Wow, that was immensely fun to watch 😀 thanks for the detailed look under the hood. And your editing skills are on point! Congrats, this is quite an achievement. (Btw, I just watched this with my daughter, and she is now inspired to invent something as well 😁)
it's huge. but 18 different liquids is a great achievement. One little remark.... you mention the wire connected to the servo was straight while the valve was open. Wouldn't it be better if the valve stayed close when there isn't any power?
Busted ;) I am going to redesign the valve mechanism if there's ever a version two of MADRID. The wire is indeed not straight (aligned with the axis of the servo) in the closed position, that's an engineering mistake from my side. If the valves are closed when the machine loses power, they stay closed tight enough so that no liquid leaks, therefore it's OK for now. Maybe I'll add a spring in the next design which is able to automatically close the valve as well in case of power loss. Thanks for pointing it out!
@@BodgedButWorks it wouldn't be too hard, just make the wire a bit longer so in the closed position it goes just a fraction beyond straight, so when you would pull the wire, the servo would need to go clockwise, which you can prevent easily by just a piece of hard material. (to open it, you would rotate anti-clockwise).
Servus, hervorragende Frage! Ja, die Kraft reicht aus, um alle Schläuche hinreichend geknickt zu halten. Falls der Stromausfall grade dann käme, wenn ein Ventil offen ist (und nicht über den Not-Aus initiiert wurde, denn dann schließen sie vorher), dann bliebe es geöffnet und man müsste es kurz von Hand schließen. Aus diesem Grund gibts unter MADRID die Edelstahl-"Siffschale" 😉
@@Hi-vj4sq The web app that guests use on their phones is coded in PHP (webserver) and HTML/CSS/JS. It sends requests and orders to the webserver via AJAX. The webserver then communicates with MADRID (which runs on Python and C++) and tells it what drinks have been ordered.
This is amazing

Awww, we're so happy to hear that 😊 Thanks for the feedback, glad you both enjoyed our video and all the best for your daughter's engineering career!

@@illusionmanager Great idea, I might elongate the wires in the future 👍🏼
Beste Vorstellung ever! *gröööhhl *
Und was machen die Servos bei einem Stromausfall? Reicht die Zuhaltekraft?
Servus,

That is cool
😊 Thanks!
What programming language did you use to make the web app and how does the webapp talk to each other
