I don't, sprechen sie deutsch so I don't know what it all said but on that German Flashaholic site Vinz also had pictures of an XML build with a copper "hull" or shell for the drop-in. Kind of a game changer for me. The work looks impressive, I can't wait to hear or read more. (I only speak Spanish and English)
That was basically the first prototype. They are usually made out of aluminium because copper has hardly any benefits as long as you mount the led on a copper pcb.
