Hello Everyone! I'm interested in generating roast curves for my futur= e roasts. I noticed on SM website that Tom has used an Extech datalogger for some of his product tests. I know these can record data, which can later be uploaded to a computer, but does anyone know about generating a roast curve on a computer in real-time, during the roast session itself? I have also been confused about finding the proper cables and thermocouples, and adaptors etc. that one would use to connect to the computer. Does anyone have any suggestions as to what the best route would be if I really wanted to precicely data log my roasts in real-time? Also, if I want to upgrade to a Hottop roaster in the future, will there be a risk of melting the thermocoupler, that would not be such an issue in an iRoast or popper? Please keep in mind that I have no background in advanced computer tactics or datalogging, etc, but I am really willing to learn- So I might not understand technical language, but I still am interested in creating a worthy real-time with near any amount of leg work . Supposedly real-time computer generated roast curves are supposed to be the best way to monitor = a roast session- makes sense too. I'm ready to check this out. Thanks in advance for any guidance on this subject. In the meantime, I'll be enjoying this beautiful batch of blueberry Harar I roasted up yesterday. Happy Roasting!, Jeremy
Jeremy, There was a thread on this list recently about "USB Data Loggers" if you're interested in what some list memebers have to say about data loggers that's a good thread to check out. As for me: I use a PhidgetTemperatureSensor http://www.phidgetsusa.com/cat/viewproduct.asp?category&subcategoryA00&SKU51).If you use windows and have excel I've got a fugly little app http://coffee.menagerie.cc/templogger.xls)that "works" (sorry to anybody who tried to download it recently and got an error, I've fixed the folder permissions). There are more details in the last email of the "USB Data Loggers" thread. ~/Matt

I checked out the archives, and I checked out the Phidget and your home made software. I'll have to say that the setu= p you use looks pretty cool. I am looking for a more analytical real-time data-logging software, though, and I don't know how to program my own apps, so I did end up doing some lengthy searching on the net. The archives serve= d as an excellent starting ground. For anyone interested, I finally came up with a MadgeTech Thermocouple Data Logger at this link.The software that is ordered with this allows real-time data logging in graph format, along with options for graph-on-graph analysis and a slew of other analysis features, as well as the ability to load graphs into excel for final mod, if need be. The final setup looks to be around $250 after datalogger, usb, software, thermocouple, and replacement battery are ordered. I also checked out Onset hereand here (k-thermocouple)and found another company called Veriteq here with similar products. As of yet, I am waiting for reply emails from these folks to see if graph capability is possible in real time. I'll update the list when I hear back from them (hopefully soon). Anyway, now atleast I have a few options, and will probably purchase a setup in the next few weeks. The archives helped tremendously... Hope I provided even more options to any other list members interested as well. Happy Roasting, Jeremy
Forgot to mention, can also make any USB Data logger wireless! All u need i= s a wireless USB networking device. This one looks pretty cool! click here.I think you could probably buy a wireless USB adaptor, though at any place that sells computer accessories.... Wow, this is starting to get really interesting... Veritech sells software that can be installed in a PDA as well to accompany its data logger CHECK THIS OUT!Holy Shnikies! Only problem is I'm still waiting on a price quote from this company, along with info about whether the software enables real-time graphing. I'll definitely post the info when I get it! Who'd a thunk you could roast coffee from a 1000 feet away!
Matt - Does the Phidget sensor have memory store so that temps can be collected and then loaded to a computer later?

Veritech is out as well, with their datalogger weighing in at over $500, not including USB adapter and other miscellany. Looks like its MadgeTech all the way! Jeremy
Jeremy, Did you notice that the serial cable is an 'Active' cable. I expect you are planning to use a USB to SERIAL adapter to allow using the data logger with a USB hookup to your computer. According to the MadgeTech web site you have to use their cable instead of a normal serial cable. I think I would check with both the MadgeTech people and the USB adapter people to make sure you can get power thru the adapter to the active serial cable. Mike (just plain)
