Might it be possible to fabricate a simple hot air re-work station

Here's the item in question (which I recieved as a gift and have no
use for).
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=41592

Thinking that it's pretty much a hot air station already, would it be
feasable to:

Add Thermocouple, adjustable diaghpram pump, and Pic controller to
create a semi usable Hot Air re-work station?

Mostly, I'm just looking to de-soldier larger SMD chips, and also can
you have too many intersting projects?? :)

If the answer is "yes, maybe" and since I've never held a hot air
soldiering iron:

How accurate must the output air temp be?

Exactly what temp range should I anticipate?

How much air flow?

Any ideas (other than the obvious "go buy a real one")

And no, my income does not depend on this device, its strictly a
method of killing time and money.. :)

The temp and airflow would enable you to reflow the paste flow to build widgets and to soften large areas and non destructively remove as well! lloks like a winner! Not clear on one thing.. does it make itown air flow or do yu need a tank or compressed air supply. please have orogianl poster confirm whter it blows own air!


Looks like it needs to be connected to an air system. I guess they assume that a real man's garage will contain the biggest honking compressor the neighborhood has seen. Red, at least a 5ft tall tank, and loud.
