Thats a very good idea, thank you ill look into it!

Mit dem BPM part will ich sicherstellen das es sich wirklich um musik handelt, und dachte daran das klopfen jedesmal im selbem BPM wie die musik zu machen aber mit phasenversatz, quasi wie ein echo

I tryed with the magnetometer in my phone before and sadly it didnt pick up anything, i think the polling rate may be to low too. But ima search around for some more sensitive hall effect sensors

Yeah very very much so, for years, they only shut up when i bang the sealing, they love loud EDM at 3am in the morning and i kinda wana automate the sealing banging part now.

Interesting, i didnt knew those existed at all, but thx for the suggestion i will try one of those!

Directional gets kinda tricky in the low frequency range :/

Yes i found the wire going to the light bulb, it isnt connected to anything rn, because the new motor dosent have a plug for it, and i dont need the lamp to work.

What would speak against the second plug solution (besides it beeing anoying)?

identify capacitors on the circuit board

No such thing in there, this is a very old machine there is no electronics inside the machine. The only electronics is the motor itself (bolted to the outside), and the foot pedal that controls the motor (wires go from mains to pedal to motor, there are no wires going inside the machine).

I did measure the current

And apparently there are 30-32V AC on the metal body of the machine :( Then i tested the current and it was 4.1uA.

GCD?

I cant change the plug, because it goes strait into the pedal. The pedal nor the motor has a grounding connection sadly.

I now grounded the machine using a second plug and it works…kinda anoying because i now need 2 plugs to use the machine, but better than nothing.

I now used a second plug that has a grounding pin and connected the ground to the Machine body and now there isnt any voltage on it anymore. The RCD also didnt trip so i guess everything is fine and it was just parasitic induction.

No i used the new screw that came with it, but its actually shorter than the old one, i dont think its touching anything on the inside, the screw hole is just a blind hole in the metal body.
