Tongue mouse: Cursor control with your mouth!

I wanted to test the idea of using the tongue to control a computer. The most obvious way would be to map x/y coordinates in a Windows-style UI with tongue movements constrained to a plane. This doesn't work terribly well, as even though the tongue has fine motor control, it's very difficult to smoothy achieve the 2D movements needed to operate a system that has been developed around a classic mouse. I think there is possible applications for swipe interfaces, carousel menus, yes/no input, etc.

Patterning aluminum with the photoresist "lift-off" method

I show how the photoresist "lift-off" method works to pattern thin films as they are deposited. In this case, I patterned aluminum on a microscope slide.


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.
