Thanks for the info on the IMU units!
As for your “class detection” idea, I was thinking that with the wave form screen idea I had, change that to something like the waveform mini-game from Star Trek Online. If you haven’t played that game in the past 10 years or ever, there’s a game where you have to match wave forms. With my meter, I was thinkin you turn either the red or gold knob to match the on screen wave frorm and once you lock it in, the screen would give you a “class 3/4/5” in one of the corners of the screen. I dunno, that’s down the road for version 2 or 3.
