World Web shooter shop class - Part 1

[White_widow]

Man, my asperger's sense is tingling. Too many people on at once.

I can't say that I've read everything, but let me give my basic overview.

To Nolder: I saw your pm. I can do that. As for the glob. It's really simple to make a glob. It's all about not putting it through a spinneret. The adhesive isn't a problem if it's a strong pressure sensitive adhesive.

To Marvel Fan: I use a pulley system with a steel wire (picture frame wire) to pull it when I hold a ring. I love that Idea with the pvc. Nice!

To sammy: that design looks like it works. You just have to make sure that the seal is tight. Can you explain that principality situation? You want another forum?


I think that they didn't explain more about the web shooters as every second of editing that they need to do costs thousands of dollars.

Anyway, Friday or Saturday I'm going to the store to pick up a coupler and two tubes. That will compose the maximus 2.0

 

[nolder]

Hey WW I just saw your spinnerette video part 2 and I have a couple of questions. Why don't you just remove the rubber from your helium valve and just use the small tube inside? it's more sensitive right?

and maximus is designed to be like like the Noir model or Amazing model? the knot theory makes me think it's like Amazing.

and even with a spinnerette if the fluid hasn't cooled yet, it will still be a mostly liquid semi liquid right? so wont it be hard to grab a web line if its still liquid when its coming out of the shooter?

EDIT: and if the fluid is still hot, it could burn someones hands

The rubber is simple to keep a tight seal.

The noir until you add a spinneret.

No, the heat will remove the acetone, the material will harden, not liquify.

The heat escapes via acetone evaporation. It's possible that the CO2 would cool it down.

It's also possible for liquid CO2 to be a solvent. I learned how to make liquid CO2 and it might work instead of the acetone, thus removing the need for heat at all.

In fact, acetone was just for the test runs. The real goal is to fins a propellant that is also a solvent.

ahh I see. I wonder how a co2 solvent would interact with co2 from a co2 cartridge. they are the same right? liquid co2 except one is in a mixture.

Nolder: There's no need to apoligise. I don't feel at all that you were overcritical, in fact, I think that it's great when other people tell me what's good and bad about my ideas because it allows me to improve. Im sorry if My comment may have come across as being rude towards you, but I can assure you, that was not my intent.

 

[White_widow]

Actually, it's quite simple. Liquid Carbon dioxide is really dry ice under about 90 psi. If we were to use co2 to fill up the pressure vessels, then the co2's molecular structure would be less crystalline, and much more fluid. It's also done by raising the temperature in a contained vessel, but the story is the same. Pressure.

I just saw the movie, and I noticed something interesting. the fluid would remain a strand in the long term, but in the short, it was a bunch of tiny strands. That may sound simple but the thing is, it's more complex (if we are going by the movie's logic). The strands would wrap together, but only over time. That means that unless it's unraveling at close range, it's being spun/wrapped as it flies out.

the motor is delayed.

The spinneret is spun by a motor at high rpms. For it to do what I'm talking about, it can't have time to wrap, else the adhesive would bond it together. But this thing wraps a lot of strands REALLY quickly. So why is it that the ends are always showing (not a rope). That could be CGI, or in our case it could be that the spinneret doesn't start spinning immediately. It starts either after a quarter of a second, or it starts spinning after a specific command inputted by a switch.

Genius, or maybe seeing something out of nothing.

Either way, it would mean that to spin it into a "rope", the movie version used a motor. that doesn't seem to be too far off though. I mean look at the bottom right of leren's trial:

It formed a strand. The only thing that he did wrong was use a polymer that couldn't solidify in time. I can guarantee that his stuff created an unbreakable bond, but the result was too liquid because his polymer was basically a wood filler. That's why we would either need a heating system, or make sure that the propellant is the solvent. That's how we get the convenient state change. The viscosity is still an issue, but at least we now know how to modify and make.


Due to my desire to make a web shooter that is so simple a high schooler could make it, I'm going to avoid doing tests with electronics. However, for those of you who do want a device that can create short strands AS WELL AS the rope, you want to experiment with microcontrollers, solenoids, and motors.

 

[ng.samuel]

To white widow, about the new thread thing, I was just suggesting that we talk about what to once we have finished the device. I was not insisting that we open a thread, but I know that some people get annoyed when people start getting off topic. Since this thread is for the webshooter, maybe if we were to talk about the uses for the webshooter, we should open another thread. Anyways, it's just an idea.

 

[White_widow]

I don't really know... I guess we could ask iron spider to add a blog portion to the real webs for things like web shooter uses. I would ask him about it.

 

[MarvelFan1]

I already knew that its operated by a pulley. My question was how do you modify the aerosol button to shoot at the top. Because most of those small aerosol can on the side.

 

[ng.samuel]

No, that's unnecessary. I don't even think that I would even contribute to the thread very often even if it existed. I just wanted to know people's ideas

 

[White_widow]

Oh, that's even simpler. I drilled a hole on the top and blocked the side hole with putty.

and to Sam: alright.

 

[ng.samuel]

I do have a question, though. Theoretically, if the webbing was strong enough to support for swinging, how strong would one have to be to swing?

 

[Tyseg1cia]

in movie it used actual spider's web, and if u have enough of that plus it being spun around. that crap would be strrrrooonnngg.

and to Sam: alright.

I knew it. That was exactly how I thought you did it.

 

[spider 2099]

Hey guys I found something that can be usefull for the web shooter but it needs a power source I will upload an image soon

 

[White_widow]

I'm interested to see what you are talking about 2099.

 

[MarvelFan1]

I just watched the amazing spiderman, and I love it!! I was literally mesmorized by it, because I couldnt take my eyes off it! I had to go to the bathroom since the beginning of the movie and I didn't go til the credits! When he was doing these amazing things with the webshooter, by the time theend of the movie, i told my mom that was why I want to make the shooters, three times. Anyway, enough of my excited rambling! When he was sealing his bullet wound with webbing, that it is not just pellets, it's some kind of spray that hardens into the formed webbing. It kind reminds me of flex seal, how it sprays as a liquid and it immediately hardens into a flexible, rubber seal. but could this mean, if he were to use fluid instead of pellets, that liquid co2 could be used with the formula. As white widow said, it could act as a propelant and a solvent. What could get rid of the liquid co2, possibly a heated coil? Feel free to reply if I'm wrong!

 

[megajs]

i think the idea of the liquid co2 is that it removes itself when exposed out of its containment thus hardening the plastics. the idea is that we wouldnt need a heating coil

 

[MarvelFan1]

O okay I get it.

 

[spider 2099]

Guys how do you upload images from your iPod to this page???

 

[Wadaltmon]

You have to do it via a computer, I believe. Just copy the image files into paint, save them, and put them on an image hosting site. Or, copy and paste the picture from paint to here, I think.

 

[Iron_spider]

Just had an idea. For those of you using a tank, like me, this could be a pretty easy way to make a fluid meter or indicator. You could position an ultrasonic distance sensor at the top of the tank, on the inside. This would measure the distance between the top of the tank and the web fluid as it is depleted. That could be hooked up to some sort of LED display, and voila! You have a fluid meter.

Of course, an ultrasonic distance sensor is a rare find, and is probably utterly expensive... :\

White_Widow: The store that has cellulose acetate, only has actually cellulose acetate phthalate. I have no idea what that means (I've only taken 1 year of chemistry so far) ; is it safe to use here? Also, what were your results on the styrene experiments?

All: What is anyone using as propellant here; should I invest in CO2? How is everyone pumping it into their cartridges? I have chosen my cartridges, they are here: http://uploaddownloadperform.net/uploads/MikalCzech/binaca-peppermint.jpg
Easy to find, and don't expand much under pressure. I think this is my first choice. My second choice is a tank worn in a backpack, which I really don't feel like carrying around.

Also, my use for the shooter is to end chases, and perhaps tie up some things (nothing heavy like cars or anything), and to perhaps shoot at a wall and use as a handhold if needed. Swinging would really be a last resort for me, but just in case, I want to get the tensile strength up enough to be able to. My first web fluid (which WW uploaded to deviantart) would have enough tensile strength for this, if it didn't dry so fast and become rock hard.

Not really. Unless you consider thirty bucks expensive :P

Well, I stand corrected... do you have any Basic STAMP microcontrollers though? I am pretty sure they have to be interfaced with those.
