Cool project. Thanks for sharing the details!

So the harvester sustains itself, keeps filling up the bucket, and periodically reports out the progress.

I guess it's a balancing game, as the filling up process is probably slow, so the target's draw needs to be low too.

Thanks, it didn’t report back progress of charging, it was connected to a sensor (light sensor in this case but could be anything really) and would transmit that back to a base station.

The main use of energy harvesting is for powering wireless sensor nodes, so this was a simple implementation of that.
