Another entry in the Freetronics Instructables competition this week is this interesting personal "black box recorder" by member cgmalantonio. It uses an Arduino Mega board to interface with a GPS, accelerometer and magnetometer - and the relevant data is logged to an SD card. Furthermore the compass data and system status is illustrated using a LEDs which can be viewed on the side of the box as shown below:
It's a neat project which gives you the framework for all sorts of data logging applications, so for all the details on the black box project, visit the Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you're enjoying working with Arduino projects but find the Uno-sized boards somewhat constricting - it's time to move up to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
