Check Us Out on Kickstarter

Well it's official...we're now on Kickstarter.  As many of you know I've been working on my open source tracking device for quite some time now.  I'm getting close to finishing off the prototype and decided to look for some funding to help bring the project to the next level.  For those of you that don't know what Kickstarter is, it's basically a way for people to solicit funds using a technique known as crowd funding

Just a reminder, I still don't have a name for the board so if you want a chance to win a FREE one check out the rules here and submit your entry to This email address is being protected from spambots.

So please check out our listing as I think you'll see some fun and exciting rewards available to those who would like to contribute.


Tracking Device Update


I finished assembling the first revision of the tracking device.  Unfortunately there was a slight problem with the footprint for the BMA180 so the accelerometer portion of the board is non functional.  I've also come to the realization that I'm no longer going to use 402 SMD components for future designs. As much as I love the challenge of trying to place these tiny little parts on a board I think I'm going to move to 603 and up from now on.

Step by Step Guide on Making an I2C Slave Device with an Arduino

There are lots of examples on the internet on how to program an Arduino as an I2C master to communicate with I2C slave devices.  There are, however, very few examples out there on how to program your Arduino as a slave device.  One of the best sites I’ve seen for documentation on I2C slave programming is over at Nick Gammon’s blog

Well I thought I would take it a step further and put together a step by step guide showing you a real life example of how to make an I2C slave device using an Arduino. I did a lot of research while making my I2C GPS Shield and thought I’d pass along some of what I learned.
