New tilt-compensated compass sensor

Sparkfun has released a lovely (if expensive) bit of silicon: a tilt-compensated magnetometer.



"The HMC6343 has three axis of magneto, three axis of accelerometer, and a PIC core running all the calculations. What you get is a compass heading over I2C that stays the same… Continue

Stanford quadcopters rock!

We've enjoyed watching the development of Stanford's STARMAC II quadcopters, and this video does a good job of showing why: the 6 vehicles are light, incredibly accurate in both GPS and ultrasonic position sensing, and…
