Satellite images.

Does anybody know where i can get highly detailed satellite images? Higher than google. Google has this thing that you can pay $20 to get better quality, but to me that seems like a rip off. Anyone know any places to get better pictures? Thanks

How to build your own Sputnik

It seems incredible that the technology that went into building the first successful satellite 50 years ago can now be found lying around the average house. You could even build one yourself, as Paul Rubens explains below. Fancy having a go?http://news.bbc.co.uk/2/hi/uk_news/magazine/7049002.stm

Looking for more info on dish actuator

I received a free actuator from my friends cottage. 11 years ago it use to angle a 8ft dish. It was removed some time ago, and the label is fully off. The bottom says its a saginaw performance pak actuator, aka PPA, and it has a 24" arm. I was trying to find more information on it, and all I can find is that it can be heavy, regular, or light, 600-1,500 pounds dynamic linear. Anyone have one or any ideas? I cant find a model number on the case cuz it faded, but the motor says 7821645 or 1821645. Either way I found a tiny chart listing models but not that one.http://www.galaxy-marketing.com/images/7822260.jpgLooks similar to that one there. I just want to find out how much force it has. Most I done so far to test it works aftter 11 years of rusting on the main shaft (the moving piston is fine) is sit on a box. It manage to push me with no change in motor sound. Any more details? Please ask!

Space Trash Crowds Orbiting Satellites

Two or three times a day, a satellite circling Earth narrowly misses destruction by an orbital hailstorm of junk sweeping the busy super highways of space.A spreading cloud of shrapnel from the collision of two satellites earlier this month is making wrecks for working spacecraft around Earth all but inevitable, analysts warn. As the ninth significant crack-up in two years -- including a punctured nuclear satellite -- the wreckage of Iridium 33 and Cosmos 2251 is fostering a chain reaction of collisions that puts billions of dollars of spacecraft and manned space flights at risk.Full article and really cool slideshow: Harmless Debris on Earth Is Devastating in Orbit - Wall Street Journal.via benjaneer.

Kids Chalk Drawings = Satellite Photography Hacking?

The Kid's Chalk Art Project out on Alameda Point, CA is attempting to break some sort of sidewalk chalk drawing record. That, granted, is mildly ammusing.However, what is really interesting is that they are having a satellite picture taken of their work on Saturday, June 7. So, if you have anything you want to write really big in that general area, now would be the time do it. Thanks Tim!

Satellite to Radio to Pneumatic Valve

I want to receive some sort of satellite signal with a radio and then use the data I receive to control a pneumatic system to replicate a heart beating. I have been talking around with some people who know a bit about radios and the such but haven't gotten much conclusive help.  I would like to build as much of this as I can myself, the entire radio and everything, though I only have about a month to do it. A DIY radio kit paired with an Arduino might be the answer due to time restraints.  What i've learned so far is that I probably want it to be a tunable AM radio. Whether or not I should build that myself from scratch, build a DIY kit, or just purchase one, I am not sure. How to then interface that into a system to then control a pneumatic system, I have no idea other than the obvious arduino. Lastly, I don't need any special signal from the satellite. I really just need to receive a voltage from the radio. Though, hooking into a satellite with an onboard atomic clock so that i can then display the time as well would be great. I am going to keep doing research, though if anyone here can lend a helping hand I would be very appreciative!

Would you like your own satellite? (Contest with $1500 prize)

Oh the joy of Twitter!  I just found out about this very cool contest from Discover Magazine via BoingBoing: Imagine having your own personal satellite orbiting the Earth. It’s got cameras and sensors galore, and you can use it to run experiments, take pictures, and even beam messages back to the blue marble. Well, that geek fantasy will become a reality if the ArduSat project, which you can see here on Kickstarter, reaches its funding goal. The general public will be able to rent time on this small satellite and use it for whatever they please, courtesy of its Arduino processor. [The folks] at Discover Magazine think this is pretty neat. And [they'd] like to give away a development kit worth $1500 to the Kickstarter donor who submits the best idea for an in-space experiment before July 15th, 2012. The kit includes Arduinos and an advanced sensor suite shipped to your home address, as well as one week of up-time on the satellite to run any experiment. You’ll be able to build the experiment yourself and have it be sent up on ArduSat when it takes to the skies. Here’s what you have to do to enter the (drumroll) Discover Space Challenge: (1) Fund the ArduSat project, for however much or little as you desire. You’ll receive a personal code that identifies you as a donor. (2) Read the contest guidelines here to learn about how you should design and submit your idea. (3) Enter with this entry form, making sure to include your personal code. (4) Wait for winners to be announced on July 20th, after judging by Discover blogger Phil Plait, Discover Editor-in-Chief Corey Powell, and an expert panel of judges. (5) Rejoice!

Watch out for falling satellites

Watch out for falling satellitesWith no one at the wheel, should we be worried about the large US spy satellite now headed for a crash landing?US spy satellite 193 is predicted to de-orbit less than gracefully in Feburary or early March. The chances of it actually hitting a populated area are exceedingly small, but perhaps you can catch a few micrograms of it using Kiteman's How to catch a star Instructable.What is happening?An out-of-control US spy satellite will crash to Earth in the coming months, government officials say. The satellite is large enough that remnants are likely to survive atmospheric re-entry and strike the Earth, sometime in late February or early March, says Gordon Johndroe, a spokesman for the National Security Council.Is that normal?"This is relatively routine in that satellites de-orbit all the time," says Johndroe. Pieces of uncontrolled debris heavier than two tonnes -- mostly discarded rocket stages -- crash to Earth as often as once every three weeks, says Jonathan McDowell, an astronomer and launch observer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.Many discarded pieces retain some power, so that controllers on Earth can guide them to a point far from human habitation, usually using a final dive into an ocean. In 2001, Russian space officials broke up the old Mir space station in this way over the South Pacific. That's not the case for this US one, however."Obviously, we want to take a look at the potential for it to land in a populated area," says Johndroe.What are the chances of it crashing through my roof?Exceedingly slim, says McDowell. Remember that some 70% of the Earth is water, and most lands are void of people. "There is no reason for people to get alarmed about it," he says.According to the NASA Orbital Debris Program Office, there have been no confirmed instances of serious property damage or injury caused by crashing debris in 40 years.

mission of sputnik 1

Russian technology satellite. One launch, 1957.10.04. Tikhonravov's 1.4 metric ton ISZ satellite was to have been launched by the new R-7 ICBM as the Soviet Union's first satellite, during the International Geophysical Year.    But it was not ready in time, so Korolev hurriedly developed Sputnik 1 as a replacement. It became the first artificial satellite of the earth. Sputnik 1 had 1 watt of power, producing an 0.4 second duration signal on the 7 and 15 m bands. Four antennae were deployed at 35 degree angles. Power was provided by three silver-zinc batteries. Thermo-regulation was by a ventilator. The 580 mm sphere had a mass of 83 kg and was made of highly polished Aluminum AMG6T alloy 2 mm thick. It was built without drawings due to the quick time schedule. Korolev was everywhere, supervising all aspects of its construction. It functioned for 21 days.      AKA: PS-1. Gross mass: 84 kg (185 lb). First date: 1957-10-04. Number: 1 .     the word sputnik is russian word for traveller

DTV Don't be fooled!

Just an announcement. I believe that, as an instructables member, I have the duty to share this info. Some people may, and probably, already know this. CABLE/SATELLITE subscribers will NOT BE EFFECTED. There are a lot of news and ads going around scaring people that their TVs will go black on midnight Feb 17, 2009 if they do buy DTV tuners. I am just worry that a lot of people are gonna be cheated b/c they are not explicitly saying (or warning) that this will not effect cable/satellite subscribers, only those that use local public broadcasts (antennas). OK. Now spread the news! *If this announcement has help you please BUMP this topic (since others may still be fooled)

What Version of HDCP Does the Xbox 360 Require? Other HD Questions...NERD ALERT!

I might get an Xbox 360 some day (say I win the lottery). My HD TV has support for version one of HDCP (High Definition Content Protection, supposed to protect against copying, yeah right). Is version one sufficient to use an Xbox 360 with my TV? Also I only have one DVI port on my TV, no HDMI (it's two years old, my dad kinda jumped into it). We have our HDTV Star Choice satellite receiver hooked up to that, so I don't wanna have to swap out the satellite for the 360 everytime I wanna play in HD (I have a CRT TV in my room which I usually play games on). Can I get a Y shaped switcher thingy for my TV? I know DVI, unlike HDMI, doesn't support all in one audio and video in one tiny HDMI cable. Does the 360 have a seperate output for audio, too?

Video in the ads is killing my bandwidth!

I know instructables pays the bills with targeted ads. That's cool, and useful. No problems there. The problem is putting a 5 minute video in the ads. That gets downloaded when I look at an Instructable. I'm on a satellite link, and my bandwidth costs me quite a bit. If I'm going to have to pay to download a video to look at an Instructable, I either won't look at it, or I'll install ad blocking software. If I want to look at videos I'll go to Vimeo, or YouTube.  Don't let poor choice in ads drive away the users.

DIY Space Exploration

Hi guys, I heard about a guy here thinking about getting a payload into space on DIY terms.Running with the idea, it turns out that commercial off-the-shelf satellite space will run you about 8 grand.Moving away from rockets, the MAKE: team managed to use 'weather balloons' and helium to hit 109,000 feet. (http://blog.makezine.com/archive/2007/03/diy_space_make_video_podc.html)My idea/question in this.If you can get a payload near space, what if your payload is a small rocket that fires at the peak height, could you drag something (kicking and screaming) into orbit?Thoughts and discussion here, I'm really excited about this!ParadoxDetected :)

Solid State Sensors? (Very Edited)

What properties of an environment can be measured with solid state sensors? Specifically, I am thinking of a project requiring a suite of sensors-on-chips that can measure their immediate (dry) environment and pass the data to a control unit.So far, I know of temperature, magnetism, radiation, acceleration and light (a camera chip).Are there any other (reasonably priced) solid state sensors, and where could I find them (either new, or reclaimed from something else)Edited:OK, so I thought I could be vague about my questions and then surprise everybody with a working satellite.Turns out I'm not so clever as I thought.I'm trying to recreate Sputnik on a tiny budget. Something that could be made by Joe Public, without having to rely on grants or Lottery funding.Sputnik weighed nearly as much as I do, but all it did was measure temperature and pressure, then send beeps that changed if the temperature or pressure went outside a certain range. I know it has been outdone by students with CubeSats, but they still cost tens of thousands of dollars.I thought that it should be possible to recreate (and out-do) Sputnik's capabilities on a single board, a simple programmable control chip taking in the data from a set of sensor-chips encoding it somehow, then passing it to a transmitter to be beamed to Earth.I thought - still thinking micro-budget - that the whole thing could be cased in a short piece of sealed PVC tubing, since PVC is radio-transparent.In my head, in fact, the satellite looks like a relay baton, but shorter.Am I being stupidly optimistic?

more powerful, portable amp

I was messing around with some op-amps, building variations of the CMoy amp, etc. But I became depressed quickly -- these ICs' data sheets say that at the safe maximum of 15 volts, they can only pump out around 1/4 watt of power on a single channel! Well, i have a full range driver that really needs more power to sound decent. I was wondering what the normal way of constructing an amp would be if I were looking for 5 to 10 watts of power. *edit*: i'm not looking to run this thing off of batteries... i'm sure at 10 watts, a couple of D cells would get drained rather quickly... I recently cracked open an old 4.1 computer sound system (by microlabs) and scrapped the 5 drivers (4 satellites and a 5 inch sub), two big 3700 uF caps, and two JRC4558D dual op-amp ICs from the amplifier. I read up on the JRC chip (actually, just the data sheet from the RC5448D, the texas instruments flavor, i guess the JRC is discontinued) and it seems that this thing only puts out a max of 200 mW per channel, and typically around 90 mW. Ok i know those speakers didn't get THAT loud without distortion, but i am CERTAIN it was more than 800 mW for those 4 satellites. I am a new computer engineering student, so i can understand the physics behind the electronics, but i am nowhere near the level to start reverse-engineering that amp board. So how did these speakers get driven so hard? THANKS for reading!!!!!

Using the IRDA port on my toshiba satellite 2520cds

I got this old gem a month ago from a guy that recently and obviously needed a new one, but it worked this long surprisingly for power points. I must admit that it runs decently fast with xp and not having turned anything but system restore off. It's got a 333mhz amd 3D processor which I want to try upgrading with a k6 down the road as it IS removable. 96mb of ram and a lousy 4gig hd that slows the whole system down. But that is barely important. I had a swell idea of utilizing the irda port on the back for controlling it via a tv remote or any I might have kicking around which I have plenty of. Also, I wanted to be able to CONTROL my tv, vcr, dvd player, ect with it in itself aswell.Google didn't help me much this round as apparently there is software (which I did try) avalible but it's meant for home made or certain commercial infrared ports that plug in via serial, usb and perhaps parellel that I saw. I also saw a hint of what seems to be that the built in irda sensor in most laptops aren't able to receive commands from most remotes for learning or controlling it due to the filtered out bands. But they are supposedly capable of sending commands just fine. Now this is a OLD OLD laptop and there could be a chance that it can receive the commands too? Even still, you could pull it apart and modify the sensor to accept signals couldn't you? I'm looking for something to do with this laptop and this seems perfectly suitable for it as the screen is older and has that "motion blur" effect to it and so makes playing nes games a bit hard :-P. Sorry for the long post, but hey, if someone could help me with this, it would certainly make me happy.

Making a cheap cheap projector?

I know that it's possible to crack open a "oldish" laptop or even a new one and remove the shielding around the lcd itself and shine a special light through it that's bright enough where you essentially make a lcd projector. I have a old toshiba satellite 2520cds with specs like a 2mb vid card, 96mb of ram, 4 gig hd, and a 300mhz amd processor. It runs somewhat fast, even for windows xp that I installed on it and plan to upgrade the hd down the road, but I wonder, would I be able to do the same thing with this? The screen is an older lcd that has that "motion blur" effect to it, so would it be worth it? Is there some way I could connect this lcd to my video card on my pentium 2 I have that would allow me to actually watch movies?

Record Solar Powered Flight

UK-built solar-powered plane has set an unofficial world endurance record for a flight by an unmanned aircraft.The Zephyr-6, as it is known, stayed aloft for more than three days, running through the night on batteries it had recharged in sunlight.The flight was a demonstration for the US military, which is looking for new types of technology to support its troops on the ground.Craft like Zephyr might make ideal platforms for reconnaissance.They could also be used to relay battlefield communications.Chris Kelleher, from UK defence and research firm QinetiQ, said Unmanned Aerial Vehicles (UAVs) offer advantages over traditional aircraft and even satellites."The principal advantage is persistence - that you would be there all the time," he told BBC News. "A satellite goes over the same part of the Earth twice a day - and one of those is at night - so it's only really getting a snapshot of activity. Zephyr would be watching all day." The latest flight was conducted at the US Army's Yuma Proving Ground in Arizona.The Zephyr flew non-stop for 82 hours, 37 minutes.That time beats the current official world record for unmanned flight set by the US robot plane Global Hawk - of 30 hours, 24 minutes - and even Zephyr's own previous best of 54 hours achieved last year.However, the Yuma mark remains "unofficial" because QinetiQ did not involve the FAI (Federation Aeronautique Internationale), the world air sports federation, which sanctions all record attempts.The US Department of Defense funded the demonstration flight under its Joint Capability Technology Demonstration (JCTD) programme. The 30kg Zephyr was guided by remote control to an operating altitude in excess of 18km (60,000ft), and then flown on autopilot and via satellite communication.It tested a communications payload weighing approximately 2kg.At first sight, the propeller-driven Zephyr looks to be just another model aircraft, and it is even launched by hand. But this "pilotless" vehicle with its 18-metre wingspan incorporates world-leading technologies.Its structure uses ultra-lightweight carbon-fibre material; and the plane flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper. These are glued over the aircraft's wings.To get through the night, the propellers are powered from lithium-sulphur batteries which are topped up during the day."A lot of effort has gone into power storage and light-weighting the systems," explained Mr Kelleher. "Lithium sulphur is more than double the energy density of the best alternative technology which is lithium polymer batteries. The engineers from the Farnborough-based company are now collaborating with the American aerospace giant Boeing on a defence project codenamed Vulture.This would see the biggest plane in history take to the sky, powered by the sun and capable of carrying a 450-kilo (1,000lb) payload.US commanders say the design must be able to maintain its position over a particular spot on the Earth's surface uninterrupted for five years. QinetiQ is the public company that used to be the British Government's military research department, before they privatised it.BBC articleQinetiQ's page on Zephyr

Look here if you need Ideas!!!

Lots of people are asking for ideas for instructables. Here's a few ideas that might give you a new idea. If you have any ideas, post em here, so people can hopefully make em.Tech:* As suggested by Redrev: Take a DVD-Player/recorder that the DVD drive has died and take the tuner and video hook ups along with lcd screen(that shows the channel and dvd section numbers) and connect to the computer to watch t.v. and dvd's ala win-tv.Climbing Robot- a robot that can climb a little stairs of books or something. Or at least crawl.A model of an elevator- you know, you hit a button on a remote, and the elevator rises to that level.Model Train- one of those little trains. Would be cool to learn how to make one.Model Forklift- Its basically an R/C car, but can anyone make it lift a little notebook?Pencil Sharpener? (Electric)Introductions - Theres a lot of big words out there, but most of us have never heard of em. If you're good with something, why not shre your knowledge?FlexinolsmtOffBeat:Weird Uses for satellite dishes- I've noticed how many thing you can do with old satellite dishes. Be creative!Naruto Costumes and accesories (not paper)Dragon Ball Z style effects with smoke- how about pressurizing fog or something to have it shoot out of a tube? Would be neat.A DS Game CaseArtHow to draw Anime Hands- personally I find that hands are the hardest thing to draw. Maybe someone has a little trick to get em right?Bridge of toothpicks- Its a bridge made or little wooden sticks that can hold a grown man. I've seen it in a lot of science fairs, and it would be neat to learn how to make em.As much as I hate myself for doing this, yes this is another post of an old topic I had. Just saying it before anyone else.

DIY Bluetooth speaker build, advice please

Hi all Apologies for the newbie questions, I've decided to build my first portable speaker system. I was hoping to make my own version of the 'Vintage Audio Suitcase Speaker' e.g. www.vcase.com.au I have found some second hand 6.5 inch 'Response' woofers for a cheap price and I have two spare satellite speakers from my Logitech Z-5500 system. Suitcase should be relatively easy to source. What I'm struggling with is the amp and battery choice. I'd like this to be able to run for a few hours on battery, and be easy to recharge via mains or USB. I don't mind spending a bit of money on the amp as I'd like this to last a good few years. The tricky part is, with my current speaker plan, it would need to run 4 speakers that are rated at 70wrms each. Plus the Logitechs are 8 ohm and the Response woofers are 4 ohm. Is this possible? Advice much appreciated.

MGS5's iDroid - Can it be Built with Open Source Tech?

I can't get enough of Metal Gear Solid 5! It definitely deserves the 10/10 scores its received! But as cool as it would be to have a giant robot or even a Walker Gear that you and/or your enemies can pilot, I think the coolest thing to have from the game would be the "iDroid". If you havent played "The Phantom Pain" or "Ground Zeroes", the iDroid is a device Snake uses for multiple purposes. Some include: sending radio trasmissions and calling in supply drops or helicopters between the iDroid's location and Mother Base, Displaying a topographical satellite view of the area Snake is in, Organizing Mother Base staff, resources, R&D; projects, and playing music from cassette tapes found while on missions, Just to name a few. (bold font is to differentiate the uses) So is it possible to build a similar device using the open source technology of today? (minus the use of cassette tapes and a 2D holographic projection screen) I'm pretty confident that it can be done, but what do you guys think?

Reinstalling GPS Drivers During Hardboot on o2 XDA Zest phone to out of box factory settings

Hi, I use my old o2 xda zest phone evey day as it has an usefull inbulit gps system that i use for navigating the roads that i'm unfamiliar with.  I feel the gps drivers may have become corrupt as the phone tends freeze for a few momentst until a strong satellite signal is received.  I want to return the phone back to its original just out of box factory setting by hardbooting the phone. Before i begin  I want to ask!  If i hardboot my windows mobile xda zest phone are the drivers for the inbult gps receiver automatically installed during the hardboot or will i need to down load them from the web later to install them?.  Im asking since i dont want to perform a full hardboot to discover my gps drivers on my phone have been lost forever !  Have you hardbooted your xda phonein the past.  please let me know. Thanks for replies in advance.

MGS5's iDroid - Can it be Built with Open Source Tech?

I can't get enough of Metal Gear Solid 5! It definitely deserves the 10/10 scores its received! But as cool as it would be to have a giant robot or even a Walker Gear that you and/or your enemies can pilot, I think the coolest thing to have from the game would be the "iDroid".

(minus the use of cassette tapes and a 2D holographic projection screen) I'm pretty confident that it can be done, but what do you guys think? (btw i also have the same topic in the Tech section, cuz i figured that would fit well probably)

The Information Revolution -- Perhaps we're too connected?

Being a target victim of a hacker, I suddenly came up with an emergency protocol (Emergency Protocol 06) which involves computer scans, network disconnection, pass code implementation, security questions etc. Now several hours afterwards, I started to think about the dangers of the information highway, as perhaps we're speeding a bit too fast, end up in a high-speed crash and all that. Then after that, I asked myself, "What if this highway were to blow up?". That being the crashing / destruction of all or at least most of the servers in the world. All of the information, connections, gone. Sure, the satellites serve as a sort of backup cable, but really, it's not enough for the world to use. Hell, the only reason the Philippines has any internet is one, tiny, undersea cable from Japan. Not exactly tiny, but it's the reason why our "fast speeds" are just painstakingly slow to the more developed countries. This is more of a survival question, after a post... post... I don't know. Won't be really post-apocalyptic, but it is suckish and all communications gets cut around the world. If it were to happen, what will you do? Oh yeah, don't post stuff like "that's impossible" or improbability whatnot. It's a theoretical situation that is highly unlikely to happen, but if it were to be...

WIFI Mapper

Hey All! I'm a frustrated guy when it comes to Wifi. I can never get the hang of where to position my notebook in the room to get a decent signal. The worst of all is that the best wifi spot in the house is subject to change all the time. Maybe it's the microwave being on, someone on the cordless phone, etc. I'd like to make the Roomba use a gradient descent algorithm to find the best place in the area to position my laptop, or any other 802.11a/b/g/n enabled device. That way, I can let the Roomba spin around a room for a minute to show me where to best sit down. I believe this capability of Roomba will be both easy to implement, and highly useful. In fact, by being able to export a map of the local wifi signal in an area, college/workplace admins would better find out where to position wireless access point and repeaters. WarRoomba-ing, anyone? Please use your powers for good and not for evil ; )s In my deign, I could see a whole host of like minded applications - best radio/TV signal, bluetooth, best WiMax, Satellite, best...you name it. Right now I am focused on WiFi, but I am looking into feasible TV/radio methods, too, since my TV reception is AWFUL! (Worse than Wifi, but not used as heavily). This will be my first Instructable, and I am anxious to get started!

What would happen if the Internet were to fall?

With all the terrorism stuff going on, I've always wandered what would be next.Ever since 9/11, I always asked myself were they would strike next, because they certainly did not intend to stop there.My guesses have been that they would probably strike at either:1) Elections - Either at the thing were they welcome the new president (sorry don't know much bout U.S. polimatics)2) Beijing Olympics - Its an important event3) Internet:I came to realize that one of the worst things that they could do was attack the internet. I figured that one of these methods could be used:Multiple malware methods. They could attack individual computers with wormsSomehow attacking diffrent countries methods of connection, being either telephone companies or whatever other methods they use (like those China underwater tube things)* But my best guess would be that they would strike important service providing companies. They would destroy the companies methods (satellites, cable mainframe stuff etc...)I would like this forum to have the porpose of disscussing terrorism issues and future issues like oil and so on. But mainly, what would happen if somehow, they attacked the internet?Sure hope none of them read this, cuz if they didn't have this idea, now they would....P.S. sorry, Im nt good with techie, so some of my points may not me accurate or clear. Please correct me if needed

Instructables the movie

I'm calling the attention of all the Instructables Team and Community, together with your suggestions and comments, we can make a very beautiful, suspense, breath-taking movie. I know that Macgyver blockbuster film is coming and it has a very big budget. I'm hoping that Steven Spielberg will help us in this regard. Let's make an exciting story. This movie is about invention, innovation, recycle, gadgets, espionage, robots, gizmos, diy, computer whiz, Macgyverism, hacking, satellite, homebrew, offbeat/sneaky/wacky uses of everyday things, problem-solving, strategies, smartness, creativity, etc. Let's start for example with a fourteen-year old boy who is an instructable freak. He unexpectedly witness a crime scene where the "big brothers" (mafia, yakuza, terrorists, NSA, CIA, etc.) are involved. A conspiracy came out to eliminate him. He is now running for his life. His only tools are his "mossad" skills/talents and the "smartest instructables." We can develop further this story by the following steps: 1 - Identify the problems which he will encounter to survive 2 - Select smart solutions from instructables 3 - Integrate and converge those situations in each scene 4 - Choose characters for the movie 5 - Let's make a script 6 - Finalization 7 -Dr. Eric Wilhelm, please contact the Hollywood... Are you with me? List now the links of your favorite instructables that can be used in this movie! And join the forum... http://www.perixgenius.co.cc

Radio Triangulation (GPS minus space)

Okay, my idea is that in the event of the zombie apocalypse (or many others) I think it would be very handy to have a GPS-esque service.  I've read that the satellites we use for GPS are decaying and will not be around for much longer than 20 or 30 years without repair or replacement.  So, in the event that the zombies come and I manage to survive and, more importantly, thrive, I would like to be able to set something along these lines up. Assuming I have access to renewable power sources and the correct materials, how would I build something like this?  My initial thought is to use radio towers for triangulation.  I go to three existing radio towers, set them up with a power source, and set them to frequencies A, B and C respectively.  Then i have a (preferably mobile) device that monitors the signal strength of those towers.  Another option that springs to mind is that i might have multiple antennae that i can connect to a few feet of wire each and place around my device for added accuracy. If my idea is sound, I then will have a way to tell where i am, roughly. Of course, not only will I need a method of recording locations in a logic manner, I also have to worry about the accuracy of my readings, due to the limitations of my device/radio towers, possible weather conditions or even my physical location (valleys, cliffs, etc). I should add that I'm looking for a very simple reproducible device here, not a standard GPS with loaded maps or the like.  I'm fine with having a receiver and a notebook for locations, or just marking them down on a physical map.  I don't know much about radios or GPS, I'm afraid, and would greatly appreciate any advice.  Thanks!
