State so far:

 - Built a wooden stand for the motor
 - Powered the controller and display from RD6024 PSU.
 - Generate a PWM from Arduino to simulate PAS sensor.
 - Blew the RD6024 PSU when the motor stopped getting power and back EMF produced a spike.
 - Repaired RD6024 PSU. Added diode in series to prevent the back EMF from blowing the RD6024 again.
 - Blew the display when the motor stopped getting power and back EMF produced a spike.
 - Depotted the controller for analysis.
 - Figured out to turn on the controller with the SW pin to run controller without display.
 - Replaced soldered connections with 2.0mm female headers.
 - Simulated throttle with potmeter on SPGND, SP5V, SP.
 - Flashed controller with EBiCS opensource firmware.
 - Blew 2 FETs due to running controller without heatsink.
