Last year we featured a GoPro camera remote by [Robert Stefanowicz] that was built around an ESP8266. [Robert] has been working hard on improving this project, and has just released version 2, which adds a screen and multiple buttons. These additions allow the remote to become a two-way device: you can use it to monitor the status of the GoPro, keeping an eye on things like the battery level and the current video mode.
[Robert] decided to make his own PCB to do this, so it’s also a good intro into the stinky art of PCB etching. He isn’t finished yet, though: he is looking to expand the project further by controlling more features on the camera using the third button on the remote.
