Mech. Planetarium with 28BYJ-48 stepper

I have extended the model of @HackerJack42 with a stepper motor (28BYJ48 with ULN2003).

I got the idea to use this stepper motor from @Summons.

For this I have redrawn the base so that all components can be installed and supplied by USB-C. 

I also changed the gear ratio in the base to 1:4.

The switch is not a mechanical switch but the "TTP223B Capacitive Touch Switch".

Additionally I wrote a small arduino program (i used Visual studio Code and platformio) for an ESP8266 which controls the stepper motor and which also contains the WebUi.

The planetarium connects to a registered wlan and if it is not available it automatically creates an access point with the same IP address after 12 seconds. On the WebUi 5 speeds can be selected or the stepper motor can be stopped.

WLAN, AP and IP address settings must be adjusted in the *.ino file.

I printed all parts with my Sidewinder X1 and for some parts a support is needed.

You also need some M3 screws and the following parts:
