Elders and Betters!(posted 8244 days ago)I am nearsighted, my eyes never did work well in the dark, they are on their seventh decade, and spotting the sweep second hand on my watch is hit-or-miss. In order to keep paper in the developer for the requisite two minutes I need:
One small mechanical or battery powered timer.
Ideally the timer would emit a gentle "ding" or buzz at the end of two minutes. I cannot use my Gralab timer, which is hard-wired into a cold-light enlarger. I want something a tad more accurate than the classical egg-timer.
Any ideas on who could supply one of the above?
Many thanks!
