I was given a Yashica Mat-124G camera and you cannot get batteries for the light meter, so I decided to make one. I already had the analog meter and the small box, so the two were a natural fit. I also used Adobe Illustrator to make a new paper template and scale for the meter. This needs some work and I realize this is not actual lux levels. The trick here is to come up with a scale useful to the camera I will be using it with.
Nice use of the Adafruit Perma-Proto boards!
