Home-Made, Low Cost (Cheap) UV Exposure Unit

[bulldurham]

I recently rearranged a storage shed to accommodate a small Alt Processes darkroom for processing and a UV exposure for my negative work. Attached are images of my darkroom and the UV unit. I built the unit for around $70 because I was able to find a Gra-Lab timer for &$10.00.

I've also attached a cyanotype print (from a digital negative) I did this afternoon at 7 minutes, 30 seconds.

Light blue? Did you post process the color? What's the black object on the yellow box? What is it's function. Why is there two wires connecting with the timer?

It's a cyanotype...it will be varying shades of blue. The black "thing" is the UV Exposure lamp. One wire plugs the UV unit into the timer and the other gets electricity to the timer.
