The market is currently flooded with used e-meters. Can anyone recommend something fun to do with a basic resistance measurement device, in the form of a very primitive lie detector?
The funny thing is that the device is so simplistic, there’s no real reason to bother with developing a modern DIY version powered by a Pi or an Arduino.
In the grand quest for world domination, it really feels like the most recent entrants, Scientology and Mormonism, are destined for the dustheap. Even the tired old Catholics are doing a better job. Perhaps the difficulty lies in the secret that gives the Catholics the upper hand — anything started recently enough to be within the realm of recorded history must by default be cleansed, expunged and historically confused until its origins and false doctrine have been obliterated or obfuscated beyond recognition.
