I just finished a program for a LabJack controller and was wondering if anyone is interested in it for a modest donation (~$20). It only works with a LabJack DAQ and you currently have to wire your Inputs/Outputs to my specifications, which shouldn't be a big deal. If you're interested, let me know.
The program has a hop addition schedule, but it doesn't currently read from XML. You have to manually enter the info, which takes all of about 10 seconds.
