Exhibit: Solve the fall

Important info for management
No info for Maryanne at this time

Exhibit startup:

 * Turn on the displays for both rigs. Press button located at bottom middle of the display. When the display is incorrect, notify engineering to reset program.
 * Turn on the lighting in each tower. Located in each tower is a small box with a slider button. Slide this slider button until the desired amount of light is reached.

Exhibit shutdown:

 * Turn off the displays for both rigs. Press button located at bottom middle of the display and a circular menu will appear. The button is also a joy stick. Pull the button towards you (selects turn off).
 * Turn on the lighting in each tower. Located in each tower is a small box with a slider button. Slide this slider button until the lights turn off.

Initial problem resolution to be performed by staff:
None at this time.

Common problems to be resolved by staff:
None at this time.

Additional Training required for staff:

 * Raising the cube should stop before reaching the winch (in the past, the winch switch has not always worked properly).
 * Ensure broken parts are placed in the broken parts box located inside the door under the left test rig.

Overview:
Each guest is given a cube that contains an accelerometer. This controller / accelerometer is connected to another controller that we call middleman which simply forwards the data from the accelerometer to a PC. The PC then displays this data in a graph and displays the hightest G value received.

Startup:
None. Floor staff performs all startup.

Shutdown:
None. Floor staff performs all shutdown.

Regular maintenance tasks:
None. Components are built and repaired on an as needed basis.

Testing:
To be added later.

Standards used:

 * Black/red/yellow wires follow normal wiring (black=ground, red=hot usually 5V, yellow=data transmission)
 * Ethernet wires: blue=ground, green=hot usually 5V, green & white=data transmission. All other wires are ignored.

Controller: accelerometer
An arduino metro mini and an ADXL377 accelerometer is wired  inserted into each cube that will measure the Gforce impact of the cube.

The source code

Assembling accelerometer

 * 1) Cut a 2 inch piece of cat5 and pull the green, green-white and blue wires. Strip and tin both ends of each wire.
 * 2) Pull another wire. Cut it about ½ inch long. Strip and tin both ends.
 * 3) From the under side of the ADXL377 (accelerometer). Solder the short wire to GND. Flatten the wire against the ADXL377 and position it towards the VIN.
 * 4) From the header pin sets included, snap a 2 pin segment and solder it into the VIN and AREF of the metro mini pictured above.
 * 5) From the header pin sets included, snap a 3 pin segment and solder it into the A2, A3 and A4 of the metro mini.
 * 6) Place the ADXL377 VIN over the metro mini VIN and solder the header pins (VIN, 3V, Z, Y, X).
 * 7) Solder the ADXL377  GND wire to one of the metro mini's GND.
 * 8) Solder the green-white wire to the metro mini pin number 3.
 * 9) Solder the green wire to the metro mini VIN.
 * 10) Solder the blue wire to the metro mini GND.
 * 11) Solder a female RJ45 connector to the other end of these wires. See previous instructions for the female RJ45. Gaffer tape and plastic piece are not needed.
 * 12) Load the metro mini with the solve the fall program.
 * 13) Test the accelerometer on the test rig.
