Build a clock/scoreboard/timer with XL digits
If you ever need a large display to keep the score for games, or a counter for sports events, this is the thing to build. With its four tall (10-cm / 4 inch) 7-segment digits it can be read easily from afar. The project is based on LEDitron modules, i.e. 7-segment displays built from LED filaments as found in modern lamps. And sure, it doubles as a clock!
