So I setup my Grandfather clock today and I'm getting some annoying audio hum intermittently. When the audio is running the hum disappears but comes back again when nothing is playing. The clock has a lot of moving parts, it runs a servo for a talking skull pendulum using a Scary Terry board. The pendulum swings using a wiper motor and the whole rig runs off an ATX power supply. The audio source is a tablet PC and currently splits using an adapter so one line goes to the ST board and the other to a set of computer speakers. I also tried just using the passthrough on the ST board instead of the spliter with no difference.
I've tried to isolate the problem by keeping all of the power and audio cables as far apart as possible and things seemed okay and then it started up again this evening. I'll try messing around with it again tomorrow as it's too late now and the family needs to sleep. Just looking for any advice on a possible easy solution or any ideas.
Thanks!
