I've finished my first custom DIY LCD, and describe the process in this video.

I've been exploring technology made possible by having clear, patterned electrodes on glass, and succeeded in making a working (barely) LCD. In this video, I explain types of liquid crystal molecules, and how they can be used to make an efficient display.

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.

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.
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.
