I want to make some props, and I've stumbled upon the idea of papercraft. Now I'm thinking of making it solid, only using paper as the substrate. I think I should simply cover it in clay, but I figure the Instructables community probably has some tricks up their sleeves. So. Anybody have some nifty tricks, or better materials to use to make a papercraft real sturdy? Maybe even making some costume armor :D Hope I can get into the prop-making/cosplay community!

Hi! Since I'm not very proficient in food making yet, figured it would be wise to ask for advice. Issue: I have many jars of various jams because grandparents make some every summer-autumn season, yet I only consume it once a week on my binge day and even then there's only so much of it one can eat. Preferred solution: I intend to make some sort of candy from the jam. Most likely something jelly-gummy like, maybe dip that in chocolate/mix some nuts in or do whatever else comes to mind. Basically solidify the jam. So how do I go about doing this? Will adding a lot of gelatine do the trick or should I reduce moisture content too? If so, how? Any other suggestions and bewares welcome too as well as other ways of using jam in bulk! Thanks, Raitis

There was a chef I saw one TV once who does some original things with food, for instance, he made a pizza that looks like a chocolate cake. He also pureed pancakes into a liquid, and then put them on below zero plates to re-solidify them when serving. But now, I can't figure out how to find him. Any help would be appreciated.

I recently mixed sugar and potassium nitrate to make a rocket. i ignited the mix and after it was done burning it left a molten pool of what i assume is potassium nitrate. i pored hydrochloric acid on the solidified pool and i produced a large amount of heat and was creating a brown-red gas. the gas was heavier than air because it sank to the bottom. can anyone tell me what this gas was?

Has anyone seen those Bravit Candles? http://www.madeindesign.com/design/images/authentics/Bravit-Animation_440.gif http://www.madeindesign.co.uk/prod-Bravit-M3-Authentics-ref70170.html I've thought about instead of buying some I'd like to make my own (I could also customize the path of the wick then). Any ideas about the best way to make something like these? I'm thinking fix the wick then pour in a layer of wax,say an inch or two, then cool it. Wait for it to solidify (or mostly) then move the direction of the wick and pour in another layer of wax, wait for it to cool and repeat. Any other thoughts?

Hi Really need some help with this one, have searched everywhere but cant seem to figure it out. I know there is probably a very easy solution i'm missing so please help. Basically I want to compress CO2 at around 80 psi into a hollow metal. I have drilled a micro hole and created an opening (about 2mm radius) into the metal. My problem is after I compress the CO2 in there how do I remove the compressor nozzle and seal the hole without the CO2 escaping. The metal is small and there is no place for a valve. Is there such a thing as a self sealing removable valve? Or could I use a valve with two openings and pump liquid metal (that would than solidify) and seal the hole so I can remove the compressor?

I'm just on FIAH with these Topics. But this one's cool too. Via ScienceDaily: A collaboration between researchers from Cornell, University of Chicago, and iRobot has resulted in a robot gripper that conforms to practically any object. From the article: Here's how it works: An everyday party balloon filled with ground coffee -- any variety will do -- is attached to a robotic arm. The coffee-filled balloon presses down and deforms around the desired object, and then a vacuum sucks the air out of the balloon, solidifying its grip. When the vacuum is released, the balloon becomes soft again, and the gripper lets go. This sounds like another hi-tech device that could easily be duplicated by a DIYer. All you need is a balloon, coffee grounds, and a vacuum pump. Update 2 November: Found the video! It gives a much better idea of how the thing works. Via, image from same.

Our Kiwanis club has a roux party every year where a dozen or so people cook roux in cast iron pots over gas burners. Hours of stirring of various liquids, veggies and spices (added at intervals through out the cooking cycle). Cooked until it becomes a solid about the consistency of moist turkey dressing, to be dipped out into a pan and then start a new batch. What we need is something like a small cement mixer with burners. Something that will heat liquid, mix, and dump or we can scoop out when it's solidified. The stirring needs to be constant hence the cement mixer premise. If it doesn't mix well and parts of it burn then the entire batch is ruined. Electricity is available, propane bottles for fuel. Tried thinking through something with two metal cylinders, one inside the other with the gas jets between the two but the rotation part is the issue. Any help will be appreciated, and of course since we are a small nonprofit the cost needs to be as low as possible. Thank you ! Tray10

First: Thank You Already for Considering helping me. I need the shape of the Inside of the balloon - not the outside like papermache'. I tried Canned Foam Insulation "Great Stuff" brand; but it didn't expand and solidify. Then I need to cut it in half to get a hemi-sphere / hemi-balloon shape. A shape like half an egg, but 30" long, 19" wide, and 9" deep if laid on the flat side. Will Gorrilla Glue puff up and stretch out the balloon? Is there some kind of expanding urethane that doesn't need free air to cure? Will a rubber mold making liquid like Vytaflex fill a balloon to it's "real shape" and cure inside without air? http://www.youtube.com/v/MJ9lgZ3V90o&autoplay;=1 is a video of making a sink mold from an existing vessel sink. But I don't have an original of this shape to make a copy of. Ice isn't permanent enough, but would be the perfect slick surface texture. I don't have the tools to cut a 30x19" sphereoid in half neatly. The goal is to get a solid shape with a smooth surface to use as a mold for pouring material over to achieve a "bowl" shape with a very smooth interior surface and a hand formed outer surface. thanks again

This started as a blog post on Make http://blog.makezine.com/archive/2008/05/parallelized_wind_power.htmlIt was suggested to head over to instructables and get some stuff going here and it seemed a good idea. Also, in the meantime I found (of course) a bunch of cool wind projects here (about 20). I really like the vertical Savonius turbines. I wonder if those could be stacked with a similar effect?I've been wanting to do a wind power project for a while, and it seems like a good one to work on with others. Here's a brainstorm to kick things off. Please add to it or suggest alternatives problems etc.- total parts cost < $200- leverage off the shelf parts as much as possible. - little or no machining.- over 100 watts, (ideally 300-500) (this could be totally unrealistic with a $200 price, not sure yet)- usable in small yards, urban roof topsThe guys who made the original did some research for a grant and the paper is available here: http://www.speakerfactory.net/TURBINES/GRANTS/Selsam%20EISG%2002-18%20Final.docAlright. Hopefully this is enough to kick off some discussion and gather up interested parties. I think the first step will be to tack down goals and solidify a general approach. Ideally in the end, we can come up with a good parts list from a minimal number of sources, and an instruction set that's relatively easy. A group might also leverage some purchase power by getting some of these parts in bulk (ie. a whole bunch of airplane props). Tim

It's expensive, untested and dangerous.The idea goes like this. Start with a coffee can foundry, possibly powered with Biodiesel or Propane. Then design a mold for what you want to build using Autocad or some variant thereof. After it's finished, send the design to a machine shop to have it built out of steel. When you receive the permanent mold, melt the aluminum and pour into the mold repeatedly and often.The idea seems like a good one to me, I'll be testing it soon enough using common screw clamps to keep the mold tightly secure.Has anyone here done this? The closest I've come to doing it myself is pouring into a muffin tin.The photo below is a picture of the results which was taken from another board found here, you'll need a login, the photos are located in the forum under Machining and Tooling.Give me a shout if you dig the idea.UPDATE 5/24/07It works! Using my Harbor Freight Mini-Mill I cut out pockets in two pieces of 1018 steel, each about an inch deep, and four inches across. I then cut inlets in both pieces and welded some scrap steel U channel on the tops of both mold sections to form a pool enclosure for the excess aluminum to collect inside of and stay safely contained.Then I lit the candle on my foundry and melted the aluminum while at the same time pre-heating the molds, (connected using C-clamps) in the oven. When the aluminum melted, I poured it and it instantly solidified. After about 2 minutes of running around in a panic I cracked the mold open. The detail level is incredible. Impressions made in the mold with a fly-cutter can be seen in the casting. The casting is bright, shiny, and seemingly devoid of any burs usually associated with unfinished aluminum castings.I'll provide photos later of the test mold and casting.

Baghdad Iraq. It was once the jewel of the Muslim empire and epicenter of knowledge in the Eastern world. Now it is best known for corrupt governance, bombings, and dust storms. It was also my parents’ home. After visiting once in 1991 as a child the few memories I have of Iraq seemed to be shouting matches as my parents yelled over the phone making overseas calls. Names of Uncles I had never met were mentioned and a phone was handed to me and I was left to nervously fend for myself with my weak Iraqi slang and an Uncle who apparently knew all about me while I knew nothing of him. The country was an impenetrable black box to me that would spit out another refugee somewhere in the world every few years or so. Sixteen years later the first wall between Iraq and me was broken. In 2007 my nuclear family had traveled to Syria and for the first time I met family members who still lived in Baghdad. I knew them now. My uncles and cousins grew flesh and blood. I could feel their prickly faces as we greeted with the traditional Iraqi 4 sided cheek kiss. They could graciously give me their dishdashas as gifts. Names finally had faces, but those faces were deep, sunken and afraid. 2007 was a bad year of sectarian war in Iraq, which is why the Damascas district of Harasta was flooded with Iraqis. The sound of construction continued through the night to keep up with the massive (ab)use of the "tourist" visas. I saw something in the Iraqis in Syria that I hadn't seen before; something that scared me. I saw hopelessness. It was then I settled on a long-term project to return to the country and share something that I had just discovered around the same time: the future doesn’t come prepared -- we make the future. The do-it-yourself attitude that was growing in America was being combined with the culture of sharing that you find in hackerspaces, at instructables.com and in open source technology. This atmosphere made anything possible. You want to build a vertical generator without any spinning parts? Sure! How about a walking quadraped robot with a sofa? Do you want to quit your job, write zines and sell them in the crafting circle? Sure! Start a business! Write a novel! Organize a benefit concert! Sure - sure - sure! “Make your own future” was the message. It was a message of hope - it was the message that I wanted to share in the Middle East, and especially in Iraq. In 2011 the opportunity to work on sharing this beautiful message in the Middle East presented itself to me, so I quit my robotics job and took it (sorry Andrew). A few friends and I started a tiny organization called GEMSI - The Global Entrepreneurship and Maker Space Initiative. We funded ourselves through Kickstarter and our first project was a Three-Day Maker Space hosted at Makerfaire Africa. We were hoping to let people experience the feeling of the Maker Movement first-hand. We collaborated with Emeka and the team from MFA, Cairo Hackerspace, along with many amazing egyptians from all over the country. We had a successful first attempt at sharing the message of "Yes you can!” It was a great start, but Iraq was still an impenetrable fortress to me. It took till 2012 and a chance encounter with friends in Cambridge, MA for me to find my first avenue back into Iraq. Via my friends, I met someone who’s friend was affiliated with TEDxBaghdad. A few steps removed, sure, but when I heard about TEDxBaghdad I knew I had found my way in. I knew TEDx and the types of programs they hosted; I knew they were hopeful, inspired, and shared a vision for a brighter tomorrow. I started communicating with Emeka from MFA, who also works with TED, and he put me in touch with Yahay. After my first skype call with Yahay I knew I was going. Someone else had done it - someone broke that barrier, did amazing work in the country, and survived. It wasn't the death trap my family was telling me it was. There was a new narrative being woven and I knew what I needed to do. I booked my flights before I even finalized any workshops. I needed to meet the TEDxBaghdad team. Later, I called my parents and told them I was going to Baghdad and they said, "Shinu?! Inta Makhabal?!" That probably means exactly what you think it does. Needless to say, they had their concerns, but I was going regardless. Now that the tickets were bought, we started planning. Yahay put me in touch with Abdal Ghany, one of the Iraqi organizers living in Baghdad. He coordinated everything. It was amazing. These guys kick some serious planning butt! Ghany basically told me, “Show up and give your workshop. We'll take care of the rest.” This was a welcome change from the hours of facebooking, planning, and coordination I usually have to go through to schedule events. It really seemed like this was possible. I was going to give an Arduino and 3D printing workshop in Baghdad and I was really excited! I sent an email to Sparkfun and Makezine asking them for open source electronics donations since I knew bringing my electronics box through the airport wouldn't be a good idea. They sent me a nice goodie-bag of beautifully packaged Maker products. These two organizations have given me a tremendous amount of help throughout the years, for which I am extremely thankful. I packed a suitcase filled with 2 3D printers, 25 Arduinos, an assortment of other open source hardware and sensors and headed out looking a bit like a bomb development lab. Yeesh! Somehow I made it through China, Saudi, and Turkey without any serious interrogation. Mostly just really quizzical looks from my unzipped bag up back to me... "You're a teacher?" they ask. "Yes," I say, "yes I am." Turkey was the stop before Iraq. Turkey was brilliant, sunny, lush, and seemed to be comprised of mostly happy smiling people walking by the sea. Coming from the deserts of Mecca, this was a welcome sight. I let the green of Turkey wash away the dust of Saudi Arabia. The mishmash of cultures, sounds, foods, religions gave me a great feeling of liberation. This was a lively place and the two hackerspaces I met up with there, Base Istanbul and Istanbul Hackerspace were fantastic hosts. Furkan and I spent a lovely day together chatting about Maker culture as it spreads through the Middle East and then in the end we had a potluck BBQ with members from both hackerspaces by the rocks of the sea. It was great to see these two Turkish hackerspaces and to be reminded that this movement is truly global. My dream of hackerspaces empowering people globally is really possible – and it’s great to know that it is a dream that is shared by others. I left them full of enthusiasm and flew directly to Baghdad. Landing in Baghdad was strange and a bit concerning. Looking out of the window all I could see was a brown cloud. We were landing in a dust storm. I had heard about the turab (dust) of Iraq, but this was the first time I saw it in person, and it would be one of the things most often on my mind. Getting a visa for me was surprisingly easy, except for the fact I forgot my passport on the plane and two guards had to escort me one to each side back to the airplane to retrieve it. But once I had my passport, I told them my laqab, which is the full name that includes ancestry. Showed them a copy of my dad’s passport and my Iraqi birth certificate and I was in. I was hoping for a nice stamp, perhaps with some Iraqi relic on it. But they took my passport and wrote in it: "Originally Iraqi", so there it goes, it's official. Ahmed, my cousin, was not at the airport when I took my paper work and headed out to the lobby. The airport was sparsely populated and heavily regulated. I barely managed to snap a picture before a guard came up to me and had me delete them from my phone. In the lobby I met a man just released from a Swiss prison. The Swiss had given him the option to be sent back home to Iraq, or be jailed. He chose to leave and come back to Iraq. This becomes a theme later as I see more and more people, all of whom desire to leave the country to become refugees elsewhere. It seems that when hope runs out for the country you live in, the only option is to find a new one. This story is one of a million various stories of struggling to find a new life. Each varies in its details, but all have survival at their core. Ahmed arrives 30 minutes late, apologizing. He's wearing jeans and a polo. His hair seemed freshly cut and his face was serious. We had never met before. The only thing I knew of him was that he thought I was reckless for coming. He had been spending hours on Skype with me attempting to convince me that coming would be a bad idea: "You have no idea how bad the bugs are. Just wait till you see the dust storms. The heat will kill you... etc" But once I saw him in person it all changed. I didn't think I'd grow to like Ahmed, but I grew to appreciate his ways and he became like a brother to me before I left. He took me to Mansour, a neighborhood in Baghdad, telling me stories about Iraq as we travelled. This is the neighborhood where the house my dad designed and family built stands. On the ride home we had our car checked for bombs at least 4 times by what Iraqi's call Saytarat, which is the equivalent of a checkpoint and, to me, seemed a total nuciance. They were the reason he was late. What would normally be a 20 minute drive can become three hours long because every car is checked for bombs. They are everywhere; throughout the city, on every road. We passed the guard who watches over my family’s neighborhood, and he takes his hand off his machine gun to wave at Ahmed, and I begin to recognize that weapons, car inspections and burned out cars are normal here, so they don't think to comment on it - like an empty lot in Detroit, or the homeless in San Francisco. We got to my family home with no time to rest. I had to leave to meet up with Abdul Ghany and the crew at a Cafe in an hour and then conduct the workshop in two. Ahmed comes with me - he doesn't trust people we'd never met before and won’t let me out of his sight. I trust first till proven otherwise, he has learned to do the opposite. It’s a telling sign of how different our lives are on a day-to-day basis. As soon as I met the TEDxBaghdad crew, I felt at ease. MNA, Abdul Ghany and the entire crew were thoughtful, hardworking, and inspiring people. I was really happy to have intersected with them and they helped me in more ways than I could count. We first met up at Everyday, a local Mansour café. Everyday cafe was hyper airconditioned and everyone seemed to think it was hotter than it was. The crew was awesome, they were really a great first introduction to the excited young people of Baghdad and they certainly have the famed Iraqi hospitality. But here's a tip: do not order a fajita in Baghdad ;D. Mohammed Al-Samarraie pulled out their iPads and started showing me video production work he was doing for TEDx. Abdul Ghany comes a little late and we have head out to the workshop. The workshop was held in a two story office building surrounded by palm trees. Looking out the the tinted back window we could see the muddy river run past, winding and dark. Slowly the TEDx people started trickling in. Then I started to get nervous. The checkpoints didn't bother me, the tanks in the streets were not an issue, but here were these people coming to learn something from me. What could I share that would really matter to them when they had so much to deal with daily? What could I share that could be relevant to people who see bombings as I experience lightning storms? I have been to other places in the world to share this kind of information, and some of those places have had political problems and ongoing revolutions. But Iraq was the first country I had been to that really seemed like a war zone. I decided that first I needed to learn from them! What were their projects? What did they hope for? I hoped they would learn from each other and get excited about their projects and I wanted to be able to share things that were relevant to them. Thus, everyone was encouraged to talk about who they are, how they learned about TEDxBaghdad and to share their project, share with us their mission, or share an inspiring story. I was amazed to hear about all the incredible initiatives the crew was doing. From intercultural exchange programs, to street clean ups, to historical artifact preservation, each of them shared and I started realizing something. They were not as interested in new technology as they were interested in arts and culture and after hearing about a few of their projects I started realizing why. Learning about culture and paying attention to the arts gives people the ability to pay attention to details. They can look at another human being and see all the subtleties that make us who we are. We each fall in love, we struggle, we question, and have doubts. Arts give depth to a black and white world. Sectarianism is difficult when we pay attention to the commonalities that tie us all together. What would the world be like if anyone who wanted a weapons license was required to have visited India, could pass an art history exam and could play stairway to heaven on the guitar? We were in a sort of office building near the river which ran by dark and muddy looking through the tinted windows. One by one, they stood up in front and gave their short presentations. There were doctors, engineers, and designers in the crew. They each stood up and told the story of how they found out about TEDxBaghdad and it was incredible. Each of them had a friend recommend it to them, and it was mostly done through Facebook. Some people's projects were related to health, culture, antiquity preservation, and connecting Iraqis with the rest of the world. While they spoke I made a graph of the things that connected all of their ideas together. It was a beautiful thing to see. The common themes were to help Iraq as a country through the integration of new ideas and how to bring a new face of Iraq and present it to the world. To have the news about Iraq be about amazing things, inspiring things, rather than explosions. Being in that room with that energy made me feel like we were already on our way. I pulled out the boxes of donations given to us by Sparkfun and The Make Shed and now it was my turn. I told them about my story coming into contact with my friend Alex through instructables.com, how being in San Francisco and Cambridge opened my eyes to a new way of entrepreneurship using communities and open source technology. And how they could make anything they could imagine if they got together to do it. We discussed how sharing and collaboration was a common value that held the entire system together. I used the concept of the LED throwie, which is a simple idea by Graffiti Research Labs to connect an LED to a coin battery and a magnet. They used it to throw at ferrous buildings as a form of electronic graffiti but once they uploaded it to instructables the idea was out there and people were inspired to take it and derive many other projects. You can never know what will happen when you share something or when you create a tool and share it. People created outlined throwies, LED floaties in balloons and finally we start seeing LED floaties which are sequenced to act like a light show at a phish concert. Hahaha! We then talked about the Arduino an easy to use microcontroller designed for artists. It's a bit of technology that is a simple and easy to use platform to build interactive projects. We talked about how the open nature of the project people can use the Arduino and then use shields to add features like being able to connect to the internet or play MP3s. Open source tools make building new products a lot like using legos. We were in the middle of using some of the sensors The Maker Shed had sent us to make a DIY heart rate monitor when the power went out and all went dark except for the LED throwies we had made. It suddenly felt very intimate. We put all the LED throwies in the center of the room and huddled around it for story time. The feeling of connection was palpable for me. Sure the lack of power meant that we were not going to be able to 3D print, but being in the dark with TEDxBaghdad was one of my favorite memories of this trip. The lights went on and we had a long question and answer session / photo shoot. Some of the doctors were interested to use the Arduino based heart rate monitors to replace the broken ones in the hospital. I heard about this and was flabbergast that the most basic and cheap tools I had brought with me might have a direct impact and may even save lives. Technology might not solve the political problems of the country but it seems that there was a lot of room for development and that the crew I was with was creative and excited to make use of it. I passed out 20 Arduino kits that day, including the Lillypad which is a version of the Arduino intended to be sewn into clothing. Although there were very few engineers in the audience, everyone seemed to be buzzing with ideas and ways to use the Arduinos. What a great workshop! I was super excited because not only had they understood the message, they seem to have been infected with the feeling of capability! Now to seal the deal, we were all going to go out and eat a classic Iraqi dish Simach Masguf. Ahmed has been calling me hourly making sure that I was OK, but I felt safe enough with my new friends so we all headed out to a fish spot by the river. Hours go by, lots of fish is eaten, and lots of juice is drunk. Some of the crew smoke some sheesha. It was like I was with new old friends. My Iraqi slang was improving hourly and although we had just met I knew me and TEDxBaghdad we're going to be working together again very soon. I would have stayed all night eating and chatting about future projects and the problems to solve in Iraq, but the cerfew was about to set in and we had to jet. Yeah, there is still a curfew. On the ride home my head is filled with contradictions. Hope and confusion mix in my head as my family rings 4 more times. I get home safe and decide that the only way to deal with the complicated situation in Iraq was to act with irrational hope and optimism. That's the way TEDxBaghdad seemed to work. And that's going to be mine as well. The next day there were five explosions in Baghdad so TEDxBaghdad and I decided against going out to the Iraqi National Museum even though we had to request permission to go. We meet instead back at Everyday and there we solidify our commitment to working for a more beautiful Baghdad and a country which will become a producing nation once again. Sharing with the world it's art, science and literature like it once did years ago. +BG
