Reuse old TFTs as huge clock
What is it The clock is driving three VGA monitors, each of them displaying two digits from the current time. The clock is DCF77 synchronized (this is a time broadcasting station in Germany), so it always gets the right time.
Hardware The clock consists of two major modules: three DuinoMite basic boards and a DCF77 receiver by Conrad Electronics (a huge electronics retailer in Germany).
The three boards are connected to each other using their internal COM ports, two are just displayers and one is decoding the time from the received signal.
