Behind the scenes at Applied Science: Why video? Camera gear. Shop tour.



Ask questions in the comments, and I'll answer as many as I can.

I show my video production process, answer questions about why I make videos, discuss camera gear, and do a quick shop tour.

MEMs oscillator sensitivity to helium (helium kills iPhones)



I tested the 32KHz MEMs oscillator used in some phones, and discovered that just a 2% helium environment will cause the oscillator to fail.  I also do a teardown of the MEMs device, and inspect it under the electron microscope.
