I show how to collect detailed CAN bus data from a Tesla Model S, and display it in the car's own web browser!

Get node.js installed on the RPi: http://thisdavej.com/beginners-guide-to-installing-node-js-on-a-raspberry-pi/

I used socket.io, which is a module that installs into node.js: https://www.npmjs.com/package/socket.io

Basic sequence to setup the server on the Pi:

sudo ip link set can0 type can bitrate 500000 listen-only on

sudo ip link set can0 up

candump -cae can0,0:0,#FFFFFFFF

candump -cae can0,0:0,#FFFFFFFF | grep 106 | awk -Winteractive '{ print $10}' | node app.js

I will post the node.js code on my blog:
