I was reading up on the blog posts about AC RMS calculations you had up earlier.

Could it be caused by processing lag?
I did leave the cycle and sample to auto, not sure how many sample points are needed for the logging function to work.

Is there a way to have it dump the untouched/processed 24bit data it gets from the other chip when logging?

Also noticed that the batteries are now down to 50%.
Is it possible to buy just the shell (I’d like to make a non-AA powered adapter of sorts)
