Subject: Roast logging. How does the Artisan connect to my Poppery
 

After some thinking, I'm going to put off the idea of upgrading my roaster for a while. I'm getting awesome results (for me) with my current setup (poppery 1, router speed controller, fan dimmer). I would really like to be able to log my roasts on my computer. I downloaded Artisan to my Mac. What in the world do I need to connect to my poppery now? I read a great step by step thing someone wrote but this was with hooking up a PID also and it confused the heck out of me. Can anyone help me out?

Plan on 2 temperature probes to log: Environment Temp ET, and Bean Temp BT.  ET is installed in the bottom of the Popper somewhere to measure the heated air before it hits the bean mass. ET is the 'oven temperature' that you are actually controlling with your router, PID, or Variac. The BT is the 'effect' of ET on the beans over time. ET is at least as important as BT monitor for profile control and in getting consistent and repeatable profile control.

You will find the ET easy to control in 'real time' on a poppery. Adjustments to heater power take effect within a few seconds; there is very little thermal lag in the system. It is possible to do a 'linked temperature' profile where ET 'setpoint' follows BT; BT Rate-of-Rise is dependent on the temperature difference between ET and BT.

I did see that guys setup that you posted Butterfinger. Trying to understand what he did made my head want to explode.

Frost- I guess what I'm really not understanding is the physical connection to the computer or I pad. Say I were to buy 2 thermocouples. What do they plug into? I'm really just interested in logging my roasts more efficiently and more accurate  than with a pen paper and my Fluke meter TC. I'm only monitoring BT now.

You need some sort of interface between the thermocouple and your computer.  

Artisan is designed to work with a bunch of them.  One really popular option is to plug the probes into a stand-alone data logging thermometer with USB output, and plug the thermometer (via USB, natch) into the computer.  

The two I've seen used most often are the Amprobe TMD 56 and Omega HH806AU (I have both).  They function more or less identically, but the Amprobe is quite a bit less expensive and the Omega more rugged.

Another option, becoming increasingly popular since last year's interruption in TC-4 supply, is the Phidget 1048_0 thermometer board.  The Phidget has neither a built in display nor stand alone data logging capacity -- but you don't need them.  For another couple of hundred, Phidget will sell you an SBC board and USB -> WiFi adapter allowing you to go wireless with Artisan if you want.

It's all a little daunting til you get it worked out, then it seems ridiculously simple.

If I were starting from scratch, and didn't need stand alone thermometers for other purposes (like barbecue), I'd probably go Phidget because it's a tidier installation.

Thank you so much Rich. It all makes a bit more sense now. I've been looking into the Amprobe, Omega, and the Phidget for the last hour or so and I think the Amprobe might be it for me. I can't spend a fortune on this thing right now and it sounds pretty simple to get up and running on my Macbook. You BBQ Rich?  I have a Weber Bullet and Guru controller. I used to be crazy about it a couple years ago. Then my wife and I bought a house that needed major renovations (its pretty much consumed my life lol)  and I just haven't made any time for BBQing.

Yes.  Not that equipment matters, but we have a 4' "Santa Maria" style cooker for grilling, and (with the lid on) for hot or cold smoking; and a Fat Boy we use for low and slow.

Then my wife and I bought a house that needed major renovations (its pretty much consumed my life lol)  and I just haven't made any time for BBQing.

Know how that works.  Sometimes it's not just "too busy," either.  It's just the normal ebb and flow of interest.  But when push comes to shove and the weather gets hot, it's so much nicer to cook outside.

Goldensncoffee, I'd be interested in seeing some of your profiles for ethiopians.  I have a modified popper with independent heat and fan control.  I'm trying to get a bright cup with an Ethiopian Sidamo.  What does your ramp up to FC look like and when do you hit FC?  What is your typical drop time?

I'm not sure I'm the right person you want to ask as I'm very new to roasting :-) I've only roasted a couple Ethiopians. I will say they very good...I've only had one pro-roasted Kaffa before so I don't have a lot to compare my roasts to. Right now I do (try to do) very basic 4-4-4 profiles or close to that. Most of my roasts end around 12-13 mins. I will vary finish temps and cup the roasts and compare what I'm tasting in a lighter, medium, darker roast (never beyond first signs of 2C). One piece of advise I can give is to make sure your roaster is preheated. The first roast is always tough for me to try and follow a profile.
So what kind of controls do you have on your popper? How are you currently roasting your Ethiopians? Is there something your not liking about your current roasts?

I have not be terribly impressed with my results.  I use a Gene Cafe mostly and can't get great roasts out of that machine either.  I like the popper because of control but batches are too small.  I drink a lot of counter culture coffee at a local coffee shop and now I'm spoiled.  I want results that taste like that but they elude me!
