So it’s 100% fat then?

Seriously! I’m not the only one who’s had this problem!

i actually WANT to help customers and do a great job because i take jobs seriously
none of your current employees are even trying
are you really sure that i’m unqualified??
I generally (there are exceptions) prefer to hire people without prior barista experience. That way I don’t have to get them to un-learn all the wrong stuff their previous trainer taught them in addition to training them to do things right.

Anonymous asked: hey neal, been wanting to set up a logging system for my diedrich ir-3. saw several of your videos and am looking forward to using typica. basically all of my questions are in this unanswered thread on coffeeforums/roasters where should i add thermocouples, di-145 support working? and is it worth adding 2 thermos instead of using the existing one. thanks! brian
I’m not sure what thread you’re referring to (is tumblr still not allowing links in asks?) but if I miss something and you want to do a follow up, shoot me an email.
DI-145 support: Working in the development branch on github, I’m using this myself now, will be in 1.6 (real soon now) with in-program configuration and channel calibration. Currently that support is Windows only. Should work with everything from XP through 8. Want to get it going on Mac/Linux as well but that won’t be done for the 1.6 release. I intend to put together a video before this goes out that covers how I have my IR-1 set up with that hardware which you might find informative.
Thermocouple placement: You should already have one placed appropriately for bean temperature and if you’re asking about the DI-145 I’m guessing you intend to just use the port on the roaster. That’s what I would recommend. On an IR-3, particularly now that Typica supports rate of temperature change data I probably would not bother adding the second thermocouple, but if you did the best place would be near the top of the drum, central, far enough away from the edge that moving parts aren’t going to bang into it but close enough to it that it won’t be covered in coffee beans except perhaps as the batch is first falling into the drum. Note that if you want a secondary thermocouple logged you’ll need either another data acquisition device to hook that into or another signal conditioner to amplify and linearize the signal if you want to hook it into an unused channel on the DI-145. To install that you’ll also want access to a drill press, an appropriately sized cobalt drill bit, and a tap wrench with tap appropriate for the threads on your mounting hardware.
I really need to do something better with data series color selection.
The timing on introducing the rate of temperature change monitoring feature in Typica’s development branch was good. New coffees recently arrived so these have this information in their target profiles. I’m saving new target profiles for the rest of the coffees as I get to them and most of those now also have that data (I don’t want to auto-generate the data). Now that these new profiles are turning up and I’m using the extra information to better match roast profiles I can say that I’ll recommend turning this feature on. Note in particular the slow section at first crack. This was really easy to maintain a match on and around and combined with the profile translation feature (3 seconds in this case) I expect our already low inter-batch variation on QA metrics to get even lower. The use is similar to using air temperature monitoring to better gauge control adjustments but easier since it nicely abstracts out differences in batch size and retained heat. Thanks all who requested the feature. It’s more useful than I expected.
I still have a few other areas where I want to polish things a bit more before the 1.6 release, but that should be happening very soon. I’m also hoping that I’ll be able to get some time in to assemble a couple videos, in particular one going over how I have all of the new stuff set up at the lab roaster, but there again I’m not going to hold the release up for something like that.
Finally got my back log queued.
