I have five wildlife feeders that I keep running all winter long,these,On Time, brand feeders are good but they require 10, AA batteries and they must be changed every four to six weeks,so...
I designd and built these solar power supplies,using a Plano shot shell box,rechargeable 12volt battery,12 volt solar panel and flexible stainless steel conduit,1/2" romex connectors and black RTV rubber. This is the second generation of these and I'm sure they will give me trouble free service for years to come as the first generation did.
I built the first prototype about six years ago,it worked well so I built four more the year after that. I'm still using the original solar panels and batteries,the only thing new is the ammo box enclosures and the flexible conduit.
These two in the photos are two new ones I built for one of my neighbors.
