    My main idea was to make a modular system that can be used with different clothes. I made two identical heating panels that can be combined into a single vest or attach to any outfit.

    Each panel has 2 meters of carbonribbon. Chose the maximum width of the tape to provide a very even heating. Size panels 34 x 42 cm, since it is better suited for the size of my clothing.
    In each panels tape connected in parallel 2x1m and has an independent power button.. It takes about 3A under 12V (36W) for each one or 72W together.

    You can sew wire to carbon tape to make a good and flexible connection. The contact place shouldn't be hotter than the tape itself. If not you must increase the contact area. Sewed contact very flexible.

    Contacts may be sewed by sewing machine or just wraped with a wire.
    But as you can see sewed contact is colder than the tape itself (left contact).
    Wraped contact (on the right) is more hotter than tape.

    On each panel sewn 4 pieces of Velcro . Now I can combine them into a single heated vest . A bit like a bulletproof vest[​IMG]. It's very soft and thin.

    Due to Velcro this vest will be comfortable to wear for a big man or a small woman.

    Each panel can be used independently with any clothes.
    On the inner surface of conventional jackets I sewed 4 pieces of Velcro.
    Now I can at any time fix the heating panel on the jacket and make it a heated jacket.

    It is fully warmed up to 40 degrees in less than one minute. By touch carbon is a little bit like a loose weave silk. It's very soft but strong enough. Because of big length it provides uniform heating of body.

    When are you going to market these heating panels ?????
    This is a great and cheap idea that could be a sailable item.:ear

    Very neat idea. Couple of questions:

    1.) Where do you find said "Carbon Tape"

    2.) What is the cost?

    3.) Do you use some sort of Heat Troller with it, or how do you power it?

    4.) Could a old jacket be used instead of the panel, to basically make a heated jacket "liner"?

    Thanks! Again, very interesting idea!

    Waterproof? Just for that "there was no rain forcasted" factor. Just hope there's nothing to short the system.

    I know the other styles use hook-up wire which is still shielded in a silicone coating.

    However, this setup definitely looks like it'll keep you warmer!

    1. "Carbon heated tape" on Ebay.
    2. $ 5-15/m
    3. "dc motor controller" on Ebay ($10-30)
    4. Yes, I think so.

    I wonder why it, the tape, appears to only be available (or at least all I found) from the Russian Federation??

    Well, in my first heated jacket was only 50 cm of tape, it's about $4,5
    A longer tape provides more uniform heating. We can make a very inexpensive vest, but the area of ​​the heating element will be small, less comfort.

    I'm not sure shorting is an electrical consequence with resistance wire which this basically is. It's spaced so much that I don't see it happen, but I guess it'll simply get hotter because the length if shorted due to the short.

    Didn't know there was a fabric version to resistance wire. Might have to do something myself. :clap:clap

    Just wondering as to if the carbon used in the "tape" is something special or is it just carbon fiber fabric?

    Of cause it's just a kind of carbon fiber fabric.
    All of them are conductive. Some of carbon fabric is more strong but less flexible, you can use it but its not so comfortable to wear and doesn't wear-resistant. This one designed especially for heaters, its more thin, soft, flexible, not so easy to wear-out.

    No, it doesn't. This material provides surface resistivity of 10 <sup>5</sup> Ohms per square. "Provides excellent static discharge and grounding" only.

    For heating we need about 5-100 Ohms.

    Thanks for that. I have been wracking my brain trying to figure it all out with carbon fabric. So I will end up using this for my gloves and toe wraps. End up using the ol' fashion 30 AWG copper for the jacket and pants due to cost.

    I still wonder what they use in the floor heating materials then. Or even the commercial versions of yours.

    Shenzhen nice writeup! Why not use a whole sheet instead of tape?

    I'm guessing the wires would have to be hooked up on opposite ends?

    Is this the same stuff Tour Master uses in their Synergy products?

    If so, I will attest to the effectiveness of the heating. My Synergy vest is rarely set above LOW and only occasionally on MED.

    Very nice writeup. I'd love to put this on some Silk glove liners and power them from the vest.

    Any ideas for push button temp control for dialing it in?

    As is with wires, the larger your cross section for electron flow becomes, the lower your resistance is. Do you understand the point of having resistance here?
