Solar Garden lights

YX805 Garden lights

For these lights I just use the cheap YX805 4 pin chip with Sub C Ni-cad batteries, reclaimed from old cordless tools. I Use the 47uH inductors at 27mA. I've tested many different inductors for different brightness levels and duration. I've found the 47uH gives the most light for the time I want it to last (all night). I use 1 watt LED's, the bead style. I first started posting this design back in 2019 ( Original thingiverse link ). Now have made many changes. The tall end is so the light can be lower on the on the fence but still have the solar panel get max amount of light.
