[work] Always a great sign when doing what should be a routine check produces a result that makes you go "what the fuck" out loud in the office
I'm doing an ADC calibration for some new microcontroller boards we bought in. Comparing the measured voltage with the real voltage is supposed to give you something like this 
The difference should be a nice, steady proportion you can use as a correction factor
I just plotted the voltage offset for the new boards and got THIS 
what the FUCK am I meant to do with that
seems pretty dangerous
