Posture-based game controller

I quickly built a game controller to test the idea of generated game inputs from the player's posture (shift in center-of-gravity). This controller is built from a digital bathroom scale and an XBox 360 controller. I used an opamp to convert the bathroom scale's sensor input to a thumbstick input. I also added a mouse to capture yaw.

Intro to sputtering (process to create clear, conductive coatings)

I have finally been successful in creating a conductive, clear layer of indium-tin oxide on a microscope slide. In this video, I show the process and explain how sputtering works.

Clear flexible printed circuits - first success

I'm making flexible printed circuits with my vacuum deposition machine. In this video, I show my first successful active circuit built with copper deposited onto laser printer transparency sheets. My ultimate goal is to make thin film transistors and OLEDs that are deposited onto the substrate.

Intro to heat treatment of steel (hardening and tempering)

I try to bridge the gap between in-depth theoretical explanations of heat treatment, and rote tradition.

Detectron DG-2 geiger counter teardown and testing

I take apart a Detectron DG-2 geiger counter, and discover the circuit still works after 60 years!
