Thats the message I get when I click on any of your links. If your posting pictures either jpg,gif,png etc are accepted but whatever you tried to upload the board didnt recoginise it.

Anway I read that .pdf and would be surprised if it would light an led at its full rate. An old stepper motor can be used for a small wind genny turbine and checkout this link https://www.thebackshed.com/windmill/assemblyMini1.asp

Glenn gives all the details on making it and my sticky has a heap of links to wind genny sites all ya need to do is read it.

Your knob doesn't get bigger with every post you make you know.
