Best of both worlds (LED technology)

People working under Professor John Rogers of the University of Illinois at Urbana-Champaign have managed to combine the robustness of inorganic LEDs (the kind we use so much here), with the physical flexibility of organic LEDs.They have devised a new mass-production method that allows large numbers of small LEDs to be picked up by a robotic arm and embedded into a wide variety of other surfaces, including glass and rubber.The LEDs are bright enough that they can be spread out far enough to be transparent, paving the way for displays built into windows.This is not new science, just new engineering. What would you do with it?BBC storyUniversity of IllinoisThe BBC picked the story up from Science magazine.

Flexible LEDs to boost biomedicine

Nature News is reporting today on the development of thin flexible sheets of LEDs which could be used for medical diagnostics, or even implanted in the body to use with light-activated drug delivery.  Besides these uses (obviously cooked up for the grant proposal :-) ), the clothing and other DIY uses seem fantastic! The interesting thing to me is that these sheets are made with conventional semiconductor LEDs (surface mount) and the flexibility of the leads is handled simply with extra lead lengths to pick up the slack. The original paper is being published in Nature Materials (Kim, R.-H. et al. Nature Mater. doi:10.1038/NMAT2879 (2010).

Looking for Heat Resistant Flexible Material

I am trying to find a heat resistant material that is flexible... I am trying to make a pull down shade to attach to a tension rod, that will make my home more energy efficient... This means It will also need to be thin enough to roll up into a small roll... It needs to be reflective or at least block out all the sun... I work nights and sleep through the day, and have trouble sleeping when the sun gets through...

Flexible PCB rewiring

Hi,     I'm working on a project where I want to strip a 'roll up piano' down and take the rubber keyboard innards which feed into the electronic sound unit and get rid of the floppy rubber roll up piano keyboard and replace it with a standard PC qwerty keyboad. I got used to using a qwerty keyboard for playing tunes already and want tomake one that is stand alone that I don't need to connect to the PC to play music with. That means I need to take all the connections that you can see in the photos I uploaded and re connected each one to a key on the keyboard.  First of all, I don't know if pressing the rubber key on the roll up keyboad 'completes a circuit' and therefore prompts the electronic unit at the end of it to play the sound or if it 'breaks the circuit'. These units have two flexible pcb sheets as you an see in the second photo so when the rubber key is pressed they touch (although they all seem to be pretty much touching anyway). In an old casio solid keyboard I have there is a hard pcb and the piano keys touch a small rubber disk (much like is what under qwerty keys) to the pcb.   would it be better for me to take a razor and painstakingly slice up the flexible plastic which the pcb is printed on then lead them to the innards of the qwerty keyboard I'm going to modify or would it be better for me to just chop the flexible pcb off and use some kind of very thin coppe wire to feed dirctly into the unit and to the underside of the qwerty keys?   Any guidence would be appreciated.

WANTED: 3mm flexible plastic fiberoptic filament

Dear friends: I am looking for 3mm flexible transparent fiberoptic filament. I recently got one of those 'LED shoelace' kits off eBay and I have use for the fiberoptic filament itself, not the LEDs and driver circuits. The filament is very flexible, somewhat rubbery in texture. I believe it's polyester or silicone. It's not a wonderful light conductor but it will work for my purposes. I have attached an image. The filament is the exact diameter of a T1 LED. Any help in finding this stuff would be most appreciated. Thanks!

Light(ish) and non flexible.

I am toying with the idea of putting together a non flexible notebook case. I really liked the look of my Timbuk2 sleeve and other sleeves out there, but they always leave out adequate support to prevent flex when in a messenger bag. I am pretty sure that being flexed across my back while cycling with a good amount of weight pressing on it killed the motherboard (twice!) on my old notebook and would like to avoid it again. I need some materials suggestions though. I need a non-flexible material to act as plates to be sewn into the outside covering of the case. Ceramic plate would be ideal, but the things that I have found are anti-ballistic and ridiculously expensive. Plate steel would work but it is heavy. Anyone out there with experience with plate steel or aluminum that can tell me how thin I can go without flex, or maybe some advice on materials that I haven't thought of?

more flexibility with authoring Instructables

Hello, Is there a way to put images in the middle of text in a instructable step?  I seem to only be able to put the images at the top.  That's not very useful. There's no way to drag and drop an image where you want it. There also doesn't seem to be any html tag option - it seems Instructable go rid of that button, although I see Instructables from people that tell are using that button.  What's going on? Thanks, Eric

Flexible Urethane Foams

So I was looking for a way to make a new seat cushion for my car (driver's seat is starting to decompose). I was looking for a memory foam or some other flexible pour-able foam.I came across this: also contacted smooth-on for advice on what density foam I would need for a seat cushion and bolster (from inspection - the factory seat cushion was made from a pour-able foam cast in a mold).In any case -- just passing this info along. Not sure if anyone will need or use this - but I keep a list of suppliers just in case someone I know is looking to do something ;) If anyone else knows of another supplier -- let me know. I probably won't go this route ($100+ for 1 seat cushion is a bit steep) but it may be an option :P

Can anyone please help? I am looking for a way to display several softballs for my daughter. I was hoping to find a way to mount a length of flexible clear plastic tubic, approximately 10" dia. on an arc and have an opening in the top to insert the balls and have them then roll to either side. The balls have stats written on them, so I would want to be able to manipulate them afterwords so the writing would be visible. My first problem is find 10" dia. flexible clear plastic tubing. Any suggestions would be greatly appreciated. Thank you

How can I glue thin, flexible, plastic to wood?

I'm trying to waterproof the inside of a box by gluing plastic to the sides. The plastic is already in the right shape (I melted the edges together). The problem is that the epoxy sticks to the wood but not the plastic. It just peels right off. Any suggestions? It doesn't even have to be glue. You'll probably hate to hear this, but lots of stuff isn't available here, hence hackish solutions are probably the best. Thanks for any help. Just so you can get the idea a bit better I'm attaching a picture.

Someone to paint a white, strong & flexible ring from Shapeways

Hi, I would like to buy a ring from Shapeways but before buying it in silver I would like to buy it in plastic to see if I actually like it on my finger so I was wondering if someone would be able to paint it for me. The main colour would be silver with a little bit of green and blue on the face.  As for the paint I was thinking of enamel or acrylic depending on which would last longer. Would anyone be interested in doing this? Side note: Would I get a better response by having this thread in the Art section of this forum?

Paper Batteries

Has anyone read anything about the up and coming Paper (thin) batteries ? Paper Batteries: A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper.A paper battery acts as both a high-energy battery and supercapacitor, combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies.What do you think? Will it replace these monsters one day?

Flexible bedside table?

As I mentioned in another post, I'm working on a nightstand/shelf with a built in dock for my iPod. Besides getting that to work, another challenge I'm facing is finding a way to cram that shelf into this spot at the head of my bed. At the end there is what, in denmark at least, is known as a "french balcony", which is basically a door leading nowhere. The trick here is that I would like a shelf spanning the entire width of the door, to place books, my phone, speakers, cups of water etc. but I still need to be able to open that door slightly to cool things down in the summer. I have a few ideas for how this could be done, but I would really like to hear if anybody here has any suggestions on clever ways to go about this.

alternatives to fiberglass

Hey guys im building an enclosed recumbent motorcycle and i am a bit stuck. im making the outer skin. to get a working aerodynamic shape, complex curves and all i want to use some flexible sheet which i can connect to the strong points of the motorcycle. i am thinking of using that polypropilene chicken wire, and i wonder if it would be good enough to be the base of the fairing and put fibreglass on top. my brother wants to use cedar strips as a base and cardboard strips mounted over them and fibreglass the resultant mess. then bondo the lot. any ideas. i am not describing this very well. a single sheet of a flexible matting will save me the trouble of making a mould of the fairing. thanks guys.

Suitable Martial Art?

Hi. I've been considering taking up a martial art of some form or other. Only problem is that I really have no idea what it is I'm actually looking for. I've read lots of articles which all pretty much say the same thing: "What do you want to get out of it?" so, I made a list. I'm seventeen, I'm not particularly fit, flexible, agile or disciplined and the things I want to get out of it are (in order of highest to lowest priority): • to become faster, fitter, more agile and more flexible • to be able to think more clearly • to step out of my comfort zone and be more active • to be able to defend myself if attacked • a suitable form of unarmed combat to augment my weapons skills (I try to practice western sword fighting from time to time, I'm not too good though) • to improve my weapons skills Any ideas would be really helpful, but I would like a logical reason to consider it. Thanks.

I am just curious if its possible to make any flexible OLED at home whether it be just giving off light or a tv screen. Please if anyone knows the full process make a step by step don't just explain the theory like in the wiki or here Here is an example of what im looking for;=related In the very least this could be cool for making clothes,costumes,indoor lighting,etc. In the best case scenario this would be used for a home made pip boy,laptop,cellphone,tv  I have been seeing allot of fully functional concept models but no solid release dates for retail. Despite the fact its allot cheaper to make tvs with this, im sure it would be twice as expensive to buy.

I'm trying to make a Breast Plate

Hey, I'm going to build a piece of FANTASY chest armor. I'm not going for realism or authenticity. Just making "a pile of spikes" that looks cool in my opinion. I'm thinking of making something to the equivalent of a low neck line tank top out of leather / tight weave canvas, and then covering it in steel plates. I'm thinking of dividing the front suit into groups and bands of plate. So I'm going to have a set of bands from the right and left chest, then another section that joins them down the center. A section for the abdomen, a section for each side, and then similar sections for the back. I'm then going to bolt the shoulders onto their respective chest plates. So I've done a crappy sketch on GIMP, Kinda explaining what I'm going to do for the center line of the chest. I think If I do this right It'll allow a lot of flexibility, might even be able to see my chest expand and contract while breathing which I think would be a cool effect. Is there any reason why this wont work? But are there any key factors that I need to take into account when doing this? Parts that need to be more flexible than others?

Seeing as knex is light, strong and flexible, and most importantly, using rods, I beleive it would be feesable to build a Knex 'glider'. After seeing how gliders are made, it could be possible to build a lightweight spacframe wing out of knex, and make it fly using clingfilm as its 'skin'. An extra boost of gliding power would come from a clingfilm propeller, powered by the very fast and smal, solar motor. Do you think it is possible to make something like this glide 10 metres?
