Raspberry Pi internet kill switch

Control the internet in your home with this handy Raspberry Pi Zero W internet kill switch.

Internet Kill Switch!

It’s every teenager’s worst nightmare… no WIFI! I built a standalone wireless Internet Kill Switch that lets me turn the Internet off whenever I want. A Raspberry Pi Zero W monitors the switch and sends an alert via SSH over WIFI to my firewall where another script watches for the alert and turns the external interface off or on.

Internet in my home wasn’t really a thing until I was in my late teens, and even then, there wasn’t that much online fun to be had. Not like there is now, with social media and online gaming and the YouTubes.

If I’d had access to the internet of today in my teens, I’m pretty sure I’d have never been off the thing. And that’s where a button like this would have been a godsend for my mother.

Shared by Nick Donaldson on his YouTube account, the Internet Kill Switch is a Raspberry Pi Zero W–powered emergency button that turns off all internet access in the house — perfect for keeping online activities to a reasonable level. Nick explains:

I have challenged the boys to hack it…

The Raspberry Pi Zero W sits snug within the button casing and is powered by a battery. And so that the battery can be continuously recharged, the device sits on a wireless charging pad. Hence, the button is juiced up and ready to go at any time.

I can pick it up, walk around at any time, threaten the teenagers, and shut down the internet whenever I want, hahaha!

While internet service providers are starting to roll out smartphone apps that offer similar functionality, we like the physicality of this button.

Great job, Nick! Please don’t turn off our internet.
