Lightmeter of my sisters old MINOLTA SLR srt101b! Was hard to get by the proper photo-resistors that could handle light levels as low as f1.7@1/30, but managed to get some circuits going on that fix it. Maybe I will do some tutorial on how to fix ANY battery powered light meters.

A few weeks ago tunned my Yashica Mat 124g. Lightmeter works great and the shutter/aperture rings are now smooth! Also thinking of a tutorial for it, since seems to be a popular camera with lots of small easy to fix problems.
