Robot costume arms idea?

I am building the robot below for a Halloween costume. I am building the head, upper and lower body, arms, and shoes out of silver painted cardboard. But as for the arms and legs I need advice as to what to use. I know the material used in these pics has a name but I am clueless as to where to find them and what it called. The costume should be flexible enough to dance (AKA wave my arms in a worm-like motion) at a Halloween party. Any tips or ideas? Thanks in advance. If you want I'll make an instructable once I figure it out and build it if you ask. PS I am 5 feet 8 inches, and My arms are not too fat or too thin, and I am 14 years of age if you care.

Knife concealment??

OK, i was wondering about how to conceal a knife, and i remember listening to Nocturnal podcast by Scott Sigler, and one of the gangsters had a knife in his shoe. i was wondering if i could hide a knife in my shoe like this:1. put the knife under that removable pad in the shoe.2. cut a hole in the back of the shoe that looks like this:|..................... | |_ _ _ _ _ _ _| |......................|dont mind the periods, they are just place markers.3. tie a string (fishing line) to one of the holes in the back of the handle, run the line through the above hole in the back of the shoe. 4. drill a hole in a quarter and tie the string to the quarter, then stick it in your pocket. when you need the knife, grab the quarter from your pocket, lift your leg with the shoe and knife, then pull it out. the way you cut it, the flaps will open and the knife will slide out, but will stay closed all other times. could someone please make an instructable on this, or tell me if it would work by testing it out?

Boat made from 12,500 plastic bottles to sail across Pacific

The Plastiki is a boat that is held afloat by 12,500 plastic 2-liter bottles. Built by Adventure Ecology and captained by David de Rothschild, the boat will travel 7,500 miles from San Francisco to Sydney. Its mission is to create awareness about the vast amounts of plastic that get thrown into landfill or end up in the oceans. In addition to the wind power, the Plastiki will also be propelled by crew members bicycling along. Rain will be caught to provide water and sprouts will be grown in a vertical garden.

Open source tracking solar concentrator is go.

Meant to update on this here a while back. For nearly two years now I've been developing the prototype for a solar energy device makeable from scrap and recycled materials, using very basic tools and skills. It's now working, details available here: http://solarflower.blogspot.com/ Facebook group here. This has been possible largely due to the awesome help and support I received through this site. Currently I'm back in New Zealand, preparing the first free workshop on the device's construction and use, taking place the three weekends after Easter at the Tui community, Golden Bay. Then back to Europe for the summer and tour this thing around. Animated tutorials will be available at www.solarflower.org as soon as I find a spare second to do them and finish the website. My God I'm busy.

how to make electricity from temperture difference

Hi, One day I saw on Discovery a guy using a local stream to make electricity. really cool, he attached a light bulb to it and put that into layers of stone. by doing so, the stone heated and so he was able to cook on it. Basically what I am asking is, how can you make electricity from the local stream by means of temperature difference with the air temperature. TXS!!!

The Eco Powerplant

  Creating a Permanent IcePack in the Eastern Sierra A permanent Ice pack in a north south valley of the Carson Basin could insure constancy of water supply to Fallon area farmers and ranchers. Creating a permanent icepack in Northern Nevada is technologically and economically feasible, given the right location . This project will be solar powered, and serve as a peaking unit during times of high electrical demand. This technology will produce energy from solar by PV Panels mounted on a giant spanning grid over a north south valley in the eastern Sierra. A properly excavated mine could also serve as a location. Proximity to gas distribution and an electrical sub line are also important . This facilities' economic importance as a producer of LNG from surplus stock cannot be overstated. The upper part of the oval consists of a space grid spanning the valley or excavation. It is covered with steerable PV panels. The PV panels may be inserted into the grid or used to create liquid air , which in turn can be used to produce LNG. The thermal energy storage as liquid air would be contained underground in the mountainside itself.In Northern Nevada, these mountains are usually solid rock formations imbedded in sandy detritus, an excellent insulating material. Vast amounts of wind power are also available during spring and summer.   During summer peak demand, liquid air could be re expanded to run generators.   And most importantly , this plant will produce as a by product of its operation large amounts of water in the desert by freezing the ground on which it operates. Wet air passing over an expanse of frozen mountain rock will condense, and either form ice or rain. The production and maintenance of a liquid air production and re-expansion facility will also produce large amounts of water during times of high humidity.   Suitable locations in the Eastern Sierra would by necessity by close to either the Truckee or Carson River Basin.

architecture for grade 4-6, need lighting ideas

I volunteer on Saturdays in Watts/LA for a program with kids from grades 4-6. The program involves 6-8 week "classes" taught by volunteers, and I'm an assistant for a new class on architecture. We're building a structure, and I want to include both lighting and sound. For lighting, I sincerely apologize, I have no experience and not much time, can someone recommend a simple way to let the kids build some different LED effects, ideally AC powered, that they could incorporate into the scaffolding we built last week in first class (the structure will be about 6x6feet.) The second question, I think sound is essential to architecture, I happen to have some sanyo MP3 players, I was thinking of buying small MP3 speakers for each, and then letting kids experiment with what a wash of different sounds and music would sound like within the structure.Amazon MP3 speakers start at 20$. Any other options? I think it would be great to have strpped down speakers so that kids can build the speaker housing to incorporate into the architecture.  I can find + and - on a battery. Thats about the level of my competence.

Need muscle suit.

So here's the thing. I'm building a green goblin costume(humberto ramos kind) and I need to make my self look a little bigger.  I don't need to see any muscles just bigger. I've considered  using bubble wrap but I'm afraid I might die from Hyperthermia, plus if I sit down it would sound ridiculous. So the next obvious choice would be to use upholstery foam, but I've never worked with it before. I've thought about using plain old newspaper and and strap it down with duct tape, but I think that might be noisy when I walk. Check the pictures to see what I mean. One picture is from a comic book and the other one is a costume made by jacemoore on deviant art.

Help Needed: How would i make a 3-Section Floating Computer Desk (horizontal-diagonal-vertical)

I recently came upon the idea to build a floating or wall-mounted desk/workstation. I  am a graphic artist and use my computer area for computer research, drawing on my computer, drawing in sketchpads, printing/scanning, etc. its essentially my art-station.... So the idea came to give myself more room to get my work done, while at the same time not "crowding" my room, which isnt huge to begin with, since I don't have access to a separate office space. This idea could potentially give me enough space to draw and use my computer without having to constantly move things around to fit my materials. It would also allow for more leg room, as i could use my computer chair to roll through my entire area with no interference. I have a rough idea of how this might be able to work, but as i have never done any DIY projects, i figured i'd ask the more experienced people on here for their advice or opinions on the concept itself. and maybe if i am lucky i can get some recommendations on materials. i am VERY new to this and am running just on concept and basic logic; So the concept here is to have 3 pieces of wood, two of them will be 4' x 1' 6" ((48in x 18in)) and the center piece would be 4' 6" x 1' 7.5" ((54in x 19.5in)) however i would need to actually measure it out to make sure on that last one as i just did some quick math to scale of my drawings...  i have a diagonal wall in my room that connects to a horizontal and a vertical wall, which i plan to build the floating desk on. i included a diagram of how i plan to cut and connect the pieces (cutting off triangular pieces from each board should allow them to fit like a puzzle, to which i have to then find a way to attach them). Now, my question is, does this plan look doable. i feel it will be alot less expensive then buying a desk and i will have much more room for what i need. what would i need to support the desk? i would like to make this without legs if possible. while making it as sturdy as possible of course.... and i plan to add a sliding keyboard holder....i will not have many heavy things on top of the desk as shown on my diagrams, the heaviest thing would be an iMac which doesnt weigh much. i would also most likely stain the word a mahogany/reddish toned wood color. so i am looking for a sturdy would that can be stained fairly easily.... ((i will also cut a semi-circle hole on one of the boars for wires to go through, although i will have minimal wiring. I was thinking of using those L-shaped bracket things they sell at Home Depot to support the wood to the wall... they come at a maximum size of about 12 inches i believe....  Does anyone foresee any problems i might run into? any suggestions? is there some materials i should purchase. i have access to a power drill, and materials/machines to cut the diagonal/triangular cuts off of the wood. so yea, did i miss anything.. again sorry, this is my first DIY idea ever...!

A better version of Etsy without the resellers

Etsy has made it pretty clear that they don't plan on closing down the high volume resellers that list cheap imports as "handmade."  Helen Killer (April Winchell) of Regretsy wrote an excellent explanation of why this amounts to bait and switch on Etsy's account. http://www.regretsy.com/?s=bait+and+switch Most people go to the site thinking the majority of what they'll find is handmade.  Real makers, crafters, and artists post their items at a reasonable price considering how long it took to make the items.  Customers go to the site to find a specific item, search for it, and find a bunch of cheaper options listed with the handmade ones.  The cheaper items are often listed as handmade, and customers don't often do the extensive research to find out 1. how long a handmade version would actually take 2. the cheaper options were made in a factory overseas.  Considering that handmade was Etsy's big selling point, they have no reason to believe they're being duped by a reseller. Etsy also prohibits "calling out" in their forums, and often ignore the private reports of resellers.  Even if you have proof that the exact "handmade, unique" items in a seller's shop can be purchased for next to nothing elsewhere online (and in huge quantities), you're not allowed to mention it in Etsy's forums in order to warn others about what they're really buying. So far, shopdelighted.com is very small and new, but I like the clean interface and their promise to never allow reselling except in the case of crafting supplies.  I might be a naive idealist, but for now I believe that this site will actually keep their promise.

How many hours of direct sunlight comes from north of the east west line?

We all know that the sun rises in the east and sets in the west.  And it is true 2 days a year!   The other 363 days it is untrue.  I found a neat little website sollumis.com that  gives a  visual representation  of the sunlight at any day of the year and at any location and  in summer quite a lot comes from the northeast and northwest in the mornings and evenings. (where I live at about 49 degrees north). I thought the rays represented 20 minutes of sun travel originally but now I am not so sure because the hours of daylight in a day do not correspond with the number of degrees of sunlight.  Does anybody know how fast the sun goes down? Does it appear to speed up as it goes down in summer or does it appear at its fastest around noon?  If it goes down faster than it goes at noon then there will be less hours of sun north of the east west line but if it goes slower, there will be more hours of sun north of that line. I would like to know how many hours of light  come from north of the east west line so that I can  give a guesstimate about how much more light my lean away greenhouse collects compared to a lean to.  The various websites are good for giving the sun up and sundown times and angles but none I have found give the corresponding times for the sun passing  the east west line in morning and evening. It is a tricky question and I can make a physical model to figure it out but maybe someone already knows the answer. In the diagram the sunrise is 5.11 am and sunset is 9.17 pm and the sun rises at 52 degrees and goes down at 308 degrees.  The degrees divided by 360 do not tally with the hours divided by 24  0.67 for the hours and 0,71 for the degrees. Thanks for any help Brian

Notebook with removable pages? Similar to Circa / Rollabind

I'm putting together a DIY planner, but I keep thinking that I want to have the ability to add and remove pages at will. Some DIY examples I have seen that allow this are the classic hipster PDA, which uses a binder clip, and other designs which use opening rings. I'm not a massive fan of either - the binder clip is a bit too I really like the Rollabind ( www.rollabind.com/ ) and Circa (www.levenger.com/PAGETEMPLATES/NAVIGATION/Products.asp) systems. They provide a set of disks, and specially punched paper, that allows you to snap in and out pages at any time. A major shortcoming of this system is that their proprietary paper needs to be used - the system relies on the right shaped holes. The do sell a punch to allow you to use your own paper, but its very expensive. Are there any other systems out there? I might try the rollabind/circa system, and see how feasible it is to cut the paper yourself by hand.

Magic The gathering Mosaic!!

For those people that arent familar with magic cards they are collecter as well as playing cards that you can collect and what i intend to make a mosaic out of the art from these cards. the idea is a 29 by 47 tile mosaic (of a face) which will probably be rather big, the tiles will be approx 2 1/16 inches (5.24 cm) by 1 9/16 inches (3.97 cm)  so that will make the whole art work about 1.52m by 1.87m. so there will be the tiles all creating this picture and then i want to put a clear plastic sheet over the top (havent decided if i want it pivoted at the top of to have it completely stuck down but it is not really the problem). I would like to know of suitable methods for glueing each of the tiles as well as what to glue them too as well as bracing of the art to keep it straight and flat and all that, be it made of wood or anything nothing is a problem metal to some extent but yeah any ideas because what i have so far is the tiles ready to be cut and no way to stick them and no idea what to stick them too. any help would be appreciated and thank you in advance :)

DIY LED Growlights from LED Xmas bulb strings

I just got an Aerogarden for Xmas and it is a pretty neat little unit, but it has some annoying and expensive problems. The biggest one is that it uses CF bulbs that are on 16 hours a day, and they say that you need to replace the bulbs every 6 months, because the spectrum of the bulbs change as they age, making the plants grow less well. I did some research and found that the Weed industry has created a solution: LED arrays with a combination of red and blue LEDs (the color frequencies plants thrive on). These arrays are very long lived and use less than 1/2 the power of the CF bulbs in the Aerogarden. The problem is that even the cheap ones (200 LEDs) are $50, and you would need 2 for complete coverage in the Aerogarden. Then I had a brainstorm! LED Xmas Lights. They are already wired, ready to mount on a panel, and you can get Red and Blue strings of 100 on ebay for about $10 incl shipping. I don't know if they are the right Red and Blue, but it is an interesting experiment. Even if it does not work, you are set for Xmas lights for next year.

What can I do with lots of Magic: The Gathering cards?

Hi there. I have several thousand Magic the gathering cards, possibly over 10k at this point, that I don't really need. I was thinking about giving my room a nice blue tone by covering the walls with them, but I don't think I have quite enough blue cards for that. So at this point I'm kind of just wondering what I COULD do with them. A nice thing about them is that I have 30-40 of many of the same cards, so if I want a large patch of the same color for some reason, it's possible. For those that don't know, Magic cards are the size of a normal playing card, but about twice as thick and have detailed fantasy art on them. Primary colors used are blue, green, red, black, and white.

Not sure if this should be posted here, Outdoors or Square Pegs, but it's art related so I'll ask here. I once saw a how-to video, I am 90% sure is was on this site. but there is a chance it wasn't. I would like help finding it again. From what I remember, the person showing off had: a car battery, a long needle,  plank of wood and some chemical. the process I remember was (but may not be 100% accurate): 1. (s)he painted on a layer of chemical (or acids) on the wood 2. stabbed the needle on the wood 3. connected the battery to the needle 4. turned the battery on. it then made some elegant, fancy patterns, like a bare tree, or a lightning bolt. lots of 'branches' and paths were burned into the wood (without manual intervention. it was 'natral'). like a chemical reaction. if anyone has the name of this technique, or a video/instructable/guide, I would really appreciate a link. Thank! EDIT: solution found: it's called "Fractal Woodburning" (go on youtube for some videos). I should have known, I love fractials! you need: saline wood needles and a high-voltage power source. and patience.

The problem is that the paint doesn't run all the way to the edges of the wood and cuts short about 3 cm from the edge of the wood. The paint is also peeling towards the edges. The reverse side of the wood has a few crevices running along it(kind of looks like a turtle shell) as well as a few peg holes. My plan is to sand the front all over and try and smooth the edges of the paint where the paint is peeling. For the other side, I'm going to fill in the crevices and holes with wood putty and then sand over as well. Afterwords, I'll probably apply some dual paint/primer spray paint on top to give it a smooth finish. Now, I have a few questions: 1. Will the peeling edges be a problem when I paint over the wood? 2. Since the crevices are fairly shallow and smooth out pretty easily, will wood putty be a good choice for filling them? 3. Any problems with using a dual paint/primer? Or would it be better to use a separate primer and then paint? I've never really painted anything, and this is pretty much the first real craft project I'm working on, so any advice would be great. If you think it might be a better idea to remove the paint, any ideas you have on how to do it would be great too. I've attached some pictures from various angles. You can probably guess what I'm going to be making :). Thanks.

Plastic Tote Bin LIDS reuse ideas needed

I have 25 plastic tote bin lids that are headed to the land fill. Does anyone have any ideas for reuse instead of throwing them out?

Jawa's Junkyard at Florida Star Wars Celebration

Whoopee!! I am going to be going to Star Wars Celebration 2012 in Florida!! I will be helping out at the Jawa`s Junkyard We will be assembling and painting model Gonks with kids. So If you will be attending, swing on by our booth. Why is this in art?  Because I am so darned psyched that I drew some Jawas, and they turned out pretty decent, so I wanted to share. I included the black and white scan of the sketch and the coloured in more 'final' product. Cheers! EDIT: Added two more images to keep it "Art" related.

Guy Fawkes Airsoft Mask *help*

Today i asked my grandfather if he could mold my Guy fawkes mask for me so i could make a more durable version of it, i plan on using it as a mask for airsoft. He often makes molds of action figures and toys and fills the molds with pewter, however pewter is to heavy and i think to soft of a metal to use for airsoft, especially since the mold will be of a thin piece of plastic. any ideas on what i could fill the mold with or any suggestions?

volpin spine sculpt method+another one like it?/3d modeling help?

This is a 2 fold question: http://volpinprops.blogspot.com/2011...as-part-1.html http://www.youtube.com/watch?v=TNZK8-z0ndk&feature;=plcp http://www.youtube.com/watch?v=dTg5kpzXkJg&feature;=plcp http://www.youtube.com/watch?v=LsiGgR9HVJQ&feature;=fvsr http://www.youtube.com/watch?v=yDq_uHKZeIM I’m trying to use volpin’s method of make 3d objects using photos of views of an object, making a skeleton (he uses MDF; I want to use cardboard), and then placing foam or something sandable in the skeleton and shaping it using the spines. I also found this video where a guy uses a similar method and I was wondering if I could get some help on how I could combine these 2 methods. I want to use the method off the youtube video, but I don’t know how to do it with the side, top, bottom, back, and front view method volpin uses. Also, I tried volpin’s method on google skethup and just using the spines doesn’t quite give the results I thought it would. Does this mean you have to sand the rest of the way and make sure everything is even? If so, IMO, I would want to do the youtube method more (no offense volpin, im just not as good a sculpter and artist as you lol; I need lots of help). My second question(which ties in with the first) is about 3d modeling. I’m trying to make complex shapes using volpin’s method and the methods on 2 anim8or tutorials on the 2 youtube videos (the side views off photos) to make pepakura files, still using google sketchup. Is there a book or something I can use to learn how to make stuff like in the anim8or tutorials? Usually I could watch and teach myself, but for some reason my mind can’t wrap around the concept. Also, is sketchup bad for the job, and if so why? What should I be using (something free since this is a one time deal for me)? An additional note, I am currently using google skethcup and corelDRAW X5. Where can I learn how to make the reference photos like volpin makes (look for skyrim helmet on his blog and the daft punk helmet in the link) so I can send them to the 3d model program? What I’m trying to do is take pictures off of a playarts kai halo master chief and make armor files. Any help would really really be appreciated. Thanks in advance.

I need help!! Trying to draw a clockwork powered Golden Snitch!!

Ok, here's what I'm trying to accomplish. I want to draw a line drawing sketch of a Golden Snitch from Harry Potter with the clockwork mechanisms superimposed inside the sphere. The Snitch itself is easy enough to draw (a circle with a pair of delicate wings) but the clockwork mechanisms to power the thing are tough to do. The end result should, hopefully, look like an old "da Vinci-esque" drawing that was found in an old book. The aging of the paper is easy enough to figure out. So this is my question. Does anyone know where I can find a line drawing of a windup mechanism that I could easily draw in a scaled down version to fit within the walnut-sized Snitch body?

Question about solar panel circuit

I'm putting together a solar powered cell phone charger and I need some advice from someone who knows a thing or two about photovoltaics. I've spent the better part of my free time the past three days or so absorbing as much information about electrical charging over USB and solar cell output as possible. I've seen a lot of helpful DIYs, and they would be great if I was following their method exactly. Unfortunately my project has serious space and power constraints. It's not for trickle charging an additional battery, it's for providing direct power to a USB phone. Here are my specifications. I need 5V and preferably ~500mA. Anything over 400mA should work fine. I *think* I've come up with a way to get that within my space requirements but I'm not positive it will work because I'm mixing two different size solar cells in one circuit. I can't seem to find a definitive answer as to whether or not this is OK, and what the results will be. I've attached a diagram of my plan. Two 5.5V/70mA solar cells wired in parallel with seven 1.5V/50mA cells. If I'm assuming correctly, this will give me an output of 5.5V (before the regulator) and 490mA. I don't know how or if the lower voltages of the smaller cells will effect the output. Can I use a combination of high voltage and high amperage cells in one circuit to get the output I need? I've talked with people in the Science and Tech forums and I've gotten a long way on the electrical circuit aspects and USB issues, but I'm hoping someone here will know a thing or two more about solar cells to tell me if my plan is viable as it is or if I will have to modify it. Thanks for any help.
