Home made heated insoles.

[TLPower]

Following hot on the heels (see what I did there) of my wonderful challenge of a gear position indicator, I now challenge the skilled amongst us to make heated clothing.

As before, my input will be just finding a vague link to something that I would like, but I'm unable to make due to lack of skill, knowledge and patience.

Gentlemen plug in your soldering irons.

I reckon mjc could adapt his heated mirror technique.

Wire in a controller. My Keis insoles don't have one and they eventually cook your feet!

[bigpie]

My keis heated insoles burned themselves and broke. My heated vest was still working last winter.

Should be a simple job, electrically. Actually keeping the resistance wire in place might be past what I can do. Plus I'm still on with the last idea you had.

If I was doing it I'd look at using PWM to vary the temperature. I've still got one of the insoles that works. I can measure the resistance of it tomorrow.

Sounds like another arduino project to me, bigpie! Doesn't the atmega have 4 pwm outputs?

well, now you mention it...

Take 1 cheapy insole, cut to size (or if you're brave/lazy, use the existing ones)

Go here: http://carbonheater.us/ (or if you'd prefer ebay, http://www.ebay.co.uk/sch/led-2008/m.ht ... pg=&_from= )

And then here: http://www.ebay.co.uk/itm/New-LED-Strip ... 3384a8d1e2

I think you can work out how to combine the three

Keep 'em coming chaps, no pressure but we do have a mission in a couple of weeks.

Bigpie have you found a use for those wonderful connectors yet?

[mjc506]

or, get a BMW and keep your feet on the pillion pegs near the final drive. That should keep them warm

[bigpie]

That stuff is funky, never seen that before. Nice find.

Might have a play with it. Cannot work out how the wiring attaches though.
Suitable controllers are so cheap on ebay, it isn't worth DIYing.

Looks like a sewing machine would be a good idea, don't think I know anyone that has one.

I'll lend you 1 if it helps  

[bigpie]

I wouldn't know what to do with one. :D keis insoles draw 1.3amp so at 12v they have a resistance of just under 10 ohms.

That stuff is 19ohm per meter.  So half a meter across both insoles, in series should be similar.

[TLPower]

I have access to a sewing machine...

[bigpie]

Know how to use?

[TLPower]

Found a little more info http://www.advrider.com/forums/showthread.php?t=887651 is this the same stuff used ? http://www.ebay.co.uk/itm/Carbon-Fibre- ... 563ef99627

Whilst dog walking this morning I was also contemplating a heat exchanger from the exhaust or from the cooling system.

[TLPower]

How difficult can it be?

[bigpie]

Fairly easy, I already have a controller.

Heated socks might be a better idea. With my heated insoles the top of my feet were still cold winter before last.

[TLPower]

Socks would work. Several other folk mentioned the cold on top of the foot. What did you think of the carbon tape idea? Am I on the right lines?

[TLPower]

http://www.sciencemadness.org/talk/view ... ?tid=28078 I might have to order some...

[bigpie]

Carbon tape is looking to be the way forward. It's almost as cheap as resistance wire. Order some and I'll give help if required. Still need to tweak your voltages.

[TLPower]

Just ordered 3 metres.
