Here's the finished document camera. It can take 10 mega pixel photos of an open book about 5 seconds a page allowing for the user to turn the page.
LED lights are bright, white, and very importantly cool.
Plexi lids keep docs flat when needed, but can be removed when desired for really fast page changing.
Height is perfect for easy viewing of camera display, and still convient to work the document.
Camera and lights do double duty, so the total project cost is less than $50
