DIY Heating Pad

[@jacosalva5852]

Hi Shaun!! Can you share us a list of components you used here? Thanx!

[@suzanneabad3539]

A suggestion for your next endeavor... For a smaller one, use one of those potholder looms (usually found in kids crafts) for laying out your wire. Your wires will be evenly spaced and you just take the tape and lay it down on the wire (as opposed to the other way around) after most of it is stuck to the wire, gently detach the wire from the loom and finish attaching the rest of the tape.

I found your video of interest as I have been trying to find out how heating pads are made. I am interested in making a far infrared heating pad for the feet as I have neuropathy and my extensive research indicates that far infrared heating pads are the only means for palliative relief of symptoms. Can you help me out with making a far infrared heating pad similar to the pad shown on your video? From emissivity tables I find that frosted glass, cardboard, ceramic and wood have emissivity in the far infrared region at a temperature of 40C. I would appreciate very much your help towards putting together a heating pad using the materials mentioned or any other that you know will emit far infrared radiation at 40C. Thanking you very much in the hope you will be able to help me.

Rather than duct tape I'd try using the interfacing fabric used in sewing/dressmaking. It's soft, strong and self adhesive (on one side) when a hot iron is applied to it.

[@thebeastfromthesoutheast7765]

What if you got a wooden board the size of the sheet and make the pattern you want with nails and coil the wire around the circuit of nails then heat the whole wire up until it stays in its form then place on to the sheet. Just wondering if that would work or not?

[@ShaunDobbie]

That would work brilliantly.

[@kevinapa-an2308]

This is good for pets, specifically cats when they are sick their temperature tends to go down and need some kind of heating pads like this. 💯

[@Zodliness]

I repurposed a couple of heating pads out of an old back massager, Keeps my feet nice 'n' warm! The pads maintain a steady temperature once they get going, needing about 800ma each, powered from a 12vdc 2amp mains adapter. I also added a couple of small pressure sensors under the flexible heating pads, so they would only turn on when your feet are resting on the pads.

[@Asyss_Complex]

May I know what kind of pressure sensors you used?

[@Zodliness]

@@Asyss_Complex Based on an old Tandy product, I fashioned two strips of sanded spring steel measuring tape, separated by a number of small strips of double sided tape spaced at intervals along the steel, smaller tape gaps varied the pressure required to make connection between the steel strips. An alternative is two sheets of foil separated by a thin foam sheet perforated with varying sized holes, also to adjust sensitivity. Combine the pressure pad with the heating element to create a one piece auto switching heat pad..... Hope this helps...

[@Asyss_Complex]

Zurkster Ok, I initially thought about a sophisticated sensor that you bought from somewhere. The idea is very clever though. Thanks for answering!

[@Zodliness]

@@Asyss_Complex No problem. I specialise in making out-of-the-box gadgets/inventions using repurposed materials, cheaper and just as effective if well made.

[@sundersquare]

What were the batteries you are trying to keep from getting too cold used for can i ask. what kind of battery are they too, i didn't catch it? thanks

[@juliaerenburg2782]

Thanks for posting this I love soldering, replacing regular batteries with 18650, I bought a "lot" of 6 and 14 laptop batteries, I also make wall plug things like led lights portable I have a set of 4 non flexible sound reactive led strips, powered by 12 volts, so I made a double battery (3 in series x 2 in parallel) using 18650s and stuck them onto all the fields on my fat Tire bike :) that has a big Sony boombox on a floating backrack so they light up to the music. They last a long time and I just charge them straight from 12v DC adaptor. I also have a RGB IC tube led light strip (silicone coated) on the sides, it displays many colours at the same time, on the sides of the frame and a blacklight strip under the frame :) Call it a Porto - Party :) Anyway, I'm working on a concept of heating pads under the hand grips, so two small rectangles rolled, and one custom sized pad on the seat (fat bikes love winter:))) I was wondering can I use a coated wire? I also have a non coated beading wire, could I use that ? And I have vinyl sticker rolls ( to make car decals on my Cricut machine), they seem to be pretty much the same as your carbon tape, and it helps that there stretchy and sticky and withstand heat (they wrap cars with them). Is it ok to make them perforated in case I wanna make a heated vest? Cause non breathable large pad would make the back sweat which is not good in the cold. I appreciate any replies! Stay awesome

[@ronaldhemmings2476]

The info on the wire - wire model number ,size , amount, where was it purchased.

[@chimera91977]

this is exactly what I was looking for... I work construction and want a way to commute from my car to jobsite on my scooter... problem I am facing is I hate folding and stuffing the scooter in my car and I know with cold morning Temps that my battery will be cold from driving with it on the bike carrier. Was wondering about a heating blanket to could wrap the deck of my scooter with in the mornings to "preheat" the battery with... looking at industrial heater blankets, even the cheapest ones are around $90... I thought surely a piece of resistance wire to make my own would be much more cost effective.

[@incoldblooderz]

can i use this for diving?

[@yalgret]

Duct tape is really flammable. Light a small price with a lighter and see how good of a fire starter it is.

[@ShaunDobbie]

You're right, this would be dangerous on anything operating at higher power.

[@ambujbansal7676]

Hi i want to make a defogger for mirror will it work there also?

[@pinkypete6079]

Could I use this for a seedling heat mat?

[@ShaunDobbie]

Yes

[@dmon553]

Can you use copper for this device?

[@jerrymaxey4664]

No copper is a good conducter

[@sagru0b]

What is the material of this wire and where can I buy it ?

[@ronnyb4277]

Nichrome

[@angelaeuth2462]

Can you explain how to make the battery thing to straighten the wire

[@bittertruth6575]

Hi Shaun. This is an awesome idea mate. Do you think its possible to make one to run off 240v? I was thinking of making one to help my seedlings grow by just using electrical 1.5mm2 twin core + earth wire (for domestic lighting circuits). Would it work or is it dangerous?

[@ShaunDobbie]

It would be very dangerous in this case, please use a soil warming cable instead.

[@bittertruth6575]

@@ShaunDobbie Got you. Thanks for the reply Shaun.

[@anasmashhouer3185]

How much heat it give

[@DIYTools457]

Hi, can you use this sistem to heat the water ?

[@Kuchenwurst]

Theoretically yes, but it would be quite inefficient and slow, as water is notoriously hard to heat. It would be enough to keep it from freezing, though, if that's what you're after.

[@Dexetre]

Do you think that I can use a Nichrome Flat Heater Wire for a 200*C Heating Element (10M Length 0.15/2mm Thickness)? What power source would u recommend? (I want to make a automatic lane fabrication for 1 biscuit for my degree project :D )

[@ShaunDobbie]

You could but you'd need a totally heat resistant material. The stuff I used would melt. Use ohms law to find the current and size your power supply from there.

[@michaelagda1577]

what kind of wire is that? is it copper wire?

[@ShaunDobbie]

It is thin nichrome

[@vladimirvansa6044]

Hello. What is that foil?

[@ShaunDobbie]

What foil?

[@vladimirvansa6044]

That black thing where you put wire.

[@ShaunDobbie]

Vladimír Vansa It's not foil.

[@vladimirvansa6044]

So. What is it?

[@ShaunDobbie]

Pastry

[@kenbhatti3621]

What is the use of this without temperature regulation. Very unsafe

[@jcreedy20]

Wrong, If you set the voltage correctly and use it in the proper environment as explained in the video (Use of Ohm's law), it is not unsafe at all. Heated jackets, gloves, motorcycle hand grips etc that you can buy commercially are all set correctly, they are not unsafe, nor do they have temperature regulation in a lot of the more basic heated jacket products etc. If you had said, "It would be very unsafe if a complete amateur attempted this without taking the proper precautions", then I would agree with you. Simply saying Very unsafe without temperature regulation is too broad a statement.

[@ronnyb4277]

SOS!! Supply: 5v 1A and 32G Nichrome, what length do I cut for the element?

[@ShaunDobbie]

I am not sure but on 5v with such thin nichrome you will not get very much heat if you make it as long as mine. You would have to put several strands in parallel if you want a larger element. There may be calculators online.

[@rohan224519]

I calculated to about 14cm for a 5W element...obviously that's too short for any useful heat distribution. What happens if I - (1) Use say 5x that length without changing any other parameters? (2) Twist the wires and make something like a double or triple stranded configuration?

[@rohan224519]

PS I need to reach a temperature of around 40C only, from room temp of 20C.

[@joshhagen4182]

Fucking duct tape... genius. I think I'm going to try sticking it to the tape and laying silicone over the backside thank you so much
