DIY LED Shift Light: CAN Bus Hack

can you give the brand of the can transceiver you used? Can you share any of the arduino code? that is, if you aren't planning on selling it. I use arduino's pretty extensively, and am super interested in your progress. Great job dude!

Hey! Yea! I used a SN65HVD233-HT3.3-VCAN Transceiver. I didn't use an arduino but rather a Texas Instruments Tiva C Series TM4C123G LaunchPad. It's what I used in school and it's half the price, a lot faster, and it comes with a CAN controller built in, you just need the separate CAN transceiver.

I'm hoping to make a blog about my project soon and will post the source code as well for you enthusiasts!

An Update!

It's been a while since I got to work on this side project, but here's an update!

I finally ordered the rgb led arrays that will work as a shift light that will reflect onto the windshield, acting as a tachometer HUD.

In the meantime I saw some graphics of the 2017 Ford GT and I just loved the instrument cluster, so I decided to replicate it using some HTML and CSS and hooked it up to my uC. If I can find a smaller display that can fit between the steering column and the dash, it could potentially be a working instrument cluster Here's what it looks like:

Thanks for posting the parts! ace!:cheers:

Wow, impressive!!

any updates? this is awesome.

More coming soon!

YUP

any other updates?

Oh snap. Subbed. Very interested to get this going. Can you release code?

also sub'd

Cool project. Any updates?

I have a buttload of Arduino stuff and 2 rolls of ws2812b RGB LED's and 2 3D printers. Might have to get a CAN transceiver and play around when I finish some other projects.

Have you printed with any material that can survive the heat of a dashboard without warping?

That's always tricky. Some cars can get hot enough that even some cheap injection molded stuff doesn't hold up. Polycarbonate would probably be the filament of choice, as it has a much higher glass transition temp than pretty much all other filaments (150C/302F), including ABS, PETG, and nylon. I've never printed PC, personally, but have read that it can be a major bitch to print. I have all the necessary stuff to be able to print it, though.

Finally got around to messing around with this. Used an Arduino Pro Mini (5v) and a Freematics OBD2 UART adapter. I used a small OLED display for testing. Tested engine RPM and speed and worked great. Should be really easy to hook up an RGB LED strip and control it based on RPM. Stay tuned

I'll give you a cookie if you figure out how to use the MyColor LEDs as the shift lights.

Green when normal, red for shift.
