[RE-wrenches] Reliable Cheap Modsine Inverter

[Dan Fink]

We have a nice old Tripp-Lite inverter in the attic somewhere here
that would be a *great* baseline of square wave from which to compare
any sort of "modified" square wave! Oh sorry, they now call it
modified "sine" wave. My bad.

I'm planning on oversizing it substantially, I figure I would start with something at at least 400 w cont rating, just to make sure.  I had an old no name 1500 w inverter on our work truck that we took in on trade, and it actually ran a circular saw.  We tried to burn it out and never did.
