Advice needed - Desk fan / pedestal fan as wind turbine giving 5v Answered
i've seen a few ideas online but so far no clear instructions. I want to mount a fan outside, probably on a spinning head to face the wind, then run that current through smoothing capacitors and a step down convertor to give a stable 5v output (through a usb port). The problems I anticipate are 1. keeping the electrics of the fan dry (I was thinking of mounting it in a hood / tunnel to keep the rain off) 2. the spinning head and not having cables twisting and breaking (maybe i could use the oscilating head of the fan to do this?) 3. too much power coming in and damaging the capacitors / step down convertor. Has anyone attempted a similar project and / or have any advice on this please?
