I found this little gadget in one of my spare rooms in a bunch of old electronics and cords. I didn't make it and I don't know who could have. I've tried identifying it and nothing.

I put a little power to it and it makes a whinnying sound. I will take pics of it from outside then the board. Someone went to great lengths to close it up used a thick black composite maybe jb weld? I had to shave down and cut into the end in order to open it.

Often, components in power supplies will vibrate causing an audible hum. Sometimes, this is avoided by covering them with a thick epoxy or other potting compound.

If it is a power supply, great care should be taken when opening it.
