Picture of DIY carbon heated blanket
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:

Picture of
To make the blanket I took 2 pieces of inexpensive fabric, 6 feet of flexible wire,
20 feet of carbon tape 15 mm from, 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:

Picture of
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:

Picture of
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:

Picture of
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:

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

Step 6:

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

If you were to put this inside a metal, titanium, or another type of metal, 3 foot long, 1 inch wide, cylinder would there be any type of complications of it getting extremely hot or melting the metal? Also is there any way of making it waterproof and without melting the metal?

Again and again, I repeat that the carbon tape is a common heating element. It works in exactly the same way as nichrome wire, or any other heating element. Heat transfer of carbon tape at temperatures of 30 - 300 degrees is only 5% higher than nichrome ( but at 500 degrees - 25 % higher).

The main advantage of the carbon tape is its resistance to repeated bending.

And yes, you can put the tape in any metal, but between the tape and a metal must be some insulating material.

To make the carbon tape waterproof you can cover it with any silicone sealant.

Alright thank you for your help! That makes a lot more sense!

Very cool project!

Question: Could the carbon tape idea be made waterproof and used as a seed starter heat mat placed under seed trays?

Shenzhen (author)  oenopion7 months ago

Yes, you can glue the carbon tape into a PVC film or sealed with a silicone
sealant. But it is much better to use the tape in clothes and put under
the seeds some nichrome wire into a tube.

The carbon ribbon heating element is the same as any other heater. The main advantage of the carbon tape is that it can withstand repeated bending.

Okay, that makes sense. Of course, now I want to make a heated cloak for myself! This has also given me an idea to make a heated exterior battery case for doing winter night timelapses. Cool stuff.

I love your carbon heater projects. I had the idea of making a heated comforter or mattress cover after seeing your last instructable, but looks like you beat me to it lol. Keep up the good work.

Thank you. Very nice to meet likeminded person.
By the way, in the near future we hope to present you a new secret project: "... proof vest".

We are working on it:)

I love this carbon tape!

We made a very good carbon tape Taser proof jacket:

I am not familiar with carbon tape, but this looks like a good idea. Is it safe? Is it efficient energy-wise?

As far as it disipates heat, sure it's not efficient. I'm also concerned about safety... i'd place some current limiter circuit or so, i don't want to be the human torch :D

Besides this, i like the idea and the execution :D

Oh yeah, I definitely lovethe idea! I'll be ffollowing these fine instructables.

Yes, on the IR-camera all
heating elements look like a light bulb:)

I showed how to make a base,
a central element of the design. Of course it can be improved.

From the viewpoint of energy
savings, the most effective positioning the heating element on the
mattress under the sheets. Then more heat remains under a blanket.

If you still need a blanket,
then to retain more heat you need to use a thicker outer fabric,
providing better insulation properties, for example, thick wool,
Thinsulate, and so on.

Using the AC adapter from the laptop
is convenient because there is already a short-circuit protection.

For added convenience, this blanket I connect via remote RF
dimmer. This allows you to adjust the temperature, turn on or off at
the right time. A little later I'll write about it and show pictures.

I had never heard of carbon tape. This is all very interesting. I'll be following your projects now.

Thanks for sharing.

The carbon heater is the most energy effective heater. Just like any other heating element, it requires compliance with the rules of safe operation.
One of the main advantages of the carbon tape is its resistance to repeated bending, which greatly increases the safety of use.

Good to see your projects, promoting carbon heating. The idea to warm yourself instead of warming the room, is the biggest chance/challenge in reducing energy for mankind. Go on and make an overall, heated/powered by battery.

Dear IamWe,

Thank you very much for your support. We will certainly try to do something interesting again.
