Kind of off topic, but: I've been trying to shred iphones and macbooks for a while now for my art. (Much like in "will it blend") I intend to work with the shredded metal/dust as a pigment. Does anyone have any pointers how to actually shred these devices?
Maybe you could shred into small chunks first and then use a ball mill with heavy and hard media. Would be very time consuming and expensive and the result would be toxic, of course.
