The Tesla Model 3 and Model Y are popular electric vehicles that dispense with some of the usual provisions you’d expect in a typical car. Namely, there’s no dash cluster in front of the driver; instead, all information is solely displayed on the center console screen. [Nick Nguyen] wasn’t a fan of this setup, and decided to hack together a dash cluster of his own.
The CANdash works in a simple fashion, snooping the Tesla’s CAN bus for all the information relevant to the vehicle’s operation. It’s capable of displaying everything from speed to the remaining range in the battery, while also allowing the user to keep an eye on things like coolant temperatures and whether the Tesla Autopilot system is currently available.
The build relies on a CANserver, an ESP32-based device specifically built for hooking up to the CAN bus on Tesla vehicles and sharing the data externally. The data can then be piped wirelessly to an Android phone running CANdash to display all the desired information. With the help of an aftermarket dash clip or a 3D printed custom mount, the phone can then be placed behind the steering wheel to display data in the usual location.
It’s a simple, straightforward hack that gives Tesla owners a useful feature that they’re otherwise missing from the factory. The US automakers cars are proving to be fertile ground for hackers and DIYers, with one man recently saving thousands on a battery swap with a simple mod. Video after the break.
