ThePhoton’s Nixie clock that we have followed over the last few weeks is done done done, nice work! – “After nearly three months since the beginning of the project the clock is complete. It uses four GNP-17A tubes for the main hours and minutes display, and two IN-16 tubes for the seconds. The case is made from African Padauk with much sanding, cleaning, and coated with Polyurethane varnish all over. After a few months it will be time to start on Nixie-2.” – Link.
