Digital Projector Project

I have decided, over my Easter break, that I am going build a Digital Projector in 10 easy steps (Just In Time for the World Cup and the last episode of 24!) You can track the progress on this page, photos should be added at a later date.

Step 1: Design

The Digital projector will consist of a MDF Box with a couple of lenses inside, a high power lamp and a LCD moniter. There will be a lens in the front of the box which will be able to move to adjust focus. Hopefully it will be able to project an 120 inch image onto my flat wall.

Step 2: Box Build

I made a simple box just the house the prototype, nothing really special 6 sides of MDF with a handle on the top for portabilty.

Step 3: Add Electronics

Again not alot was needed, two switches, a power connector and a big fan to get the heat of the lamp outside away from the LCD, all nicely on the left handside of the back. Still to be added is a grill for the fan and the temperature sensor.

Note: I had to add two more fans cause of the build up of heat :)
