Lighting

The original LED light was replaced with a larger LED array. To avoid glare, the array is mounted perpendicularly so the long side is parallel with the spine of the book.

Cameras

We use two Canon cameras connected with USB to a computer and remote-controlled with the gphoto2 library. The pictures are transferred to the computer as soon as they are taken, rather than stored on an SD card.

Trigger

The cameras are triggered by a button mounted next to the handle on the scanner. The button is connected to a circuit board from a USB keyboard, so it behaves like pressing the "enter" key on the computer.
