Universal plug polarity damage
We had some more deer damage
that's starting to threaten our Fall garden.
I dug out the trail
camera, didn't have batteries but noticed an external power hole,
found a universal plug, selected the proper voltage and turned it on.
The screen powered up, but then went blank with a slight burning smell.
I'm pretty sure I got the polarity wrong on the plug and burned it
out.....Ouch.....

At one time I was looking for a replacement power brick and I found out (to my amazement) that the polarity of barrel plugs is not standardized.
And to make matters worse, few power supplies or devices have a polarity symbol.
Another good reason to keep a multimeter around!
