@vkess The graph code pending for v2 is really a lot better for this, having your likely use case already in mind and the ability to change colors/visibility of series on the fly.

@vkess Right now the colors on the graph are based entirely on the table column the data is in. It's an ugly hard coded thing in the graph code that loops over about a dozen colors. Enlarging the number of colors available would only require changing a couple lines of code. The harder part is behavior changes associated with having more than 2 roasts loaded. Those can all be done in a local config, but making sure things like profile translation work would be subtle.

Another takeaway from expo that I haven't posted yet: while I've never been a big fan of cold brew coffee (I prefer hot brewed iced coffee and I prefer hot brewed hot coffee even more), I have to admit that it can be pretty good if you add enough booze to it.

Cold brew isn't for drinking. It's for use as an ingredient in something else.

@NorthRiver For batch tag printing? It's one of these: https://www.amazon.com/gp/product/B06XKRN726/ref=as_at/?imprToken=R-rOvElZl2O0mlTIB5lmUw&slotNum=0&ie=UTF8&camp=1789&creative=9325&creativeASIN=B06XKRN726&linkCode=w61&tag=typica01a-20&linkId=245085e3235724e0f6d601df8f4572fb

Working lungs would be nice.

For some reason Amazon thinks that I want to buy a 4 pack of 10 bit ADC ICs. I can't think of why I would buy that.

Odds are good whatever µC I'd be plugging that into already has an ADC at about that resolution. If I needed to break out to an external chip for that I'd probably want something more like 24 bits (and then count on not using all of those bits because my circuit design skills aren't that great).

It looks like the 1.5 days of spring a couple weeks ago are all we're getting here. Now it's summer and I'm over-dressed for it.

Had a chat about how roasting classes went at Expo. There was some good feedback in from attendees (yes, I read the feedback forms) and some things that weren't captured in the forms that I noticed. While the feedback was overwhelmingly positive, there are certainly some things that can be done to make these go even better at retreat.

Loaded a new roll of paper in the batch tag printer at the roaster.

Every so often I think it might be a good idea to bridge a coffee roaster to a MIDI control surface. (Fortunately?), I don't have a machine where this wouldn't be entirely too much work.

Ethiopian coffee samples are on the way. It's been a while since I brought in a Harar so I'm hoping to find something nice from there.

I visited the city at about the same time as the coffee industry was finding out that coffees from that region would also be going through the ECX right away while they'd previously expected a more gradual phase in. This was also one of the few trips where my high school French classes were useful.

@quad Tyria

The cat has decided to add "alarm clock" to her duties. Unfortunately, she's lousy at deciding when I should wake up.

USPS has a big red banner warning that old browsers won't be supported soon and I'm just over here wondering if they ever got around to sending label PDFs with the correct MIME type. For a long time they didn't.

Just noticed that I have two scales in my roasting area, exactly the same model, and their beep sounds are 1 semitone apart. Have they always made different sounds? A third supposedly identical scale in the kitchen plays the same higher note.

@quad Oh look, it's me.

He did it for the vine.

He also died young, probably from doing this so often.

Each bag weighs approximately 60Kg (132Lb).

@vkess I'd think that whatever control scheme keeps you closer to your plan is the right way to go. Sometimes that means a gas adjustment, sometimes it doesn't.

There was a class at MICE and Expo (and retreat next) that so far has been building up a good set of data in support of the view that as long as you're hitting your development milestones and end at the same times and matching your end colors, people can't reliably distinguish between even very different machines in a blind triangle.
