BusKill Now Shipping!

We’re excited to announce that our first production run of BusKill cables is now in-stock in our distribution center. Existing orders are going out now, and new orders will ship immediately.

[BusKill] Our Dead Man Switch Magnetic Breakaway cables are Now Shipping!

The first BusKill prototype was born in 2017. It gained international popularity in 2020 when Michael Altfield described how to build your own BusKill cable. After extensive effort and with the help of several contributors, a Linux hacker’s DIY cable got a user-friendly, cross-platform GUI.

When the only USB-A magnetic breakaway coupler on the market became out of stock and EOL’d, we raised $18,507 on CrowdSupply in early 2022 to manufacture our own injection-molded cable. One thousand logistics challenges later, Mouser started shipping BusKill cables to our backers in October 2022.

Now that the hardware is out the door, we’re hard at work on new features for the BusKill app. Our top goal is to add a soft-shutdown trigger to the existing lock-screen trigger. At the time of writing, this is functional on Linux and Windows. We’re just working out the kinks of privilege escalation on MacOS.

To be notified when we’ve added the soft-shutdown trigger to the BusKill app, you can signup for our newsletter.


We did our best to test BusKill across the three target platforms, but the wide spread of OS versions does leave room for error. If you happen to find a bug with BusKill, please let us know.

If you don’t have a BusKill cable yet, you can buy one here on this website or build your own. And for the makers out there, checkout the progress on our 3D printable BusKill magnetic breakaway coupler 🙂
