==Compass sensors== HMC5843 - I think this one might be the best, if somebody knows how to do surface mount. It does 3-axis magnetometry which should avoid the requirement that the chip be parallel to the plane of the earth (I think it also uses an accelerometer in this process). Communicates via I2C. $20 at [http://parts.digikey.com/1/parts/1599656-sensor-magnetic-3-axis-20-lcc-hmc5843.html digikey]. Lots of information about it [http://dkc1.digikey.com/us/en/tod/Honeywell/HMC5843_NoAudio/HMC5843_NoAudio.html here] (looks like no accelerometer). That it needs a resistor and two capacitors might bring the real final the price up. Glitzo demo video: http://www.youtube.com/watch?v=T85Af1o_YAs&feature=channel_page The one Skory has is the Hitachi HM55B. $30 at [http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/ProductID/98/List/1/Default.aspx Parallax] Big pro: already mounted. Big con: only 2-axis. Medium con (maybe): not I2C, but, the code to read it with an Arduino is straight-forward and [http://www.arduino.cc/playground/Main/HM55B already exists]. Mar 16 2009 by Lamont Lucas: I ordered the Honeywell HMC1052L breakout board and sensor from sparkfun. (with board, $15, just the leadless 14 pin QFN package chip is $9). It should be in my hot little hands by thursday so I hope to have it working by sunday. It's a neat two-axis sensor, and the output is two analog voltages for Mar 16 2009 by Mikolaj Habryn: That looks like an ideal choice - might well be pin compatible with existing breakout boards from sparkfun for the 2-axis ones, too. Soldering LCCs might be a problem, though - simple SMD isn't too bad, but with these, there's no way to inspect the joints. I guess we can try it and see - I think I've tried to do one of these with a hot air Possible DIP format 3-axis option from sparkfun ($59): http://www.sparkfun.com/commerce/product_info.php?products_id=244 nice write up on using it with arduino / processing at NYU ITP: http://itp.nyu.edu/physcomp/sensors/Reports/ThreeAxisMag2 not so nice forum post at sparkfun: http://forum.sparkfun.com/viewtopic.php?t=9541&postdays=0&postorder=asc&highlight=micromag&start=15
