Help Navigating

Hello, Its been a long time since I've been  on here and the site has changed too... I can't seem to find a section for Knex guns.  Before the website changed I was able to search, "Knex Gun" and then filter the subjects. I can't seem to find the filter when I search. Could anybody help?

site navigation

Do you think that the site could be easier to navigate? i think that if you could choose how many items were listed per page e.g. instead of 20 per page, you could have 100 or more. it would make it easier because you would'nt have to click next page as many times. another thing to make the site easier to navigate would be if the names of the 'ibles, questions ect were listed in each category in alphebatical order, so that you could easily find an instructable by name.

Navigation problem on iPad

 Drop down menus in the navigation section of your page don't seem to function on iPad running OS 6. For instance, if you click on "explore" and then  click on the drop down menu "everything,"  you can't access any of the items in this menu; you can only pull up the picture below the menu. I've tried this with the Safari and Chrome browsers. This has been happening for at least the last two months and is keeping me from using your site!

Site Navigation and Search

Hello everyone!  I'm having some trouble with navigating / searching the site.  When I am browsing and I select most popular, it doesn't seem to sort in particular order. When I sort by views, it shows them in descending order, but when using most popular its a hodgepodge of results.  Also, is there anyway to search the site by materials used? It would be awesome if I could say I've got these parts / pieces, what could I make with them?  Thanks! Tim

Enhance navigation for search results

UPDATE: Kiteman points out in the comments that easier to use navigation as described below is available if you first do a search and then click the Graphical Search link on the search results page. I hereby modify my suggestion to "Make graphical search the default, or adopt the graphical search navigation for the default search results." ================ When I search the site and get multiple pages of hits, the only navigation option is a row of small linked numbers at the bottom of the page, like so: 1  2  3  4  5  6  7  8  9  10 It takes an unnecessary amount of dexterity to navigate to the next number and click it to move to the next page of results. Two suggestions: 1) Increase the font size of the linked numbers so they provide a bigger target area for my mouse pointer. 2) Add a "Previous" link to the left of the 1 and a "Next" link to the right of the 10, to provide big, juicy targets for the most common navigation needs.

Navigating large-response topics

As a participant in AngryRedHead's Photo challenge, I've noticed that, as the thread gets longer, navigating it to find my past comments and replies is getting... odd. Using the next and previous buttons seems mixed up.  Sometimes you don't get a new set of comments, sometimes you get a few extra comments in between the ones you already saw, sometimes nothing happens. Similar things happen on other topics with large numbers of responses. (Running XP and up-to-date FireFox)

I like the changes to the site navigation

I haven't seen it mentioned yet so I thought I might as well be the first. I think the navigation has changed for the better over the past few days: the forums are easier to find, and the top bar looks fresh and clean. I don't really understand what the things stated as 'Featured' are, though. Most of them are 'channels'... will they be rotated regularly to show off different aspects of the site? There's a different set of 'Featured' things at the bottom... the purpose of this is a bit vague. But yes, I like the navigation aspect, I think it's easier to find things now. Thumbs up to the designer(s).

Vibromotors and GPS turn by turn navigation

Hello, for one of my university courses I have to develop a prototype that give turn by turn signals to a person by means of vibromotors. First I would like to say that my background is mechanical and I have no idea whatsoever of electronics or software. My full Idea (Don't know if feasable) is to use the turn by turn information of a smatphone navigator that uses GPS (like the one of google maps) to activate one of two vibromotors, there would be one vibromotor on the right arm and the other on the left, if a next turn is needed to be made (info from the navigator) a signal will be send to the the motor on the left arm, It will vibrate and let the user know that this next turn needs to be done. I need urgent help since I don't know which components I may need and how to develop the software or anything I will appreciate any hint.

Scholarship contest idea: evolving navigation behaviors

I am interested in the evolution of complex navigation strategies. As a first step, I am using the Avida digital evolution platform ( to evolve behavior that corresponds to chemotaxis in bacteria such as E. coli. Although they are very simple organisms, bacteria like E. coli have served as model organisms for studying the molecular biology of behavior, and have been studied extensively. Such simple organisms provide a good starting point for evolving simple behaviors that may eventually serve as a platform for the emergence of more complex behavior. Chemotaxis is a simple orientation behavior, performed by many different organisms, involving moving either toward (positive chemotaxis) or away from (negative chemotaxis) the source of some particular chemical signal, by sensing and responding to the chemical gradient in the local environment.The project I am proposing for the contest would port the software evolved in Avida onto the Create robot, and demonstrate the virtually evolved capability in the real-world environment. Since performing chemotaxis in air would involve dealing with turbulent dispersal of the chemical signal, I propose to use phototaxis or thermotaxis -- orientation to a light or heat source, respectively -- as an analog to chemotaxis. This will greatly simplify the experiments, since the problem will then be one of diffusion rather than turbulence. The robot will follow the light or heat gradient, tracking toward the source.Several things will be necessary to accomplish this. In software, the virtual CPU instructions of Avida will have to be translated to the robot. Because of the runtimes for Avida experiments, the evolution would be done offline; the robot would run the program that is the result of evolution. Hardware implementation would include the addition of photosensors or infared sensors, to allow the robot to sense the light or heat gradient. Care will need to be taken, both in the digital evolution and in the robot experiments, to ensure that the real environment is similar enough to the digital environment during evolution, so that the evolved program can function in the real world environment.Although tactic behavior has been implemented in robots in the past, to my knowledge it has never been done using digital evolution. An evolutionary approach has several advantages: 1) the finished program is discovered through evolution, instead of hand-coded step-by-step; 2) evolution may find novel ways of solving the problem that a programmer might not think of; 3) because of (1) and (2), the evolved solution may be more robust and adaptive than a top-down, engineered solution.

Need some input on boat propulsion

Can someone help me out with some ballpark calculation of propulsion power needed to move a boat? I do have some specific questions: 1. Propeller vs. Jet: Which one will deliver more propulsion given the same amount of power. 2. If it is typical electrical trolling motor type propeller, is there some simple formula to represent relationship of boat speed, power needed (hp), propeller rotation speed, and diameter of the propeller? 3. If it is a jet: Is there a simple formula to represent relationship of boat speed, power needed (hp), boat speed, and GPF of water to move the boat. I know that I am missing a few variables here like boat's weight and its water displacement.  I am trying to keep it simple. Any thoughts and input will be highly appreciated. Thanks.

Ancient technologies revisited - ancient "GPS"

This part is more theoretical but might be interesting anyway.To make this topic any interesting to you I have to assume you play with the idea of "alien" having visited earth in the past.If we check UFO sightings and map them like a nice man did for decades, then we find a weird thing appearing on a global map.It seems as if these UFO sightings are concentrated in various locations along a "grid".Some of this grid is the Ley Line system, a weak system of "lines" where certain energies act differently or where certain fields are detectable.Won't go into the magical part or why so many townships along those lines have names related to starts or constellations.Another part of the anicient GPS system is anomalies our earth provides, be it natural or "created" in the far distant past.I got interest after finding social media posts about an area claiming to have a messed up gravity in a very small area.Less than 100km away, so a nice bike ride with some testing stuff and off I went.Seeing a car appearing to roll uphill or balls seemingly doing the same is one thing, trying it yourself another.I did not notice any differences in weight or how the bike handled but I got a very weird "optical illusion" trying to tell my up is going down and the other way around.Did it in both directions several times with no change in this impression - even when focussing only on the spot in front of my wheel.time to invesigate further and to debunk some flaws other people made.Like how useless it is to use a self levelling laser level to "prove" nothing is wrong with gravity.If it is, then how would a self levelling device, depinding on gravity know? ;)Instead I did it dirt simple.Neon strings hung from lots of tree branches and twigs.If gravity is going nuts then those strings outside the affected area would hang at a different angle than the rest - they did not....Not even from a great distance, all just hanging perfectly straight and at the exact same angle.Ok, then, just an optical illusion due to the terrain after all....Last but not least I remembered my phone claims to have a gravity sensor and my watch has an altimeter and other sensors...The sensor test app did show some fluctuations but not any different to home or other places I tried.A bit more but IMHO not enough to justify any conclusion.However, my watch confused me.From what appeared to the bottom of Gravity Hill to the top I guesstimated a height difference of about 15m.My watch insisted every single time that when I reached the "top" that I was about 10m lower than at the bottom....Was a fun afternoon but I was no wiser in the end.Gravitational, magnetic and even geoligical anomalies are well mapped these days, same for undergroud lakes and water basins.Most of this data reached us from dedicated sensors on satellites in low earth orbit.If we have no troubles mapping them then it is safe to assume that a civilisation capable of inter stellar flight would be even more capable.And after god knows how long we finally even can measure the Ley Lines and no longer assume they are magical myths.All up it makes for very accurate system of navigation beacons that you can detect even if you approach on the night side.And since these locations on our continental soil as well as our ocean floors don't really change their positions it is highly accurate.If we say it is possible to use what earth, more or less naturally, provides to located any spot you like while still approaching earth from space - then what about more specific "markers"?We have the great wall, the pyramids, lines up stones from the stone age and then some things visible from space once you are in a good orbit.The ancient cities were often in what it today and already was back then, jungle.They must have stood out the same was as the pyramids - as huge clearings in the jungle with massive buildings.We also have all these nice animal figures in Peru.Too big to make sense from the ground, wrong angles to make sense from a great distance, unless you see them from above, or from orbit.All this was long shown to be coincidence, nothing to worry about or waste time on.But we learned this is not the case at all.The pyramids perfectly line up with the Bermuda triangle and ancient cites on the other side of the pond.From England to Rome you have a dead straight Ley Line and far too many are sitting right on top with unusal names.Attempts have been made over and over to use these existing references to find lost cities and more, quite often with success.We are very reluctant though to explore those signs pointing to the oceans...Finding just one of the mythical cities at a sea level matching the time period would mean that not just that myth might be true....I am not claiming I cracked the puzzle, just in case you wonder...Basically all ancient cities have mathy around them linking then to the gods, people from the stars.Even our cities following the Ley Lines are filled with these stories, be it the anient Greek, Romans or the great Kingdoms in Europe - the later all had their main residences right on the Ley line, some even on nodal points.Merlin was a great Wizard - or just some visitor with a far higher technology and knowledge of science...A very nice but somewhat very wrong theory claims the pyramids were actually build as huge power plants.You even find stories where it is (totally correct by the way!) calculated they could have been used as giant microwave transmitter to power starships in orbit like a recharge station....If that was the case then all identical pyramids, in terms of dimension would have been the same type of power station.Sadly they all seem to have only astronomical functions.Stonehenge is different, Rome is different, a lot of the old cities and temples are different.The thing common in all locations is Granite or even Diorite.Quarz is also heavy used in these locations throught ancient times.What do these materials have in common?For starters they are so hard, so durable that we struggle to work with them today unless we use diamond tipped tools.Even most carbide tools fail on Diorite...Secondly the fact they all have rather specific and organised crystalline structures.In some Indian temples this is even used to produced accurate and harmonic musical notes.If you want to build something that is certain to outlast your civilisation then you would choose these materials.Never mind the fact that the people in that time had no means to even scratch these hard rocks....A rather unusal approach to the problem started only less than 2 decades ago.Trying to measure more than dimensional properties of these creation, specifically these huge obelisk type "needles" of often hundret of tons in weight.Of course they could not really often use the real thing and to make do with smaller models they created.Key point was to match the exact type of rock from the same region as the big original, plus making sure the crystal structure is aligned in the same orientation.These guys first dicovered that these rock needles resonated at very specific acoustic frequencies.Nothing for most the spectrum but a very sharp amplitute amplification with little to no added harmonics for just a few tight frequencies.And yes, the max "elogation" was along the lenght of the needle with the tip acting almost like a resonator.The second and rather unexplainable thing was that these model sized needles also reacted to audi signals that did not came from a surface actuator but a normal speaker at close proximity.Did not stop them, just encourage them.It was not specified in the publication what higher band frequencies affected the rock but they claimed it acts like a high power amplifier for certain frequencies - with no detectable way where the excess energy comes from.If true it could mean that a lot of ancient structures we consider to be decorative could have actually been more like a lighthouse.Emitting a focussed beam of energy detectable from amost any approach angle when enterin our solar system.The thing you might now wonder about is: Why would highly advance civilisations need such beacons to begin with?This answer relates to the Apollo program - the Van Allen radiation belt, and some other strange things close to earth.The most significant other thing is our Ionosphere.Togeher they make radio transmissions next to impossible, only close to earth orbite, like where our satellites reside are in good enough reach.A long claim was that only certain frequencies can pass through these interference layers without losing too much energy or being distorted.Most of our planets emit a natural low frequency RF "signal".We can't detect them from earth though and used satellites and probes to measure and define them.Tesla's famous alien message was decades later calculated aginst these movements in regards to his location.Turned out he detected not aliens but the signals from two of our planets.Now this might be no big deal, I mean knowing it was not aliens after all, but it is in fact a huge deal!Tesla's receiver was only able to work in these impossible low frequencies that were claimed to be unable to pass through our interference layers!Much later we dicovered windows in these layers, even ways to caculate and predict their movements.It is now widely used to improve communications with our space probes and Mars missions.We still don't know if a suitable window was present for Tesla...If ancient civilisations or the gods visiting us for a while needed a way "to call home" or be called - what better way than using was is naturally there already?And it work the other way around as well.Send a strong enough and suitable signal to these structures and they would have to respond, maybe even in some audible form, no one really knows for sure it seems.My personal theory in terms of navigation and transmitting/receiving energy goes as follows and I hope you like it enough to make you own thought and conclusions:If we simply assume that certain anomalies or natural energies on earth are not just detectable but also usable it all could get a whole new meaning.Place a suitable object into an energy field and it can act as a "filter", an amplifier or as block.Like a Yagi antenna that you might find on your roof.What happens if have a theoretically endless conductor with a high frequency voltage going through?You have a very bad antenna of no use...But if you would place straight wires with a length matching the frequency you get a ton of small and powerful antennas....A bit simplyfied, I know but best example that came to mind to make a transition.If our Ley Lines and other form of natural energy phenomenon would provide energy to these ancient structures:What might happen if this "antenna" is just slightly out of tune and you "strike" it to produce a harmonic wave matching the energy going through?Right! You suddenly have a giant signal amplifier.And right again! You could actually try to send "signals" through the Ley Lines this way too.A harmonic wave would overlay the natural signal from the Ley Line and travel along it's path.Now the part you might not like at all, but it a key point of my own theory:If it is a natural energy that provides all this and we are able these days to detect these energies although we fail to understand, then where to they originate????If you poke your arm with a neeles then it hurts, poke a bit more and you bleed once you remove the needle, no one would do this for fun or even to get pleasure...Then why do we poke needles into our body, call it accupuncture and go home with such a happy face once the pain is gone???Guess you got my point already...It can't be denied that ancient civilisations already had a more than good understanding of things we onlydicovered or proved to exist thausands of years later.Even if we would exclude all godly and alien like things and just be ignorant and say that these folks knew the "body" earth" as good as a chinese accupuncture master would know your body and where to poke a few needles to heal you?If the energies are natural than our planet must produce them somehow, if you know how changes affect the planet you can "poke" it to get better - or to get much worse....Like the Butterfly Effect....You poke needle into Spain and in New Zealand you get a small earth quake....You poke a needle into Iceland and a temperature drop over atlantic makes the deveolping hurricane change curse to run out of steam over the ocean.You poke a needle into the right spot, stimulated properly and send a signal into outer space....If we can detect them easy from space, how strong would the energy level be if a burst of ALL the energy travels along the grid to combine in one single point?...How far could such a signal travel?How FAST would it travel considering no one, not even NASA dared to publish details about how exactly and what exactly was detected that matches these ancient old and till then just mystical energy lines and spots?A gravitational shockwave from an exploding star travels much faster than light....The ancient cultures of meaning knew exactly:Where the sun is in our milkyway,where our planets are at any giving time,at what angle our planets axis is, they even tracked this accurately,where exactly until recently unknown stars are within the Orion, Sirius and other constallations,when those stars where visible in the DAY or NIGHT sky,how exactly they moved when moved from earth AND how the position of earth relates the other way around,that there are Ley Lines, gravitational anomalies and more that we only learned to detect thausands of years later,about ALL the phsical, electrical and energy related properties of of suitable rocks and minerals,.....If they knew all this and we know that they did, why is so hard to believe they would have to have known that for a good reason, a purpose?I actuall don't care if they found all out themself, without knowing the wheel or the telescope...Neither if aliens, gods, people from the stars, visitors from another dimension or E.T. himself (herself, itself?) told them.But I cared for a long time about WHY humanity as a whole seemed to have forgotten all about his and how to use these unknown energies....So the final bit is not about my personal theories on ancient navigation, communication or energy usage.It is about the why it was lost...I make it a new chapter if you don't mind as it is not really about the GPS topic.

I want to make the Create a navigational robot. It can already navigate pretty well, but it is not very intelligent. I want to add Sharp GP2D120 IR sensors so that the robot can recognize an obstacle before it bumps into it. Then it will turn and look for a clearance before it will move ahead. This means it is very unlikely to get stuck. Currently I'm working on a CMUcam, so that when integrated onto the Create, it can follow a white line around, and might come in handy for other purposes as well. I am also toying with the idea of using GPS navigation as I have the receiver and antenna that was used for another project. If GPS is integrated, the Create will be able to move from one waypoint to the other while avoiding obstacles on its path.

Perhaps the robot could carry a stun gun to drive out raccons. It has to be able to navigate the "wild" underside of homes or buildings and be waterproof. It could have an articulated arm to mount the camera and poke holes to search for termites.

Navigation lights for boats? 112.5 degree - Port/Starboard (red/green) side lights & 360 degree white stern lights

Small boats under power are required to have a 112.5 degree lighting on the sides and an all-round white light on the stern. The light on the left or port side is red, while the right or starboard sidelight is green. At night, these lights must be visible for 1 mile, while the stern (rear) white light must be visible for 2 miles (minimum). These lights indicate direction... course. Led navigation lights are very expensive. LEDs are very cheap... So, why not build 'um yourself? My small craft uses a 12 volt battery operated trolling motor for power, and therefore, the idea low power consumption LEDS is very appealing. I've never built and LED lights, but I'd love to see some ides for small electric (or gas powered) powered water craft. Thanks

Embed SWF

A few years ago I did a project that was in the Instructables format. The only thing is that it's a SWF file and I wanted to embed it into my instructable. I've added it to my file library but it will only show up as an attachment. I know I can upload as a slideshow or video, but the project has it's own navigation. The link to the actual content I'd like to put up is here. The only question I really have is if I can embed this swf directly to page 1 of the instructable so that the navigation is intact and still functional. Thanks for any help!

Feature Request (I): Simple URLs to get to new profile sections

The new profile display is very nice looking, and (as has been commented elsewhere) a good reduction in bandwidth for highly active users.Unfortunately, there doesn't appear to be any simple way to get directly to a particular display. Several of us have noted that we would prefer to have the list of recent comments as the first thing we see. It would be trivial to do this if the navigation links produced proper URLs (e.g. if the value of the "show=" argument were actually visible). Instead, the navigation appears to be done via JavaScript in such a way that users have no access to the underlying query URLs. Could this please be fixed?
