Picture of DIY carbon tape heated vest
diy heated clothing kit

The pattern made from some factory vest.
6 meters of carbon heating flex tape (www.carbonheater.us) 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.

I like this. Have you tried snap buttons instead? That way you can disconnect the connections.
Shenzhen (author)  NWBrewer1 year ago
You can see the battery connector and a power button the same as placed inside right there.
Can you wash it?
Shenzhen (author)  NWBrewer1 year ago
Yes, I can wash it without any problem.
I received the tape in the mail (44 cm), and cut a 1m strip. Only 500 mA went through it, with a 10V drop, when run through a 12V supply (8 AA (1.5V) in a pack). No heat generated. Is there a mistake in my prototyping configuration?
Shenzhen (author)  daniel.foster.54584984 months ago

Please look at the picture. Carbon tape consumes 1.59 ampere and heated to a temperature of 50.6 degrees Celsius at a supply voltage of 12 volts. Tape always works, it can not work poorly or incorrectly, as it is a conductor of electricity with constant resistance. If you have a tape consumes little power and is not heated, so poor
contact between the tape and wire, or the power supply does not provide
enough voltage and current.

1. Please show a picture of your product, which can be clearly seen the point of contact of the carbon tape and wire.

2. What is the voltage across the wires at the point where they connect with the carbon ribbon?

maybe it was the contact point. I was using small clips on one edge of the tape. When I ran the wire around the tape, as in the picture, I got 7.75 V @ 1.3A. The tape was almost equal to my skin temperature. With insulation and proper contact points, I can make a better heated jacket. Thank you for the explanation.

I recommend that you replace the AA batteries with rechargeable batteries 18650. Every heater consumes a lot of energy and AA have to be replaced frequently. It's expensive. Furthermore, at a current of 1.3 Ampere AA batteries have a large voltage drop, so the the tape is not heated sufficiently.

Created a terminal end for joining 22ga wire to the carbon tape... and this happened [see pic]. I have a series of 4 carbon strips ~10" in length and this was the 2nd strip... Has this happened to anyone else? Or how do you prevent this from happening?

Shenzhen (author)  ToddM27 months ago

To answer your question you need to know:
1. Voltage, current
2. Photo the other side of your contact.

Could you provide, please.

ToddM2 Shenzhen7 months ago

We're running 12V - 1.5A

Shenzhen (author)  ToddM27 months ago

We need to see how the wire placed on the carbon but it closed with that red fabric. Could you open it?

hairyogre8 months ago

excellent project...what width tape are you using here?

Shenzhen (author)  hairyogre8 months ago

15 mm.

Hi Shenzen, received tape yesterday and made a similar jacket to this one. I am now nice and warm thanks to you. I will be buying some 44mm to try out in the New year. Really excellent project and it really works fantastically well. Best project on this site. Well done, you are my Hero!!!

Shenzhen (author)  hairyogre8 months ago

Thank you for the good information.

Now you could make some instructables about, get "Popular", and we send you 10 meters of carbon tape for free! Every one can be a Hero, just do it!

can a 3s 2200mah lipo pack be used as power source and do i need a protective circuit? (due to the nature of the lipo packs, they are tend to burn or bubble)

Shenzhen (author)  Bülentİ9 months ago

That pack has about 20-25 Watt of power. It's not much but of course you can use it.

Protective is very usefull and recommemded.

Do you have a sketch of the electrical connections on the vest, I am not clear as to how this is wired, it appears that the wiring is connected in multiple spots on one continuous ribbon....
Shenzhen (author)  Navy_Chief1 year ago
The tape is divided into 6 equal parts1 meter of each. Parts are wired  to obtain 6 parts in  parallel. The first figure below shows the wiring on the vest. The second figure shows the equivalent circuit.
locozap Shenzhen9 months ago
2 questions on this. In step 7, the positive and negative connections appear to be in the same location at the top of the vest. Are the connections isolated from each other right there? Also, the 6 - 1 meter sections... Are they separated, or is it a continuous strip with power connections in the middle? Thank you.
Shenzhen (author)  locozap9 months ago

Yes, it's a continuous strip with power connections in the middle.

It is just one connect with two wires. Sorry about different colors.

mnørgaard9 months ago

This looks awesome. I have a quick question about safety:

How do you insulate the tape?

Can you touch the tape when power is connected?

Shenzhen (author)  mnørgaard9 months ago

Yes, you can touch it when powered because of low temperature and voltage.

I insulate it with a thick fabric only.

What makes this carbon fiber tape resistant? Is it different than other carbon fiber fabrics I can find? The one I tried from the local shop barely generated heat.

I was thinking about making some glove liners and using the removable liner in my riding jacket for this project. But I'd like to know if I connect the gloves at the sleeves of the jacket and have power coming into the bottom of the jacket from the motorcycle if it would work. Or should I have a separate power source for the gloves? And lastly, is the 12 volt power for the bike to much power?

Shenzhen (author)  paul.barber.904759 months ago

Yes, the 12 volt power supply is very convenient for gloves. Separate connection is not required. Connect gloves to sleeves. I think that will be enough 10 watts for each glove, it is not much of power for a bike battery.

Shenzhen Hi, tell me what you used to do the tire warmer to motorcycle tires, carbon fiber, the same material or something else? I need 80 degrees http://www.risingsuncycles.com/images/tirewarmers/TwarmFrnt.jpg

Shenzhen (author)  adam.walicht10 months ago

Dear Adam,

Yes, the same.

Carbon tape better than other heaters if needed flexibility, resistance to repeated bending, uniform heating of a large area. So it's also used in a good quality steer weel heated covers.

Thank you for a fresh idea. We offer you a discount of 20% for you first order on www.carbonheater.us

Do you have a special circuit or recommendation for charging the battery pack?
Shenzhen (author)  elubbers10 months ago

Wow this is great!!

How much power will I need to keep water from freezing in a hose? the fabric dimensions would be 88.9cm x 35mm. I want the battery to be as light as possible also

Shenzhen (author)  leviwilner1 year ago
1. Water temperature?
2. Pipe diameter?
3. Water speed?
4. Air temperature?
5. Air speed?
6. Is it possible to cover carbon tape with some insulation?

1. ~4.4C

2. 6mm inside diameter

3. same as drinking though a straw

4. ~ -7C

5. 0

6. yes there would be insulation over the tape.

Shenzhen (author)  leviwilner1 year ago

Depend on insulation quality and thickness it will be enouph one piece of 90 cm 44 mm carbon tape at 3,7v.

I just received that material (from you?) I ordered online and it came from Russia. I am ready for try things. Would you, please, show the calculations for this example (90cmx44mm @ 3.7v)? Thanks

Shenzhen (author)  macinissa.mezache10 months ago

It's about 8 Ohm/m, so for 90cm it's 7,2 Ohm.

3,7v : 7,2Ohm =~0,5Amper

The temperature depends on current only. I've made a table current/temperature. As you can see it starts from 0,92Amper (39,3 Celsius). I think at 0,5A you'll get less than 30 Celsius. To increase the temperature you should increase the voltage or decrease the tape length.


Great Thanks!
