Hey All! First Post! Okay, so I'm not officially 501st yet (pending photo approval atm) but I've spent A LOT of time on and inside my bucket. I'm SUPER happy with the fan situation. I've placed 2 5v brushless cooling fans up in the top pointed down towards the face. Ensuring my breath blew down and out instead of up and around was very important to me and my visor. Also (and mainly) for some reason, my face is SUPER close to the face shield so I couldn't shove anything anywhere near my mouth. Each fan is powered individually by it's own ANKER lipstick USB power pack that I've sewn into little pouches with little velcro straps to attach to the back of my hard hat thingy. The USB cables I salvaged from a couple of those micro drones that bit the dust so I soldered the fans directly into the boards and closed the back up with hot glue. As you can see I've left a good amount of cable coiled up to make replacement super simple.
