Mars as an Iron source?

Could we send something to mars to strip mine the surface and gather all of the iron oxide, then using a solar mirror array direct sunlight onto the days collections and melt them into iron.  Then ship it to earth in a giant iron blob which would be transported by some kind of ship. I assume this either hasn't been proposed or is not practical because I haven't seen anything like it before.

Mars' Winch Rides!

Mars hooked up a winch so he could hoist stuff to the ceiling easily, creating instant ceiling storage space. Of course, we had to test it first. For structural strength.

Living in a box, living in an expensive box...

Four Europeans are in the final stages of selection to be locked into a series of sealed boxes for a year and a half. They are competing for two of the six places in Mars500 - a full-scale simulation of a short-stay Mars mission (a year and a half each way, a month on the surface - don't get me started on how wasteful that is...). The Mars500 facility, which is located on the IBMP site in Moscow, comprises four sealed modules. The total interior volume is about 550 cubic metres. There are no windows. The walls in the living quarters have been covered with a wooden panelling to make them feel slightly less austere. Looking after the participants' needs will be a mission control-room sited just outside the containers. But the experiment's designers are determined to make the training exercise as realistic as possible, so they will introduce a time delay in communications after two months. Because it can take about 20 minutes for a message to travel from Mars to Earth, it will take this amount of time in the simulation also. Message delay The crew and their ground controllers will send text messages to each other and then have to wait for the replies. It means there can be no real-time conversations with friends and family - and, in moments of crisis, it will mean the crew will have to make crucial decisions themselves. I think the biggest test will be the social side - how will six humans, no matter how well-selected, deal with having nobody but each other for years on end, and being in each others' faces twenty-four hours a day? Could we end up looking at the first murder in space? BBC Story ESA article Institute for Biomedical Problems

High Resolution view of Victoria Crater on Mars

NASA has released a beautiful high resolution picture of Victoria Crater (below) taken from the Mars Reconnaissance Orbiter. If you zoom in on the full resolution image, you can see the Opportunity rover's tracks and stopping points (faint lines with bright dots) around the left part of the rim.The photo was taken in July 2009, so many of Opportunity's tracks have already been obscured by wind and sand.

Watch engineers build a Mars rover!

This is super-cool. NASA's JPL has set up live streaming video from inside the clean room where they're building the Curiosity rover, formerly known as the Mars Science Laboratory. Work is from 8am-11pm PDT Monday through Friday. I found this on Saturday morning and I've been waiting all weekend for those slacker engineers to get to work so this would be worth posting. Some comparison: The old Sojourner rover from 1997 was the size of a largeish R/C car. The Mars Exploration Rovers from 2004 that are still running (!) are the size of golf carts. This thing's the size of a Mini Cooper, and has a proportionally larger load of sciencey stuff packed on.

Core Wars: The battle of the programmers.

Okay, brace yourself for a lengthy background story: In the 1960's and 70's, computers were much too expensive for a normal person to have one all to themselves. Before the invention of the Personal Computer (PC), computer systems were mainly employed in large universities, able to be used by students. However, there came a danger with all this: Back then, there was no such thing as protected memory, meaning that someone with minor hacking skills and some knowledge of assembly could easily wreak havoc on other people's data and programs. One such urban legend is that of a major business firm's main computer system, which a mischievous employee had installed his own assembly program called creeper, who's only purpose was to create copies of itself whenever it was run. This soon became a problem, as the creeper virus began eating up precious space in the memory and began corrupting other people's data and programs. After a while, another more brightly-hatted programmer created a program called reaper, which would make numerous copies of itself and destroy any creeper virii it could find and then self-destruct. Soon enough, things were back to normal. After hearing this story, a programmer named A.K. Dewdney got the idea for a game which he called "Core Wars". In this game, people would write computer programs called "warriors" in an assembly language called Redcode. Redcode had instructions not out of the ordinary of any assembly language. These programs were then run simultaneously in a simulated computer called MARS. The aim of the game was to make the opposing program crash by forcing it to execute an illegal command in the computer's shared memory. The surviving program was declared the winner. The absolute simplest warrior was called imp, and was written by Dewdney: MOV 0, 1 The MOV command moves copies a command from one place to another, in a position relative to the MOV command. Because of this, the imp would fill up the entire memory with MOV commands in a relatively short amount of time. Because the memory loops around (So, if the size of the memory is 8000 commands, then command 8001 would be executed as command 0) then it meant imp would always hit it's target eventually if it wasn't hit first. Another program which was written by Dewdney is called Dwarf: bomb      DAT 0,0 Dwarf     ADD #4,-1                 MOV bomb,@bomb                JMP Dwarf End Dwarf This is the first example of a "bomber" program. This program would drop DAT 0,0 (An illegal command) at every fourth slot in the memory in the hopes that the other program would accidentally execute it (cookie if you can figure out how it works). There are far other types of examples, like scanners, which try to scan the commands around it to see if they are illegal. Some programs can even repair themselves mid-battle. So, does anyone else still partake in this ancient game? I recently just got into it, writing my first warrior program a few days ago. Have no idea if it works, but it sounds pretty cool. It's based off of Dewdneys Dwarf but with a few modifications (I named it MindSplitter): bomb      SPL 1                 JMP -1                 DAT 0,0 Split        ADD #5,-1                 MOV bomb,@bomb                JMP Split End Split First off, this plants bombs at every fifth command instead of fourth, which I hope will help it spread out. Second, the bomb it uses is my personal invention that I call the Splitter bomb. In Redcode, the SPL command will jump execution to the specified command, while at the same time continue executing the commands after it. The idea is that the SPL will split to the jump command while the normal execution goes to the jump command, and both of them jump back to the SPL, therefore filling up all of the enemy programs processes. If the enemy program somehow manages to escape the loop, there is a deadly DAT after it. I haven't tried this out yet and I'm not sure how it would do in battle. If someone with a MARS emulator and a warrior of their own would like to put it to the test, I'd would absolutely love to hear how it turns out :).

Distinguish glass hard disk platters from aluminum without marring the reflective surface? Answered

I have hundreds of hard disk platters from disassembled hard drives.  Some are made of glass, some are made of aluminum.  The glass ones, when flexed, shatter into thousands of razor shards which screech across the room. I would like to avoid that in the future.  I only want to use the aluminum ones, but I don't want to mar the reflective surface. I've thought of weighing them, but the platters some from many manufacturers and eras and so the weights won't be consistent.  Magnets don't attract glass or aluminum. Does glass float? (I'm guessing no.)  Is the reflective surface transparent? (I'm guessing no again, but maybe a strong light would work?) There has to be a way....

BIKE REPAIR STAND: How about a low cost, easy to build, bike repair/cleaning stand?

It should hold the bike off the ground and tight so it does not move around while you work on it.  I was thinking of using half inch pipe stuck in a five gal bucket filled with cement, but I could not come up with a good clamp idea.  BTW, the clamp should not mar the paint job.

Drones, not just for spying

So with the advance of 3d printing, arduino firmware, Raspberry pi, and the general open source approach to making things in the last 15 or so years, it's really not that surprising that drones have become as wide spread as they are. Those not interested in drones view them mostly as either a hobby or a potential threat to their privacy, but I had an idea the other day that might push them into better prominence.   What if drones could be used for construction and basic maintenance?  What if a quad copter was the thing that was wiping down the windows of a skyscraper?  Or messing with dangerous high power electrical lines.... Things that are both tedious because they have to be done over and over again, and that are moderately dangerous for a human being to perform.  Why can't a drone be used for some of that, and can one be designed around those constraints?  This is how a hobby user could make innovations that might curtail some of legal and general paranoia surrounding drones.  This is all well and good, but let's take this a step further: Drones are a necessary part of human exploration.  People talk about putting humans on Mars.  Human beings require inputs. Food, shelter, air.... those sorta things.  If there's a problem with one of those things on Mars, there has to be a way to fix that, and it's probably best if it's something that's established before those humans get there.  Drones could be used to do a variety of tasks, and possibly even establish small caches of water or maybe even limited quantities of iron. Maybe even something like a 3d printed iron shelter.... (Induction heating works by pulsing a electromagnetic coil with high frequency electricity, which can be used to melt magnetic metals with high degrees of efficiency. This could be used to make low grade steel on mars, but if time and scarcity of resources aren't constraints... it would work.) Anyway... I was just sort thinking about this stuff. Let me know what y'all think

Problems downloading a PDF - March 2014 **FIXED!**

Mar 21, 2014 - UPDATE We had a small release last night and it looks like this problem was solved! Your browser will require a new cookie for our site; clear your browser cache and refresh the page, then try downloading again. You may have to use the 'custom PDF' on some projects. Thanks for bearing with us while we sorted this out. Please leave your comments below. ---------------------------------------------------------------------------------------------------------------------------------------------- Mar 14, 2014 One of the Pro Membership benefits is the ability to download a PDF of an Instructable for offline viewing. Something has happened in the last week which has caused the PDF generation to not work correctly, preventing projects from being converted into PDFs and being downloaded. This is a known bug and we are investigating the cause and a fix. You may notice this happening to a few Instructables, but not all. There are still many projects that work fine when you request a PDF generation for download. Currently we can recreate this issue across all browsers and operating systems. While we figure out what is going on and working on a fix, please use this Forum topic to provide us with any feedback you may have or links to projects where you're experiencing this problem. Updates to this post when there's more details. Sorry for the delay.

Pro users receiving banner ads?

For a long while, the only ads I was seeing on Instructables pages were internal -- mostly examples of highly rated/featured I'bles, or contest announcements. Starting today (24 Mar 2010), I am seeing banner and sidebar ads.  This isn't a big deal, except that a lot of them have been those really annoying rollover-giant-box type.  This makes it quite cumbersome to navigate on the page, and in particular, to do anything where your mouse has to go near the masthead.

What's the best method for making registration markers for multi-color poster printing?

Currently, I am printing registration marks on my transparencies so that they burn into the screen. Each registration mark is the same for every color. When the screen is burned, the registration marks appear. I clamp the screen, and lower it to print the registration marks, then lift it and cover them with tape. I use the printed marks to line up my paper. This works pretty well, but I am convinced there has to be a better way. Can anyone help?

Less People

In discussions I've had with my father multiple times, we've come to the conclusion that for humans to stop having a negative impact on the planet, there must be less of a human population. No other way around it. Now, don't get me wrong and think I'm saying everyone should commit suicided or someone should make some deadly disease to wipe out massive chunks of the population, I'm just looking for others opinions to this theory and possibly other.... more humane alternatives. Other ideas as to reducing human population on earth: Sustainable colonies on the Moon, Mars, etc.?

Hi all, I've got an opportunity to lay hands on this sweet wifi webcam: Thing is, I've already got one monitoring my 3D printer, and I'm not exactly chomping at the bit to spy on my roommates when I'm away.  I've got a couple ideas about what to do with it, but I thought I'd throw it open to the community:  got any cool ideas for interesting ways to use/alter/hack/repurpose something like this? Currently I'm considering tearing into it and using the remotely controllable pan and tilt motors to turn it into a mars rover for my house, possibly fitted with a laser to annoy my cats.  What do you think? Ian

Where U At?

I know that the USA, Canada, Mexico, Argentina, UK, Australia, and New Zealand are all represented on Instructables. What other countries are represented? Are we in all seven continents? (give or take Antarctica, since only scientists and penguins live there). How many of the states of the USA are here? What's our membership by country? Is our membership only limited to earthbound beings, or do we have any astronauts or other in the ranks? Are all of our members even human? You have answers, post 'em. Just put something like "Texas, USA, here", or "Gusev Crater, Mars, here".That way we know where we're at After that, plot your location on the membership map.

If you could...

If you could... Spend an hour anywhere in the universe, at any point in time, where would it be? Meet 5 different people, from any point in time, who would they be? Have any one "superpower," what would it be? For me: Place: Mars, about 70 years ago. People: 1) Ernest Chappell, actor on Quiet, Please!, a 50's radio show. 2) Wyllis Cooper, writer for Quiet, Please! 3) Eoin Colfer, author of the Artemis Fowl series. 4) Ernest Emerson, founder of Emerson Knives and the Emerson Combat System. 5) Mikkel Maltha, the keyboardist/ bassist/ backing vocalist for the Danish band CRYOSHELL. Superpower: The ability to alter my molecular density, rather like Seth's in "Race to Witch Mountain" What would you choose?

Resin floor

Has anyone ever done a DIY resin floor? Any advice? A friend of mine is in the early stages of a plan to cover her stairs in resin, with embedded small pieces of tile left over from the kitchen. We're planning to do a lot of small scale testing before we actually do anything permanent, and were just going to start with harware store marine resin. At the moment, the stairs are the bare chipboard left when the gross carpet was removed. It also curves around almost 180°, so there are only a few rectangular stairs. Any tips on the type of resin to use, best way to build a stair sized mould, things that the resin won't stick to, curing time, or any other random advice would be appreciated.

Just thinking for extracting and re use them in my project. I am planning to get them even if I buy, but i couldn't find them in one web-store, I have to buy them from different stores this will make shipping cost so high for my budget.

Isn't it written in stone that you have to put more energy into water than can be extracted from it?

I can see how astronauts could need oxygen from water on the moon, but haven't we always been told it takes more energy to separate the molecules than can be gained from burning them? In reply to a response from my last question, I referenced something I read a long while back. It was about deep space probes extracting water from Mars or other planets and using it for fuel to go even further (faster I'm assuming). So sure, astronauts need to breathe, and would be able to recoup some of the lost energy  from the hydrogen, but how would an unmanned space probe benefit from such a loss of energy?
