iPod Shuffle 3G won't charge, or do anything.

My iPod Shuffle 3G won't charge, connect to my Mac or give me any sign that it's working. I used it about two weeks ago and it was working but now it is not responding to any thin I do. When I plug it in to my computer it never shows up on my iTunes and when it's plugged in all it does is get hot after a few minutes so I unplug it because I know that's not good. I tried to see if it would show up under Disk Utilities but no luck. I am thinking that there is no hope for this $80 paper weight but I just want to know that I have done all that I can. If someone knows how I can fix it then please tell me other wise I am done wasting my time trying to fix it. It is also out of warranty by a month so I can't take it in to get fixed by Apple.
