I live in woodbridge and own a soldering iron. I know how to solder, if you know what needs to be solder'd where, i'd be happy to help.

You'd hafta supply your own solder though. couple bucks from radioshack

If you want to DIY, the easiest, most sure fire way is to use Chip Quik and a cheap solder iron. The third thing you would need would be solder.

If you can take a decent picture of it, maybe with a quarter placed beside the chip, I will tell you if I would do it for beer.

I need to buy the chip yet, but this is what is needed (very small tolerances):

I have a soldering iron and can solder, just not this tiny...

You should be able to see the write up, I added a pic (picasa sucks for embedding images).

Post to imgnook.
It's free and will generate the img code for you.

I googled the chip name and looked at the data sheet. Based on that pin spacing, I'm not sure if I would even bother putting it under the microscope.

If you go just trying to heat the thing up with a soldering iron, you can rip up the pads and surrounding traces. I would do it, if you brought it to me, for craft / Belgian beer totaling between $10 and $20.

Do you do it while I wait or two trips? Either way, I am up for it. I assume I bring the chip with as well...

It should take a matter of minutes. I'm located directly on the beltway for your convenience.

That's like the smallest picture ever but I get the idea

I can send the full rez one. Not sure if Picasa is shrinking it or the board....

Ordered from a place in MD. Once I have it in my grubby hands I'll get with you for a link up time.

Preferred beer or leave it up to me (I'm a beer snob, but lean to Stouts).

I like most stouts, so that would be a fine choice. Most anything except heavy wheats or crap that they try to blend fruit in with.

I'm around a lot but travel some. Just let me know when you have it and we will find a good time. I might be gone next Mon-Wed for example. I hope you picked the right chip to replace!
