In our previous article , we’ve shown you how to make a special remote trigger cable for a digital camera. It’s a solution we’re using to record our time lapses and it worked pretty well for us. However, 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. How does it work? The main part of our solution is a small development board called Adafruit Feather 32u4 BlueFruit LE. Essentially, it’s an Arduino-compatible board with Bluetooth LE module, and we’ll use it to read input on one of the pins. The input will be created by activating a pin on the Einsy RAMBo / Mini RAMBo motherboard – we can do that by including a short […]
