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.

Laser diode self-mixing: Range-finding and sub-micron vibration measurement

A plain laser diode can easily measure sub-micron vibrations from centimeters away by self-mixing interferometry!  I also show how this technique can be used for range-finding.

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.

Dry water and Burning ice: all about gas hydrates

Two unusual materials with unusual names.  I show how to make "dry" water and propane gas hydrate, which looks like ice and is flammable.

Make plastic printed circuits with a standard laser cutter

I developed a new chemical process to make double-sided PCBs with a laser cutter, and some common chemicals.  This is intended to be used on SLA 3D-printed parts, but may work on many materials.
