How do I disable the project?

Hint 1 of 8:

You'll need to find the controls first.  See the previous question if you
haven't done so already.

Hint 2 of 8:

Breddell has also hidden the code to the project.

Hint 3 of 8:

It's also in his room.

Hint 4 of 8:

Pick up the book on his table, and a strange bookmark will appear.

Hint 5 of 8:

It's more like a circuit than it is a bookmark.

Hint 6 of 8:

Perhaps you can read what's on the circuit.

Hint 7 of 8:

Use the science tricorder to do so.

Hint 8 of 8:

Then you'll have the code.  Use Spock on the controls.
