Gyros/Accelerometers? Compass?

[kresty]

Savage said he'd post something, but I ended up picking up these: MPU-6050 Gyros - 5 of them for $12
http://www.banggood.com/5Pcs-6DOF-MPU-60...59259.html
and these HMC5883L compass sensor, 5 for $6.

So 5 for the price of 2 of the other things (~$10 each), miss the pressure, but I'm not flying so probably don't need that. And I figure I don't need the compass on both the head and the body, so I'll have spares for other projects or if I fry them as I've done to other boards. Also maybe w/o pressure it'll use less power, though that's probably negligible and a wash.
