Prototype 55x60 mm solar cell rotating base I design the base in the hollow inside however it was not added to this particular version but you will see it in the images or versions of it nothing new nothing crazy just playing around. However I'm looking to scale and I see potential just you know be careful. They can actually pick up a lot of voltage I will be having a buck boost converter regulate that if needed however we'll see. I'll give you some kind of comparison like each panel or each set of panels can power so much and it's getting off so much you know of each metric so if you're interested I guess stay posted if not thanks for checking out... I forgot to mention a lot of this is glued together just to make sure I had the proportions right and you can kind of see what the internal mechanism that will turn it looks like it's on a screw sticking vertically upwards near the forward facing panel
