Magnetic servo clutches from DAGU

After years of being frusatrated by stripped gears in my servos I have finally done something about it. DAGU is now producing servo clutches to suit 8g and 9g miniature servos.

Unlike normal servo savers, Dagu servo clutches can be continuously rotated without damage to the clutch or the servo. They look like a servo horn but are a few millimeters thicker. They can be configured for both standard and continuous rotation servos. Here are some common configurations:

Homebrew tilt compensation?

Honeywell's datasheet on the HMC6343 compass states that tilt compensation is made using data from a built-in three axis accelerometer. I thought that a cheaper three-axis magnetometer- accelerometer combination is much more reasonable for small scale projects, so my question is: What kind of calculations do I need to perform to get a decent degree of accuracy?


8$ compass

4 weeks ago i ordered the dc-ss503 magnetic sensor module with tilt compensation, and i'm now trying to interface it with arduino. so far i have obtained the 4 values from the i2c bus, but i can't understand how to actually get a heading from it. this is the datasheet i found, which i know is the right one: http://gongxue.cn/lixueyuan/UploadFiles_8285/201004/2010042114001679.pdf .

does anyone have any experience with this module and can possibly help me? thanks
