BusKill USB-A Decoupler V3 Build and Demo

Latest update for my project to provide an open source design for a BusKill cable. Status In my last update, I shared the instructional video I created that will be part 1/2 videos that show the decoupler’s assembly. The decoupler created while filming the instructional video had a connection that was too weak. I wasn’t

Part I/2 BusKill Video Assembly Instructions

I’ve finally edited and posted the first part of BusKill assembly instructions to YouTube. These instructions cover assembling the breakaway side of the usb-a magnetic coupler. For those just tuning in, a BusKill cable is used with BusKill software to automatically trigger a security action when a USB ejection event is detected. The security action

Exciting milestone in BusKill USB-A Magnetic Release Open Hardware project

Background On July 3, 2023, I successfully created a prototype of the magnetic release. For those just tuning in, this is a project that aims to create a 3D-printable magnetic decoupler that allows for easy ejection of a USB-A extension cord from the USB-A port. This decoupler is used with a PC that has BusKill

BusKill Progress 6/12

For previous work on this project please see: https://crashxblossom.wordpress.com/category/project-updates/buskill/ To speed things along, I have been only printing out the front of the case. I found that printing it in the orientation (shown below) on a raft had the best results. In this image of the back-side you can see that the voids perfectly fit

5/2 BusKill progress

I scaled up the part I made by +10%, and I think this will be easier to work with. As you can see by the variation of magnet orientation, I can choose which orientation I want, and it was a lot easier getting the magnets to behave somewhat… We had an extremely helpful commenter visit

4/29 BusKill Progress

Added 5th wire channel, started channel size adjustments, experimented with printing orientations.

Today the USB Extension Cable White, Costyle 2-Pack 2.0 6ft/2m USB Type A Male to A Female Extension Cord White USB Cable Extender with Gold-Plated Connector that I ordered arrived. I quickly spliced it and behold, this is what I would consider the ideal usb extension cord to work with. Cords vary, and it isn’t

USB cord, why?

So, this really is a strange thing that’s holding up my prototype. It appears there is something to learn about splicing usbs and such that isn’t coming up so far in resources I have tried to find online. Michael and I worked together to try to identify the issue. For background on the project please

Status of BusKill Open Hardware Project

I’ve been working on an open source hardware project for a couple of years called BusKill. It’s a security cord that shuts down a computer if it’s physically separated from you. Quick overview My colleague Michael Altfield and some volunteer developers wrote BusKill software. This software is free and open source and works on Windows,
