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 www.carbonheater.us 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.

Is it normal that when I contact the bare wire to the carbon tape that sparking or arcing occurs? If I use alligator clips as the contact it works fine with no sparks, but the stripped wire sparks and smokes.

It isn't normal you contact the bare wire to the carbon tape, don't do it, please:)

You should make reliable connection then power it only. Alligator suitable just for a test, all of optoins you can find on carbonheater.us in "Connection".

Here's a direct link to that page,

To me, the gist of this seems to be that you always want a current spreader, to give more contact area.

Actually, you could maybe express this idea more precisely, by recommending a number, for a maximum ratio of current to area of contact, like maybe about 1 ampere per square cm (1 A/cm^2). That's a rough guess, just from looking at your pictures.

My intuition would be to make the current spreader from old coins. For example, the pre-1982, US, copper penny, is easy to find where I live. Also I am imagining, drilling holes through the center two of these coins, and bolting the coins together, with the carbon tape sandwiched in between.

Question 8 weeks ago

Does the bare wire only make contact with the carbon tape at one location?

6 connection points marked with white circles.

Also, if an edge of the carbon tape is frayed, would you recommend taping over it or using a lighter to singe the edges?

A lighter... :)

Silver glue is the only way to make it perfect and reliable.

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.

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?

2 more answers

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?

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?
