#12There is a subreddit where people measure the radiation given off by random things you'll see them pointing some device at the ground or an object.

#13Do a search for "MightyOhm Geiger Counter Kit Bundle" and you will find a stand alone version of the same circuit along with photos. Although the PCB has a "High Voltage" label, it is powered by 2 X AAA batteries which are might be very lethal if ingested.\s

but how many amps though?
How many is safe? I don't mean that facetiously - do you have a good understanding of a safe power limit on a source at hundreds of volts?
Depends on the specific conditions but less than 2mA for AC should only be a tingle and closer to 5mA for DC will be a slight tingling.

#17I wonder if a device with worse RAM can measure radiation by checking how many of its own bits are being randomly flipped.
Coding a program that could self-heal and survive in such a situation would be fun.

#18I know that footguns are broadly "on-brand" for the flipper zero ecosystem, but exposing high-voltage leads like that without any warning whatsoever seems a bit much .
About the same voltage as a carpet shock.

> less than 2mA for AC should only be a tingle
Yep, and even with AC, it depends on the frequency. There are a ton of variables affecting how dangerous electricity is to people, so it's hard to make general statements about it.
