Introduction: Project'hour : Hack a LCD Clock Into a Projector Slide
How to hack a LCD clock to project time through a slide projector.
For this Instructable, I chose the Photo Instructable because it would have made no sense to describe steps that wont be the same for you as you probably won't have the same LCD.
I'll do my best so you can understand how I did and so you can do something similar with whatever you'll find for lcd.
The goal is to include a transparent lcd in a slide frame.
Videos of the result.
A very interesting point is that the plastic frame changes the polarization of the light, which can be seen by adding a polarized filter, so that the plastic window is between this filter and the lcd screen.
About the contest.
Originally, I wanted to hack a clock mechanism by adding motors that would shift figures slowly to display time.
It would have been composed of 3 strips of transparent overhead projector sheet. ( H : M M )
Those sheets would unroll from the top, shift in the projector and roll in the bottom.
The problem was I couldn't master the signal out the quartz movement ( the small stepper motor) be cause I have no serious equipment to monitor it.
I tried to amplify the signal with transistors but I had too many noise and no usable signal.
So I thought about another way, the LCD.
But I still want to realise my first idea, and some equipment would be welcome!
