To get more into espresso i finally got a used gaggia classic and upgraded it with a replacement controller running the open source gaggiuino project.

Fully with loadcell scales, pressure sensor, pid temperature control and a hand soldered all in one pcb.

You can also use standard arduino style modules for most components but the pcb makes it much more compact and reliable.

In this case the modifications are fully reversible in case a future owner wants to revert it back to stock.

Works great and automates a lot of steps to be more consistent. Now i just need to practice the manual parts of making espresso ;)

Note: this is not my project, i just documented the build process on my machine. Maybe it helps someone to get an overview what goes into such a conversion and inspires more users to attempt it.

The community is already pretty big and many also adapted the project for other machines.

Is it possible to have a relative link on Lemmy for posts and comments? I've been able to link to local communities with the /c/community@lemmy.world notation, but when I look at the same post on two different instances, the ID in the URL is different, so I'm not sure how to link a relative path to a post (or to a comment).

For those uninitiated and those interested in Smith Charts, check out this video from w2aew. I recommend his channel for all things RF related.

Thought it could be fun to get a thread going on what beans we're currently using, maybe with some pertinent details on the brew variables if you feel inclined to share.

This past week I've been using Portrait Coffee's Toni, a medium-roast single-origin from Brazil, roasted in Atlanta. I've been really pleased with the taste of my pulls with a 1:2 ratio. Great chocolatey notes, which is what I typically seek.
