Two of the 3″ x 18″ actuators on the way. Will need to figure out how to attach them over this next week.
We are exchanging the M1d for an M2d siting safety concerns with the unit if the signal voltage was to drop (computer lost power or died, cable unplugged or breaks).
Decision made not to upgrade to the higher sensitivity accelerometer because the vibration induced by the compressor is slightly higher than the 0.002 G noise we get from the current model.
Speaking of noise, I wrote an algorithm to simulate the noise and then wrote a deadband algorithm for the output. The idea is to save wear and tear on the M2d and to prevent filtered, dried air from being wasted.
