Dirty's heated clothing, heated glove thread

[DirtyGinge]

oops , pic of hoddie in question

The only change I might suggest is to use
iron on fabric on the inside to both cover
and protect the wire.

That will keep any zippers or stuff from s
horting the heating element

[DirtyGinge]

yup, agreed....todays run was just a trial though, quick and easy,  ( getting a dual layer body warmer may be more preferable....

For me, I only use t-shirts under these but even a cotton panel on the inside would be fine....

 ( I need maybe slighty longer, as its been recommended to me to do the lower back also )

This will be worn under a waterproof jacket, to keep the wind directly off it ( which makes so much difference in the cold.....waterproof to keep wind out, jumper to heat, skintight base layer for warmth, last nights honey wine ( honeybeer, for the sake of the aussies) for antifreeze

Nice picture. Glad to see your still into disney movies, stickers and colouring

You chaps are nuts! 

I got an easier idea Ginge, how about buying one of the heated body warmers in Maplin ? and some heated gloves!

I can imagine you flying by on your bike with smoke from your jacket!   

[DirtyGinge]

buying stuff, dya think im made of money ?

So I managed to wire 5 metres of wire into the front of my hoodie, and went with it....there have been some cold misty mornings here so it was great for testing

initial impressions
4.2V ( 1S).....nice if you are indoors in a warehouse ( like mine), but not much cop on the road

make sure you do wire higher up the chest than my V1 hoodie, it does get a bit cold there

so I went 2S 8.2 V,.....my god, its roasting.....I am so happy riding to work finally, the winter is going to be one of glowing ginger buddha belly ........it needs turning down a bit so perfect for me would be 8.2V ( 2S) x 7 metres....

However im going to 12.6(3S) ( as these are the mainstay of my battery pack)...and 10 metres of wire, giving me the same heat but just over a greater area...I Will use plug in gloves, using 30A Andersons , and if not , use a loopback connector on each sleeve end ( just a connector grounded positive to negative, just to complete the circuit if no electric glove present....


What do I think, for a bloody £20....wehayy.........

Need more runtime ...and controlability

Have ordered a PWM controller, 12V in , variable 0-100% out, 0.01% Efficiency.....although ebay said heathrow, shipped from whom say may tai jai warehouse in god knows where, otherwise im going to build my own pwm circuit with pot for "heat volume"control

but for winter riding........priceless................

Ha Ha nice one Ginge mate!

I got a great winter idea, take the car LOL!

[DirtyGinge]

mark, if you take the car, you are going to put on all that chubbyness

So weird how everyone has their own reasons for riding!

I'm complete opposite in the eyes of "Riding for fitness", I ride a little for exercise, but mostly ride for fresh air and the sun when its rarely in unpredictable Melbourne

Considering the amount of 'sitting' I do compared to pedalling, I am very curious of this 'plug in' heater.

What kind of current are you drawing with your 2s setup Ginge? Like how long will it last with your battery packs? Even Spring and Summer is Winter weather here at times......

[o00scorpion00o]

mark, if you take the car, you are going to put on all that chubbyness

Yes Ginge, but if you don't pedal you'll put it on too!

i keep fit dodging rabbits..........takes a lot of effort to steer this prime love machine around the road

[o00scorpion00o]

haha Ginge,

Yeah I hate that on the country roads here, and rats especially this time of year running around through the fields with all the harvesting!

I would hate a rat or rabbit to run head first into the spokes! yuck

[DirtyGinge]

Right, so I rewire Version 2, with another hoodie....and a spanky fresh PWM motor controller courtesy of Ebay

http://www.ebay.co.uk/itm/12V-15A-PWM-DC-Motor-Speed-Control-Regulate-RC-Model-/250882728751?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item3a69c6a32f


This time
wire higher up the front
wire the lower back
switch to 12.6V 3 series lipo ( 3ah)

The resistance reads about 2.6 Ohms, giving me about 5 amps of current pull, for about 60 watts of heat......to give you an idea, 60 watts, even at 8 metres in length, burns my skin...

runnin within the "nice n safe" margins of lipo ( 4.2 to 3.7), I get a runtime at full power of about 25 minutes., you would need pack capacity of 6ah, to deliver 5 and be nice to the batteries...

However, you really cannot run it at full power, its just too hot indoors, so I wire in my nice PWM controller and give it some...

I get 0-100 percent full adjustable control via a "volume knob" pot......sweeeet

Now I just need to wait for a cold day ...

[DirtyGinge]

I'M WARM, I'm WARM

Run today at outside temp of 8 degrees with wind......

Run at about 40-50%, run time of 75 minutes, and for once my first winter cycle isn't completed with me just miserable......I'm just nice n toasty

Anyone have an easy to build PWM controller for 6 amps ?, or how about a cheap supply of 60V to 12V DC-DC converters for 6 amps....

You are all going to want some of this action ;

[Bikemad]

Ginge, good to hear you have not been electrocuted yet, and hopefully you're not suffering from minor burns either.

Run at about 40-50%

I'm curious as to how you've wired the potentiometer to actually control the output of the PWM motor controller, are you using a servo tester powered from a single cell?
I'm guessing the controller doesn't have reverse, or it would be off (cold) in the mid position, and vary up to full current (hot) in either direction.

how about a cheap supply of 60V to 12V DC-DC converters for 6 amps....

You might want to check out this post on ES, it could be an alternative use for a switching type power supply, which are commonly used to supply low voltage power to laptops, printers and LCD monitors etc.
