Decades ago, Nixie Tubes were used as indicating devices in many different types of instrumentation, and ultimately replaced by the cheaper – and unattractive -LED display.
Having been obsolete for almost a quarter century, these glowing bottles of ionized gas have attracted another generation who appreciate their beauty and mysterious function.
The display tubes may be decades old, but the clock is GPS accurate. Those who’d rather just fiddle with Nixi Tubes than spend a pile on on a clock (though we all agree it would be well spent), can buy bare tubes here.
