The Library is open!!

I love libraries. I love them hard. Yay, libraries!  Knowledge is free, and I think books should be free, too (unless I write them. Then you should definitely pay for them.). So, I'm giving away book patches to everyone who asks until tomorrow at 5 PM CST OR until they run out! :0  So apply below! Post your favorite book, and the book title you want to be in the patch (if different).

OPEN DESIGN RESEARCH

ANSWER: opendesign@gmx.de Dear Sir or Madam, dear creative worker, dear developer and designer In consideration of growing interest in open development processes and their spreading, we are trying to get to the bottom of the »open design« phenomenon. In the course of our investigations we are very much interested in your opinion. The survey consists of a few questions related to hierarchy in open projects. At the end of our observation there will be a theoretical study, which all participants may receive a digital copy of, if so desired. (Just note that the final work will be written in German) First we would like you to answer eight questions according to a given scale. You are free to add a short comment to each answer. Finally there are two questions, which allow for a more detailed answer. 1. Does "Open Design" have a future? (No) 1 2 3 4 5 6 7 8 9 10 (Yes) Comment: 2. Is there a danger of losing individuality due to the openness of a project? (No) 1 2 3 4 5 6 7 8 9 10 (Yes) Comment: 3. Does the loss of individuality imply a decrease in quality? (No) 1 2 3 4 5 6 7 8 9 10 (Yes) Comment: 4. Which hierarchic structures exist in your project? In which relation are the numbers of initiators and participants? (Initiators) 1 2 3 4 5 6 7 8 9 10 (Participants) Comment: 5. Who has the power to decide which changes to implement? (Initiators) 1 2 3 4 5 6 7 8 9 10 (Participants) Comment: 6. Open processes may result in a vast variety of designs. What kind of rules & restrictions are set that may influence individual freedom in order to maintain a high level of quality? What is your ideal conception? (Many restrictions) 1 2 3 4 5 6 7 8 9 10 (Much freedom) Comment: 7. How much expertise is needed to participate in an "open design"- project? (Expert) 1 2 3 4 5 6 7 8 9 10 (Amateur) Comment: 8. Are there moments when it depresses you that open design projects cannot easily be closed again? What kind of moments are this and why do you still stick to open projects? (No) 1 2 3 4 5 6 7 8 9 10 (Yes) Comment: 9. How are complex assignments broken down to many individual tasks and how are these tasks distributed among the participants? Where are the limits of each competency? Comment: 10. To what extent do you understand yourself as the actual developer of a product, that you are working on together? Which kind of copyright protection is used? Comment: In case you would like to dig deeper in this topic, we also offer a more comprehensive questionnaire. Many thanks and kind Regards, Manuel Milde und Sebastian Piatza (Faculty of Design - University of Applied Sciences Dresden)

Open-Source Warfare

Open-Source Warfare is an IEEE Spectrum article discussing how information technology and the internet play a pivotal role in accelerating the adaptation of individuals against organizations through asymmetric warfare.Robb calls this new type of conflict "open-source warfare," because the manner in which insurgent groups are organizing themselves, sharing information, and adapting their strategies bears a strong resemblance to the open-source movement in software development. Insurgent groups, like open-source software hackers, tend to form loose and nonhierarchical networks to pursue a common vision, Robb says. United by that vision, they exchange information and work collaboratively on tasks of mutual interest. The reliance on IT also enables open-source groups to identify and respond to problems much more rapidly than a more structured, top-down entity can--be it the Pentagon or a large software company such as Microsoft. According to some estimates, it now takes Iraqi insurgents less than a month to adapt their methods of attack, much faster than coalition troops can respond. "For every move we make, the enemy makes three," U.S. Brigadier General Joe E. Ramirez Jr. told attendees at a May conference on IEDs. "The enemy changes techniques, tactics, and procedures every two to three weeks. Our biggest task is staying current and relevant."

"opened & fixed" logo

Hi everybody, I think it would be nice to have something like an "opened and fixed" logo. The purpose being to print it as a sticker, then, for example, when you open and fix an appliance, you can put the sticker on it, and when your friends ask, you can delight them talking endlessly about your endeavor. Irony aside, I think it can be an interesting counterpart to the "warranty void if removed" labels, also encouraging people to open and fix their own devices. There could also be an "opened and hacked" logo. I was thinking in something simple, like an "O&F;" with a circle around, or maybe the circle made of a screwdriver. I'm writing this due to my lack of design ability, in hope that someone with that ability finds the idea interesting enough to give it a try. Also, what do you think about it? is it a good idea? would you use it? Cheers, Andres. P.S.: If you think it's worth trying but nobody with technical skills shows up I can try creating a first version on Inkscape.

Can't open newsletter

I'm having a very strange problem with the Instructables newsletter. Starting a month or two ago, the newsletter arrives in my inbox (I use webmail from my ISP, Shaw Cable), but I am unable to open the message. Normally I just click on the message and it opens, but when I click on the Instructables message nothing visible happens.I normally use Firefox 3. Today I tried it using IE 8 and got a message saying that some of the content would be delivered using a non https connection, blah blah blah. I said go ahead anyway, and the message opened, but none of the images displayed.So, it appears to be related to some setting in Firefox, or perhaps some javascript thing that works in IE but not firefox, but I can't figure it out. Can you give me any tips that might help me get it working in Firefox?Thanks,Steve

Easy spray/liquid *open cell* foam?

Hi all - new here  :)  I was trying to think of where I could ask this and I immediately thought of instructables.  Does anyone have any ideas where I could find a spray or liquid *open cell* foam?  It's easy to find cans of spray closed-cell foam these days, but I've never seen one for open cell foam.  I've done a lot of searching, and the only open foam cell solutions I find tend to be giant expensive things for insulating houses in bulk, nothing for small scale applications.  I'm looking to fill a bundle of relatively fine tubes (diameter TBD), which I want to act as a sponge on the inside, resisting allowing the liquid inside to drain out while still allowing for gas migration.  Hence closed cell is not an option.  Polyurethane is probably fine, although other materials may well be fine as well. Any ideas?

MIT Open-couseware Helps Physics Professor Become a Web Star

Open-courseware is helping some MIT professors gain much deserved recognition. While I never took a class from Walter Lewin, I did watch a Nobel laureate (before he won the prize!) ride that same rocket-powered tricycle across the stage of 26-100 (I wrote a little bit about that here in a comment).At 71, Physics Professor Is a Web StarCAMBRIDGE, Mass. Walter H. G. Lewin, 71, a physics professor, has long had a cult following at M.I.T. And he has now emerged as an international Internet guru, thanks to the global classroom the institute created to spread knowledge through cyberspace.Professor Lewin's videotaped physics lectures, free online on the OpenCourseWare of the Massachusetts Institute of Technology, have won him devotees across the country and beyond who stuff his e-mail in-box with praise."Through your inspiring video lectures i have managed to see just how BEAUTIFUL Physics is, both astounding and simple," a 17-year-old from India e-mailed recently.Steve Boigon, 62, a florist from San Diego, wrote, "I walk with a new spring in my step and I look at life through physics-colored eyes."Professor Lewin delivers his lectures with the panache of Julia Child bringing French cooking to amateurs and the zany theatricality of YouTube's greatest hits. He is part of a new generation of academic stars who hold forth in cyberspace on their college Web sites and even, without charge, on iTunes U, which went up in May on Apple's iTunes Store.In his lectures at ocw.mit.edu, Professor Lewin beats a student with cat fur to demonstrate electrostatics. Wearing shorts, sandals with socks and a pith helmet -- nerd safari garb -- he fires a cannon loaded with a golf ball at a stuffed monkey wearing a bulletproof vest to demonstrate the trajectories of objects in free fall.He rides a fire-extinguisher-propelled tricycle across his classroom to show how a rocket lifts off.

Hydrogen car to be Open Source

The manufacturer of a hydrogen car unveiled in London on Tuesday will make its designs available online so the cars can be built and improved locally.The Riversimple car can go 80km/hr (50mph) and travels 322km (200mi) per re-fuelling, with an efficiency equivalent to 300 miles to the gallon....The company will distribute the engineering designs to the 40 Fires foundation, a not-for-profit organisation that will make the designs "open source".The idea, they say, is to allow local manufacturing in small plants. This stands in contrast to the "economies of scale" that drive current plants to huge sizes and workforces.In addition, designs can be adjusted for local markets, using locally sourced parts or materials.The agreement will be such that if the designs are improved by a local manufacturer, those improvements will be sent back, so that what the company refers to as its "network of manufacturers" can contribute to the overall development of the product line.

Open links in new tab checkbox not working

I added a comment to the following post. https://www.instructables.com/community/Links-in-articles-should-open-a-new-tab/ Then I realized that it is a year and a half old.   And it doesn't mention the checkbox.  I am guessing the checkbox was added since then and is now not working. And that this is a new bug.  As I said in my post, I set the checkboxes to "Open in New Tab".  Then I publish and the links open in the same tab.  Then I go in (several times) recheck the checkboxes, go back and verify that they are checked and republish.  They still open in the same tab and when I go back into edit mode, they are unchecked.  Is this a bug?  Or am I doing something wrong?  If I am, I would argue that the instructions for using this checkbox have a bug. Ergo, there is a bug. Don't you hate philosopher/engineers? Grin, that's me!

designing an easy to build open source 3D printer

Hi, I'm trying to design an open source 3D printer that should be easy to build, doesn't require any 3D printed parts (all custom parts should be made out of plates) and the other parts should be standard parts (CNC) you can easily buy on ebay. I'm as well playing with the idea that you could make the custom parts out of cardboard (since they are so simple) and then print parts that are similar to reprap's, so one design would be made with 3D printed parts. It's supposed to be a low cost (300-500$) printer. I wanted to build a cheap open source 3D printer but didn't find anything I liked so I decided to design a simple printer I would like. If I'm already designing it I can as well make it open source for others. I tried to put together some concepts in SketchUp, this is how it looks so far, what do you think, tips, suggestions? the collection of the designs: http://i39.servimg.com/u/f39/14/68/63/67/design10.jpg the gallery with bigger pictures: https://imageshack.com/a/gwdz/1 or http://www.servimg.com/image_preview.php?i=177&u;=14686367

I'm not sure how many instructables readers/authors identify with the open source community, but what you guys are doing in terms of publicly documenting hardware projects is awesome and makes your perspective especially valuable.  The Open Hardware Toolchain Survey is an attempt to uncover a basic list of user/developer requirements that can be contributed to the documentation discussion and, ultimately, lead to a new generation of collaboration tools.  I would like to personally ask you to take 10-15 minutes to add your perspective and/or pass this request along to anyone you think might be interested. The compiled results of the survey will be made available and will also be used at the OSHWA's DocJam.

How could I make an open circuit diving apparatus? Answered

For a quick summer project I always wanted to scuba, Hookah Style. Hookah SCUBA diving is basically diving without the tanks and with a surface line. Well I wanted to build one of these for my friends pool. First of all I wanted to build this all myself using store bought materials. I get the concept but I want to know two things. 1. Would A fish tank Airpump supply breathable Air, now I thought of this for two reasons, it is oil-less and If it is suitable for fish than it must be suitable for humans (fish are more sensative to that kind of stuff). 2. how would I build the mask, could I just get a half face mask and add an airline (inhale through nose, exhale through mouth) or would I have to build some sort of thing that works like a gas mask? Any Input would be wonderful! EDIT: I believe I will be using a small (oil less) air compressor instead of an airpump
