I'm currently building the following system and hope to use it in the near future for 8x10 dev

1 infrared nightvision monocular
1 infrared LED light source
1 glass tray

The idea is to have the IR light source under the glass tray beaming up through the film while it's being dev'd. The infrared night vision scope can watch the development. You can find the scopes on ebay and the IR light sources at reasonable prices. I plan to post an article on it when it's up and running. The scope works great too, I am able to read very fine text on a page in total darkness at a 12inch distance. So the end result should be like deving film on a light table..
