I used to use Octoprint to connect to an Ender 3, which didn’t come with an internet connection. Now that I have an Ankermake M5, I don’t use it anymore.
You could connect your desktop to the 3D printer, I don’t think a Raspberry is required.
ONVIF needs a user with username and password, you will need at least a web interface to add it to the camera. What’s the problem with a web app hosted by the camera?
I’m an Android developer, I usually spot a non native app immediately and the flaws in the ui are really annoying. Web apps are even worse.
What I am not understanding is the concept of logging in another server. I created an account on feddit.it, can I use this account to login in a mastodon website? Or does it work the other way around, with me just using the feddit.it website (like I’m doing right now) to consume content from other instances? With the second option, if feddit.it goes down, my account is done, right?
While videogames are great, a hobby that dabbles with real things will stimulate you very differently. Touching stuff with your hands, the gap between what you want and what comes out of your work, the search for materials and techniques and other aspects of working with real stuff and not on predefined paths, will engage with your brain in a very different way.
Videogames and “real” hobbies (as in hobbies that use real stuff) are great together in my opinion, they complement and fuel each other.
