 These oscilloscope clocks display an analog face for ten seconds and then a digital face for ten seconds. This helps to reduce the "burn-in" that otherwise will inevitably occur on crts displaying the same image for too long. Many of the parts are recycled from used electronics, which makes them kind of "green". The base and shroud are homemade from plexiglass. These scope clocks have a "shifter" that will move the display on the screen slightly every 6 seconds. Also, the display alternates every ten seconds between analog and digital. This helps to greatly reduce the burn in that can result from the display staying in the same spot continuously. The Nixie clocks are "faders", which means when the numbers are changing, the number that's going is dimmed while the number that's coming is brightened. This produces a "morphing" effect that kind of makes them appear to melt into the next one. The oscilloscope clocks are user programmable with preset sleep / wake mode, which will turn the display on and off at preset times automatically, while still keeping time, thus conserving the crt usage and extending its lifespan. The Nixie clocks also have this feature, as well as a calendar with leap years until 2100 and a rudimentary alarm. Everything is homemade and built by hand, not a commercial product.
  All of the cases for these clocks are homemade. The base is a 1/4" plexiglass and the shroud is 1/8" plexiglass thermoformed. The shroud just sits loose on top of the base; it is not attached. Obviously, user descretion is advised.
  International buyers please note: The newly redesigned board can be set for 240VAC as well as for 120VAC (U.S. standard) electric service. The firmware will automatically set for 50HZ or 60HZ on startup.
