Hey all 🙂
I was thinking about this for about a week now...
I've searched on the net and found some places that sell heated clothing.... but they dang expensive!! 🙁
how would you build a heated clothing system?
you can't simply run strips of wires down the length of your clothing... it would burn the material no?
I think this would be a cool diy project... dunno bout you guys? 🙂
If I wanted to do this in a simple way... with a battery and a variable resistor as heat control... what else do you think would be needed? We can throw our ideas together and come up with something generic we could all make 😀 hehe
anywho, thanks for the help 🙂

No. They sold electric blankets which worked well enough for many years. I believe that they finally took them off the market for safety reasons, but the fact that could sell them for so long before the safety issue arose shows that the percentage of times they catch fire was very low. If the percentage was high, they never would have passed the Underwriters Lab tests in the first place-or they would have been off the market in the first week.

How about a convenient way to transport a car battery around with you while you wear these clothes? Heating uses up a lot of electrical "juice". Just ask anyone who has an electrical heating system in their house. 😉 😉
Truth to tell, Multiplexor, I can't really blame you for thinking about this, though. Temperature last night:
Connecticut: 6 degrees F
Juneau, Alaska: 30 degrees F
It's not supposed to work this way!! Alaska is supposed to be colder than anyplace else.
Who do I see to complain about this? 😕 😕

Power supply of the Clothes heater
Best is if your bodymovements can be linked
to a generator that can store/power the heat.
Maybe you can have a genrator built into your shoes?
I have seen some portable bodymounted computer system
work that way.
But microchips needs only a fraction of the energy
that a heating system would need.
Solar cells is not to be trusted
in the cold period of the year.
If you walk very fast (run), you might br able
to use some wind catching energy generator.
/halo - wants not to carry Car Batteries around ...

hehe i'm looking for anything... where it could warm me up for like 30 minutes even... this way next time i go out and when i finally start getting really cold, just flip a switch and warm up a bit... then flip it off 😉
batteries are not an issue when i get cold... hehehe 😀
you think supercapacitors could be used in this case? to ease the load on batteries? like the batteries turn on and off every 5 seconds.... load the caps and turn off...
just throwing ideas out there... 😀

Re: Re: Diy body heating system... it's cold out!
If they are no longer allowed in the US, maybe it is rather the
slight risk of electrocution that is the reason? I have never
heard of electric blankets catching fire, and they are still sold
here. Further, here in Sweden we have had electric heating
for car seats for as long as I can remember. Originally it was
in the form of separate things (not sure what to call them in
english) that you put on the seat and connected to the cigarette
lighter jack, but since long ago practically all new cars sold in
Sweden had built in seat heating. I have never heard of any fires
caused by these things. Actually, when I was very young we
had a Volkswagen Beetle, which had 6V electric system, and
my father had a heater he used on his seat in winter. When we
later bought a Volvo, he continued to use the same heater,
despite the Volvo using 12V and later I used it in my first car,
which also had 12V system. It heated up very quickly, but
catching fire? No, never! 🙂

Re: Electrical heated clothes exists
yeah, i found some of these sites also 🙂
i think www.widder.com is another...
it's like everyone is making them for bikers... can't find anything for regular people who don't "ride".... those who go skiing and need the little bit of extra heat... 😀

Re: Re: Electrical heated clothes exists
We use a lot of them in Sweden.
We call them "snö-skoters" (snow-skoter).
What are they called in English?
-----------------------------------------------
this is a swedish magasin for "Skoter".
http://www.skoter.se/scripts/startsida.php
There are also a lot of people here in north of Sweden
competing in Racing with these machines.
There are machines with strong engines that:
Gör 0 till 100 km/t på 2.5 sekunder…
Does 0 to 100km/h in 2.5 secs (100km/h= 62.5 miles/hour)
halo - has no skoter
Yes, those gloves was for "Snow Bikes".multiplexor said:

Looks like I was wrong about the electric blankets not being sold in the USA. This recall link shows that they are still being sold, or were in 1991.
http://www.cpsc.gov/cpscpub/prerel/prhtml02/02003.html
I knew people who had them and found them very satisfactory, by the way.
Checked out some British sites and they seem to say that the big problem is when the blankets get old.

Re: Re: Electrical heated clothes exists
You don't suppose that might be becase motorcycles have smaller versions of car batteries, do you? 🙂
Kelticwizard stands corrected and amends his original statement. For heated clothes, you don't need a convenient method for carrying a car battery around with you. You only need a convenient method for carrying a motorcycle battery around with you.
LOL, it this keeps up, people might start doing it!!
Halo-we call them snowmobiles on this side of the Atlantic.
PS: You can substitute a snowmobile or snow-skoter battery for the motorcycle battery.

Re: Re: Re: Electrical heated clothes exists
the simple reason for using a car battery is because it can deliver enough amperage correct?
so simply put you would need somethnig that can deliver around 12 volts...
Couldn't it be done on 6 volts?
😀

If I remember correctly, the most recent concerns regarding electric blankets involved the effects of low frequency EM fields. The fear was that even though the current through the blanket is fairly low, the field strength your body experiences can be quite high because the wires are essentially right at your skin.
I think modern electric blankets are wired such that the EM fields cancel (a twisted-pair type arrangement).
Anyway, this would not be a concern in your DIY battery-powered (DC) underwear.

Question though, fo the electricity experts 😀
If I simply wanted to have a heated wire... how would i go about doing this?
I take a small strand of wire and apply + and - to each end of it??
or should i have something in between?
how can i find out how much voltage i need to heat a certain thickness wire?
🙂

Anothe method
I am a newbie here, and this is my first post, but check out
http://www.hedfoundation.org/liquid_cooled.htm
If its good enough for nasa!!! only use it in reverse.
I believe the Maclaren F1 team use a similar system for the pit crew for when they race at circuits like sepang in malaysia.
they have small tubes that un through the clothig, through which is pumped a cooled liquid.
Why not take this and do it in reverse, pumping a heated liquid around the suit. It would keep all the technology in a simple pack, or belt pack. and cut down the risk of electrocution etc.
Just another thougt to band around!!!!

Body heating
Hello guys,
You could also check out North Face clothing. They have a kind of textile with in woven electrical heating wires. The accupack consists of a LiIon battery (I think two batteries is an option). Furthermore the jacket offers two settings. I think the jacket is called MET-something.
Cheers,
Jarno.
