Software

Arduino 1.8.1 with "NodeMCU 1.0 (ESP-12E Module)" board - added as per this instructable.
Processing (maintained by Ken, not currently versioned)

Sensor

Adafruit 9 DOF IMU BNO055 overview and github repository

Wifi radio

NodeMCU - Arduino compatible ESP8266 wifi radio

Arduino code

Two BNO055 and NodeMCU setups are used, one running sketch
Arduino/imu_arduino_blow,
the other
Arduino/imu_arduino_hand.

Note server ip address and wifi network and password details must be edited in the above sketches as required.

PHP code

Read (Processing script relaying to PLC) and write (NodeMCU sketches) are serviced by
cloud/studio-ini.php.
For testing (29 and 30.08.2017) php code ran on Ubuntu 16.04 running Apache, the server itself running as a virtual machine on Amazon Web Services.
