This is a case for my external camera timelapse controller. It holds two ESP*266 Nodemcu devices and a micro USB breakout board.

One of the ESP8266s connects to your local WiFi and then to a Bambu Lab printers MQTT service to determine when a layer change has occured. It runs code I have written. The second ESP8266 controls a Sony camera and runs a modified version of code written by Rienhard Nickels.

Full details on the device are in the YouTube video https://www.youtube.com/watch?v=qvjMZTnUbnw and its description and the code is on Github. https://github.com/ChromeBee/Bambu-timelapse-with-Sony-camera
