Just an ordinary evening attaching oscilloscope probes on the exercise equipment...
Decoding the quadrature signals with timestamps on the falling edges and analyzing a 2km row shows the power curve for every stroke.
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.
