You know a "secret tech" conspiracy theory story is total nonsense when it's debunked by a fringe supernatural research journal...

The first rule of analog computers is that you should not use a differentiator unless it's absolutely necessary, because it's physically a high-pass filter and amplifies high-frequency noise.It's amusing that the same lesson also applies to digital signal processing. Differentiate a signal without filtering or interpolation gives you total garbage. The quantization noise of the ADC can make the problem even worse than analog, every code jump is a sudden change and creates a spurious spike. #electronics

Another unbelievable circuit hack: abusing an ordinary DC-DC power chip to achieve microamp-level quiescent current, an application the chip was never designed for. The chip's own control loop is bypassed entirely, the feedback pin is disconnected. Instead, voltage regulation is done by turning the chip ON and OFF continuously via its CONTROL pin from an external opamp error amplifier. #electronics
