Needle Rifle

I need some help. I'm making a "needle rifle" (similar to a Halo needler, only green needles and it's a rifle) for a (working) prop. I made a few drawings of needle guns I could (or could not) make (depends on If I can work out a few kinks). The one I'm farthest in development on is the weapn seen on the bottom. This is a needle rifle. I want to mod a Nerf gun to shoot green darts (hopefully illuminated by glow in the dark, LED, etc...) and APPEAR like it's shooting needles (dyed plexiglass spikes) from a wheel that spins and "regrows" (not really) needles. I need a Nerf/Air Blasters/Air Zone dart gun that is motorized, rapid fire, and loads by inserting the individual darts into the gun when opened (no clips or ammo chains- although, good idea for a different needler gun design...). So here's my question- Which gun do I use, How do I integrate it into/around the "needle wheel" thing, and does anyone know how do make Nerf darts (suction cup/tagger/sonic/whatever works is great) actually light up? If it helps, I've got a zillion of these button cell batteries that seem to be the same diameter as a standard Nerf dart...Would an LED work? Also, if anyone has any ideas for a dart gun to use for the other guns in the drawing, it would be great if I could get some help with that as well.

Needle valve on the cheap?

I need a needle valve or similar to adjust some pressure with more or less precision. Problems I am facing with commercial solutions at the moment: Needs to withstand about 300psi max pressure, must survive contionous exposure to concentrated ammonia vapour. I already wasted too much money on stainless steel valves claiming to be chemical proof and capable of 6000psi only to find out they use seals that turn to goo in the ammonia vapour and fail. And since the stuff is not really healthy, not easy to get, I would prefer something safer. Real problem is also that the thing should be able to allow for good flow rates when opened fully. Modes of operation: During the active cycle ammonia vapour needs to pass through an opening as big as possible while after that the flow must be shut off. The reverse cycle needs to be adjustable from closed to fully open with great detail to control the flow rate. Current ways to compensate: With a ball valves and extra piping I could seperate the two cycles so I won't have to bother with tiny openings but I would prefer to use only a single connection. With a bypass around the needle valve this could be accomplished better but still looks ugly. Materials out of the question: Copper, brass, normal seals based on rubber, nitrile or similar. Questions: I know fully sealed in.line valves exist for LPG system and similar. Are any of these magnetic valves available for the use with ammonia? And if so: Can they be operated with a neodymium magnet instead of the coil? Even stainless steel valves rated for chemical use and high pressure fail quickly on the seals. Is there anything available that does not use soft seals but for example aluminium instead? Thinking spray pump here... One way ball valve systems like used in simple spray pumps are a great thing. With some aluminium tubing I was able to make a simple valve that with some more attention to detail might even work. But of course there no other way of moving the ball then to use a magnet and with sufficient back pressure even neodymium ones fail to get the ball in the open position and keep it there. Now getting this combine with a needle... If, instead of the ball, a magnet in a teflon shell is used on a spindle I could spin a magnet around the outside to turn the valve with great precision. Has anyone already designed such a thing or would I have to start from scratch here?

How can I make it look like someone is putting a needle in their arm? It's for a student film.

I know this is weird, but in one scene of this film, there is a close-up of someone shooting up heroin. Since we don't actually have the capability (nor desire) to show someone actually doing this, how can we fabricate a device that will look like the needle is being injected in the arm and squirts a little bit of blood out when the needle is removed? Any advice is greatly appreciated. Thanks

Dry Compass Needle Making

Hello.  I've been working on a project that I foolishly thought would be fairly simple.  It's a decorative compass, kind of.  The body was simple enough to make, but now I'm stuck on the needle.  I had researched the making of a permanent magnet and thought  the process was definitely do-able, but found out that with such a small piece of metal it's actually very difficult.  Then I did a little more research into compasses and learned that dry compasses do not work the same as wet compasses, mine is a dry compass.                 My question to all of you physicists and engineers is:  is it possible for someone to make a dry compass needle at home and, if so, how?                  I realize I could find a cheapish compass and pirate the needle, and will if I have to, but what fun is that?

DIY Circular knitting needles

I teach a knitting class at a federal penitentiary; while I've been able to get a lot of yarn donated, we still have very few needles (the only ones the inmates can use are wooden circular needles). I've been trying to make some myself from dowels and weed eater cord, but they look like c$?&, and the cord keeps coming out. If anyone has any ideas on how to make some, I would really appreciate it!

Stuck plunger help?

I recently got an antique syringe, complete with needles and all. It is in perfect working order, clean and rust free. The only problem is that the rubber plunger is stuck in the glass tube and won't dislodge. It has some rust like buildup around it, but it rinsed off the end easily. Can anyone help me get it out? ( I want to keep the original glass tube because I would like it to be complete and not have a new glass/ plexiglass tube) best answer to the solution that works.

need help bending/shaping a sewing needle into a spring-shape

Hello all!    I need help shaping existing sewing needles into spring shapes...and need to mass produce! I have an invention idea for a sewing needle, and after countless attempts at commissioning someone to manufacture for me, I have decided to do it myself. However, as I am a layman I have no idea how to get started!  I had created many prototypes by heating up sewing needles, then wrapping them around screws. I have tried many times to create a machine that could easily do this for me, however to no avail.  Another problem I have is that once the metal is heated and bent into shape, I need a way to possible polish and return the shine...   I have approached many shops worldwide from: sewing needle companies/ spring making companies, cnc, medical instruments, metal artists, aerospace, prototyping companies, 3d printing, the list goes on...  So now i'm back to square one...any help is appreciated, thanks !

Would this ionizer work?

I built an ionizer in an old metal ATX power supply case. My electricity is 230V 50Hz. It uses 22x 2.2nF capacitors and 22x 1N4007 diodes. The circuit is about this(with the activity indicator). I also added a small unregulated non-switching power supply for a fan that: cools the transformer forces air through the 5 needles. The ionisation current calculates to 5uA/needle. or 25uA total. Important (or so I think) details are bold.

Low friction "bearings"

For several of my projects I required some sort of bearing that would not only allow for a minimised free play but also very low friction.Before you get too exited: This is not a new type of bearing or anthing for heavy duty loads, not even for ongoing use without servicing.I found that even slightly heavier things rotated on makishift bearing far easier if the axle was verticall instead of horizontally.This gave me the idea to try a simple needle-bearing approach.This is how it goes:1. Grind and polish your axle to get a nice needle point - it must be perfectly centered!I prefer to do this with the axle in a fast spinning drill on a fine grinder.The polishing in a simlilar way, but please do not try it with a cloth in your hand on a spinning axle!2. The other part of the bearing is a screw or pin with a punch mark.I grinded and polished a punch for this so it has an angle of 60° and polished it to a mirror finnish.If alignment is of importance then of course the pin/screw must work for this purpose!If in doubt make it spind an use a pencil to get the true center.A drop of sewing machine oil and it spins nice and with very little friction.The key is to adjust the gap(s) between axle and punch mark to next to nothing.You don't want any pressure along the axle as you would "drill" a hole into your mounts.And you don't want it too loose to avoid wobble.I hope it might give you an idea for your next project.

What kind of cable or tube would you use to join 2 knitting needles of 2mm-3.5mm diameter? Answered

I am looking to create custom circular needles--each of which consists of 2 1-pointed needles connected by a smooth, flexible cable. This project is to provide access to knitting socks and certain other projects to a friend whose physical limitations make it impossible without the following: ~~~~ Circular knitting needles of which the metal needle portions are no less than 10" in length and between 2mm and 3.5mm in diameter. Cable length may be between 20cm-80cm depending on the project. ~~~~ What I'm stuck on is what kind of cable to use and how to attach said cable so that the yarn slides over it smoothly, going either way over the join. I can either cut the ends off of straight needles or use needles with double points--I thought the double pointed ones would allow the needle to slide into a hollow cable that could be meddled with so as to make a smooth join. it is possible that the larger needles are hollow and could have a cable inserted, but that would be very small. I am happy to entertain the idea of other material for the needles--it must be strong enough to do stitches without flexing. Bamboo has been tried and is out, given the length and diameter. The needles I have on hand are, as far as I know, made of steel. If I get anywhere, I'll post an 'Ible. Thanks in advance, Wicken

Removing Broken Pin from an RCA Jack

I recieved a free, working TV the other day. The only problem with it was the pin from an RCA video cable had broken off inside the socket. I didn't want to spend money on an RF modulator for my DVD Player, so I figured out a pretty solid way of getting the pin out. 1.) Find a needle 2.) On a hard surface, bend the very tip of the needle slightly so that it forms a tiny barb. 3.) heat the tip of the needle with a lighter until it glows red hot. 4.) stick the needle into the plastic core of the broken RCA pin 5.) wait a few seconds for it to cool 6.) pull the needle out, and the broken tip should follow!

'abstract' wood burning.

Not sure if this should be posted here, Outdoors or Square Pegs, but it's art related so I'll ask here. I once saw a how-to video, I am 90% sure is was on this site. but there is a chance it wasn't. I would like help finding it again. From what I remember, the person showing off had: a car battery, a long needle,  plank of wood and some chemical. the process I remember was (but may not be 100% accurate): 1. (s)he painted on a layer of chemical (or acids) on the wood 2. stabbed the needle on the wood 3. connected the battery to the needle 4. turned the battery on. it then made some elegant, fancy patterns, like a bare tree, or a lightning bolt. lots of 'branches' and paths were burned into the wood (without manual intervention. it was 'natral'). like a chemical reaction. if anyone has the name of this technique, or a video/instructable/guide, I would really appreciate a link. Thank! EDIT: solution found: it's called "Fractal Woodburning" (go on youtube for some videos). I should have known, I love fractials! you need: saline wood needles and a high-voltage power source. and patience.

Electric Gramophone?

I've just had an idea for making an mp3 player disguised as an old gramophone, to be used as a set piece/source of music for busking. Problem is, I can't figure out how to pull off some of the details of making it... Heres the idea as it stands: Have an old gramophone that appears to be playing music from a record, but is actually playing music from an Mp3 player. I figure you could interrupt the signal from the needle to the amplifier without to much trouble, as you'd still need the needle there to make it move along the record as it 'plays'. It also shouldn't be too hard to hide a speaker in the trumpet or even embed it into the side of the gramophone. In an ideal world, it would also be great to have some general controls on the back, to select play lists and the like, and that's probably achievable my attaching it to a standard mp3 player. The tricky bit is that I want to get it to play when the needle is placed on the record, and stop when the record finishes, ultimately with a digital replica of the scratch sound that you get at the end of an old record. Does anyone have any ideas on how to go about this part? because I'm absolutely stumped... is it possible that the answer lies somewhere in using the movement of the needle-arm to complete a circuit while in certain positions? Any thoughts, help, ideas or suggestions would be appreciated :) .

Scared of shots? Cough!

The Claim: Coughing Can Blunt the Pain of a Doctor’s Needle By ANAHAD O’CONNOR Published: January 25, 2010 THE FACTS Sometimes there are no words that can comfort a patient who fears an injection or the drawing of blood. But there may be one cheap and easy way to ease the needle’s sting. In the medical literature, it is known as the cough trick. Patients cough moderately just before a shot and then once during it. How this works is unclear. It could simply be a matter of distraction. Or, as a report in the journal BMJ pointed out, it may have something to do with a brief, cough-induced rise in blood pressure that reduces the perception of pain. Whatever the mechanism, studies have found intriguing evidence. Two were conducted in 2004, including one three-week study in which doctors measured variables like pain intensity, hand withdrawal and palm sweating as subjects had intravenous needles inserted in their hands — on one occasion while coughing, and on another with no coughing. Coughing, they found, reduced the pain. In another study, published this month in the journal Pediatrics, scientists at the Mayo Clinic tried the coughing trick on 68 children, ages 4 to 11, receiving immunizations. They found that it eased pain in Hispanic and white children, but not in black children — a finding they could not explain. And like any method, it has its obvious flaws: coughing too vigorously, for example, could cause doctors to miss their mark. THE BOTTOM LINE Studies suggest that a moderate cough during an injection may forestall pain. Pretty neat.  Might be a good trick to teach kids so they don't develop phobias.

Could someone tell me, how to run this motor (picture)???

Hello ... on the picture you can see a motor, that has 4 pins. I would like to make it run, but I don't know how. I don't know, if it's a brushless or brushed motor. There are no number, no part number ... and I think = I'm not sure, there is no magnet as well (I made a test with needle, but it didn't attract the needle). In my poor knowledge ... normal brushed motor has 2 pins, and all the brushless I saw, had 3 pins. but  I never saw a 4 pin motor. Any ideas ??? Thank you (in advance) for your help.

Really small analog gauge controlled by simple circuit

I'm looking to make a steampunk version of dr who's sonic screwdriver with some LEDs, a tiny recording module for the sound, and I also wanted a little analog gauge with a needle that would activate when the button was pushed. It doesn't have to actually measure anything, I just want the needle to move in some way. i found a little voltmeter on sparkfun that I could probably repurpose, but it's 2x2 inches which is a little bigger than I wanted.  I'm looking for something about half that size. Does anyone know of anything that would fit the description, or a way I could fake it?
