Prusa GPIO Hackerboard Timelapse Cover | Smartphone

This is a minimalistic cover to house a bluetooth remote trigger and a Solid State Relay (SSR) to create beautiful timelapses with your smartphone.

Fuction: 

The GIPO Board sends a signal to the relay which then simulates the button press on the bluetooth remote trigger.

What do you need?

• Bluetooth Remote Trigger like this or this this.
