Analogic clock for french or english box for example (other cycles can be made).
The display part can be a computer screen or a digital tv set (with standard VGA input). So the size is variable from 15 " to 42 " or more.
The generator is build with a FPGA programmed to generate VGA timings and to calculate drawings and texts along with clock timers Some jumpers are used to select vga standard, 2/1 minutes or 3/1 minutes cycles for activity/pause. Other modifications can be imagined. The first version (pcb in box) is operating.
Commercial offers are welcome.
