Filtering Sensor Data with a Kalman Filter

Some days ago I wrote about noise with a LIS302DL accelerometer. There is obviously something wrong with my hardware. But before I get a new version out I need to implement some software filtering. After some unsuccessful results with low pass filters I choose the Kalman Filter. The Kalman Filter involves an awful lot of [...]

As you probably know, I really like I2C sensors and especially the LIS302DL. But adding this accelerometer to your circuit is not as straight forward as I thought. But in the end I got it quite right. It all started out with a 0.1µF ceramic capacitor. For good measure I put a ferrite bead in [...]

Ages ago I bought an LIS302DL from Sparkfun. One of the old (little bit) messed up ones, but still 3 axis accelerometer with I2C output. No external parts. No pain. Fine! Before I go in any further investigation. I need to get it up & running with my arduino (actually an boarduino – but who [...]

Playing around with gravity: A basic piece exploring interaction with gravity. It is (again) half a ping pong ball. On the rim there is a red dot, which always stays up. You can turn it as you want – the red dot will go up again. Video after the click.
