based on his username, [Horatius.Steam], it’s not a surprise that he phone calls this job a “SteamPunk” style binary clock. however we believe utilizing neon glow lamps in this binary clock is more of mid-century contemporary proposition. Either way, the completed look is sure to make it a conversation piece for your home.
He doesn’t provide all that much info on the bulbs themselves. They seem to be neon glow lamps along the lines of a Nixie tubes. It seems like they just requirement mains power (based on the picture annotations for the relay board). The high voltage is changed by that collection of solid specify relays. The controller board includes a DCF radio whose antennae is seen just below the controller. This picks up an atomic clock signal from Frankfurt, Germany. We believe it’s a nice touch that he included a mechanical relay to simulate a ticking sound. That as well as the bulbs themselves can be turned off utilizing the two switches in the base of the clock.
This seems like a great time to direct your interest to an creative handle a Nixie clock.
