Frequenzanzeige Weschelrichter

Beitragvon bambam » 25.04.2010, 14:33

Hallo,

ich habe mal den Wechselrichter aufebaut. Funkioniert super. Nur an Stelle der Leuchtdioden würde ich gerne die Frequenz über eine Anzeige (7-Segment o.ä.) darstellen. Gibt es hierfür eine einfache Lösung oder schon was fertiges zum Kaufen?

Vorab besten Dank!!!

Ist blos etwas groß...
Vlt. könnte man mit einem Tiefpass etc. sowas einfacher machen.

Du kannst einen Frequenzzähler mit einem AVR machen. Da gibts Anleitungen und Software genug im I-Net. Frequenzzähler braucht man ohnedies im Elektroniklabor :idea: Wäre ein schönes Bastelprojekt :wink:

Wenn du 230V Wechselrichter überwachen möchtest:
Da gibts so "Energiemonitore" zum in die Steckdose stecken. Die zeigen Blind- Schein- und Wirkleistung, Spannung, Strom, und Frequenz. Das wär in dem Fall vielleicht am praktischten. :wink:

Er meinte den von der Elektronikerseite der hat einen Multivibrator als Takt oder bestenfalls einen 555er.
Quarz gegen Quarz ist klar dass man da nicht weiß wer wen "misst". WmmM :wink:
