The Linear Clock,
by Claudio Valdés
How it works: (en castellano abajo)
The main component of this clock, is a linear guide screw motion rail. The moving slider carries forward and backwards a display that shows minutes, seconds (in MM:SS format) and a GPS receiver. A brass pointer or clock hand, is attached to this same component, that points to the fixed "hours display" below. As hours turn and the carriage moves forward, the pointer attached to the carriage interrupts an infrared beam of light that triggers the lightning of the corresponding hour LED display below it.
The source of time for this clock is a GPS unit read by a microcontroller. The hours are set manually by pressing a switch on the side of the clock. Each press of the switch advances the hour’s pointer one hour position at a time. When the 12 hours indicator is reached, the next press of the button will send the carriage back to the position of the 1 hour. This is, by my original design, a 12 hour clock.
Because the value of the actual minutes and seconds is obtained in real-time from the GPS unit, makes it only necessary, regardless of the local time-zone, to set the current “hours” value.
The clock is controlled by two micro processors, one is dedicated to motor control and the other to receive the GPS time and display it.
Como funciona:
El componente principal de este reloj, es un riel de movimiento lineal. Este componente lleva montado un indicador que muestra los minutos y segundos de la hora presente (en formato MM:SS) y un receptor de señal GPS.
Un indicador de bronce o manecilla, que está atornillado a esta misma parte apunta a el indicador fijo de horas debajo. A medida que las horas cambian y el indicador se desplaza hacia adelante, la manecilla interrumpe un haz de luz infrarroja que en consecuencia ilumina el indicador de las horas correspondiente.
La base de tiempo de este reloj es un receptor GPS. La puesta en hora se hace por medio de un pulsador, que avanza, una hora por pulsación el indicador de horas junto con todos sus componentes asociados. Si se llega al indicador de las 12 horas, la subsecuente pulsación iniciará el retorno del indicador de horas y minutos a la posición de la primera hora (1AM o PM). Este es, por mi diseño original, un reloj de 12 horas.
Debido a que el valor actual de los minutos y segundos es obtenido en tiempo real de la unidad GPS, es solo necesario, independiente la ubicación geográfica, ajustar solamente el valor de la hora. Este reloj está controlado por dos microprocesadores, uno dedicado a controlar el motor y el otro ha adquirir el valor de los minutos y segundos.

I wanted to share with you the completion of the Gigachron (Gigantic Chronograph) as I call my last clock design, that I completed today. (picture showing time in military format)
It took me a year between design, chassis fabrication, development of hardware and development of the program.
The vintage vacuum tubes used in the display, are 14x8 cm in size, they were developed as experimental for the Russian army.
I developed the hardware based on a minimal specification written in Russian that came with the display tubes.
The four luminous dots that separate the hours from the minutes and the minute from the seconds are also miniature vacuum tubes, Vacuum Fluorescent Displays(VFD) used as indicators on vintage mainframe computers.
At the front, I added a miniature OLED display, on which I display the selected time-zone, given that the time is read from a GPS chip in GMT (UTC) time, this clock does not require any other time setting.
This tiny displays also shows the hour simultaneously with the main one.
