Homebrew PCBs

I don't know if any other members have heard of this, but there is a 
new cordless soldering pencil that has been created. Its called the 
Cold Heat because it reaches 800 degrees F on contact with metal. It 
only runs on two AA batteries; it isnt recommended on sensitive 
components that the quick temperature increase may harm. And 
apparently, a few sites have recommended this tool for most jobs. Its 
at www.ColdHeatTools.com. Of course, this isnt a heavy duty deal, 
just a nice little gadget to go with the chest.
