Going to try out a new measurement filter at the coffee roaster. The hardware that I'm using isn't quite as nice as what I used to have there (which is no longer supported on anything other than Windows and maybe in theory some very specific but obsolete version of Linux/distro) but the sample rate is high enough that I can apply statistics to the problem. Did a test run in a spreadsheet to work out starting parameters, but I'll feel better seeing if it works live.
