We’re happy to announce that, for the first time ever, BusKill cables can be purchased in-person in Leipzig, Germany.
The BusKill project has partnered with ProxyStore to make BusKill laptop kill cords finally available from a brick-and-mortar location. You can now go to the following location and purchase a BusKill cable with cash or cryptocurrency.

We’re happy to announce that we were successfully able to initiate a BusKill lockscreen trigger using a 3D-printed BusKill prototype!
While we do what we can to allow at-risk folks to purchase BusKill cables anonymously, there is always the risk of interdiction.
We don’t consider hologram stickers or tamper-evident tape/crisps/glitter to be sufficient solutions to supply-chain security. Rather, the solution to these attacks is to build open-source, disassembleable, and easily inspectable hardware whose integrity can be validated without damaging the device and without sophisticated technology.
Actually, the best way to confirm the integrity of your hardware is to build it yourself. Fortunately, printing your own circuit boards, microcontroller, or silicon has a steeper learning curve than a BusKill cable — which is essentially just a USB extension cable with a magnetic breakaway in the middle.
Mitigating interdiction via 3D printing is one of many reasons that Melanie Allen has been diligently working on prototyping a 3D-printable BusKill cable this year. In this article, we hope to showcase her progress and provide you some OpenSCAD and .stl files so you can experiment with building your own and help test and improve our designs.

Last month, I successfully triggered a lockscreen event using our 3D-printed BusKill prototype.
We’re happy to announce that we’ve had good progress on the design of the 3D printable BusKill USB-A magnetic breakaway couplers this year!

A few years ago, Michael asked me if I was interested in developing a 3D-printed case for the magnetic breakaway. He enumerated the following design requirements:
However, over the past years’ iterations, we adjusted the requirements:
In celebration of Bitcoin Black Friday 2022, we’re offering a 10% discount on all BusKill cables sold between Nov 19 to Dec 04.
We’re happy to announce the release of BusKill v0.5.0
You can upgrade your BusKill app to the latest version either by
We’re very excited to announce that BusKill cables are now available for purchase via CrowdSupply!
This week we launched the BusKill crowdfunding campaign on CrowdSupply.
The DIY guide to build a BusKill laptop kill cord was released last year. Designed to protect journalists, activists, travelers, and crypto traders — this USB Dead Man’s Switch can trigger your computer to lock if someone physically snatches your computer away from you while you’re using it.
You can buy a BusKill cable today from CrowdSupply:
You can also buy a BusKill cable with bitcoin, monero, and other altcoins directly from our BusKill Store:
This post will introduce a simple udev rule and ~$20 in USB hardware that effectively implements a kill cord Dead Man Switch to trigger your machine to self-destruct in the event that you’re kicked out of the helm position.

Let’s consider a scenario: You’re at a public location (let’s say a cafe) while necessarily authenticated into some super important service (let’s say online banking). But what if–after you’ve carefully authenticated–someone snatch-and-runs with your laptop?
Maybe you can call your bank to freeze your accounts before they’ve done significant financial harm. Maybe you can’t.
Or maybe your laptop was connected to your work VPN. In less than 60 seconds and with the help of a rubber ducky, the thief could literally cause millions of dollars in damages to your organization.
Surely there must be some solution to trigger your computer to lock, shutdown, or self-destruct when it’s physically separated from you! There is: I call it BusKill.
