DIY Carbon Heated Blanket





Introduction: DIY Carbon Heated Blanket

About: DIY carbon heated clothing.

Very expensive to warm at night the whole apartment when you sleep in a bed. Much better to save money on heating and warm a bed only. So I decided to make a heating blanket.
As the heating element I used the carbon tape. It looks like a thin, soft cloth and not interfere in a bed.
The carbon tape can be sewed, but instead it can be simply glued. Because of this I did it in just 1 hour!

Step 1:

To make the blanket I took 2 pieces of inexpensive fabric

6 feet of flexible wire
20 feet of carbon heater tape 15mm from and now on Amazon

silver conductive wire glue paste, female plug 5.5 mm and iron-on no-sew hem tape. The desired temperature can be determined from the table.

Step 2:

Cut a piece of fabric length of 5 feet (150 cm).

Put carbon tape zigzag. Zigzag shape can be any that you like.
Under the carbon tape to put iron-on hemming web tape. Gently press the carbon tape with an iron that is stuck to the fabric.

Step 3:

Glue the wire to the carbon tape using silver conductive wire glue. Due to the silver glue, contacts will be very thin, very small, will not interfere in a bed. These contacts can be easily and quickly done, and they will be very reliable.
Squeeze between two layers of carbon tape some silver from the syringe, insert the bare wire, squeeze glue place until the glue is completely dry.

Step 4:

Put strips of no-sew hem tape along the entire length of the wire. Fold the edge of the fabric and press iron.

Step 5:

Put contour fabric no-sew hem tape.
Cover with second piece of cloth and gently press the iron over the whole area.

Step 6:

Solder the plug. I connect it to the power supply from my laptop. Work is finished.
Blanket ready:)

Step 7:

Blanket consumes about 40 watts. This power is enough not only for home beds, but also for a sleeping bag in a campaign. Then I connect the blanket to a battery 12 volts.

Blanket is a comfortable shelter, but it can also be put on a mattress under a sheet.

Step 8:

Blanket can be embedded in a duvet cover, but also you can be covered by it alone.

Let my warm save you from danger,
And you'll never cry,
Close your eyes and sleep, my angel,
Sleep, dear, rock-a-bye.

During the day I use it to cover my feet in a chair.

7 Questions

can this be used for dogs? also can you plug it into a power outlet?

Yes, we used it not only for dog but even for cat and chiken.

Carbon tape can heat at any voltage from 1 to 1000 or more but using power outlet required some knowledge from you.

Instead of no sew hem tape, can I sew instead?

Yes, it looks like a normal soft fabric. You can sew and wash it.

First of all - amazing! I need to make a sweater/upgrade a jacket for my wife. I am a complete newb when it comes to electricity. Would I be able to use a usb battery pack as a source for about 10 meters to sow into arm sleeves, chest and back?? Price is not a problem if there is a solution.

at what temperature carbon strip will heat enough to heat up gloves?


The correct question is what power we need and the answer is we need about 5 watts per glove for a moderate cold and about 10 watts for a strong cold. Branded heated gloves usually have about 70C but never reach the maximum and you should make near the same. You can see that idea everywhere, for example a kettler heat water up to 100C only but without water (and thermal switch) it could melt even metal.

Answer form doesn't work correctly, sorry...

Hello Sir! am going to make heated Gloves using Carbon strip. At what temperature carbon strip will heat enough to heat up Glove?

What should you do if you have no access to electricity?


You can use a power bank. You can use the most types of batteries including rc models battery, sla battery from UPS Computer Back Up, etc.

is there any other chargers you can use to charge the blanket?


The most of notebook power adaptors will be perfect.


Hi! I am making an electric blanket as part of a project for school, however the link you have (for the type of flexible wire to use) is dead. Any suggestions as to what would work best?

How warm does this blanket actually get?? It seems like if it gets to hot, and you use thin fabric then you could burn yourself.....

2 replies

As you can see on IR photo it is about 41 C. I need a high temperature to use the blanket on a hike. Usually I use it with a dimmer to adjust the temperature and increase the running time.

Oh. Alright. Thanks for clearing that up for me!!

could you leave me a email so that I can contact you.

hi i have send some email to you but is seems doesnt work.

Question: say I had a piece of carbon fiber tape 30mm wide. Could I cut it lengthwise into two 15mm wide pieces and have it still work? Will cutting the weave make it not function?

1 reply

No, you can't, it will fall apart just you cut it.

Thank you for the wonderful tutorial. In my case the carbon tape did not heat up. Can you please help?

Yes, I can.

The carbon tape just a heater. It always work when you connect it to
power. So the problems could depend on power supplay, connector and
connections only.

What is the carbon tape lenght?

What is voltage?

On your photo I cannot see connection points. Could you, please, make a macro photo of connections.

The voltage is 12V

I'd grab a multimeter and check if the supply voltage is good. If it is then I'd connect it between the power supply and the heating element to see whether any current passes through. If it does (but it's too low e.g. in the ranges of mA or tens of mA) then probably the resistance of your carbon tape is probably too high for the given voltage (it doesn't push through enough current through the tape). If that's the case then you'll probably need some other heating element with less resistance (shorter/thicker/wider carbon tape or some nichrome wire instead) I'm afraid.

Hey Ryia,

You may not have enough resistance for 12v, you might try a lower voltage. Maybe a 3.7v 18650. You will need enough amperage too, a few AA's will not work.


then you can buy an electric blanket, inspected from the UL for $17.35 at Walmart, 9 heat settings. auto start, auto off. You donkeys won't be happy till you burn a bed down.

Hi jdrego1,

What You state is correct we could go to the Walmart web site and have thing shipped to our door in 2 days for $9.95.

However, I infer that you think that spending more money with an unsure result is a bad thing. Further I infered that you think taking a chance of "burning down the bed" would stop these types of efforts.

If my inferences are accurate, in this you are greatly mistaken.

People on this site are makers, artists and other such rabble. They think a burnt finger, or running out of a smoke filled room is a part of the glorious process.

If this sounds crazy to you, I recommend you spend more time at the wamart website or othet place of your choice.

Instructables is not the place for you. It is full of new and dangerous things and ideas

Yes, be afraid, be very afraid
