DIY Carbon-Fiber Espresso Machine with LED Bling! 

Thank you Joseph!

Thank you TheGekOne! I appreciate the feedback and glad you enjoyed it!

Wow thank you very much nicest comment ever!! ❤️

Lol seriously though it is already super heavy with the copper boiler and all that so I am glad it has carbon panels vs. stainless steel or something that makes it even heavier.

It helps with aerodynamic stability, something most Italian products use nowadays

Thank you! Yes it does looks great in the kitchen! :)

Thanks Wayne! I brought the sock puppet back after I saw how much you like it 😃

You couldn’t even see it before the bottomless Porta filter

Die Vergangenheit soll ja net komplett fuer die Katz sein :) Danke Andy! Hoffe es geht euch allen gut!

😃

Thank you appreciate that!! Just got finally a real camera so hopefully the video quality will improve as well soon :)

Thank you ClearDome!!

Thanks 😃

It’s time for a Greenville visit man! :)

Oh thank you very much!! :) Much appreciated Pugbread!

Vielen Dank jpjay!!

Thank you!

Thank you!

Thank you!

Thank you Nezir!

Very much appreciate that!! I just learn as I go.

Firstly, John, receiving a comment from Decent Espresso Machines alone is an honor in my opinion. I truly appreciate your feedback! Regarding my machine, it does not have line pressure since I use a tank and only the pump provides pressure. However, I could potentially look into installing a flow control valve. I was not aware that 20% of the puck ends up in the cup😳 interesting!🤔 I hope you know that my comments were not intended to make fun of your machine. Rather, I was highlighting the fact that some people take the coffee-making process too seriously and miss out on simply enjoying a good cup of espresso or cappuccino. As an engineer, I am impressed by what you do with the Decent espresso machine. Based on my research, I understand that you use proportional valves which I assume are responsible for the noise during the brewing process? I am not entirely certain this information is accurate, but I have also read that you use machine learning to optimize the espresso-making process. The Decent espresso machine is undoubtedly an impressive piece of equipment that showcases the intersection of technology and coffee-making. Thanks John!

​@@MarkusNenning Not to worry Markus, I can certainly take friendly ribbing! The Decent crowd are definitely known as being more-than-usually geeky about coffee, so it's fair to make fun of us for that. And yeah, I agree with you that *it's*all*about*the*drink*. When people ask me, at trade shows, what's special about our machine, I always counter with "let me make you a coffee, because if you don't like it, I don't want to waste your time". Espresso needs, first and foremost, to be about pleasure for the body, for the heart. Otherwise, fuhgetaboutit! Getting some sort of flow control going on your homemade machine would be super helpful. I recommend you both look at the Bianca, and how they do it to an E61, as well as the many flow control mods for E61 that exist. One might "just fit" on your machine with minimal effort. As to what we do on the Decent, it's quite different than the traditional approach. We have a heat-on-demand water path, which gets to around 120ºC (it's pressurized), and we drop-by-drop mix that with room temperature water in a chamber behind the group, to dynamically alter the water temp going to the puck, as needed to get the puck to a specified temperature (people forget that the coffee puck is at room temperature). We need two pumps to do this, and they're vibe pumps, because we need very low latency, and very fine flow control. Rotary pumps are too high latency and move too much water for what we need. If you want to know more, here's a schematic: twitter.com/decentespresso/status/985910699267362816 And finally, let me say that I really enjoyed your film-making, your sense of humor, and just wanted to honor that effort with a contribution, if I could, to help you make better coffee. ps: your LED lit front panel is super cool. We might steal that idea from you in the future (credited!) if that's ok. -john

Wow John, an LED front-lit panel on a Decent Espresso Machine would be super cool!! I will buy a Decent Espresso Machine myself if that really happens! :) I had never thought about the latency of a water pump before, but yes it makes sense that a rotary pump, with its higher mass, would be less responsive to changes compared to a vibrational pump 🤔 And thank you for the compliment on my film-making; it's my hobby and I truly enjoy it."

Thank you Jess! Appreciate it!

Thank you!! I bought a PID specific for espresso machines, simple because I only wanted a very small temp display with only up/down temp buttons. The cheaper ones I found on Amazon all had a fairly big display with red LED segments and I didn’t like the optics of that :)

Thanks for watching!!

Thank you Danny!

I don’t know you Robb but appreciate you thinking of me as your brother 😂

I think with this one I will stick to the traditional basics :) Perhaps something fancier in the future will see.

And thank you!

All the mostly used parts cost around $400. The most expensive part was the carbon fiber panels

@@MarkusNenning thanks Mark keep up the incredible work

The main components yes. The rest is made.

Around $300

Hey Ziggy it cost me around $300 in parts from EBay and Amazon

Thanks! I ordered one used of Ebay.

No why do you think it did? 🤔 you just have to make sure everything is covered up well.

@@MarkusNenning Because I read somewhere that that particular motor, I guess the alloy, is resistant to heat. Dunno, if they are talking about the heat from the boiler just next to it, or the heat from the motor itself.

@plurplursen7172 ah ok. Well in my case the pump only runs a very short time every day (only when pulling a shot) so not even enough to even get hot at all.

@@MarkusNenning I was thinking the same. The same motor can feed a 12L 3gr Boiler. In your build it will have a long life. Real nice build btw. I am deep into my own build. 6.5L HX 1Gr boiler. I was thinking about sanding down those lines in the fitting. Now I am going to do it. Fix as many leaks before testing I am thinking

Sanding it down was the only way to get the leak to stop. You just want to make sure you take down the very minimum and very even surface cause otherwise you need a spacer/ring between the fitting/nut. And don’t over tighten that’s where the groves come from in the first place :) Good luck with your project! Hope to see a picture!

Thank you!

Thank you. Slow growth I guess :)
