in an old book and I want to share it with you. This is nice for silkscreening or transfer print at T-shirt or any other surface. When you want High-Res 2208 × 2732 and 300 dpi let me know.

Smile, humanity!

On the 19th July, the Cassini space probe is being turned around to take a photo of Saturn and its rings. When they take the photo, Earth will be in the background, so this is your chance to get outside and photobomb an entire other planet! See here for details of exact timings, but most US, Canadian and Western European members have a chance to be in the shot. There's also a contest to get your image or music beamed to the stars.

Human Nature

To whom it may concern (mainly the ones who chose to blast my consern about the pop tab chainmail armor). Have You people forgotten the fact that as a species humans are incredably stupid??? I know My spelling is not dead on, Please forgive Me! I have to quote Tommy Lee Jones from M.I.B. 1. " A person is intellagent (?), People are dumb, paniky(?) animals. And You know it!" I could just see a newbie log on, find that information, build it and expect it to protcect them at the next S.C.A. event!! The Terry Pratchet comment was totaly funny and true!!(I am a true madman.) Thank You for noticing!!! I was only trying to help! Maybe others should also!!! Thank You!! Roy Smith.

Way Of Detecting Humans?

Is there ~~an easy way~~ a best way of detecting humans in the dark, or in a forest? Me and my friends play airsoft, usually in a forest, and it's hard to know where the enemy (other friends) are. I'm a sniper and I want an easy way to detect them. One way would be a thermo-camera, but those are expensive. Is there a better way?

Witnessing Human Flight

First posted here. Last Friday, I drove up to Maryland to see UMD's Gamera II human-powered quadrotor. They are currently pursuing the Sikorsky Prize, established in 1980. Here's the team testing a new control system. http://youtu.be/3B2of4V35d0 (sorry, the embed function isn't working)   During this test, Gamera II flew for approximately 65 seconds, unofficially tying the endurance record that the team previously set. This flight time, plus the ability to remain within a specific boundary, satisfies two requirements of the Sikorsky Prize. Because the rotors are so close to the ground, the helicopter is benefiting from a cushioning effect of the air between the rotor blades and the ground. This effect will diminish exponentially when the team attempts sustained flight at the required 3 meters. The helicopter transfers the pilot's pedal power by unspooling cable from pulleys, mounted on the shafts of each of the four rotors. Flight time is limited by the pilot's stamina and the amount of cable stored in each pulley. The rotors are constructed of carbon fiber, balsa, and foam, and are covered in a plastic film.  All in all, it was a cool experience. I've never seen so much carbon fiber in my life! I look forward to seeing the team win the Prize.

Is evolution over?

Geneticist Professor Steve Jones has said that human evolution may be over, and that we may now, as a species, be on the slippery slope to extinction.He's not saying evolution in general has stopped, just ours.His theory is that our development and exploitation of technology has de-coupled human development from natural selection. Conditions which would have meant an early grave for our ancestors, through starvation or other side-effects, are now barely considered as inconvenient, let alone life-threatening.Personally, suffering asthma and 8 dioptres of short-sight, I would have quickly starved to death in our hunter-gatherer days, unable to keep up with prey animals or to see well enough to tell "nutritious" from "poisonous".What this means is that we have a rate of survival to age 21 that is almost 100%, double what it was in ancient times.At the same time, our supporting technologies, particularly in medicine, mean that there is a growing accumulation of deleterious genetic conditions in the general gene pool.Increases in world travel have also meant that the differences between different human populations, already low, are getting smaller, as openness and acceptance of other cultures has started to homogenise our phenotype.The result - we are isolated from natural evolutionary pressures, so there is nothing to stimulate natural selection, nothing to weed out potentially-dangerous mutations. We are stagnating.So, what next?On the one hand, the pessimistic view is that, at some point, our genome will become so laden with hazardous mutations that we will cease to be viable as a species. We will be unable to reproduce successfully.On the other hand, maybe other species, still closely linked with natural selection, will continue to evolve until they supplant us. The obvious choices are chimps and gorillas - if we don't drive them to extinction.Or maybe our heirs are currently underwater - dolphins, maybe? Or maybe they won't be mammals - octopus and squid are highly intelligent. Heck, even slime moulds have been shown to be capable of solving mazes!On the gripping hand, maybe we've out-evolved evolution? The optimist in me hopes that technology will out-pace the fuse on the genetic timebombs we have become. Maybe medicine will be able to edit our DNA, or write it afresh, truly triumphing over nature?Article stimulated by this BBC blog entry.Other linked news items.

When do humans develop abstract reasoning?

This is a great demonstration of abstract reasoning, and the lack thereof in small children. Apparently kids will (almost) always fail this test up to age 4, and almost always pass after age 7. The magic transitional age varies, of course.Parents and siblings, this should give some great hints on how to seem "fair" while still short-changing your child. ;)

Human Electric Hybrid Vehicle

The HE Human Electric Hybrid Vehicle It looks like an interesting concept car. Although, it might be hard to find somebody who wants to pedal it. I really like the solar panels on top, and how on the downhill, it charges a capacitor for energy.This HE Human Electric Hybrid Vehicle concept uses the power of your muscles as well electricity stored in the batteries. It allows smooth and constant velocity both uphill (with the help of the electric motor), as well as downhill (when the wheel acts as a generator and charges the batteries). The vehicle can turn 360 degrees maintaining stability all the time. Additional power is acquired from photovoltaic placed on top of the vehicle as well as during de-acceleration from regenerative braking. Elderly and handicapped people that are unable to provide enough kinetic energy can also charge the batteries directly from the grid.

Flugtag -- human powered flight?

Have you seen the videos for Flugtag? It looks like a great excuse to build something fun and jump in the water, and maybe fly a few feet too.Most of them look like this: And here's the US record holder, at a whopping 155 feet: I bet we could do better than that, especially with a drop. ;) Anyone have a proposal for Team Instructables? They hold these things around the world, so it's not just US. I bet we could pick up on style points as well.From the official page:The first Red Bull Flugtag took place in Vienna, Austria, in 1991. Since then, more than 35 Flugtags have been held around the world -- from Ireland to San Francisco -- attracting up to 300,000 spectators. The record for the farthest flight-to-date currently stands at 195 feet set in 2000 at Flugtag Austria. The U.S. record stands at 155 feet set in Nashville, TN in 2007.Teams are judged on three criteria: distance, creativity and showmanship. What constitutes a craft is purely up to the imagination of the participating teams. Past Red Bull Flugtag entries have included a pregnant cow, a diaper-delivering stork, a pimped-out Cadillac, a giant Oompa Loompa, and yes folks -- a lobster named Larry.

Human finger model movements DC activated.

Hello good folk I have been working on some artificial finger extensions and retraction via a DC motor. An H-bridge is used which is connected to a dial switch. The tendons are braided fishing line. It has proven worthy during the prototype stage. The advantage of my design is that a single DC motor of servo can control movement and grasping of the entire finger. This design particularly excels when compared to the most advanced models at the moment.... The Shadow hand would be an example. Extremley capable yet the muscle collection to the rear of the hand makes their model obsoliete even before it was created. Much work needs to be done on their model to make it effective. I apologise for the pics (camera phone) as the detail leaves much to be desired. This is just a functional model of the unit, so it's not ment to look pretty. It only purpose is to serve as the concept base as I was trying to get the tendons/joint configuration worked out... You should notice the holes in each section, the tendon passes within the finger segments within a sheath embedded inside the epoxy segment. The tendon is only exposed at the joints which also need to be finished with a exterior protectant layer. I am posting these as an example of the funtioning finger. However I would like to post videos at a later date.

Would this floating idea be plausable?

Basically, I was thinking in my sleep as I usually do. I thought about how less dense things float on top of more dense things. And this got me thinking towards this: Are there any gases that are more dense than the human body? If so, we could float on this particular gas (with gas masks or oxygen tanks of course). This also led me to think about: Are there any liquids which are lighter than air? We could have a swimming pool of sorts that floats on the ceiling. All we would need is the right chemical. Any scientists out there? (I know it is unlikely as states of matter generally mean that in terms of density, Solid>liquid>gas.

Needs updates. www.slida.orconhosting.net.nz I have tried, with my limited financial resources, to market them but my problem is the high production costs and lack of finances. So I have been thinking about giving the idea away for free as an open source hardware design.  I am planning to start a community of people developing the idea and maintaining the design.  My strengts are design and problem solving. I have improved the original prototypes so now the current design has got not many bugs or flaws.  As I got the idea for my UUT from a design in Finland and they no patent either, the idea can not be patented.  And since I have not benn able to commercialize my idea, I am keen to give it away as an open source design. How to go about it?
