Electrical Spike..?

Hope all are well
a question for all the electrical wizards..

Last week I turned on Wonka - and the Mame
Arcade machine turned on, I think it is on the same ring.

over the week I have turned on various machines and no problem.
Today turned on TBL and the arcade machine came on again..

The arcade machine is starndard plug, going into small extension cable in machine which powers a raspberry pie and LCD monitor. The “on. “ button is an arcade button on the back of the machine.

what could be the issue?

Any advice
 
Sounds like a strange issue. Probably related to radial circuit which has polarity issue, where when the circuit is completed via the pinball machine, it is completing the circuit sending essentially switched live to socket where the arcade cab is. It’s defiantly not right. Do you have RCDS?
 
Check the PSU on the mame cabinet assuming it’s a Pc?

You answered your own question, mains spike causing raspberry Pi to switch on. Not all machines cause a big enough spike to switch on the Pi.

Definitely haunted, perhaps you ought to buy a Haunted House to go with it..! :D

Would probably be solved by adding a capacitor to the power in on the Pi or having it on a separate mains ring. Might be worth seeing if the Pi supply is regulated or not.
 
👌 thanks for all the replies.. I’m totally useless with all this stuff. But friend is an electrician so will ask him to have a look at the suggestions to fix.

was worried about blowing up a few pins! :eek:.

thanks again all
