ME 218a Final Project:  L.A.S.E.R.

"Light Avoidance for Simulated Explosive Removal"

Quickly agent! A nefarious villain has set a bomb inside of this vault. We're relying on you to neutralize this threat as quickly as you can:

  1. Unlock the vault by turning the dial to the correct numbers
  2. Defuse the bomb by pressing the correct buttons – but make sure to avoid those pesky lasers

And agent – be sure to watch that timer!

Operation of the L.A.S.E.R. Training Device


Deploying the device:  Supply both 9V and 5V power, then flip on the power switch. The start button will illuminate and the 1997 Goldeneye video game music will play over headphones.

To start the game, push the start button.

The power switch is located on the right side of the game.

Unlocking the Vault Door:  The correct vault code will flash on the panel on the far right, and the current position of dial will appear on the left side. Make sure to remember the vault code!

In the example the sequence is 7-3-9. Turn the dial in the direction of the > arrow until you hit the number 1. For each number in the code, switch the direction the vault dial is turning and turn until reaching the correct number. After reaching the final number, simply switch directions one last time and spin the dial to complete the unlocking sequence.

Success will be indicated by the appearance of exclamation points !!!

​What happens if the user enters the combination incorrectly?  Well, the LED matrix will display large "X"s (shown in the image to the left), and after a short period, display a new combination for the user to attempt.


Defusing the "Bomb":  When this phase begins, the user has 60 sec to complete the correct button sequence. Press each button as it lights up, making sure to avoid the lasers that illuminate on the bottom and side.

Here are several pictures illustrating how the illuminated buttons change after being pressed:

There are two ways to lose a life.  The first is by pushing a button that is not illuminated.  The second is by breaking a laser beam. More lasers illuminate as the player presses more correct buttons.

A death indicator becomes illuminated when the third life is lost, signaling that the player has failed.  Following this indication, an evil laugh sound effect plays through the headphones and the game returns to the starting state.

If the player pushes the sixteenth button with time and life still remaining, they successfully have defused the bomb!  The player is rewarded with a short audio cue of the classic James Bond theme signaling their victory, after which the game returns to the starting state.

Note: The sixteenth (and final) button press is particularly challenging! Can you see why?
