Cranking this dynamo for 5 minutes provides enough power to keep a LoRa32 device running for an hour. Pretty cool!
@teslas_moustache@sunbeam.city@iffybooks nice. How does one obtain such a dynamo?
@teslas_moustache If you search for “hand crank generator,” you can find them all over. Here’s one for $41: https://aliexpress.com/item/3256804148324681.html?spm=a2g0n.productlist.0.0.7c517zAr7zArg6&browser_id=f18afa1f84344b889f9487e872f447e7
@teslas_moustache Dynamos with plastic parts tend to break if you actually use them. These ones are solid.
