Step 1: To Do Such Heated Insoles You Need!!!

In today’s video I am going to share a brilliant idea about how to make a DIY heated insoles. With the help of the electric heated insoles you will be able to heat any shoes. You can quickly catch cold, when sitting at the computer desk or if you have cold floors at home because excessively cold feet cause catching a cold. But if you make such DIY heated insoles, it won’t be easy get sick.

Step 2: It’s Very Simple and Easy to Make Such DIY Heated Insoles!

Step 3: You Can Take Then When Setting Off on a Fishing Trip, Having Charged Them With a Screwdriver Battery!

Especially if you take drill ice auger with you)) It’s two in one make holes, take your battery out, connect it to your insoles, get warm and you can fish not worrying to much about getting your feet frozen) In general it’s an awesome idea, I think you will fully check that out) All pretty simple and easy.

Step 4: Don’t Be Lazy to Make a Pair of Such Heated Insoles, It’s Worth It!

Thanks for watching!!!

    Heated insoles are very useful, I have them in my sailplane when on long and/or high altitude flights. For that they have to be powered by a low-voltage battery, mine has 12V. There should also be a pulsing power supply with the duration of the pulse controlled by a solid state switch. All of that you get in Gerbig insoles that they sell mostly to motorcycle riders (that's where I got mine). A version that you can only use at your desk is useless to me.

    totalblank yes you get sick from viruses or bacteria BUT why are you susceptible? The virus/bacteria can be around you & you don't catch cold. The cold feet put extra stress on your immune system & make you more vulnerable to getting sick. So yes cold can cause one to catch cold. BTW I've been a physician for 60 years, there;s a good chance I know what I'm saying.

    Old wives tale dude, sorry. There are studies showing that being cold, having wet hair, etc. does not affect your immune system in any perceivable way.

    Cold feet or cold anything for that matter does not cause you to catch a cold virus that is a myth. Just wanted to point that out otherwise good instructable.

    This. I didn't even get past the first page before coming down here to comment.

    Why bother? Just go down to your local Sporting Goods store and buy a pair of electric socks used by hunters.

    What AWG of nichrome are you using for 12v @ 3A are we talking warm, toasty, or incinerating for that current?

    ha ha ha , good one ! ( warm , toasty or incinerating" heat ) LOL

    36 watts should get nice and toasty. I would start with something thin, if it doesnt give off enough heat you could always put a second element in parallel.

    Watch the video. 4mm wire.

    4mm is what? 6awg? That cant be comfortable to walk on.

    ChrisB13, it's 26 awg. I looked it up. Its size would be like industrial electrical cable if it were 6 awg.

    Downvote.

    How much wire? How do you control the temp from not accidentally burning up? What voltage?! Drill batteries vary, so does everything else? This instructable is just a disaster waiting to happen.

    Ohm's law and basic thermal insulation computations.

    When you buy the wire, you get its resistance expressed in ohms per meter. You should know your power supply's output voltage. (I'd expect it to drop insignificantly on the wire, if it's a power source meant for more powerful devices, such as an electric drill or screw driver.)

    Given the material of your soles, you should know its thermal conductivity. From that, plus one sole's area, you can compute what power is lost through it for a specific temperature difference between its two sides. (Of course, there will be the sole of the shoe on the other side too, so you need to take that into consideration too - but it's basically the same type of math.)

    You now just need to match the wire's length with the desired temperature difference.

    There might be differences among countries, and I suppose school has changed significantly since I went through it, but this was basic high school physics some 25 years ago.

    Or you can just go very basic and do a few very simple experiments - put tension onto the wire, and see at what length you get a reasonable temperature.

    Agreed. Disaster. This wire is used for cutting styrofoam so if a person has the wrong power supply, they will brn themselves pretty well. There are some folks out there lacking common sense and this Ins. doesn't take that into account. A materials schedule would have hurt either.

    Hi,

    What is the fact only the Amperage can burn; but with the strike voltage - without big voltage there is no chance to burn anything includes the skin of people.

    Under 48 and under 6 years old 24V there is nothing dangerous; because they won't licking those cables, I think.

    5V with 1A means 5W - touching with the skin is not a danger you may avoid at.

    If this heating cable is sharp you can make upper cover using by the same material what applied at the bottom.

    So nothing special.

    Basically, I think this is a good idea but it should have to think better before apply on the grandma's feet. :)

    BR,

    Attila

    It's all explained in the video.
