sprinkler valve and blow gun valve? Answered

Hello i am planing on making an air gun, but Im a little confused. my first question is that what is the best type of sprinkler valve to use (brand and size)? my barrel is 1/2" and air chamber is 1'. My second question is do they make a battery operated sprinkler valve, so i can just hook a electronic switch to it? if so what brand? my third is why is the blow gun valve necessary? thank you those who post answers.

Coil Gun

HiI am planning to build a small (length about 15 cm) portable coil gun. There are some really good intructables out there. (I still don't have enough knowledge of how to build this thing) I found this site to be pretty interesting. http://www.jeffhove.com/robots/coilgunhowto.html How can I make a powerful coil gun like that with capacitors (not that whole blob of camera stuff)? I am hoping that it could be rechargeable, perhaps by a USB connector (5V). But that would not last long right? So I guess by adding some batteries would help. Trying to get this coil gun to the smallest size with a powerful blow. By the way, there is something called EMF that affects the system?Thanks

Non lethal poison blow darts???

Non lethal poison blow darts.? I was thinking about making blow darts then the topic struck me, could common natural non lethal poisons or toxins be used in blow darts. This sounds a bit vague, so heres and example: you take poison ivy leaves and either wipe the darts on the leaves or grind up the leaves then rub darts in the mix. Would this work, how effective would this be?. I am not planning on even attempting to try this, this is for informational purposes

Air cannon/spud gun trigger Answered

I've opted to go for the modded sprinkler valve trigger. My questions are thus: Where can I find the required 'blow gun'? What is the 'blow gun' for when not killing potatoes? Will the valve reseal if the trigger is released before all the pressure in the tank is gone? So, can you fire more than once before pumping up again?

How do you make a complicated, fully automatic pen gun that fires BB's?

     Looking from all pen gun instructables, none is trully fully automatic. I came up with the idea of turning a small crank to pull the firing mechanism then release repeatedly. It's kinda' like a gatling gun. But at my disposal are a few HBW pens and no available nor acquirable Bic pens which are wide enough for BB's. I know how to widen HBW pens for BB's but then it's labor intensive. I need another solution. And by the way, people keep talking about loading up a pen with a gravity feed then blowing as hard as I can through the input hole 2, and BB's would spray out the business end. It appears everything here is too simple, so title changed! Don't give me the previous described method.

Gas connections

Hey Guys.  I have a laser tag project that I am making. Now I want to put high pressure air recoil on it. With the HPA being in the magazine and the recoil being a blow back valve in the gun.

Can build a coil gun using Direct-on-line technique?

Hello,I'm trying to build a coil gun and am stuck with this problem.....the gun I'm trying to build will be using a 5200mAh 22.2V 25C battery as source and a 16swg wire for coil in series with a N-channel power MOSFET (IRLR7843) as a switch. I'm using a 0.2ohm resistor to draw 110A current from the battery....but the problem is the resistor I'm is not capable of handling this huge amount of current it just blows up. I've looked for other alternatives but the problem there is with the size, which is not feasible in my case. so now I'm looking for a suggestion for some kind of resistor that comes in a small size which can handle this current and possibly has managed to stay out of my sigth.....or if I can go ahead with the DOL and eliminating the use of resistor entirely and connecting the coil directly to the battery( I know that might be foolish tho)

Vice CKG Bolt Action Rifle

I haven't posted anything for a few months, and I decided to begin work on something that would blow everyone away.  My goal was to create the most efficient, most power, most versatile mag fed knex rifle ever.  I discovered a way to do that when I came up with the Bullet Transfer System (BTS) that you saw in my BTPA pump action rifle.  However, the BTPA had a several drawbacks.  The first was the size of it.  It was just way too big.  Second was that the ammo it shot was connector ammo, and would start spinning out very quickly.  Last was that the ram barely had any time to accelerate,  as the bullet was placed right above the handle.  I suddenly thought of a design that would solve these problems, quickly drew them out, and began work.  The result was the most efficient, versatile, and powerful mag fed gun ever made, the Vice CKG.  CKG stands for Compact Knex Gun, and I am truly proud if it.  The trigger is a variation of Zak's so I give him credit for that.  So exactly how efficient is this gun?  I was able to get 60+ feet with a string of two #64s with the long range round.  The yellow rods get around 50 feet, only because they spin out after a while, but with two #64s unsharpened yellows can go right through a box from a few feet away.  What's the secret to this incredible efficiency?  First off, the firing pin is a grey rod+a gray connector long, giving it that extra room to accelerate.  Second, the trigger is as far back as possible.  Third, the rods are placed as far away from the ram, giving it time to accelerate.  Finally, the BTS allows the bullet to stay in place with nearly no contact between the bullet and the gun.   THIS IS THE MOST POWERFUL, EFFICIENT, AND VERSATILE MAG FED GUN OUT THERE. (I know that statement may sound a little bold, but I am very confident in saying it) Pros 60+ feet range single shot with two #64s 50 feet range with yellows with two #64s Extremely versatile (perfect for long and close range) Looks great 15 yellow rod mag capacity You will dominate the battlefield Cons Reload time (for me anyways)   This video is a little out of date, I have made some upgrades since it was made/

Thing is, I need to find a relay that won't blow up from this, so what kind of amperage will I be getting sending this through a coil?

What's Your Favorite Clint Eastwood Movie?

What's your favorite Clint Eastwood movie? The gun pointing, back talking man who I loved it when he goes "Go ahead punk...make my day" or "I know whatcha thinkin'. Did he fire 6 shots or did he fire 5 shots. Through all this excitement even I lost track myeslf. This is a 44 magnum, the strongest pistol in the world-- and can blow your head clean off. Your gotta ask yourself: do I feel lucky? Well, do ya punk." What's your favorite Clint Eastwood movie?

SRV-3 The Concept Review with JBG's SRV-3

Hello fellow iblers’! I’m JonnyBGood and today I decided to post a review of the SRV3 concept. Be sure to note that this is not KILLERK’s official version but a close knock-off. I did not use the same bands or the exactly same mech. I also did not make side covers or the monopod so don’t judge his version based on my model. I also never shot it outdoors so ranges are a complete guess, but I will say KILLERK’s ranges are very believable since I witnessed them at Knex War 2013. So now with all that gibberish out of the way what exactly am I reviewing? Well I’m reviewing the concept, the ratchet mech, trigger mech, and any other part that contributes to the guns function and ergonomics. Okay so now let’s start with the ratchet… Ratchet- After the first use of the gun, I couldn’t imagine trying to load the gun without it. I did try loading it without using it and ended up spontaneous launching it in random directions, something you don’t want to happen with a gun this powerful. (Luckily the wall I hit was cement) The ratchet concept is really what makes the gun usable for people of any age, height or strength so I definitely think KILLERK did a great job designing this feature. Trigger- Well I willingly admit this part is the most different from KILLERK’s version, but it does rely on the same concept of the round being held in by a clamping force. I was actually the most concerned about how this would work because to me holding back a force that could send a yellow rod through a door with a clamp didn’t quite make sense to me.  I will saw after building it I now don’t doubt the clamps capability to hold the round, and now it also makes sense as to why he used a clamp. The clamp trigger mech allows for a very light trigger pull due to the pivot point being so close to the ammo, so the slightest pull moves the clamp up.  SRV-3 trigger is definitely one of those surprising concepts, being that the most powerful gun on instructible’s has one of the lightest trigger pulls I have ever used. Random other things- The ratchet and trigger were the two concepts which to me stood out the most for the SRV-3 concept but there are many other things about the gun which I will cover here. The Handle- So surprisingly enough it is actually pretty comfy, and it’s mainly built to hold the heaviest knex gun I have ever built. On the other hand, I wouldn’t try lifting this gun by just the handle, but why would you? You are definitely not going to akimbo these things unless maybe the handles were moved more toward the front of the gun, and then held like an RPG, but again why would you even want to akimbo or hold it with one hand? It’s a sniper rifle! The Dimensions and some other random things- Alright I bring dimensions up here because I think it’s one thing to see pictures and another to actually know how big this is. If you stand it on end it’s about six feet tall and it’s a yellow rod wide, so ten layers wide. (if you filled in the center which you would not do).  Again as I ranted about earlier this is what makes this gun so heavy but it’s required for the amount of power it’s capable of. You would also add another two layers if you wanted to make it more presentable so it could be 12 layers wide if you want it to be. Another thing that I noticed on my version was that the gun bows toward the end.  Granted I’m not sure as to why or if I was missing a support somewhere but it wasn’t a problem just something I noticed. The only other thing I was planning on reviewing the accuracy but if anything was relevant it is that I suck at shooting accurately! XD I can’t even shoot guns I build accurately so, a guy who is much better at creating coverfire, will not be giving an accuracy score. I will say the sights allowed me to shoot a 8 ½ by 11 sheet of paper from ten to twenty feet relatively easily, so they do help. In conclusion I would recommend you build the SRV-3 if you have the pieces for it. I would especially recommend it if you haven’t built one of KILLERK’S SR’s before because the power will blow you away. It is deffinitlly the king of the slingshot platform for now and probably until an SRV-4.   ( I apologize for the poor picture quality but it would not fit in my normal picture taking spot and there's still too much snow outside for outdoor pictures. Sorry!)

Rebuild and reuse?

I was just thinking today. I want to get a soldering gun with a desoldering bulb or some kind of device to suck up solder so I can remove parts. I have nearly heaps of old computer motherboards, video cards, ram, and all sort of other things taking up space. And I'm not talking like pentium 3 or old p4 parts, more like P1 and even a few tandy and 486 parts kicking around. I've seen people making earrings and wreaths out of these old parts, but I'm thinking more practical, like what could I be building out of these components. I've never really gotten into things like pic programming and building things on bread boards, however I do have the know how to operate a soldering gun and I wanna get into these things. Could someone point me in the right direction or point me to a forum at least?? It'd be greatly appreciated because I really need a new hobby to do in my spare time instead of blowing my amps.
