AR-4 v4

I know I posted this on KI about a month ago but there are people who don't look on KI, so I thought I'd re-post it here for convenience (to you, not to me) I couldn't think of a better name for this gun anyways, don't call me out on it: http://www.youtube.com/watch?v=OtPvzJMSz18

Advanced AR Drone?

I've been thinking and have a good understanding of physics, and am planning on possible making an AR Drone similar to the Parrot, however capable of carrying a load and perhaps a small compact paintball gun. Can anyone else say awesome?

AR-4 v3 mods.

Ok, so I made some mods to my AR-4 v3. There are 3 major mods, a couple of other minor cosmetic mods, and one performance mod. Picture 2- minor stock mod. This mod allows people to extend their stocks to make it longer. Picture 3- New hopper based off of Killerboy's removable mags. Major mod. By using his hopper as a fixed mag, It now allows me to hold 9 yellow rods, which is pretty big. It does jam, but rarely. The rounds will all stay in the hopper if you vigorously shake it, and you can remove the rounds pretty easily. Picture 4- Minor trigger mod. All it is is replacing the hinge with 2 Y connectors, a white rod, and a purple one slot connector. Picture 5- Scope mod. This connects the scope to the top of the gun, making it a better hand grip for carrying. Picture 6- Yet another scope mod. This mod was made to adapt to the new fake barrel, which was filled up instead of only the middle row having the orange connectors. Picture 7- Mod to the bottom of the gun. The last one was just having blue rods, this one fills it up with connectors. Picture 8- Foregrip mod. This is the second of the 3 major mods. I did away with the bipod and modded the bottom to have a new grip. Mainly a comfort mod. Picture 9- Barrel mod. The last major mod. This mod was made after several people noted that the ammo needed some 'Help' to get into the barrel. I basically just filled in the hollow area where the ammo would jump from the hopper to the barrel, so you dont have to stick your finger in. Picture taken from top of gun. That stuff above it is what you connect the scope to.

AR-4 Commando v3-NOW POSTED

Posted!Do you think this gun makes the AR-4 v2 look like a noob's toy? plz answer!This is a new bolt-action knex assault rifle I made. It shoots Yellow rods. This gun is the first bolt action to my knowledge that doesnt use modded part.For those of you who dont think it is true bolt action, to shoot the gun, you have to pull the ram/bolt back, then push the bolt back while leaving the ram pulled back.STATS-Bolt-action-True trigger-includes bipod (foldable)-tight looks-includes scope-6 round hopper-30-40 foot range (one rubberband doubled up)-Safety (new)EDIT- I have put tape on the part of the bolt that pulls the firing pin back, and it gets an increased range. the tape straightens the parts that hold the bolt, decreasing friction.This started out as one of my failed projects, I made it before the jackal and showed it to ajleece and some others. The original one had a bottom loading removable mag, shot blue rods 5 feet. I took it apart to make my jackal, and then I got the idea to make it a true bolt action.I was not trying to compete with the ZKAR, I was just trying to make my AR-4 v3 work.Here is a video of me firing it on youtube:

AR-4 v3 VS ZKAR V2 Round 2 (Personal experience)

After reading knexgeek's review, I decided to build the ZKAR to see what my AR-4 was being compared against.  I can't do a side-by-side comparison because I ran out of green rods.  Anyways, Here are the advantages of both guns over the other. ZKAR advantages over AR-4 v3: -ROF -Size (smaller, but weirdly uses more parts than the AR-4) -Comfort -Better trigger -Yes, I guess it does have a nice, clean design AR-4 v3 advantages over ZKAR: -Range (gets a slightly better range than ZKAR with an equal amount of bands, around 5 feet better) -Reload (While you can easily slip rods in at regular intervals on the AR-4, I find it a bit difficult to keep the ammo in before I put the pusher in on the ZKAR) -Sturdier than ZKAR (I find that some parts on the ZKAR break after heavy use, while the AR-4 v3 is just fine) -Farther pin pull Now both guns have their flaws, Let's just list some of them: ZKAR flaws: - The back wall on the mag closest to the trigger can break off.  However, it's a good note that the bolt always touches that back wall so I guess it evens out.  It has only broken once when test firing. - If you somehow pull the bolt back and push it forward twice, you find that it can jam and it's a pain to get it fixed. - Sometimes the bolt breaks.  However, to be fair, it only broke during ROF tests. AR-4 v3 flaws: - Can't be loaded upside down (I don't see this as a major problem, and you can shoot the gun upside down, but idunno why you would wanna) - Sometimes the bolt doesn't go into the chamber without "Help", but then you can just stick your finger in. - A few times, the ammo completely misses the bullet lock.  This is rare though. So I guess that's my comparison.  I do like the ZKAR and it does live up to it's rep, but I think it's all an even playing field with each gun having it's own uses on the field. While I'm at it, here's a ZKAR v2 review (I know there is another ZKAR review, but that was for the first version) Body structure: Stock: 9/10.  Why: very sturdy and comfy Handle: 7/10 Why: Sometimes pinches your hand Trigger: 10/10 Why: Very sturdy and original Body: 9/10 Why: sturdy, but a bit hard to build Mag: 7/10 Why: Small chance that the rear mag wall will break off (that has only happened once to be fair) Bolt: 7/10 Why: Works, but the bottom part that pushes the ammo up to the barrel can break after heavy use. Overall: 8.1/10 Performance: Range: 9/10  Why: 55-60 feet with 2 bands Accuracy: 8/10 Why: Accurate at close quarters, not so much at longer ranges Power: 8/10 Why: puts huge dents in cardboard Reliability: 7/10 Why: Sometimes the bolt catches on the ammo being loaded up in the barrel and causes jams.  This is rare and has only happened to me twice.  Everything else is fine. Overall: 8/10 Final score: 8.1/10 Nice gun zak!

AR-4 Commando v3: Review

Here is the review for the AR-4 Commando v3 by DJ Radio.What to expect:Innovation: 10/10 Very innovative new rail system, and loading design. Strength: 9/10 He did a very good job of making it strong with the amount of pieces used.Range: 7/10 It is not much better than any other ram rod. But I got an average of about 20 feet.Looks: 8/10 I think it looks ok. It is by far his best looking gun.Parts: 9/10 uses about 1000 pieces. So I would call it low piece. Handle: 7/10 the handle is a little too small for me but it might work for others.Stock: 9/10 very sturdy Barrel: 8/10 Innovative. and it has a low friction barrel. Fake barrel: 7/10 bullets get stuck occasionally. Magazine: 7/10 new and innovative but jams occasionally Extras. Bipod:8/10 not the best but it holds up the gun.scope:8/10 It works good.At the end: I would give the gun 8/10.Here is the link to the gun. https://www.instructables.com/id/AR-4-Commando-v3/Thanks for reading.

Question about electrical safety for a project with a 60V Power Supply and a Nema 34 Motor?

Hi Instructables Community,I'm working on a project with someone where we are making a VR game that uses a stationary exercise for interaction. For example, if you turn up a hill in the game while exploring a map, it gets harder to pedal. The resistance on the exercise bike is controlled by turning a knob.The knob just controls a brake-like device that adds friction to the flywheel. We're just going to use a stepper motor to control the knob with a belt. We, somewhat unscientifically, compared the torque required to turn the knob on the bike to how much torque Nema 17 and Nema 23 motors require to pull parts of a 3D printer back and forth and decided we probably need to use the bigger NEMA 34 motor. The stepper motor driver and motor we are going to require a 50V or 60V, 5A DC power supply. The motor will need to be attached to the frame of the bike near the resistance knob.This is the stepper motor and driver we are planning on using. This is the power supply we are planning on using.The stationary bike we are using is made of steel and very heavy and will be moved around a lot when people want to try it or move it out of the way. I'm a little worried that since the bike will be moved around a lot and since the motor will be connected to the bike, that if a wire got pinched or damaged it could lead to an electrocution hazard. How can I make the electronics on this project as safe and fool-proof as possible?My plan for safety right now is:Use a GFCI power adaptor to power the power supply (link)Keep the power supply and driver in a metal, grounded project enclosure (link)Ground the steel frame of the stationary bike.Keep the project enclosure fixed to the stand of the bike so that it moves with the bike when the bike is moved out of the way.Put the wires to the motor in some sort of heavy-duty insulation or conduit that's securely fixed to the frame to avoid any pulling/s shearing. Any advice/feedback/recommendations would be greatly appreciated.I don't have any photos of the set-up right now since this project is still in the planning stage.

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!!!

SR Commando v1- NOW POSTED!

I have been hyping this gun up in the chatroom for a bit, so I got a pic today.This is A combo of my 2 best knex guns I ever built- The AR-4 Commando v2, and the Longbow v2. I made it mostly for the innovative ideas it brought, but i wanted to see if it was possible to combine the AR-4 v2 and Longbow v2.This gun uses an extremely reliable BRAND NEW sear system trigger which never misfires or jams, I thought of making a double-ratchet system and put it in a super modded Longbow handle. The stock Is an uber modded AR-4 commando stock. Same thing with the barrel.It is a single shot, but it can have a mag. Range is 40-50 feet (one rubbeband).the second pic is a close up of the mech.The only con I can think of atm is that this gun is sorta skeletony at the bottom. But its extremely sturdy neverthelessOk, I changed the name because I thought it would be less confusing and more appropriate.
