Made from vintage Nixie Tubes (old-school electronic displays) reclaimed after sitting for 30-60 years in Russian warehouses, the exquisite K7 Klok Kit will win over DIYers and design geeks alike. Industrial designer Mike Mayberry custom fabricates the limited edition, aircraft aluminum housing that he sells along with the tubes as a kit for home assembly. The beauty of the ten layered electrodes glowing orange with overlapping dimension can only be appreciated when it's right in front of you. See more info and a link to a video here.
The K7 starts at $129 and tops out at $295 for the largest size tubes and can be ordered through Klok Modernâ€”supplies are limited, so act quickly!. A few more parts are required, which Mayberry provides links for here.
