mavroOBD PART 2 – Arduino 328P ODB CanBus Hacking


… continued from part I.

It’s been a while since I last posted an update on the mavroOBD project.  After a few (3) board revisions, I’m happy to report that I’ve successfully miniaturized the Arduino UNO (ATMega328P based AVR) and SeeedStudio CANBus shield into a compact OBD module form factor.   Next, I will begin the coding portion and will post updates as that happens.  Feel free to post a comment if you are interested in helping out with this project.

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.

Review: Outdoor Weatherproof SunbriteTV 46″ Signature Series TV

I’m working on the new Holiday Gift Guides and had a 46″ SunbriteTV LCD TV from their Signature Series line in for review.  Thought I’d do a quick video review for the readers of Mavromatic.  It’s a pretty neat TV especially that you can permanently keep it installed outdoors as it’s completely weatherproof.   Watch the video above and let me know what you think of it in the comments below.  Please subscribe to our YouTube channel, it helps push our content into more YouTube suggestions.

Getting Continuity / Hand-off working on a MacBook Pro Late 2011 Model

Loving Yosemite, Apple’s latest version of OS X but you cannot get Continuity / Hand-off working with your iOS8 device and computer?  Chances are you don’t have a computer that has the required Bluetooth Low Energy 4.0 chipset — needs to be a model year 2012 or later.  No worries, you can swap out the Bluetooth module pretty easy as Apple uses the same modules on different computers. Check out my latest video on YouTube that shows how to get your Late 2011 Model MacBook Pro 15″ (13″ should be similar) working with Continuity.

You’ll need to order the correct Bluetooth module for your MacBook Pro — be certain that is has the “CAX” marking, not just AX.  I used the following one from eBay — New MacBook Pro A1278 A1286 A1297 Unibody AirPort Extreme Card for 2011-2012.

For further assembly instructions check out the great guides on ifixit.

You can download the patch script from here:
For more detailed script instructions (thanks Lem3ssie!) check out this forum:

Leave any questions on YouTube or in the comments.

UPDATE: If you updated to 10.10.1 you will need to reapply the script or download the Continuity Activation Tool and it will do it all for you.
