Step 4: Fabric Pressure Sensor

For this component you will want to follow the detailed instructions posted in this Instructable>>
Idea: Buy 3 of these <a rel="nofollow" href="http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=227993">Solar panels</a> and tape them to the fabric with double sided tape. Wire each panel in series with each other (positive end of one with negative end of the other). Buy 6 1.5V rechargeable nicad batteries (might be a bit heavy), and wire them together in series as well. Put on a 3 position switch to switch the batteries between charging off the solar panels and running your stuff. Voila! Now your shirt generates no dead batteries.<br/>
Well then it would not be a waste of energy if its solar powered lol
It would be a waste of energy if it ran on coal or gas
Well they probably charged that battery using energy from a coal or a gas power plant. And she mentioned that she felt bad wasting energy, so I gave her and alternative :)
No,it's not charged,it generates by chemicals ;)
therefore you waste chemicals. Even better! Save the oil and stuff for muscle cars.
yeah... By the way you wasted energy on this Instructables that is on wasting.LOL
"Wearable Waste Of Energy" ...? One word... No. Energy should be conserved. Not wasted?
Of course! In a way it is just the title of the project, because.... what it the use of lighting up an LED on my sweatshirt or running a vibration motor? But of course in a further development sense, there are uses for these things.
Still, the word is NO. That 9V is going to end up in a landfill, where it will slowly ruin my world. Thanks for wasting.
when did it become your world?
It's your world too kid. Stay focused.
Oh grow up.
you grow up
Wow. The bickering can not stop.
Loool, people on this website moan about everything! Be happy, it's cute!!
technically yes it is a waste of energy but is that 1 9volt gonna be the cause of the end of the world?? its a L.E.D (a light emitting diode) they do NOT use a lot of energy sure after a while it will add up but its still not gonna destroy the world because of 1 9volt
So, wait... Your world's a landfill? Probably isn't the best analysis, but it also raises a lot of questions... And answers.
Exactly. So the point is to NOt follow this Instructable but come up with better things. Solar cells are an option.
I agree...bytheway where you get that golden fabric u use as connector lines?
It is stretch conductive fabric from LessEMF. Check the first step for the list of materials and links.
The waste of energy is small, especially compared with the experience gained from working with these tools and materials. This is a stepping stone to Greater Things!
I guess. But still. I felt bad having to use a 9V battery to power an LED and another 9V battery to power a 3V vibration motor, just because the conductive fabric sucks so much power. But conductive fabric is cool and you are right, it will surely lead to greater things!
Have you tried using conductive thread? I think I recall testing and determining that the thread has a lower resistance than Zelt, at least; but I could be remembering that wrong. The stuff I use is intended for repairing fencing outfits, I get it from Lame Lifesaver at <a rel="nofollow" href="http://members.shaw.ca/ubik/thread/thread.html">http://members.shaw.ca/ubik/thread/thread.html</a><br/>
Actually the strips of stretch conductive fabric have less resistance than the thread. Especially since the fabric is stretchy and the stretchy stitch goes zig-zag as well as doubles back on itself, using more thread - more resistance. But in the future, maybe, yes. And thanks for the suggestion! Sparkfun now also sells spools of conductive thread >> www.sparkfun.com
One tip, if you put multiple threads as one line it'll lower the resistance, like have five threads to each leg of the LED instead of one, it'll help to some extent though at the cost of either flexibility or subtlety...
Plusea, you so crazee! I think it's a great USE of energy. Shooby needs to take a re-cycled pill n chill. Perhaps epaulettes of solar panels would be in order, or one of those pith helmets with a built in solar powered fan, with Faraday enhanced shoes that absorb the energy of each step, and link em up?
Einstein theorized that energy can be be neither created nor destroyed. Energy resources are a different story. I'm pretty sure Al Gore got a Nobel Peace Prize, though. Also, I think it's a responsible attitude to understand what pollution is, and then not do it. I also think this is a cute project.
Amen Brother
Its a joke against all that Global Warming stuff
Personally, I think this would pass as extremely fashionable.
i agree. and i think your name is awesome.
Thank you! All my friends say that, too.
the fashion industry doesnt make a lot of clothes that actively use electricity though.
almost everything you do uses electricity. i meant that the energy they "waste" just doing business. and most of their products probably never see production. i'm sure it takes a lot of time and energy to make people look good. there are aspects of industry that most people couldn't fathom. and all of that takes energy to run. so if making your own clothes look a certain way is a waste... just imagine how much the fashion industry wastes.
True. A monstrous amount of energy going to waste. Such a shame.
cool project. end of story.
Forget the landfill, this thing will only be on, wasting power, while this person is showing the sweater off to others(not long). It's not like it's going to be on 24/7. This is simply an experiment with wearable circuits. Efficiency can come later, experience starts now. Great ible! I wonder... what about that really thin "enameled" wire used for making incuctors and transformers?(more than meets the eye) Granted, it'll wear out after a bunch of bends, will short out against whatever it can, and is more intrusive to wear than conductive fabric, but it can carry much more power at lower resistance. Speaking of resistance, maybe, during wintertime, this idea can be taken further with a resistive element T shirt that warms you up! It was my idea first! But go ahead and build it, and make ibles! Bwahahahahahaaa! Screw the planet, I wanna wear an LED! Speaking of LED's, maybe you could do that invisible face IR hat idea and expand it to make your whole body invisible to cameras! Speaking of cameras....
just a small side note... the enamel wire won't short out against whatever it touches... it's covered in insulative enamel. and running two from a battery to an led wouldn't be enough to become intrusive, i don't think. and i bet it would last a very long time. long enough that by the time it does wear out and break somewhere, you can just sew in a new run. i think, when i do this, i'll do it with enamel wire and see how it works.
Good point.
i like it. and i don't think it's a waste of anything. if this is wasting energy, then the entire fashion industry is wasting tons and tons of energy. but it's not a waste because people want their clothes to look good. if you like it, it's not a waste! and if you learned anything, or if anyone else did, then it's the opposite of waste!
what's interesting in this project???? seriously we could do the same with a battery a led and a sofa and make a "energy waster sofa" !!!!
dude, you're a genius! i don't think i would have ever thought to do this to furniture, for some reason. you have transformed my living room. thank you!
I actually kinda like that idea. Thanks!
I really like your creativity! and the sense of fun!!!
I love it Hannah! and the discussion about conservation of energy haha... Waste MORE energy.
a battery or two here or there isnt going to make a huge difference.<br/>stop complaining and enjoy live.<br/>in 10, possibly 20 years we're going to have started using hydrogen fuel cell cars and stuff like that.<br/><br/>get over it =]<br/>
Forget the landfill cracks. This is inspiration. I really love the conductive fabric idea. This explodes the possibilities. Thanks!
