OH.., that's cool! Thanks for showing me that. Yeah, I have no isea what those other websites are, but that one works. That would most likely be a sensor. It's not really a fold up switch, or at least it doesn't look it. You have a contradicting idea however. You want that to hold alot of fluid. That couldn't hold an ounce of fluid, or maybe just an ounce. How are you intending to you use so much fluid with so little storage capacity?
 
Wow. Ok... that's pretty cool. It would be pretty cool to have something like that. This is my design. It's my final design, though I do have a schematic of everything underneath the shell. I'll save that for later though.

The cartridge can hold 4 oz of fluid. That is about 500 feet of silly string, but we are using more surfactant, so maybe more.
 
Wow! That actually looks like the real thing! Seems pretty legit, bro! Ace! The only things I see with it is A. I can't see it too well, it's pretty small, and B. On the back view of the arm, on the top of the part that holds the cartridge, what's that needle-looking thing? Haha.

Here are the components from my shooter:

Puncture needle:http://polyplayer.webs.com/photos/shooters/IMG_0689.jpg

The canister (after I spilled some of my trial web fluid on it, causing it to stick to my hand): http://polyplayer.webs.com/photos/shooters/IMG_0690.jpg
 
Points taken. There is a bigger version of the picture, it's just kind of messy. Second, the needle thing is the muscle of the arm. Based on where I think you are going with your shooter, I'm pretty sure you can fold the trigger as long as you don't use a metal bracelet. You're coming along pretty fast mr. Wadaltmon! My only question for you is, "how are you planning to pressurized the cartridge?" Other than that, great work! You've come almost as far as JMA610 and Leren. For now, you've got me beat.
 
Pretty much, I am using a small footpump (primitive, yes...) to pump up the cartridges. I also did a lot (2 huge tubs) worth of electrolysis (of water), and saved the oxygen and hydrogen in water bottles. I will use those as propellant, and feed it into the footpump, and then into the cartridge.
EDIT: Also, the cuff on mine is made of just a band of sheet metal, onto which I will solder or weld all the components.

Also, someone said in the fluid topic that helium would cause the fluid to expand.... what if a tube looped around in front of the nozzle, and caused the webs to expand depending on the setting? Just a little idea....
Also, I like the hidden solenoid idea! My only problem with that is the fact that the only solenoids I've seen or used were cubes, about 1 inch in all dimensions.... how is it going to be hidden?

Also, if you guys still do not know how to "cap off" the cartridges, just think... What has a lot of pressure inside of it constantly, and does not release it until punctured?

Not gonna lie. I'm super impressed. I've never considered pressurizing the cartridges with the byproducts of electrolysis. That was very clever. Primitive is never a bad thing. It means there are less parts that have a chance of failing. I don't really quite understand what you mean for the expansion tube. Is it similar to the way a water hose works? Just curious. Now as for the solenoid, the difference between my solenoid idea and the other's working on the project is that I'm not going to buy a solenoid valve. It's hand made from a coil of copper wire leading to a switch, a nylon t-joint, and a neodymium magnet, held by two equally sized springs.

Activate the coiled electromagnet. The pressure from one cartridge guarentees that the force on both sides of the t-joint are the same. Since the springs use the same amount of force, as well, it means that because the same force is on the magnet from both sides, it equals out and becomes 0 psi, the electromagnet can easily pull the neodymium magnet, unblocking the hole. When you deactivate the electromagnet, the spring will force it back in place, cutting off the liquid.

It can remain hidden because the small t-joint and smaller pressure tubing will be encased in the instamorph. This shooter is going to be bulky, but it falls into the, "hiding in plain sight" category. When under your clothes, this will make you forearms look buff. It won't make your wrist look monstrous. Because of that, I just need to be sure that the solenoid is unformly covered so that it doesn't look like I'm missing skin.

Also, the pressure capping system is not a problem. There is a check valve in the cartridge with a thin cap that can be easily punctured. With 100 or so psi pushing from the back and a sharp needle from the front, the cap won't hold. again, it uses springs (primitive as well) to hold the cap.

Sorry about that expansion tube bit,I misunderstood what you were saying earlier in the topic. My bad.
Also, my little idea was to use the valves that are used to fill up things like basketballs, footballs, and soccer balls... they contain a lot of pressure inside the ball, and do not release it until this "bladder valve" is punctured.
The only problem I have found with this is that without going and buying a ball and ripping it open just for the valve, you have to buy at least 1000 units themselves. Right now I think I will stick with a steel cap or ripping open the ball itself. Haha.
EDIT: If a neodymium magnet is what you want, then would I suggest looking at this article on http://en.wikipedia.org/wiki/Neodymium#Magnets ? It states in the picture that the magnet like this can be found on a hard drive.

Wow, Dubs. And new guy. This is the farthest and closest we've ever been. And to new guy, if you haven't already, check out page 12 to see the solenoid and experimental layouts that Dubs and I (well, mostly Dubs, but I kinda pointed out the idea) developed.
 
Waldaltmon I had the same idea with using a soccer ball valve. at soccer practice one of the balls got ran over by a car and i could see the valve sadly he wanted to keep the ball. you're making a lot of progress, keep up the good work. right now I'm using an aerosol valve.
 
I was really bored last night, so I read all the way through this forum...
Also, keep in mind I have been off and on working on this for 4 years, almost 5.

So am I, but I meant putting the ball on the canisters.
 
Believe me, I've already learned that the hard way.
 
With like four people creating a prototype, this should be wrapped up pretty soon. I only wished we could talk to leren about his/her model.
 
Leren? Who is that again?
EDIT: Can you reveal what is below the outer shell of your design? I am also interested on learning more about this "coupler" shown on your designs on page 12.
 
Leren is the first person to make a web shooter. It was bulky and really loud, but it functioned. It's web fluid was 1/3 cyanoacrylate, 1/3 elmer's, and 1/3 anti-adhesive. I think he also had some vinegar and salt. It fired about 10 feet.

The inner shell design is difficult to show because of the copper wires overlaying the solenoid. It detracts from the springs.
 
a coupler is a piece that connects the pressure tubing to the puncturing devices.
 
You can show a wiring diagram of the inside...
EDIT: Also, can you direct me to these posts of Leren?

Oh, cool! I like how this works! What is the power source though?
