Version vom 17. Februar 2014, 16:12 Uhr

Dieses Script wird einmal in der Minute gestartet und prüft das Ring-Signal der seriellen Schnittstelle. Wenn unsere Außenbeleuchtung eingeschaltet wird, gibt es dies im IRC bekannt. Ebenso gibt es das Ausschalten bekannt.

Der Schriftzug besteht aus einer blauen LED-Lichterkette, die von einer gelochten Kunststoffkonstruktion in Form gehalten wird. Das Netzteil liefert 24V Wechselspannung, welche jedoch im Stecker der Lichterkette (Zusätzlicher Stecker zwischen Netzteil und Zuleitung der Lichterkette) teilweise gleichgerichtet wird. Die oben dargestellte Schaltung halbiert und glättet die Spannung, so dass diese direkt am Seriellen Anschluss eines PCs ausgewertet werden kann.
