I'm no math expert, but the factory computer on this rowing machine seems to have an impossible situation: 10 minutes of exercise at an average 26 strokes per minute is much higher than the 187 total strokes. My recording of the same workout shows almost the same count of 189 strokes and a cadence closer to 19, which checks out.

p5js + websockets from the esp8266 makes for a nice realtime visualizer cadence and power. A fake phosphor effect on the force curve shows how closely each stroke matches the previous few.


Decoding the quadrature signals with timestamps on the falling edges and analyzing a 2km row shows the power curve for every stroke.

Just an ordinary evening attaching oscilloscope probes on the exercise equipment...

Laserdiscs have wonderful covers like vinyl records, although they don't have that warm analog sound.
