@jwinnie microchips? I'd like to see someone build one in their garage.
But it hasn't happened so far. Same goes for all PC hardware.
Old computers are possible, but good luck doing encryption on those chips.
or try making a medical implant.
or an MRI scanner. idk how you'll even build the tools that will let you build it.
