CANarchy is a versatile CAN-bus experimentation tool. It comes as an easy to build DIY kit and is fully open source. Your userfriendly CANbus hacking tool.


For a research project a bunch of kids needed a tool and I designed this to help them reach their goal. Turns out, this is really handy and people use it for all kinds of things.

  • Did you ever want to get rid of the speedlimit on your E-Bike?
  • Submit you Cars data over the Internet via MQTT in Realtime?
  • Repurpose that old Scooter or Battery you found for cheap at an auction?
  • Make the elevator access a floor that is not available to you via buttons?
  • Log a large number of CANmessages to a microSD Card for further analysis?
  • Reply recorded Logs?
  • Send custom Answers to Queries on the CANbus?
  • Open that lock at the push of a button?
  • Do ANYTHING that CANbus can do?!

How can it be so cheap?

I am noting making any profits here.

I am a strong supporter of OSHW and my work would be impossible without the work of those that came before me and let me learn trough their sharing of ideas and code. Especially the GNU movement was of great importance in my life. I am now giving back as much as I can to the next generation of hackers.

*If you can't afford a CANarchy kit for any reason, Please let me know and we will find a solution to get you started. *
