Becoming Myself

The head of the robot is ready for assembly. Everything is gonna be glued, because I don’t want screws (they would not look right in the size of the model) so I really hope everything will hold together….

Putting the brain together was easy enough. I am just amazed every single time by how much wood glue can handle.

When it came to the brain I had some trouble. I didn’t really run a lot of tests with the screens for the eyes, because I already coded all the other displays and thought for the eyes it would be pretty much the same. Turns out, the screens for the eyes have an SH1106 chip (instead of an SSD1306 like the others do) and the library for that is not as well written. I had a lot of trouble getting everything running and for some reason the PCA9548A also didn’t do what it was supposed to do. After a lot of panicking and buying other screens, I started over completely anew and decided there had to be SOME way to make use of the two I2C ports of the rp2040zero. After some small changes to the SH1106 library I actually managed to connect both screens to their own channels. Ready for the next stage.

He currently still looks a bit derpy, but that will be fixed in a later coding session. But he can look around and blink. So, for now, the rough head structure is done
