2017 eclipse Raspberry Pi pinhole box

I recorded the 2017 eclipse from where I was in Boston using a pinhole box with a Raspberry Pi 3 and 8MP camera in the box.

Pinhole at top left, display screen at bottom left, rpi, camera, and battery.

Here's the resulting video, 10 seconds per frame displayed at 30 frames per second for a 300x speedup.

It never quite focused right. If I were to try this again (in 7 years, with a rpi version 9 and whatever upgraded camera comes with it then) I'd try harder to seal off the light leaks from the box. I wasn't on my usual network and couldn't log into the rpi to get images as it went so I had to open the box now and then to reposition and track the sun.
