Water-saving toilet hack

Toilets use fresh water, and lots of it.  Sure, you can buy a low-flow model, but you're still flushing with a (smaller) quantity of fresh, otherwise drinkable water. Gregorylavoie decided to get double use out of that water by hacking his toilet.  It's a neat, reversible modification: after you flush, you use the clean, incoming tank refill water for handwashing.  Your slightly soapy hand-wash runoff fills the tank, and is saved for the next flush.  It's a simple, ingenious way to save water with little to no effort. What do you think?  Would you try this mod on your toilet? This post has been sponsored by Pepsi.

Tweezers? What the world is THIS thing?

Ok, I acquired a small interesting device that kind of bothers me as to what the world it is. I have been to the Kandykastle site to see what they carry (the only words on the device save for the batter number and voltage,  and "Made in Japan"). It acts like a pair of tweezers, but the end the touches is rounded (see pictures) and when closed the "button" midway down the handles turn on a RED LED which illuminates the one side of the hollowed out "pincer" portion. I am ASSUMING it has something to do with candy (the name makes that seem pretty obvious......does anyone know off hand?

The Hackaday Prize 2015- save the world and go to space! Really!

OK all you engineers, makers and tinkerers- The Hackaday Prize 2015 has begun! Win a trip to space (or $196,883 in cash) plus over $500,000 in other prizes! I know people here on Instructables are the super creative type of folks that would kick butt in this competition and I'd love to see an Instructables member go to space (because that would be awesome and Astronaut looks pretty cool on a resume.) I took part in it last year and it was a ton of fun and I learned an awful lot by reading through all of the other projects and discussing ideas with other contestants. I also got a lot of ideas for future instructables... :) Your mission this year is to save the world! The devices that inform our daily lives were science fiction in decades past. The barriers that once required giant companies to produce such marvels are starting to crumble. Now, one person with one idea can revolutionize the way we live our lives. Be that person. This year Hackaday is issuing a call to hackers, engineers, makers, and hardware startups from all over the world to focus their creative efforts on solving serious issues that face humanity. The global water crisis, pollution, climate change, food shortages, fossil fuel dependency, and many other big problems are waiting for new solutions.

Transition to a Post-Industrial World

Our friends at the CIRCUS Foundation would like your help, in the form of a few paragraphs speculating on our post-industrial future.You're obviously the perfect people to weigh in on this topic - Instructables is full of green, reusable, energy-saving, upcycling projects, so you're definitely in the headspace - so what do you think the future will look like? Share your ideas in 500 words or less.From the original post: Bridges to the Post Industrial PlanetOur future well-being requires that in twenty years' time we should be living in a manner that differs markedly from the way we've lived in the past century and a half. It seems likely we'll consume less energy, use physical resources more sparingly, moderate the waste we generate, make fewer long journeys, rely more on local produce, repair things we'd currently replace, share objects we might currently own. Other implications are less obvious but potentially significant. Will be the role of corporations change? How will our societies be governed? What civil liberties can we expect?The better we're able to imagine a post industrial world, the better we can identify the barriers to getting there and prepare bridges to get over them. CALL FOR SUBMISSIONS We're inviting people to write a few paragraphs, no more than 500 words, outlining the greatest difficulty you think we face in making the transition to a post industrial world. This might be a technological issue, a cultural barrier, an economic factor or something else. If you have ideas about how the barrier could be overcome go ahead and outline them too.Send your submission to open@CIRCUS-foundation.org along with a couple of lines about who you are. The results will be compiled in a book that will be published free on the web and form the basis of a seminar to be held in London later in 2008.

The World is a Complicated Place: "Eat whale and save the planet" - Norwegian lobby

This strikes me as laughable, but at least the issue is being properly framed. "Eat whale and save the planet" - Norwegian lobbyBy Alister Doyle, Environment CorrespondentOSLO (Reuters) - Eat a whale and save the planet, a Norwegian pro-whaling lobby said on Monday of a study showing that harpooning the giant mammals is less damaging to the climate than farming livestock.Environmental group Greenpeace dismissed the survey, saying almost every kind of food was more climate friendly than meat.The survey, focused on whale boats' fuel use, showed that a kilo (2.2 lbs) of whale meat represented just 1.9 kilo (4.2 lbs) of greenhouse gases against 15.8 for beef, 6.4 for pork and 4.6 for chicken."Basically it turns out that the best thing you can do for the planet is to eat whale meat compared to other types of meat," said Rune Froevik of the High North Alliance, which represents the interests of coastal communities in the Arctic."Greenhouse gas emissions caused by one meal of beef are the equivalent of eight meals of whale meat," the study said.The Norwegian-based Alliance said it was the first to measure the "carbon footprint" of whaling. Fish and seafood was comparable to whale meat with relatively low emissions.Norway and Japan, the two main whaling nations, are seeking new arguments to promote whale meat after years of condemnation from anti-whaling nations for breaking with a 1986 moratorium on all hunts meant to save many whale species from extinction.Oslo says, for instance, that the small minke whales it hunts are plentiful in the North Atlantic and that a 2008 Norwegian quota of 1,052 animals will not harm stocks. The meat is eaten mostly as steaks or in stews

Going green : Saving the planet project : Come here !

Hello everyone. Looking at the rising of all the awareness programs of saving the planet and going green. I thought why not we here at instructables could gather and make a small team of engineers, electricians, high voltage people, hobbits, and project builders to share ideas on how to save the planet and go green. the main purpose of this topic is to discuss and design new gadgets, machines and mechanisms to save the planet to carbon emission and use of fossil fuel. So if you have a idea people over here could evaluate it and try to test is out......who knows it could be a future source of energy to the world. So your ideas and suggestions are welcomed.

Fuel economy of the world's longest in-service ship

The Emma Maersk is the second longest ship in the world, and the longest currently in service. It's so large, it looks photoshopped into any picture it appears. Driving such a large ship requires a lot of power. From Wikipedia:The Emma Maersk is powered by a Wartsila-Sulzer 14RTFLEX96-C engine, currently the world's largest single diesel unit, weighing 2,300 tons and capable of 109,000 horsepower (82 MW). The ship has several features to protect the environment. This includes recycling the exhaust, mixed with fresh air, back into the engine for reuse. This not only increases efficiency by as much as 12% but also reduces engine emissions. Instead of biocides, used by much of the industry to keep barnacles off of the hull, a special silicone-based paint is used. This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicone paint covering the part of the hull below the waterline is credited for lowering the water drag enough to save 1200 tons of fuel per year.We started talking about energy consumption after watching a practice version of Saul's upcoming E-Tech Keynote, Energy Literacy, and Dave Culp of Kiteship and Speed Sailing did a back-of-the-envelope MPG calculation for this ship:A few more facts about Emma Maersk:Running at her rated 80 Mw, her main engines burn 14 tons of residual fuel each hour. Annually, that's 97,400 tons of fuel. Her auxiliaries, delivering their full 30 Mw, burn an additional 6.6 tons/hour, for a total fuel burn of 20.6 tons/hour. Given 290 steaming days/year (80% capacity factor, which is conservative), this yields a total annual usage of 143,400 tons or about $64.5 million in annual fuel costs.Burning 20.6 tons/hour = 6724 gals/hour. At 31 kts/hour, this equals .0046 nautical miles/gallon. At 6076 ft/nautical mile, that's 28 feet/gallon of fuel burned.The 1200 tons saved by her "revolutionary" bottom paint represents a bit less than 1% of this cost, so increases her fuel mileage to 28.2 feet/gallon.Dave concludes:You gotta haul a lot of containers full of $7 tee shirts to make this profitable.28 feet/gallon!Images from jtashipphoto.dk and Wikipedia.

DIY Hacks for Tiny Bathroom (solving the world's serious issues)

We all know it's a major problem circumnavigating the globe: tiny bathroom living.  My burning question is... How is one supposed to shave their legs in a shower-stall-only bathroom?  Must we sit on the floor with our legs hanging out of the shower just so we can function? Is there no one who can stop this injustice!? What DIY hack can YOU come up with to solve this ever-growing epidemic? (Or what do YOU do to accomplish a streamlined look?)  Save the hairy legs! Thank you.

World's youngest inventor - holds patent for new broom.

A boy of five is thought to be the UK's youngest person to patent an invention after coming up with a labour-saving broom to help his father sweep leaves.Sam Houghton, of Buxton, Derbyshire, was just three when he came up with a double-headed broom to collect large debris and fine dust simultaneously. Sam, who was inspired by animated inventors Wallace and Gromit and Archie the Inventor from TV series Balamory, said: "I saw my Daddy brushing up and made it. There are two brushes because one gets the big bits and one gets the little bits left behind."I don't know if I want to be an inventor when I grow up but this was fun.""I was swapping from one broom to the other and he asked why. When I said it was to pick up the different leaves and twigs it must have got him thinking."He got a large elastic band from the shed and put it over the two brooms, holding them just the right way to use both together. He then called me and announced that had had made up an invention." The broom works with the coarser brush at the front to pick up larger objects and the finer brush at the back.Sam's invention has been taken up by the UK-IPO, which is hoping to use it to encourage other youngsters to come up with inventions through an initiative called "Cracking Ideas".BBC StoryCracking Ideas websiteIntellectual Property Office

The dirty little secrets about switching to LED lights

Some years ago we were told to invest in more energy efficient lights for our homes.Incandescent was using too much power, so CFL's, Compact Flouroscent Lights were the ting to buy.Much higher price than the normal lightbulb but hey we save a lot of money in the long run.No one liked the long warm up time to get full brightness...And even less people actually got the claimed lifespan out of them.Add the recycling costs and hazardous waste created and the costs of using CFL's is actually much higher than standard light bulbs.The only savings were for the power companies.LED lights had a slow start but once mass production started price went downhill fast.What started in the EU was made compulsory in other countries soon after: A ban on incandescent light bulbs.Thee are only a few exceptions left like bulbs for your oven as LED's won't cope with the temps here.So why was the ban necessary?An incandescent light bulb was available for often under a buck, so having some spares at home was no issue at all.Making people switch to LED lights that often cost 20 times the amount of an old standard light is impossible.Biggest incentive of course was the short boom to the local economy as the initial batches were all sold as high quality items.The scam started to evolve when it became clear that even with LED lights the overall savings hugely depends on how you use your lights.As a factor on your electricity bill the lights are usually at the bottom of the list.Things like heaters, airconditioners, fridges, freezers and of course TV's are the main users of electricity in many houses.During the winter times this changes as we need more light but still the impact is not as high as you might think.What did change though was the behaviour.Since we now save so much energy we don't really worry as much if the light is kept on for no good reasons.Again, the main savings are with the electricity providers.I won't deny though that a house with 100 60W incandescent lighs will have some benfit on the electricity when switching to 8 or 10W LED lights....Lifespan...Like so many others I have some stories about incandescent lights...For example the one had in the basement when I was a kid.Often on for several hours, sometimes just for a few seconds to quickly grab something.But it still worked fine when I was an adut and never had to be replaced.Or the house that destroyed lights on a regular base thanks to power surges from the nearby industrial areas.LED light were meant to make the difference here.Put them in and never worry about replacing.10.000 or more hours before the LED's fail...Nice claims but never fully true.10.000 is a bit over a year of constant use.Most people won't just leave the lights on for the entire year.So you would expect that a good LED light will work just fine for at least 5 years, under normal conditions close to 10 maybe.There is several problems with this claim - none of them are explained in the warranty leaflet and nothing was explained by your government when you were forced onto LED light.Electronics even as simple as a resistor come with a limited warranty.Some will remember the disaster when bad capacitors turned thausands of flat screen TV's into flashing lightbulbs.The parts used to make the lights can be a year old already before they are soldered together.Then there is time for shipping, storage, distribution.Sadly not all countries require to print the manufacturing date on the packing or LED light.Means that by the time you put a new LED light bulb into use it might be two years old already.Similar for the claim that the light won't emit heat.Sure the LED light itself is cold but the heatsink the LED's are mounted on is far from it, same for the often underrated electronics inside.In return the electronics suffer from the excessive heat, espcially if mounted in lamps not designed for them.Which makes the entire replacement a scam for most people.It is not uncommon that a LED light fails within a few months.If you are lucky to have kept the invoice for it you might be able to get a new one from your store.Now I replaced 20 lights when I moved in here.Only the first three that failed got replaced, after that the shop claimed I would misuse the warranty.I inspected them and it was not easy to get inside.The switching IC used should have had a heatsink according to the datasheet, without it the circuit board got toasted until the IC finally cracked.Without a sufficient heatsink the IC was only rated for a max of 5W while the light had a LED assembly of 15W...I kept doing these destructive examinations whenever a LED light fails.So far they ALL had sure signs of overheating, either for the switching IC or the tiny transformer.No one really bothers though to keep track of the hours a light was actually used and with that we just keep buying new ones with no worries in the world.Recycling....An incandescent light was never really worth much to begin with, so the final grave was the normal rubbish bin.CFL's required proper disposal due to the hazardous materials in the tubes.A comparison between the amount of sold lights and what ended up in recycling centers reveiled that the ,ajority of them ended in landfill because people tossed them in the normal rubbish.The long term impact of those chemicals on the enviroment will be hidden under fresh grass by then.LED's claimed to be the way out as they were meant to be fully recycleable.What really happend with our collected recycling bins was clear when China stopped taking it.....Means all the still usefull materials in those expensice lights again just go into landfill.A total waste on so many levels.So what is the real cost then?Electricity prices are only going up, so saving Watts wherever possible is a good thing.But ask yourself:How much energy and ressources were required to produce an incandescent light bulb?How much more is required to produce a LED light?We are told to focus on our electricity bill alone without considering the overall costs.Since we already pay the extra of making them we tend to forget what happens once they fail.More waste, more landfill, no recycling of the lights at all.But does it prevent your next blackout when the grid is at max capacity? Nope...Keeping your big airconditioner off for a hot day or two would save more electricity for the year than changing from incandescent lights to LED's ;) Does that mean we get way more efficient airconditioners? Nope...Where in developing countries cheap and highly efficient compressors are used we invented inverter technology ROFLMakes no difference at all on max power to have an inverter.The only real difference is that it runs slower at lower capacity while a normal airconditioner turns the compressor on and off.Forcing the use of highly efficient compressor technologies and replacing our old style systems would have made a real difference on the overall electricity use.We "save" electricity with LED lights and only turn them on if we really need them.Still the 5 or 7kW airconditioner runs all summer long and in the winter it heats the house and uses even more electricity.Makes you wonder, doesn't it? ;)

You can help save a rare frog from extinction!

First off, I realize instructables does not want pure advertising on their site through these forms. The voting is optional and I don't want this to be viewed as advertisement. If nothing else, I want to share with you our story in the project, and hopefully you'll see how awesome this is. We are doing something that no high school has ever achieved before, and I think it's more relevant to the site than some re-posting of a blog article. I hope that you take a few minutes and find out what the Frog Project is all about! Want to support the cause of helping endangered species, education, and advancing biotech in schools? Well, take 5 minutes and vote for our school to convince Khols' to give us 1/2 million $$! Unfortunately the contest is over, but we're going to go for a $250,000 grant for a Pepsi contest in November. If you become a fan of our page (noted below) you'll be updated. Check back in November! https://www.facebook.com/pages/The-AAEC-Frog-Project/128763967175416 ======================================================== Not convinced? Well, here's our story: You can help save a rare frog from extinction, and it is free! Kohls the dept. store is donating $500,000 to the 20 schools with the most creative need for the money. Your vote can help our school win this money, and best of all it costs you nothing! We are working on a project to try and save a rare frog from extinction. And we need the cash. At our small high school of 300 students, we are trying to completely sequence the genome of a rare Arizona frog. We hope to accomplish 2 things from this work. 1) We hope to rescue this frog from extinction. 2) We hope to train a new generation of students in modern biotechnology, and rescue the State of Arizona from last place in quality of education in the United States. The Chiricahua Leopard frog is currently listed as a threatened species. We have been working in conjunction with the Phoenix Zoo and Arizona Game and Fish to develop a genetic test that could aid in conservation efforts. We have already spent a year working on the sequence of the mitochondrial chromosome of this frog. Our school actually owns a DNA sequencer. We have made pioneering efforts in the design of genetic tests for this frog. Our students have presented 5 posters on our work at the International Plant and Animal Genome conference (PAG), quite an achievement for a high school. Our project was recently awarded one of only three heritage grants: http://www.gf.state.az.us/w_c/heritage_projects.shtml By the way, the other two Heritage grants were awarded to Arizona State University and Northern Arizona University. What we really wish to do is completely sequence every chromosome in this frog. This is a very ambitious project. Consider that the human genome project completed in 2003, cost $3 billion dollars and took 13 years. Our leopard frog is estimated to contain twice as much DNA as humans! However, we think that with appropriate funding, and new technology that has recently become available we can accomplish this task in 2 years! We wish to construct what are called “DNA libraries”, collections of broken chromosome fragments of known sizes. These can be sequenced quickly using NEXT generation sequencing technology. The Chinese genomic group BGI has agreed to cover the costs of NEXT generation sequencing, and genome assembly for our project (an estimated $1 million) if our school can come up with the remaining funds needed for the construction of the libraries. We need to purchase about $200,000 in new equipment, and extend our existing lab space. With the completed genome sequence, we would like to have a custom “gene chip” manufactured. This chip will have all the DNA of the frog physically printed on it. The chip allows experiments to be carried out without any harm to any frog. This chip could then be used to aid conservation efforts by the Phoenix Zoo and Arizona Game & Fish. It could allow the exact parentage of every Chiricahua frog that is discovered to be known. Eventually this technology will become the backbone of conservation work on all species, but at this early stage it is not possible for Arizona Game & Fish to raise the funds needed to generate a gene chip before it is too late for the frog. Our school hopes to be the first in history to carry out a genome project. We hope this will serve as a guiding light to other schools, and start a grass-roots movement in the conservation and education world. Help us save our frog! Here is the catch. Vote for us on Facebook, and convince all your friends to do the same (forward this message to them), or unfortunately the frog bites it! Everybody can vote up to 5 times for us. In this way YOU can help make the difference not only for this rare species, but if we can succeed you will help pave the way to help many others. https://apps.facebook.com/KohlsCares/school/32741/aaec-paradise-valley Regards, -Mike Dr. Mike Brown Science Dept.

The risks of DIY carpet cleaning and how save a buck or two....

I am writing this partly because of bed experiences with rental angents/landlords and as a general help.Here in Australia as well as other parts of the world it is common pratise that a real estate agent goes through your rented home multiple times a year to check if you keep it clean and undamaged.In most cases these visits go without any hickup until you move out.At this point agents often try to make your life a misery.Some expect you get the house back to the state it was 10 years ago when you moved - an impossible task.Carpet cleaning is usually done with a rented machine.This mean you pay a deposit for the machine and "rent" is made by the highly overpriced cleaning fluid you have to use with the machine.But more and more people see that a $100 machine from the discounter is a "money saver".So lets start with the main differences between a rented, commercial grade machine and those you find at the discounter to buy.The later comes quite small and in plastic, the commercial one is usually all metal and has huge water and waste tank.And lets be honest here, if a good vacuum cleaner sets you back more than twice what your new floor cleaning machine costs.....For me the real difference is in the sucktion.If you start with 10 liters in a commercail machine then you should expect to get over 8 liters back in the waste tank.The added waste often makes it seem much more though ;)The cheap discounter vesion however often struggles to get half of the water back out of your carpet that it drained into it!This is not only due to the weaker vacuum created but also due to the general design and lack of sealing the area that is sucked up.But during a hot summer week this makes no vital difference as it dries off anyway, or does it?Dryness and contamination....If you wash your clothes than you let them fully dry before you wear them.With a freshly cleaned carpet we often don't have that luxury and if the weather won't play nice you might end with a moist carpet for weeks.A proper wash of the carpet would require that water is actually flowing through the fabric.This is achieved by designing water outlets and sucktion areas to be in close proximity.However, most carpets these days are thin and flimsy, the underlay brings the comfort and often the required insulation from the cold floor.Fun fact: Most quality carpets in the EU come with a rubber or foam like backing which prevents that little spills go through and also leave the carpet basically dry after a cleaning.If the amount of water your machine collects does not get very close to what you filled into the tank then you end with a quite wet carpet and underlay.Cold from underneath and with basically no airflow through it.And if you ever removed an old carpet that was cleaned every few years you do know why you wear a protective suit, gloves and a filter mask on your face....It is simply impossible with a handheld machine to prevent water and contaminants from getting into the foam underlay of US and AU style carpet assemblies.Once fully dry there is little chance for anything to grow, but every time you clean the carpet you add the water required...I had it in two rentals that when I cleaned the carpets with a really good machine that stains from within the underlay came back up into the carpet.A job planned for a day then turned into three days of using heater fans and living in a sauna while washing carpets :(The same is true if you end up with fresh dirt or such on the carpet while it is still moist underneat - it gets worked ino the carpet and becomes even harder to clean.Is a commercial cleaning the better option?Sadly I have to say this highly depends on your agent/landlord and how much time and money you have.In some areas agents simply ignore the law and demand from you that the carpet looks at least as good as when you moved in.And if old stains you did not know about come from the filthy underlay a rented machine can come close to the cost of getting a commercail team in to do the job once you vacated.Either way you get an invoice for the service and a statement about the condition of the carpets before and after the cleaning.These guys come with a big van and before it fires up with water only the vacuum is used.Imagine a monster sized vacuum cleaner head on steroids that connects to an industrial sized evacuation fan in the van.It literally lifts your carpet from the underlay and leaves nothing loose behind.The actual cleaning and sanitation works the same way only with the big difference that the water is sprayed with pressure through the carpet and into the underlay.Final round is done dry and with vacuum only, means the carpets are dry enough to walk on them without getting wet feet.A complete dry state is usually reached within 2 days during the summer unlike rented machines that keep the humidity in your house up and high for about 2 weeks until back to normal.Main benefit of a commercail cleaning is that you won't get any issues with your agent/landlord unless you damaged the carpets or made them impossible to clean - ever dropped an ink jet printer refill kit? ;)If I do it myself with a reasonably good machine or a rented one : Do I have options for the cleaning solution used?Trust me, I had to figure that one out quickly when I moved into my first rental down here.4 bedrooms, entire house with carpet except for the kitchen and wet areas.They appeared reasonably clean at a first look but when I used a UV flashlight at night the story was shocking....In what must have a room for a baby the carpet looked like a psychedlic art impression under the UV light.The living room was not much better.As a result the rented machine ran out of cleaning fluid quickly.Bought 2 bottles that were supposed to be suffient for the house size but if you need several rounds per room.I "finnished" the former baby room and was one bottle down already.Called it a day and in the dark the UV light showed a slithly fades art impression but nowhere clean :(The shop had a heavy duty cleaning solution but I did not consider it with a price twice as high.Instead I wondered what would make my carpet different from my clothes in my washing machine....So I got a canister of Oxy-cleaner - sometimes called nappy soaking powder, or similar.Just make sure you get one that does not foam up too much.I used a bucket to dissolve a good amount of the powder before filling it into the machine - at about 40°C.What ended in the waste tank when using this cheap alternative looked digusting to say the least!With that encouragement I decided to make a new bucket with some added washing powder, just a tablespoon worth or just over.Washing powder for front loader does not foam up much, unlike the stuff for top loader, so choose wisely.That was, all counted, the forth cleaning round for the former baby room but after this the UV light showed a clean carpet that also had nice spring fresh smell thanks to the washing powder.Using the same appraoch of lots of oxy cleaner and a bit of washing machine powder in semi hot water made cleaning the rest of the house a breeze!When going slow with the machine it was like mowing the lawn, it left a clean path behind.Not all carpets might tolerate oxy cleaners though, especially if they are quite colorful, so do a spot check first if you never used the stuff to clean up a little spill of red wine before.And please keep some of the commercial cleaning fluid at hand to give the machine a quick wash through with it, otherwise the shop might ask you if you used non approved cleaning stuff with it ;)Tips for adjustable cleaning machines....Some of the rented machines come with several possible adjustments you can make.In the most basic form you can adjust the amount water used and how strong the machine sucks.Keep the sucktion as high as possible unless you actually want to pre soak the carpet.The amount of water should be adjusted to the type of carpet not to how dirty it is!You want just enough water to soak the carpet without going into the underlay too much.A clear sign of using too much water is if you waste tank is only half full when the water tank is empty.A few of the really good machines let you adjust the distance between the water outlet and sucktion area.In most cases there pre-set to what, from experience is the most commonly type of carpet in the area.Your might be different though...A greater distance means more time for the cleaning solution to do its job.This works especially well for thicker carpets with amount of water turned down to below 50%.For thin carpets a short distance is better as the water does not have to go deep into the fabric.Here you can even increase the water flow for very dirty areas without risking to soak the underlay too much.In either case you should check the machine before taking it home and if adjustable have the options explained to you in the store.Anything for really bad areas?The entrance area is often subject to whatever our shoes collected outside, especially if you have kids or playful dogs.A bit of oil from the road, some sticky residue of something, dust, small gravel and sand....Vacuum out what comes out first, then use a suitable, not too stiff brush if your vacuum cleaner does not have a rotating brush in the head.Use a spray bottle and prepare a solution of warm water with a bit of washing machine powder and a shot glass worth of methylated spirit.Slightly wet the soiled area with the spray bottle without saturating it.Use the brush to agitate the carpet fibres - preferably directional and with even strokes.If they are not wet in the deeper areas spray a bit more.Again: you don't want to soak it you want to wet it.Give it about 20 minutes on a warm day a bit longer if the insede temps are below 25°C.Check with your hand if the area is still wet, the alcohol should speed up the evaporation here.Before it dries up repeat the process and check with a paper towel if it picks up the stains already.If so then run over the area with cleaning machine.Best results are achieved if you manage to get the fibres wet all the way down with the brush and won't let the area fully dry off again after the spraying.How can I speed up the drying time?The only way to speed things up is heat and airflow.If outside humidty is quite high then you will struggle.Even in the summer times the humidity levels over night can get well into or even over the 80% region.Opening doors and windows then to get the carpet dry won't really help you.Best time to clean your carpets is actually at night because by the time you are done the sun is out and the humity levels much lower.On a good day below 30%.This is true even for the winter times.Put a few fans up and make sure the temperatures are well above the 20°C mark.If in doubt you have to turn the heater on.Once the humidity inside is sky high you open up all windows and doors to have an exchange of air.A few minutes suffice here unless there is wind at all.If it is a hot summer day you can of course just let it all open until the sun goes down again.During colder times pay special attention to cold areas, like your toilet, bathroom or in general areas that won't warm up properly.Even if the room was not cleaned the moisture can accumulate here and cause mold and mildew.If in doubt make sure the ENTIRE house is warm enough until your carpets are fully dry again.A humidity sensor or gauge certainly helps, two are better so you can check inside and outside at the same time.

Remembering 9/11

Hi everyone. This, the eve of 9/11, the 6 year anniversary of the terrible incidents that occurred on that September morning. I just want to make sure that the victims are never forgotten, and I take this moment to remember the fallen, and those firefighters, police officers, EMT, who all risked their lives to save those trapped. Thanks for taking the time to remember, and I hope some point tomorrow you share a moment of silence with the world to remember. *silence*

Operation Immortality

Operation Immortality is a project to collect and archive the very best of what humanity is and has accomplished. On October 12, 2008, Richard Garriott, famed video game designer and the first second generation American astronaut, will take digitized DNA and human accomplishments with him to store in outer space when he journeys to the International Space Station.The archive will include information on humanity's greatest achievements, messages from people all over the world, and DNA samples from some of our brightest minds and most accomplished athletes. During the month of September, every human being is invited to come to the OperationImmortality.com website to submit their suggestions for our greatest achievements and leave a message for the cosmos. A lucky few may also be selected to add their DNA to the mix and join Richard Garriott as he rockets out of the atmosphere.With the LHC ready to do its thing, I think this organization has surfaced at the right time, save the earth, before we might all die.To def.LINK

Hotel made from trash

The first hotel made from garbage has opened in Rome. Made by Save the Beach, the hotel used over 26,000 lbs of trash collected from European beaches. Designer H.A. Shult explains “It’s made of garbage because where ever you go on this planet there is garbage. We are living in a time of garbage on the planet which we have only rented.” OK, the hotel isn't entirely made of trash. The structure is prefab so that no one gets killed by a pile of trash falling on them. If you want to see it in person, go and check it out soon as it is not permanent.

French paramilitary forces break the Windows ...

.The French administration is slowly replacing Microsoft's products by open sources solutions.It started few years ago, 2005, with OpenOffice, then with Mozilla.And now, the French Gendarmerie (paramilitary forces) plans to replace Windows XP by Unbuntu Linux.http://afp.google.com/article/ALeqM5iU4Lq7tOR_WVOJLZ3IeRaIH03x6wThere are three reasons behind the move [...]. The first is to diversify suppliers and reduce the force's reliance on one company, the second is to give the Gendarmerie mastery of the operating system and the third is cost [...]The move away from licensed products is saving the gendarmerie about seven million euros (10.3 million dollars) a year for all its PCs.The 70,000 desktops of the French Gendarmerie should be 100% Linux by 2013-2014.This is, again, a proof that Linux solutions became mature enough to compete with Microsoft Windows.Dell now sells computers with Linux instead of Windows.OLPC and EEEPC use Linux.Several administrations around the world are seriously planning to move to Linux and Open-Source.Is this is the beginning of a new era ? How many administrations around the world will abandon Microsoft too ?How long before buying a computer with Linux sounds like a serious option for a majority of consumers ?I wonder if Microsoft really feel worried about that ... =o)

Cheap Source Of Propane?

When I got a new can of propane, for my torch, it was $9. At wally world, it was $4. Then, when I went to get a can of cooking stove propane from the camping department (at wal-mart), I notice that the tank was $3. After getting home, I noticed that the threads were exactly the same, and that the torch head would screw onto the neck of the "camp propane" bottle. So, as anyone would do, I fired it up, and it worked! Of course, it would shut off it you tilted it too far, but what the heck! $3 for a can of propane. But then I thought "Why is this so cheap, and why haven't I heard of this before? Is ther something wrong with this? Will I blow myself up?!?!?! Anyway, I'm all for saving $2, or $6 (depending on where I go), so is this actually a reasonable way of saving money?So what I'm asking:-Is this way safe? I haven't fired it up since, in case it did something bad.-Why is it so cheap to but it that way, and so expensive to buy regular tanks?-Has anyone else done this?If anyone can help, it'd be appreciated.

Expiration date of meds?

Finding a beautiful small oak cabinet, with beveled windows, full with a first aid box, some more first aid stuff, and several antibiotics etc. The first aid stuff is fine! The band aids still stick, etc. The antibiotics, and the fungicide expired during the millennium scare.... But then, people store meds in very different circumstances. The warnings are of course based on legal possibilities, like storage in a leaking cabinet on the south section of the mobile home in South Florida of a hyper allergenic patient..., generally not met in most circumstances! Of course many folks will say: DON'T USE IT!! VERY DANGEROUS, ETC.... But I'm sceptical...  Of course big pharma would love me to take it to hazardous waste tomorrow. OK, I don't need these meds.  But suppose someone very poor, like many of my friends in 3rd world countries, got a bad cut, etc. Over there, you have to pay upfront to see a doc, and pay again to get (very common) antibiotics. They phone me. My question: generally speaking, what is the value of expired meds... Would there be a danger, would significant toxic by products be generated, or is the issue mostly a gradual breakdown of the active compound... Which would mean, double dose... Almost everyone has unused meds in their cabinet. This question is very important and the proper answers could result in saving many lives!

Timemachine in Google Earth - Concept Extention for Google Earth

Google Earth History After the Google Earth Software was published on the Internet and became a striking success, I noticed that this software made many basic features available, which were necessary for an idea I have carried around with me for a couple of years. Actually, the idea is connected to a question that many of us have asked ourselves: You are walking on 5th Avenue in New York and wondering how this street looked 20, 50 or 100 years ago. Of course you can look up photos in relevant books or magazines and obtain a certain impression of how life was at a certain point in time in this place. But wouldn’t it be great to be able to transform this impression and create a detailed picture; to be able to literally see more and truly visualize your impression? In addition to the one or two photos which can be found in old magazines or in history books, there must be other historical documentation, which can assist in creating the picture. Surely, you can look at movie documentation, but mostly the specific place that you are interested in, is only briefly shown – or not shown at all. So let us stick with the example of 5th Avenue, New York. A place which has existed for more almost 100 years in its current form; which means something to almost every person in the western world; and which has been visited by a vast number of people at least once. As tourists like to do, they photograph the places they visit to show family and friends, where they have been. It is safe to assume that 5th Avenue is one of the places on Earth, which is most incessantly photographed by a large number of people. What a pity that all these photos are brought back to their owners’ home countries, and thus spread all over the world. The final resting place of these photos is mostly a photo album, a dusty box in the attic, or - in this digital age – a hard disk or a CD-Rom. The sum of all these photos of 5th Avenue would probably form a breathtaking historical view of this street: millions of pictures documenting all small and large changes throughout decades, pictures of well-known people visiting the avenue, events which happened here, the rise and the deterioration of different buildings. This collection of documents resembles traveling back in time in a way, that nobody has ever done before. If the owners of all photos would run their pictures through a scanner or make already digitalized photos available to the general public, you would quickly obtain an unusual diversity of photo documents. Especially, you would gain a multitude of different pictures of well-known places like the implied 5th Avenue. Once more we’ll look at an example: assuming I have a color photo from September 1994 taken on the corner of 5th Avenue and 23rd Street in New York City on which you can see e.g. the Empire State Building. I scan the photo into my computer and use the appropriate import function from Google Earth. Thus, the scan of my photograph is saved on a Google server. With the 3-D view of my Google Earth program I can now head for the corner of 5th Avenue and 23rd Street. On the exact location, where I took my picture in the real world in 1994, I now save the photo in the program’s virtual space. If many other Google Earth users would do the same thing with their photos, we would slowly have a collection of pictures from 5th Avenue. All other users now have the possibility of viewing all saved photos. So, if another user saves a photo of 5th Avenue and 28th Street, all I will have to do is to virtually move five streets north and position myself behind the digitally stored picture in order to view it. Of course, we would soon have chaotic conditions if enough people upload their pictures of 5th Avenue to the Google server: One has a photo from December 1980, another person a photo from June 1982, the third a very recent photo from 2006. All these photos will be saved geographically correct in the Google Earth program, but content-wise they will not fit together at all in such a chronologically un-sorted manner. Therefore, the program Google Earth would have to contain a new function: the depiction of the fourth dimension, time. In short, before you save a picture from June 1971 in the correct virtual place in Google Earth, you will also have to set the correct time, i.e. June 1971. In reverse, for the viewer this means that he will have to select from which time in history, he wants to see photos of the chosen 3-D surroundings, before he views the pictures in the Google Earth 3-D world. So, what is it all for? Just as Wikipedia to this day has proven very impressively, that the accumulation of individual persons’ knowledge on the Internet in sum constitutes a high value of total knowledge, so this collection would form a library of historical documents. Again we will remain with the 5th Avenue example: with a sufficiently large collection of photos the viewer has the option of looking at the street from different perspectives AND from different points in time, which may even be many years apart. History has probably never bee so easy to observe. In the end maybe he sees himself taking his photo in September 1994 while somebody other shot a photo with me in the picture. Strange, isn´t it?

Laser cutter software issue

I use a laser cutter that runs on LaserCut 5.3 To create my files, I draw in Inkscape, save as a DXF file, then import that into Lasercut5.3 Unfortunately, importing into LaserCut5.3 creates artifacts in my files - polygons are created where none were before, and lines are invisibly doubled up, meaning that the laser cuts some lines twice, which wastes time, energy, and can spoil a project if a line goes too deep. Two typical examples are below. In an ideal world, the "e" would come out as two continuous lines (inside & outside).  Intead, it comes out as three lines, and the straight parts of the lines are "doubled over" - it cuts twice. Where two or more straight lines are contiguous, like the "k", the sections gain extra lines that break it up into smaller polygons. (I have shown the extra lines in red). Both cases are fixable, on a file-by-file basis, but, in the clunky LaserCut5.3, the fix can take longer than the original design. Has anybody else experienced this issue, and how did you fix it?

Geek Magnum Opus completed!

It is complete! My geek magnum opus, my meisterwerk, my... big long project that I conceived of several years ago while reading hackaday and thinking "I wish I were l33t enough to have something posted on hackaday"... it is finally complete. I was going to save the "big reveal" for completing an Instructable on it, but hell.. I'm really excited about it and so I'm going to give you a sneak preview. I have created a real world implementation of the Hitchhiker's Guide to the Galaxy. It's about as big as four mobile phones put together or a very small paperback book, weighs about 400 grams (under a pound for our friends in Liberia), runs on regular batteries, doesn't rely on having an internet connection- it's just the sum total of humanity's knowledge (ok that's a slight exaggeration), in your pocket. I'm annoyed that I missed the deadline for the pocket-sized competition by two weeks, because I think this one could have been a winner. Never mind. I still have my geek sense of achievement :) Watch out for an Instructable coming soon, where all will be revealed...

Dead external hard drive?

I've been searching the internet for answers for the last couple of hours, but no solutions have helped me so far. The more I think about it, the more I'm sure that I have to either take it to an expert for data recovery, or if that isn't possible I'll have to accept the fact that the files are gone. So earlier today I was frapsing some PS4 content with the help of a Roxio video capture (PS4 signal blocked so I used Fraps to get around that). I've been saving the files on my C: drive, but since fraps files tend to get quite big, I changed the save destination to my external hard drive (Buffalo). Immediately after I ended the recording, my computer froze and I had to force shutdown. Upon restart, it started to repair damage to the disc (translated from Finnish), and once it was ready, it then proceeded to the system recovery menu. After at least 2 hours of trying all other options, I ended up choosing the option that resets my computer. Well that really wasn't the end of the world, since the most important files are on my Buffalo hard drive, but after the reset was complete, I couldn't access my external hard drive. I tried everything in Disk Management, at least what was suggested in similar issues, but nothing really changed anything. I can see my external hard drive in the Disk Management, but can't access it. When I try to initialize the disk, an error pops up that says: "Data error (cyclic redundancy check)", and it just shows that the disc is not initialized, and that it is unallocated. Is there any other option than either taking it to an expert for data recovery, or is that too late now? Thanks in advance.

I want to Make a HUGE "3D printed" sculpture of a PACHAMAMA DRAGON with a drop fountain in it's eyes and a sensor smoke machine and more.(HOW CAN I DO IT?)

I have close to 0 pratical skill in arduino and raspberry,Questions: What`s the easiest way to make a sensor so when people are close to the head it starts crying in drops (maybe gold like liquid or glow in the dark liquid or red liquid)What`s the easiest way to make a sensor connected to a smoke machine? Where can I buy a drop water fountain?MORE IMPORTANT:What are the name of the professionals who can help me tech the dragon? does anyone knows cool things I could add to the dragon to animate it somehow?Maybe an entrance to put coins and money and some lights would light the whole dragon from inside, maybe a foam machine on the mouth or a flametrower.Is there any light that with a special bulb or opaque acrylic that stays smooth like a car`s neon and not localized when seeing it directly? how could i light the dragon in an epic way , having in account that the dragon has a rooted intricate body and we can put lights inside? maybe i can put the lights. Who is the professional who can put wholes for the lighting system and it-s wiring on the 3d model before we print it?______________________________________________________________________________________________I Will reproduce this model of this dragon (https://www.turbosquid.com/3d-models/3d-rigging-motion-paths-model-1150078) and MIRA ARTS RESHAPED SO IT LOOKS LIKE IT'S BODY IT'S MADE WITH THE ROOTS OF AMAZON,like this one(https://www.kickstarter.com/projects/mira-arts/forest-dragon) , rigged again in an epic way to fit inside a particular room along the walls, with a 2m wide head and an asian dragon body so it can spiral and swirl and curve around the room, like the walls are water, maybe even go behond walls outside and trough windows.it will have simple sensors so when you're close to the head it activates smoke machines there, maybe an "Ha" soundwith the help of architects, we will assemble the creature on site.I will reproduce it with around 500$ of cardboard sheets laser etched in topographical layers (PRICE) with the help of 123dmake (check it out), maybe then plastered and sanded down.like this tutorial until step 4. (https://www.instructables.com/id/Fine-Art-from-Cardboard/)with this system we can 3D print the dragon and anything imaginable at a Giant Epic scale!I'm going to kickstart this project ______________________________________________________________________________ _______________________________________ Fluff to save the World: I will name the Artpiece with a long name "Niu Pachamama Dragon :Bolsonaro, me muda o nome da Amazonia para Pachamama para ter um lugar mais visível no Google para salvarmos a Pachamama, vai!" or in english: "Mr.Bolsonaro (Brazil's President), can you change the name of Amazon Forest to just Pachamama so it can have better ,non confusing google searches and we can finally save it from ilegal deforestation?"Amazon has been unconsciously hidden UNDER Amazon Company IN WEB SEARCH ENGINES for too long,it doesn't have any clicks on search engines, it needs a legit different name for it's core to survive on aND PUMP the PLANET TROUGH THE internet.This way the company and the forest can coexist in different non intersecting google "cupboards" without any confusion for kids and adults alike.If the president changes the name OF aMAZON TO PACHAMAMA TROUGH THIS DRAGON SPLASH, we can bring tons of attention to Pachamama, the New Amazon AND POTENTIALY SAVE THE WORLD!.eCK!For 2020 WE CAN EVEN BE CELEBRATING 3SMAS INSTEAD OF CHRISTAMAS, WHERE INSTEAD OF TORNING DOWN A PINE TREE EACH FAMILY PLANTS 10 PLANTS!MERRY 3SMAS EVERYBODY, TREES MUST SURVIVE!THEI'RE ALIVE!The dragon has become a global symbol for epicness, Myth, entertainment fantasy monster,But the Virgin Amazonian Augmented Dragon or new Pachamaman Dragon CAN BECOME The transcendental symbol of good hope FOR PACHAMAMA,meaning, a guide to Brazilian politicians to "Get a legit Google cupboard for amazon RIGHT NOW!",protector of treasure with the TREASURE representing the Forests, specially the amazon, and hope that we can still save and act for all the forests of the world!a nEW PACHAMAMAit represents the fertility of the amazon, also IT'S deforestation,it's brutality, and future connection with mankind!iMAGINE THAT! and the dragon has an augmented DBZ scouter on the eye that represents the Good side of transcendental connection between human and machine(equals dragon, a symbol of leadership)(https://i.ytimg.com/vi/xiKcimY1iEc/maxresdefault.jpg) It represents the new transcendental connection with technology, you can have a google glass augmented "game" where you become an instant druid in the rainforest, with the camera reckognizing everyplant and medicine that you wish, and dosages for it, and where to get the next one for the recipes AND HOW TO PREPARE THEM.

Homemade electric nail file

Hey there to all you wonderful people! I have an odd proposal / suggestion / idea... I was wondering if anyone had ever considered this as an Instructables project by any (small) chance? Don't laugh TOO much, this is not something that would be considered a run-of-the-mill every-day kind of DIY by any means... Here's my ish: I'm not incredibly fantastic when it comes to personal grooming, doing the basics as quickly as possible so as to waste as little time getting ready for the day. However, me tooties are a point of some concern due to an out-of-the-ordinary dermal condition. As a result of this, I have to take special attention to moisturizing feet and toenail filing. Also, I suffered an accident when I was much younger that caused the nails on the big toe to grow skew. Long story short I've now been sitting on the floor for 40 minutes with a manual file and, while my one's and two's a looking smashing, I thought there MUST be a way of making my own electric nail file. I thought to try and convert a screwdriver bit for my electric screwdriver into a spherical file which I'm sure would literally save me HOURS and will do my knees a world of good - I've found myself kneeling in 1 position for a lot longer than nature intended. I am NOT the shining Instructables Star in the making by ANY stretch of the imagination but I do have some interesting theories about time travel (not really applicable here, but I wanted to try and sound less daaa - cos this isn't a 'Change The World' kinda project) In any event, I thought maybe someone who has a grasp of my concept and an understanding of how things worked may have a thought on how to accomplish this? Baring in mind that where I live, things like electric nail files are luxuries available only to a specific  social group & not an option for the general norm pavements specials such as I... I'm so interested to see if anyone could give me some help. You'd LITERALLY be saving my life (or at least adding about 10 - 15 years to it where I don't have to spend crouched over a small chair for a quarter of my day every 5 or 6 days) Stopped giggling yet? :) Tx guys, it's a dumb thing to ask, but this dumb thing has the potential to SIGNIFICANTLY change my life in a very practical way. Kind Regards and Loads of thanks! ps It ses to add images, but I think just for the sake of global sanity I'll refrain until I've found a working solution (or a pic of someone else's feet) :) Much love t'ya!

A Supercar Made Entriely of Wood

Joe Harmon, a product designer, wanted to show that wood isn't a past's material and that it can be used for high precision engineering. So with a couple of friends and a dog, he's buidling a supercar made entirely of wood (oubvisoulsy not the engine). They even made some of the tools they're using, like a loom to weave the wooden composite!" We aren't really all about mission statements around here; too often, they are phoney and superfluous. That said, here is ours. We are building a high-performance, mid-engined supercar from wood composites as a graduate project at North Carolina State University. Wood will be used whereever possible, including the chassis, body, and large percentages of the suspension components and wheels. The car has a target weight of 2500lbs and a power goal of over 600 horsepower. We aren't trying to sell anything; we aren't trying to save the world, and we aren't advocating that everyone should drive a wooden car. This project is a scholastic endeavour in which are simply trying to explore materials, learn, teach, share ideas, and stimulate creativity. This section details who we are and what we are doing. We hope you enjoy checking out what we are working on. "Joe Harmon DesignFlickr Photostream

Could one insulate their attic and/or walls with those stupid plastic grocery bags...safely and effectively, that is?

I have switched to some awesome reusable bags I bought at Office Depot that have a little bag that clips onto your purse or belt-loop. But I joke to the grocery clerks (when they look at me funny when I hand them the bags and say no more plastic) that if I bring home 1 more plastic bag I'm going to drill a hole in my wall and start stuffing them in for insulation...my question is...Could I Do That? Safely first of all, but also effectively? This would be a HUGE find if it is...We could hit a planetary Royal Flush...Reducing our energy consumption by cheaply over-insulating our homes (an option that would make it possible for poor folk to take advantage too) AND getting those pesky bags off our streets, out of our oceans thereby reducing pollution and halting the devastating effects they have had on the sea life, AND reduce the space they take up in our landfills, PLUS with this as an alternative to having to turning them in, the current backlog of "recycled" bags piling up because this economic down slide reduces the amount of these goods that China is importing to turn into future landfill occupants. So can it be done?

Any PIC Experts out there?

Can somebody help? I have a few PIC16F628, ISD2532 sound chips and 4-digit seven segment LED displays with MM5450 chips from some old laser-gaming boards that I’d like to do something with but have got completely baffled by the data sheets and the complications of PIC programming. Basically, what I’d like to do is create a ‘dummy bomb’ as a present for my local gaming field along the lines of:- • Have a hex keypad enter an ‘unlock code’. Display and save that code • Use the hex keypad to input the time to start counting down from (Minutes & Seconds). Display and lock in that time • Have a button start to ‘arm’ the bomb and start decrementing the time and display it • When the timer reaches 00.00 then ‘fire’ the sound effect in the MM5450 and have an output go low for triggering something else • The device can be ‘defused’ by entering the correct code (equal to that previously stored) or by cutting the ‘correct’ wire – other wires triggering the device. It would seem to me that the ‘wire cutting’ scenario could be accomplished by using tied inputs – one changing state defuses, the others trigger the device. In an ideal world, the device would have 2 operating modes – timer and non-timer, the non-timer mode allowing for the device to be triggered by trip-wire, breaking an IR beam, a ‘hit’ from a gaming gun, etc. In a perfect world, it could also send a 56Khz IR data stream to ‘kill’ all the gaming guns within range but I don’t know the coding for that data stream and it may be in the realms of fantasy anyway… I don’t have a PIC programmer yet but they don’t seem difficult to build or hard to find – only having a laptop means USB though and that does limit things… I can do all the wiring and packaging but is there somebody who could help me out with the programming and/or general advice? Thanks Duncan

Escape from Berkeley

DARPA had a Grand Challenge. . . the rednecks a Cannonball Run. . . and the hippies a bunch of WVO buses broken down on the side of the road. Now, NASA scientists and junkyard fabricators go head-to-head in a no holds barred battle of engineering prowess and creative excess. Hanging somewhat in the balance, are bragging rights for saving the world. That, and a grand prize of $5,000.Escape From Berkeley is a road rally taking place this October, from Berkeley CA to Las Vegas NV, which is open only to alternatively fueled vehicles. It's being put on by The Shipyard, "A collaborative build space for Art and Energy". There are eight vehicles already registered, most of which are using some variation of gasification of scrap biomass as their fuel. It is open to any vehicle meeting the alt fuel requirement that can get to Berkeley by October.This weekend they are having an Open Shop Weekend wherein registrants can work on their vehicles, also potential registrants with potential vehicles, also various interested parties and hangers-on. If the idea of getting a car to go from Berkeley to Vegas using nothing but coffee grounds appeals to you, this is your kind of road rally!Images are of "Kristie's Flyer", a steam-powered runabout associated with the Neverwas Haul, and "Hooker Cooker" which I know nothing about but had an interesting picture. More info is available at the Escape From Berkeley site on the Vehicles page.

Brainstorming - Teamspeak PTT Bluetooth Device

Gurus of the Tech World, First off, I'm browsed through a lot of great idea and I've got to say, you all are geniuses.  Hopefully, someone can help steer me in the right direction.  I have made a few Windows Phone apps, made a few HTML websites and some networking fundamentals, but I've never really made a device... much less soldered a board. With that said, I want my first project to be a Bluetooth Push-to-Talk (PTT) button for Teamspeak.  I have a Bluetooth headset with a microphone for Teamspeak (VOIP PC Application) so I can hear people speaking while being away from the computer but I do not have a way to communicate back using the Push-to-Talk method. So, what I want to do is make a small Bluetooth device, maybe powered by a 9V, with a single PTT button, and maybe an ON/OFF switch to save power.  My thought is to program it so that it send a keystroke to my computer for the duration that the PTT button is pressed (CTRL would be ideal).  This is something that I want to make, using as much of my brain as possible and the least amount of prefabricated merchandise ("omg, just buy a bluetooth dongle and plug it into a button. ta-da"). I'm sure that this is something you guru's can do blindfolded, but, please, point me in the right direction... and use baby words. Thanks! Stryker2k2 (@stryker2k2)

What is the next game in the Compilation of Final Fantasy VII?

After the success of Final Fantasy VII, an entire series about it was made. Starting with the prequel game Before Crisis, a game about the Turks, after that was a movie set 2 years after the original FFVII called Advent Children, next was a sequel to FFVII called Dirge of Cerberus, which is set 3 years after the original game, it is about Vincent Valentine a secret character from FFVII. After that was the prequel game Crisis Core which is about the Zack Fair who weilded the Buster Sword before Cloud. The creator said that the Compilation will continue until the 20th anniversary of FFVII, so what do you think it will be about. WARNING SPOILERS!!   I think it will be a game about Sephiroth's past and his time in SOLDIER leading up to the Nibleheim incident. Or mabey a a game set after dirge of cerberus because in the secret ending of that game Genesis Raphsodos, the villian of Crisis Core picks up the defeated Weiss and says they have much work to do but the creator said that Genesis is trying to save the world so mabey a game about him. Another fun game would be another 3rd person shooter about Cloud Strife's time as a Shinra infantryman leading up to when he met Zack. Tell me what you think will happen next!

How can an Arduino be used to show open/closed trading times of stock exchanges within a Time zone clock display?

I'm making a clock display for my wall, with 3 clocks showing the times in NYC, London & Hong Kong. I want to use them partially to monitor each cities' stock exchange (opening & closing trading hours). Is there a way to integrate an Arduino to control two LEDs (1 green 1 red) and turn green for trading hours and Red for closed in each clock? 1 Arduino per clock I assuming.  I have experience with Ardunios and this project will include a Arduino (obviously) breadboard with jumper leads, xbees, LEDs, 9v (a set of all these things per clock I'm guessing), but this is beyond my knowledge base, and wanted to seek the help of those who know more. lf battery life is going to be an issue (always illuminating an LED), 1 green light for open trading could also be used to save electricity.  How can I create an trading hours database, reference GMT time and a script which uses all this data to make a true/false value for an LED to show the current open/closed status? In short how can I bring the project to life? Is it even possible? I would be very grateful for any help. Thanks.

A glimpse into nuclear disaster.

A team of engineers has used an endoscope to carry out the first visual inspection of Windscale 1 nuclear reactor for more than 50 years. In October 1957, it was the scene of what was the world's worst nuclear accident when it caught fire and released radioactive material into the atmosphere.Just over 50 years ago, British nuclear scientists, under political pressure from a succession of Prime Ministers, had been pushing the reactor to and beyond operating limits in an attempt to develop the UK's own independent H-bomb and achieve an "alliance of equals" with the US.When the fire occurred, the scientists were faced with a choice: let it burn, and contaminate Europe, or dump water on it, and potentially die in a nuclear explosion. They chose the latter, risking their own lives to save people who didn't even know there was a problem.That sounds heroic, but the official report into the incident blamed the scientists for the accident, rather than let the US find out about the H-bomb programme just in the days before signing a treaty to share their existing knowledge with the UK.Windscale (now known as Sellafield - the name was changed after the accident) is now in the long process of closing down. Along with jobs, buildings that marked the dawn of the nuclear age are being slowly demolished and moved ... somewhere else. They don't know where, yet, but it will probably end up remaining on site in deep holes (down in the porous sandstone that carries the local water-table).The original piles were shut down immediately after the accident, and the site's AGR reactor was closed down 27 years ago, but it is only recently that they figured out what to do with them, and they are now being decommissioned as a "UK's demonstration project (meaning; "we've never done this before, we'll work out the bugs in remote Cumbria before we try it on a reactor near a city").As part of the decommissioning work, they now need to see what is left in the ashes of the world's second reactor disaster before working out what to do next.I don't know about you, but I'm not convinced that a paper boilersuit would be enough protection. Maybe that's why the chap on the right looks like he's crossing himself...

Idle daydreaming about 3d printing

I love the idea of 3d printing, and would love to make it a hobby at home.  I can afford the machinery, I have the space, but I don't have the time to gain the required expertise. I have a laser cutter, but most of what I make is effectively two dimensional - design takes a while, but not an age.  For more complex shapes, there are online generators for boxes and gears, which I can use as starting points to my finished objects. What I would *like* to see is a combination of existing technologies - image and motion-sensing devices with virtual and augmented reality - to allow a kind of digital sculpting. My hands would be monitored by cameras (say, a Kinect), and in my Google Cardboard I'd be watching a "solid" object being sculpted. Like 2d drawing software, there would be a library of shape-drawing tools - discs, cuboids, spheres, rods and planes - as well as the ability to manipulate a lump of virtual clay, or draw surfaces and edges in space and have the software fill them in. I would then be able to save those sculptures and 3d print them, or slice them up, or reduce them to to surfaces to laser cut. Since I'm dreaming, I'd like to be able to take hold of a curved surface in my model, and flatten it out to be cut, with the computer automatically drawing in one of a selection of living-hinge cuts to make it possible to curve the surface in the real world. Just putting the idea out there.  Maybe somebody with the skills will pick it up and head over to Kickstarter...
