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.


It is fully warmed up to 40 degrees in less than one minute.

Step 1: Sewing

Each panel has 2 meters of carbon heated tape (www.carbonheater.us). 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.

Step 2: "Soldering"

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.

Step 3: Connecting

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.

Step 4: Using as a modular system

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

Step 5: Using as a modular system

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

Step 6: Using as a heated module

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 a jacket and make it heated.

where can i find the tape?

"Carbon heated tape" on Ebay or www.carbonheater.us

My mother has a sewing machine and helped me make this last weekend. I have yet to wire it up to a plug usable in either my bike or car but i'm working on that today.

AWESOME!!! Great idea ! I need one of these up here on this job in Michigan!
can you make me one ?

I'm not a tailor, so I need a week to make it. It will be very expensive vest:)
I think it will be better and cheaper if you can find a seamstress. Just take the tape and Do It Yourself.
sounds like a idea! thanks for the thought !

Cool idea but a question or two What gauge wire do you use to make the connections and is it the same sized wire to make the parallel connections?
Shenzhen (author)  Rusty1014 months ago
We can use any wire we have. For clothing it's recomended an ultra flexible wire (multi - stranded) cause they are wearproof. The diameter depend on the current.
We can found the correct in AWG table (here for example: http://www.ken-gilbert.com/techstuff/AWG_WIRE_TABLE.html).
The power consumption and amperage depend on you only. Here some examples below:

1 foot - 24,86W (12V); 31,5W (13,5)
2 ft - 12,4W (12V); 15,7W (13,5V)
3 ft — 8,3W (12V); 10,5 (13,5V)
4 ft — 6,2W (12V); 7,8 (13,5V)

If connect 1ft x 2 in parallel it will be 24,8W +24,8W = 49,6W (12V); 31,5W+31,5W=63W (13,5V)
If connect 1ft x 3 in parallel it will be 24,8W x3 = 74,4W (12V); 31,5W x3=94,5W (13,5V)

2ft x 3 in parallel it will be 12,4W x3 = 37,2W (12V); 15,7W x3=47,1W (13,5V)
2ft x 4 in parallel it will be 12,4W x4 = 49,6W (12V); 15,7W x4=62,8W (13,5V)
2ft x 5 in parallel it will be 12,4W x5 = 62W (12V); 15,7W x5=78,5W (13,5V)
2ft x 6 in parallel it will be 12,4W x6 = 74,4W (12V); 15,7W x6=94,2W (13,5V)

3ft x 5 in parallel it will be 8,3W x5 = 41,5W (12V); 10,5W x5=52,5W (13,5V)
3ft x 6 in parallel it will be 8,3W x6 = 49,8W (12V); 10,5W x6=63W (13,5V)
3ft x 7 in parallel it will be 8,3W x7 = 58,1W (12V); 10,5W x7=73,5W (13,5V)
3ft x 8 in parallel it will be 8,3W x8 = 66,4W (12V); 10,5W x8=84W (13,5V)

4ft x 7 in parallel it will be 6,2W x7 = 43,4W (12V); 7,8W x7=54,6W (13,5V)
4ft x 8 in parallel it will be 6,2W x8 = 49,6W (12V); 7,8W x8=62,4W (13,5V)
4ft x 9 in parallel it will be 6,2W x9 = 55,8W (12V); 7,8W x9=70,2W (13,5V)
4ft x 10 in parallel it will be 6,2W x10 = 62W (12V); 7,8W x10=78W (13,5V)
4ft x 11 in parallel it will be 6,2W x11= 68,2W (12V); 7,8W x11=85,8W (13,5V)
4ft x 12 in parallel it will be 6,2W x12 = 74,4W (12V); 7,8W x12=93,6W (13,5V)
could be great for giving a piece of your mind to anyone spying on you with an IR camera
Dang, I do not want 3A going anywhere close to my body, but I would love to make myself some heated socks this way! My toes are always chilly when I'm sitting at my computer, and 40-degree footsies sounds just divine... :-)

Dear jjdebenedictis,
Especially for you we've just tested it:)

:-D Looks lovely and warm!

Thanks for your interesting instructable. Carbon infrared heating is the future of heating. Whether as panel on ceiling and wall or as floor fabric; it is radiant heating. As such it will be a supplement to convection heating, only being much cheaper to purchase and use. I was busy with a project for heated clothes till I discovered that the prizes are dropping drastically. I bought a vest with 2 heatpads for 30 euro. Each carbon pad using 700mA. I use a small lead-gel battery for hours of intensive warmth. This battery I carry on my trouser belt.

What do you use as a power source?
Shenzhen (author)  emiletich6 months ago
Bike's battery/generator when onboard or 18650 Li-ion battery (2x3 for each panel) when walking.
