We got our daughter a hamster a few months ago; his name is Wally
For the past week or two, I've been messing with ways to show her what he does when he's active during the night. Right now, I have an old Samsung Galaxy phone mounted above his cage with an IP Camera app running on it.
The app takes a photo every 5 minutes, and will also record a video when enough motion is detected. All of that gets uploaded to the server here:
Definitely not perfect, but over time I'll make it more and more advanced. Thought it was interesting enough at least to share though
