Capri Sun Jacket

This packaging reuse takes 140 Capri Sun juice bags and turns them into a full-on jacket. It's an impressive bit of reuse. I can't imagine drinking that much Capri Sun myself, but if that's your thing then why not flaunt it to the rest of the world? Capri Sun Jacket

Firefly Lights Jar

So while browsing Instructables, most times I see quite a few Instructables for the sun jars.  While on Think Geek today, I saw the Firefly Dreamlights Jar.  I was just wondering if someone wanted to take a crack at making it so that I can make one myself (im not that great with figuring out circuits on my own). Thanks!

making a very powerful sun beam

Hi there,  I  have a question and perhaps you could be of help to me, So my question is ,  is it possible to use cheap Mylar blankets(parabolic form) to concentrate the sun light, so as it would be able to cut through metal. My idea is to use 3 Mylar sheets each  1m square  which will reflect the light towards another  one which will work as a collector and then further concentrate the light to about half a millimeter.  Doing the math (0.5mm²/3m²) is more than 16 million (ok there  will be a lot of loss , lets say 50 percent). The question is, is this worth trying cause i don't want to waste time and money on this. So if someone knows why this wont work , it would be very helpful. thanks in advance

I need help for my kids room

I am trying to figure this out and I am not very artistically inclined. I want to make an 8" globe look similar to the light bulb I have posted  a picture of. I am making a solar system that hangs from my sons bedroom because I am remodeling his room in a space theme. I will also be doing a fiber optic star ceiling above it, so it will have day/night modes if you will. I want the sun to be a hanging globe light that looks cool, and I remembered those spikey light bulbs they used to sell in the head shops when I was younger (much younger!). I have gathered that it is done with silicone, but I can't figure out the technique. And how do you get it colored? Any help would be appeciated and I would love to see if somebody could figure this out. Thanks!

Finally finished my solar collector prototype.

This has been an ongoing saga for the last six months or so, but with a lot of help from many of you here the Sunflower prototype is finished. And it works! It still needs perfecting, but the principle is sound.This unit cost me less than $20, is almost entirely recycled and salvaged materials, was ridiculously easy to make (tho since I've thought of a way to make it much simpler) and seems to work fairly well. With a larger collector and light pipe in place this unit alone could collect up to a kilowatt of power, maybe more. Now I need to start working on the Mk II perfected design, and some applications for electricity generation and water purification.This will be an ongoing open source project. Once I've got a design which is nice I'll get a website up and be traveling round working with local community groups, inventors and NGOs.If you have any desire whatsoever to take a crack at making this yourself please please do so. The video is a little light on the finer details, so if there are any questions just ask.And thanks again for all those who helped out.

Solar-powered laser (supposedly)

 I was in this other forum about the Mythbusters' "Archimedes' Death Ray" thing. Our discussion went off topic, so I made another topic! According to Google, a laser is a device that produces monochromatic, coherent beam of light. We have established the coherent part of it by focusing the Sun's energy on point which has a mirror so theoretically, that focused part of the beam should reflect off the mirror. Our design(s) is/are based on multiple parabolas (or Fresnel lenses) to collect and focus light. The light is in turn reflected off mirrors to be combined on a mirror (or lens) which will be used to aim the light to the target. Unfortunately, I forgot the "monochromatic" part of the laser, but that's not a problem. All we have to do is put filters on our parabolas. That should be a cool enough part to filter the light without melting the filter(s) itself / themselves. What would be an idiotic thing to do is put the filter right in front of the last mirror, because it would melt it (unless off course, that filter was a pane of glass).   Any suggestions/comments/design ideas please put them up here. If your idea is just downright stupid (sorry, I don't know what else to use (other than idiotic, or crazy, actually crazy's better than stupid (back to topic))). If it is stupid, I will not use offensive words against you (unless you were swearing on my face); you will, instead, be facing the following words: "Sorry, your (insert suggestion/comment/idea) is not feasible. Please try again". I know it's a bit funny; part of it is for your entertainment, part of it is for your knowing. Again, please post any suggestion, comment, or ideas. By the way, if it's only a bit stupid, you won't be needing to face the words... Have a nice day!

Ideas for a sun for my model solar system?

I've just built a big model solar system for use in class, and i'm trying to think of what to use for the sun. The planets are roughly the right sort of varying sizes, and Jupiter is ten inches in diameter, which means the sun needs to be pretty big. I'm thinking of a big hemisphere to cover up the base, like half a big plastic ball, but I'm not sure what to use as the size lets out most plastic balls that i've seen. All suggestions welcome!

Insulating Ducts

We recently had a couple of trees cut down in the backyard and now our HVAC unit is completely exposed to the sun for most of the day! We bought a shade to set up but I was thinking the styrofoam would just be a little bit more of a help! What do you think? All ideas and advice would be greatly appreciated!

Don't try this at home, EVER ! The trip to NYC

Ah, I have finally gotten a little time to put some of the details up about my Trip (definition of trip, to stumble, fall, or to almost fall....) to NYC. The bus ride to Manhattan was uneventful. We were dropped off behind the Winter Garden Theater at 50th St. and 7th Ave. For those familiar with the city, this is a little north of Rockefeller Center, and a little west of Radio Music Hall. My little adventure started with me being a little greedy with what I wanted to see on this short day trip. I started down 7th Ave. and decided to scoot over to Broadway. In walking down Broad way (heading south, now) one have to be careful as it crosses the other blocks on a diagonal and it is very easy to lose the road and end up on 7th (and further south; you start ending up on 6th Ave - the Ave. of the Americas). The blocks heading south were shorter then those in the East - West directions. Walking through the Theatre District, and finally reaching Times Square (which is on 7th Ave), I was taking my fair share of pictures (Later, after I get them all posted, I will have to get my Sis in Law to help me identify the buildings, etc.) . Moving from Times square, I get the Garment District. This was a fairly quick walk for me, I didn't see much I really was impressed by there. Madison Square Park, was a nice little area, and then came the weirdest building I have EVER seen (and I have seen a house the shape of a shoe), I came upon the Flatiron building (see pics). In the Flatiron District was Union Square park. A fairly small park. Now, the streets going East and West were numbered, and I had started at 50th St. I was now at 12th, where Broadway becomes University Pl. and it ends at Washing Square Park. This was a nice little park too, so I got a few pictures of it. By this time, not having had a breakfast, I thought it would be good to find something to eat. I moved west along 4th st. until I got to Broadway again. Once I got into Soho (South Houston), I started getting a little turned around (I had just walked nearly 50 blocks). When I got to Canal Street, it was so crowded, I only went about one block on the street and didn't find anything of interest, so I continued on south on Cortland. Somewhere in this area I found (somehow I got to Chamber's St) I found a little Indian restaurant called Jhankar. It was a pleasant atmosphere, and the food was good. I continued on Chambers to get to the east side. I saw the World Financial Center, and eventually found Ground Zero. I took a few pics of what I could see. I did wonder around Battery Park a bit too long, and finally asked someone how to get to the Staten Isl. ferry docking point. I was told it was another 20+ minute walk further south (I was already at the other ferry docking ports and had already walked for over 4-5 hours). He let me know of the Shuttle bus, which the city pays for, which would pick me up and drop me off right outside the area of the Staten Isl ferry. That was a really decent little ferry ride too. 1/2 hour over, 1/2 back. Now it was getting to be near 6 PM and I thought I had better have a little to eat before heading back to 50th st. After walking a few blocks, I realized I was NOT going to make it in time. I looked for a Subway terminal but found none (I had already walked as far as getting back up to the most southern tip of Chinatown. I walked (very briskly) up to Bleecker St. looking for a subway or a cab. I finally got a cab waved down (I am just NOT the type of person that waves down cabs), and we headed off. I called the Bus driver. He said it shouldn't be long, he should get me there in time; and said traffic is a bit heavy here on 4th street. He nearly blew a fuse (and he had just reason too).....but he calmed down and said he'd circle the block and hope I got there soon, and to give him a call when I did. Fortunately, when I finally got back to 50th and 7th, it was only 12 minutes late and he had just pulled up with the bus. Besides the quarter sized blister on the ball of my right foot, and the lunch/brunch I had I brought nothing home with me (well, I forgot about the sunburn on my head.....yeah yeah, I should have worn a cap). All in all, it was nice to see everything......and I will never again walk 70+ blocks just to see everything again. I will become familiar with the subways, as that is about the cheapest way to go (except the shuttle bus). And I am about as stiff as I can for some pictures. UPDATE:More pics UPDATE #2 The few remaining pictures I have left have been uploaded with these to my Facebook album NYC Trip

Best Solar Lights (for Sun Jars/other projects)?

Short: Was wondering if the community had any suggestions for the brightest, longest lasting, most shade tolerant Solar LED lamps? Long: Working on Sun Jar's for little Christmas gifts. Currently using some cheep 2 dollar Solar LED lamps that fit perfectly and seem better than the slightly more expensive one I experimented with, but neither has the endurance to last all night. Anyone found any which performance blew them away? Cost/performance considerations are welcome too.

Top 10 Summer Instructables

Summer is finally here, and so we've selected the top 10 Instructables related to the summer months. From enjoying the sun to cooling off, here are some of our favorites.These are in no particular order, and there are plenty more great Instructables that didn't make the list but could be fun or helpful this summer. Instant Hammock This instant hammock is a simple, easy way to relax under the sun. The directions are clear and the moving images make following the directions a breeze. Fly a Kite This very appropriate Instructable from Kiteman gives you all of the information, and then some, about how to fly a kite. Cozy Boat If kite flying isn't your thing, perhaps you'd enjoy a scenic boat ride. A simple, easy-to-build boat (and its upgraded incarnations) could add a fun element to your summer. PVC Air Cannon For a little more summer fun, you could throw water balloons...or you could shoot them 250 feet with this cannon. I'd go with the cannon. Make Lemonade After a hot day, there's no better way to cool down than with a tall glass of lemonade. Try this, or one of the many other Instructables recipes. Tetris Ice Cubes To cool the lemonade, though, you'll need ice. You can make your lemonade that much better by adding these tetris-shaped ice cubes. LED Picnic Blanket To enjoy your ice-cold tetris lemonade, you'll want to sit outside and bask in the weather. This LED picnic blanket, with hard center serving surface, could be a great option for a drink or an entire meal. Plus, the lights give the blanket nice ambience for a nighttime meal. Solar Lawn Mower Before you can picnic in the grass, however, your grass needs to be mowed. This upgraded lawn mower uses solar power to provide the energy to power the machine. You still have to mow the lawn yourself, though. Beach Cover-Up If you want to look good while you picnic or when you hang around the beach, this Instructable turns an old towel into an attractive piece of clothing. Heat-Blocking Curtains If your house is hot and muggy, being inside will be anything but relieving. You can turn the AC up, but that uses up an absurd amount of energy and makes the electricity bill skyrocket. These simple, cheap curtains could keep some of the heat out and make your house more efficient and comfortable. These are only a few of the Instructables you can use to your advantage this summer. Enjoy the summer (unless you are in the Southern Hemisphere)!

RGB LED Sun and Moon

So, I'm working on this thing, its just an idea right now so I won't delve into it too deep, but I want to use a single RGB LED behind a frosted plexi screen as a Sun and another as a Moon, that will move on a clock motor. Could I get a white with a yellow tinge and a white with a blue tinge with a RGB and a few fixed resistors? I'm just wondering if that would be possible. Would I just set the red and green components to 70% and the blue to 100% for the moon and the red and green at 100% and blue at 70% for the sun? Thanks for the help. I don't have any RGBs so I'm just trying to theorize right now.

heating water using the sun

Hi I want to install a hot water system, as cheap and simple as possible.  The best idea I have found is to connect a new pipe to the main storage tank, and run it the 70 metres to the house, overground, so the sun heats it.  This will work, but it needs a one-way valve at the tank end to stop the hot water entering the storage tank and heating that.  The normal plumbing valves for this need a high working pressure, but our supply has only 2 metres of head at the point of connection.  Anyone know how I can get round this?

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 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

Best solar light, UV LED to use for UV Sun Jar

I'm making a Sun Jar, but I want to swap out the normal white LED for a UV LED. My plan is to spray the inside of the jar with invisible UV reactive paint, so when then LED comes out, the jar suddenly starts glowing a different color. I tried making one tonight, but wasn't happy with the results.  I was using the black plastic Hampton Bay light from Home Depot -;=100068888&langId;=-1&catalogId;=10053&ci;_sku=100068888&ci;_src=14110944&cm;_mmc=shopping-_-googlebase-_-D27X-_-100068888&locStoreNum;=1002&marketID;=48.  It's only powered by 1 AA battery, and the resulting glow from the LED was really dim.  I got no reaction at all from the UV reactive ground marking paint I was using in my test. Any suggestions?

Idea for extended version of "Sun Jar"

After seeing the recent Sun Jar I'ble, I had an idea (not even concrete enought to be a Completable) for an interestingly extended version. There now exist LEDs for infrared, visible red, green, and blue, and near UV.It should be possible, with a mix of small low-voltage constant-current power supplies and pulse modulators, to construct a multiple-LED light source which roughly models what we perceive as the solar "spectrum." I don't mean formally reproducing the raw wavelength distribution, but rather the combination of intensities we see (or measure with a thermometer) in a prism- or grating-spread spectral display.Coupling such a circuit to a solar cell would allow you to build a "Sun Jar" which "collects sunlight" during the day and "releases sunlight" at night. As I said, just an idea...
