diy heated clothing kit
The pattern made from some factory vest.
6 meters of carbon heating flex tape from www.carbonheater.us and now on Amazon placed on back and both sides. 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.

Tape connected in parallel 6x1m. It takes about 3A under 12V (36W).
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. The best idea to place wire between two layers of carbon tape.
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.
Carbon tape can be extended. Place two pieces of carbon tape together on each other with little overlap and sew it on. As you can see the connection place is not hotter than the tape itself.
Sewed contact very flexible.
It's powered by 6x18650 connected in parallel (2x3).
I use it with an adjustable controller.
