Support / Re: ThermaQ probe for popcorn maker?
« on: January 10, 2019, 04:24:54 PM »
Sounds cool!

Before getting my 1 Kilo drum roaster, I had a Quest. The Quest was pretty easy to mod for thermocouples. I think later models even shipped with mounts and dedicated holes.

On my current roaster, I didn't relish drilling through cast iron, so I sacrificed a screw mount (that was drilled all the way through the faceplate), and the TC hits the bean mass perfectly. (See attachment).

Sorry, I don't have any experience on newer sample roasters, just wanted you to be aware of this trick, in case it helps with the model you choose.

Hi Dave...welcome!

The only popcorn maker I've ever roasted on is a Whirley Pop, back in the day, so I can't speak from experience. But, I equipped that with a probe, and the basics are the same, whether its a popcorn maker or a large shop roaster. You want to get the probe in the center of the bean mass as much as possible. For a fluid style of roasting (assuming you're using the air popper version) that's more of a judgment call, and you'll end up measuring air temps as well, but with proper placement it will allow you accomplish the same results - repeatability.

The ThermaQ Blue accepts ANY style of K type thermocouple, and thermocouples CAN be bent AS LONG as you bend on a radius, i.e. no sharp corners. Think "U" shaped, not "L" shaped. Also stay away from the tip (where the junction is) at least 1/2". That being said, I'd take some measurements of the machine...maybe use pipe cleaners if you plan on bending it to help you get it right, and choose an 1/8" K type probe that hits your measurement plus some to go through the casing. You can get a wide array of sizes on Amazon...ranging from an inch or two through longer lengths.

Good luck!!

Roastmaster's data structure is a bit too complex for the usual iCloud sync. In lieu of that, I've provided a few different ways to quickly transfer data to and from other devices. The easiest is to open the drum door on the home screen and choose "Export Current Database". If your other device is awake and nearby, you should see it appear in the "Airdrop" section. Tap it to send it to that device, and choose "Overwrite" on the receiving device.

Hope this helps.

Hi Tim

Thanks for the links. I reached out to them this morning via email. I'll let you know what I hear back.

But, it does provide you the satisfaction of achieving a goal.

That has been the sole outcome of some of my machine modding and tweaking ventures. :) Still worth it in the end, I think!

Hi Tim

I was certain I had tried to contact them in the past, but can't find any record of it.

Now that Roastmaster has its own internal Bluetooth protocol and engine, adding support for data logging should be a trivial matter if it supports Bluetooth LE, and the manufacturer is willing to allow it.

You don't by chance have an email contact for them do you. If not, I'll find one and reach out to them.

In the main roast console this is accomplished with the two circlular buttons next to the graph: <> to increase and >< to decrease. In the analyzer, they are similar, but consist of triangles without the circle.

The console adjusts in 5 minutes increments, and the analyzer adjusts in 1 minute increments.

I will be evaluating this soon for possible inclusion in a future release of Roastmaster based on the manufacturer spec's. They appear to be better than standard thermistor probes, at first glance, but I'm getting more information from the manufacturer.

I'm sorry, I'm not going to be much help there. I've never roasted on an Artisan before. But, I can tell you that the configuration of Bean Temp, Environmental Temp, and Max Environment Temp are very common configurations in the coffee world. Lots of folks like to track all three - they can tell you different things about the state of the roast, thermal charge of the roaster, etc. If you don't mount it right away, I'd hang onto it - you might find a need in the future.

Yep. Delta curves are always graphed in the same color as the main part of the curve. Whether or not the Delta representation is shown is controlled in Preferences, as I outline earlier. Yours is set to can see the delta curve on the screenshot you posted. I've annotated it with labels (attached).

« on: June 29, 2018, 07:53:44 PM » just need one single curve to see both A) it's logged temperatures, and B) a Delta representation of the rate of rise at each moment of the primary curve

A Reading curve and its corresponding Delta representation curve are the same curve - flip sides of the same coin if you will. Roastmaster graphs the logged temperatures of the Reading curve - this is the curve itself. You can interact with this - tap it to select it, edit the nodes, etc. The Delta curve representation is not a separate curve that you define - it is simply displayed in tandem with the main Reading curve if your preferences are set to display it. You cannot interact with the Delta representation of the curve - it is locked to the "real" curve.

And, you don't need to use two curves - most roasters only roast with a Bean Mass temp curve. I show two simply because those screencasts are taken from my real roasts, and I use two. You can use however many you want, based on how many your probe hardware is capable of reading. For each of those Reading curves, you'll see the real temperatures, and a corresponding Delta representation of the rate of rise at each point in the main curve.

Just to make the distinction...the blue curve in your screenshot is a control curve. These graph as stair-steps in their own section of the Analyzer, and are meant to correspond to machine control settings, e.g. gas flow, electric current, damper and fan settings, etc. The green curve is a reading curve - these represent (at the moment) just temperature readings. Reading curves can show a Delta (Rate of Rise) curve, while Control curves cannot.

In the Roasting with Roastmaster screencast 5, I've got two Reading curves bound to probes. The green Bean Temp curve, of course, is self-explanatory. The blue curve, though, is a probe in the exhaust vent. That serves as an indicator in my profiles of how I usually work the damper at certain points of a roast. The same things could be achieved with a Control curve, similar to the blue curve in your screenshot - wherein I'd input nodes whenever I change the damper setting. Kind of two different ways in this particular example to accomplish the same thing. I like hands-off roasting, so I don't work with control curves myself.

But, to illustrate how the main curve and its corresponding Delta (Rate of Rise) curve work together, the top green curve in the video is the actual Reading curve consisting of temps - a series of nodes that are read by the probe. The very bottom green curve that's more squiggly is its corresponding Delta (Rate of Rise) curve. It simply shows a graphical and relative value of how quickly the main Reading curve is rising at each point in the roast.

The more data points the curve has, the smoother they both will be. Programatically, I cannot accurately employ any type of graphical curve-smoothing for Reading curves in cases of manual data entry, because that would be guesswork on my part as to how faithful the user is in entering nodes. So, they remain linear from node to node (notice how your green curve looks more like a dot-to-dot drawing). When you get your probes set up, you'll see them smooth out. I'd personally advise shielded (ungrounded) probes - they provide the smoothest transitions in curves. But, either style would word.

In the current version of Roastmaster, you cannot bind a probe to a control curve. That will change soon - lots of expansions are coming in the arena of profiling and data logging. Until then, though, Control curves (the stair-stepped curves) are limited to manual data entry.

Hi Chuck - thanks for the kind words. I'm glad you're learning and enjoying!!

I honestly cannot remember if I've talked much about delta curves in the more recent "Roasting with Roastmaster" videos in the screencasts library. I know I covered them in the old screencasts, but much has changed in Roastmaster since then.

The basics are this: Roastmaster shows delta curves for every reading curve being displayed in the Analyzer based on the setting in Preferences called Roast Analyzer -> Delta Curves. If that is on, you'll see a delta curve for each reading curve. If it's off, none will be displayed by default.

You can toggle delta curves off and on individually in the Analyzer by two-finger tapping to invoke the Curve list. Long tap on a curve to toggle it to the opposite state., e.g. if the preference setting is On, long-tapping a curve will turn the delta curve off for that curve, and "Delta Off" will be displayed for that curve. The inverse, of course, is true, with "Delta On" being displayed.

I think though, based on your post, that Delta Intervals may be helpful to you. You can define 3 separate delta intervals to track in the Roast Analyzer. Enter the value in seconds that you want reported, e.g. 60 for 1 minute. These three delta values are displayed at the top of the analyzer whenever a reading curve is selected. By default, they report the real-time live values of the probes, accurate to 1/2 second. If you select a node earlier in the curve, though, they report the delta at that moment based on the logged data.

The best workflow to utilize this information, is by constructing your Profiles with "Reference Curves", and using the analyzer in "Profile Targeting Mode". It's easy to see the current Delta information, then tap a close node on a Profile reference curve to see the reference delta information.

I talk about building profiles in Screencast Part 2 and expand on that more in parts 5 and 6.

Let me know if this helps you, or if you have any other questions!

« on: June 26, 2018, 02:45:37 PM »

Very glad to hear you're enjoying Roastmaster!!

Sure - this is easy to do and is accomplished via "Profiles". Profiles can contain Reference Curves consisting of curves with past data that you want to match in a future roast, alongside Curve Templates, which are templates Roastmaster will use to create new data curves that can log data in future roasts.

It sounds like all you want at the moment is a set of Curve Templates, but you can also incorporate one or more Reference Curves as a visual guide in your profiles.

Once a profile is configured, all you have to do is choose it when starting a roast, and the roast will be automatically configured, both with the Reference curves for targeting, and new Data Curves for data collection.

I walk through the process in the Roasting with Roastmaster Part 2 screencast. Essentially, you just choose "Create Profile from this Roast" to handle the creation automatically. You could optionally create a profile manually and copy and paste specific reference curves from any prior roast if you want to as well.

Let me know if you any other questions.

Sorry - Roastmaster limits a roast to 30 minutes.

Lots of folks ask about that possibility, though. I'm not so sure that I won't someday restructure things to allow long roast times like that. It would involve rethinking a few different areas, but that  concept interests me. I roast a lot of pork shoulders and butts for Tamales and BBQs - usually up to 9 hours at a time. I've often wished Roastmaster could track those myself. :)
