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

Hi there, I'm interested in creating some of the projects reusing capri sun pouches but would like to know if there is a need to close/ seal the straw hole on the pouch. I was wondering if water or dust will go in it once the pouches are sewn together.  Thanking you for the response, Mina.

GMO sun flower seeds, how can I tell? Answered

Hi fellow instrucablers, I planted some sunflowers a while ago and recently I collected the seeds from the flowers and replanted them.  The original seeds were from a packet which I threw away.  I've planted the new seeds and it's been a week and the haven't sprouted, I'm not sure if I was really unlucky or if the seeds have been genetically modified in order for them not to grow new plants.   I still have some seeds left over so I was wondering if there was anyway to tell if they have been modified somehow.

Itchy sunburn madness!

 Since I live in northern Michigan, I pretty much hang out indoors for a majority of the year due to ''Frozen Winter Hell''. It's been sunny these last couple of days, and I managed to bake my paper white skin :( The only reason I'm able to even type this question is because this burn is located exclusively on my neck. Last year my itchy sunburn covered my whole back...it was like being stung by 10,000 killer bees for 3 straight days...my agonized screams certainly disturbed the neighbors. I'm sure some of you have experienced the whole itchy sunburn madness...how have you dealt with it? Oh, and I drew a picture of the sun for inspiration:

Why do I get a voltage drop from my solar panels....? Answered

I am building my own solar panels and installing them as I go. So far I have mounted three 70 watt panels. I have a twenty amp controller and a 1500 watt pure sine wave inverter. With the array switched on and connected to the batteries (8 x12 volt 134AH) via the controller everything seems fine with a steady 13 -14 volt charge coming through. But when I connect the inverter the PV volts drop to around six and seven volts....The batteries are wired in parrale but not directly to each other. Instead I connected them to a buss bar hoping for equel drain and charge... I then connected the wires from controller and inverter to the bars... I thought this may have been the problem so swapped them all around having the controller wires to the battteries, then the inverter directly to the batteries... It made no difference and the voltages remained the same....I am hoping now that the reason maybe that I do not have enough panels to power the system and as I add more panels the voltage will rise...... l Any thoughts on this will be very welcome.....?

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

A sunscreen that keeps you in the shade all day long

I have been thinking about a suncreen that will keep shaded all day long. Rather then to move along as the sun changes position during the day, why not move the suncreen so that it always shades the same spot ? To that end, and after some thinking the idea of a movable abstract tree like shape which projects shade on the ground, was come up with. It would be able to move, let the wind pass trough, and because unlike traditional suncreens it would not be a parasol, it would give shade but cooler wind is also possible. Question remain though. Ho do you know which shape will give which shade ? As the screen would have to automove, a GPs with clock and arduino/wire would be needed. In a later step how to deal with excessive wnds would have to be included. There is also a possible cantilever mecanism and the weight of the whole thing. Also possible is to add a solarcell for the energy. As when one side is giving shade the other is pointing towards the sun. So some of the mecanism for it could be used for other things. I wondered if there is some kind of formula, algortirhm where you put height, surface area , shape/coordinates position of the sun, season in it, and the coordiantes of the area which should be shaded, and then run or show or find which shape would work best, but also to use in the arduino/wire. The shade could be be like big leafs that cover each other, like thick crosses, which allow the wind to move through, or other things. Please let me know if this is not so clear.

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.

Currently, I use my DIY lamp with a USB Power bank (5,2V , approx. 50k mAh), but my lamp contains 39 LEDs, and they are ultra-bright LEDs, so they drains the battery fast. So I thought if I connect some solar panels to it, I can charge power bank during daytime.
