Zitron, If you want to help me put together a board ill Order 2 and send you one for free...
I thought about making an arduino shield, but the i would prefer to have it as small as possible and just run a wire since its going to be on top of your head or glasses.
We can use the LIS302DL - $12.95 sparkfun
and the LISY300AL Single axis Gyro - $11.95 sparkfun
that lisy300al should give you about 100x better capabilities of controlling drift.
