World Web shooter shop class

[Wadaltmon]

I have some really strong electromagnets I could wire up with a AAA and switch... That could hold it.
Have you begun to construct your model yet?

 

[White_widow]

I started the cuff today.

 

[White_widow]

I'm working on the cuff right now. Cartridges will be next.

 

[spidey44]

could you take the straps off of a watch and attach them to the cuff?

 

[White_widow]

I don't see why not.

 

[Wadaltmon]

An idea for the cartridges... Actually, not really an idea, but make them cylindrical. I am working on my canisters too, and they will waste material if you do not make them cylindrical due to expansion.

 

[White_widow]

That's a good point. I'll see what happens with rounded cartridges using the plastic stuff. For now though, I've pretty much finished the cuff. It's asymmetrical, but it holds the cartridge mold nicely. After I actually test the thing, I'll make modifications. After all, right now we want a working model.

So phase I is complete: Cuff

phase II is pending: Hardware

Phase III is pending: cosmetics.

Observations:

1.)Using a 4 oz cartridge will require more of the easy mold plastic.
2.)the material is much easier to work with when using a cast or shape.
3.)due to inconsistencies I need to build the cuff by layers.
4.) Because I can remold each part I make, I need to keep track of inconsistencies to reuse the plastic.

All in all, it's a good start. I'll be happier when I create a legitamate first cartridge.

When I'm not feeling lazy, I'll post pictures.

 

[Wadaltmon]

Cool! I want to see those pictures.
Also, by hardware, you mean like, electrical hardware? Or just all the "nuts and bolts"?

 

[White_widow]

Hardware encompasses the pressure tubing, solenoid valves, clamps, and cartridges. It's essentially what makes it work. I will post the pictures, but I'm going to remake the cuff. It isn't well made. I guess that's the problem with working with a new material. I didn't heat it equally either.

The second picture was my original idea if I decided to use a co2 tank in a backpack.

 

[Wadaltmon]

Not bad on the cuff, it looks like wax. I wouldn't want to use wax due to its low melting point, but, to each his own.
Where did you get that canister valve? That could solve some problems I'm having.
@Everyone looking at the topicoes anyone here have experience building electrical circuitry?

 

[SpideyScott]

Do you want an instructable?

Yes! Sorry I've been on the hype but forgot to check in! I'm not really a good scientist or anything, heck im flunking AP chem right

But I still want to see what I could come up with

 

[White_widow]

To wadaltmon: I could see that. While it does have a realtively low heating point, it has a tensile strength close to nylon. During the cosmetic step, I'm thinking of freezing it and covering it with silicon rubber. As for the valve, You can find it at party stores. It's used on helium tanks to make it easier to blow up balloons. You push on it and it desplaces a plug that will go right back into place.

To Spidey scott: What? but chemistry is so much fun Whatever the case, I now have three different ideas for a web shooter system.

2 of which involves solenoids, the other a push valve (like the white/black thing I have up there). Which one do you want?

 

[Wadaltmon]

I never knew that about wax. Also, I think it was a good idea to cover it in silicon.
@Spideyscott would you like my blueprint for the PVolt model?

 

[White_widow]

It's not wax. It's Polycaprolactone. Thanks. Also, I am going to remake my checklist (because it is way too much of a hassle ordering parts off of amazon.)

1.) make valve triggering mechanism (with strap),

2.) make hardware (cartridge, check valve, clamps, and pressure tubing.)

3.) Cosmetic (polymeric treatments to stop biodegradability and increase heat resistability.)

I'm remaking the cuff and I'm almost finished with a check valve.

 

[SpideyScott]

The original one you made, you said your formula only holds up to 20 pounds correct?

 

[White_widow]

i only made a device that fires fluid. I'm working on one right now. As for the formula, that is given you use alot and you let it dry.

 

[SpideyScott]

Yeah the device that fires the fluid, haha what I'm talking about.

 

[White_widow]

It was really simple. (a co2 bike tire inflator with pressure tubing, a clamp, and fluid in the tube.)

 

[Wadaltmon]

That seems easy. Also, here's how to control a solenoid valve with "Scratch" game maker: http://www.instructables.com/id/Control-a-Solenoid-Valve-with-Scratch/
Transfer this to a small chip and you're ready to go.

 

[SpideyScott]

i would have no idea on how to assemble that

 

[Wadaltmon]

Well, it tells you how.

 

[White_widow]

Alright guys, I don't know if I'll be able to come on for a while. I'm feeling very ill.

 

[Wadaltmon]

Okay, bro. Hope you feel better soon.

 

[White_widow]

Thanks buddy.

 

[White_widow]

Alright, I'm somewhat better. I got a really bad case of vertigo that comes and goes. Here's what's been going on.

I finished the web shooter. I'd post pictures but my custom battery died and I need a charger. I'll post when I can.

Pro's:
-The cartridge is hard as a rock. (it can't be drilled through) It's harder than the cans that hold real pressure.
-It's somewhat concealable. (it is half the size of the toy shooters)
- The cartridge holds like 4 oz of water.
- It actually looks like a spider.

Con's:
-The check valve is broken. (in retrospect, a soap bottle was not designed for pressure.)

-When attempting to fill up with co2 you create dry ice instead of filling up.

-the thing is hard to fill. I didn't make the entry big enough.

-It looks like it was made by a high schooler in a hurry.

So all in all, it isn't a functioning prototype. I'm going to remake the cartridge and replace the check valve with a schrader valve. I'll probably do that next week due to the constant vertigo. If I can charge my battery, I'll show you guys pictures.
