Sent the prototype roast cam back. They're going to put some cooling on it to make it work better and send it back. The mounting holes aren't problematic.

I pretty much skipped over USB sticks for file transfer so now that I need one to update the software on the prototype analyzer I have Neptune's head as about my only option.

quality time with the cat

Such a deal

I've been asked to not show the inside of this or leak the source code (which I amazingly do have access to), but here's that prototype now that it's hooked up reasonably.

New coffee delivered.

Totally normal grocery store decor.

She looked bored until I started to take a picture.

Clean impeller

There's a cat at the back door. Guess I'm not going outside. (it would disturb the cat)

Here are the graphs. B-1 has a 15.71% mass loss and the ground coffee measures 53.7 on the Agtron gourmet scale. B-2 has a slightly higher 15.86% mass loss and a slightly lighter 53.9 degree of roast. Those post-roast measurements are closer than some roasters get trying to follow the same plan but these are clearly very different roasts.

Is it nap time?

This is how the batch with the highest mass loss ended up looking. The numbers in the notes hanging off the graph are all generated directly from the underlying roasting data. Measurements in the table are mostly interpolated since it's rare to get measurements exactly on the second. They end up based on 2 measurements less than half a second on either side, so not much difference compared with taking either the previous or next measurement.

These are the cupping spoons I used today. One has a black bowl and features the Coffee Roasters Guild logo. The other is from the Coffee Championships event in Knoxville. Both spoons were gifts.

This is what I've been working on all day. #RoastingStylesExploration

What did they do to you, Miku? #AdHorrors
