How dare you call that a "pile of garbage"!! :)) As an engineer that's one of the most romantic images I've seen in a while. That's a Picasso without canvas or oils - literally a thing of beauty! You're an artist of metal and silicon. I love it.
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!
@@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.
For the first minute I thought: Pretty neat coffee machine! Then I realized it's not the 3 parts I see, it's the whole table and beyond! Well well well.
After working in Italy for a while, I've tried all types of machines and shops in the UK to get a decent cup. I've resigned myself to the fact that I need to build my own and seeing that thick creamy coffee ooze out has inspired me to go full steam ahead with a DIY machine if you pardon the pun!
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)
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 😅
@@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.
This is an amazing project! With so much more low level firmware control, you can probably do so much more that's not available in existing machines, like custom and automated pressure profiling via pump / pressure sensor, direct group head PID temperature control and so much more! I'm hooked!
Holy crap, just stumbled on this video randomly... liked and subbed, can't wait to learn even more. Gotta love how quiet this is for being completely bare, no enclosure or sound dampening.
I was looking up flow meters for injection pump element matching and found this. Apparently precise flow is linked to expresso. So glad this was found for me.
The CNC group head is truly stunning! Quite an interesting approach to measuring the volume of water. I've used several flow meters on my espresso machine with mixed results. I've been developing a customizable Arduino program to control an espresso machine for several months. Which may or may not be of use for your custom espresso machine? If you're interested, its called "smart coffee". Ultimately, I want to get away from measuring the flow from the pump and instead measure the dispensed espresso by weight. In theory, this eliminates several variables such as the amount of water trapped in the coffee basket, OPV return lines, and system priming.etc
This is ABSOLUTELY the hardware equivalent of a software project under development. Parts are all over the place, looks more complex then it actually is.
Wow, so much effort and equipment in order to just poor some hot water over the powder from a specific plant origin to make a beverage. Feels so wasteful and unpractical on the first glance, but I can totally understand the joy and passion of the process of making it work. This project surely means a lot to you, so great job, it's fascinating. Keep on improving and have a nice time in the process
Very cool and really appreciated the component walkthrough! Seems like there could be lots of cool ways to build this into a counter or compact machine
Caffeine is the best drug! I have always admired the mechanical complexity of high end espresso machines. But I hadn't seen nothing like this. Where can I buy one, here take my money 🤑
This is so inspiring. I wonder if I can make a machine capable of flow rate + pressure profiling (think about decent) affordably, now I have to try that myself :)
All that effort and you didn't level the brew head. I like the test bed approach. Makes isolating variables easier. Is that the power supply making all that noise?
It was lovely to see this project as I'm working on something similar - except that I'm not building my own grouphead and boiler. But afetr weeing your video maybe I should add: YET. :D Ohh and tha "pile of garbage" looks so good that I could easily imagine a coffee machine with similar look! Great stuff, keep up the good work!
Nice! I wonder how the cost calculation looks (components, assembly, the eventual costs of putting it in a box to make for a more sturdy construction). Second question - how it would do in an office or even cafe or coffee shop?
I still got a gear-pump with 14 bar peak from my old oil-burner, nobody wants to buy now. Last year the membran-pump of our Espresso-Maschine failed after 10 years and we bought a substitute for 15€ never thinking about our brave old oil-burner😂
Ben this is awesome! Are you pumping a certain volume every time? I wish my espresso machine closed the loop on the mass of the extracted liquid vs the mass of the grains.
@@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.
By any chance, would this project lead to an attempt to create a frankenstein pump driven la pavoni? I have no technical skill, but since shot inconsistency has been getting tedious, I've been entertaining the idea of grouphead that has a pump taking water from the boiler, or a pump driven heat exchanger using the boiler as a heat source with a separate water reservoir. I actually have no idea what I'm talking about, but your work is amazing and inspiring.
Anyone catch the alien face in the empty glass as it sits in the brew location? One point: The brass shouldn't contact the water or the brew, brass usually has lead in it, and it will leach out. Take a look at commercial equipment, it's always stainless steel, or in very cheap ones, aluminum, but never is brass in contact with the brew or water.
Bit too much electronics for a cup of coffee😅 is enough the 2 valve for the head, the boiler one switch connected to the pump (with pressure regulator) and valves. And the coffee it will be perfect!😇
@@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!
Ben, I was wondering where you sourced your gear pump from? I was looking a while ago and couldn't find much that was food safe and not exorbitantly expensive.
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.
Why should the innards of an espresso machine be hidden? A bit of imagination on assembling these into a fixed arrangement and you have a winner product. If there is a competition for newly designed espresso machines, you should enter it in. I am thinking of either a flat wall mounted assembly, all parts and tubing exposed, - kind of like an industrial art installation piece - or a neat , compact, cubic assembly in a plexiglass enclosure resembling a distillery or chemical plant - Beaubourg-style - for a more user-friendly wider target group product.
I think amazed is an understatement of my feelings towards this creation. So so so impressed with your work.. I recognize some Pavoni bits too ;) very cool
