We’ve marvelled at the work of Paul Parry (aka Bad Dog Designs) before in these pages; here’s one of his latest builds. Paul has got his hands on some Cold War-era military field telephones, and, of course, has turned them into Nixie tube clocks.
Both telephones are housed in bakelite enclosures; the lighter-coloured one (shown here) is a Russian TA-57 telephone dating from 1968–1975; the darker one is a Polish TAP-67 dating from somewhere between 1968 and 1974.
Both phones feature programmable RGB LED back-lighting to show off the Nixies in their best light, four Z570M Nixie tubes, and tell the time accurate to plus/minus one minute per year.
