mavroOBD – My OpenSource project designed to “hack” your vehicle

Today I’m announcing my next project, mavroOBD.  It’s an open source Arduino compatible OBD/Can-Bus module.  The goal behind this is to provide an easy way for people to interact with their vehicles.   Not sure where this will lead but I’ve been wanting to get into the “car hacking” space for a while.  I’ve already sourced an OBD port module and designed two boards (power and mainboard).    This is an open source project and is available here on Github.

The idea is to be able to enhance my vehicles capabilities — since they don’t provide us a way to do this via configuration screens in the vehicle — one thing that drives me crazy is in my vehicle, I have to press a button for my front parking sensors to be active (if I haven’t been in reverse first).  This is annoying when pulling into a space.   My first task will be to emulate the parking sensor button when traveling less than 10mph.

The first step is to sniff the OBD port Can-Bus traffic to see if I have access to the system via the OBD port.  Depending on the manufacture some of the “internal”, non-diagnostic features are on a low or medium speed Can-Bus.   I’m still learning so if anyone has more knowledge and wants to share, please post a comment or join my efforts.  More to come… components will be here soon and I will be posting again when I get the boards populated and I can access the high-speed can bus network of my vehicle.

(This is part of a multi-part series on building a FPV mini 240mm quadcopter)

We're almost done with all the parts needed to build my FPV -- just a few more before we start assembling the quad.  I ordered the Fat Shark Dominator V2 Goggles and those have arrived. I needed some 5.8GHz antennas for the receiver on the googles and for the transmitter.   There are lots of videos on YouTube that instruct you on how to build your own but I wanted to buy a set ready made.

We're almost done with all the parts needed to build my FPV -- just a few more before we start building the quad.  I ordered the Fat Shark Dominator V2 Goggles that will be used to fly the FPV.   The video from the FPV camera will be wirelessly sent from the transmitter with OSD telemetry data superimposed to these goggles.  Can't wait to experience it!

DIY: Building a Mini Quadcopter Part 10 – ImmersionRC 600mW Video Transmitter

Since I'm building an FPV (first person view) quadcopter it relies on transmitting video from the FPV camera from Part 5 (I'll be covering the goggles and antennas in a future post).

DIY: Building a Mini Quadcopter Part 9 – 12 Amp PRO RapidESC (SimonK)

To power the SunnySky X2204S 2300kv Motors you need an ESC (Electronic Speed Controller).   For this,  I've selected the next generation speed controller from Quadrysteria.  They state the manufacturer of this ESC is the same as the one that made the popular BlueSeries and features newer, higher-quality MOSFETs that run cooler and offer higher peak current -- apparently these ESC are so fast that you can double your PI gains.
