Those who have children of their own might argue that the youth of today are getting far too much internet time. [Nick] decided to put an emergency stop to it and made this ingenious internet kill switch to threaten teenagers with. Rather unassuming on the outside, the big red button instantly kills all network traffic as soon as you push it down, doing its label justice. Reset the toggle button, and the connection is restored, simple as that.
In order to achieve this, [Nick] fit inside the enclosure a Raspberry Pi Zero W, along with a battery and a wireless charging circuit for portability and completely wireless operation. The button is wired into the Pi’s GPIO and triggers a command to the router via SSH over WiFi, where a script listening to the signal tells it to drop the network interfaces talking to the outside world. It’s simple, it’s clean, and you can carry it around with you as a warning for those who dare disobey you. We love it.
Another use for big red buttons we’ve seen in the past is an AC power timer, but you can do just about anything with them if you turn one into an USB device. Check this one in action after the break.

[Dave Astolfo] wanted to be able to let his CNC mill run by itself with the ability to monitor it remotely. The only problem with that idea is that if he checked in and saw something bad happening he needed a remote kill switch as well. He ended up killing two birds with one stone by adding extra features to an IP camera.
These Internet Protocol cameras are pretty nifty. Just plug their power cord in and they’ll connect to WiFi and start streaming video. Many of them offer features like pan and tilt, and this model even features IR LEDs for night viewing that can be switched on and off through the web interface. That’s the point at which [Dave] started his hack. He patched into the leads on the IR LEDs. They’re monitored by an ATtiny85. When he turns on the LEDs via the webpage the ATtiny85 senses it and drives a servo motor to push the ESC key on the keyboard. As you can see in the clip after the break, this will stop the milling in its tracks. We especially liked the use of LEGO Technique pieces to make the servo mount removable.

[Ray] had a Guitar Hero controller for PlayStation 2 sitting around. Because he moved on to playing the game on Xbox 360, he decided to cannibalize the older controller for its parts. He removed the strum bar and fit it inside of a mid-1980’s Peavy Patriot electric guitar. Once wired up, it works as a kill switch; it stops all sound from making it to the amp whenever the strum bar switch is actuated. Don’t miss hearing this effect in the video after the break and keep sending in those Guitar Hero mods. Continue reading “Guitar Hero Strum Bar As Guitar Kill Switch”
