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

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

No battery was shown, so that's not conclusive.

I'd guess that he patched in 12V from a vehicle and used the charger's
regulator to drop it to 9V, with charge control.

What's that Lassie? You say that Stormin Mormon fell down the old
rec.crafts.metalworking mine and will die if we don't mount a rescue

No AC power cord shown either.
