I Made a Display For My Tesla

[@fgmproductions]

if you are ever going to sell these pre made let me know. I'm in. Thanks.

[@jjonkie]

hats off to you sir ! I was thinking about something like this but you did it and made its much better than i would have done. Thank you !

[@MrBlue-ib7oi]

excellent. i've been looking for stuff like this that can connect with the car.

[@hachogonzalez8649]

Cooool super cool easy and elegant

[@sallerc]

Nice work! I might just order your shield and build one myself (with some modifications) 🙂

[@TwoTeaTee]

You are creative!

[@MatthewKuKanich]

Hey! I've purchased about 8 of your CAN shields and love them but I'm having a pretty big issue. Read mode works flawlessly but ReadWrite mode shows weird behavior. When measuring resistance across CAN H and L I get 120 Ohms in read mode but 0 in read write (soldered the jumper). What's weird is without power but in ReadWrite mode it reads as 120 Ohms but the second it gets powered it drops to 0. The voltage also is off, CAN L reads 0.8v and CAN H reads 3v. Again read only mode works perfect and has them both around 2.5 with no traffic The ReadWrite mode only seems to work properly if it is initialized and serial monitor is running. Otherwise it causes havoc on the bus, all sorts of impedance and voltage issues and it shuts down my tesla completely. It's also shut down a Rav4 and caused the MIL to go off. My guess is that when getting power from the vehicle via the 12v pin the bus isn't initialized in time causing these issues, but it works when it's powered prior to getting connected. I did some more testing and I see you're pulling the RS pin of the CAN transceiver to ground through a 10k Ohm resistor. The transceivers datasheet says a 10-100k resistor puts it into flow control mode but a strong Pulldown to ground puts it in high speed mode. Edit: Bridged the resistor so it enters high speed mode but no difference

[@MrDIYca]

You're right, something is off. If you're seeing 0 Ohms across L and H, there has to be a short somewhere. I just sent you an email-let me know when you have some time so we can troubleshoot this together.

[@MatthewKuKanich]

@@MrDIYca Thank you!! I sent you an email reply

[@sargfowler9603]

Wow, you can actually add stuff to a Tesla that it should have come with from the factory. It'll be interesting to see how many more things you can add

[@MrDIYca]

Integrated LED strip light is next :)

[@olliecarsRoblox]

lots of stuff u can add to a tesla!

[@SanskaariOG]

@@MrDIYca excited for that!

[@greenfrog58]

Great build!

[@dougf94912]

Nicely put together project, thanks for sharing!

[@Histoshape]

Fantastic! I can't tell you how excited I am about people who, like you, implement technical projects. No matter whether car mechanics or electronics. Unfortunately, my 100 interests coupled with a lot of half-knowledge make it difficult to implement my projects 😵‍💫😁 I have currently implemented a Digidash for my old Mini Cooper r53 S. I use a smartphone in a 3d printed housing with an OBD2 dongle via Wifi, car scanner per app & all the media advantages that an Android has. What bothers me is the general latency - start the cell phone or scanner app, connect it to WiFi, connect the charging cable every now and then, etc. Do you think that it is possible with your components to control a circular touch panel and output CAN_OBD2 data as a speedometer? Could apps like Google Maps and music players also be displayed in such a system? I know that everything works somehow, but I would just have to deal with it for years. But I also don't like to just buy ready-made solutions - which don't exist for my old Mini anyway. You're doing great work 👍

[@infty5829]

Very cool project!

[@bigbronx]

why wireless? and why espnow in particular? I guess it doesn't matter if packages are lost, and hopefully there aren't significant interferences around? I was expecting it to be cabled, since the distance is pretty short and both ends are fixed forever

[@knightriderfan1]

If you ever sell these let me know.

[@olaf9957]

Wondering if you can add a speed limiter to the tesla, this option is really missing.

[@BenScott]

This is great but would it have been possible/cheaper to use a Bluetooth-enabled ODB2 dongle? Or are they not fast enough to capture all traffic? And more importantly, is there a similar DBC file for the new Volvo EX30...

[@MrDIYca]

Thanks! ELM dongles can technically read CAN data, but their hardware is quite limited in terms of buffer size, memory, and processing power. As for Volvo EX30, I'm not aware of specific support. However, OpenDBC does have a few DBC files for Volvo, though I can't confirm if they will work with the EX30 - github.com/commaai/opendbc/tree/master/opendbc/dbc.

[@markpirola8152]

Really like this. Are you aware of any circular displays like around say 3cm diameter ?…could look good for this build.

[@MrDIYca]

like this? kzbin.info/www/bejne/iZaVfHaMrqlqea8

[@markdavison3918]

Is it possible to add the garage door opener to the back of the screen with some modifications?

[@loveanimals-0197]

The main things that should be on this screen are all-time-on blindspot sensors (green - OK to turn, or red - not OK to turn), and rear cross-traffic alert if possible. Is that possible to display?

[@MrDIYca]

So far, I was not able to find that CAN message but I know it is there!

[@loveanimals-0197]

@@MrDIYca Where is it reading that CAN message from? i.e where is it plugged in?

[@loveanimals-0197]

​@@MrDIYca There are entries like, " SG_ DAS_blindSpotRearLeft : 4|2@1+ (1,0) [0|3] "" Receiver SG_ DAS_blindSpotRearRight : 6|2@1+ (1,0) [0|3] "" Receiver" BUT, the data is from THREE YEARS AGO - so not sure if this if from the ultrasonic sensors at that time - because current Tesla Model Y doesn't come with sensors - only cameras. So is this data still valid? Could you please check that in your code? Thanks!

[@MrDIYca]

@@loveanimals-0197 I will check it out, thanks

[@loveanimals-0197]

Please let me know if you had any luck getting blindspot date displayed on your setup.

[@seizedgamer]

Will you work on a video on writing data to the vehicle? Such as turning on headlights based or opening charge port as small examples?

[@MrDIYca]

Yes, I shared ( in the members section) a demo where I was able to control the volume, mirrors, media ...etc

[@adamsaiyad3959]

Would it be possible to use this setup for other EVs ? Maybe even a nissan leaf will give it a try and see if I can get it working

[@MrDIYca]

I don't see why not

[@electronics.unmessed]

Nice idea! I made some proposals for DIY analog gauges. May be you want to try one of these to extend your project?

[@simon-yt]

Amazing. I have your CAN Shield 1.1 (older version), is it possible to do it with it too?

[@MrDIYca]

Yes, you just need to wire the OBDII port by hand

[@simon-yt]

@@MrDIYca Thank you so much for your response. Can you tell me, if I have to solder the "voltage divider" or the "CAN termination resistor" if I want to use it in my Tesla model 3 from year 2022?

[@MrDIYca]

@@simon-yt No, no need. The car already has the termination, and the divider is only necessary if you want to monitor the low voltage battery.

[@simon-yt]

@@MrDIYca thank you so much for your help. I tried it out (flashed can reciever and display) and it worked instantly. Super easy! When I press a button on the display, I can connect to a wifi, but it is password secured. What is the right password here? Thanks a lot

[@MrDIYca]

@@simon-yt Awesome! great to hear. The hotspot is there for OTA. The password is: mrdiy.ca

[@SanskaariOG]

Do you have a DBC for the Model Y?

[@MrDIYca]

I believe you can just use the Model 3 one - not 100% sure though!

[@redplayzgamzalt2460]

Is it possible to have a bar to show Energy Usage/Regen? Maybe have the exact Kwh being used/generated?

[@MrDIYca]

yes, but I kept it simple

[@WesYarber]

Have you thought about messing with sending CAN messages to enable hands free auto-steer?

[@MrDIYca]

I built a gadget that controls the volume, and it might be used for this purpose. I'll test to see if it works

Just be careful.. Safety requirements have reasons… would you make a by pass for seatbelts? Just because you can does not mean do.

@@MrDIYca thank you, I should have also mentioned if the option of creating a negative & reversed image on the display is possible for anyone wanting to reflect onto the windscreen?

[@TwanJaarsveld1]

I have a rear screen that runs Android and taps into the canbus of the car, could this be used instead of the can adapter ?

Probably not

not sure

[@oxzymot]

I tried flashing the display with your online flasher but someting is not ok, flash seems to be ok but after rebooting the display it seems to be just an OTA updater. Did I miss something?

[@MrDIYca]

OTA activates when the button on the screen is pressed. It seems like something might be unintentionally pressing that button.

[@oxzymot]

@@MrDIYca, thanks for you answwer. Yes, that was me, I pressed the button because on boot there is nothing in the screen, just blank, it this normal until the CAN bridge send any data? I also tried the source code link and is seems to be dead

[@MrDIYca]

That's correct, you won't see anything until the bridge begins transmitting data. It's a members-only link, but unfortunately, KZbin just displays a generic 'not found' error page if you are not a member of the channel.
