Solar waver powered by homemade rechargeable
This video is for Granddad. He has successfully replicated one of my homemade batteries that I built back in 2012. OUbrads also replicate this rechargeable in 2013 and he did it using a small pill bottle like I show in this video. My original cell is still working after 8 years.
Here is OUbrads replication from 2013: https://www.youtube.com/watch?v=I0nMzThmI5I&t=180s
