Here is the text:
I needed a portable 9 volt D.C. power supply for an
experiment. I happened to have a
broken power tool battery charger.
Rather than repair it, I removed its transformer and drilled
a couple holes
in the top to receive a pair of banana jacks. I was able to
conduct my experiment
without having to lug a lab supply and arrange for an A.C.
outlet in the field.

It worked a treat!

--WinstonHere is the question: Since you don't have 120 VAC
in the field. Where did the electricity come from? Empty
box, with no line cord, and no transformer? That's seriously
brilliant.... not!

I avoided lugging a lab supply and extension cord
into the field with this no-cost jig.

I'm guessing the power comes from the battery inserted into the gutted
charger, the charger is used for its contacts to the battery.
