Very nice! Hope it develops into full project with source code.  Attention to mechanical detail was excellent.

ja das hab ich ja dann auch gefunden. Siehe mein Update das eigentliche Problem waren wohl die default Flash Einstellungen für den ESP, die beim ersten mal flashen zwar funktionieren aber nicht wenn schon mal was anderes drauf geschrieben war, da kamen dann sogar Runtim Errors also nicht mit der timelib.h zu tun So erkläre ich mir das zumindest. Seither läuft das Ding 24/7 ohne Probleme.

Thank you all for the motivating comments which makes an old man happy! Now I was able to upload the software (after removing some garbage produced by Visual Studio). Concerning the transformer question from Christan Herr: It can be ordered on "http://www.audioelektronik-shop.de/", order BV019/4666 as also mentioned in the General schematics.

Ich benutze die timelib.h aus der Arduino IDE 1.8.5. Siehe auch meine Antwort an "GR CE" weiter oben.

Look at the original post of this project by fuso: https://www.elektormagazine.de/labs/dcf77-emulator-with-esp8266 There I posted exactly the same problem; fuso did upload a modified software which solves the problem: https://www.elektormagazine.de/files/attachment/9889 Furthermore the new software solves another problem which is in the original version: sometimes the emulator hangs up and must be restarted. Since I flashed the new version this issue did not occur any more. Meanwhile I have running three modules with different dcf clocks (one ELV model, the other ones are my own creations, one of them still with a PIC); all of them are working absolutely fine.
