conductive paint

Do any of you have experience with conductive paint? does it have much resistance?  i'm thinkin of heating car windsheild in much the same way that the rear window is done.  i've cracked 1 or windsheilds while defrosting. seems thermal shock from heat vents on dash are too much. just got a new windsheild.  don't want to break it.

alternative to conductive thread.

Ok guys, so i was finishing up a project with my guitar, and i ended up replacing the strings. so i though to myself... what can these be used for. I decided to use them in a project im working on involving a belt, and regular wire would not work well. So, i weaved the guitar string throughout the belt, like you would with conductive thread, and its very very strong, and also flexible. And since its meant to withstand a beating it should last nearly forever. The strings i found to work best are the 3 smallest ones, E B and G, the others are too rigid to bend as much as needed. in the picture that is the third string, so it is more rigid then the first on would be, and i found it to work excellently for what i needed it to.

Conductive Paint in RadioShack!

Hi everyone, just a quick note to say that our conductive paint pens are now available in RadioShack stores across the US! (and online too) If you're not already familiar with what we do you can think of the material as a paintable wire (but there is a lot more to it than that). Check out our new group page for some of our Instructables or you can take a look at our site for more info about the material and applications. Can't wait to see what everyone gets up to with it!

Looking for electrically conductive glass (or other clear conductive material)

It's been three years since I looked into building myself something inspired by the amazing work of Ingo Maurer. I had a chance to sit at this table (on a bench similarly illuminated!) and it's amazing. It's solid and it's completely transparent. There are no visible wires, the electricity is conducted through the glass. It's by far the most impressive t hing I've ever seen using LEDs.Three years ago when I first looked into it the only option I found was lab glass (I believe titanium oxide coated) that ran about $10 a square inch. Yikes.But materials science moves on. To make my project feasible I'm looking for something with 80% transparency and less than 20ohms/square inch resistance. (And hopfully much less than $10/square). I've read about "FTO coated" and "ITO coated" but can't find anyone who sells it to individuals.Any ideas? Names of possible suppliers, other materials to look into or random suggestions are most welcome.

Hello! I am making a prototype of a force sensitive resistor, and i am using, to old 97%kobber coins, metal sheet and a tiny piece of conductive foam that i got from a tv-repair shop. The setup is not very good, but its a start, and i am planning the next move for better results... Now... I want some decent understanding of how the readings work, and why I get these results.. First test, are written with black, and and as you can see it, has the same amount of space between 0-1kg and 1-2kg, but 2-3 and 3-4 changes to a very small space? Why is that? Second question is, that i have used the x10, to read larger forces. 0-2,5kg and 2,5-5kg has same amount of space. Will the space decrease too, when getting further up the scale too?  - I know the conductive foam has its limits too, but just to be clear of my readings. Thanks in advance!

Need help with capacitive button cover for Xbox One.

So I hate capacative buttons.  I work for Microsoft as a game dev and we all have Xbox Ones.  They have the worlds most sensitive capacative power button.  We regularly accidentally turn our boxes off with a slight brush of the hand, bumping a coffee cup that was too close or brushing a controller cord against it. I have been trying to build a button cover.  One that will still turn it on and off with an actual press rather than a light glance of the hand.  I have had no luck so far and have been learning about conductive surfaces along the way. The original plan was to use conductive rubber and some scotch double sided tape.  The tape I am using is a clear rubber and has a mm or so of thickness to it.  I bought some gasket punches and punched out a button about the size of the capacitive area of the Xbox One power button, around an inch, and then another in the tape.  I punched out a smaller center hole in the tape to turn it into a washer, and stuck it onto the button and stuck it on the Xbox.  In theory you have to press the button in to make contact with the capacative button to turn on or off the Xbox.  But alas, it still turned on with the slightest of brush still.  I stacked the tape up to four times.  I tried foam mounting tape.  Alternated tapes, stuck electrical tape inbetween, and still the same thing.   On their own the tapes wouldn't turn on the button when tapping them to, but perhaps there was enough distance when touching holding it length-wise rather than flat against. I figure the electricity must be flowing over the non conductive surface and still going to the button.  In the office with all the EMF I seem to be averaging around 3v to the touch.  I have a grounding mat at my desk that when I make contact with takes me under a volt, to around 0.3v but that doesn't make a difference. So I figured I needed a bigger insulator.   I got some larger machine washers where the hole seemed larger than the capacative area, punched another larger button out of the conductive rubber and glued it over the hole.  Using double sided scotch tape I stuck it to the Xbox.  The same thing as before happened.   Even touching the rubber only was enough to turn it on with a light bump.   I figured I needed a ground.  I tried removing the grounding cord from my mat and holding it against the rubber of the button.   It seems slightly less responsive but still turned on easily.   I tried running copper tape along the side of the Xbox to the button to see if that would draw away the charge, but it did not. Taking my rubber washers I used my multimeter to see if they were conductive at all.  They did not seem to be.  Setting it to measure the volts in ac they are picking up about 0.03v, but so is just the air.  But the rubber rings will turn on the Xbox when I hold them though the thick double sided tape will not. Does anybody have any ideas on how to get this to work or what I am doing wrong?  I will admit I don't know a ton about this stuff.  But I don't understand how these materials can turn the button on.

Thermal conductivity of two welded plates?

I am in the process of building a wood stove (details on FE Blog) mainly from scrap metal, but I have got it into my head that a stainless steel hotplate would be nice. I wanted one 10mm thick, round with a diameter of 390mm. As it turns out 6mm seems to be a bit of a threshold for stainless, and anything over has to be laser cut or similar and is loads more expensive. Like £80 is the cheapest I can find it.  Anyway, one solution would be to buy two 5mm thick plates and weld round the circumference - that seems like it would work out quite a lot cheaper. The question is how would the thermal conductivity be affected by the tiny gaps which would inevitably remain in the centre (the two plates will never be completely flat)? Is there some kind of thermal paste that could mitigate this, which is very heat resistant? If so how would it deal with being superheated by the welding, and would it contaminate the weld? And lastly - this got me to thinking about copper bottomed pans - how do they bond the copper to the stainless steel (google is failing me- or I am failing google with poor search terms)?? So 3 sort of related questions: 1.Welded plate- big conductivity problem or naught to worry bout? 2.Super high temp. thermal past  - would it help? 3.How are pans copper bottomed anyway?? Thanks, Bongo

Electrically Conductive Plastic: a general discussion.

I find i have an odd set of interests. Specially with regards to this forum.  I'm interested in electrically conducting plastics. I've been hitting the Wikipedia pretty hard looking for information on the topic.  I've found a couple of interesting articles: My main reason for pursuing this as of late is because I think electrically conductive plastics offer a way to create high efficiency photovoltaic cells on the cheap (least relative to growing pure Silicon crystal without oxygen contamination).  Azodyes, which are popular doping agents for current thin film photovoltaic cells  can be linked directly to the organic back bones of the polymers, and i think this will make the conversion of photons into electrons more efficient. There's other organic compounds (specifically i'm thinking of metallocenes which can be used to generate positive valences, also known as "holes" within the molecular structure of the plastics) which can be used to dope an organic solar cell, but azodyes are the most obvious. Anyway... gonna hit up google. if any y'all have ideas post em up.
