Trouble getting started with CPU Hand Warmer...

[SlacinAce]

Just to show off in school, and keep about 5% of my body from freezing this winter, I want to make a cpu hand warmer, but I'm just having trouble getting started...

 

So I currently have

Some unknown model of an AMD Athlon from 1999

A 5V DC 2000mA portable charger

USB cable with only exposed power cables (ground and positive)

 

So my 1st problem, I just want to know what model it is, This is the only picture I can find that is near similar, the only difference is the 2nd to last row of numbers on the bottom of the center chip thing. I'll just go with AMD Athlon 1200 until I find out more

 

My 2nd problem, is the multi-meter, but the only kind I have is to read currents, it can't push any current through the processor to test it. I used the resistance testing thing and found a bunch of pins with no resistance, but when I touch the wires to it, no heat is produced, at all. I'm just confused

 

3rd problem, is just which pins to connect the usb to, I wish someone has already done this with this processor, but no luck finding him or her

 

Any help is appreciated, thanks!

I found the data sheet, someone convert this into understandibly English for my tech virgin mind....

What I mean is what am I supposed to look for, I have no idea where to start, I just want a hand warmer

I don't think this project is within your skill range just yet. Grab yourself a Samsung Note 7 and use that to warm yourself.

It probably isn't in my skill range, but nothing else to do with this processor, so I can fry it no problem

 

Thanks for the comment!

Thanks you, but this is the video that inspired me... I have an old pc upstairs with a pentium 4 in it... Great and easy because of all the online sources but, I might still need that pc as it is my "backup".

 

But since I have this AMD cpu just sitting around, I know it is still operational but the only use for me now is to learn to make a hand warmer

Thanks for the comment!

Okay, I finished it! It warm steadily and hold a stable and comfortable warmth!

 

Just for people if you have similar problems,

I used the multimeter to test resistance, and I chose 2 pins with resistance, but about half resistance, just so it will warm slowly and not get too hot, but if you want the heat to get more intense, choose pins with slightly more resistance, and same concept with less heat, less resistance. If you're into searing pain and little PCB frags, choose pins with total resistance. (don't actually, I am not responsible for any injury)

 

I still have a lot to learn, I'm not even sure if what I said works, but it works in my conditions. Thanks to all who helped though!
