That’s 96 hard drives in various states of disassembly. These are usually taken all the way down to individual components for resource recovery. We have recently acquired access to a x-ray fluorescence machine and its pretty amazing to see how many metals are actually in some of the small parts.
Instead of XRF analysis I just needed lots of steel wire and some spacers to put this together. Since the strands are hanging from wire the shiny discs cause moving reflections when something brushes the front of this display. Which will be pretty cool until the wires break and the strand falls on someone’s foot.
