Spark Fun Electronics is now carrying a rather interesting sensor:
It’s actually two sensors in one: a gyroscope and an accelerometer! From SparkFun, “This small PCB board incorporates the new IDG300 dual-axis gyroscope and Analog Devices triple axis accelerometer in a tight footprint.”
Personally, I think helps open new doors to a higher level of thinking for students, hobbyists, educators and researches. Dave thinks there’s no point on having any more than three degrees of freedom because you can determine angular velocity from the X, Y, and Z coordinates from calculations. Although he has a point, I have to argue that it is a lot more convenient to an end user to have all six right out of the box without having to perform additional calculations outside of the sensor to retrieve the other three. What do you think?
