Topic: Interested In Generating Roast Curves (7 msgs / 184 lines)
1) From: Jeremy DeFranco
     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.

Hey, thanks Matt for your advice. 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?

     Onset is out. Their software is not designed to perform many functions
in real time. 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)
