I did expect there to be some water in the box as I've seen in previous experiments but this time it covered the whole bottom including the ATtiny85 microcontroller and LM2596 buck converter. Here are some pictures:
- Drain the water from the bottom by drilling small holes.
- Put the electronics on the side of the box
- Try to seal the box better
Thanks for reading my post, for now I've gotta go drill some holes!
