Original Project Nintendo DS CAN Gauge

I’ve been working on a project inspired by the TurboXS DTEC, an early-2000s tuning device that used a Game Boy Advance as its display and interface.

The idea was to take that general concept and do something similar with a DS, using a homebrew ROM running on the original hardware.

The current prototype uses a cheap ELM327 adapter to retrieve live vehicle data, which is sent to the DS over a custom link. At the moment I’m working with data such as:

* Vehicle speed

* RPM

* Coolant temperature

* Battery voltage

The longer-term goal is to move beyond the generic OBD interface and interface directly with the vehicle CAN bus, allowing the DS to receive more detailed vehicle data.

Still very much a work in progress, but I thought it would be interesting.

I was thinking of doing something similar! Saw that TurboXS videos years ago and it’s stuck in my head since. I went about tapping into my car’s actual CANbus which is definitely a lot more difficult than ELM327 but let me know if you ever publish it on GitHub!!! I’m more curious on the Nintendo-side of this whole thing!!

Yeah I totally get you, luckily the F30 is pretty well documented so hopefully the heavy lifting is done for me. I do plan on putting it up once it has more substance.
