Building a smart espresso machine with Gaggiuino

This build log shows how the Gaggiuino project gives an old Gaggia Classic modern features to step up your espresso experience.
It is not a step by step guide as it depends on the components and machine used but should give an overview about how this modification can be done.

This project is more than exciting now that they finally rolled out the E24 model with the uncoated brass boiler that does not include any lead whatsoever. Looking forward SO much to it! Thanks for your insightful guide, I'll definitely modify mine aswell

[@darshilshah6290]

Hey sir can we do all this customization in E24 i am looking forward to buying it from peakcoffee V4 expedited kit .

[@user-no3eb3jf4s]

Lead free brass still has a few tenths of a percent of lead in it. Likely going to do you no harm, but just wanted to let you know.

[@phraktl]

​@user-no3eb3jf4s This is true. The CW510L brass used in the boiler contains 0.2% lead.

[@lib747]

Big thanks for putting this together. I've ordered the GCP, and will be getting the PCB3, hopefully the August, 1st run. I'm sure, I'll be rewatching this video many times, once I have all the parts, and start working on the mods.

[@v0idgrim]

Just got My PCB for the same GB :) watching because of that. I'm also thinking about mounting the screen in the front. Actually might redesign the nexion to work with their bigger screens so I can get some more detail and resolution :)

[@lib747]

@@v0idgrimI really like the look of a front mounted screen, but I'm worried that the group head heat might be too high.

[@TimothyScotts1]

Thanks for putting this up! The Gaggiuino is a project I cant wait to get started :) I ordered pretty much all the mods you can get for it, but this is the first time I've seen the hardware scales in place. They look as though they work really damn well!

[@BKHD605]

That's insane, been thinking about making something like this for weeks after seeing a video on the zpm nocturn. This should be a good watch.

[@romankrmela6679]

Amazing piece of work. I looking forward for updates of this project.

[@rick5078]

If you are going to do this build with a gaggia classic, make sure to get the 1991 classic version or the new classic pro version, the more recent classic version has different parts.

[@phillipterrance4171]

Amazing! Your video came just in time, I was planning to start my GC PCB v3 build this week :-) thanks for the time you put into this, it's very informative.

[@Joseph_Coutts]

Thanks for this video. I just got V3.1 kit from PeakCC but have be struggling to visualise the schematics and connections. This does a great job with that

[@justin2956]

How did your install go with the 3.1? There aren’t any videos or info out there about the 3.1 install and end results. I’m getting ready to do this mod myself.

[@Joseph_Coutts]

@justin2956 my recommendation is do the custom cables. Rather than trying to work out the stock integration

[@dazza9360]

Brilliant vid on the Gaggiuino build. Thank you so much.

[@thedude4795]

Haha, didn't know we had another common interest! I also own a gaggia classic. No pid.

[@xrhesusx7301]

Do you have an estimate how much the built cost you?

[@UnKn0wn_Id3n717Y]

Nice Project. Thx for the video. I have planed with a mate to build a full coffeemaschine. Not only expresso. Grüße aus dem Schwabendland :)

[@josefzachariassen]

Thanks for this video! I have the same old machine and am awaiting the last parts for the Gaggiuino mod. Will definitely use this video as help for the installation :)

[@davidev7]

hi, congratulations for the work. one question...did you assemble the pcb yourself or did you have the person who printed it do it?

[@cjfromgrovestreetyee]

Gutes Video 😊

[@timgerber5563]

Geiles Projekt und mega cool, dass du es gefilmt hast! Was würdest du sagen wie viel Zeit hast du insgesamt (filmen ausgenommen) investiert? Grüße gehn raus!

[@DoomedAl]

@Gigawipf Nice work! Will you upgrade to or build the Gen 3 Gaggiuino?

[@ThaLiquidEdit]

Thanks for the video! Great project!!

[@thedude4795]

I hold the steam wand at half the radius in the jug to facilitate whirling. But not bad for a start at all! How was the coffee?

[@adfadf9785]

Is there a way to a more simple mod where the heating element turns on when you push the brew button to get higher and more stable brew temp?

[@nicholashorswill4052]

A PID kit is about $100 and allows precise temp control. You still need to open the machine but it's pretty easy.

[@CH-yp5by]

Its a really good video I have 2006 classic with the PID and pressure Gauge with dimmer mod and am thinking of going this mod. I was wondering why did you not do an SSR for the steam? Is this because you did the Ardiuno not the STM32 upgrade Gaggiuino mod.

[@Gigawipf]

There is no extra part required for anything steam related. Steam mode is just increasing the boiler target temperature. The heaters are already controlled by an ssr.

[@CH-yp5by]

I already have a Mr Shades PID kit with set box top and dimmer mod etc. That came with two SSrs's for some reason.

[@Conservator.]

12:18 Isolating the boiler might help (if there’s enough room to do so).

[@Gigawipf]

yes that would be possible but also make maintenance harder if you want to get to the controller

[@alexp2306]

How did you wired the water pump? I am building the lego version and I am not sure how to go witth the wires from the dimmer to the water pump and what. Thank you in advance

[@CH-yp5by]

I'm surprised you did not upgrade the shower plate with a brass one

[@Gigawipf]

Yeah i should have. I thought about it but it was more expensive and assumed the original one would be fine.

[@michor10]

Thank you so much!

[@dr.emmettbrown8466]

Great project! Is the source code open? If so, where can I download it? I'm doing a similar project, but for Rancilio Silvia and on STM32F413VGT6

[@flippy9133]

very cool

[@ZaidJilani]

may ask why did you choose PCB over lego build?

[@Gigawipf]

Because it is much smaller and will be more reliable if there are less wires between the modules. Overall a cleaner setup

[@michalthestink]

Thx for the vid. Is this the v2 version? It says that the project wont work on this

[@Gigawipf]

the PCB is based on the v3.

[@michalthestink]

@@Gigawipf In the gaggiuino docs I see that there are five 220v models - the OG classic, v2, pro, pro eco, evo pro which one is the v3 that you've mentioned? Also the docs specified that the v2 which looks just like yours is not supported, what do i miss?:/ Sorry for the stupid questions, I just purchased the v2 especially for the project and ran into the compatibility table and unfortunately mine in the unsupported list:(

[@Gigawipf]

@@michalthestink Thats what you mean. It should be the original classic model. The v2 seems to have a different boiler style and no active 3 way valve.

[@michalthestink]

@@Gigawipf but yours looks like the v2, doesn't it?

[@Gigawipf]

@@michalthestink No it is the original version. The V2 is a light version of this one but looks similar.

[@johnspanos3862]

Can this be done with the new gaggia classic 2023 evo pro? Thanks!

[@rohit275]

Not OP, but yes it can. I'm planning to do that as soon as my parts come in

[@joshgoodman]

Can you post a link to the bread board you use

[@taylorwarwas4425]

Where do you purchase the PCB? kinda a silly question

[@jakubpesko868]

Would you be willing to share a profile you use for an espresso. It is kind of tricky to set the right settings. It's not as straightforward as I thought it will be.

[@Gigawipf]

That would depend on the rest of your setup. Better check out the gaggiuino community and what they recommend. I usually use something close to default settings, 2bar preinfusion, 9 bar start and a duration of hopefully about 20-30s but depends on what you want to brew and how you grind and prepare it.

[@juras0725]

Thanks for the video. What portafilter you use?

[@Gigawipf]

A nameless one you will find when searching on ebay for gaggia compatible 58mm replacements

[@juras0725]

@@Gigawipf Thanks! Looks nice 👍🏻

[@philipecsun]

Can Auto Steam be programmed, for auto hands off milk steam?

[@Gigawipf]

No it is still a manual system but automatically keeps the pressure.

[@v0idgrim]

Hi, Is there a reason why you did not use PTFE tube for the pressure valve?

[@Gigawipf]

Its just what i bought and a clear tube makes it easier to see if bubbles remain. Should still be food safe of course.

[@thomaslerner4278]

Kurze Frage : wie gut sind die sog. Prediktiv skales ?

[@Gigawipf]

Nicht getestet da ich loadcells verbaut habe.

[@BobberWCC]

Awesome

[@lamng.156]

Hi sir . I'm having a project related with this video . Could you get me some communication to you ? Please

[@myname-mz3lo]

i asked about doing this to my delonghi ecp3420 in the community and they straight up dissed me and just called the delonghi trash instead of helping me make it not trash . extremely toxic and elitist community . too bad because the project could have been open truely open source if it wasnt for the creators being so weird about addapting this to other brands of cheap machines. i got help outsode the community and it worked great . great project but terrible entitled and judgemental people as is often the case with open source

[@erick8862]

The name of the project is Gaggiuino, not Delongino

[@user-hk8np4dw4o]

Your complaint is foolish. Someone made a mod for a specific product and you are mad they wouldn’t specifically design an entirely new mod for your cheaper machine? Not to mention the machine you are using uses inferior internal parts. Do you go into a grocery store and get mad because they don’t sell lumber too?

[@mohsguy]

But delonghi is truly just trash components
