Extreme High Voltage: MagLevES Motor v2.0 with Arduino Tachometer

I rebuilt the base and electrode mounts of the maglev ES motor, to match the new pencil-less armature. I am also working on an Arduino sketch for pulse motor control, and here I decided to test the sensor and RPM computation portions of that code. The Arduino and the Strobotac are within three percent of each other at about 5000 RPM, and I think that the Arduino is probably more accurate, since the Strobotac’s dial is hard to read and set at that fast RPM. Usually you would only read to the nearest 20 or 50 RPM on the Strobotac anyway.
The software is recording more than is being displayed on the screen. I am calculating all the individual pulse durations and the intervals between the pulses, but only displaying every 40th pulse’s parameters, and the RPM value is derived from that single pulse, clocking it in microseconds.
