I managed to get 15 of the “slugs” from sparkfun.com
I heated one up till it became brittle and cracked apart
Turns out they are not just a piece of copper!
there is gold and silicon in them :)
looked more impressive under my microscope at 3x you could see there was actual circuitry on the silicon.
little gold wires connecting the pins to the silicon barely visible in the scan
Filed down the chip then used acetone to make the plastic weak so i could chip it away easy with an exacto knife
now the real question.. what is the chip really?
