Years ago I watched an Ansel Adams video, and he mentioned that he used a metronome as a timer. Anyone here using one? My darkroom is just about complete, and was wondering whether to spring for a cheap Time O Lite timer or something like that, or buy an even cheaper metronome and buy some film w/ the difference. Actually, the little alarm clock that I use for a film developing timer is pretty audible, but the idea of using a metronome appeals to me. You can buy the small electronic metronomes that musicians use for $5, but I think I'd want a "real" one.
