waterproof material?

Can someone tell me what material I can buy that is lightweight, molds like clay, is waterproof and singeproof, and won't break the bank? does such a miracle substance even exist?

Patterned materials..

Trying to get  a jump on my costume this year for halloween and I want to a) plan ahead better, and b) base it on my character in Second Life. Problem is I have been looking at everything from shower curtains to upholstery materials, trying to find a solution, without much luck. Mainly due to the "best" match for what I want to try being an upholstery category material (and even that isn't.. quite right), but I have a lot of yardage involved, and it costs like $27 a yard or something... :p Basically, what I am looking for is something rubber like, so flexible, not overly "glossy", with enough thickness it can be layered, but with fairly fine detailed patterning on it. The original "suit" this is supposed to mimic looks a bit like layers of flexible armor, layered over each other, but both due to the design not being mine, and the prospect of, once done, photoing the result, doing a bit of Photoshopping on it, and "replacing" the in-world version I currently have, I want to make it slightly different. The problem, of course is that I am running into a problem of finding any material, never mind what fits the bill, save for, maybe, buying just smooth, rubber sheeting, similar to inner-tube material, then trying to do something with it. But, how, if I had PVC rubber, do I add texture to the thing (other than, for example, trying to airbursh a pattern over it, which I have zero skill at)? Nearly everything is the wrong material, too big a texture, or just.. not one that will work. Mind, best possible texture would be something like: http://i19.photobucket.com/albums/b194/Dakra/Tech256.jpg But, that ain't happening, so.. something like: http://image.shutterstock.com/display_pic_with_logo/75178/75178,1310971434,2/stock-photo-hi-tech-background-blue-metal-texture-81298300.jpg or even a very small pattern or honeycomb, like: http://images.colourbox.com/thumb_COLOURBOX2412500.jpg Would work. Heck even if I had to decal the stuff on, somehow.. But I am at a loss here as to what material to use (mainly do to finding a place to get it cheap, and not in some insane amount), and if I can get it, how to make the result not look something like the attached image, or better, add the texture to it I would like to see. Any ideas at all?

Material Section

Hi there!I hope this is the right section to post this in, if not then i'm sorry i picked the most probable one (i hope D: ).First of all i love instructables, i'm using way too much time in on this page than i should, but then again if it wasn't or instructables i wouldn't have this cool new Hard Drive Speaker present for this cute girl i like ;)In any case let me get to the point; i would like to suggest a Materials Section for Instructables - basically it would include material stats and an in depth explanation of the material (or component if we're talking tech here, but that's a different area). Here's an example: in an instructable, the author mentions plexiglass and that it needs to be bent. Many don't know that plexiglass isn't class, but an acrylic hardened plastic substance with abilities much like glass (but not quite). Plexiglass can fracture, but wont leave extremely sharp pieces like glass will and it can be bent when under medium-high heat from a heatgun or the like. Also that high friction (from a drill or the like) will cause it to melt.Basically what i mean here is that this section would greatly reduce the time an author spends on making his ible by letting out basic facts. E.g. instead of writing "plexiglass is..blah blah" the user would be able to look up in the materials section and read in depth for him/herself what the characteristics are for plexiglass/plywood/capacitors/batteries and so on.The materials page could be powered by the "burning questions" competition i've seen on this page. I don't think material characteristics fit in ibles because it strictly isn't - it's a data sheet that lets you understand the materials and components you're going to use in an ible.PS: sorry about the lower case i's and the occasional typo or grammatical error i'm not a native english speaker . also i really hope this is the right section to post in...

Materials question? Answered

I know it is possible to by "flexible plywood" or "flexible MDF" - sheet material that can be rolled up in a single direction, whilst remaining rigid in the other. However, I have only found versions that roll with a minimum radius of about 15cm / 6". Does anybody know of a similar material that can be rolled with a much smaller minimum radius, say only 5cm / 2"? It doesn't have to be wood, any easily-worked sheet material will do if it can be rolled in one direction whilst remaining rigid in the other will do.

Tube Material

I started thinking about how the tube material could be improved. Although I love the ghetto look of pringles wrapped in the invincible duct tape, improvements can be made. You could use PVC or ABS for the tube, it wouldnt need pressure rating because Im sure this thing wouldnt have enough power to explode the pringles/tape team. This is rather cheap and you could just glue on an endcap. Then a BBQ ignitor can be threaded in, a ring to define the chamber and barrel and fuel sprayed in! However getting the perfect cost/durability/strength ratio is hard.

Toys/ Materials

Originally Mod Squad was born out of the idea to use donated toys to create prosthetic arms because there is an over abundance of them in the US, they are fairly low cost, they provide a variety of materials, and children would enjoy the way they look as opposed to more industrial materials. However a big concern is their durability. Share your thoughts/findings/suggestions about using toys. Are there other existing materials that are easy to access and would be good to re-use but would also make something that a child would like?

Semi-Solid Material? Answered

I was hoping anyone knew of or had a good suggestion for a material that fits my description. Either a rubber- like material that was softer (more malleable) than rubber, but tougher to prevent tearing or a putty-like material that would change to a firm solid when heat or a current was applied. I need something that can be molded to a specific shape and then hardened to hold that shape, but can later be returned to the non-molded shape.

Semi-adhesive materials

Hi, I'm looking for some suggestions of what I'll call (out of ignorance) "semi-adhesive materials". I am looking for a large sheet that can be folded, or preferably tightly rolled (think a window blind) and a variety of shapes that can be stuck on and repositioned. I've had a look at display felt for use with hook and loop stickers. The felt is quite thick and expensive. I'm just wondering if anyone else has experimented with this kind of project. Flexible magnetic material, or some kind of static attraction or something? Cheaper the better really, but durability is a big concern too. Any pointers in directions to look would be greatly appreciated.

Flexible arm material

I'm looking to make a flexible arm that I can position however I want. I need it to have a fair bit of holding strength in that I don't want it to sag. It doesn't need to hold my body weight or anything like that and it can vibrate or move a little without being a problem. Immediately, two things come to mind: the plastic pieces used for coolant in machine shops that has now become a common material for something like this. The other is made up of stacked plates with a ball on one side and a socket in the other, I wire or something of the sort is put through it and a tensioning knob is used to pull it tight and keep it in place. Commonly, I see these in mag base indicators. I'd prefer to find the second one. Though, I can't seem to figure out what to look for in order to make my own. The best thing would be to find a modular kit that would allow you to make one fo any length (I need one that is about twice as long as a mag base indicator mount). Any thoughts on what or look for or anyone know where you could find something like this? P.s. this is going to be used as a way to hold a small screen. If it works well, I may adapt it to work for other things.

Braided Wool Rug materials

I have the "ingredients" to make a great braided recycled wool rug: for years I saved wool fabric, bought wool slacks and skirts at Goodwill, etc, then cut them into strips, sewed them together, and pressed them into beautiful balls of wool, all ready to braid into a medium-sized (I think) rug. I didn't feel like doing the braiding part, so I tried finger crochet with the wool. That also works, but it will make a smaller rug (think several door mats). Still no motivation to finish this great recycled project. So, all this prepared fabric could be yours! You could also knit thick, cozy wool slippers. No instructions included for any of these projects; feel free to write your own instructable. Colors include navy blues, lighter blues and grays with a little red thrown in here and there. 11 balls total. Name your price, and pay actual ground shipping.

P.S. i know that osmium when oxidized has a smell and is toxic (and will cause the skin to turn black) i also know that platinum is a "traditional" wedding ring material and therefore can be made into a ring but the others i am unsure about.

resin or other material for sink?

I'd like to try making my own bathroom sink, and I'm wondering what sort of material(s) would resist cracking / chipping / discoloration, and preferably not be poisonous.   My first thought was some sort of cast resin.  Googling "cast resin sinks" will turn up a ton of cool looking products.  Bonus is being able to light it up from the inside.  I'm not sure what sort of resin is used for those products, though. I also considered the "inverse":  sculpting a shape out of wood etc., then layering it with something like Aquaresin with fiberglass reinforcement, and polishing.  Might not be a tough enough surface, but perhaps could be sealed with an epoxy / urethane / what have you. I'm not sure that going fired clay will give me the modern / futuristic look I'm going for... Unless there's a way to have someone apply a glossy ceramic coating to a piece that you bring in. Concrete was considered and discarded - mostly for aesthetic reasons, but also weight.  Really, resin seems the easiest route - but still looking for input from any materials experts out there.

Adhesive/fill material needed

I need an adhesive or fill material with some special properties. It should be a moderately viscous liquid that sets up into something very flexible, jellylike would be ideal. It should be applicable in very small quantities. It should flow before curing and be self leveling unlike silicone adhesive. Tensile strength is relatively unimportant. It should not adhere to two part tin based casting silicone. An analogy that comes to mind is E6000 adhesive but it's viscosity is a bit too low and it sets up way too hard. UV cured resin like Loon UV Knot Sense (great stuff that I learned about here) comes close and has the right viscosity also but also cures too hard. If you know of anything, I've got a project on hold until I find something and would greatly appreciate advice.

Built of recycled materials, but is it "green"?

Construction is nearing completion in Taipei of a plastic bottle building. Technically a temporary structure, "the world's lightest, movable, breathable environmental miracle" (say the designers) is also strong enough to withstand typhoons and earthquakes.  The building will eventually become an exhibition space. Much is being made of the structure's "green" credentials - LED lighting, and particularly the construction material; 1,500,000 recycled PET bottles. That sounds great, and in most of the news coverage of the structure (such as the BBC and Treehugger) it sounds like the building is built directly of bottles that have been re-shaped somehow (maybe squashed in a heated mould).  The bottles even have lids, and they talk about filling them with air, water or sand to change the thermal properties of the building.. It turns out, though, that the building material is not "PET bottles", but "PET bottles chopped up, melted and re-formed into much thicker-walled bottles intended solely for building", branded as Polli-Bricks. OK, still recycled, still greener than most building materials, but it smacks of spin to just say the building is built of bottles. The Polli-Bricks are impressive - individually nice to look at, and fitting together snugly "like Lego" - but there is no indication of how much energy is spent creating them.  They are made by Hymini, but the Hymini website flashes up all sorts of alarms with my firewall and anti-virus as an "attack site".  There is more information at Miniwiz as well, but some of the links there also trigger alarms. Maybe I'm being a wet blanket. It is a nice building, after all. What do you think? GreenMuze article

Adding Other Materials to the Mix

Over the past couple of years, I've evolved from being totally captivated by my 3D printer, making everything I could think of out of the three plastics I can print with, ABS, PLA and Nylon, to having the Replicator, sitting in my shop and becoming "another tool".  A tool that stands in as an "employee", who can make things while I do other things. Along with doing a pretty good job of making my designs, I've experimented with stepping in, during the print, adding components made of other materials, such as cloth, metal and other plastics.  I've successfully made pulls on tie bags, an electric push button, aluminum mounts for my project car and spring clips to hang my wife's potato chip and popcorn bags in the kitchen. Has anyone else been able to use their printer to make items, not 100% plastic?

Effectiveness of sugar as a piezoelectric material

Most of the sites discussing piezoelectricity mention that sugar crystals can be used, but I have not found any examples of them being used. I've just tried it with about a 1cm chunk of low quality (conglomerate of small ~3mm crystals) crystal, and got a good 100mV wave when tapped with a pencil. I've not tried applying a signal to it yet, and some better single crystals are growing at the moment, so I was wondering how well it works compared to commercial piezoelectric compounds. I've not done anything like this before, so if anyone knows where I can find information of the best way to mount and apply a signal to the crystal, it would be appreciated. Thanks in advance.
