For a fun and interesting project suitable for beginners, or a different gift for the holiday season consider making a random decision maker as documented by Instructables user "dmmMaster". Based on the concept of the novelty eight balls from days gone by, their iDress device detects movement the help of an accelerometer and returns a pre-programmed wardrobe choice based on the returned values. A quick demonstration is show in the following video:
However if you're happy with your own fashion choices, the device can be modified to display any sort of random data - and could be used as one or more die, a classic fortune teller, or as a chore decider. Many options to consider, so get started from the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking to recreate such a project, a good start would be with the AM3X accelerometer module:
This tiny 3-axis accelerometer module can operate in either +/-1.5 g or +/-6 g ranges, giving your project the ability to tell which way is up. Ideal for robotics projects, tilt sensors, vehicle data loggers, and whatever else you can dream up. For more information and to order, click here.
