Getting Ready for Prime Time

 refers to an unmarked and repeatable quest in the Fallout 3 add-on Broken Steel.

When asking Scribe Rothchild how you can (further) help the Brotherhood, he requests that you bring him sensor modules and old cameras to help fix Liberty Prime.

Walkthrough
Once you have completed the quest Who Dares Wins, you can accept the quest by talking to Scribe Rothchild. You can get started by finding some cameras and sensor modules. These items can be found in most toolboxes and near workbenches. Once you have obtained at least one and preferably as many as your carry weight allows (for efficiency's sake), you can return to Rothchild for a reward of 100 caps and 25 XP for every camera. For every sensor module you turn in, you receive 75 caps and 10 XP. These are not awarded until after exiting dialogue with Rothchild.

Reward

 * 100 caps and 25 XP per camera
 * 75 caps and 10 XP per sensor module
