Okay, here they are! The results for the instructables survey!Unfortunately, there was a small response, with only16 people replying.Anyway, here are some interesting things:75% of people who replied are in the USA75% use firefox to access instructables, the rest are equally usedMost people use windows XP, followed by Vista and then OSX.You can download the raw data (CSV) below (There may be a problem opening this with excel, as some of the results appear as dates).PS: What are your suggestions for making more people reply, and I was thinking, should I do this triannually?

. Judging by the number of ppl that have signed on to this group, it looks like there is enough interest to see about really doing something. . In no particular order or importance: 1) Need name for org. Do we need Pres/VP/&c? 2) Who in group can give out which "awards"? More than one person? 3) I don't think we need patches - many recipients would see them as awards. I think we should just give as comments to iBles/posts. 4) Need to come up with some guidelines as to what is unsafe enough to deserve a graphic/comment. May want to have a series of small graphics (similar to patches?) such as "High Voltage", "No Safety Procedures/Warnings", &c 5) I don't think we want to take this too seriously and become pedantic about what is posted, but we want to make sure that no one attempts a dangerous iBle without the proper warnings.

The rise and rise and eventual lawsuit over Scrabulous has shown that people love their Scrabble. Now you can even eat it with this decidedly unofficial Scrabble chocolate bar. They seem to be out of stock, but if they do come back, try and get them before Hasbro's lawyers do. link

Officially, we support Firefox, IE6, and IE7. Unofficially, everyone here uses the site on a daily basis with Firefox. If there are bugs specific to another browser, we often won't notice them right away. This is particularly true of Safari, where lots of things are known not to work. So, if you are having trouble with something (uploading images, operations within your library), try doing the same thing with Firefox and confirm that it's not a browser specific bug. Thanks for your patience as we aim to make everything work perfectly all the time!

Has anyone ever experienced the fourth dimension. Sure this is a topic for science fiction novels, new age conspiracy theories and the new Indiana Jones movie. But dimensions past our own experience are having a big impact in theoretical physics. Flat Land and it's unofficial sequel Flatterland are good books to get a mathematical yet whimsical look into alternative dimensions. The Tesseract from A Wrinkle in Time was a hyper cube as well.So we go from 0D (a point) to 1D (a line) to 2D (planes) to 3D (solid objects) and then what happens when you pull that plane into an unseen dimension? Well, use your imagination and watch this video: 6d-Hypercube from Tobby Lang on Vimeo.Why Bother With 4D?Yours_BG*(Corrected, thanks n8mansays)

I was cleaning out my Inbox a few minutes ago and came across an exchange from June of last year saying one of my Instructables was to be included in the Ultimate Unofficial Guide to Minecraft Strategies and asking what name I wanted to appear in the book. I replied and got confirmation of my choice but I haven't heard anything since. I recently received my Author copy for How to Fix Absolutely Anything which made me wonder if that was being done for this Minecraft book too. It was published more recently so maybe I'm just jumping the gun but I wanted to make sure I hadn't missed the boat on this. If free author copies aren't going to be a thing in the future or for every book is it at least possible to find out which books contain your Instructables?

Having finished my rifle and finding myself with nothing to do ( Don't worry, it will still be posted this week ), I thought I'd finally have a go at side-arms. So I built the TDS2, and hated it ( I'm going to get bashed for that, I know it ). I decided to have a look at some others like Oompa-Loompa's unofficial side-arm, and the one Bakenbitz posted a picture of on KI some time ago. Afterwards, I came up with this. This side-arm is powerful because the magazine is at the front and the trigger is at the very back. It's also kept reasonably small because the magazine is inside the handle.It fires grey connectors. It's a bit clumsy, but it is only a first version. I can probably make it a bit smaller and more user friendly if I remake it. Tell me what you think, and as always, constructive criticism is more then welcome

The first annual (hopefully) Instructables survey. EDIT: The Results are in! (link)Why a survey, you might ask? Well I thought it would be interesting to see a couple of things. Average number of Instructables people make, Most popular OS etc.Anyway, give it a whirl and we'll see what people like best.Oh, and once you have finished the survey, could you please pass on the link to this forum topic to anyone who is on instructables that might be interested and would not come across this themselves.Fineprint: This is not an official survey and as such the team at instructables take no responsibility for it. The survey will only collect the answers you give, your username, email and other personal data remain private unless you put it into one of the boxes. IP addresses may be recorded. If this violates some kind of instructables ToS or anything, can a staff member please PM me and I will remove it. Otherwise, the results should pop up in the community blog in a week or two.EDIT The results will be released Sunday, 19 April 2009, 00:00:00 UTC. Click here for different time zones

First posted here. Last Friday, I drove up to Maryland to see UMD's Gamera II human-powered quadrotor. They are currently pursuing the Sikorsky Prize, established in 1980. Here's the team testing a new control system. http://youtu.be/3B2of4V35d0 (sorry, the embed function isn't working) During this test, Gamera II flew for approximately 65 seconds, unofficially tying the endurance record that the team previously set. This flight time, plus the ability to remain within a specific boundary, satisfies two requirements of the Sikorsky Prize. Because the rotors are so close to the ground, the helicopter is benefiting from a cushioning effect of the air between the rotor blades and the ground. This effect will diminish exponentially when the team attempts sustained flight at the required 3 meters. The helicopter transfers the pilot's pedal power by unspooling cable from pulleys, mounted on the shafts of each of the four rotors. Flight time is limited by the pilot's stamina and the amount of cable stored in each pulley. The rotors are constructed of carbon fiber, balsa, and foam, and are covered in a plastic film. All in all, it was a cool experience. I've never seen so much carbon fiber in my life! I look forward to seeing the team win the Prize.

Hello, I am in search of companies that offer internships to high school graduates going into college as a way to gain experience. The problem is that companies I want to intern for all want (Idaho Power, Union Pacific Railroad) college experience and previous college education in that field. I am primarily interested in the industry side of things, because I want to see how things work and experience them myself. The industry is considered “dangerous” so therefore I have not been able to find any companies willing to offer internships to high school graduates. I really don’t care about pay, because I am only interested in education as of right now and this would be very valuable. I would prefer local companies, but I would be willing to go out of state. What I really want to know is: How can I convince companies to let me shadow an employee or be an unofficial intern? Do you need documentation from companies that you interned with them when writing college resumes? What sort of companies would be interesting (Idaho Power, Union Pacific, Norco, etc.)? Anything else you may be able to suggest. Thanks!

UK-built solar-powered plane has set an unofficial world endurance record for a flight by an unmanned aircraft.The Zephyr-6, as it is known, stayed aloft for more than three days, running through the night on batteries it had recharged in sunlight.The flight was a demonstration for the US military, which is looking for new types of technology to support its troops on the ground.Craft like Zephyr might make ideal platforms for reconnaissance.They could also be used to relay battlefield communications.Chris Kelleher, from UK defence and research firm QinetiQ, said Unmanned Aerial Vehicles (UAVs) offer advantages over traditional aircraft and even satellites."The principal advantage is persistence - that you would be there all the time," he told BBC News. "A satellite goes over the same part of the Earth twice a day - and one of those is at night - so it's only really getting a snapshot of activity. Zephyr would be watching all day." The latest flight was conducted at the US Army's Yuma Proving Ground in Arizona.The Zephyr flew non-stop for 82 hours, 37 minutes.That time beats the current official world record for unmanned flight set by the US robot plane Global Hawk - of 30 hours, 24 minutes - and even Zephyr's own previous best of 54 hours achieved last year.However, the Yuma mark remains "unofficial" because QinetiQ did not involve the FAI (Federation Aeronautique Internationale), the world air sports federation, which sanctions all record attempts.The US Department of Defense funded the demonstration flight under its Joint Capability Technology Demonstration (JCTD) programme. The 30kg Zephyr was guided by remote control to an operating altitude in excess of 18km (60,000ft), and then flown on autopilot and via satellite communication.It tested a communications payload weighing approximately 2kg.At first sight, the propeller-driven Zephyr looks to be just another model aircraft, and it is even launched by hand. But this "pilotless" vehicle with its 18-metre wingspan incorporates world-leading technologies.Its structure uses ultra-lightweight carbon-fibre material; and the plane flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper. These are glued over the aircraft's wings.To get through the night, the propellers are powered from lithium-sulphur batteries which are topped up during the day."A lot of effort has gone into power storage and light-weighting the systems," explained Mr Kelleher. "Lithium sulphur is more than double the energy density of the best alternative technology which is lithium polymer batteries. The engineers from the Farnborough-based company are now collaborating with the American aerospace giant Boeing on a defence project codenamed Vulture.This would see the biggest plane in history take to the sky, powered by the sun and capable of carrying a 450-kilo (1,000lb) payload.US commanders say the design must be able to maintain its position over a particular spot on the Earth's surface uninterrupted for five years. QinetiQ is the public company that used to be the British Government's military research department, before they privatised it.BBC articleQinetiQ's page on Zephyr

CELEBRATIONS have just finished at the Brookhaven National Laboratory in Upton, New York, for the 50th anniversary of a milestone that had nothing to do with basic physics research. In October 1958, nuclear physicist William Higinbotham created one of the world's first video games, called Tennis for Two.Officially, his goal was to liven up displays at the lab's annual visitors' day, and in that he succeeded. Hundreds of people lined up to bat a glowing spot back and forth across the video screen of a common or garden laboratory oscilloscope.Unofficially, Feedback suspects he was really just goofing off on a slow day, or waiting around with nothing to do when the lab's particle accelerator was broken, being maintained or otherwise failing to deliver the goods. Higinbotham himself said the idea came to him while reading the manual for an early computer which could plot the course of a missile or a bouncing ball on an oscilloscope screen. He then designed suitable circuits and control boxes - Stone Age versions of today's joysticks - so that two players could bat an electronic ball to each other across the screen.The game was adapted for a larger screen, but eventually forgotten until 1982, when Creative Computing magazine heard about it and thought it might be the first video game. With the invention far enough behind for him not to worry about accounting for time wasted on the government payroll, Higinbotham claimed credit for Tennis for Two.Such primitive video games are old hat now, but hundreds of physicists including our own Kelseymh are still waiting for the completion of repairs to the Large Hadron Collider at CERN. What might they be inventing this time, while sitting around twiddling their thumbs?New Scientist Article.Tennis For Two Simulator (untried by your correspondent)

Instructables' first artist in residence to start at Pier 9.I lucked out and happened to be that person. I also lucked out and happened to be at Pier 9 for about nine months. I feel like I've had one of the strangest residencies at Instructables. Noah was willing to be flexible enough with me to allow me to still work full time while I was there. It only allowed me my free time to work on projects at P9. I found myself there early in the mornings, late into the evenings, and consistently all day on the weekends. I've seen the sun rise at P9. I've seen the sun set at P9. I've been a lone person at P9 surrounded by millions of dollars of incredible machines. Machines that I have been dreaming about having access to for years. Free range of what I could do. Creativity overload. It becomes overwhelming at times. Some days were spent with anxiety over doing something that you hope is impressive. It can make it an intimidating place to start at. Somehow, I found myself in a building filled with some of the most competent, experienced, and creative people I have ever met. Ultimately, my biggest regret is not having enough time to spend more of my time there. The conversations you have at Pier 9 are incredible, aided with an amazing view of the San Francisco Bay and free coffee made by a robot. “What are you making?” I think this is the unofficial slogan of Pier 9 because that is the first thing someone will ask when you meet. Your response is always greeted with genuine enthusiasm. That's the culture. You are given the tools and resources to create anything. The thing that you create is welcomed with high regards. Positivity flows in everything. I am so humbled to be able to be part of what is happening at Pier 9. I think everyone agrees that something amazing is happening there. I am thankful to everyone who helped make it happen. To Noah, Vanessa, Randy, Amanda, Audrey, Gabe, Dan, Sean, J, and everyone else. Thank you. It is you that makes Pier 9 the special place that it is. The machines are only an added bonus. High fives all around.

Well, I finally got to a Maker Faire (I really was afraid I was going to get old before it happened and I wouldn't be able to make it - ( :-P Kiteman). I am still a bit dizzy, some from malnutrition (food vendors did not know what a credit nor debit card was, and I rarely carry much cash anymore), some from all the STUFF that was there to see. I declined an invitation to ride on the JET powered merry go round (or whatever it was called) that occasionally would make talking at the Instructable's booth IMPOSSIBLE. Of course, one of my favorite booths (no, I didn't get a picture of it) was a fellow that had like 20-30 old (very old) assembled Heath kits (mostly radio receiver/x-mitters) and of course the Maker tent. I don't think it is visible in any of the pictures, but I nearly seared my head off from sunlight exposure, dispite having a UV sensor on me to tell me when to get OUT of the sunlight. The most fun I had, however; honestly was meeting different members of the "gang" :-) Eric, and Cristy, Tetranitrite, Muffinator, Randy, CaitinsDad and a few others whose names escape me at the moment (hey, I am lucky I could remember those four, not because they aren't memorable, but because I have such a hard time remembering names). I even unofficially sat in at the booth for a bit, while Randy went "exploring" (I think he went into the Science Center)......oddly enough, I got about 28 people interested enough in his book to take a sticker with the URL on it :-) A real breakthrough for someone that has difficulties talking to strangers. I only got about 6 hours of sleep last night....mostly because I was still vibrating a bit when I got home. My wife was upset with me when I got home because I had yelled at her on the phone when she called while I was in the middle of he.....I mean Queens, trying to dodge taxi drivers. I had told here I would call when I arrived......and getting back safely didn't seem to make up for that little indiscretion....oh well. Anyways, here are the pictures I took....sorry they aren't more in number. Also, I smudged the faces of those I did not know......mostly because I am paranoid. :-)

On July 13, 2014, the unofficial yet famous K'nex war will take place in Freemont Ohio and luckily this year I coming back a veteran. With all the experience and advice I got from last years war I will be a stronger competitor this year, with more powerful and sturdy knex guns. With all the fun and preparation involved in getting ready for a knex war it made me think of all the iblers who don't get to come down to Ohio for the war, so I decided to try one of my ibler's war guns at the knex war. I ended up building the Red Book of Westmarch's R5 Defiance, A bolt action K'nex gun specificly designed for K'nex wars, and while he admitted he hadn't tried it at an official war he had tested it rigorously so he knew it war reliable. My stock version worked really well, it hit the range that Red had showed and it was pretty reliable. As you can easily tell by my final product, I changed practically everything about the gun. Why? Why would I do that if I was happy with it? Well there's a small difference in being happy with something and being confident with something. While the R5 was very reliable, I had trigger issues and a little chambering issue. That also being said I also have an engineering saying that goes building something is easy mindless work, making something your own, that takes skills. So I made my R5 my own and changed everything but the magazine and general body. I added: a new trigger mechanism that increased pin draw ( the stock pin draw was fine too), magazine lock ( I have a vendetta against friction in K'nex guns.. ), Upper chambering mechanism (because it makes the chambering smoother in my opinion), and a barrel (which prevents yellow rods from tumbling end over end). My modifications only increased the reliability and the overall functionality of the gun. I would definitely recommend building the R5 Defiance because it's a great gun and it'll definitely help you in a knex war. Like any gun though, try it out and make it your own before using it in battle! Anyway thanks for reading and if you have any questions I'll be around. JonnyBGood (also if your wandering why I didn't break this up into paragraphs, instructibles doesn't let me use the return key for some reason. Sorry for the huge paragraph of rambling!)

In hopes of seeing more paper airplanes and innovative designers on Instructables.com, I have decided to host a third mini-contest. My goal is to stimulate the paper airplane channel and encourage more paper airplane builders to post their innovative designs. For this contest, the specification is for a stunt plane. Requirements: 1. Aircraft Requirements: • Ability to perform a loop, wingover and/or a Cuban eight • Durability to fly at least 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 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)" • This sentence and link must be displayed on your entry's intro page: “This instructable is an entry in Paper Airplane Contest 3 (https://www.instructables.com/community/Paper-Airplane-Contest-3-Open/).” 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 receive a 3 month Pro membership. 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). *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 Monday, March 14, 2011 and ends Friday, April 8, 2011. Entries must be published before Friday, April 8, 2011. From April 8 to April 11, I will be judging all entries.

Dear Community, In the late 80s and early 90s, the whole Teddy Ruxpin craze took off, and there were many spin-offs on this. The basic idea was that the toy had a cassette player where one channel was directed to an audio circuit in the usual way, and the other channel had animation synchronization code directed to some sort of receiving circuit which controlled motors to make the mouth and eyes move so it would appear to be telling a story or singing a song. My favorite instance of this (which I had as a child), is the Ideal Big Bird Storymagic based on the famous Sesame Street character. There were so-called "satellite toys", Cookie Monster and Oscar which connected to Big Bird via a special patch cord, and they talked along and helped Big Bird tell the story. I never had those though. Different fans tell me that the animation sync code is Pulse-position modulation, the same code used over radio waves to guide remote controlled cars and helicopters. I'm not sure if this is true or not. I've looked at it in a waveform editor, and there appears to be some amplitude modulation going on here too. (Please see below). The highlighted (white) section is the span of two words. The right (lower) channel shows the voice speaking these two words, and the left (upper) channel shows what happens to the code (which really sounds like a fax machine) as he moves his jaw down, up, and down again in time with the words. Is this PPM, and if not, what is it? Now that I'm in my mid 20s, and I work with young children, I found one of these Ideal Big Birds on Ebay in great working order. I'm wondering if it's possible to try to re-create what the manufacturers used to create this sync code in the first place. Sesame Street created many nice "regular" story / music tapes with Big Bird as the central character. I thought it might be cool to take some of these (especially the Follow That Bird soundtrack) and add the sync to make my own sort of unofficial storymagic tape (just for fun, and for my students, not to sel or share, as this would be a copyright issue). I'm wondering if some sort of 1KHz oscillator-like device could be built that has levers of some kind, which could be routed through a DAW or a mixer, which would allow one to perform along with a program, and place the appropriate modulation envelopes into the stream of PPM to place the movements? I think there are at least two kinds of modulation in the code; that for the beak, and for the eyes. There must be other kinds of modulation for Cookie Monster and for Oscar. If something like this seems practical and feasible, I'd enjoy learning about it, just for the fun of it. If it is possible, I am also wondering how or where I could have it built, and for what sort of budget, as I am far better with my ears than with the soldering iron. I have tried and tried, to no avail, to find someone in the “talking toys” community who knows how this was originally created. Let me know if you'd like me to send you a clip of the audio file. Here's a link to someone else's on Youtube so that you can see what I'm talking about. Thank you so much for taking the time to read all of this senseless ramble!! http://www.youtube.com/watch?v=xxCnmao8FAs Thanks a ton for any insights that you have!!! I apologize in advance for the inherent nutty-ness of this post! ;) Sincerely, Jessica

Hello everybody ! I'm currently into a really cool project which gives me quite hard times. To begin, I'm a big noob in electronics, but I'm decent in programming. So i'm able to understand, learn or correct myself easily when it's about code, but I'm really in the dark for everything concerning electronics despite the fact that I read so much about it recently... My projet ------------ My goal is to make my own MIDI drum kit. Not a new idea, but the difference is that I want to use lot of pads. I bought some WII, XBOX and PS drum kits that I disassembled to get just de pads. Then I bought an Arduino Uno, not a mega because I'm a beginner and I can totally start with a small amount of pads, also I wanted the perfect solution in terms of compatibility etc. STEP ONE : 1 pad -------------------- So, I first made a prototype with 1 pad, which was very easy to do, since there is billion of officials and unofficials tutorials about how to connect a piezo to the Arduino. So basically, on my breadboard its like that (except im on A0 not A2) : http://learning.codasign.com/images/1/1e/Piezo_arduino.png So I connected my pad to the Arduino with a 1 Mohm resistor in parallel and I made a program which function very very well. You can read it the : http://codeshare.io/VzUGn The only challenge here was to set proper threshold and delay so the signal is clean when I hit the pad with a drumstick, to integrate the MIDI library and finally to find a software that makes the informations i send available in any of my favourites music softwares (Ableton Live, Maschine, ...), this software is Hairless Serial to MIDI, btw. STEP TWO : X pads --------------------------- It's when I'm getting troubles. At first I believed that all I needed to do was to reproduce the same schematic but "duplicate it" x times. So I tried with 4 pads. I used the same strategy on my breadboard : each pad is connected in parallel with a 1 M ohm resistor, but all are connected to ground. You can see it there : http://oi57.tinypic.com/aymsli.jpg The code, take the old one, but just loop on the 4 pins : http://codeshare.io/8Tb6z So here are the 2 issues : - The pad on the left is OK, like with my 1st program, the second one is still ok, the third one I have to hit a bit hard, the fourth one I have to hit VERY hard. - When I hit a pad, it seems it send electricity in others pins, I say that because when i connect the Arduino to a music software, hiting a pad = having multiples notes at the same time. For the hitting force issue, I'vre tried to play with resistances, puting higher or lower values and I got totally lost with that : nothing seemed to be better. About that "leaking" issue, I thought it could be useful to put some diodes, as i heard diodes are usefull when you want to make the current going in one way only, but when i watch some others schematics, i see no diodes and only 1 Mohms resistors everywhere, so I really don't know what is wrong and what to do. Here is the MIDI xylophone someone made and posted on instructables : https://cdn.instructables.com/FB6/VMRG/H4AGICO1/FB6VMRGH4AGICO1.LARGE.jpg I have no idea why this is working and why there is ground directly linked to these analog pins, and many other things i cannot understand. Any help would be really appreciated ! :)
