    SPOILER:
    A tutorial on how ESD protection diodes in chips work and how they can be used, mostly inadvertently to power a chip through the input and output pins without having the power or ground pin connected.
    This example uses an MSP430 microcontroller, but is applicable to almost any complex or simple CMOS chip.
