Hi Morgan and all friends from the forum.
Whell, yes my zahorie, without the box, can hear the noise from my tv from about 2 meters.
Tomorrow i will place the hole circuit on a wood box. Then after that i will take a video to show you on youtube.
I still don´t know what are the setting for the 3 variable resistors and also what sound should i expect from zahori.
I belive that when you get close to a 220 volts AC , 50 hz, is normal to hear a current noise coming from the buzzer.
So if anyone has more practice and expirencies with it, let me know what should i look to know if this is working or not.
The circuit was checked 3 times and looks fine.
I hope someone can help me to understand this, that looks very nice project to try and experiment.
Regards
Nelson
