Under Attack!? Answered

I was watching the news and all over, the weather is going overboard.  Just saw China has some extreme snow. Even us down here are having more pronounced weather than before.  Hotter here now in summer and the rains are going absolutely crazy further up country.  Also went through extreme winds and rain awhile ago, much stronger than I can ever remember. Is this the climate change showing itself?

Creaking under the Strain?

I've been getting periods of 503 errors (service unavailable) from Instructables recently. Are the servers creaking under the strain of all these weighty PRO members, or is the Instructables Robot hard at it mucking out the caches as he tweaks the privileges?

Under Desk Lighting

I'm getting ready to purchase a desk with frosted glass surfaces (http://www.officedepot.com/a/products/578355/Realspace-Alluna-Collection-Milk-Glass-L/) and want to add lights of some sort under one of the surfaces so that I can use part of the desk as a lightbox for sorting negatives and slides.  I'm guessing that a fluorescent fixture of some sort would be best, but I need ideas on mounting (there are rails along the front and back of the surfaces that have around a quarter-inch clearance from the rubber offsets that hold the glass), what kind of light to get and how to wire it.  Anyone have any ideas?

Under Ground Fort

I'd like to build an under ground fort, it must be water proof. I want to have a stove in it if possible, i will have big ventilation so as not to have a build up of carbon monoxide. I have access to a wide rang of tools, I live on a farm so space isn't a problem. I did find a plan in a magazine from 1929, its rather vague and i would like more help. I can take as long on it as it long as it takes to build it right, so time isn't a problem. I don't know if i should pack the wall with stones or planks, Ideas? I want to have a good idea of how to do it before I start. It shouldn't be to expensive but that isn't really a factor. People are saying that I shouldn't build an underground fort because of the danger of it. If i didn't make a fire place in it would it be better? How about I put a trapdoor above the fire place, that way i could open it when i used the fire (Update)

'Leather' channel under 'Workshop'?

I believe a 'Leather' channel under the 'Workshop' category would be a good idea. I say this, because I'm often looking for leather-related instructables, and I suspect that many other people are, too. Leatherworking is as much its own specialized skill as sewing, woodworking, electronics, etc. Maybe you could even inaugurate the grand opening with a contest. :)

BJT under saturation condition??

Under saturation condition base current is very large that voltage across Base-emitter junction of  silicon based BJT is more than 0.7 volt. In this condition the voltage at collector (Vc) is 0.2 volt. By kirchoff's voltage law Vc=Vce( imagine emitter is directly grounded) Vce =Vcb+Vbe. If Vbe>0.7volt how Vce=0.2volt? As Vce includes Vbe, it must also be more than 0.7 volt. But it is 0.2 volt wich is less that 0.7 volt. How?

Laser Engraving Under Glass.

Just put a video on Youtube about Laser Engraving under glass.A lot of people have made their own Laser Engravers using one method or another.I did the same using old DVD drive mechanism's a couple of Easydrivers an Arduino UNO and a 2 Watt Laser Diode and a Constant Current Laser Driver with TTL / PWM.Arduino has GRBL 1.1f loaded on to it and I use LaserGRBL (free program) to do the image settings, generate the GCode and burn the image.It's a good little machine, although the workpiece size is only 39mm x 39mm max.Eventually I'll build a bigger machine, but for now it does what I want it to do.Recently I removed the fan that blows the smoke away because it was whining a bit and getting on my nerves.So instead I tried using a piece of glass cut from an old flatbed scanner, on top of the workpiece.Seems to be good quality clear glass, I suppose it had to be if it was in a scanner.This stops the Laser from producing smoke and also soot.It does however produce a sticky residue on the back of the glass, but that can be cleaned off in soapy water.I was quite surprised at the results.Laser Engraving Under Glass.

Category changes under the hood

Just pushed out another release of the site.  The big news here is that we have enough content now that it was time to reorganize it. The new system isn't live yet but before we can do that, we have to get the current Instructables sorted... Christy wrote a post about it here which explains the whole thing in detail. I invite you to read and comment on it.  Additionally there are a couple administrative changes to make things easier for the site admins, and a bugfix or two... and I just noticed we broke the RSS feeds AGAIN!  Will fix that first thing in the morning, boy do I feel silly doing that twice in a row. Please let us know if you see any problems by filing a bug! Update: RSS feeds fixed (all the ones I saw, anyway; let us know if yours is still broken).  Also authors' ability to update their categories & channels.

Getting Started 1.1 What is Instructables?In a sentence: Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. A bit more in depth: It was created by Eric Wilhelm, a mechanical engineer, and launched in August 2005. Instructables is dedicated to step-by-step collaboration among members to build a variety of projects. Users post instructions to their projects, usually accompanied by visual aids, and then interact through comment sections below each Instructable step as well in topic forumsWhile a member of the Media Lab at MIT, Wilhelm co-founded Squid Labs, an engineering and technology company specializing in design and consulting. Instructables started as an internal Squid Labs project, which Wilhelm has since spun out as an independent company and acts as CEO.The original content focused mostly on such projects as building electronic or mechanical devices to solve common problems around the home. The scope of the project has expanded to include a larger array of categories, including arts and crafts, food, home, life, offbeat (first known as "not liable") and recently knex, transportation and tech. The site allows uploading of photos, diagrams, video and animation to help explain complex terminology and mechanisms in clear and understandable termsRead more about the history...Also, Read our About to see who works here1.2 How does the Site make money? Is it profitable?The site is mainly supported by ads, which you see in the sidebars and sometimes at the top of the page. Here is the full explanationIs Instructables profitable? - Almost. According to ewilhelm , the site generates enough money, that it usually covers its running costs, but not quite enough yet to be constantly profitable. 1.3 What is the Instructables Robot?The Instructables Robot is Instructable's mascot. His main function is to greet new members and alert members when they receive comments or messages. The robot is friendly and welcoming. You can easily find him around Instructables.You can tell the robot to alert you if you receive a comment in your personal settings. Likewise, you can tell him to stop doing so anytime at your personal settings.Nobody knows how exactly the robot came to Instructables.....time may tell......1.4 How can I get started here?You probably want to upload an image to your profile. You can do that here , as well as change some of your other account settings, like making View all Steps in one page your default.After that, check out How to make a great Instructable , The Guided Tour of Instructables, and the Help Group if you have any questions.1.5 Who can Help me get started here? ANYONE! all users are helpful. If you are confused, or have a question, don't be afraid to ask in the forum of a member of the community. Our members are happy to help newcomers get comfortable. You are more likely to get lots of help through an open thread, but you can ask questions privately (say, for a project in development) through the "Private Message" system.Have a look at other FAQs in the FAQ Section1.6 What does DIY mean?DIY means Do-It-Yourself. It means that instead of buying expensive stuff, make it yourself and save some money. The main idea of Instructables is to make things and share them with others. You will be surprised about how much money you could save if you do things yourself, and we are here to help you.1.7 What can I write an Instructable about?Bearing in mind our family nature, anything at all. If you're passionate about it, and want to tell others how you do it, then write an Instructable. If you're looking for inspiration, check out the Burning Questions to get you started. When you're a bit more familiarized try entering our Contests1.8 What's the difference between an Instructable and a slideshow?In an Instructable, you show detailed step-by step details on how to make or do something. A slideshow is used when you do not have enough documentation or material for a full Instructable. In a slideshow, you can show off projects or things that you have made. If you want to show something, but its not enough to fill an instructable, you can show pictures of it in a slideshow and write a short summary of the project.1.9 What is a video on Instructables? If you do not want to write a full instructable, but you want to present something that can't be fit into a slideshow, you can embed a video as an individual section.1.10 How can I unpublish my Instructable?It's a slightly-roundabout route, but if you click the edit function, then the publish, and unpublish options appears lower down the screen.2. The Community2.1 How can I make text effects like bold, italic , small text and upper small text?Read this helpful Section by Instructables member NachoMahma2.2 Why doesn't my Instructable show up on the search page when I type the name? Instructables are reviewed by the Robot and his human minions before being added to the public pages. Be patient, it may not have gone through the filter yet. Is your instructable lacking images? Sometimes instructables without images fail to go through the filter.On weekends and Holidays, where there is an influx of people posting projects, it may take longer than normal for it to show up in the Most Recents. If there is a problem with your work, someone on staff will PM you.Your instructable may have been caught by the spam filter. If it has, contact anyone in the Instructable team, and they will check it out for you. Just Be Patient.2.3 What kind of material is considered offensive? What kind of material should be avoided?Pornography - Any and all pornographic material is considered offensive. Posting images or links that include pornography is strictly prohibited. This is a family friendly site, children often browse this site.Language - If you wouldn't show it or say it to your headteacher at school, don't show or say it here.Insults and flaming - We have a "be nice" policy here. Please be positive and constructive with your comments or risk being banned from our site.Spam - Spamming, misleading links and site advertising on the forums, orangeboards, instructables, and Private Messaging are strictly prohibited. However, offers and advertising are allowed in the For Sale Section2.4 Why am I asked to give a number when I send a Private message to someone?This is called a Captcha. A captcha is when you are asked a number or word that appears as an image or sound. The purpose of this is to stop automated spam robots from spamming our Community.2.5 Can I ask for homework help on the forums?Of course! Our community is more than happy to help any way possible! Be sure to post in in the right category, because you wont get much science help in our craft section!2.6 How can I improve the community?You can help our community in many different ways:Be positive and constructive in your comments. We are a friendly and welcoming community, feel free to comment and incorporate yourself into forum topics and discussions. Our members are happy to help and guide newcomers in any way they can.Report offensive material. If you spot material that might be considered offensive or SPAM, click the "flag" button next to the comment or instructable. The Staff will review and take action if necessary.2.7 I've spotted an offensive ad! What can I do?If you spot an ad that qualifies as offensive, right click (not left click!) on it and choose properties. In Firefox, you can right-click and select "Copy Link Location". Copy the URL and report it to a staff member so they can take immediate action. If possible, it is also good to take snapshots of the page (On your keyboard, press Prt Scrn and paste it on MS paint or another image editing program) then present it to a staff member.2.8 Can I post Instructables in other languages?Of Course! We would be extremely happy to add instructables with languages other than english. If you need help with some words or terms, feel free to ask around on our community! Proper grammar and spelling are compulsory in any language. We have a lot of users who are fluent in many languages including Spanish, German and French.3. Other Instructables Features3.1 How do contests work?There is no complete answer to that question, as different contests have different rules. Usually, a contest follows these steps:1) A staff member usually announces that a new contest is coming, and what the theme will be, so members will start getting ideas2) The Contest is announced in the front page3) A staff member will post an instructable on how to enter the contest, and will show full details about it.4) The Contest is then opened for entries.5) After a specific time, the entry deadline closes and the winners are chosen either by the staff of by community votes (Depends on the contests specific rules) and are announced.There are two kinds of contests:- Regular contests are the ones that last a month. These contests also set the month's specific theme. These contests are usually sponsored by a company that is related to the theme. For this reason, prizes almost always come from the companies themselves. Regular contest feature more expensive prizes.- Speed contests are those that only last a predefined time. They are called speed contests, because users have to submit their entries before a close deadline. Since they last such a short time, there are usually more than one speed contest can be held in one same month. In some rare occasions, there can be more than one active Speed Contest at a time. Speed contests usually have more and less expensive prizes than regular contests.3.2 Are contests decided by the staff or the community?It depends on the Contest's specific rules. When an Instructable is chosen by the community, the winners may have multiple categories, such as best rated, most viewed, most votes and others.When the staff decides the winners, they usually take the community's reaction to it as a factor in choosing the winners.3.3 What is Burning Questions?Burning Questions is a regular event in Instructables, where the staff (usually Noahw since he manages it) posts a list of Wanted Instructables that haven't been made.Users submit their entries and the best instructable that answers a question on the list wins a prize. Since there are so many prizes (One for each question), Burning Question Prizes are less expensive, so there can be more prizes.(Originally, the prize was an Instructables Shirt, but as the community grew, more instructables were requested, and the prizes were getting more expensive, so now, the prize is usually a Prize Pack consisting of various Instructables Merchandise)When a winner is chosen, the staff will send him/her a Private Message telling them how to claim their prize.The staff publishes a new round every now and then (currently, we should be expecting Round 5.)Rules:Although the rules are posted in the same posts that the questions are announced, these rules are important, and if not followed, an entry wont qualify: - The Instructable must have pictures in every step. These pictures must be related to the instructable. - The Instructable must be of good quality. It must have proper grammar and steps must be clearly understandable and detailed - The title must be the same as the question, or else it wont be accepted. If the question is how to fold a shirt, the Instructable's title must be exactly that.3.4 Why is Burning Questions Held?Burning Questions has 2 purposes:Getting people to create Instructables wanted amongst the communityImproving the site's "googleabilty". Since many questions start with How to...., it helps the site appear more prominently amongst search engines like Google.3.5 If Burning Questions is chosen by the staff, then why does it have a voting option for the Instructables?Burning Questions winners are chosen by the staff. The voting option is available because Burning Questions has been implemented into the new Contest Section, because of various reasons.Although it is the staff who choose the winners, the community's response to the instructables is also a factor in the decision. 3.6 If I submit 2 answers to Burning Questions, and they both win, do I get 2 Prize Packs?No, if you answer 2 questions in one Burning Questions Contest, the staff will send you a surprise extra gift along with your Prize Pack.3.7 What regions are eligible to participate in contests?Some contest are open to any country, while sadly others are not available for some countries. Take your time and carefully read the rules and details of contests so you can save time or make arrangements.3.8 How can my Instructable get more views?The main thing you can do to get more views is to make something interesting and likable.If you want more views, try posting a forum topic so people can learn about it. Instructables with good and clear steps might even be featured on the Front page- the most trafficked part of Instructables.com3.9 How are Instructables featured? Members who have shown to be very helpful inside our community are handpicked by the Instructables staff and are given the ability to feature an instructable is they consider it meets the criteria for Featuring. As Instructables are featured they appear on the homepage, the most trafficked part of the site. 3.10 What does an Instructable need to be featured?It needs to be good - clear, easily-read Instructions, plenty of useful photos, in focus and probably using your camera's Macro Function (Click here for additional info on using the macro setting) , and additional notes on the images to explain extra points.You should use full and proper language - capitalize sentences, check your spellings and don't use sms-speak. (cuz-because). English isn't compulsory, but correct grammar and spelling are.If it is original idea, a novel approach or an enjoyable read, with carefully-arranged images, then it is more likely to be featured.3.11 How can I be selected to be able to feature?If you produce consistently-good Instructables, and especially if you take an active, useful part in the community, you may be approached by Eric ( ewilhelm ) to join the team. There is no set number of members of the team, but new members are not often invited.4. Miscellaneous4.1 Is it possible to intern at Instructables?-Check regularly at our We're hiring page for more info. Instructables member TimAnderson is also running an internship program documenting Heirloom Technologies 4.2 What is the Community Section?The Community Section contains the Forums:You can choose to either view topics by category or View All in an option at the top of the pageGeneral Forums - General Discussions of DIY. You can talk about anything, not just DIYMarketPlace - Forums for job offers, Internships, Kit sales and other sale sin generalHelp - Ask for help, report a bug, or just give your feedback on Instructables4.3 What is the Marketplace?The MarketPlace is a special part of the forums dedicated to bussiness like Job offers, Interships, Kit sales, and other sales in general.You can sell your stuff, or buy someone else's. This section is still fairly new, so some changes might still happen.5. Current events and Glitches5.1 I just rated an Instructable, but it says that it hasn't been rated yet!The current rating system is fairly new. Before, the rating system was simply the option to give it a plus, or a minus.Our new Rating System is based on the one described hereThe new rating system, consists of the ability to give it a rating from a scale of 0.0 to 5.0. This system is represented by a line of stars. You may also give ratings like 3.5 and 2.5.This new system is not yet complete, and there are a few bugs to work out. Currently when you rate something, it is queued to be processed during Instructables' overnight Bayesian rating algorithm-run and does not update immediately.Until it is complete, you might notice somethings, like for example, that most Instructables will have a rating lower than 4.5.2 I just saw a comment that says it was posted -xx minutes ago! What should I do?This is a small glitch we are currently experiencing. The staff is aware of this, so please, do not report this as a bug or make a forum topic about it. It is nothing serious and out staff are working to fix it. Instructables runs on a couple of servers. Sometimes, the serves receive different information, and when they each compare their information, they might get confused and say that the post was made at a time that is not possible.The following people have contributed to this FAQ:* Kiteman* NachoMahma* Brennn10ewilhelmThanks for your help!I hope this Section has helped answer any questions you might have.Have a question that should appear here? Private message me and I will answer as soon as I can.

Operating a transformer at half the voltage? Answered

What could be the effects of the output when operating a transformer at half its rated voltage, specifically to the amperage? as two examples: If I had a transformer rated for an input of 240v and an output of 20A at 24v and I was to supply the primary with 120v, what would happen to the output? If I had a variac (autotransformer, variable transformer, ect.) and it was rated for an input of 240v with an output of 0-260v at 11A, what would happen to the output ratings at only 120v?

How to store hydrogen under pressure

I've made several hydrogen generators via electrolysis, but every time I failed to store the generated hydrogen under (some) pressure. In this-> http://www.youtube.com/watch?v=m9Q6gDKP2R0 video they used an emptied fire extinguiser to store the hydrogen. The only problem with this is that they use a chemical reaction to generate the hydrogen whereas I want to use a renewable source (electricity).  I have a compressor so I could use that to generate the pressure. Has anyone got any ideas on how I could store hydrogen under pressure? Thanks

Print a working engine in under an hour

Hi, I've got a question to the forum: Does anyone want to functional engine parts and other parts in an hour?  I'm developing a desktop 3D printer that can make a 1 kg steel or aluminum part in under an hour. I'm making this for myself because I want to design/build/fire a working rocket engine in a day, but I'm curious to see what else people would use this printer for if they had it and why they would use it. Comment below if your interested in this printer and say why your interested in it and what you'd make with it:

Instructable newsletter under Promotions in Gmail

I used to get the instructable newsletter regularly but wasn't receiving them recently. The last one was on 10th Nov. I checked the Promotions tab in Gmail and there they were(along with "Latest from Instructables" which never ever made it to my inbox). I've added the email IDs to contacts so they will hopefully end up in the inbox in future, but was wondering if anyone else faced anything similar? I didn't change any settings so it must be some changes at the instructables newsletter end or maybe Gmail made the promotion filtering stricter...

LEDs - Under-volt, over-amped?

My issue: Have multiple LED drivers, (high power LED instructable) and connected the wrong one. The LEDs are not dead. My LEDs are rated at 9-12v, 950mA and I have sets of 4 in series hooked up to a 36v power supply. The driver I used has a .3ohm resistor on it. so it's putting out ~1.3A The LEDs should have burned up. Since the driver eats up a little of the voltage, each LED is getting ~8.75v. Is this why they haven't burned up? Thanks!!
