 ===== Setup =====
-Suspend the diffuse light source above the rotating table.  Attach a model exoplanet to the rotating table.
+  - Mount the rotating table on a sufficiently large and sturdy table.
-The light sensor can be placed such that when the table rotates a periodic decrease in the intensity is observed.
+  - Cover the rotating table with a black cloth.
+  - Suspend the diffuse light source above the rotating table.
+  - Attach a model exoplanet to the rotating table.
+  - Connect the power source (EICO 1064) to the motor in the rotating table.
+  - Start at 0V and slowly turn up the voltage until a desired rotation rate is obtained.
+  -  Mount the light sensor a suitable distance away so that when the table rotates a periodic decrease in the intensity will be observed.
+  - Connect the light sensor to the Vernier LabPro interface.
+  - Connect the Vernier LabPro interface to the USB port of a computer with LoggerPro installed.
+  - Power the interface, wait for the beeps to finish and then start the LoggerPro software.

 ===== Notes =====
-This setup involves many pieces and the setup is involved and potentially involves more than one person.
+This demonstration was originally a PHYS 420 project.
-Please give plenty of advance notice of when the demo is needed and what room it will be needed in.
+Please see the dedicated PHY420 page: [[ https://phys420.phas.ubc.ca/p420_2022/ezezenth/ |  https://phys420.phas.ubc.ca/p420_2022/ezezenth/ ]]
-A computer is needed that has LoggerPro installed.  Please speak to the demo room assistant if LoggerPro is desired on your personal laptop.  Henn 200, 201, 202 and Hebb Theatre (Hebb 100) have LoggerPro installed on the Room PC.
