Supercritical CO2 extraction of cinnamon, coffee, and vanilla with dry ice

I built a small extraction chamber for processing materials with supercritical CO2.

Please refer to my previous videos for more information about supercritical co2:

Making patterned mirrors and ITO glass with a thermal evaporator

I've put enough work into my thermal evaporator project so that I can actually start using it to create thin films. For my first test, I make some aluminum mirrors on glass, and also coated glass with ITO (Indium Tin Oxide). The mirrors look nice, but the ITO was not conductive -- more research required.

Photomicrography (microphotography, macro), focus stacking

In this video, I show my setup for taking focus-stacked images with microscope objectives. I use a Lumix GH1, which is a micro 4/3 format camera, and a custom adapter that lets me interface the camera to a microscope body or directly to a microscope objective.
