Espresso-making with the CoffeeJack v2

    I haven't actually used the CoffeeJack 2. Yet.  So this isn't a review.  Oh, I do have it in my possession, but I haven't pulled any shots, partly because I'm a regular coffee brewer, and not really an espresso maker, and I need to understand espresso a bit better before I can use this cool little device.

    Because I'm a tech writer and a flowchart and process nerd, I made myself a flowchart which I'm just dying to show off:

    Click to enlarge:

    It's a crash course in espresso-making concepts and how they apply to this machine.   It violates some best-practice rules for flowcharting, but I decided that keeping it all on one page was more important to me.

    Pretty cool, huh?  I do love a nice flowchart. I'm giving it away under a Creative Commons license (there's info about how to get an editable version at the bottom of the image). Or you can click here (you need a google/gmail account to save and edit the file, though).

    Anyway, I will eventually write a review of the CoffeeJack v2, but I have to learn how to dial in a shot first, so it'll be a while.  But the early impressions in the online groups are quite promising.

 Here's the introductory video from the Kickstarter campaign, so you can at least see how cool this thing is.   The campaign has ended, and they are in their shipping phase, and it's not yet available for sale, so unless you were a backer, you'll have to wait a bit to get one. I've linked info below.

Those gears give it an almost steampunk vibe, am I right?
