A MUCH needed channel. Coffee professional, engineer, and software designer. Not to mention solid video and audio quality out the gate AND solid dry humor and good presentation ability. Looking forward to your videos! Now do this to a saturated group machine because I can't stand HX 😅
Yes yes now your Reddit sheep will all bleat their disapproval of HX and relegate it with their snobbery to some dustbin. I think you and hoff are terrible monoculture shills.
I agree Lance. Love the online coffee community, for all its weird nuance and crazy price points, its still very inclusive and generous. So easy to learn from people that love what they do, thanks to all of you that pass on your knowledge, it is really appreciated. Lance and Tate you guys should team up for a video!
Yeah a saturated group machine would be awesome. Maybe turn a BBE into an end game machine with a rotary pump, wireless flow control and an extra boiler if that’s even possible by removing the included grinder.
Where can i learn more about espresso machine? if machine turn on & the pressure gauge goes up to 15bars before it slowly come down 9 bars. How can i set it not goes to 15 bars. Just want max up to 12 bars? Is it this overpressure valve adjustment?
So true, a HX is only a good deal if the output water that goes to the group head first passes through a smaller PID controlled 400ml boiler, like some Dalla Corte machines do... At the same time, a PID controlled smaller boiler assembled directly on top of the group head prevents the E61 stand-by overheating issue that even the Lelit Maras (which have a PID) have. ⬇ At the same time I was wondering, the voltage meter that sends its signal to the Arduino moves as the e61 internal valves are closing its water inlet, so I wonder if that's the wiser way to go about re-using the lever as the pump pressure controller. ⬇ Other than that, AMAZING PROJECT, my most heartfelt congratulations!! ⬇ PS: The E61 overheating issue could be fixed in machines like the Mara X, by placing a temperature sensor inside the E61 group and adding a valve that opens and closes recirculation of water from the boiler (into the group-head) according to the temperature reading. Also: we NEED more factory rotary pumps in smaller machines like the Appartamento and the Mara X.
@@DmitrijPaskevic no its worth it, I have one. I use it daily and rarely grind 20kg …more like 12g -50g a day. But if I ever have to grind a ton its nice to have that option. Fantastic grinder for consistency and serving large groups of people. You might not think its feasible for you but to some it might be.
As an engineer, I’d love to see a deep dive on why you choose certain components, certain design considerations and the software youtube seems to be lacking in engineer work for coffee machines! great video!
As a Mechanical Engineer and a coffee lover, this was just amazing! And blew me away how this is your first video. Great quality video, audio, explanation and humour. Keep it up!!
Love this, maybe mod one of the entry level machines Breville Barista Express or Gaggia Classic Pro - I know alot of people have done the GCP, however, I think your explanation and laid back approach will be appreciated a lot more
@@tatemazer I am also voting for a GCP video. It's a machine I might actually buy if there is enough community support for modding it into something desirable for less money than buying a machine that is desirable out of the box (i.e. a decent or the Meticulous Brian just showcased). I am very curious about comparing your thoughts with the videos James and Lance did.
I loved everything in this video, and I am not even drinking espresso myself. I just love it when people are passionate about their profession/hobby/whatever and are willing to share their knowledge.

I'm very happy that I found this channel! As an engineer, software developer and coffee nerd this really scratches my itch. I guess you already got many questions about this, but I would love a teardown of the Meticulous Espresso machine. This was a great video. I would like an ever deeper dive into how you built it, the hardware choices and the software.
i think you should tackle the breville barista series of machines - i notice that many people seem to have them and the older 870's are becoming very available at affordable price points to get into modding. The stock grinders are poor; but the machines are fairly capable
Wow I think we found a future Squid Espresso Machine Engineer. Concept is a $500 kickstarter espresso machine with a $1000 retail price. Still gotta launch Squid but we’re definitely interested in doing either grinders, roasters,and/or espresso machines. Great vid!! Love all these little mods. Just ordered my first e61 ECM Puristika.
As a coffee newb, I love how your personality (to me, at least) seems to fit in the middle between James and Lance. Great video. Subscribed and awaiting more content.
Having tried different semi automatic machines, but aways returned to my La Pavoni (though I really liked the La Spaciale), but this nerdy and tech video really made me want to play with more technical machines again! Thanks for the great video!
The Brewhob lives on! This video made me feel super nostalgic, incredible to see where you’ve taken the project. PID light flickering hit close to home lol
Excellent video, I was sad to see that it is the only one you published so far :p . I would love to see other machine mods and maybe a step by step explanations. Keep up the good work
Awesome, you could totally use the arduino to record the inputs of the potentiometer and parameterize different techniques and bind those to buttons/presets, less skill involved but should guarantee similar shots every pull.
That's what came to my mind too. Just automatically record the profile every time, and when the shot turned out well mark the profile for permanent storage. You could have a list of profiles with different styles, and just replay which one you fancy
Peeping that bag from B&W on your shelf - I just finished a bag of their anaerobic single origin roast, Esteban Zamora. Super good! This video is fantastic. You did a great job modifying your machine!
Absoluty fantastic !!!! Iam curently adding upgrades on mine, and i woulk to install a dual pressure gauge like you did. How do yous install the pump pressure sensor ?
I have a gaggia classic pro that heats just fine, doesn't over do it or under do it(luckily, although I am a barista so temp surfing just comes with the territory, every machine has it's quirks no matter how good in my opinion, commercial asnd domestic alike), so I'm just after adding the dimmer mod, to drop it to 9bar. Can now do full pressure profiling for the cost of a 100w dimmer, like €4.50 with delivery, ran the wire out the top and it's magnetic so absolutely zero damage and completely reverable. I'm happy and probably too caffeinated.
I don't know how difficult these mods are but they look awesome. At the risk of offending people I'm going to say that you should probably mod the Breville dual boiler. I know there's things like the slayer mod etc but I think pushing the boundaries a bit more needs to be explored and you're probably the right person to do it.
Fascinating. I'm wondering if you could somehow add a line of code that runs the pump with the group closed so it back flows out of a over pressure valve like a commercial espresso machine has to automatically bring the group temperature down automatically. It would likely need to be tapped in right before the valve on the group which would be a lot of custom work. That or it could auto cycle before loading the ground coffee. Really great work here.
Where did you attach the front pressure gauge for the brew pressure ? I would like to do the same with my apartments any instruction/links would be appreciated
Oh I love this so much! I found another guy on github who put an AC light dimmer and a digital pressure sensor into a Mara X controlled by an ESP32 and some GUI to set pressure profiles. I might want to join that party soon!
I know this video was while ago but you should be able to solve the flickering lights by telling the heater controller PWM cycle to run at the same frequency that your household power runs at IE 50 or 60hrz. Its a pretty common issue with 3d printers and the heated beds. I would assume the ardiuno based controller you have should have the ability to adjust that. Great mods!
Great video and a well-put-together Appartamento. Love the dual gauge, I think a lot of Appartamento owners will benefit just from this mod and the removal of those pesky side panels mounts.
This video is awesome! ive been modding my 10 year old Appartamento in bits over years. initially two solenoids, a switch and a pressure regulator to build my own plumb kit, and changing the physical switch for a momentary toggle to IOT enable it and turn it on automatically when i get out of bed! looking at your other videos i'm now trying to figure out if i go full on rotary pump, or upgrade the 10 year old vibe pump with a marax silent pump and a pulsor. so many decisions!! would be well up for modding with your board when available!!
I just stumbled across your channel and did not understand like 30% of what you're saying because i'm not a barista or anything hahaha But, great video! Love the image quality, the way that you bring the information and explain things, I was really surprised to see that you only have 700 subscribers. Keep it up, lots of potential in your videos :) Subscribed to your channel and hope to se more soon!
This is absolutely fantastic. Aside from the temperature inconsistencies associated with the thermal coil boiler, you've addressed essentially every beef you could possibly have with this machine. How do you shield your electronics from errant water? For example, my vacuum prevention valve will occasionally blast a little steam into the interior of my machine when it's initially heating up. I can't imagine any amount of condensation would be great for an Arduino.
Sweet build. Have you found any electronic pressure switches for espressos in the market ? Would be nice to have a digital indication and readings for more precission and controll of each brew.
Would be awesome to get more details about the controller for the gear pump. I have this idea in my head to have the chance to “drive” Manual and to have the choose of 3 mods (lever, …)
Awesome first video! I also do have an appartamento and can confirm that the tempreture sensor is the most important thing. Mine also gets very very hot!
That was super informative and articulated very well! I feel like I learned a lot about a tech segment I know little about, awesome stuff man! It’s cool getting to see someone live out the overlap of passion and skill!
Id wish i was an engineer to implement some of these upgrades too. It would be really awesome if you would give a tutorial for some sweet E61 Upgrades that everyone can manage.
Great video. Amazing mods. Gotta be courageous to open the machine and tear it apart like that! I have a QM Silvano Evo that I love, but would never have the nerve to mod! I'll try simulating your Blooming Espresso by turning on the brew pump and then turning it off for a moment before turning it back on to finish.
As the old saying goes, "Ignorance is bliss." My cheap, non-pressurized, EC680 and a Eureka Facile make the most wonderful espresso I've ever tasted. I've always refused to drink espresso brewed from a better setup than I own. My taste buds will never know the difference. 🙂 The geek in me is jealous of your setup. I found a sweet Arduino mod for the Gaggia Classic/pro, which is a bit closer to my budget. Nothing like yours. But a big step up from my EC680.
I would love a video on something like a programmable shot timer for common prosumer machines like the apartamento or similar. I just got a profitec pro 400, and now that I’ve really dialed in my coffee and grind it would be really nice to just have the program ready to go so I don’t have to bust out the scale every morning. Just a thought! Great work!
As non engineeer I wondered whether I can add e.g. a shot timer to my espressomachine that easy and now I see this :D. I think a shottimer should work.
I am watching this video while drinking an espresso made with the Flair Pro 2. It's really a beautiful machine. If it were my electric espresso machine, I wouldn't be able to make as many modifications as you. It's a little easier to do all these things with Flair.
I've had the Rocket Appartamento for about three years and it has been a good first machine. I am a "closet" engineer and would love to take on a project like this but without your skills would find this mod a little too much to manage without more complete instructions. Ever consider selling a complete kit, all parts and instructions to do this? I could handle the sourcing of the parts, but being able to purchase a control board that was fully programmed along with a full wiring diagram and instructions would be awesome. I don't know what the full mod would cost, but my other choice would be an R58 for $3K and this upgraded Appartamento with the variable speed pump is actually better in my opinion. What about starting with a more basic mod of just converting this to a PID controller? that alone would be a huge improvement and probably not that difficult.
I love that you made your own PCB, I'm in the progress of making my own machine from scratch and its always fun to look at others projects for inspiration. Do you have a part number for the connector you use on the main board.
I'm a little worried that the group lever is going to wear off in no time, check: 7:42 There's obstruction and my experience tells me it may wear off the brass. The Arduino regulator is something impressive and I will love to learn though, something new to me. I'm very concern of the exposed regulators and electronics on the right. Safety hose coming off, wet cups come into my mine. Not really a big fan of Rocket Appartamento, how can they skip placing a brew gauge on a prosumer machine and price themselves at a higher premium than most established Italian makers. The choice to remove the brew pressure gauge, is not due to any technical constraint, it is is something they have decided to do by choice. It could be easily attached to the overpressure valve. They have also cut short on the relay, full of flimsy thermostats, silly placement for the pump and solenoid. I prefer the safety valve directly planted onto the boiler, not another copper pipe. The way the heat exchanger is designed, the stability of temp isn't great. If one wants to get something similar, could simply go for the new Bezzera Aria. A 1.5L hx copper boiler with proper insulation, faster heat up and better temp range Nice and quiet rotary pump Flow control Dual gauge (pressure + boiler) Additional grouphead gauge pressure profiling. Good SSR relay Shot timer and PID Joystick wands Plumbable or switchable with internal tank. Most importantly, they are designed like Toyota and Honda, with service techs in mine. The build and choice of parts look pretty solid. They are much easier to service, electronics are shielded, meaning likely better longevity and lower cost for repairs.
Awesome build! For the Fluid-O-tech MG304, was the primary motivation to be able to change brew pressure electronically? I am looking at replacing my appartamento pump because I believe it is failing, but I was thinking about replacing it with the Lelit 4000040 silent pump, as I don't care about having the ability to adjust brew pressure on the fly. Thoughts?
Waow super happy this has been suggested to me. Excellent content & super interesting. Would be cool to see some graphs & telemetry outputs from your pulls or long term automated potentiameter actuation with repeatable pulls (Not a recommendation just an idea, I wish you the most success with this channel)
Very impressive!🧐A couple of questions, one did you design the board or did you purchase it, it looks like a repurposed mash control board? Any chance of getting a copy of your code, and can you make a video about it and it's functionality? Subscribed and looking forward to you future vids!
Purging water is just part of having an HX. It just becomes part of the process and isn’t really a big deal. Espresso by its nature is pretty extravagant with water.
Oh, and, you should probably get rid of the plexi, else you’ll melt all that nice wiring you did and those components you chose. I bet some textured brass screen would look good.
Awesome video, thanks for showing how much more awesome you can make the Appartamento. Question - did you have to move the boiler when installing the dual gauge? There is essentially no room behind the OEM gauge.
I would love to see a fully modded EC 702 Delonghi. Amazing boiler, everything else... eh... similar to a gaggia classic pro but more room for *improvements*
Thanks for making this. Can you elaborate on the electronics components? Also the dual pressure valve shoes pump and boiler pressure, is that correct? What do you use for the controller? I love the idea of the analog measure for the lever. Would the controller allow you to save profiles so you can just reply a profile that you put in manually by pulling the lever on? Is that decoupled? I have a rancilio silver and a Sanremo cube. I think for the cube that be so awesome! Ps: I’ve got a tour from Ricardo on the belweather in Berkley. Cool stuff

I am a "closet" engineer and would love to take on a project like this but without your skills would find this mod a little too much to manage without more complete instructions. Ever consider selling a complete kit, all parts and instructions to do this? I could handle the sourcing of the parts, but being able to purchase a control board that was fully programmed along with a full wiring diagram and instructions would be awesome. I don't know what the full mod would cost, but my other choice would be an R58 for $3K and this upgraded Appartamento with the variable speed pump is actually better in my opinion. What about starting with a more basic mod of just converting this to a PID controller? that alone would be a huge improvement and probably not that difficult.
I love that you made your own PCB, I'm in the progress of making my own machine from scratch and its always fun to look at others projects for inspiration. Do you have a part number for the connector you use on the main board.
GitHub page with code and details? Would be cool to have everything repeatable and open. Thanks for sharing!
I'm a little worried that the group lever is going to wear off in no time, check: 7:42
There's obstruction and my experience tells me it may wear off the brass.
The Arduino regulator is something impressive and I will love to learn though, something new to me.
I'm very concern of the exposed regulators and electronics on the right. Safety hose coming off, wet cups come into my mine.
Not really a big fan of Rocket Appartamento, how can they skip placing a brew gauge on a prosumer machine and price themselves at a higher premium than most established Italian makers. The choice to remove the brew pressure gauge, is not due to any technical constraint, it is is something they have decided to do by choice. It could be easily attached to the overpressure valve. They have also cut short on the relay, full of flimsy thermostats, silly placement for the pump and solenoid. I prefer the safety valve directly planted onto the boiler, not another copper pipe.
The way the heat exchanger is designed, the stability of temp isn't great.
If one wants to get something similar, could simply go for the new Bezzera Aria.
A 1.5L hx copper boiler with proper insulation, faster heat up and better temp range
Nice and quiet rotary pump
Flow control
Dual gauge (pressure + boiler)
Additional grouphead gauge pressure profiling.
Good SSR relay
Shot timer and PID
Joystick wands
Plumbable or switchable with internal tank.
Most importantly, they are designed like Toyota and Honda, with service techs in mine.
The build and choice of parts look pretty solid.
They are much easier to service, electronics are shielded, meaning likely better longevity and lower cost for repairs.
Wow, amazing project!!
Now I want to do it as well 😂
I’d love to see how to install these mods!
Absolutely awesome! next step is a little ML/AI so you can replicate any profile over and over!
Awesome build! For the Fluid-O-tech MG304, was the primary motivation to be able to change brew pressure electronically? I am looking at replacing my appartamento pump because I believe it is failing, but I was thinking about replacing it with the Lelit 4000040 silent pump, as I don't care about having the ability to adjust brew pressure on the fly. Thoughts?
Thank You Everybody for All that you are doing for our Planet Earth.. Peace Shalom Salam Namaste 🙏🏻😊🌈✌☮❤🕊
Waow super happy this has been suggested to me. Excellent content & super interesting. Would be cool to see some graphs & telemetry outputs from your pulls or long term automated potentiameter actuation with repeatable pulls (Not a recommendation just an idea, I wish you the most success with this channel)
Fabulous work brother.
Very impressive!🧐A couple of questions, one did you design the board or did you purchase it, it looks like a repurposed mash control board? Any chance of getting a copy of your code, and can you make a video about it and it's functionality? Subscribed and looking forward to you future vids!
Marc Rebillet has come a long way, hasn't he
The dream-appartamento 🙏🏻
This thing is g… gunna smash my Breville into 1,000 pcs
You looking for a roommate, I have a Giotto you can mess with 😂
Lol. The troubles of hair, I get it :)! Part of your charm is your great personality. Can't wait to see more from your unique channel :)!
This is incredible. I do feel like having to purge water to bring down temp in the group would be bothersome
That was the biggest reason I sold my HX machine and got a dual boiler. HX seem to waste a ton of water
Purging water is just part of having an HX. It just becomes part of the process and isn’t really a big deal. Espresso by its nature is pretty extravagant with water.
Oh, and, you should probably get rid of the plexi, else you’ll melt all that nice wiring you did and those components you chose. I bet some textured brass screen would look good.
You'd be surprised by how little heat reaches the plexiglass. Not even enough to get warm. It's held up for years 🙏🙏
me who know nothing about modding: I LIKE YOUR FUNNY WORDS MAGIC MAN
Awesome video, thanks for showing how much more awesome you can make the Appartamento.
Question - did you have to move the boiler when installing the dual gauge? There is essentially no room behind the OEM gauge.
Thanks for the kind words! Good question. The replacement gauge is tight but fortunately fits. It's basically resting against the boiler
Damn! This is great. I’d pay to know how to install the pressure gauge.
I would love to see a fully modded EC 702 Delonghi. Amazing boiler, everything else... eh... similar to a gaggia classic pro but more room for *improvements*
I dig this! Any updates? Why are there 2 SSRs? How does this system work with a sensor and a pressure stat? I really like your mod!
Thanks for all the work to make and put this video out. Any chance those circuit boards are consumer available?
Single dosing on that grinder is the actual endgame here...
Thanks for making this. Can you elaborate on the electronics components? Also the dual pressure valve shoes pump and boiler pressure, is that correct?
What do you use for the controller? I love the idea of the analog measure for the lever. Would the controller allow you to save profiles so you can just reply a profile that you put in manually by pulling the lever on? Is that decoupled?
I have a rancilio silver and a Sanremo cube. I think for the cube that be so awesome!
Ps: I’ve got a tour from Ricardo on the belweather in Berkley. Cool stuff
