Today I finally added all the missing components: the resistor for the backlight, the accelerometer with its i2c pull-ups, and the two red LEDs on the gun, with their matching resistors as well. I was waiting for the right sized resistors to arrive from LCSC, but they seem to be stuck at the airport for the last three weeks, so I squeezed the bigger resistors I have in those footprints instead. I also improved the idle animation a bit, adding random eye movements and improving the timing of the blinking:

Now I need to figure out how to process the data from the accelerometer to make it detect the events that will trigger different animations. And of course to draw all those different animations. It will probably take a while.
