The more I think about the more I feel that this is the wrong solution to the problem. Disclaimer: I'm doing a small open source espresso controller project, check it out if you're interested, but it's not ready for prime time yet: https://github.com/variegated-coffee.

My thinking is that this machine appeals mostly to people who already has an espresso machine. It's not particularly technologically advanced. It's a single boiler, an E61 group and a vibratory pump. If you're buying this machine, you're probably replacing a machine at a similar technology level, and that's not really a sustainable choice.

A well maintained espresso machine has a lifespan in the range of decades. Many recent innovations in espresso machines is mostly controllers, sensors and actuators. Also better pumps. These are all things that can easily be retrofitted to an older espresso machine.

There has been innovation in other areas not easily retrofittable (saturated groups, dual boilers instead of heat-exchangers, to name a few), but this machine doesn't really feature any of those.

I strongly believe that in this particular demographic, it's a much better (more sustainable, cheaper and all around more fun) idea to retrofit new and advanced parts to the espresso machine they presumably already have, than to buy a whole new machine. We don't need old espresso machines on landfills.

On the off chance that a prospective buyer doesn't already have a similar espresso machine, this isn't too bad of a choice, and the price is decent, but on the other hand, there are a lot of used machines on the market that are looking for a new owner and can be upgraded.

You can get a similar machine (Quick Mill Carola) for the same price, assembled. To scratch the hacker itch, you can get a much cheaper machine (Gaggia Classic Pro, Rancillio Silvia) and install a PID (a computer to control most of the brewing parameters).

I understand the appeal to "hackers", but if you just want coffee, there are more, proven reliable, less expensive, options.

A neat project for sure but as it stands this has major safety issues. The control logic is able to lock up and keep the boilers heating element in an forever "on" state till something snaps. I couldn't find a mention of safety in the manual nor see any mechanical safety failsafes in case of overheating.

It is a better-than-1200E machine at the end of the day when you look at the components and overall build.

It has PID temperature control (typical) but _also_ pressure control. You could build a Gaggiuino for less money and the same effort, but you'd be left with a far lower quality piece of hardware as the Gaggia hardware has a shitty boiler, plumbing, group, and casing.

I'm not a huge fan of vibropumps either, but they're common for pressure profiling machines (up to $3-4K) because they're easier to control and compact. Moving to a rotary pump would cost ~$300 more at the component level, so while I'd a reasonable upgrade it would hurt the overall economics of the product to make that standard.

I still think it's expensive -- I personally would try to hit the market with a $999 kit cost if at all possible. The market for big spender espresso geeks without a machine is indeed small.

I have a Consumer Reports subscription and I’ve seen countless videos on YouTube about espresso machines, but after all these years I still don’t own one.

I’m not an enthusiast. I just want a high quality espresso machine that makes consistently good espresso shots. I’m never going to be someone who wants to spend 15-30 minutes on creating a shot of espresso.

I’m bewildered that a machine that makes hot water push at high pressure through a puck of grounds costs more than a high-end computer.

What do people buy who don’t decant the smell of their own farts who just want an espresso machine?

What’s the ATH-M50 or the IBM Model M of espresso machines?

I am the “self-upgrade my hardware” type. If there’s one piece of advice I didn’t listen to it’s “just buy the nicer machine” for espresso. While it’s fun that I got to upgrade the parts and make it better. It also cost me just as much money. The tinker aspect only involves a few simple upgrades on my Gaggia Classic Pro.

But what I didn’t realize is that espresso machines, much like other consumer hobbies was already a fairly expensive area to get invested. You get the machine but then you need a grinder, a milk steaming container, the beans, the tamper, the portafilter mesh screen, a deeper basket, bottomless portafilter, the “better” steamer tip for the wand... On and on you can invest money in this consumer hobby, middle man cornered market. Do you have the special tool to loosen your grounds if you didn’t tamp correctly? You’ll use it once or twice before just dumping out the grounds instead.

I have definitely reached my financial limit on the coffee experience. And most of the extra crap I bought bundled. At some point if I continue investing, I would not be saving money from buying a $3 cup of coffee from the cafe and the awkward barista waiting for me to tap the tip screen.

When I sell I’ll probably just buy a moka pot and milk steamer of some sort instead.

If you are passionate about Espresso, I really suggest to try Kamira (https://www.espressokamira.com/). It's very easy to make and maintain and you can have espresso at home like the one in the bar.

I am Italian, so coffee is almost a religion for us

I’m not a really avid espresso person but IMO any decent espresso machine could do the job, the real deal is the coffee grinder. Invest in the highly precision grinder could up scale your espresso shots without an expressive coffee machine.

I’m kind of late to the conversation, but one requirement most home users overlook is using lead free parts.

The brass in most high end heads slowly leaches lead into the boiler water. Arguably, this doesn’t matter at a coffee shop, since the boiler turns over the water in a few hours. At home, it takes a month or so.

Anyway, I settled on a Flair Classic lever machine (one moving part, all stainless steel and silicone gasket on the water contact path), and previously, a PID kettle.

It turns out that water boils at espresso temperature at ~ 2000 ft, so when the PID kettle died, I replaced it with an antique enameled cast iron kettle (my induction range heats it up ridiculously fast).

I boil the stainless espresso machine head in the kettle with the espresso water, which achieves the same thing as continuously circulating hot boiler water through it in commercial espresso machines.

I put the money I saved on the machine into a small commercial-grade burr grinder (like for the decaf beans at a coffee shop).

I haven’t noticed any consistency issues vs. a $3500 machine at work. That thing can crank out four espressos in parallel all day long, but I don’t need that at home.

Sadly the website was knocked out by HN, I guess.

Anyway, I really like my Flair. It is fun to press the thing manually. And it is nice to have espresso still during a power outage (as long as I can get ground beans and fire).

I think this is a different definition of “do it yourself” though, hahaha.

Love it. There’s a surprising amount of hackability in espresso machines — reminds me a lot of bicycles as an approachably fun tinkering project.
Arch-TK
Why E61 though? Strictly the most annoying type of group especially for home use.

Got hit with a popup to signup to something before I could even read their "splash" message, jesus christ

Looks cool but for me a manual machine like a Flair is ideal. I don’t have to spend a lot of time or money and I get consistently good espresso.
jcgrillo
Calling this thing "DIY" and shipping a box of prefab components is a little rich... I was expecting to see blueprints for a lever machine or similar not something using a bunch of production components kludged together.

That said, not everyone is looking for a machining project, but this is basically "some assembly required" not really my flavor of "DIY".

pipeline_peak
A 1,200 € espresso machine you have to put together is………out there.

Having an open firmware appliance is cool. But latching that technology onto an espresso machine, something that’s existed for hundreds of years is ridiculous.

This device is for tech yuppies. Guys in the Bay Area who can boast about how their espresso was made open source.

hn_throwaway_99
This is very cool - website is down for me now but looking at their Instagram post looks like an E61 group head, and espresso-only functionality (no steaming) which simplifies thing a ton. Looks like this would pair really well with a Nanofoamer for people who like milk drinks. I'm definitely tempted!
mysteria
I don't see a license in the Github repo, so currently the code for this machine is only source available and not open source.

couldn't find official confirmation anywhere, but that looks like an arduino MKR WiFi 1010, which means it should have wifi for integration with home assistant or something. I realize that the overall process is probably too manual to fully automate, but you could at least turn it on and get the water heating in the morning, I imagine.

Although now that I look a little more, according to the quick start guide, wifi isn't yet enabled in the software, although I imagine that means they have plans to. Plus of course, with open source software, I guess it wouldn't be too hard to do yourself.

I like this thing! Would love to see James Hoffman review it

stiray
Would love to play with it but for this price they can keep it.

Dont understand me wrong, love the idea, but selling it for this price is just crazy.

Consumers should be more aware that if they can afford something, this doesnt mean it is worth buying it.

9 bars of DIY pressure scares me.

I love espresso. But I don't think I'd be interested in a DIY option.

I tend to use Nespresso, especially now that the cups are simply available in the shop (and cheap aftermarket options), it's pretty perfect.

I know the manual process is more environmentally friendly but when I wake up in the morning I have no headspace for fussing with coffee grinds. I just need good coffee right away. And I don't even own a car or anything nor have kids so my footprint is pretty low.

wantstothink
This is the precipice of fourth-wave coffee. Bringing your desktop computer to a cafe, hooking it up, and remotely brewing a cortado somewhere, in a different time zone.
its_down_again
Honestly, it looks really great. Definitely more polished than what I was expecting from open-source/hacker setup.

I've been dailying a Breville dual boiler since 2019, and I've tried a few other machines at coworking spaces and friends' places over the years. For me, as long as I can hit 9 bars with a decent puck extraction, the machine itself doesn’t make a huge difference in flavor. The challenge is finding the right beans, and the fine-tuning through the grinder and puck prep.

It's not that my machine struggles to push water through consistently, it's that I struggle to nail the grind size, achieve even particle distribution, and tamp evenly. Mornings especially—I just don’t have steady hands right after waking up. Funny enough, my best shots are usually in the afternoon. Sadly I try to avoid drinking coffee past noon, so it’s often for someone else, and I just take a tax with a tasting spoon.

The way I see it, upgrading the machine helps with drinks per hour throughput, not single shot quality. I think that's also why the at-home coffee community is more into things like the niche grinder and blind shaker.

The build timelapse is fun given that the light/shadow gives a strong additional sense of assembly duration.
MostlyStable
looks like it got hugged to death, and the archive.org snapshots are from when it was "under construction"
pier25
Is this a single boiler or hx design?

Had a gaggia classic for a couple of years and I would never go back to single boiler.

system2
I was at the China Trade Expo at the Los Angeles Convention Center 2 days ago. A brand called Java sold automated espresso machines (huge, nearly commercial stuff) for $140. It made a great espresso as well. DIY sounds fun but I'd rather spend $140 and call it a day.
CAPSLOCKSSTUCK
I recently bought a super automatic machine for only $350, and it doesn't include a steam wand (big plus for someone who never makes milk-based drinks). This seems like a fun project but simple off-the-shelf ones are really coming down in price.
benrutter
This is very cool!

Sidetrack: the website mentions "driving espresso innovation forwards". Is this a thing? I love coffee but mostly just use a french press or a moka pot (which are more "great old school tech" than "innovation")

It's interesting that having a serial number tag is listed as a key feature.
ragebol
Came accross this cool idea. Downside is I don't like coffee, much less espresso

> Build your own espresso machine and configure it with our open source

Why even use any software, why can't it be fully analog manual control?

ReptileMan
Off topic - has anyone found cheaper sets of sifts than the kruve. The grind us way more important than the machine.
avtolik
This looks cool and hackable. I wonder though how much control over the pressure you can get with a vibratory pump.

This is needed now that Gagguino in a petty bit of drama is no longer offering source code, and locking into hardware suppliers.

Gaggiuino Gen 3 is free to use and will offer free software updates, but the source code is no longer available.

This decision was made to maintain high standards for the hardware required for the project and prevent individuals from fracturing the community with subpar, non-standard components and processes that were untenable for Gaggiuino’s community-driven support to accommodate.

Sincerely, *The GAGGIUINO Team
