I think the YouTube algorithm just picked you up, because this showed up first on my recommended lol well done

[csongorvarga]

Uh thanks. Great work. I was just about to start a similar project. I should order your board for this.

[Jackisaboss]

Awesome! I’d be interested in learning more about the PCB design process for the shield (i.e. how you decided on resistor/capacitor/inductor networks for the ICs)

[FrankGraffagnino]

can't wait to try this... and i didn't know Teslas didn't have an OBD port... i thought they had to have one by law? anyhow... great job!

[RoamingAdhocrat]

took me a good while to get my head round the difference between an ESP32 chip vs module vs dev board

[voltlog]

As far as I know a CAN network must have termination resistor present at the two physical end points of the CAN network. The circuit that you have designed seems to have a hardwired 120 ohm resistor which is introducing additional termination resistance against the CAN standard (as the car network already has termination resistors in place). Do you think this can cause any issues with the particular CAN network the shield will be connected to?

[mesunandan]

How did you know which CAN message ID and which bits out of them are responsible for the velocity data or any other variables? Did you have the DBC?
Have been trying to do the same for indian cars using my arduino with sparkfun can shield and kvaser CAN bus monitors. But I can only see a single ID and stuck with how to extract more CAN messages!

[yudhahamdiarzi]

I subscribed, hope can learn a lot about CAN protocol :D

[rchilro]

Great job!!! Just a suggestion, can you add a video or a description where you got the speed display and how you attached it? It would be wonderful!

[Ydooo]

show more how did you do this indicator?

[ChuckNorris-eimk]

Could you please make a DIY on how to make active spoiler with some RC Car servo motors? Based on speed and break. Like from a gps module or IMU sensor

[soupbowlbandit]

Now wi I be able to take your board with the 32 and use it to activate a relay board with low power outputs?

[tkcrmzk]

Hello. how to convert analog signal to can signal? I have an android vw radio with can support. I want that when the car door is opened (negative signal), it will be converted to can and the car radio will display the door opening on the display.

[waelbadr]

I have a can bus arduino shield how can I use it

[AutoRevLife]

This is very cool! So i can wire this into any car and check the data wirelessly on any device?

[ricksdunnn]

where can we get the ODBII cable interface?

[yasirshahzad]

can we change the fuel settings in cars using CAN bus?

[SahaParikshit]

which version of CAN does it provide? can i use it with canopen ros ?

[giannisalevizakis]

Best channel ever, best project ever. The thing is how do you translate the CAN BUS messages?

[irieblue]

Very nice! I thought Tesla had switched to "Automotive" ethernet vs CANBUS. What is that neat Display you are using to display the information? Great job!
