I Built an Arduino Powered Coffee Machine

[@rjbernaldo_]

Hi frens, uploaded an up to date video on how to build a Gaggiuino in 2023 👉 kzbin.info/www/bejne/oZvIhJ99ndJrmaM

[@sunriseshell]

"Like a Honda Civic from the 90's there are a ton of mods avialable to improve the machine's performance." Love the analogy! So appropriate.

[@gabrielpapasideropavan]

Would love to see this on the hands of James Hoffmann! Thats the collab we need!

[@monkeywrench1951]

I put a comment there recently asking him to have a look at it. He has several videos about the Decent DS1 … of course, a Gaggia classic pro + arduino would be 10% of the price.

[@rjbernaldo_]

I have a spare machine maybe I can ship it to him. Hmmm.

[@cchance]

Doooo ittt

[@OneIdeaTooMany]

Even better would be Lance Hedrick. He's done a few Gaggia mods before and he did build that custom Breville dual boiler machine with Breville engineers. He'd be a great person to review it.

OK. I'm now convinced I will wait for Gaggia to do this before I buy. Though you did a great job.

[@Mueller3D]

Just a note that if you're crimping your wires properly to the terminals, it's not recommended to solder them as well. Probably doesn't matter here, but for certain situations (mostly when cable movement is involved), soldering can create extra problems.

[@gabewyatt2752]

Most people go with wagos in their build

[@rsilvers129]

Mostly because the lugs are chrome plated.

[@454Casull]

@@rsilvers129 Solder can create localized stress points and doesn't provide anything that a good-quality crimp doesn't already have. If the crimps are questionable, though, solder might still be something to consider. Also, you're probably thinking of nickel plating rather than chrome.

[@deviceundertest]

not easy to find proper budget crimpers, to have proper strong crimp for open barrels, these cheap from ali and amaxon are mostly trash, and securing it with soldering is not the worst idea, you cannot make it worse this way

[@yifuwang2269]

I just get my Gaggiunio lego project up and working 2days ago, thank you for the inspiration and information.

[@davidrobertson4301]

I liked it. I saw something on how to change the spring a while ago but didn't realize how quick and easy it was. I'm going to get one and do this straight away. I also really like the music. I watched this twice for the coffee machine information and a third and fourth time just because I like to listening to the background music

[@markpirola8152]

I watched Decent reviews about 3 months ago.. it inspired me to add a pressure and temperature sensor to my humble breville em4300s. .. I was thinking of using off the shelf smart wifi devices to monitor and control… but this is elegant

[@geordieny]

Bro that music had me soooo relaxed. Very good video. Great step by step of how the process works. I'm waiting on parts to do it and it's nice to see the steps laid out in a relaxed manner.

[@Mitchvr32]

Great video, have been considering the gaggiuino for a little while now, but this video has given me the motiviation to finally do something about it.

[@rjbernaldo_]

Please keep me updated when you finally do the mod!

[@monkeywrench1951]

I’m waiting for someone to come up with a kit. How feasible is for someone to put together a kit ? This looks like it puts together most of the mods with much more control.

[@bastianpfister1492]

Thank you for this extensive video! I had just finished watching Lance Hedrick’s Gaggia Hack video thinking “all this switch flipping and seconds counting could be done so much easier with an Arduino” and here we are. You probably have solved your scales problem by now but if not: my set of scales is very susceptible to RF interference. Mobile phones, an iPad or even a smart watch can make it go crazy when they get too close.

10:04 is not a pressure sensor but a temperature sensor. Thank you for the video!

[@rjbernaldo_]

Good catch! You're correct, that's the temperature sensor that plugs into the boiler. Thank you!

Thank you so much for this fantastic video. I would also wish to intall one myself but am a bit scared to do so do to the lack of my technical skills (however I have already instsalled 9bar spring and temperature PID). Regarding the scale ... how about bluetooth scales (seems like ardunio should support bt scales???) Cheers!

[@NightHunter2223]

I’m a newbie to Gaggia’a and I’ve just bought my new one that I’m fixing up. I was just wondering if that is mod will work on a Gaggia classic?

[@chammy212]

I see that you’ve attempted both Shades PID with Dimmer and Gaggiuino. Although, Gaggiuino automates and is repeatable, is it that big of an advantage over the Shades setup given how complicated the install is?

[@johannespoell8760]

thanks for providing so much insight on your install! amazing

[@carlesmiquel]

I'm blown away!

[@spuriustadius5034]

It looks really awesome, but one safety concern: The original thermostat simply cuts-off power to the the heater using a thermally actuated switch. It's primitive but it's a nice safety feature-- no code has to "decide" to cut power to the heater. You may want to replenish the thermal paste when you screw the replacement thermal sensor in. That said, there is a thermal fuse that's clipped onto the boiler inside some tubing. Be careful not to displace that or move it away from the heater. That fuse as well as the one that's clipped into the pump are your last lines of defense for a heater that's out of control. It's a pity that Gaggia didn't simply add a chunk of metal on the other side of the boiler so we could screw in an alternative thermocouple and still leave a higher temp version of the original in there as a safety.

[@VSparxxx]

You totally can leave a higher temp thermostat in place if you wish so, the steam thermostat spot is vacant so a 165-170C cutoff thermostat should work no issues while not interfering with the mod work as well. But saying that the code has a couple primary functions that are in charge of the system health and act accordingly if any of the sensors report smth that's considered abnormal.

[@spuriustadius5034]

@@VSparxxx Thanks! I had not thought of this-- that the electronic temperature sensor at the bottom can be used for BOTH coffee and steam set-points. The thermal switch at the top can be there as a fail-safe to cut power to the heaters (with an appropriately higher temperature cutoff).

[@temyraverdana6421]

Wow, amazing job and useful, precise explanation. Thanks

[@painpeace3619]

My first question before doing such a project, what kind of knowledge should i have. Hardware and software

[@peterkang8034]

For the 5 wires going into 5v, how did you put it together? Did you solder all 5 together?

[@justinbouchard]

Hi there, wondering where you got the wiring harnesses? Like the one here at 2:17

[@rjbernaldo_]

It came with the chip. Those are actually called dupont connectors and are NOT recommended as they can give out easily. People on discord recommend soldering instead 👍

[@justinbouchard]

@@rjbernaldo_ Thank you :) Also thank you for making these videos, including your new one about this mod. I wasn't really interested in doing the scale addition but didn't think of just using an old scale I have for the parts. So I'm super glad someone else thought of it so I didn't have to lol

[@EweJinTee]

Planning to build a Gaggiuino next, now that I have modded mine with a PID. Quick question, does using different systems (Mac/Windows) affect any of the programming phase in the arduino? I have yet to do more in-depth research on these.

[@tarekmoustafa2126]

do you have extraction profiles preset in gaggiuino project? are you able to set pressure and or temp prior the extraction?

[@davethetaswegian]

Great stuff. I have a Gaggia Classic Pro with the Shades of Coffee PID. Works fine, but I have been thinking about replacing the PID controller with my own Arduino based solution. This video has given me some ideas and inspiration. Thanks.

[@dmackle3849]

@@Batwam0 Arduino are typically too weak for this, so porting the code and converting the peripheral hardware to ESP would likely be required. Shortlisting the libraries is probably an interesting and informative exercise. It would be cool but I don’t have the skills or motivation to overcome what is really the least of the problems in getting a “decent” coffee 😉

[@Thee-FM]

I wonder if using an ESP32 instead of an Arduino would bring any benefit specifically it's connectivity aspect.

[@sanjaya718]

Thank you! Very impressive video! Being less tech savvy I have a separate PID control, pressure control to 9 bar with the spring mod, an analog flow control pump mod, and an acaia scale to monitor flow and brew volume. Regardless of how one gets there, it's amazing how one can transform a very good machine into a phenomenal one in different ways suited to a persons knowledge base! I was particularly interested in the pressure monitor you added and may look into adding this if possible.

[@rjbernaldo_]

I also have a gaggia classic with the manual mods and while it's helpful to see the pressure to some extent, automated control of the pump based on the pressure reading is really what sets the Gaggiuino apart... If and when you decide to upgrade, rest assured the effort is 100% worth it and you'll be very happy 😇

[@jasontle]

Cool. Would the solution work with larger Sexton LCD (3.5")?

[@mastermachetier5594]

Curious what the cost is the gagguino is for all components and how much time do you think it took?

[@stenmartens7179]

this is for sure going to help me out when im doing the conversion in a month or so. one question i didn't find the answer to is, how did you plug the hole of the steam thermostat? at around 18:38 the piece of tape is gone but it wasn't mentioned anywhere. thanks!

[@rjbernaldo_]

I just left it open for now. It's advised for that component to be closed off so I'll try to find a solution later on.

Hey RJ great video! I wondered would this work on an old Gaggia Classic? 2006 model

[@sippy_cups]

DOPE!!!

[@LimitedWard]

Maybe I don't know enough about how espresso machines work, but the pressure chart at the end of the video seems to instantaneously jump from 1.5 to 9 bar at a random point while the shot is being pulled. Perhaps there's something off with your pressure sensor?

[@rjbernaldo_]

Hey there, you have a good eye! It's not random. It's following the configuration on 1:08 namely, 2bar 15 second pre infuse, 10 second break, jump to 9bars, hold for 5 seconds, then slowly taper off to 6bars

[@Nickporter17]

Very very cool!!

[@pepticon]

which gaggia classic should I choose for using with gaggiuino? any specific benefit between gaggia classic and newer classic pro? new gaggia classic pro cost around $650 in my country. while used romanian gaggia classic cost around $450-500. I also could imported used pre-2009 italian gaggia classic with total cost around $550-600.

[@rjbernaldo_]

I have a new video up that talks about the different versions of the gaggia classic and what I recommend to use. Just avoid the 2015 version (philips saeco) as that comes with a mushroom valve which is unusable for gaggiuino.

[@siviroonsrisuwan6793]

wonder if it can be modded to a similar machine like Ascaso Uno / Rancilio Silvia ? anyone have an information ?

[@Pauly5150]

Excellent. Way over my head for the electronics, but totally get what's happening.

[@whatthefilm3080]

Isnt it dangerous placing a T fitting on the pump to boiler pipe? Isn it possible breaking or leaking due to pressure and messing everything around?

[@rjbernaldo_]

It is recommended to use the original SAECO Gaggia Classic hose to avoid any issues.

[@guiwood]

Is is possible to connect the pressure sensor to the adaptor that comes with the shades of coffee pressure gauge (the one that connects directly to the solenoid valve)?

[@rjbernaldo_]

Good question! With the right fittings (very different from what I used in the video) it could possibly work. I would suggest joining the Discord and asking the community if any of them have tried doing that.

[@frankgarcia3310]

Could you use a larger LCD? Maybe like an 8 inch one

[@rjbernaldo_]

It is not recommended. See this comment: kzbin.info/www/bejne/ep6Upomvnr-Chac&lc=Ugzj_D-yTghKMU-Ye2h4AaABAg.9jU_v2YqVJs9jrDFUNimyl

Hi, I am 75 YO retired Telecom engineer and my hobby is electronics and IoT. Thank you for this wonderful project. Really I am fascinated by it because it is a combination sensors, actuators, monitor and control system to study and tweak around. An all in one environment to learn hardware and software also in a product of our daily use. I tried the Nano version and it works fine. But STM version goes to endless loop while compiling using VScode. Please advise where I am wrong and the points to be checked before compiling. Thank you again for this highly interesting project, with great regards.

[@daweelzondabus]

Would this work with the "old" Gaggia Classic model (e.g. built in 2006) ?

[@rjbernaldo_]

Yes I believe it's supported but it's better to check the official docs. There should be a section on both the new and the old version of the gaggia classic.

[@RepiTion830]

Great video - wasn’t even aware this was possible but have started ordering the parts already. One question - this orange tubing is difficult to source in my country and it wasn’t clear to me if you actually just reused the existing one?

[@gabewyatt2752]

Some people have I think?, I went with the clear tubing (but it seems to be unreliable for lots of people) try ali express?

[@rjbernaldo_]

You can reuse the existing one but it's going to require precise cutting and planning as you don't have a lot of length to work with. Here's a discussion I found on discord that might help discord.com/channels/890339612441063494/924775281477181470/1004914159638552577

In theory it could work if you swap out some parts and fittings, but it's definitely going to be time consuming from all the trial and error that you'll have to go through.

[@tontongasy]

Well done! Did you change for 9-bar spring in the meantime?

Still on the stock OPV spring so in theory should give me 14 bars, but the software lowers it down to whatever I set it to :)

I'm really in two minds about doing this myself. The price of parts has gone up a bit (just the basic nano will cost 50% of the machine itself), and I'm a bit worried about the longevity. I don't want to be rewiring and replacing things every couple of months due to my shonky soldering skills. Also, I'm concerned it might ruin the simplistic beauty of the machine. That being said, it does offer a lot of cool features, and I'd love a boost in steaming power...
