Trinocular microscope, various adapters and a DSLR camera with live view and HDMI output to a monitor. I record the video from the monitor screen with my phone. I'll try direct capture when I can get another HDMI cable. Not cheap or simple but the video quality is way better than those overpriced USB microscope cameras.

Yes, I have one of those usb ones and it's shit. I've got some basic but decent monocular microscopes, I might get a phone adaptor for one of those. Great videos, thanks for sharing.
I did some freehand recordings with my phone through the eyepiece and they were good. The hardest part was holding the phone in the right spot so I bet an a adapter would work well.
