DIY surface mount soldering iron for under $20

Recently had a motherboard go bust: one of the surface mount resistors fell off the board because of incorrect heat redirection from the processor and a DIY water cooler.

  I did manage to find a component identical to the one originally installed on the motherboard. But what I didn't realize, is that its practically impossible to solder such a tiny component (the size of a red ant) to the board, without an SMD rework station , which costs anywhere from $200 - $800 depending on the make and model.

Luckily, I came this tutorial which converts a standard soldering iron into a surface mount soldering iron for under $20. And after completing my own, I was able to get my old server board chugging along again.

A must read for DIY geeks:
