SLA Timelapse Controller

After getting rid of the Formlabs (blessing in disguise), I got myself a cheapo MSLA machine off amazon.

After doing that, I wanted to document it working with a timelapse. Without modifying the printer, I hacked a GoPro wireless controller to trigger on the exposure light that spills from the bottom of the printer.

I reverse-engineered the back cover of the GoPro remote, and hacked in a simple circuit to press the capture button with an arduino monitoring the light sensor.
