Modern coffee machines just come with so much bloat.

Linux user coffee: Looks really complicated but in reality its simplest coffee ever.

This is some Gentoo coffee right here. You can tell he compiled this thing with custom flags

​@@michaelandersen7535This is some avx512 and ffast level coffee right here

​@@emersonharkin8877⚠️ God has said in the Quran: 🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) 🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran

the second i saw this i knew i want to make one of these. with some acrylic or glass to house it, maybe some base out of cast metal or wood....the thing would look insanely good!

Hat do you mean, this is the final design.

@@13squared2009I don’t think so ? The description says it’s just to test the pieces and that it’ll eventually be made into « not a pile of garbage taking up the entire bench » That doesn’t sound like it’s supposed to be a final design.

@@EmmysVerySeriousVideos I know, I was being funny.

@@13squared2009 ah shit

Any update?

Any update?

This is not true at all, italy may be the historical home of espresso but Italian coffee is notoriously poor quality and italy has a very poor specialty/craft coffee scene. Its all priced controlled, robusta rich crap espresso produced on poorly maintained equipment. (But they like it) Alternatively, the UK has one of the most well respected and established specialty/craft coffee cultures in the world. May I suggest you avoid costa/cafe nero, etc and actually find a local artisan coffee shop. There are plenty to choose from and they are not all concentrated in London. (I am part of the coffee industry in the UK)

Have a look at Gaggiuino

Dude me too I am a plumber / pipe fitter and me and my girl love coffee, it has now become my journey to make my own espresso machine. maybe we’ll have to partner up 😅

And the living room table is always full of projects 😂

@@theartofbanana My living room has a partially built pick and place machine in it, and parts all over the coffee table. Although I'm single, so I don't care.

Who needs wives when you've got projects!

I agree! Hopefully the uploader intends to make it a bare metal machine - that would be really cool and unique. Similar to that of a skeleton watch.

: )))

Right now it's just doing pressure and temperature control, but the plan is to add a flow sensor or estimator and a scale beneath the drip tray.

@@BenKatz If you're going with overengineering, I'd recommend looking into progressive cavity pumps for metering, not sure whether they're available in such small sizes though.

@@BenKatz Is a flow sensor really necessary? You could calculate the flow rate by having a load cell beneath the drip tray hooked up to the Arduino. Or am I missing something here?

@@martinvavro6883 That works steady-state (i.e. once the puck is fully saturated with water.) Although technically the mass out is different than the water mass in due to dissolved solids. What I'm currently doing (added after this video) is estimating the flow based on the pump speed/displacement and a leak mode, which was derived from measurements at a few different pressure/speed operating points. This seems to work very well, so I probably won't bother with a flow sensor.

It's happening: kzfaq.info/get/bejne/d92poq-c09Obn3U.html I'll make a less crappy video soon

Yep, it wasn't installed in this video, but there's a dedicated group head heater and temperature sensor.

Ebay - I searched for a few different brands and put in a few low-ball offers. A couple of the specific models I searched for were: micropump (gaf, gb, gc, gd, glh) fluid-o-tech (mk, mg, ms, pg, mkc, mgc, fg, dgd) Not every model of these series are good for the necessary pressures, so check the datasheets.

Coffee maker pumps along with other parts are freely available online. I think Italian Ulka pumps are the most popular ones

I made it - see the link in the video description for more details

@@BenKatz wow, very impressive. I ha eplans to build a fully steam operated unit, but the only thing holding me back is the group head/porta filter setup. I have access to everything else I need, the plan is a fully propane operated unit. Propane supplies heat for a peltier device, peltier device power control unit and sensors, propane also provides heat for steam boiler, water heater, etc.. Again, very impressive design. I like it. Nice work!
