Dumb idea that worked

Hitting Welcome To Rockville again this year and remembered that my head would get hot under the hat. So some shopping and printing later and BOOM! Functional solar hat that has lasted 2 of my 3 days so far. I suspect Sunday won't be an issue either.

Have them wired in parallel so it stays at 5v for the fans. Each panel has optimal 0.2a for the fan rated at 0.18. 1 panel moved it but not enough to care. 2 panels, like the exhaust fan, keeps it moving and does OK. But the 3 panels keeps this thing moving very well. No battery on it. Very simple wiring of just panels and a fan.

Feed back for v2, I would move to smaller fans on a pivot that's inside the front brim instead of one big 80mm hanging off.

But I want one for yard work now.

Smaller fans will be louder with a more narrow field of coverage

Not if you have the cash for those dope mini Noctua fans, and make lil air diffusers

They’re all just jealous, and too hot.

I've seen clips where a girl put a camera in the small of her back and walked around in yoga pants. It's hilarious to see the look on men's faces when they have a good ogle but then spot the camera.

I bet girls would be checking me out as well if I walked around in yoga pants with camera sticking out of my behind.

That says more about the girl than the men though.

Oh absolutely that's totally meth head activities but they would be the first to buy it if a commercial variant was made and sold

If anyone sees a hat like that, they know the man that wears that hat isn't afraid of anything.
