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.
Top down view of this test cut seen on the Leica. This is the ground plane one layer below the QFN thermal pad. I'm not sure why the board designer put five big vias in the pad for heatsinking and then added reliefs to the plane, but... you'd have to ask them why the plane was on the wrong net first (one of the reasons this board was scrapped years ago lol).
But hey, good practice.
What do y'all think, is this video quality good enough for me to livestream a reworkctf playthrough?
Obviously many of the challenges won't use the mill and if I'm recording with the Leica the video quality will be more like what you see in the still image above.
But the mill is something I have previously not been able to film on at all so I figure anything is progress.
