A Game Boy Speedometer, just because you can.
The “world’s worst digital dash”, a Nintendo Game Boy as a digital speedometer. Interfacing the handheld with the vehicle’s CAN bus system, this project has something to offer.

![Months of work have gone into decoding the Game Boy’s data bus and creating a schematic for the interface board. Tricking the Game Boy into thinking it was loading a game, while actually displaying incoming speed data. The screen’s low resolution and slow refresh rate rendered it barely readable in a moving vehicle. But [John]’s goal wasn’t practicality — it was just proving it could be done.](https://nerdculture.de/system/media_attachments/files/114/251/391/317/762/186/original/f1ea811e6cb4c4c3.jpeg "Months of work have gone into decoding the Game Boy’s data bus and creating a schematic for the interface board.

Showing real-time vehicle speed on the Game Boy sounds like it should be relatively easy, but the iconic game system wasn’t exactly built for such a task. Its 2 MHz CPU and 160×144 pixel dot-matrix screen were every kid’s dream in 1989, but using it as a car dashboard is pushing it. To bridge that gap, [John] designed two custom circuit boards.
One interfaces with the Game Boy, intercepting its memory requests and feeding it data from a microcontroller. The other processes the CAN bus signals, translating speed information into a form the Game Boy can display. [John] used inexpensive tools and software to read the CAN bus data, and used GBDK-2020 to write the software in C.](https://nerdculture.de/system/media_attachments/files/114/251/392/340/955/496/original/f54a186d63357559.png "[ImageSource: John Sutley]

With the Kali Linux 2025.1 release, i'm happy to said that CAN Arsenal as been released as well!
https://www.kali.org/blog/kali-linux-2025-1-release/
Here is a quick demo of @kalilinux #NetHunter CAN Arsenal. Im using a CAN USB Analyzer and Arduino with a CAN bus shield to emulate Car signals.
As its Experimental, you may face issues. If needed, contact me for guidance!

Version 1.1.0 of CANnectivity, an #OpenSource USB to CAN adapter firmware based on @zephyr, is now available!
This release is based on the just released #Zephyr v4.1.0 and brings, among other things, explicit support for a number of popular USB to CAN adapter boards.
More details available in the #CANnectivity v1.1.0 release notes: https://github.com/CANnectivity/cannectivity/releases/tag/v1.1.0

I published my Documentation of CAN Arsenal for @kalilinux NetHunter
https://v0lk3n.github.io/NetHunter/CAN-Arsenal/documentation
It should be released as experimental version in 2025.1!
I will keep updating it and add functionality to it!
You can also find it in Official Kali Linux Documentation :

I will talk about #realtime Linux kernel support, applications and history at #FOSDEM 2025 based on our experience at #CVUTFEL and my company for robotics, automotive communication ( #CANbus ), etc. The talk is based on my last year Czech language talk for the local community (Slides in English) reporting about PREEMPT_RT mainlining. Discussion and suggestions for slide fixes/extensions are welcomed as my talk has been accepted as no other better has been offered by more knowledgeable developers.

A detailed analysis of SECoC key extraction methods reveals potential vulnerabilities in automotive systems, highlighting security challenges and solutions.
Kennt jemand eine gute #CANBUS-Dokumentation für Kfz, speziell VAG?
And no, #SpaceCan is not a bucket of tin or similar. Its a space #CanBus! #autohacking #spacehacking
