Eco buildings for free?

I'm organizing a community lead market garden project within Wales (UK) to help those most in need within our community. We have little to no money for this project as almost 90% of the volunteers are unemployed, privet funding for our project is hard to come by  we have only found about £400, so we are intending to use as much recycled stuff as we can. I really need plans for a con and tire or wattle cob storage shed/ shelter for myself and my volunteers to hide out in when the weather turns bad And also some plans for a soda/plastic bottle green house. If you can help please do as i've not done anything like this before!

Looking for constructive critism

I have not written an 'ible in a long while, but was recently so inspired I wrote...   https://www.instructables.com/id/Make-A-2D-Infinite-Runner-with-Unity/ Luck would have it that a game contest opened during my building of the first prototype (pre write up, to get things all worked out), which spurred me on even more. Anyways, I am wondering how I missed the mark completely, not even worth a feature. I have had way lesser projects featured....and well, I was only inspired to write this to share. Anyone who has been writing here for any amount of time knows that you need to be featured to be seen. I gave detailed step by step instructions with many pictures well commented...or thought I did. I did something original (Not many game making tutorials here, only 2 other unity ones, and they are on older versions.) I thought the demo game download was a nice touch.  So I am curious for suggestions on how I could spruce it up enough to be considered as a feature. I believe that people would enjoy the topic, and more importantly, I feel people would like to make this or use this as a springboard to their own version. Was using the robot a big faux pas? I see so many other features that use him and thought it was a good idea. Is the game itself that visually unappealing? Perhaps foolishly , but I love the look....I was...even more foolishly...proud of it. It wasn't something I just knocked out, but rather something that a lot of time went into. Time that was truly wasted if it is never even seen. Discouraged. Any suggestions  to how to make it better would be welcome.

Drones, not just for spying

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

while making a tent like shelter systems how to decide the position joints in space where the two poles will intersect?

I have several other questions in mind... 1. since the PVC conduits are bent during the process of building tents, some bending stresses will be induced..how do we ensure that the structure won't fail? 2. Can someone suggest some modification in shelter systems dome design to make it more stable but not adding much complexity and not adding much assembly time? 3.Can someone give a construction plan of a dome similar to shelter systems, different pipe sizes and position of joints??

Rant numero # 2

Well after seeing the same commercial like 3 times in a row (don't ask, my cable company is dumb as hell) I got a little fed up. These commercials about donating money to save the animals, save the african children that happened because lack of control. Face it people, these people only want your money, why do you think there's so many different commercials and ads from so many different companies/organizations? We'll start with the money thing. They tell you it only costs a dollar a day or some silmilar bullcrap so you can save ONE child. Here's the catch, they usually tell you that 40 cents of each dollar or the such will be sent to africa/said child right? Well that 60 cents they keep probably can be safely said that it adds up to a profit, yes? Sad.... If I want to help a child out in africa, I'll put $20 or however much of their money (Go to a exchange building people!) in an envelope and mail it down to them africans, I'm not going to pay someone 60% of the total donation just to take it down there. That's BS, why are people so screwed up? But hey, some people are probably thinking, why would we help africans right? That's BS eh? Well yes and no. While helping out your fellow humans, it's about the nicest thing you can do and I expect you to do it, there is a point. There is a whole nation, and we're supposed to just lift them off the ground and feed them, clothe them and give them money. Why are there so many people that there isn't enough food, shelter, or said clothing in the first place? Lack of self control obviously and they need to realise that you can't just have 10 kids these days and it's all cool, due to the cost of things these days (or at least that's what the government wants you to think). It wasn't me that made the african make so many kids, why should I donate? There are many looks and points of views that can be taken and I guess it's the fact that everyone looks at things differently in some way that these organizations take advantage of that. I could be wrong, but hell, who wants to argue me?

can you grid a saw into the back of a knife? Answered

Want a sawback knife, not willing to spend 70$ on one just yet. So with a file, a hacksaw, and some sharpening stones, could one easily make a "saw" or some very coarse serrations on the back of a knife suitable for bush craft and basic survival/trap/shelter construction? wouldn't need to cut down a tree, just make notches in branches for traps, and basic things like that.

I would like to make a simple machine that allows me to roll newspaper logs tightly?

You know those log making machines you can get that let you make your own logs? Well I have seen some amazing furniture made with very tightly rolled newsapers that is so strong that when knocked together it sounds like metal bars. The machine would need to have 3 rollers and a handle for turning the top roller. the loosely rolled newspaper would sit on another 2 rollers and be rolled like a giant hand-rolled cigarette until it was tightly packed into a rod. I wondered if there was some way of either making this from scratch or improvising something? Thanks.

acceptable angle of deflection for temporary support

Hi, I am in no way an engineer.  I'm trying to figure out what is an acceptable angle of deflection for a combination frame and hammock support.  I'm thinking of using the the 80/20 t-slot beams.  I want something that is portable, easily assembled/disassembled for moving, and lightweight.  I'm go to make a box in our garden to protect our plants and when the corn is big enough, move the box around to make a hammock support(chicken wire around the bottom part to keep the critters out).  It's basically a box 6 feet wide, 8 feet long and about 6 1/2 feet high. 4 beams to make a rectangle on the bottom, 4 uprights(1 in each corner), and another 4 beams on the top to make it more rigid.  Chicken wire will keep the pests out but let me in to relax until the corn is too high and I move the frame.  :)  I'll put the hammock diagonally from pole to pole; total weight with me and the hammock is about 250 pounds.  It will be anchored to the 2 uprights with 300lb chain at each end. Using the angle of deflection calculator from 8020.net, I found some beams that had 5mm deflection with 150lbs of dead weight in the center of the 6 foot span.  I thought that even if I anchored the hammock to the center of the 6 foot span, that would be 300 pounds, more than the 250 max the hammock and I will be.  And anchored in the center of the beam is the worst case scenario since I'll be anchored to the corners. But is that an acceptable amount of give in the beam?  It's not meant to be permanent.  I won't be in it more than 2 or 3 hours tops. Thanks!

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.

Math formula(e) needed: tesseract model construction?

Although I CAN do this without the math formula(e) to figure it all out, I would like to have it for a quicker method of figuring out size, etc. so I didn't have to use up so much material in guessing. I would like to construct the tesseract I have pictured here, using rigid clear plastic sheets or panels.   Given a said size for the "inner cube" say 2 inches (approx. 5 cm or about 51 mm) what formula(e) must I use to calculate the panels' dimensions to connect to the larger cube (knowing full well this will depend on the size of the larger cube....say approx. 4 inches across (about 10 cm or 102 mm)? The reason I'd like the formula(e) is that I may need to increase the size of the center cube by an inch or so, and this would allow me to do so without having to go through the "trial and error" thing so many times. I would, of course, want the center cube to be "centered", if possible or shall I say as close as possible. Thanks....

Iron Man 2 Kinetic Sculpture?

For those who have seen Iron Man 2: In that one scene where Tony is in an office with Pepper on the desk there's that sculpture on her desk. I did some research (A.K.A googling it) and found that it's called the Swinging Stick Sculpture. Do you think its possible to construct one out of wood? It would be so awesome :P

Dragon Samurai chapter 2

Hi! I decided I would post every chapter I do instead of just the first so here's the second chapter! Enjoy! Chapter 2 The traveller After eating some delicious noodles we decided to go to my house. I expected my mother would shout at me because I hadn’t made my bed, but when I got home there was a very different response. My mother looked very frightened. Suddenly my father walked in. He too was a samurai. He was dressed in samurai’s armour and had a katana and a wakizashi (Samurai sword and dagger) which were placed in their sheaths. He only wore the armour in an emergency and in times of war and the expression on his face told me that there was bad news. “Pack your bags, Ryu,” he said. “It’s time for you to go to the dojo.” “What?” I asked in disbelief. “Go and pack your bags,” he repeated. “Hiroshi, you must also get ready. Go home to your father who is waiting for you.” “Yes, sir,” he replied. Hiroshi never questioned my father’s decisions. “Father?” I started. “Do not question me, Ryu. Now go and get ready.” Hiroshi ran out the door and I went to my room and opened my cupboard. Inside were all my kimonos and my bokken (wooden sword). I grabbed my favourite ones and came back to where my father was waiting. I didn’t have time to say goodbye to any of my friends. We walked outside where my father’s horse stood ready. “Hello, Diamond,” I said. He whinnied when he saw me and put his head under my arms so that I could pat him. I scratched his ears while my father prepared the saddle. We named him Diamond because of the diamond shaped mark on his forehead. The white stallion was very rare and my father was lucky to have found him. I still remember the first time we met Diamond. My father and I were travelling on a large dirt road when it started to rain. The road quickly turned to mud so we took shelter under some trees. Hearing a sad whinny, I looked around and found a white stallion lying in the mud. I turned my father’s gaze to the horse and we walked over to it. It was only half awake and had a huge cut in its side. We brought it back to our stables and healed its wounds. It became fond of us so we decided to keep him. He was easily the fastest horse in the city. Back to the present, we set out on the road to the dojo. As we left the city I could see almost everything from the palace down to the pier. The gardens at the top of the hill were full of flowers and shrubs. It was bordered on two sides by a thick hedge. The pagoda was in the middle for people to visit. I realized that I had never actually visited the garden. There were many things I hadn’t visited in the last fourteen years. I would miss the beach with its crystal clear waters and sandy shores. I’d miss the constant movement of the waves. I’d miss my mother and younger sister. I’d especially miss all the friends I had. Leaving Hiroshi would hurt dearly. As we travelled I helped Diamond’s tail to flick away the flies. Diamond galloped so swiftly that it was comfortable riding him. The white stallion sped past villages and mountains until we arrived at a forest. The entrance to the forest was shrouded in mist and there was complete silence. Entering cautiously we heard a weak yelp. My father stopped and stared in the direction of the sound. I dismounted and walked toward the faint voice. My father told me to take my bokken. He always thought that curiosity was a great teacher. I got closer and heard a twitch. Behind a small bush a girl was lying unconscious. She looked about my age- fourteen or fifteen, maybe? She had a deep cut in here wrist that seemed to be from sometime of weapon. She had a large bump on her head which must have left her unconscious. The thing that really surprised me was her hair. It was the colour of gold. I called my father over to see. He stared at the girl and then picked her up. “The healers from the dojo will be able to heal her wounds,” he said. “Put her on your lap and make sure she does not fall of the horse.” I laid her on the horse and put my bokken between me and the saddle holding the girl in place. We continued our journey through the woods without another word. Halfway through the forest the girl started to wake up. She had crystal blue eyes that stared straight at me. “Danger,” she said before drifting back into unconsciousness. I had a bad feeling about this.

Roof deck over synthetic membrane: water intrusion?

Oops, so I posted this in Outdoors before I found Home. Double posting is irritating but it's kind of relevant to both... I'm new to the forums here (long time reader, infrequent poster), if I just committed a major faux pas, gimme a heads up and I'll take one of these down! Anyway, so the back door of my 3rd floor apartment opens on to what amounts to a raised back yard; the only problem is that this "back yard" is the roof of a 2 story addition to the brownstone I live in, and I'd rather not put my foot through a very expensive roof. I've been looking into decking, and right now my plan is a contact-only solid frame all the way around the perimeter of the roof, with a lip extending over the edge of the roof (to supply stability without puncturing the membrane) connecting to the actual frame of the deck which would of course be placed over the top of the brick walls of the building. From there I was going to face the deck with synthetics, probably with struts placed along the horizontal struts of the roof connected to both the upper deck and sub-deck cross bracing (depending on what materials I use/can afford and their relative strength). My hope is to find a way to make the deck in modular pieces that can be removed for when the roof inevitably needs to be resurfaced. So basically it would be large squares (or irregular shapes, whatever) that would sit on top of the struts/cross bracing with the help of a few screws and provide the deck surface. What I'm worried about is water intrusion at the contact points, such as around the edge of the roof and on top of the studs in the middle of the roof. I know synthetics are much more resistant to this type of failure than older materials, but are they impervious? Where do the pros put contacts so water doesn't leak into the floor below? Even if you minimalize it, the deck will have to come into contact with the roof at some point, or you've found some fancy new way of building I'd love to hear about. A few other thoughts are footprint: the building is an 1890 Richmond row house, could this be done with a small enough profile to increase the value of the property without damaging the "drive by" value? (I was picturing an iron railing to keep the project semi period, and this roof actually connects to the big hulking wooden fire escape, so it wouldn't be marring a virgin landscape) Also, do you think any building codes in the country would allow L bracing and big old bolts to hold the structure of the deck together instead of end-nailing the boards? It would make removal for roof work a lot easier. For the corners, would it be better to miter the ends at 45 and run a bolt through the two of them, end nail an L joint or use a thick metal l bracket and a few bolts to hold the joint together? That was kind of an intense post, I'm just looking to shoot the breeze a little bit with anyone who has any thoughts. Everybody always has their perfect way of doing things, on such a big, high pressure job (if this goes south I'd be poor AND homeless!) I want to really chew on the idea a little bit first. Thanks to anyone who actually read this far!

Paper Airplane Contest 2 (Closed)

In hopes of seeing more paper airplanes and innovative designers on Instructables.com, I have decided to host a second mini-contest. My goal is to stimulate the paper airplane channel and encourage more paper airplane builders to post their innovative designs. Requirements: 1. Aircraft Requirements: • Stability at all operation speeds • A minimum glide range of 30 feet (9.144 meters) • Durability to fly 30 feet or more after 15 flights • Use of less than 15 inches (0.381 meters) of tape in construction • Use of less than 5 pieces of 8.5 by 11 inch (A4) paper in construction • Ability to carry at least 6×100mg toothpicks • Provisions for landing gear and/or skids 2. Instructables Requirements: • 1 page strictly devoted to materials required in construction • 1 page explaining how to fly the aircraft • The instructable's license must be: "Attribution Non-commercial Share Alike (by-nc-sa)" • The sentence and link (see below) publicly indicating the instructable’s acceptance into this contest The sentence which must be displayed on your intro page: “This instructable is an entry in Paper Airplane Contest 2 (Instructable URL).” Prizes: For this contest I will award the publishers of the top 5 performing paper airplanes* one patch each. The first place winner will also recieve a 3 month Pro membership. By default, these patches will be medals (1st place, Patch with Gold Medal image and 3 month Pro membership; 2nd Place, Patch with Silver Medal image; 3rd Place, Patch with Bronze Medal Image; 4th Place, Patch with 4th Place lettering; 5th Place, Patch with 5th Place lettering). If the winners of the patches would like a different image, there will be a 24 hour period between the announcement of the winners and the awarding of the patches. During this time, the user would need to send me a private message with their desired picture. *Multiple entries are allowed. To keep the distribution of patches wide however, each entrant can only win one prize. How To Enter: To enter this contest, you must send me a private message entitled “My Paper Airplane [Member Name Here]” with your instructable's URL included. I will then put the link and author's name onto a list on this topic under "Current Entries". Judging: For this contest, I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance rather than shape is a more objective approach. The contest begins Friday, January 14, 2011 and ends Monday, February 14, 2011. Entries must be published before Friday, February 11, 2011. From February 11 to February 14, I will be judging all entries. I will announce the winners of the contest on Tuesday, February 15, 2011 and issue them their prizes Wednesday, February 16, 2011. Current Entries:

How to construct a timing circuit for a LED lighting circuit.?

I am new to electronics but a quick learner. I have a dark path that I want to illuminate for about 2 to 3 minutes using a commercial LED light. It is too far to run a 120V line, so I am hoping to use a 3 - Volt Lithium battery connected to a timer that will shut-off the light automatically. I cannot use a motion sensor as the path is lined with trees that would set it off during windy sessions. I am hoping to be able to push a normally off button, have the LED bulb illuminate and, after I have walked past the darkened area (2 to 3 minutes) automatically turn off, I need two units, one at each end. Also, can I adapt the lighting system to solar power? I really don't want to replace batteries often. Can anyone help me. I can solder, follow a diagram and instructions. I will enclose the unit and make it as maintenance free as possible. If my choice of battery power is wrong, please advise me on any improvements. If  there is a commercial timer available please let me where I can buy it incase it's too much for me to build. Thank you.

Mini Weapons of Mass Destruction 2

Toy inventor John Austin released Mini Weapons of Mass Destruction 2 (Chicago Review Press) this past October. This awesome sequel to the Mini Weapons series includes over 30 new mini weapons with which to terrorize your office with. Here's an excerpt from the press release: "All the projects in Mini Weapons of Mass Destruction 2 are built from inexpensive, commonly kept items: binder clips, playing cards, rubber bands, markers, clothespins and discarded packaging materials. The projects - modeled after real-life gadgetry - range from "sidearms" and "weapons in disguise" to "villain mini weapons" and "surveillance and intel" and cost mere pennies to assemble. This easy-to-follow primer also features plans to construct periscopes, bionic ears, grappling hooks and code wheels. plus, each project includes a supply and tool list, italicized safety tips and step-by-step instructions supplemented by clearly marked, illustrative diagrams" I managed to get my hands on a copy and made the Grappling Hook Gun; the project was easy to follow and my project came together in under 30 minutes (including the time it took to snap a few pictures). My grappling hook went about 20 feet and I'm sure it could travel further with a few minor tweaks! So if you're reading this while sitting bored at your desk, take a look around you. If you're surrounded by un-used rubber bands, pen caps, and markers, perhaps it's time for you to assemble your own office supply arsenal! For Authors outside Canada, USA, UK and Australia The first 3 comments left here with a picture of your own version of an office supplies mini weapon of any type will receive a free copy of this book! All books have been claimed!

How do you construct an illuminated kitchen backsplash? Answered

 I'd like to know how to construct a backsplash like the one shown in the included image. I've hired some guys to help me install a new kitchen and we're almost finished. They sent me to IKEA to get a backsplash, but what I saw there wasn't impressive at all. IKEA only has these ugly plastic 24" sheets under the brand name 'Fastbo'. They're a joke. So I looked on the internet for something that looked better, and found this illuminated panel.  We've already installed 14-2 cable in 3 places under the wall cabinets for undercabinet lighting. But we just assumed we'd be using those undercabinet puck lights. Then I found this picture and I want to do this instead. What will we have to do to reproduce this? What materials? What kind of lights? Where will the cables go?   I assume the panel material is plexiglass but maybe I'm wrong.  If the image does not show up in the post, you can see it here:

Cabins/shelter from garbage/recycling and then some- new site/blog- and INDIE BOOK released

D.I.Y. Micro-Shelters: NEW indie book-forum/site- w/cabins from garbage/recycling and then some I figured it was about time to get up off my arse and get an actual account here, as on a few other sites I constantly(!) read. I'll also post a few of the "constructed-from-roadside-trash" cabins I've built soon- here and on my own blog/site (if anyone's interested, if not, I'll resume beer drinking, and general relaxation). I'm also in the process of building a 16 square foot multi-purpose, mobile cabin-sleeper/sauna/greenhouse/ice-fishing shanty that I'll eventually post upon (its one of three cabins in the works in my Sanford N' Son-like backyard)- yeah, my wife is a trooper! http://www.relaxshax.com http://www.relaxshacks.com In the meantime, after WELL over a year of illustrating and writing, I've now finally completed (through tiny yellow house press) my own small houses/cabins book "Humble Homes, Simple Shacks, Cozy Cottages, Ramshackle Retreats, Funky Forts- And Whatever The Heck Else We Could Squeeze In Here." Clockin' in, coffee-table-book size, at just over 100 pages filled with avalanches of sketches and redneck-thrift/yankee ingenuity projects and ideas, I'm now selling a small initial run of these hand assembled books (you can find all the details on the blog/post). Building your own windows, doors, solar showers, rainbarrels, bridges, furniture, and more from recycled crud, is all covered within. Inspirationally, the books owes good parts of its existence to the work of Lester Walker, David and Jeanie Stiles, D.C. Beard, Dan Price, and Lloyd Kahn. All in all, I'm a small-house book junky, and after the well started drying up a little (I've bought and read all the decent ones I could find) I decided to write my own. Anyway, thanks for looking, and I'll get some small house photos up soon! Happy belated new years to all! -Derek "Deek" Diedricksen

Dirtmobile?

So I got this awesome idea to make a trike with a snowmobile donor. Use the snowmobiles motor and track for the rear "wheel", and a gokart style front end, with 2 wheels, spindles, maybe suspension, etc.  Nothing too big, maybe 400cc or less. 2 stroke of course =D. I am proficient in fabricating, welding, and have a full auto shop worth of tools, so the actual construction shouldn't be a problem. However, I need to know some things about the snowmobile drive train.  Would the track itself work on dirt, light mud, light puddles (2-4 inches deep), and maybe some sand? If not, are there any tracks available for such terrain? Do most snow mobiles have the engine mounted infront of seat, below, or behind? This thing looks wicked cool in my mind.  OH, heres a good way to put it. Like a snowbike (Dirt bike with tracks in back), with two front wheels. Or a honda ATC with tracks flipped rear/front.

Construction materials and hardware used to construct the pommel horse, aside from the aforementioned basics. i.e, use of a solid core like 4 8'x8' posts, a circular tube, or variations to achieve the desired dimensions/ If the design includes the bread loaf taper, how was this achieved? How the pommels were attached and the hardware used.    If the pommels are fabricated how was this done, but lets assume they will be purchased. Variations of supporting base structure is acceptable. Answers need to include how supporting base is attached to the horse and what hardware or means of attachment are used.     A. If leg supports are adjustable, by way of circular tubing or square tubing with holes that can be locked into place, are they prefabricated?      a1. How were the adjustable height leg supports constructed. For example, Think of sliding a smaller pipe into lager one, or square tubing for that matter.        a2.

We're looking for someone to realize the ideas into physical window installations including sourcing the materials, building the various components, and installing the elements. The three different displays contain the following elements: 1. an interactive window wherein passersby initiate the activity by pressing a sensor on the window. This activates two small objects to release from the ceiling and fall into a receptacle. 2. two monitors or displays of some sort (could be a projection) which display two Facebook pages with live updating. 3. a large-scale printout with attractively merchandised objects. This is a contract/short-term freelance opportunity. Applicants should have relevant experience in electronics and physical construction. Email melinda@helpineedhelp.com if interested. Thank you.

K'nex Challenge 2: 18th Sept - 11th Oct - FLIGHT

After the success of the last contest, Gmjhowe, =SMART= and myself decided we'd go for it and launch a second contest.The first we really enjoyed and saw some awesome entries. This time we've decided to make the guidelines a wee bit looser so you can use your imagination more. We'll be setting a category for you to design and build within and then provide you with some example ideas to get you started. And this category is....FLIGHTAnything plane, helicopter, glider, flight related is allowed. Please read the rules carefully.Rules:Your entry must do something. It can't just be a model of a plane or a helicopter. We want them to move or glide or have spinning parts or be functional for something else around the house but be aircraft themed.Entries must be over 50% knex. The remaining can be paper, glue, card, tissue paper.... anything!To enter, write up a full instructable of your construction process with clear pictures and descriptions. Post the link here.Please steer clear of guns. That's not what this is about.Starting and closing dates are GMT.What the judges say goes!Have fun!Judging - 12th Sept - 18th SeptSuggestions:A propellor. Small and compact, if you design a good one you might get extra kudos if your design's then used in loads of other entries.A ceiling plane. With a plastic propeller on the front and the top attached to a string to the ceiling, this plane will fly itself around in circles on a string.Paper plane launcher. Probably the closest you'll get to a gun.A vertical launch rocket. Rocket being a rocket model not a meagre collection of rods.While knex by itself might not be light enough to fly.... perhaps you could run some string through the middle to make it appear to glide.... Mum's washing line might be of great help.Prizes:There will be patches for prizes. Gmjhowe will be uploading them soon.

Need help finding easy materials for Pyramid Head (Silent Hill 2/Movie) costume!

I know there are a few topics and instructables on how to make a Pyramid Head costume already, but mine's going to be a bit different. I'm going to sort of be mixing costume styles of the Pyramid Heads from the Silent Hill movie, and the second Silent Hill game where he made his debut. I have past experience with this costume, actually. In fact, it was the first costume I ever made myself. My mom and I originally made the helmet out of posterboard and duck tape, but it didn't hold up so well after a while, plus it had a problem where it would get somewhat lopsided, or if I turned my head, the helmet would stay in place. This is because there was nothing inside the helmet to support my head when I turned it, or to keep it to where it moved and stayed upright with my head. The robes I made out of a bloody labcoat/doctor's coat with ripped off sleeves, and a bloodied cook's apron. draped over it to conceal the buttons. Made it look kind of odd with the layering, but I worked with it. I used a pair of white female dress gloves with it, because they looked alot like his. Anyway, this year I was wanting to revamp the costume, and add in a bit more detail, change the style a little. I was wanting to make his helmet more like the Movieverse's helmet', with the sharper angle, and grating on the sides. But I wanted to keep the apron that he had from the second game, since I don't really have the figure for the really ripped PH from the movie. So I come to you all for help. :) I need suggestions for this.  I'm also working on a bit of a budget, and I'm not at all good at woodworking. So I can't use anything like fiberglass or actual metal, I don't believe. I want it to look good, look pretty authentic and recognizable, something people could come up to in conventions and say " Dude, that's awesome", but with easy to find and work with materials. I've never sewn in my life, either, so that's out. My first one I'd like is for his helmet. I already have a decent idea of how to make it. This time I'll probably be working with super glue instead of duck tape this year. Duck tape's a miracle tool, but there's only so far it can go in certain rare situations. Something like a helmet the size of a small child requires a certain amount more work. For the helmet, I'm probably going to be using window mesh like the kind used in certain windows or porch doors for the grating on the sides of the helmet. I got that as a suggestion from another instructable, and after a bit of testing how well I can see through it, I think I can work with it. I think assembling it will be easy. I may tape it together first just to see what it'd look like fully constructed before I glue it, though. My main issue with the helmet will probably be support. I need to be able to turn my head, have it move with me and my body when I'm turning around and navigating certain areas. Does anyone have any suggestions on a way to make it do that? Again, it can't be incredibly expensive. ( About more than 20-25 dollars in this case scenario.) A second bit of help I'd need is his skin. Now, my skin's naturally very pale, but there's the problem of hair. I could try applying some kind of makeup to it, but I imagine it'd smudge badly by the end of the day. If I did that, I'd probably have to wax my arms first. x.x The problem with that is that people would probably want to hug me throughout the day, and I'd be smudging makeup on their clothes. Another idea I had was trying to find a white leotard or something similarly tight-but-thin to use as his skin. I'd be able to dirty it up a bit to make it look like his. Only problem is, I don't know where to get one. There aren't any specialty stores around in a fifteen mile radius that I know of that would sell them, and I can't order online for specific reasons. Does anyone know of any widely known store that would possibly sell leotards, or something similar that I could use to cover my upper and lower body? I know white hose or thin white stockings would work for his legs, but it's the arms and upper body that are bugging me. The last bit of help I'd need is for the Great Knife, his BFS. I think I'll also be making it out of thick posterboard, possibly layered with cardboard as well, painted silver. But I wanted to know if there's a better way. I made a really ramshackle Great Knife before out of posterboard, but in retrospect, it resembled more of a giant paddle. XP It's not much diffirent from a buster sword, but most of the Buster Sword instructables I see here are only with wood. And again, horrible at woodwork.  For the handle of the blade, I was probably going to use the handle of a paintbrush or large cleaver. Anything better you all would suggest? Sorry this is such a long read, but I desperately need the help, and I wanted to get a head start on it before October (the date of the next convention in east TN, I think. And Halloween. ). Thank you in advance to anyone who can offer suggestions. Again, I'm working on a bit of a budget, though. The most I can spend per item is about 20-25 dollars. Shameful as it is to say, I normally get most of my material for costumes from thrift stores, surplus stores, and flea markets. I feel bad that I can't sew or do woodwork like the awesome cosplayers and craftsmen on the site.

How do I make something respond to pressure/movment with 2 discrete sounds and vibrate too? Answered

I'm looking to construct an internal module for a toy that would make the toy interactive for my little brother. I'd like the toy to respond with two sounds, one for a different level of touch pressure or movement he subjects the toy to. I'd like the sounds to be recordable so I can customise them. I'd also like the toy to vibrate whenever it responds. I've mucked around with RC cars and what not, but this exceeds my previous experience. Nothing like being ambitious, eh? Also, any tips on where I can find the parts I'd need (preferably in Australia, but if not, then cheap international options are fine) would be much appreciated :)

Could I use this LED driver to drive a laser diode? Answered

I've been trying to construct a blue laser for my friend using KipKay's instructions, but I don't have a good driver for it. If I add an extra current limiting resistor at the end of it, will this (http://www.dealextreme.com/p/2-7v-6v-3w-cree-circuit-board-for-flashlights-15mm-2-7mm-25518) LED driver provide a good regulated output for my laser? If not what else could I use to regulate the output?

How to make a 737

Southwest has put out a video showing the construction of one of its newest Specialty Planes. It's all done in just 2 minutes, 30 seconds, too. It's like watching a kit being put together. Also love seeing the application of the paint job in a succession of masking and painting. Check it out and be sure to mute the soundtrack. via Core77
