DM-TD-SA?

Alright remember when dsman and Thedunkis were talking about combining their side arms to make a perfect side arm? Well I was searching randomly while I was bored and I came across an image titled "TDS2" with tags like "PSA, DM-TD-SA" so I started to wonder if this happened to be that pistol. It must have been a big secret as they darkened the image too. This sounds pretty cool I really hope this is real. Dsman and Thedunkis have really cool side arms and having them combined would truly make a awesome side arm. What do you guys think? P.S. Dsman and Thedunkis please don't kill me if this is true. I'll delete it if you want. Edit: TheDunkis and Dsman claim all rights to their photos and guns and may not be shared with anyone else

UMP-45 K'NEX gun review

This gun has found its way into the favorites of many members. This review should answer the question: Should I build it?SPECSPower: 10 out of 10 Why? It went through paper at 5 feet, got stuck in cardboard at about 5. Looks: 9 out of 10 Why? Looks EXACTLY like a UMP-45. Well, with the wire stock, it does.Ergonomics: 7.5 out of 10 Why? Feels...odd to hold.Innovative...ness: 9 out of 10 Why? Pretty much everything is new, but...y'know.Accuracy/Sights: 8.5 out of 10 Why? New sights! They...are...awesome. But, the 'bullet' veers. Oh, WELL.Magazine: 8.7 out of 10 Why? Well, it's good for the most part. Never ever jams. But if you press directly in on the mag switch(the white rod) it messes it all up. So you have to push down and in. It's also not a very good connection; a few bumps will break it off, turning the magazine into a shotgun shell, loaded with gray shot.NEW! Rail system: 7.5 out of 10 Why? The connections go AROUND the connectors, not in them. So that makes it kinda flimsy.Piece consumption: 7.5 out of 10 Why? This doesn't use TOO too(I meant to have 2 toos) many of your pieces, but you might not be able to build anything too big for a little while. Stocks:(We'll examine BOTH stocks.) WIRE STOCK: 9 out of 10 Why? Looks better, but kinda flimsy. Not REALLY, though. FULL STOCK: 9.5 out of 10 Why? Sacrifices looks for strength."Toy" parts(the charging handle was the only one I could really find)7 out of 10 Why? So...FUN!! to just slide back and forth. Pointless, but cool to have. Like a laser cannon.War Weapon: 9.5 out of 10 Why? Let's just say it'll have 'em beat. If they've already built this, they'll probably run out of sheer terror like bunnies. (?)Overall: 9.3 out of 10. Why? Do you really need a Why? for this?Great gun. I recommend it to any H&K;(drools) fans, or if you just want something cool.TheDunkis scores again.

Another Challenge from TD

This is another quick idea I got just because I'm kind of curious of what you guys would make. Basically all you need to do is make a realistic looking gun that isn't actually a real gun. You can base separate parts off of other guns if you want (like using M16/4 magazines for example) but try to make it as unique as possible. Make sure it would seem like something that could actually be made. Give as much fake barrel as needed depending on the type of gun. Also make sure it actually works for both loading and firing. If you have any "futuristic" concepts that still seem possible and not so far-fetched (kind of like the super v concept) you may include them as long as if you give a basic idea of how it may work. I'm also interested in features that make them look even more like a real weapon such as removable magazines and mag releases, charging handles (fake or not), selector switch, sights, etc. Shells would be another cool feature but not required. Anyone up for it? I'm thinking of making something myself.

TheDunkis's Display and Request Thread

Alright I'm not saying I'm special enough that I should have my own little personal thread dedicated to what I do but...I'm lazy enough that I should have my own little personal thread dedicated to what I do. Why? Simply that. I'm lazy. I don't feel like making a thread/slide show for any new gun I make but I don't want to post it in some other random place. I also don't want to go around asking for ideas whenever I'm stuck. So to put it simple I'm going to display whatever current projects I have here and I'll also take requests. ~Current Project~ FKG (Folding K'nex Gun- Yes very original...) Alright I saw SK's FMG and I wanted to try one out myself. It didn't end up as pretty or as functional as SK's but it is compact and in a very early stage of design. I'm not sure what to do with it because it's at the point where I'll have to completely butcher it to improve it and then that would require whole new ideas on getting the parts that do work to keep working. So as said the only real big difference here is that it's more compact than SK's. Some other differences are -Held in place by a "grip" rather than a "bolt" -At the moment not rubber band loaded -Simpler trigger -Double hinge thingy for the stock to gun connection. So instead of a fixed pivot swing, two different areas rotate to move the stock from the very bottom to just behind the gun. Otherwise it was to fire dark greys with greens as well with a hopper but right now it doesn't work so well. I think the barrel has some friction in it from the way I set it up. I could loosen it up but I'm just going to redesign the gun anways. Should I continue? Or shall I try making a bolt action gun similar to Zak's (but different enough)? Or I'll try something completely new.

Help With Warcraft III World Editor

I have recently been creating a tower defense map with the warcraft world editor and I am just starting to make all the waves. My map is a Solo TD where the creeps move through multiple checkpoints. The problem I'm having is that if a creep manages to step into a region that he is supposed to later on (if someone mazes and makes it so they have to go through the last region before the first) then the creep dies. I was wondering if there is a way to make it so they HAVE to enter the first regions before the others apply to them. There is a way to do it with variables but that way is going to take me FOREVER. I was wondering if there is a faster way than just creating a load of variables so when a unit walks into a region it records it and after a certain number the next region is activated. That way also has a few flaws that would be difficult to maneuver around. Thanks in advance! The red words in the picture say "makes them go that way". It did't show up as well in JPEG form.

Oodassault Pistol Review

This is a review of TD's newest pistol on Ibles, the Oodassault Pistol.Review requested by TD.Range: 7/1025-30 feet with 2 64's. Could be better, but not very bad for a pistol.Looks: 9/10Bleh. I don't look for how a gun looks, just reliability and power. But I'd say it looks pretty good. Strength(in terms of holding together) and Comfort: 7/10The back of the pistol exploded once for me. I wouldn't recommend putting too many rubberbands, the back may explode if you do.Also, the thicker part or the handle (middle layer) was pretty flimsy for me, and broke pretty often. After replacing the blue clip with a tan clip, it stayed in place and never broke off. No biggie.Other than that, very sturdy.Handle's very comfy, no rods sticking out anywhere.Reliability: 10/10Not once has this pistol jammed, or the trigger system failed. Power: 8/10Not too bad. Dents my super-special awesome cardboard (with extra reinforcement) a bit from a good 5-10 feet away.Accuracy: 9/10This uses oodammo, of course it's very accurate. I can hit a 3-inch target from about 15-20 feet away (and I suck at aiming lol).Extra Features/Sights: 7/10Sights are kinda unnecessary, but fun use if shooting at stationary targets from a REALLY short distance. Safety is also fun to play with, and pretty innovative. Nice work, TD. Piece Efficiency: 10/10Uses very little parts, and gets the job done.Overall: 8.4/10Very good pistol for playing around and war (for a sidearm). Reliable and powerful (for a pistol), this is a must build for anyone with the pieces. Ible: https://www.instructables.com/id/Oodassault-Pistol/EDIT: I have a bad sense of measuring. My friend with better depth perception came over today. He estimated about 20 feet flat with 2 #64s. Whoops :SAnd TD's right, I do rate too high. :S

New Side-Arm DMTD (name pending)

Well some of you might have heard dsman and I are making a new side arm mainly by combining our side arms and then adding even more features. Some things we (well I) plan on -Stronger and just as reliable as DMS -Small and as comfortable as TDS -Removable magazine -Slide -A new feature I'm working on. Adjustable site for aiming at distances. So yeah we decided to team up because I honestly just got tired of competing with dsman. I have some questions for you though What ammo do you want us to use? We are leaning towards dark greys. Also what other details do you want? Such as what kind of trigger (true obviously) and also do you want it to be detailed like the gun down below or do you want it to be straight forward like the TDS? Give me any other features you want. This gun isn't what we are working on...yet. We might use it as a base. For anyone curious this gun is my newest version of what used to be the D. Falcon from the video comparing our side arms. It was what I was working on to beat both of them. This is mainly for the concept removable magazine I'm working on.

Replicas?

Ok, so I decided to dabble in the art of replicating recently. However, I dont really know what gun I should replicate. What I know for sure:I dont want to replicate a gun that has been done a million times, like an AK-47 or an M4 Carbine.I dont want to do huge replicas that use too many partsThe guns I will replicate are not limited to just real life, I will also do guns from video gamesNo pistols. Most pistol replicas are just TDS copies with cosmetic mods.Post a picture of whatever gun you think fits these requirementsI was considering doing either the Halo sniper rifle, or the FAMAS. If anyone else has a suggestion, Im open.

K'NEX Magazine Comparisons - 5.56 NATO, STANAG Magazine

On thing that makes any K'NEX gun replica more accurate is the magazine. Trust me, if your magazine is to big or to small, it will make the whole gun look bad. As this is the case, I decided to "clear up" the small argument about the size of 5.56 NATO magazines, as some people are incorrect on the size of K'NEX magazine that they use. As you see in the pictures below, TD's magazine (yellow connecter - white rod - yellow connecter) is more accurate than the other type (white connecter - green rod - white connecter). The latter version (white connecter - green rod - white connecter) is quite a few centimeters too long, and is more accurate for some 7.62x51 replica K'NEX guns.

UKP V3

All 3 versions now there, goes in descending order (v3, v2, v1) v3 slideshow https://www.instructables.com/id/UKP-v3/ Back Story (skip if you don't care who I am)  Hello! Most people probably have never heard of me, and for those of you that have, you're probably in the same boat. I was part of the raise of knex guns, you could say. I helped to change the idea of knex rubber band guns back in my day, 4-5 years ago I think. And then began to dabble into knex firing guns.  Project History  The UKP was my take on the common pistol of knex. Way back when there were two options for a sidearm, the TDS or the GD-1. Both in their own ways, were excellent systems, except the GD-1 was massive, with a larger round and slide action, While the TDS featured a more compact design, without a slide (until later, still not the best). The original UKP was designed to create a medium between the two, and that it did, with some minor flaws. It's biggest set back was the lack of a slide. The UKP v2 ,2.1, 2.2, 2.3 and so on were my attempts to fix that problem, which it did well at, but it wasn't a complete success. It was never released due to my inability to work out the kinks. (note that the UKP v2 is pictured below) The Current UKP V3 I've come to realize, that I will be going to college soon, and that all knexers release something spectacular right before they leave the world of knexing for a while, or longer. So the UKP v3 will be my attempt on that. I will open a slideshow and various youtube videos throughout the production to keep anyone interested informed. This project has a deadline of mid august, as I leave the 20th.  Summing Up If you've never built one of my UKP's before, I highly suggest you do, or at least keep an eye out for the latest release. They feature high removable magazine capacity, exceptional range for the pistol class, and an overall realistic feel and performance.

What Should I Make Next?

Alright I have ideas but I have no clue which I want to do. So I'm simply going to ask you guys. Which of these should I make? By the way check out my TDS Instructable I updated it with a simple slide mechanism. Compact Assault Rifle Like an AK-74u or an XM8C. Basically I want to try to make a small gun that has some good strength. (an exact gun you want me to do would be helpful) Power Weapon/ Sniper I dunno this is something I really wanted to make for a long time after getting some more pieces. I've had I don't know at least 4 or 5 failed attempts before I don't like what I'm making. I have yet to make a weapon simply dedicated to power. Another Side Arm My TDS is great and all but it could have been a lot better. Basically I'll try something new and see what I get. Crossbow I suck at these...and that's why I want to try it out. It's another thing that I think a knexpert should have along side a side arm and sniper. What I would plan out then is a repeater so it has a magazine. Siege Weapon Something else I was curious about. A catapult or maybe a scorpion although it would probably just end up being an even smaller version of I_a_C's cannon. I'm not to enthusiastic about this one. Other Gun Replicas I guess I could try to make other replicas of bigger weapons but unlike the compact assault rifles they'll most likely be more for looks than function. Any Combination of the Above? I don't know maybe a cross bow pistol the handle loads sounds kind of cool although it would sure be a challenge. Or if you have other ideas tell me. Those were what I could think up at the moment and would be willing to do.

iPod Touch Rail Mount

Hey!I got a Roland V-Drum kit last year and there's an aux input for mp3 players. I use it with my iPod touch to play along with songs.My problem is, I rest my iPod on the control module and not only does this then block half the controls, but it sometimes falls off with furious drumming.So I though to myself, I wonder if I can buy a rail mount so I can have a cradel attatched to the stand. I knew you could buy motorbike iPod cradels, but all of these weren't wide enough to accomidate the 35-40mm diameter of the stand. So I thought about making one.But I can't come up with any ideas.The stand I have is this:http://www.woodbrass.com/images/woodbrass/BATTERIE+DRUM+ROLAND+TD+9+KX.JPG(not the drums though...

Handle Pump Pistol (HPP) / Mini Support Weapon (MSW)

This little prototype (the Handle Pump Pistol [HPP] / Mini Support Weapon [MSW]) came out of an idea I found in this forum topic. TD said to KILLERK: "Seeing how the main drawback to this weapon is its single shot with long reload, might as well throw a mini shotgun on it." And then it struck me, I should try that as a tribute to my friend KILLERK. This is the start of that project. It is a handle pump true trigger under-barrel pistol (XD, say that ten times fast). I thought you guys might like to help me out with it. It has two main problems. Problem 1) Pin-pull is not good enough to get any range Prob elm 2) No magazine / loading area. -The Red Book of Westmarch (NOTE: this forum topic was written in haste, words might be misspelled, capitalization might be off, punctuation might not be correct, ect.

Just HOW contraversial is this really? (Also: The Dunkis's Flat knex pistol review.)

I know this subject has been brought up before, but I'm the first one to actually have video documentation on this topic to my knowledge:  While I'm at it I might as well review TD's Flat knex pistol because I don't feel like making a separate topic for that: Design- 7/10.  It succeeds at being compact and flat but this results in some tradeoffs, such as a tiny handle.  Bullet lock does not work too well, the ammo falls off given a good shaking. Range- 6/10.  About 25 feet with oodammo, with 2 #64's.  Any more bands, and I have problems pulling the trigger.  I'm gonna go easy on this rating because it's a compact gun for showing off. Comfort- 7/10.  Sure the handle is flat, but it's also tiny and pretty hard to grip if you have larger hands.  Also the pin tends to hit my hand a bit if I'm not careful due to this. Innovation- 8/10. It's the first truly flat knex gun, but it also sacrifices functionality. Trigger- 8/10.  It blocks near the back of the barrel, but the part you pull breaks easily with more than 2 bands.  It's comfortable though and the spacers don't fall off. Overall- 7/10.  It's a novelty show-off but nothing too powerful.  Great for stealth if you ever needed to hide it.

Shotgun design (constructive criticism welcome!)

Alright, this is my new shotgun design.  I have been working on it since I decided to get back into K'nex, however, right now I don't have the pieces to build it, so it will remain a concept for now.  It includes a horizontal magazine that I have designed, a pump, and TD's ram.  The ammo will feed into a mechanism similar to that on the zkar, pushing it upward so that it rests on a pusher which is located right below the barrel.  This pusher is externally connected to the rod in the front and is held in the forward position by a rubber band.  When the pump is pulled back, the ram is cocked, and the loading ram is moves back as well, placing the ammo right below the barrel.  When the pump is pushed forward, it pushes the loading ram forward, loading the ammo into the barrel.   Though this model is not proportionate, I think it accurately gets the idea across, and I was hoping you could give me feedback as to what could be wrong with the design, or you can just feel free to tell me how much you love it.  Eventually I plan on adding a stock that houses a bullpup sling mech, using the guide on the ram to act as a pusher for the rear BTS of the sling gun.   I am pretty sure I can pull this off, but I need the pieces first, so feel free to test this concept out and let me know what you think.  Thanks. -Kinetic  * note in the key it says that the green circles are protruding rods, this is a mistake and the blue circles are actually the protruding rods

This is the contest me and TD were/are organizing. LOADING                                                                                                        MeZak: 4/5. Very, very quick. OodAst3.6: 4/5. Not quite as quick as the MeZak, but it makes up for it in comfort. TBOS: 1/5. Truly agonizing. EAP: 3/5. Not bad. Tougher and more time consuming than the OodAst and MeZak, but much better than the TBOS. STRUCTURAL INTEGRITY / DURABILITY                                                   (Note, I'm rating according to how "Bendy" they feel.) MeZak: 4/5. Really sturdy. Barely any bend. OodAst: 4/5. Really sturdy, but again, just barely less sturdy than the MeZak. But not so much as to lower it a whole point. TBOS: 2/5. Only 3 layers. Bendy, bendy, bendy. EAP: 4/5. 5 layers, so it's obviously pretty good. RANGE                                                                                                             (The first range is with 2 #64's, the second is with the maximum amount. Measurement was averaged out of 5 shots. I used Google Earth, but I promise I didn't cheat.) MeZak: 4/5. 39 feet. 63 feet. (Max. of 6 bands.) OodAst. 3/5. 44 feet. 52 feet. (Max. of 4 bands.) TBOS. 3/5. 41 feet. 41 feet. (Max. of 2 bands.) EAP: 2.5/5. 37 feet. 37 feet. (Max. of 2 bands.) FINAL SCORES                                                                                              MeZak: 12/15. #1 OodAst: 11/15. #2 TBOS: 6/15. #4 Ouch EAP: 9.5/15. #3 So, congrats MeZak, you win. (Though, I'd like to point out, this is based pretty much entirely on performance, not personal opinion.)

Ultimate Knex Contest has been changed...

Alright well this takes too long so I might as well just start it. Instead of entering and making it a contest anyone can nominate a gun that fits the category. Sorry to disappoint anyone if I did. We are still comparing guns...now we're just comparing all of them instead of entries. Alright from now on...no voting for yourself. Put it this way. What weapon from each category would you want to have and use most in a battle? Don't just put pride in your weapons. Also it would be great if you actually built the gun you vote for...don't just make assumptions...well I guess except for best replica. Weapons mentioned Best Side Arm- TheDunkis with the TDS Radioactive with the SPEC-9 Dsman with dsman's Side Arm popomaster with the glock Most Innovative Gun- popomaster with the glock Best Grenade/Explosive TheDunkis with the D model splodies/ DX8 Splody Bomb I_am_Canadian with the War Bomb flames with the F25 Anti-Personnel Grenade Best Replica of Another Weapon- TheDunkis with the AK-74 Katarukito with the Dragunov Best Gun Overall I_am_Canadian with the super cannon dsman with the DD-27 I_am_Canadian and knexgunner12 with their Battle Rifle I entered some of the guns I remembered but if you have other guns you want to vote for and they fit the category then go ahead. Just copy the form and type out the name of both the creator and their weapon under each category. Best Side Arm- Most Innovative- Best Grenade/Explosive- Best Replica- Best Gun Overall-

Questions about K'nex gun features. Answered

Hey, I'm Stale56 (as most of you may know), and I'm building a K'nex gun right now. I have several questions about some features on K'nex guns. 1. What type of barrel will get further range, a TDS style barrel (where it is layered), or the type on Foresthell12's K'nex pistol V2 (snowflake with grey/red rods connected)? 2. Is a firing pin that comes out of the barrel better than one that doesn't stick out of the end of it? WHAT I MEAN: Let's say a gun with a tube barrel has a body that is the length of a red rod, and a firing pin that is a black rod. When the pin is not cocked back, and not ready to fire, the firing pin is sticking out the front end of the barrel. Think of all those "Smallest True Trigger" guns. They have a small firing pin that is a white rod, blue rod, etc. Now imagine if you made the firing pin a yellow rod. You can imagine that the firing pin will stick out of the front end of the barrel. And that is what I mean in my question. 3. Does firing pin size matter that much? EXAMPLE: If you have a yellow rod firing pin that isn't pulled back that far, and a black rod that is pulled back the same distance as the red rod, which will have better range? I'm assuming the black, but I might be wrong. 4. What is the best type of bullet lock? 5. I know that black rods are stronger than grey, but if you have a grey rod for the firing pin, and replace it with a black one, will it go further? If so, will it be alot further, or only 2 inches further Thats it for now, I may add some more questions later. Thank you for you time.

Oodassault-Pistol Review

Here is my take on the Oodassault-Pistol By TheDunkis.Link: https://www.instructables.com/id/Oodassault-Pistol/Before I start, I'd like to highly recommend it.Trigger:Strong,Realistic,and reliable.Also has a safety, and is very innovative.Mag:Small, but it is very reliable. Note that it is slow to reload.Is also very new.Handle:Not much to say, but it feels good,and is very sturdy.Barrel:It looks iffy, but it is really good.The bullets fly extremely straight, and are pretty powerful.Overall:Innovation: 10/10 Almost all of this gun is 100% TD.Accuracy 10/10 I can hit a small target from 20 feet using the sights. Trigger: 9/10 Feels great, and is very reliable.Strength: 8/10 Like most 3-layer pistols, it could be broken quite easily.Range: 8/10 It shoots quite far, and maintains it's accuracy.Comfort 8/10 Trigger feels very good, and so does the handle.Reload: 8/10 The mag is slow to reload,but it is VERY reliable. Mod room: 8/10 This gun could have many mods for various reasons.It is built so you can easily change things like: Change ammo type (?)Add longer barrel, stock...etc.....Looks 7/10 It's not very realistic, but it looks cool.Raw Power: 7/10 Oodammo tends to be not very damaging, but it more than makes up for that with it's accuracy.83/1008/104*I love this gun. Love it.But the mag is too small and slow to reload.This makes a great sidearm, but just don't plan on reloading this while running away from the enemy.Link: https://www.instructables.com/id/Oodassault-Pistol/ It would make a good gun to make two of then have a mini war

Kriss Super V (Vector for you COD fans)

I've finally gotten around to finding my camera, and well, I figured I might as well put something up, considering I havent done that in a while.  What we have here is a Vector done around the tds slant design. This allowed for the closest and most realistic feel. (it may not look it in the picture but the slant does feel just right, even though its about 10 degrees off) the handle is quite comfortable and the stock is moderately sturdy. the magazine isn't finished yet but it will fire grey connectors with the little green pegs. the front handle is actually quite... poor and doesent support much weight at all. If anyone has ideas for that let me know. the underbarrel ( where the handle is) and the first 12 inches of the gun have rail support and I am pretty sure the reflex sights that worked with barrax's ACR would be compatible for now, at least until I make my own. Has a "creative" trigger that hasn't been tested so, "we shall see" The rear portion of the gun that isnt filled up (cuz I know its driving you all crazy) is so you can pull back the charging handle, which ends up making the gun shorter.  This is good because this vector is not only a vector, its a replica :) The gun only varries by about 1 inch from front to back and by about half an inch from top to bottom.  If anyone has any suggestions let me know. Just linking to the new slideshow, it has the latest pictures: https://www.instructables.com/id/Knex-Vector-Kriss-Super-V/ V 1.0 General frame with huge open area V 2.0 The one thats not open, has a stronger foregrip and a black dot sight :), and the stock is epic V 2.1 Added a trigger guard

K'Nex Semi/Fully Automatic Gun Concept

Alright, I stink at MSPaint, so here it goes: LouisXIV's famous semi-automatic "gun" (https://www.instructables.com/id/Knex_Powerful_Semi_Automatic_Gun_1/) has a lot to do with this. I was thinking how to make a semi-automatic gun when this idea popped into my head: You have a bunch of grey connectors in the barrel at a time, but either a gap just barely too small for them at the end, or LousXIV's mechanism, is at the end, trapping the bullets in unless under pressure. There is a notched firing pin* that you pull back (see http://www.google.com/imgres?q=toy+smg&um;=1&hl;=en&sa;=N&rlz;=1C1CHNV_enUS370US370&biw;=1680&bih;=935&tbm;=isch&tbnid;=ijx0IyYxpqN_jM:&imgrefurl;=http://www.kapowwe.com/toy-mp5.html&docid;=dBcMAxK0eQoSqM&w;=573&h;=297&ei;=zSMzTtSuDY260AGU2bWMDA&zoom;=1 It is a toy that one of my friends used to have, you pull the orange tab back, and as long as you hold the trigger, the tab keeps going forward until you have to pull it back again). The trigger is a regular trigger, say, from TheDunkis' TDS, the difference being that the part in the barrel ends in a green rod to lock into the firing pin. There is tremendous pressure on the firing pin. When the trigger is pulled, the firing pin pushes and squeezes the grey connector(s) out of the barrel, but when the trigger is released, it locks into one of the notches on the firing pin. I am not sure about a detachable magazine yet, as they would all have to be lined up facing the end, but you could certainly load in a bunch at a time and see. *A firing pin with a concept used in conjunction with motors to make an automatic turret, you would have, for example, a grey rod, and lined on it are a grey connector, two blue spacers, grey connector, etc. **THIS GETS ITS POWER FROM THE PRESSURE ON THE FIRING PIN FROM THE RUBBER BANDS, THERE IS NO STRIKING MECHANISM. LIKE ALL CONCEPTS, IT WOULD PROBABLY BE WEAK, BUT CONCEPT GUNS ARE (ALMOST) NEVER MADE FOR POWER. Feedback is appreciated.

My viewpoint

Ok, people are going on about this whole Utopian idealism of a united Instructables. I can guarantee you, it will not happen. I found it highly ironic that posts by DJ and IaC kicked up further arguments (mainly involving Lithium, Slime Q Slimedog, and many members of the K'nex community). So how about this; we stay out of each other's way. It has worked for 2 years, why not now? Also, about the K'nex community, I agree with the whole idea of being happy and building for fun. However, if someone does not build for fun, should they not be allowed to contribute any more? For example TheDunkis has made it clear he does not build for fun. Great. Now, who has the right to tell him he is wrong for doing that? I myself enjoy building, but I also enjoy the elation of discovering people like my project. I imagine that is the same for everyone, but to differing levels. I think that deep down, TD does enjoy building, otherwise he would not post half as much. If it was purely his wish to please that drove him to build, then it would be a chore. Finally, I think the K'nex community really needs to grow up and learn to take some criticism. To prove my point, I imagine several members of the site will have a go at me for saying this. Spelling and grammar is becoming better, but there is still a long way to go. There is a disturbing level of immaturity too; just because it is the internet doesn't mean you can just post whatever with no consequence; a point proven to me when someone from my school was found by staff to be a member of the BNP on Facebook. EDIT: I also think it is pathetic the way some people are under the illusion that the 'non-knexers' are ganging up on the 'knexers'. Calm down, it doesn't even really matter if they are. So, there are my views. Feel free to comment nicely, and if you wish to comment in a demeaning way to others, save your dignity and check you are not proving a point I have made in this topic before posting.

A proper K'nexsayer review (updated with pic)

Well, I built the knexsayer a few minutes ago, and I realized there were no proper reviews on it.  So I made my own. BODY: Stock: 9/10  Pretty strong, but still not enough to hold the gun up when I hold it there by itself Handle: 9/10 Very comfortable and strong. Body: 9/10: The individual panels are flimsy, but together, It's a literal brick Pump: 7/10: Eh, it FEELS a bit flimsy in my opinion on the rails, but its still enough to work, and in reality, it's decently sturdy.  As for the pump itself, nice work. Barrel: 9/10: Very strong, but front heavy and may be difficult to construct for a newcomer (not really difficult for me) Turret: 8/10: Its really cool and all, but the only connection it has to the barrel seems flimsy. Looks: 10/10: I like the look of it a lot Overall: 8.8/10 Performance: Range: 9/10: Gets 65 feet with 4 #64 bands Power: 9/10: Pierces cardboard at point blank Reliability: 9/10: The pin guide breaks every time I pull the pump back.  I need a fix for it.  EDIT: Problem solved, I bumped it back up 3 points because it works now. Innovation: 10/10: New trigger, New rotation mech, and pump action, all in a gun that performs very well. Overall: 9.3/10 FINAL SCORE: 9/10 Now even though this is a good gun, I still may have some gripes that were unrelated to what I scored on.  In this case, I have 1.  It is very difficult to put rubberbands on the gun or take them off.  But I still love it. Good night everybody.  And yes Knex_lover, I still have quite a bit of knex left over.  TD, if you wonder why I rated everything so high, it is because it deserves those high ratings, and I had little to complain about.

Technology Makes Cheap Drinking Water from Air

INTRODUCTION:   How can we best apply basic technology to help the underprivileged and/or disaster-hit countries like Haiti? Daily hygiene and nourishment are among the top needs for disaster ridden regions!  Simply put, no water means no hygiene. The Romans understood that over two millennia ago and created their complexly beautiful aqueduct networks for handling both fresh and wastewater! Other ingenious water systems like “air wells” have been found in the city of Theodosia (cf: discovered in 1900 by Zibold, see Zibold’s Collectors/Dehumidifiers) dating back to Greco-Roman times during the Byzantine Empire. These were strictly passive systems that naturally dehumidified air, collecting its potable water in underground basins. All air, even in relatively dry desert regions, will precipitate or release its natural water content (initially in the form of vapor) through condensation when it hits its dew-point temperature and below. That means you “chill” it to an appropriate level that is anywhere from 5F to 50F below its current air temperature, depending upon how much water content (relative humidity) it has locally absorbed. The condensation of the water vapor releases its internal latent heat (reheating the cooled air) which must be constantly dissipated (absorbed by something) in order for water formation to steadily continue. So how do we dissipate this resultant vapor-heat and chill our air without any infrastructure or electricity, in an underprivileged or disaster-ridden region? We simply bury a long cast-iron or any metallic drain-pipe sufficiently underground where the temperature of the earth is naturally held to a constant at around 45F to 55F. That’s our “free” chiller gift from nature. One end of the pipe, Figure-1,  sticks out of the ground to suck-in local outside hot air, and the other end dumps cooled dry air and water into an underground cistern where it gets collected and is piped to the surface to both exhaust the cooled dry air and connect to a water pump. We need a hand operated water pump to lift up the water above ground, and we need an electric fan to constantly pump air through the ground-chilled piping system. We can even force the cooled piped air to exhaust into a tent-like structure where it provides air conditioning as an added bonus, but this adds the penalty of both power and the increased fan size necessary to drive our required airflow further into an enclosure! While this concept is not “passive” (requiring electricity to work) like those clever Byzantine air-wells, it will produce much more potable water and within a smaller volume than those elegantly passive historic devices. The electricity for our fan power requirements can be produced by any one of four ways using either “active” or “passive” techniques: 1) An active playground or bike-pedaling-person or oxen-driven mechanism-generator, 2) A passive windmill generator, 3) A passive solar energy collection system that directly generates electricity, or 4) A passive thermo-electric system that directly generates electricity using the Peltier effect, operating solely on temperature differences between the cell’s top and bottom surface (we jury-rig the cool pipe and hot ambient air to contact separate sides of the cell). Depending upon how much water is needed, the required air volume plus pipe length and diameter, together with the fan will be sized accordingly. We can also configure groups of parallel fan-driven air pipes that are radially fed into the cistern. The sizing of this underground network depends upon the ambient air’s local average temperature and relative humidity (how much water gets absorbed into the air) plus buried pipe depth and effective underground temperatures achieved. The basic concept is one where we “wring” water from air at some given humidity content. The higher its relative humidity the more water is recovered from the air. The air-wringing process simply chills the air as it scrubs along the cooled internal pipe surface until it starts to rain inside the pipe from condensation onto its surface. The condensation is like the dew that forms on car windows, grass or any cooled surface in the early morning, before the sun comes out and evaporates the dew back into the heating air. A further bonus is that our dew-formed water is naturally distilled and very clean. It is potable water ready to drink without the need for additional sterilizing agents. Of course, we must make sure that the interior piping and cistern network is biologically cleansed before burying it underground. The hand pump with its 10 to 15 foot extended piping to reach the underground cistern must also be cleansed. The beauty of this constantly replenishable water supply is its convenient underground installation anywhere! After the in-ground installation, we have a virtual, partially passive, no moving parts, non-breakdown system containing above ground total access to all moving parts that could breakdown, namely the water pump and electric fan. Also, it is easily maintained, with few moving parts (water hand-pump and electric fan) and basically lacking any technical complexity which makes it ideal for technologically backward regions. The example below uses a relatively small industrial fan moving air at 1500 CFM (Cubic Feet per Minute) with a DC motor rated at 1kW. This fan together with our underground piping system will conservatively generate 12 GPH (Gallons Per Hour) of potable drinking water without need for any purification chemistry. Based on an average electrical cost of 14-cents per kWh (kilo-Watt hour), the typical commercial distillation of one gallon of drinking water costs roughly 35-cents as compared to our cost of only 1.2-cents. Furthermore, if we decide to go green and use solar energy for generating our water, it would effectively cost us nothing beyond the initial installation! USING A PSYCHROMETRIC CHART TO SIZE OUR WATER SUPPLY: The following gets a little technical and is only provided for those die-hards who are truly interested in how the science works. Those non-technically schooled may skip this part and not miss the basic concept. Figure-2 shows a Psychrometric Chart for air. This chart summarizes some of the basic thermodynamic properties of air throughout its typical range of operating temperature. The chart uses six basic air properties that defines the physical chemistry of water evaporation into air:  (1) the enthalpy or total energy contained within a unit of air which is a combination of its internal and external energy, expressed as the amount of BTU-energy per unit mass of reference dry-air, (2) the specific volume or the ratio of a unit volume of local air to its mass of reference dry-air, (3) the humidity ratio or the amount (mass) of moisture in a local unit of air divided by its reference mass of dry-air, (4) the percent relative humidity per unit of local air, or the mass ratio (expressed in percentage form) of the partial pressure of water vapor in the air-water mixture to the saturated vapor pressure of water at those conditions (the relative humidity depends not only on air temperature but also on the pressure of the system of interest),  (5) the dry-bulb temperature or the locally measured air temperature, and (6) the wet-bulb temperature or saturation temperature which is the local air temperature experienced during constant water evaporation (a wet-bulb thermometer is typically used:   a thermometer that measures resultant temperature while wrapped in a water wet-gauze and spun to generate local air movement and max-evaporation)  1.0   The Process and A Sample Calculation Our Psychrometric Chart uses six thermodynamic properties that help to determine the amount of water available for extraction from the local ambient air as a function of its temperature, pressure and relative humidity.  Let’s assume the following local ambient conditions for the region we plan to construct our water system at:  (1) Typical daily air temperature Td = 106F and one atmosphere pressure assumed at sea-level, (2) Relative Humidity, RH = 55%, and (3) Typical underground temperature down at six feet is measured at Tu=55F (at 12ft. it drops to ~45F). This yields the following calculated results for obtaining a steady-state supply (changes at night) of water to fill the cistern:      1)      In our example, the “local” air (dry-bulb) temperature is Td=106F, at a relative humidity of RH= 55%.  Fig-2 indicates that the resultant Humidity Ratio is HR= 0.0253 Lbs-water/Lb-Dry-Air (intersection of Td=106F line and RH=55% line, then horizontal to HR value).  We then determine the “gulp” of air volume containing the HR Lbs-water which corresponds to the point of intersection of Td and RH. Interpolating on specific volume “mv” yields mv=14.7 ft3/Lb-Dry-Air (this value sets the optimum unit airflow for our given ambient conditions, and creates a ballpark pipe length to diameter ratio needed later). It represents the basic unit of air volume that will enter our underground pipe per given time, and ultimately defines the size of our fan and piping network. For increased water creation, multiples of this unit volume will scale up the additional amounts of water that can be collected. 2)      As the inlet air cools down to a temperature of Tu=55F, from contact with the relatively cold underground pipe, we follow the constant enthalpy line (red upward left-diagonal) from the intersection of Td and RH to its saturated air temperature condition of Ts= ~88F, which is its dew-point temperature where the corresponding local RH=100%.  At this temperature or under, the air precipitates and releases its moisture content, resulting in water condensation onto the pipe walls.  Since our air will chill to a final pipe temperature of Tu=~55F, we follow the RH=100% saturated curve (green) down to yield an HR=~0.009 Lbs-water/Lb-Dry-Air. This is how much water is left in the air when it gets to 55F.  Therefore for every pound of local outside air that enters the pipe, mw=0.0253 – 0.009 = 0.0163 pounds of absolute pure, distilled potable water precipitates onto the inside pipe wall (per pound of dry air that is cooled and dehydrated) to gravity-flow out the pipe exit and into the cistern. 3)      We now convert pounds of air per unit time into a unitized volumetric airflow that yields gallons of hygienically pure potable water production per unit time. For every Va=100 ft3 of local volumetric air movement per minute (CFM) through the pipe, which translates into ma=Va/mv= 100/14.7 = 6.8 lbs. of dry air per minute or 6.8 * 60 = 408 lbs. per hour (PPH), to yield a water-flow of mwf=ma * mw = 408 * 0.0163 = 6.65 PPH or 6.65/8.345 = 0.8 GPH of water.  An industrial fan rated at 1kW DC will typically move 1500 CFM at a pressure of 8-iwc, to continuously produce 15 * 0.8 = 12 GPH of pristine potable water. 4)      Not shown here are the design details of sizing our pipe, fan and solar collection system for electric power requirements using heat transfer principles coupled with a thermodynamic heat balance, and aerodynamic fan performance assessment. These details help to size the electric power generation requirements plus margin used to properly size a solar collector containing further margins for overcast days. The engineering involved here is straight forward but beyond the scope of the current project.

DarkOwlKnex's Project Update Three

I've been doing a lot of stuff the past week.  I have to memorize songs for band, do summer homework, yada, yada, yada.  But, as always, I've found time for K'nex, and this is what I've come up with.  If there's enough interest in any combination of these, I'll post accordingly. The first picture is of the 'collaboration project' I had with Dr. Richtofen.  X3  It really wasn't a collaboration...  It was really me looking back through Dr. Richtofen's many successful attempts at a non-shooting Walther PPK and trying to make them shoot.  When I was finished building, I realized something: there was no firing pin for the gun that would make sense; the red rod was too short (it didn't reach the end of the barrel) and the black rod was too long (it stuck out the end).  I could've used a red rod firing pin and jammed the bullets down the barrel, (it was a singleshot) but I thought better of it.  I'd say at least 50% credit goes to Dr. Richtofen for that project.  The second picture is just a random little pistol I made out of boredom after scrapping the PPK.  it was cute and compact, but the next day, after I woke up at three in the morning because I couldn't sleep, I had a revelation...   What if I used the type of trigger off of The Racker Rifle (link below) on a mag in the handle gun, and positioned it just perfectly as to have the trigger block behind the handle.  I'd then give it removable magazines like on Blue Mullet's K'nex Handle Removable Pistol (link below).  The last three pictures are the result of about an hours work so far; I may update again soon. (Oh, and the Elvis mouse pad is my Dads, not mine; my Dad's a big fan, obviously.) The Racker's The Racker Rifle: https://www.instructables.com/id/The-Racker-Rifle/ Blue Mullet's K'nex Handle Removable Pistol: https://www.instructables.com/community/Knex-Handle-removable-magazine-pistol/ Thanks for viewing! UPDATE:  The big pistol thing is now named George, and I have pictures of it completed structurally, and internally.  It is now in Pre-Beta. UPDATE/NOTE: The internals you see in the last picture won't work, sadly.  I've updated it so that it now functions.

New drums: Kick pedal question. Answered

Greetings! Background: My xmas 'from me to me' present was a Roland TD-9K electronic drum set.  I have a concern with the drum kick.  I think I have it set up properly and it's either a setup problem or a user/technique issue.  The instruction manual says you can adjust (insert list of a bajillion variables) and 'set it up how you like' basically, without explaining how each variable effects the end result. My problem:  The kick pedal is set up as per the instructions and occasionally (every few beats) double-taps.  The hits are extremely close together, and are hardly audible if you're not listening for them, but they do exist in the midi data. (i.e. 1/64th beat later) The hammer is physically bouncing and hitting twice, it's not just spurious noise or an oversensitive pickup.  The brain lcd has a What I can adjust: Technique:  If I move my foot a bit it changes the harmonic frequency of the hammer, and it can solve the problem, but sometimes my foot ends up back where the problem exists The pedal assembly: -Spring return tension -- more tension = ability to hit faster but more effort required, problem exists everywhere from full soft to full firm. -Hammer location - it's centered on the sensor per instructions, and strikes flat and square. I could move the pedal off to one side slightly, or change the effective length of the hammer so it hits higher or lower (would change the periodicity of the system). -Angle of the sensor - per instructions is set straight vertical. -Electronic filtering - I can tell the brain to ignore hits for a period after a given hit to eliminate the spurious hits, but this wrecks my ability to intentionally use techniques where fast double-hits are wanted -'Home' angle of the hammer -- the angular moment with which the hammer moves with each kick.  Setting this too far away tends to make it hit the top of my foot (quite painful), and too short means its hard to make it work. Other Thoughts: I play barefoot, should I have a set of drum shoes?  Would that make a difference? I want to use these also to play rock band thru the midi adapter (people report its fun) -- but the double-hits would seriously impair scoring ability, and I need a way to fix them!

Project TTD--XM8

Alright well I wanted to keep this relatively low but I keep pushing back the project so I thought I'd let you guys know that trauts and I are working on an XM8 with a lot of special treats. I'm kind of stuck in California without my knex (and a small tub and a half here that will do me no good. I did teach my little cousin about knex guns and showed him the Mini-er TDS though >_<) so I'll have to wait until Friday to give you anything. I also have to finish my official assault pistol. So far the XM8 is just a bunch of ideas and nothing is built yet. I'm actually not sure as trauts might have made part of it but I haven't heard from him for awhile so I doubt it. Well for my assault pistol I was planning on making my war weapon now that others have. Thank god I think we may have found the new side arm and new new sniper fad...although now we're going to have a lot of spiff and bbkwg copies. It will be an open mag blue rod fed gun. I gave it a little twist for originality--I angled the magazine. This way the ammo is put farther up for more power but now the mag acts as a hand guard and doesn't stick out. Honestly it does jam like every 5 shots or so on average. I have yet to perfect it as I only started the night before I was leaving for CA. I should be making different versions of it like a larger one with a stock and yellows for ammo and then a smaller one maybe with a slide or something for whites. Anyways for the main project trauts and I are making an XM8 with a couple different features. Some things we're hoping to accomplish. *Similar charging handle- You'll be able to cock the weapon by pulling back a lever on top under the carrying handle. *Removable mag- Once again another one of my favorite accomplishments. *Interchangeable parts- The barrel/carrying handle and the back will be made to come off easily or at least without major mods to switch between the normal assault rifle and the compact version. *Hopefully we'll come up with an adjustable stock. *A grenade launcher for D splodies- Yup we're hoping to make a mini slingshot device in the form of a grenade launcher to attach under the XM8. Finally I have one last special feature pack that deserves more than a couple asterisks. We were hoping to save this as a surprise when we posted it but I might as well tell you. The gun will be part of a kit. It will be a war gun after all. The kit will include a belt/vest/ something to carry on you that will hold side arm, maybe an assault pistol, a couple of grenades most likely D Splodies so you can refill your grenade launcher, extra magazines, and finally a spot for your XM8. We'll try to hurry and post pictures with progress reports. I can't promise that we'll include every single one of these features but we are sure hoping to. So does this sound like a good Christmas gift?

Some random guns I never displayed on ibles

Alright, so I never really worried about it before, but I figured I'd show them now. These are a bunch of old weapons that I had at KI or KA but never bothered showing here. There's nothing huge that you've missed out on, but you might see something you never knew was done before. 1. This was in a video so you guys probably saw it, but I don't think I ever put pictures here. This is one of the first (don't know how many, if any, others there were) horizontal magazine guns. It loaded dark greys with green rods. I have tried making a more compact version for a while but I could never get one to load as reliably. 2. I guess this was the precursor to the BAW. I honestly forgot about it until now. Basically, before I figured out SK's removable magazine concept but after I learned how to make a decent magazine for yellows, I tried making a shelled-round gun with removable magazines. It had a really crude way of attaching but it worked. It fired very well, actually. But the shells didn't want to eject so you had to manually eject them. It was too crude of a weapon so I never kept working with it. I have tried making other shelled-round weapons but none have quite pleased me. 3. This is probably one of the more interesting ones. With my trigger concept that I loved so much, I tried making a bullpup bolt action. It worked I guess, but it had bad range because the trigger required I made a barrel up to it. I could've vastly improved this by using the PDR trigger, but I figured out, well one I didn't have the pieces and two the stock would be uncomfortably long if I did. 4. I don't know if I showed this here. I had thread on KI for it, though. It was my attempt at a Thompson M1A1. Bleh, it was very crude but I figured I'd show it anyways. 5. Here comes an assortment of assault pistols I worked on while at KA. I have notes written on them so apparently I brought them over here, but I don't remember where I may have displayed them, so I'll post them anyways. The first is a "revolver" using the redone concept by oompa on his revolver. 6. This one was a redo of the first one I mad a long time ago. Back before oodammo but after the TDS and all other side arms were being overdone, assault pistols were pretty much the new fad, and it became my obsession for a while to make the perfect one after seeing bitz's. This one fired blue rods. It's funny looking at it now, I could easily make one better in so many ways if I didn't care about using plain magazines. 7. This was my last one (not counting the revolver, which was done for kicks 'n' giggles) before oodammo. I tossed the blue rod magazine in favor of a removable, internal pusher darkgrey+green rod magazine. Lol, looking at this thing now...I was happy with the magazine at the time back when detachables weren't entirely common. So yeah, that's all I can find for now. You guys are welcome to dig around and see if you can't find something you've never shown before.

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.

Knex Revolver Pictures

***THIS IS NOT A PRIMARY WEAPON, BUT A SECONDARY. I am tired of people nagging me about it, it's a k'nex gun that shoots as far as any other powerful pistol, but the main thing I'm emphasizing here is QUICK RELOAD and RELIABILITY (no jams, mag pushers, or anything to get between you and your challenger). It's just a handgun that I slapped a stock on to look cool, so you can stop telling me that some kid's sniper is better or deconstruction round guns are things of the past because that's just your excuse to put me down. I'm not complaining, I'm just stating the obvious. 1. The whole gun, stock, clip, mech, and all. 2. This is with the clip on. 3. This is what it looks like when you take the clip off. 4. This is a front view of the clip the gun uses (I didn't show any empty clips, just take all the white rods off for an empty clip.) 5. And a side view of the clip this gun utilizes. 6. This is what it looks like when you hold it... The handle looks like crap compared to the TDS but actually is very comfy, as the white rods stick out around your fingers. 7. The retarted FPS angle that everyone seems to love. Stats (KI Template): Type: Revolver Weight: N/A Ammo Type: White or Green Rod Range: N/A* Firing Interval: 1.5 seconds Mag Capacity: 8 Rounds Mag Reload Time: 2.5 seconds *This one really depends. A newer white connector will not shoot as far as an older one since the older one will release the white rod easier. That being said, mine shoots about 20-30 feet with a single #64 rubber band at a slight upwards angle with an old connector. Not bad! Sadly, it does not auto-revolve, but there are no clumsy mag pushers poking at you, and while it takes longer to cock and shoot, the reload time is VERY fast, you disconnect a connector and connect a new one, so if you're fast I'd say 1-2 seconds. Also, if the annotations get in your way just click the white "i" at the top-left. EDIT: New double-cylinder. Slightly slower than reloading regular single-cylinders, but easier to carry around. 7. A picture of the gun with the double-cylinder. 8. The new clip, by itself. New Round: Mag Capacity: 16 Rounds Mag Reload Time: 2.7 seconds Yes, I know this design is relatively old. Yes, I know other people have done this. This is the first to feature a design specifically for detachable clips. This may not seem like much, but it reloads extremely fast, and with the double-cylinder design, can outlast any pistol in a firefight. Why? Well, for one, as opposed to loading in each bullet individually (if you use post-it notes they can clog up your gun no matter how you put them in), this comes in packs of eight and sixteen. Also, there are no rubber bands for the clips, so no jamming, no mag pushers, and no friction from the bullets. If you rush and slip up with a "regular" gun, you potentially have a broken clip, or bullets everywhere, or a jam. With this, the only punishment is a longer reload time. Also, while conventional knex gun clips have a lot of pieces, a single-cylinder clip has MORE ammo pieces than non-ammo pieces, and the double-cylinder clip has very few pieces as well. This means you can have more clips built, and the number of bullets you can hold expands exponentially! So again, while this couldn't fight soley against the SwagBoss, or the Knexsayer, or big knex guns, I would put my money on this above any other sidearm due to its reliability and the fact that its reload time is super short.

So...who is still here? Vet roll call + free concepts

Actually, I don't feel like asking for names specifically, as I don't remember everyone and some people would probably be offended if I forgot them. So, just reply to this topic if you've been here long enough that you've arguably established yourself a place in the community. I won't put any standards on that. Judge for yourself but be realistic if you wanna consider yourself a veteran. I want to know who is still here. I want to try kickstarting K'nex gunning back up again (ironic that it's me doing it) because I have plenty of ideas, fair amount of time, but little pieces. Basically I'm going to collaborate with whoever is still here and interested in my ideas. I'm hoping a decent rush of innovation will get old vets reinterested and perhaps inspire new K'nexers. If you're wanting to take on any of these projects below, let me know and I'll discuss with you them in full detail and provide whatever help I can. Otherwise, I'm leaving it to you to build them. -Improved shotgun concept. Look at Foofy's take on my concept and improve it further. I'm thinking of pump action and a large hopper. Make it bottom mounted so a higher powered weapon can be used on top -Controllable fully automatic sling gun. This would be revolutionary if we could get it to work. The potential is there, we just need to figure out how to unleash it. I've already talked enough about it, someone must be interested. -Pump action, pseudo semi auto turret. This would be somewhat complicated but still doable. Think of a gatling gun combined with the K-sayer. Each pump would cock and rotate a barrel. So you could then prepare a number of shots beforehand and then fire them all in succession. All of the above are potential war weapon candidates so I was figuring people would be more willing to give them a shot. If you're looking strictly for innovation or fun then: -Crossbow pistol. I always wanted to give it a shot but never could do it. Make it handlefed. It was going to be a candidate for my ultimate side arm back when I was still going through my TDS phase but now it would be purely for the sake of fun. -Automatic gun prop. I figured this might be interesting. Basically, make a gun that doesn't shoot but rather it ejects "shells" from the ejection port and fires either semi or fully automatically. I'm thinking you could make a rack and pinion system to drive the ejection port (which when opened would let the "shell" fly out) that's hooked up to a motor or a rubber band powered gear. It might not be as fun making something that doesn't fire but it'd be a challenge and something new. -Dual/triple stack magazine. Interestingly enough, this one is more challenging than it should be. Basically make a 3 layered magazine and then try to get it to feed into a single stack. Make it removable. The idea here is that it would have a larger capacity. It probably wouldn't be too practical, though. -Dual stockrail gun. Well, this could probably be a decent war weapon but it'd be somewhat complicated. It would combined several concepts into one gun. Make a rail gun with two rails in the stock of the weapon for extra strength with less length. Your choice of what it loads from. -Bullpup repeating sling. This has actually been made before. I know I got Jollex to make one at least. None of them seemed quite good enough, though. Add crossbow limbs and a magazine that accepts finned rounds and you've got yourself a pretty BA weapon. -Side folding stock. It's very doable, just annoying. If you could set up a hinge in a sixth layer that connects the stock and the gun, it wouldn't be much of a problem figuring out the rest. The problem is how to make that hinge. Eh, I'll come up with more. I'm regaining my memory. I kept most of my ideas in the dark and forgot about them. >_<

The Grand Knexpert War (IRPG)

Alright I was planning on posting this towards the end of the Grand Tournament but I thought I'd start right now because I have no homework and so I have nothing better to do =PAlright to start off this is an IRPG or Internet Role-Playing Game. It's just for fun and nothing is completely serious. While we won't fake battles or anything I figured we could start up something and possibly if I figure out a good way we could play some sort of good game. Maybe I could make up one giving each gun some stats and...blah blah blah I'll have to start a collaboration team so if you want to help...yeah.Ok so here is how it's going to work. First off I need to know everyone who wants to participate. All you're going to do is have fun as we go along with the topic. So yeah here is a list of all the people who are going to play along so that we are ready for the next steps-TheDunkis-Jollex-shadowninja31Ok well the Top 3 winners of the Grand Tournament will be Team captains. If we end up with a lot of participants then maybe even 4 or 5 teams may be established. If one of them doesn't want to be a team captain then it will be passed to the next runner-up but I would prefer that no more than one person does this. Maybe we should hold elections instead? Maybe they should be nominated because the best builder isn't always the best leader. After our Captains have been decided they will all starting with the highest winning person choose team members from the list in order. Please don't disclude anyone on the list or turn down those who do join. Believe me everyone has something to bring to the table. Once your teams are established you will then have to make a choice on what will be-Your team name-If you really wish your individual nicknames-I don't know. If you guys end up with a graphics artist then design a team flag-Establish ranks. Better the person better their rank. -Finally you'll decide your standard issue weapons. These will include: *One Side Arm (i.e. DMS, TDS) *Two compact secondary weapons (i.e. BBKWG, IaC's Assault pistol, basically any assault pistol to SMG sized weapon) *Two assault rifles (Well any mid sized repeater so like Trauts' Thompson, My AK-74, or as long as it's compact any one shot power weapon like the DD-27 if you want) *One Sniper Rifle (i.e. Mepain's Sniper, Gorkem's Sniper,...anything with sniper at the end of it maybe?) *One Support weapon (i.e. a rubber band gun. Which ever of the storms was a friggen' beast!) *One Explosive (i.e. IaC's War Bomb, Splodies) *One misc. weapons (i.e. Shot gun, Canno--Oh gees I do hope IaC ends up to be one of the captains so people are only fighting to be on the team and not fighting to be one his team after the captains are done fighting to have him on their team...)You may only choose weapons that belong to your team members so choose carefully. Maybe later if I establish some sort of forum for a full own game you might be able to make money and buy weapons from others yada yada.Ranks for now will be simple and will go as follow in order from lowest to highest powered.~Basic Troops-Private-Corporal-Sergeant~Commanding Officers~-Lieutenant-Captain (from now on this is officer rank and not the leader title)-General~Leaders~-If you really wish a Second-in-Command although this would most likely be a General-Leader-- You then get to choose your own title such as President, Emperor, etc.You then must choose a role. Uh check my war game thread to see all of them. I'll post them here later. You should then use the appropriate weapons associated with your role. This will be more important once again if I am able to come up with some sort of actual game.In the end however you team must develop and arsenal of perfect weapons. So who's up for it? Should be a fun way to pass the time. I might make a forum for the whole war to be located in. If enough people join. Then who knows it depends how much help I get on how fancy the forum turns out and if I could turn it into a permanent home or not.
