Apologies in Advance

I've mentioned it before, but now is almost the time: I'm going to CERN on Monday, for most of the week. It's actually a professional development session (I'm supposed to be getting inspired to produce inspiring teaching materials), so it's not a jolly, honest. Anyhoo, bizarrely, in the birthplace of the internet*, wifi internet access is apparently quite unreliable there, so I may not be around as much as you are used to. I'll be spending the time in a days-long nerdgasm instead. (*it involved physicists being too lazy to cycle between work stations)

Advanced Search

If this already exists and I just can't find it, please inform.  Otherwise please, please provide an advanced search feature.  What apparently exists is far too primitive for a site as diverse and and at the same time special interest as Instructables. For starters I suggest the following simple and easily remembered scheme:  - single word search terms  - conjunction of terms using + to create multi-word atomic search terms  - logical connections of terms and groupings using &, | and ~  - grouping with ()  - arbitrary prefix, suffix and infix using * as the last, first or both  - escape of these search characters using \ For example (using " " for expository purposes only):   raspberry+pi -- matches the two consecutive terms "raspberry pi"   raspberry+(pi | pie) -- matches either "raspberry pi" or "raspberry pie"   (raspberry+pi) & nas -- matches if the terms "raspberry pi" and "nas" appear anywhere   (raspberry+pi) & (nas | server) -- you guess   *dog -- matches words with "dog" as the last three characters   dog* -- matches words with "dog" as the first three characters   *dog* -- matches words with the three characters "dog" anywhere in them A way, unspecified yet, to apply the query to title, summary or body of the project and some combination thereof. Further suggestions invited.  This would make the site so much more useful for finding solutions.  Implementation of the suggested scheme would occupy a good coder for about half a day.  Great project for an intern.  :-) As an advanced advanced search the use of full regular expressions would be incredible and there exist numerous public domain regex implementations (not sure about Javascript) that could be easily incorporated (wrote a complete one myself in C 30 years ago and it was surprisingly compact.)

Advanced Helmet

Advanced Helmet By: Arseny Ratnikov I want to create a helmet that looks like a sci fi helmet (mass effect, titanfall, halo, etc.) and that; **Want to make cool helmet, need help with having multiple camera feed output to multiple screens** * Protects my head (able to decrease force from impact by significant degree) * Can filter the air I breath (does not need to be super extreme filter, just filter out general junk, the better the filter the more pleased I am, but if it becomes too bulky/expensive then it is unnecessary)(Optional/Most Likely) * Has a HUD with my vitals on it. I would wear some sensors, such as HR monitor to have some cool biofeedback, maybe also include other information.(option) * Maybe even have it be a digital display where there are cameras on the front and maye back of the helmet that then are displayed on the interior screen, where I have voice commands setup for some different things. * Have the helmet be as sound proof as possible and have microphones where my ears would be, then inside the helmet speakers, so that I can modify the noise around me to be how I want it to be. I understand this would be rather difficult (at least including all of the bullets) and that it could even be a touch silly. Yet, I find this a rather intriguing pursuit and think it will help contribute to becoming a cyborg. Any tips would be greatly appreciated as I don't really know where to start for this. I can imagine a lot of the work might be done on an arduino, but I simply don't know the feasibility of modifying noises of the world around you and having the cameras on the helmet. So here's a little prioritization sheet I worked out, it is not exactly in order, and maybe you all have some suggestions on what might be more critical to design and functionality. Prioritization 1. Functionality a. Head protection a1. Padding/Inertia dampener a2. Sturdy/solid b. Control of phone through bluetooth b1. In helmet speakers b2. In helmet microphone b3. Voice control c. Control of other systems such as screens c1. Voice control of screens c2. Screen modification c3. Screen HUD and other functions (maybe GPS map, time, etc.) d. Camera view d1. Camera live to screen with little to no latency d1a. 360 degree view compressed to 180 degree screen (maybe) d2. Computer control of camera feed d2a. Visuals, different HUDs e. Sound modulation e1. Sound cancelling e2. Sound reproduction at low to no latency e3. Sound modification e3a. Changing pitch e3b. Change decibel levels e3c. Change relative level of external sounds f. The HUD f1. Display of vitals f1a. Heart rate, oxygenation, etc. (Requires some monitor) f2. Display of time and other running interests f3. Display of current location on google maps/GPS system g. Air Filtration g1. Filtration of air, relatively high quality g2. Seal on head or seal over mouth and nose or full body suit that connects to helmet h. Extra Features 2. Style a. Look good b. Look like popular sci-fi media c. Does not interfere with functionality and accents functionality How should I do this? I am planning on using some old phone screens if I can for the screen part and multiple cameras. I plan on using a raspberry computing system (might need multiple) to modulate the output from the cameras. How could I make multiple camera outputs lay onto multiple screens that looks good at three to five inches from the eyes? Also how can I make the raspberry pi control my phone and computer via voice, or at least change a screens properties? Thanks

Further Advances in Invisibility

As those of you who have been fervently following my posts for over a year know, last summer I was working on making myself invisible. While my the results of my experiment were lackluster, it appear that a man in China has nearly perfected the technique. He says his quest towards invisibility started in 2005 as a protest of the Chinese government who had shut down his art studio. You can see some of the results of his research here.

Advance Holiday Warnings

OK, so we survived A-Maya-geddon*. Unfortunately, that means I have to visit the in-laws... Actually, that's not so bad as it sounds, but Kitefamily Christmases are complicated affairs, happening in a variety of locations, with a variety of quality of internet connection. If it looks like I'm ignoring you, check the date - if it's not yet the 30th, I probably haven't seen your post yet. So, just in case, have a happy holiday season, of whatever variety you choose to celebrate, and take the best wishes of the entire Kitefamily with you into the future. In the mean time, here are two Christmas-themed projects from the archives that could be used for last-minute gifts or diversions: ear-rings, and a flying toy. *I wish I'd thought of that a few days ago!

A advanced Arduino calculator?

So I thought about a new project: make an "advanced" calculator since online there are plenty of tutorials of simple ones. I have done already the circuit and I have only some problems with the code since this is only my third project on Arduino and I don't  know programming in C. So basically: when I switch on the device it shows me a long text which I can scroll using a pair of pushbuttons(when the text can't scroll anymore a led switches on). When I push them contemporanealy the device switches to calculator. And this is the code I made (I know there are plenty of errors): #include #include long num1,num2 ; double total; char operation,button; const byte ROWS = 4; const byte COLS = 4; char keys[ROWS][COLS] = {   {'1','2','3','+'},   {'4','5','6','-'},   {'7','8','9','*'},   {'C','0','=','/'} }; byte rowPins[ROWS] = {A0,A1,A2,A3}; //connect to the row pinouts of the keypad byte colPins[COLS] = {A4,A5,0,1}; //connect to the column pinouts of the keypad Keypad customKeypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS); // === CONSTANTS AND GLOBALS === // -- PINS -- const int PIN_LCD_LED = 6;  // analog const int PIN_ERR_LED = 7;  // digital const int PIN_BUTTON1 = 8;  // digital const int PIN_BUTTON2 = 9;  // digital // -- LCD -- // PIN 12   -> RS // PIN 11   -> Enable // PINS 2-5 -> D4-7 LiquidCrystal lcd(12, 11, 2, 3, 4, 5); // number of columns in the LCD const int LCD_COLS = 16; // LCD brightness [0, 255] const int LCD_BRIGHTNESS = 128; // LCD ON or OFF int state_lcd = LOW; // start position for text int lcd_start = 0; // -- LED -- // LOW -> LED is OFF - HIGH -> LED is ON int state_led = LOW; // stores time when turned LED on unsigned long t0_led; // timeout to turn the LED off const int LED_TIMEOUT = 500; // -- text to print -- // ASSUMPTION: text always longer than LCD_COLS, if not add a check in loop const char TEXT[] = "After trying Helloworld I made this more advanced version..."; const int TEXT_LEN = (sizeof(TEXT) / sizeof(char)) - 1; const int LCD_LIMIT = TEXT_LEN - LCD_COLS; // === CONSTANTS AND GLOBALS END === // === INITIALIZATION === void setup() {   // -- SET DIGITAL PINS --   pinMode(PIN_BUTTON1, INPUT);   pinMode(PIN_BUTTON2, INPUT);   pinMode(PIN_ERR_LED, OUTPUT);   // -- SET UP LCD --   lcd.begin(16,2);   lcd.noDisplay();   digitalWrite(PIN_LCD_LED, state_lcd);   // ERROR LED is off when starting   digitalWrite(PIN_ERR_LED, state_led);   // -- read buttons --   int state_button1 = digitalRead(PIN_BUTTON1);   int state_button2 = digitalRead(PIN_BUTTON2);     // pushed button 1 -> try to scroll left or turn LED on if can't     if(HIGH == state_button1)     {       if(lcd_start > 0)       {         lcd_start--;         state_led = LOW;         digitalWrite(PIN_ERR_LED, state_led);         delay(200);       }       else       {         state_led = HIGH;         digitalWrite(PIN_ERR_LED, state_led);         t0_led = millis();       }     }     // pushed button 2 -> try to scroll right or turn LED on if can't     if(HIGH == state_button2)     {       if(lcd_start < LCD_LIMIT)       {         lcd_start++;         state_led = LOW;         digitalWrite(PIN_ERR_LED, state_led);         delay(200);       }       else       {         state_led = HIGH;         digitalWrite(PIN_ERR_LED, state_led);         t0_led = millis();       }     }     // -- print text on the LCD --     for(int i = 0; i < LCD_COLS; i++)     {       lcd.setCursor(i, 0);       lcd.print(TEXT[lcd_start + i]);     }     // ERROR LED is ON     if(HIGH == state_led)     {       unsigned long td = millis() - t0_led;       // LED has been ON for more than LED_TIMEOUT ms. -> turn it OFF       if(td > LED_TIMEOUT)       {         state_led = LOW;         digitalWrite(PIN_ERR_LED, state_led);       }     }   }   // normally 20FPS   // === INITIALIZATION END === // === MAIN LOOP === void loop() {   // == LCD STILL OFF ==   if(HIGH == state_lcd)   {     // pushing both buttons -> turn LCD on     int state_button1 = digitalRead(PIN_BUTTON1);     int state_button2 = digitalRead(PIN_BUTTON2);         if(HIGH == state_button1 && HIGH == state_button2)     {       analogWrite(PIN_LCD_LED, LCD_BRIGHTNESS);       lcd.display();       state_lcd = HIGH;       delay(250);     }   }     else  // == LCD ON ==   {     // Loops are convenient for reading key press from keypad     while(1) // First loop.

Should we have &quot;Advanced Searching&quot; on Instructables?

I'm posting this topic to bring forth the idea of having advanced search capabilities on Instuctables. If anyone has visited a member who has amassed a huge number of instructables, you'll notice that using the "next" button is rather inefficient for searching. If you don't know what I mean, go to Kitemans page and search for the first instructable he wrote.  There are also times where you are looking for a specific instructable written by a member and would therefore need a method to do so, especially when some members have written over 100 instructables. There may be a specific forum topic, group, guide, or question/answer that you're looking for, and again, you'd need a way to search these only. I'm sure I'm missing a few examples, so feel free to throw in your 2 cents regarding advanced searching on Instructables, and maybe the staff might implement it for us.  Thanks, canucksgirl

Tricky batch stuff...?

This isn't exactly a conventional question, but it's a question nonetheless.  The thing is, I'm thinking of starting a forum for all the tricky techniques and methods with batch (it wouldn't be a great instructable as it would require a lot of previous knowledge). So, I'd basically just have an index with all these different segments of how to do tricky stuff (such as advanced techniques for piping and other random stuff). The only problem is that I don't know what to make it on, so I'm trying to target people who've read all the instructables and are still missing that extra bit of information. Now, you could say something like "do whatever you think is hard", but the thing is I work better when it's at the request of someone else (basically I like to help people, and I'm abusing that natural urge). So, if you're experienced in batch but are curious about anything (perhaps how to ignore every rule in the book and put 50 nested for loops within your script), please post it below. Thank you. --EDIT-- I've started rewriting my batch tutorial, so most of the stuff you comment will go into that... somewhere.

When driving, I want it flat against the ceiling and to sleep I want it to fold down between the dash and the back of the seats - a cutout for the top if the steering wheel is fine.This involves moving it through a very specific path through space with a mechanism along the same lines as the folding rotation of a sofa bed. I would like to know what joints are available so that I can figure out the correct combination for the required movement but I can't even find the names of them. "Complex hinges" doesn't seem to bring up anything useful. Any suggestions?Thanks,Mike.

Omniversity : Advanced Arduino Course in Manchester

We're launching the Omniversity, housed at the Manchester Digital Laboratory. The MadLab has been one of the country's most successful hack and creative digital culture spaces, attracting thousands of visitors to the region and bringing in national and international talent to lead free workshops and events. Every evening is double-booked with free community-driven events around open platforms and professional development. Building off the back of this success, and the huge network we've built, we're offering the Omniversity - an expert-lead series of training programmes, designed to be affordable and lead by industry veterans and in-the-trenches professionals, rather than full-time tutors. We'll be teaching people platforms from the near-future, without the cost overheads that more formalised training providers impose. This brings us nicely to the course of the Internet of Things... The Arduino boards have become the de facto choice for physical computing projects and, with the addition of an Ethernet shield, make an excellent platform on which to explore the Internet of Things. Want your letterbox to email you whenever the postman has been? Need a clock to show you where your loved ones are? Or a glowing multi-coloured ambient orb to show your energy usage? This course will get you started on the road to realising your own Internet-connected projects. The course is on Friday, 25th February 2011 and costs £132.00 - included in this is an Ethernet shield, selection of components, wires and cables. All you'll need on the day is your laptop and and Arduino Uno or Duemilanove. Lunch and hardcopy course materials are also included. The course is lead by Adrian McEwan, creator of the bubblino.com family. To find out more & book onto the course please see here. Hope to see you soon! MadLab

How do I rip sounds from older games? Answered

I'm attempting to create a content pack for a Minecraft mod, and need old gun sounds. Anyway, I remembered an older game (not DOS era) game, Oregon Trail, and thought I could rip the sounds out of it, since it had some nice gun sounds from the hunting sections. Anyway, usually this wouldn't be a problem, but that's only if the sound files are either .wav or .raw (which I can expand using audacity), but ... well... as you can see, I don't have anything to work with here. If someone can point me to the proper file, I can probably extract the sounds from there (I have another windows PC I can use if necessary)  Note that the folder labeled "CD" is a direct copy of the game CD.

GameBoy Advance overly saturated screen... How to fix? Answered

I got a GameBoy Advance a few years back, the Nintendo DS of last decade. It worked great for about a year and then (I think I may have dropped it) it started displaying the colors on the screen way too brightly! Nothing else was effected, but the screen looks as though it doesn't know what "dark" means. All of the games I try to play are way too lightly-colored, to the point that I can't see any details at all. As you can see, I try to play Frogger's Adventures: Temple of the Frog, but I can barely see where I'm going because the screen is too saturated. Oh, and another thing: After the screen started doing this, I dropped it once more, and it switched back to normal for a time, but then after 30 seconds, it flipped to the higher saturation again. This would lead me to thinking that something is broken inside... Is there anyone out there who knows of this problem, and perhaps, knows how to fix it? Thanks, Win Guy

RF Development Kit-Advanced, but could be a lot of fun

Micrel SemiconductorEbay{{{ I have noticed that some people are concerned that due to surface mount technology you can't make electronic stuff anymore. It is not true. A search will quickly find forums discussing how homebuilt electronics experimenters are getting around this. I have a nifty RF development kit for sale on ebay. See ebay link below. These development kits are used by new product developers to quickly get their RF prototypes up and running to develop software, hardware and firmware without the steep learning curve associated with starting development with discrete components. These boards allow you to build custom devices that can comunicate with each other up to a mile apart. Although this is not quite ham worthy distance someone might be able to have some fun with the kit. I have just one, but more (and the actual rf chip) could be acquired through Micrel Semiconductors. Anyway, I have this listed as an industrial item, so I am not sure the right people will see the ad. For those interested in playing with current technology RF.}}}

Why the Advancements in Knex Gun Technology Have Stopped

     I, as many other members of the online k’nex gun making community may have, noticed that particular aspects of k’nex weaponry have stopped evolving. The very best k’nex guns of today are guns such as the TR18, the ZKAR, and other far shooting, rapid-fire guns. Now that’s fine, but other aspects of guns have stopped evolving, and innovation has been halted. This is ironic considering many of our communities best builders belong to forum with innovation in its name, and we have so many builders advocating innovation in everything they say. The reason for this lack of new ideas is that the members of our community are not sharing their ideas with each other and encouraging others to build off them. I will explain this theory in my following paragraph.       Out of everything that has been made in the world, it was all developed because people want to top each other and people build off of each other’s ideas and accomplishments. Unfortunately, this is not happening in the k’nex online community. The biggest example is the everlasting KI/Instructables rift that has separated k’nex builders since even before the creation of Knex Innovation. No knexer even thinks of sharing the guns they’re developing with a knexer of the opposing site. Even bigger than that though, is the reluctance to share ideas with anyone. How many times have you seen people anywhere saying that they are building a new gun, but they won’t share pictures because they’re scared of people copying them? This is what hampers all creativity and innovation. If people cannot build off the ideas of other people, we will never advance. Sure we’ve gotten this far off people’s successful ideas that they’ve posted, but imagine how far we could be if everyone shared their failures as well. We could fix the guns that others could not get to work. Imagine all the possibilities if every single mech anyone ever tried to make was open to the public to use and improve on. Now this happens not only in Instructables where everyone goes crazy if they think someone even slightly copied their gun, and never shares their ideas with others except for those rare collaborations. This also happens at KI where there is a whole “secret forum” that the most experienced builders and contest winners get to see, where they post their ideas where all the other builders can’t see them. This selfishness needs to end so that we can continue innovating and creating new guns and ideas.

23 stage no-capacitor full auto coilgun

  *********I have updated my design since posting this topic. The video is the more current design than what is written below.**********    I came to the conclusion that using capacitors to provide the power for a coil gun is a stupid idea. A bold statement I know. The reason is that they are big and heavy, take time to charge, and need charging circuits. Also, the sharp rise in current that comes from capacitors is bad unless you are making an induction style coilgun, because the induced currents will hurt efficiency.    If coil guns are ever going to be a practical hand held weapon it will need to be lighter, simpler / less delicate, and more powerful than what you will find on the internet if you look up coil guns. A rate of fire that is competitive with conventional guns will also be needed if a coil gun will be used for anything other than target shooting or maybe hobby hunting. So I designed a coilgun to meet these requirements. Visit my website for a full explanation of the design: http://www.ourbadscience.com/#!em-guns/cwjy     I realized that a coilgun would not be a practical infantry weapon until batteries are more advanced anyway, so that just adds to the list of why capacitors are out. It will be powered directly off of the batteries, and have many coil stages. This allows a very high rate of fire. To get that rate of fire with capacitors you would need several capacitor banks charging at offset times, so after each bank fires another is just finished charging. That would be terribly bulky.    The lower voltage from the batteries will give comparatively slow current rise in the coils which normally would make the coil timing weird. I plan to use an unconventional coil timing though. All the coils will be activated at once, and the coils behind the projectile will be shut off as it passes them. This will have several advantages: -The coils will only be powering up for a split second at the beginning. Most coils will already be at full power when the projectile gets to them (that is not the case in most coil guns). -Induced current will not be any issue. -Since the coils will all act as one coil, the projectile will be drawn toward the center of all the coils that are on. Timing of the shut off of the coils will not need to be perfect.    This will be a pre-tuned passively timed system. I want to use a small adjustable electronic timer for the switch-off timing. This will require some work in the initial adjustment of the timing, but even actively switched coil guns (with optical sensors or something) require that. the advantage of a passive system over an active system is cost and simplicity, and you can pack the coils tighter on the barrel if you are not putting a sensor between each stage. That matters with 23 stages! As I said check out my website to see more details and pictures for this and other projects: http://www.ourbadscience.com/#!em-guns/cwjy

How do you make a Gameboy Advance to Gamecube wire?

I have been looking around for wires, and most places, I check don't have it, or Ebay, and Amazon is too expensive for what I am willing to pay.  I have GBA connector wires, and GCN extender cords.  Can I use these to "make" a gameboy advance to gamecube wire, and how would I go about doing this. -On a side note, could I also make an edit to supply it to a NDS?

12-year-old designs advanced 3D solar cell

From Slashdot:12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. "Current solar cells are flat and can only absorb visible light" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency."Much about his young man is eerily similar to many participants here on Instuctables...SlashdotBeaverton Valley Times storyKatu.com story

Anyone have a way to make a gameboy ds/advance case without duct tape?

I'm looking for a way to make a smallish, easily carried case for about 18 Nintendo DS games and maybe 6-10 Advance games. I don't want to use duct tape, and the cloth and plastic roll up Instructable isn't exactly what I'm looking for.

Can I use a RC TOY transmitter to control an advanced receiver?

I have one of those micro rc cars.The car died and I'm experimenting with its parts. I was wondering if it's possible for a simple Tx ,like this one, to control an advanced Rx connected with a Brushless ESC. By simple I mean single speed(forward without ESC) and with advanced those used for example in rc helis(advanced tech,many ch). I am definitely talking about the same Quarz crystal controlled frequency. Thanks you.

VB 2008 AxWindowsMediaPlayer Control Help?

Hey everyone. If your an advanced user in Visual Basics 2008 Express Edition, I could use some help. Right now, I'm working on a video presentation program for my Home Theater PC. I'm planning on hooking up my computer to my T.V and using it as a secondary screen. I will then run an HDMI cable to my monitor, and use that as my main screen. My mouse and keyboard are wireless so it won't pose a problem. But, anyways. I'm getting off topic... I made a form with a bunch of controls on it. It has 10 textboxes for video URLs and 5 textboxes for audio URL. It has 2 AxWindowsMediaPlayers on it. One for music, the other for video. The main one (Bigger one) will be used for video, and it will also act as a control window. So, when I click play one one the textboxes, it will open the file up one both Media Players and will begin to play. I know the coding for that, its just I need to know how to control the 3rd Media Player, on a different form. So basically, the 3rd Media Player would copy the 1st media player. Any help would be much appreciated.  Thanks.

Any suggestions for colleges to help me advance a career in film/editing?

This is more about my decisions later down the road in life than it is my current interest in editing and filming.  I've been doing some research in colleges that will help me get a major in film and video production and I've narrowed my choices to a few.  I'm not going to list them here, since I want some community input on this and I don't want the response to be biased based on my list.  What colleges do you think will give me the best, most hands-on, most fun education in this subject, as well as be the best for when it comes to getting a job in the industry?  I can do as much research on this as I need to, but what I think matters to me the most at this point is other people's opinions.  I'm more likely to try or consider something if friends recommend it, and you guys are always a thoughtful community.  Thanks in advance!
