The Backstory

I recently purchased a 2013 model year boat and in style of Mavromatic, I wanted to “hack/mod” the onboard electronics ASAP.   The previous owner had installed a Lowrance HDS 7 Gen 3 GPS/Chartplotter and added a NMEA 2000 backbone to use a Lowrance EP-60R fuel flow sensor (that I later found was clogged, a simple back-flush blow of compressed air fixed it).

mavroOBD PART 2 – Arduino 328P ODB CanBus Hacking

mavroOBD-rev3

… 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.

DIY: Building a Mini (220mm) Quadcopter Part 3 – Transmitter & FrSky D4R-II Receiver

(This is part of a multi-part series on building a FPV mini 220mm quadcopter)

These next parts aren't really that exciting but much needed for controlling the quadcopter.  I already have a Futaba 9C controller that features a neat little module system.    So I just needed to purchase a FrSky Transmitter Module that works with my Futaba controller -- the FrSky FF-1 2.4Ghz Combo Pack for Futaba w/ Module & RX), it's only $39 for the kit.

Tag-Connect: The ICP Connector That Saves PCB Space & Cost Less

April 21, 2014 3 Comments
There are a lot of little details you need to think about when taking a project from PoC (proof-of-concept) to production. Most projects today have some form of onboard microprocessor and require you to flash your custom bootloader and/or program code onto it at some point. There are many ways this can be accomplished but the most common method is using an ICP (in-circuit programmer) connected to a 6-pin ICP header somewhere on the PCB. Tags: , , , , , , ,
