Thanks for posting the site for the demo Winston. I got intrigued with
this thing after we replaced the leaf springs in my wife's car. The
nuts were all naturally good sized and all were frozen. The one near
the plastic gas tank couldn't be heated with the torch and had to be
cut with a Sawzall. It was a very awkward procedure. A few days later
I saw the ad for this induction tool, (about 1000.00) with coils, etc.
Seeing the paper clip heated is interesting but it sure isn't a 5/8
shackle nut. It really puts into perspective the power required to do
this sort of thing. Lenny

You will see many YouTube and internet articles
about induction heating.

There is this Extremely Nifty chip called the
IRS2153.

Add two NMOSFETS and a few ancillary components
and you get the basis of a very competent
mini induction heater.

Please keep us in the loop!
