I have been saving pop bottle caps for a short time now. But with the amount of pop my wife and I drink I am going to have them coming out of my ears in no time. So anyone have any crafting ideas to do with pop bottle caps? One thing I thought of was to make a computer case out of them. But maybe I have watched that video of the guy making an 8-bit Zelda case out of wooden blocks too much.

So i want to make a coffee table/beer pong table. like this http://media.pongalong.com/images/bestbeerpongtables/BudLightBeerPongTable.jpg So it is going to be 3' x 8' and i want to have 2 sets of legs underneath of it. A short set for the coffee table and another set that are taller to use it as a beer pong table, or just a regular table for that matter. So my main question is where can i find locking hinges for the Table legs? I have found some, but don't seem to be very heavy duty. I want them to be able to lock the legs in the horizontal position to hide them under the table while the other legs are locked in the vertical position. Also does anybody have any suggestions for cheap fiberglass or resin to coat the bottle caps. Didn't realize how expensive the stuff is. Cheaper is better.

Very long story short, I'm making a BB gun. I've got the basic ideas and mechanics almost done, its just a matter of making it work and materials. One of my big problems right now is that the gun will be .177, but it's going to mimic the look of an old flint or caplock muzzleloading pistol, which ranged from .36 all the way up to .80 in the largest ones. Obviously the barrel will have to be concealed within a larger, false barrel. My problem is making the real barrel attach securely without negatively affecting accuracy because it's off center. fitting the breech of the real barrel with a nut or a thread insert has crossed my mind, but I'm not sure if It will be enough. pictured are some examples of caplocks so you have an idea of what the finished product is planned to look like

I wanted to make a cap gun that would fire flash cotton. I found a toy cap gun with individual chambers to each cap. I added copper tubes to load the flash cotton & fire out the muzzle of the gun. It didn't work. The first click & all the cotton I loaded went off at once. Anyone know how to modified a toy cap gun to accept individual cap shells, or how to make shells you can put caps in?

Ok.... I have literally exhausted every avenue I can. All I can find are already done bottle cap beads and their finished jewelry. NO WHERE have I found the instructions on how to actually make the beads themselves. I need help. This is driving me INSANE! Basically you take to bottle caps(and MAYBE you round em out with a ball peen hammer) Then you weld? glue? them together and drill holes thru them. I have hundreds and hundreds of bottle caps for this project. All I need are the instructions to do this project. I am begging anyone out there who knows of, or has made these please, please... Write me here, communicate with me telepathically.... Something.. Anything! I am begging my fellow Instructians for assistance! Thank you in advance!! Johana P.S. I am posting a picture of what the finished things look like. Some have the wavy edges and some don't I don't care if they have one of the other. I just need to make these guys!!

You know those caps they had back in the 20s and 30s, the ones where the top would kinda hang out over the bill, kinda like the one in the pic, but not exactly. Well, does anybody know how to make one? If you can make one, then please post an I'ble, 'cause I've been needing one for a while and can't find any. By the way, the one on the right is sideways, incase of any confusion. I was kicked off of Yahoo! Answers today. I never realized how much of a slave I was to them. You Instructables people are smarter. I am leaving Yahoo! I have switched over to my Gmail account, and I'm happy. I've asked about this cap on Yahoo, and never got an answer. But you guys/gals are smarter and craftier, and I can actually go a good while on here without calling someone an idiot, unlike Yahoo. Well, have fun crocheting, knitting or sewing a cap from the long ago(if you'd like to).

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

Hello all, this'd be the first post i've ever made, and may be in the wrong place....... edit- i guess it was in the wrong place, since no one replied.... so i'll try here.... i'm tryin to make a cap bank from 30+ flash cameras (possible? possible outputs? how do i calculate that?) and i have some question/problems. is it possible to take a bank like the above and use as a spot welder? if so, how would i trigger the spark without the trigger becoming the spark gap? another possible use i have for it is a rail gun...... theoretically, if counter evidence isn't provided by all of you much more tech inclined ibblers a second concern is that the caps come in at least three different micro farad ratings. would one explode if it's rating is lower than the higher ones? (the ratings are between 80ish to 150 ish (don't remember)) i rather need the weilder for a possible steampunk project that i just bought a bunch of metal junk for....(knowing me though, i'll never get around to doing it....)

I havetwo 680 uF capacitors, rated for 200 volts.. And I want to use a disposable camera charger to charge them both. The camera charger stops at 300 something volts, and when I wire them up in series, I get 400 volts, right?.. I want to charge them and discharge them into a coil of wire to launch a projectile at a fair velocity. , I can work with up to 10k wraps of wire, and i have only two capacitors and a major one.. First 2: 680 uF 200v 680 uF 200v Major one: 180 uF 400v Now I imagine I'd get more joules with the two smaller ones than the big one because of the microfarads, right? These specific type of capacitors are made from Elite, and are electrolytic I think, and I got the major one from a computer CRT monitor, and the two smaller ones from a computer power supply.... I also have a 3.3uF 50v capacitor. Now the question is: Can someone help me add these together to increase maximum joule output? I want to hook up the two 680 uF 200v capacitors in series to get a maximum voltage of 400. Then I want to add the major capacitor, which is 180 uF in parallel with the two other capacitors to increase microfarads, in this case, it'd be: 680 680 + ------- = 680 (because they are in series) ------- + 180 = 860 I want two capacitors in series, and the major in parallel, increasing voltage to 400 volts, and the major capacitor doing nothing but adding capacitance (IF possible) Sorry, this is alot to ask for you guys to answer, If none of the above can work, What would work better, the two 680 uF's in series, or one big 180 uF 400 volt capacitor? I apologize if I cannnot explain my question properly.... it's very hard to understand capitance and series/parallel blah blah mumbo jumbo. Thank you.

I recently got a few of the 3000 farad 2.7 boost caps from electronic goldmine. I have a quick question about charging them. Applying a higher than rated voltage before the capacitor is charged all the way would be fine, right? The voltage drop should cause the source voltage to approach 0, thusly below the 2.7 volt rating. As an extreme example, lets say you simply hooked up a 9 volt battery to it. Since the battery can only supply like 200mA, the voltage drops to nearly 0 as the capacitor appears to be a dead short. The dielectric (or ion exchange or napheon membrane or whatever it is in a ultracap, lol) should be fine, correct? My main goal is to later hook up one or two of these for a regenerative brake system of something like a small gokart or bike or something. Stopping at 30mph is like (assuming 200kg total mass) 20k joules, and each one can hold about 10k joules, and assuming a max efficiency of like 30 or 40% (I think itd be much lower, though), these capacitors could brake a gokart going fairly several times without having to be discharged inbetween cycled (but of course they would be). For braking, could these essentially be hooked up directly (of course with pwm, and other things, but in essence:) to the motor with a little protection circuitry to prevent overcharging the capacitors? Or would the higher voltage instantly puncture and destroy the boostcap?

Is there such a thing as a switch that is touch sensitive so just a tap will activate it. I want to make a lamp out of an empty glass coke bottle and i want to be able to touch the cap to activate it. Im looking for a small piece of silver metal that will match the cap so i can place it on top, OR a way to make the actual cap the switch. Thanks!

Hey guys, recently I scored a Samsung 943nw monitor from my friend who says it's broken. So i thought, why not try repair it? Upon opening the lcd monitor up, I can see that the caps were bulging, samwha brand. The infected caps were three 25v 820µF and two 10v 1000µF. I went and sourced the caps from a couple of devices (a modem, and a power supply) When I turned the lcd on, the led was blinking. After the repair(with my crappy soldering skills), the monitor turned on, but not the backlight. I figured that the cc backlight inverter was spoiled. Then, after a probing at the components, I reset the monitor in hopes that the inverter would work. Instead, now the monitor showed no signs of life. Probing again showed that the 5v rail was 8.45v and 15v rail was 4.5v and 3.3v was ov. I still can't find the problem after hours of searching. (and a fatal electrocution from the mains input cap). Could it be my bad soldering, parts or some transistor problem? DId I also accidentally fry the image processing module?

I bought a new 2 cycle lawn mower in the spring. It worked fine, then it starting dying. I unscrewed the gas cap screwed it back on. It worked fine for a few turns. Died again. Figured cap needed to be vented. Now it dies continuously. Need some suggestions.

Hey guys, I am currently building my first coilgun, first of all, the components: Charging: Disposable camera circuit x 2 2 x D cell batteries Capacitors: 2 x 1200uF 200V 2 x 680uF 200v 2 x 300uF 200V 1 x unknown (attached to camera circuit with no info) Switch: 250V @ 15A - 6 pole toggle (I will upgrade to some for of solid state when I have the money) Now, because I have two of each capacitor I have put one of each into a parallel bank, giving me 2 cap banks with one of each cap, I then connected the two banks in series, I have not done a lot of maths yet which I think I should but I was hoping that would give me 400v which seems to be average. The problem is, it is only charging to 340v tops, I think that may be due to the camera circuits being wired incorrectly. I have the two batteries in series, both charging both of the circuits, then the circuits both charge the caps, the + and - outputs meeting on the caps, am I doing that wrong? Also, does having 300uF caps in series with 1200uF caps hinder the bigger ones? Would I be better of with just the 1200uF and 680uF, or maybe even just the 2 1200uF in series? should I also leave the small cap on the circuit or take that off? Thanks in advance guys, any help would be greatly appreciated. I am having a lot of fun with this project and while I wouldnt like to be on the other end, it is still not as powerful as I would like, even for it's small size.

So, i have been working on making a coil gun. and for that, i need a cap bank. so i took twenty caps from cameras and put them in parallel. it was a lot of capacitors. i went to go charge them up late at night and believe me, that was a big mistake. i flip the switch and started waiting for the light to come on. until, i cap exploded. i couldn't hear for almost 15 seconds. it scared the crap out of me, and i am sure that it would of hurt if i touched it. don't do this. i got in big trouble from my mommy.lol.

Anyone here know a thing or two about gun ammo? Anyway, I have just been wondering on exactly how primers worked. This is how I made mine. "Sorry if I seem like a lot of questions) The Cartriage is a section of a copper pipe, the bullet is made from a fishing weight, the propellant is match powder. Since match powder does not go off with impact,I made the primer from a thumbtack, a strip of tin(can), and a roll cap(those red paper things that explode when you hit them with a hammer). The cap and the match powder hold the thumb tack in place. The strip of tin holds the roll cap. When the thumbtack is struck, the thumtack hits the roll cap cuasing it to create a small explosion. When the roll cap explodes, it ignites the match powder around it. This larger secondary explosion is the one that propells the bullet forward. It works on homemade automatics, the only thing is that the catriage gets stuck sometimes, it produces A LOT of smoke, it takes around a half a second for the match powder to ignite and to propel the bullet forward, and after a while, a layer smelly brown tar begins to accumulate in the barrel. Is this a bit simmilar to how primers work?

Hello, I want to fill my beer bottle cap table in with clear resin and I am wondering how much resin i will need. I have done the math myself but I think I may be wrong. The table is 85"x36"x.25" (has trim up to the cap height) If i did the math correctly I will need 2 gallons of resin. I just want to confirm before I buy $120 worth of resin. The beer bottle caps are roughly 1"x1"x.25" and there are about 2300 of them. so what i did for math was 85x36 = 3060 (x .25) = 765. 765 / 12 = 63.75 square feet 1 gal of resin covers 32 square feet 2 gals needed correct? but then i tried to plug in how much space the caps take up and if i can get away with just 1 gal. so 2300x.25 = 575 square inches 575/12 =47.91 square feet 63.75-47.91 = 15.84 square feet which means 1 gal of resin would be plenty..... am i doing this math correct? thanks for the help!

I noticed that recently a lot of users are looking on information on how to charge capacitor banks. Not going into the legal aspects here when it comes to coil guns, EMP's and similar applications... I do have a few options at my disposal depending on how fast the charging needs to be but for serious applications with high power levels, fast charge rates and so on it soon becomes very technical. The differences between the US mains power and the rest of the modern world only complicates things here. So I was wondering who already build some decent cap charger based on inverter technology and if these people are willing to share their info and schematics for reference - if you already have an instructable explaining it a link to it would help heaps. Considering the costs of high performance caps circuits with proper protection against overvoltage and with good current limiting properties would be prefered over simple circuits that could damage the caps. Thanks for your help!

I'm doing some small scale brewing, and I want to rig up some custom labels & caps for a real professional presentation. Labels are easy enough, but caps are throwing a few spanners into the works... Does anyone have any ideas on how to print them? Here are my current ideas:Toner Transfer - use a custom template and rig to hold multiple caps, then use an iron modified into a solder-press-like device to transfer. removing the paper cleanly could be difficult, and the results are unpredictableSilk Screening - build a similar rig to hold caps in place, and screen them. i don't know much about creating screens, and longevity, but it's probably too complex/expensive for small batches.Custom Stamp - use a rubber or pre-inked stamp to impress the design. simple, but expensive for multiple designs. i don't know how well the ink for pre-inked stamps will bond to metal, and I don't know what ink to use for a rubber stamp.Any thoughts are welcome.

I am new to this so please excuse my stupidity. I want to make a capacitor charger (for a small coil gun) I know there are instructables about them but they are all with chargers that came from a camera which I really don't want to do because i would like to make my own circuit that i can play around with and not blow it up by accident. If someone has a link to a project like this please post if not i have another question. Could I just take let's say a camera that has an 80uF 330v cap and switch it with a parallel bank that has 5 or more 220uF 25v caps or something larger. Would that work or would that blow the circuit or would it be better to buy the same caps as the camera and hook them together. Thanks

I'm also making a nerf gun but I ran in a bit of trouble trying to attach a pump jack (is that what it's called? or maybe a tire valve ) http://img80.imageshack.us/img80/30/dscf0035ve1.jpgI need to attach a cap on the red circled end and in this cap there must be a mounted pump jack (the standard one like I would use with the pump below it), I tried to use a replacement tire one just make a hole and insert the jack with a round rubber end in the back but it would still leak and fall out. I went through at least 2 caps and 3-4 rubber tire valves trying to get it to glue/ceil it but nothing works. So i somehow need a metal/solid pump valve that would be attached to the cap solid and ceiled. Is there a way to attach one to a flat PVC surface so it wouldn't move without much force but enough force to put the pump onto it, anything without worrying of breaking it off and make sure its air tight (some product I can maybe?)Ok hope at least some of it makes sense, looking forward to any advice I've been stuck here for quite some time. Thanks a lot Alex

Hi, I’m experiencing problems with my LG Flatron Wide. The screen comes on with a very faded picture and then goes black. I assumed that maybe the capacitors (like for others) needed to be changed. However, I have opened the monitor and the caps look perfectly fine, no bulges or anything. Does anyone think I should just go ahead and try changing the caps anyway? Or could anything else be wrong? Thanks a lot.

Hi, I would like to create an almost parallel beam of light with an LED and a biconvex lens. Therefore I have to place the LED directly in the focal point. I thought of a setup with a PVC pipe with threading: I could glue the lens to one end and screw a cap onto the other. Then I would drill a hole in the middle of the cap and stick the LED through the hole. By screwing the cap back and forth on the PVC pipe I would be able to find the exact focal point and then fix the cap in place. There is just one problem: Lenses are either incredibly expensive or only available as sets. The only exception I found so far are lenses for google cardboard. They sell for just a few euros on ebay. Google cardboard lenses have a focal length of 45mm and different diameters, I would like to use a diameter of 25mm which is no problem. Now I wonder: Is the focal length of 45mm too small ? Will I be able to get an (almost) parallel beam of light out of this setup ? The LED is no ideal point light source. Originally I wanted to get f>80mm but that is really expensive. Anyone with experience on this kind of setup ? Tips you could share ? Can I get this to work, or will the approach be too unprecise.

Hello, I am looking for a supplier that sells metal tubing, steel, very small inner diameter with threading inside and end-caps that screw on to make it flush and appear as a solid metal rod (rubber O-ring if needed to keep dry). I am attempting to make paracord survival key fobs. I want to fit various tiny survival gear inside the tube, closed on both ends then weave the stitching around the rod. When needed the user can unravel the paracord for use with what's inside the tube. It must be tubing because one of my ideas is to put thermite inside a tube, wrap some magnesium ribbon around the outside, then stitch the fob around that. Other ideas include other types of survival gear but that one will be my fire starter fob. :) The rods would be about 2-3 inches in length, wall diameter thin but sturdy, inner diameter maybe 1/4 - 1/2 inches. Thanks for any help. Rounded end caps would work fine as well as they would give me more room to stuff things in, but I need access to the suppliers for both the threaded tubing and end caps. :)
