CompnTemp Timer - Compensating Developing Timer software application
Version 1.0 of the CompnTemp Timer (CT) and it is now available from the website:

Features:
-Runs on Mac OS X or Windows machines
-Toggle between real and Comp Time
-Fahrenheit or Celsius temperature display
-User settable target temperature
-Keyboard or pull-down menu options to set time
-Optional remote USB 10-keypad start-stop & time input
-Programmable compensation curve
-User selected options (profiles) are savable
-Restorable default profiles
-Easily switch between profiles
-Count-down or Count-up timer modes
-Alert sound in countdown mode, at 00:05 sec. or user set interval
-Multiple print processing option in count-down mode

There is a review of the CT timer on pg 54 of the May/June 2008 View Camera Magazine: “A New Tool for the Darkroom” by Alan Ross and Eric Biggerstaff


The software costs $85 and the USB temperature probe can be purchased form Vernier Sci. for around $40. Details and more complete description of CT features and requirements are on the website. The manual and a demo version are downloadable for free from: http://curtpalm.com/Software.html. The demo version does not support use of the temperature probe, but one can set the temperature manually to demonstrate the compensation features.

You can see the timer in action at the Foto3 trade show.

Comments and/or suggestions are welcome.

I have released version 1.1 of the CompnTemp compensating developing timer.
new features in version 1.1:

- Celsius slidebars are fully functional, when one switches to Celsius Temp. display for the timer, the slidebars now switch also
- Metronome feature, a checkbox in the pref. panel turns on the metronome, which sounds a beep (the system alert sound) at a user set interval
- Zone VI film compensation parameters has been added to the default profiles.

There are new three default compensation parameters. Zone VI paper, Zone VI film and Ilford film. A graph showing temperature vs time response for all three default settings is in the version 1.1 manual.
The CompnTemp Demo version 1.1 is available for free download from the website.
