Pop bottle caps?

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.

Bottle Cap Beads

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!!

Hi-Cap horizontal magazine concept

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

Samsung lcd bad cap problems

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?

What cap. do I need? Answered

I was looking at this instructable ignition coil and I built it without a capacitor, it worked fine except the coil gets hot after even very short run-times.  So he confirmed that I needed a capacitor to stop the overheating. So I added one.  I used the kind he told us to use (film) and I tried multiple ones, but none worked.  He told us not use the metal can type so I didn't at first, but later I got a really big one and tried it.  It was the only one I got to work, but then it exploded, so now I don't know what to do.  He hasn't gotten back to me, although it hasn't been very long so I don't accuse him, I would just like to know.  The capacitors are storing a charge, its just not running the coil for some reason.

Beer cap coffee table need hinges

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.

What would be the best way to to drill/press/punch a perfect 3/4" inch hole into a big bottle cap?

I would like to put a 3/4" inch hole into a big bottle cap so I can connect a water valve through the cap.  What makes this interesting is that the Cap is very thin metal, and because a valve with a rubber washer is attaching to the cap it needs to be a perfect circle so water wont leak out.  Plus, I would like to be able to mass produce this item (100 an hr), so the method needs to be quick, clean and reliable.

BB firing flintlock mockup

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
