Internet Lag Simulator

💡 Inspiration We were in a Zoom meeting, someone got called on, and they just froze—literally and figuratively. The classic:

“Sorry… I think my connection is unstable.”

That’s when we realized: faking bad internet is an art. So we made it a science.

📺 What it does Internet Lag Simulator lets you fake terrible internet during video calls.

Freezes your webcam at the worst moments

Makes your voice cut out or glitch like a robot

Gives you the power to vanish from meetings — without ever leaving

Perfect for students in class, workers in meetings, or introverts on a call.

🏗️ How we built it We combined:

A virtual webcam that drops frames, pixelates your video, and freezes you mid-sentence

A virtual mic that injects robotic distortion, dropouts, and lag

Toggleable modes: video-only, audio-only, or full disaster mode We used OpenCV, PyAudio, and virtual device drivers to pull off the chaos.

🐛 Challenges we ran into Making the lag feel just real enough to fool teachers and managers

Syncing audio and video glitches so it didn’t feel too fake

Getting Zoom, Teams, and Meet to accept our virtual devices

Accidentally pranking ourselves during testing. Oops.

🏆 Accomplishments that we're proud of It actually works — and people genuinely believed the lag

We made fake Wi-Fi a feature, not a flaw

We turned “technical difficulties” into a button

📚 What we learned How virtual cameras and microphones work under the hood

Real-time audio/video processing techniques

Bad UX is sometimes... the best UX (on purpose)

🔮 What's next for Internet Lag Simulator Mobile version (for “sorry, I’m lagging” on the go)

“Boss Mode”: instantly triggers lag when your name is called

Auto-detect boredom levels and lag accordingly Because sometimes, the best way to show up… is to not show up properly.
