This College Student Has Been Hilariously Trolling His Friends With A "Seinfeld" Door Sensor

"Now just grease the floor so people come sliding in like Kramer."

Posted on October 11, 2017, at 1:14 p.m. ET

Evan Genuise, 18, is a freshman at Northern Arizona University where he's pursuing electrical engineering and computer science.

About a month ago, Genuise came across a YouTube tutorial from user Chloe Alix demonstrating how to install a motion sensor that triggers the Seinfeld theme/riff. "As soon as I saw the video I wanted to make one," he said.

"I thought it would be hilarious to rig my dorm with a sensor that played random transitions from the Seinfeld show," he told BuzzFeed News.

He had an extra Arduino board (as instructed by Alix's YouTube video), and gathered the rest of the required parts.

It took him about a month of trial and error to have it installed successfully.

Last week, after successfully rigging it on his dorm door, he filmed his friend walking in and captured his priceless reaction.

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.

It's Seinfeld, IRL.

The sensor has inspired evil-genius, troll-y friends everywhere. "I want one with a proximity sensor that says SOME when somebody's outside and then - BODY ONCE TOLD ME once they open the door."

People got very imaginative. "Imagine walking in on ur bf/gf cheating and hearing the Seinfeld bass line."

As far as using your education and powers for good and evil, the bar has been set quite high, according to Twitter.

Lmaoooo this is going in my first house

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.

Genuise became friends with Foster in marching band during his sophomore year of high school. He said Foster had been working on a portable Nintendo 64 project which "blew my mind," he said.

"Stephen was an incredibly helpful person," he said. "Without him, I'm not sure if I would've ever gotten into electronics. I owe it all to him."

"Stephen would have loved the Seinfeld sensor," he added.

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.

YouTube instructor Chloe Alix told BuzzFeed News if anyone is extra curious about her own tutorial, among other functions, she's even engineered and coded her equipment so they "trigger a smoke machine while playing air horn sounds."
