Neon Ring Counter

Neon Bulb clock made out of IN-3 neon bulbs arranged in 8 ring circuits and IN-12A nixie tubes to display the time. The clock is powered from 240v AC @ 50HZ. The transformer produces 125v AC, which is rectified to aprox 170V DC. The 50HZ signal is divided by the 10 bulbs of the first ring circuit and outputs 5HZ. This is further divided down by each ring circuit to produce seconds, minutes, tens of minutes, hours and tens of hours. The last 4 ring circuits are connected to the nixie tubes to display the time. The video shows the clock being set to 2 minutes to midnight to show the clock rolling over at midnight. The time is being set by the application of a magnet which is tripping two read switches inside the perspex case.
