Evan Genuise, 18, is a freshman at Northern Arizona University where he's pursuing electrical engineering and computer science.
Last week, after successfully rigging it on his dorm door, he filmed his friend walking in and captured his priceless reaction.
I build a door sensor for my dorm
Genuise has been trolling his friends and visitors since. He said he plans to keep the sensor on his door "forever — This shit is hilarious."
People online have hilariously imagined this exact plan playing out over the next four years of their college years, and how annoyed his friends will become.

Genuise said he's glad others are now inspired to learn about electronics while having fun. He said he was greatly inspired to explore and experiment with gadgets by his late friend Stephen Foster, who died in a car crash two years ago.
BuzzFeed News has also reached out to YouTube instructor Chloe Alix for reaction to this IRL application of their mastermind creation.
Look what you've done, Chloe Alix.
