K'NEX Concepts: Post Yours

Hello K'NEX Community, I am creating this forum topic for people to post their K'NEX concepts and ideas, both new and old, so that others can build upon them and/or put them into use. So if you have an idea, and you want to share it, or have someone work on it more, then this is the place to post it. I hope that this helps to spark some innovation in the K'NEX community, and gives people some fresh, new ideas. -The Knex Inventor

Knife's Edge- Sketch Up

This is a design I came up with and drew (i guess is the term) into sketch up. The Wings swivel up (shown in second Set of pics). This took about 10-15 hrs of drawing and about 2 hrs of rendering. The wings swivel to maneuver and when landing inside atmosphere. I haven't added weaponry and such so it's still a WIP. But suggestions are welcomed. Tech Specs: - Engines:             10 engines (4 small  large) -Take Off type:       VTOL - Class:                  Frigate - Operation zone: Space/ Atmosphere And for you sketch Up and rendering junkies...  used 40 passes in each render.

New knex assault rifle-Introducing the AR-4 commando- NOW POSTED!!!!!!!!!!!

ITS POSTED!!!ok. a lot of you hated my sniper rifle so i decided to make a new gun-an assault rifle. it uses the new mag idea from katarukito, the mag is a removable clip, the back of the stock is based off the Storm 221. its true-trigger.However, the rifle is still in progress, but pics may be released tomorrow(pics are up!!!). I just wanted you to look foward to something. it is not flimsy, except on the stock (fixed), bolt action.if i post the instructable, and you hate it like my sniper, i'll post two block trigger guns, and then quit knex for a good bitok, the gun is posted. i have introduced other guns with the same name, but they had problems with firing more than one shot at a time and jamming. if you have any problems with this gun's mag, blame Katarukito, because he designed the mag in the first placePROS-good range-not flimsy-has removable clip for 5 rounds-true trigger-pretty comfy-less friction than similar barrels-piece efficientCONS-mag sometimes jams-blame Katarukito on this, i was trying to put it on a gun-not auto-loading---you have to turn a knob on the mag after every shot (however, that produces a pro, Dsman 195276 pointed this out)-you cannot expand the mag to hold more parts-it is always going to hold 4, no matter what you doEXPECT INSTRUCTIONS BY SATURDAY!!!

Need help planning build for my self designed armor.

The first picture is of my costume that i call BURN OUT, it has stilts to make me at least as tall as a few people. Then the next picture is of a costume i designed for a friend. It is called ONYX STORM. I need to know how to see out of burnout's helmet. and i need to know where to start on ONYX STORM. so heres a wrap up of the two;      BURN OUT: burnout is a genetic experiment issued by the military. he is a heat producing bio-form that was issued a suit of armor both to protect him from the heat his body produced, and to institute a sedative that has kept his emotions under control and kept him alive for hundreds of years. then they trained him to fight and adapted his suit for battle. but after accidentally destroying the base he was housed in, he started to run out of the sedative and nearly died until he ran into ONYX STORM.       ONYX STORM: onyx was a five years old when he was taken into the military. he was told his parents were killed during one of his outbreaks. they were supposably killed during the northeast blackout, which he caused. he is a bio-form that produces so much bio-electricity that was powerful enough to power many testlaunches and research for the military.  then he was issued an aging drug to make his body age much faster, then put him on a sedative similar to burn out's. he was put through military training and finally found out what had really happened to his parents, who where killed by the station he was in. in a blind rage he destroyed the base he was in and built a hidout outside of detroit. where he found burnout. that's it, the back story for both characters. as you can see not much is known about burn out.so any ideas on how to see out of the helmets, how to get the various pieces and where to get them cheep?

knex concept

hi ive just had an idea for knex guns . basicly you build and post a knex gun not based of anything it would be just a barel mag reciver triger and handle just the basics then people would customise it and it would be done people could give you feed back and maybe post the body they made to be placed on other guns.

Knex Concept: 1

So just something quick. I got this idea for a more powerful semi-auto. Its basicly a slingshot, when you pull the trigger it pulls back the band and releases it in a smooth motion. Then you pull the trigger back and repeat.  Its nothing speicial, I can't even work on it now because of the railgun though.

How would you define the term 'Development'?

The term 'development' is very complex and confusing and I'm having a little problem defining it. I wanted to know, how others define it, what are their perspectives on the term 'development'?

Rolling House

The Roll It is an experimental house design that was developed at the University of Karlsruhe. To use the house in a different way, just walk along the inside to roll it to create a new up and down. There's a bed, an exercise area, and even a kitchen with a sink. I really wish I could find an explanation of how that last one works. Roll It via Core77

This is a Biodiesel Fuel Shed concept i thought of. It would be partly underground, have an exhaust hood, and a wet chemical sprinkler system. I thought of it for safety of the user/s in the shed, and also safety for the residents in the houses in the blast radius itf there were to be a catastrophic failure.

concept section suggestion?

Hi everyone it is i fidgety2 with a suggestion for my favorite site i have often had amazing concepts or ideas but have never been able to put them into action because i either lack the proper materials or time or both i would like to suggest a section devoted entirely to concepts and ideas for instructables it would be kind of like making a instructable without making the actual creation of course there could be pictures and schematics via google sketchup and auto desk-like programs so basically it would be exactly like a basic instructable but without the actual product that is all for now thank you, fidgety2

What is the definition of 'development' by World Bank?

I need a few definitions of 'Development' from different perspectives, to clear my concept. I know the term 'Development' is very complex and confusing, so I'm having a little problem defining it. I'm a student of Anthropology (Undergraduate) and recently doing a course on Development Anthropology. It'll be really helpful if anyone provides me with a number of definitions (of development) with reference and direct online links.

Knex Concept : True rifle

This is something I made when I was trying to make a K'nex rod spin in flight. I know there are true rifles like the Tempest, which uses a oodammo, and I know someone else twisted a rod to make it spin. This thing should be able to shoot normal K'nex rods with no modifications. I just built this, but I didn't make it into an entire gun. The red rod in the pictures is the ammo. This uses a K'nex wind up motor to spin the ammo. When you stick the ammo into the motor, it is like a bullet lock. The thing in the third picture is like a ratchet. It keeps the rod from spinning. It would have to be connected to the trigger, so it lets the bullet spin just when the ram hits it. Someone else could make a gun with this idea, but please give me credit for the idea.

Fast food/ restaurant sauce packet extractor!

This is just a crazy idea mostly for novelty purposes. I'm not advocating never paying for condiments again. But hey, maybe you just lost your job, you're a poor college kid, you're mad at McD's because the dollar menu isn't a dollar anymore, or you're just cheap! Or (in my case) you love exclusive sauces not sold in stores and would like a more efficient way of emptying all those hundreds of sauce packets you acquired into bottles :P Lol, let me go into what lead up to my "Huh, that would be awesome!" idea moment. I love(d) Taco Bell's Fire Roasted sauce. And darn them to heck for discontinuing it!!! Um, uh... yeah anyway. I loved it. Alot. So much so that I eventually built up a large cache of packets in my kitchen. One day it occurred to me I would use it more if the sauce was with all the other condiments in the fridge door. For when I prepare something for consumption and have thoughts similar or equal to "Hm, I wonder what would be good on this" I open the door, stair at the sauces, and evaluate. So, I saved a nice glass bottle (a steak sauce if I remember correctly), washed it, and squeezed many, many individual packets into said bottle until I had my very own "Bottle of Taco Bell's Fire Roasted Boarder Salsa Sauce". A practice I continued for several years. Many of my friends thought it was awesome. Other's thought I was crazy. In the end it didn't matter what other's though. The sauce called to me and I answered. Faced with the same decision I would do it again and I have no shame in that. Just in case you are actually interested, when I heard they were discontinuing my favorite sauce I made arrangements with the manager of the local taco bell to obtain their remaining boxes of sauce. And it was enough to last me until... today. As I squeezed the last few packets of Fire Roasted Boarder Salsa Sauce into its bottle that has served me so faithfully these many years an idea hit me. The concept of a machine that would extract the sauce for you. Pour packets in and sauce comes out. My first reaction was "this would have been very useful several thousand packets ago!" lol. Then I really started contemplating it as a "for the hell-of-it" idea and project. There are just so many different, possible ways of how one might work. Just with the squeezing mechanism (after the packet(s) is somehow automatically slit open). With a double roller one could squeeze several at a time or in serial progression. Or perhaps stack them in the same orientation inside some sort of press. Much experimentation would need to be performed to determine the optimal extraction method. Anyone interested in giving it a go?

Need help to realize an idea: "Projector-Ruler"

Hello there, thanks for attention. I have an idea "Projector Ruler" ,which can show a ruler or other measuring tools on the wall, so that can help people to read the information of target easily. My concept have won international design awards, including Spark Design Award and IDEA. I think this idea is possible, potential ,and required by the market. You can see more detail in video or by following link: P-Ruler I plan to realize this concept. However, my study background can't enough support me to implement it. So, I need someone who understand the principle of projector, rangefinder or other related knowledge to help me to build this idea. I hope that we can group a team to generate it and co-found it. (The funds can come from Kickstarter :D). If you're interested, please contact me or make a comment. Thank you. P-Ruler from Chang Yu-Chung on Vimeo.

Paper two stroke hydrogen engine

 Ok so I have this crazy idea to make a two stroke engine out of paper that runs on hydrogen and well ive allready built part of it just the piston head and cylider and stuff but if i lined the inside of the cylinder with tin foil would that be enoth to keep the paper from burning? and so ya anyways the engine of i have made allready is very sturdy each peace is 10 sheets of paper or more compressed for over 24 hours  now the compression im not two worried about because its more of the sheer pop of the explosion that will push the piston down well i guess thats how it is anyways but if the gas ignites anyways with oxygen why have compression  for this anyways because the explosion is going to be soooo small anyways that it wont really matter much.  the overall size of the engine is about almost 2" tall by about 1" wide on the widest part the bottom . So um I know by now im classified as "CRAZy" but that asside can i get some opinions and ideas plz. thanks MRN

Help Needed, 3D Printing Via Electroplating

A few years ago I saw a 3D printer that printed using UV reactive resin and a DLP projector and I obviously started thinking about ways to make this for myself. Recently I have been entertaining the idea of repurposing the old CRT technology with phosphors that produce UV light to replace expensive DLP projectors but I couldn't think of an easy way to do that. I was fiddling with various ways of repurposing one of my old CRT monitors when I had a decent idea. Instead of converting electron beams into light to harden resin why don't we harness the electron beams for the purpose of electroplating! Instead of resin we could use an ion solution and build models out of metal! Of course we would still need to replace the phosphors embedded glass screen with a conductive plate to serve as a non-consumable anode. Unfortunately I do not have the time or resources to do this myself so I wanted to post this to the Instructables Community and see If anyone felt this was a worthwhile project.  Please let me know what you think of the idea! I would love to see this turn into an actual project.

Hi-Cap horizontal magazine concept

Here is a concept I came up with a while ago. Basically, it is just a mechanism that allows a normal grey connector mag (I.e. One that would be used vertically) to be used horizontally, and so solving the problem of the low capacity of traditional knex horizontal magazines. However it is not without issues. The model used in these pictures is rather large, and there is an issue where the pusher cannot push the last connector out fully. Anyway, I thought I'd just I'd post this so if anybody is interested, they can use this concept and/or improve it so all issues are fixed. Just make sure to give me credit pictures: 1) overview  2/3)  overview of the mechanism 4) the red rod blocks the rotating mechanism so that no ammo falls out when not in use. Pull it out to initiate feeding

Non-stop Train Prototype

A train that doesn't ever stop or slow down? Sounds ridiculous (ly efficient). This design is a pretty interesting take on the concept, though liability issues and real-world feasibility will probably keep this from ever making it past the drawing board.Link

Anti-gravity Machine concept

This is a concept I came up with for an idea of an anti-gravity machine.  Let me just state for the record... I do not think this will actually work.  However, while I am quite certain this idea should not work... based upon my limited knowledge of science... it would seem like it could work.  Unfortunately I know I am never going to spend the thousands if not millions of dollars to build this concept to find out. The basic premise of the idea is the use of angular momentum to overcome the force of gravity.  Imagine if you will, a gyroscope spinning at such a high velocity that its outward force overcomes the downward force of gravity.  Naturally, one of the big obstacles is generating the speeds necessary to create the velocity such that angular momentum is greater than downward force. What I essentially propose is a spinning ring that is propelled in the same way as a maglev train.  Using Electromagnetic propulsion or EMP to accelerate a ring in a vacuum by the utilization of a flowing electrical current and magnetic fields may in theory generate the speeds necessary for the force to overcome gravity.  Unfortunately, the power to run such a vehicle and the weight to power ratio are significant obstacles. Two of these rings above one another I theorize can create tremendous propulsion if the angles of the rings were changed.  Using hydrolics to change the angle of alignment of these two rings may create incredible forward momentum.  Once more, such a vehicle would not be limited to operation within Earth's atmosphere unlike jet or other propulsion mechanisms.  In fact, it should operate at peak efficiency in a zero gravitational environment. This is all theory... and I'd love to know if it is indeed as crazy as it sounds.

Interesting Speaker Idea

Well, this is a totally random idea I had about how to see sound. I would like someone to try to build this if they have the resources available. Pretty much it is an airtight box with an woofer driver in it. On the top is an clear acrylic tube with a light ball in it. There is a rod across the bottom of the tube to keep the ball from falling out. The idea is when the driver moves back, the ball is pushed up in the tube, and when the driver moves forward, the ball is sucked down.

(if its possible that is) So let me know if this is worth pursuing... because i'm sure someone must have thought of this already... I'm also nowhere close to being a developer... with that said lets jump into what i want to call Basically i want to use our EYES to reflect Infrared to the wiimote to calibrate the movement ... and capture it and do something cool with it...    -  steer a car in a racing game...  -  look around in a 3d environment  just by moving ur head...  -  maybe even use it as a mouse and Wink with one eye to click? im waiting for a friend of mine to find time to build me that IR LED board Jonny Chung used in one of his videos.

Anti Gravity Idea...

OK I had this idea. I was online and thought up this idea for an anti gravity machine. This is it: use extremely static negatively charged materials for anti gravity. It could work the same way lightning clouds do. The base of the cloud is negatively charged and the ground become positively charged. Now if the material of the anti gravity "thing" is charged with static electricity, wouldn't it repel the ground? Now I am by far no expert in any of this...I just thought it up. What do you guys think?

Futuristic Concept Guns that may be worth a Build with your twist!

Ahhh... I feel sometimes the k'nex gun builders community lacks a bit artistic visions, so I scraped the worldwide web for some images that would pump some artistic juices into the community. With no offence to our replica builders out there, (you guys are awesome at what you do!) but I feel that building a k'nex gun is an art. Trying to create that right balance of flow of a gun while incorporating a twist that catches the persons eye is a challenge, a skill, and I feel may be a bit more challenging than making a replica. With replicas you have the comfort of a defined shape and measurements, when guns like these (some virtual, I know one is real, the harmonica gun) are built to be within a similar scale but again with that unusual and pleasing twist of the imagination.  Again I don't mean to offend anyone with the idea that replicas are not cool, replicas are awesome and I find it really hard to stay within a replicas measurements (more power to the people who can). I would just like to see some more unique visions of the builder. Build a gun that defines you and your vision of what a great gun looks and feels like. Then make it perform how you want it too. It's a complex process capturing the beauty of a well crafted k'nex gun through not only aesthetic appearance, but physical performance. These unique guns are what defines us as a K'nex gun community, a community of artists.   At the end of the pictures, I've included a couple of my best Art. (two which didn't perform as planned but nailed appearance)

Team Ball Concept

Dear all,first of all, hello to all of you, I'm new to this site, but I've already seen some wonderful things on here, and they are a true inspiration source for the projects I'm working on during my study as an Industrial Designer.I've got a question about a concept of mine, which I will explain briefly to give you an understanding of what I'm trying to create:When playing a sport, let's take football (by which I mean soccer) there's a ball. My idea is to make the ball represent the ball possession (or actually the ball passing between players) of the teams. For instance, you have a blue and a red team, and what I want to do is make the ball color almost entirely blue if the blue team is in ball possession all the time. This way people will be more stimulated to play with eachother, passing the ball to eachother instead of scoring goals individually.The way I want the ball to change color, is by making it detect when it's being kicked, by a football shoe (which has to have some implemented technology as well). So everytime it's being passed from one player to another of the same team, the ball will color more blue or red. I need some help with the technology as I'm totally new to this aspect, 1. How to make the ball change colors? (LED's, or optical fiber: http://www.imtech.nl/SiteContent/EUPortal/Images/ImtechNV/newsroom/succes/17%20glasvezel.jpg, or any other suggestions?)2.How to make the ball communicate with the shoes?One thing I've been looking into is RFID - chips/reader, http://www.youtube.com/watch?v=PaNnOHSJ-cQ, and then make the RFID-chips with a very limited range, so that only when the ball (with the reader) is close enough, the reader will detect the chip.But this seems like a last option, and I actually want something better.What I basically want is that when the shoe and the ball touch eachother, the coloring will happen. The requirements are that the shoes, must contain unique information so that the ball will know on what team that shoe is, another thing is that it can't be fragile, as the ball will be kicked by the shoe.Now as I'm fairly new to technology, I don't expect to build something with the best technology possible. As I have to write a final report, I will just present the technology idea in it. But it would be great if I could actually show an interactive prototype version of my concept. Therefore, if you have any suggestions, please write down the best possible way to create this, and a probably less perfect way that I can demonstrate (I'm willing to learn a lot over the next few weeks).Thanks in advance!

K'nex Concepts 13

Spiral Drum Mag: Drum mag with two rods that rotate in one direction to push rounds to the outside of the spiral and into a firing chamber. -by Oblivitus Layered Drum Mag: A drum mag with multiple layers that fill the entire space within the drum which both rotates with an elastic and is pushed up by an elastic. When the outer layer is emptied of rounds, the drum moves up and the next layer begins emptying. This layer changing would be achieved by making the rounds press upward against a flat surface on the gun. -by Oblivitus These concepts have also been posted to: https://www.instructables.com/id/Knex-Concepts/
