Nixie-clock using neon lamps as logic elements (2007)
Summary
A detailed description of an early home-built nixie clock that uses neon lamps as driving logic instead of transistors or ICs. The article covers the motivation, historical source (Dance book), hardware setup (ring counters, LDR-based readout, light attenuators), issues with modern neon lamps, burn-in, and lessons learned, along with references and an epilogue. It's a rich historical-hobby electronics piece with practical notes for enthusiasts.
