1. For Shits and Giggles: Optimized Sequential Sampling from Multiple Sensors (Arduino)

    By treating sensor sampling as a statistical challenge one can reason about how many samples to take from each sensor given a limited time interval for sampling (eg. 1s). It turns out that 30 samples per sensor is fine, and indeed, even one sample per sensor each second works. But life isn't only about usefulness, read on to follow my messy thoughts and perhaps learn a thing or two along the way.
