I absolutely love this. Well done !
If I set a camera with 1 picture every 30 minutes, how long would the battery last ? Can I set it up outside, will it take a beating under the sun and rain ?
The best way to calculate the battery life is in terms of photos. It can take a minimum of 50k photos on a single charge, so 50k photos * 30 minutes == 2.8 years. The battery self-discharge will deplete before that though, so I'd expect 12-24 months.
Note though that the SD card can only fit 20k photos, so the battery typically lasts longer than the SD card, and after that the oldest photos are overwritten!
