The goal is to gut the 70 year old electronics and re wire the switches to activate motors. It will give you a buzz but no actual pain.Funny you should post this, I'm about to start working on the exact same thing! Except I don't have a genuine PH Meter, they're nearly impossible to get for a reasonable price here in Australia (the shipping alone is painful). So I found a vintage ~1960s Japanese wattmeter in a nice wooden box. This would be for the South Australian Ghostbusters, so I need to gut the electronics to keep it lightweight for events (it's about 6kg/13lbs).
I spent several weeks researching whether it would be possible to actually shock participants in a safe way. The German Ghostbusters use a TENS Machine, I also looked at repurposing a prank electric shock pen or one of those shocking board games. The TENS Machine isn't cheap, and those shock toys could still cause someone injury (heart attack or nerve damage), I read a lot of horror stories in the news. Plus with everyone using hand sanitizer, creating a spark isn't a good idea. Finally, you have to keep buying replacement disposable pads.
So I'm planning to do the vibration motors too, I think the anticipation of getting shocked is probably scarier than actually getting shocked. Also more fun for the people watching. I'm on a deadline (mid-November) but I'm still hoping to get a nice loud sparking sound to play when the button is pressed.
I might create a build thread here somewhere so I can share what I do, including the electronics and the playing card artwork, how I'm marking the cards, and there may be some 3D printing involved too.
