This cheap indicator stand doesn't stick that well to the table through the mat, but it's better than what I had before. Had to shim the camera with some electrical tape to make it fit.
The setup is definitely getting as cramped as a FIB chamber with the spindle, camera, optical scope, light, compressed gas spray, and suction all vying for space around the workpiece
Second test recording using the indicator mount. Still some vibration but it's less. You can definitely see a lot better when I stop the spindle, but swarf usually blocks the view a bit during the cut anyway so I think this is probably good enough for livestreaming purposes? I'll be switching to the other microscope for high mag imaging and soldering etc anyway.
I need to move the mic even closer to my mouth or make a conscious effort to speak up, a lot, to be intelligible over the background noise.
This is also postprocessed in Audacity, the raw recording has more noise but might be a bit clearer actually? I'll need to experiment a bit.
@azonenberg Not bad for what it is.
For the audio you might try some EQ to take out some of the background noise and to boost your voice range, there seems to be enough difference in freq ranges where it might help.
Getting the mic as close to your mouth as possible always help too, with maybe a tad of compression so with the mill on and louder talking it can keep the channel from clipping with any vocal emphasis.
For the video, I dunno, maybe more light and from a different angle? Some video software has image stabilization, but the vibration frequencies here may be too high, especially with a rolling shutter. Maybe a more stable camera holder? I'm sure the tight arrangement creates all sorts of issues.
