I recently found out about the ESP32 Camera boards and thought they could be useful for small, cheap (~£5) and easy to use timelapse cameras.

I created a sketch to do just that (code here in the timelapse_ble folder)

I got some pretty good results.

Update - 15/2/2020

I have now switched over to using the Timelapse2 sketch in that repository as it’s easier to use and has a preview.
