I'm on the road for a few weeks and to pass the time I want to develop some film. I packed a changing bag, Paterson tank, and some chemicals; but no timer (Gralab is just too big). Are there any good timer programs for this out there? Google search didn't yield much except multiple downloads for the "Pachyderm" timer shareware which appears to be a computer interfaced enlarger timer more than a film timer. I could use my cellphone countdown timer but that's kind of a pain to reset every step, especially with chemicals all over my gloves.
