little rechargeable battery in there! https://cdn.masto.host/socialwakest/media_attachments/files/111/178/837/234/793/191/original/5e7ac32888afc108.jpg
the batteries say "ni-cd 2/3aaa 100mah 1.2v xinjiang xingtai new power co.,ltd" but there are no google results for "xinjiang xingtai new power" which is sorta impressive for a battery manufacturer to have no results
harvested components! look at all these adorable rechargeable batteries that have definitely only been used for one cycle on another note: these are not solar panels like I originally thought. they are light sensors (I guess the same idea but really shitty for collecting power) https://cdn.masto.host/socialwakest/media_attachments/files/111/191/457/473/771/625/original/69a24656c7b87ef8.jpg https://cdn.masto.host/socialwakest/media_attachments/files/111/191/457/769/037/276/original/73c755130fc76086.jpg
