RoastLogger
Introduction

Thank you for your interest in RoastLogger.  This program is copyright 2009-2012 Tom Coxon. (GreenBean at TMC http://www.toomuchcoffee.com ) and is distributed "as is".  No warranty of any kind is expressed or implied. 

Coffee enthusiasts may download and use this program free of charge.  See the License section of the help file for more information.

This roast logger can read, log and chart one or two temperature inputs simultaneously and in real time as the roast progresses.  Either or both temperature inputs can be read directly from selected multimeters, from a webcam image of a roasters display via optical character recognition (OCR),  from an Arduino or from a user supplied application reading users hardware.   

Any previously saved profile can be used as a template for the next roast.

Computer control of a Hottop  D, B or P

Would you like a computer controlled Hottop coffee roaster?  Hottop model D, B or P roasters can now be converted to a computer controlled roaster.  The conversion involves the installation of a TC4 system and a HT Roaster Interface Device (HTC or HTShield) and connecting everything up by plugging in standard Hottop control cables and a USB cable.

Randy Glass has produced an excellent and comprehensive user guide for the HT Roaster Interface Device and has updated the RoastLogger manual to include working with the HT Roaster Interface Device which can be viewed or downloaded from the link below.  Further information is available here.   Please review the disclaimer included in this link and ensure that you have the required skills before attempting the conversion.
