    “I got it on video!” Actobotics fail video #1.

    Noise on this version SEN-10321. In case any of you have the same noise problem, Ill try to save you some time. I have encountered about 30 counts of noise on the accelerometer. Spent a lot of time trying to “fix” my i2c I/F software which is fine. Turns out there is a nasty ripple on the 3.3v at the i2c clock freq (400khz in my case). Added a 10uf electrolitic cap at the regulator output (parallel the existing), and it knocked the noise way down to just 2 or 3 LSB.

    Noise on old version SEN-10321. In case any of you have the same noise problem, Ill try to save you some time. I have encountered about 30 counts of noise on the accelerometer. Spent a lot of time trying to “fix” my i2c I/F software which is fine. Turns out there is a nasty ripple on the 3.3v at the i2c clock freq (400khz in my case). Added a tantalum cap at the regulator (parallel the existing), and it knocked the noise way down to just 2 or 3 LSB.
    Now to see why the magnetometer is wandering about.

    They are in there. The device names are ST-GYRO-PR and ST-GYRO-PY and the package name is ST-GYRO. Thanks Jim,

    It’s stated as “SFE Eagle Library has this part!”, but the latest version 11/03/09 does not have it. It is even listed as “New parts worth noting:” on the opencircuits site. Help, I’ve lost my footprint :^(

No public wish lists :(
