Did you really have to acid etch a chip package to find this out? Can’t you measure current/voltage across the microphone?

- monsieurbanana 6y agoThe reverse engineering work here showed that "LED is electrically tied to the signal which controls the microphone's power", which means there's no software way to turn the microphone on while keeping the LED red. Measuring the current of the microphone would only tell us that at a specific moment, the microphone is off and the LED is red. But that might be a software switch, in which case nothing would prevent Amazon to turn the microphone from time to time while keeping the LED red.
