Via PrusaPrinters.org, an in-depth tutorial on how to use your smartphone camera to record your 3D prints in time-lapse mode.
… If you are not into tinkering and soldering, we’re presenting something much simpler: a Bluetooth remote trigger for your smartphone, which is controlled through G-Code commands. You can use any modern smartphone with Bluetooth LE functionality to record time-lapse videos of your prints.
The main part of the solution is a small development board called Adafruit Feather 32u4 BlueFruit LE. Essentially, it’s an Arduino-compatible board with Bluetooth LE module, and it is used to read input on one of the printer pins. The input will be created by activating a pin on the Einsy RAMBo / Mini RAMBo printer motherboard – that can be done by including a short piece of custom G-Code. The Adafruit board will emulate a Bluetooth keyboard (HID) and a keyboard button press, which is recognized as a remote trigger signal by your smartphone. Selfie sticks work the same way. The advantage of this solution is the simplicity and price. There’s nothing to solder, no resistors required… it’s almost plug-and-play.
