Welcome
After weeks of trial and error (and more error!) I'm still having problems getting my Drosophila flight-simulator to record without noise. Even with a 300kg heavily damped table, the mechanical trasnducer (torque-compensator) is still showing noise at about 20 times the tolerable level. See the extended news body for pictures.Interestingly, that's the same setup (actually, even with more weight and damping) that worked just fine during my PhD thesis. Apparently, Berlin vibrates more than Würzburg
Here some pictures of the setup:
with the base stone-slab on foam:
the damping springs and rubber innertubes:
and the heavy stone-mounted arm with weights:
And this is the amount of noise I still get with this setup (the line should be completely straight and not jagged):
The scale on the left is the appropriate one and is in mdyncm, which is 10-10Nm.
