[Ben Katz] is in the process of building a compact, closed-loop espresso machine, and really seems to be pulling it off in the first shot. Though it may not be the final product, we’re in awe of the beautiful guts and would love to taste-test the early results.
This machine will hit a sweet spot between lever-type espresso machines that are like driving a manual without power steering, and those fully automated machines that squeeze all the fun out of playing barista but are easier on the joints.
Here’s how it works so far: a motor drives an electric gear pump that pumps the water through a heater. It’s a closed-loop system, so there’s a 3-way valve after the heater that keeps sending the water back until it’s deemed hot enough. Once that happens, the valve switches functions and begins to pump water through the group head and on to the coffee grounds.
[Ben] designed and milled a beautiful group head that’s designed to fit a La Pavoni portafilter and some other parts he already had on hand. Grab a coffee and watch it pull the first shot after the break, then stick around to see the milling and the drilling.
Ready to kick that Keurig to the curb and get an espresso machine? Don’t just throw it out or take it to a field and smash it with a baseball bat — turn that thing into an automatic drip for a small houseplant.
Thanks for the tip, [tokol0sh].
Very cool, but will it fit on my kitchen counter?
And did anyone notice the skull in the glass before it filled up?
Not on, but IN the kitchen counter!
Ha. Yea, rewatched the video and there it is. Devilspresso
What Cnc is that?
Looks like a Pocket NC V2.
This ?

Talking about that 5 axis machine and even putting that up on the title would be a better take. I am sure that would have some of here talkin’
There’s a whole post on this:

It took all of 1 minute to find this on the blog.
I love old cars without power steering… It’s like walking barefoot. You can clearly feel whats under your tires…
Unless it’s something like a 1967 Chevrolet Biscayne with an inline 6 & power assisted nothing. That’s more like driving a parade float.
Was it only the V8 that had the recall on the motor mounts?
Very nice project. I’ve been thinking about something similar, I just don’t have the necessary equipment. All espresso machines with pressure profiling cost over € 3k. For example, Decent or new VBM …
I don’t mind investing time and still have fun.
This is what the morning is missing. Time for espresso.
Okay, let’s start a totally predictable discussion about food safety of brass…
OMG BRAS NOT FOOD SAEF
That is not brass, its an Aluminum Alloy.
So, we’d iz it about bras thas not save 2 ete?
(Yummy! )
What model of heater do you use ? Thermoblock i think. On the group head do you have a cartridge heater ? Is there a link for this complete projet I am interested. Thanks.
