An attempt to build a small wind generator


Having problems getting over micro volts, this uses rare earth magnets from harbor frieght.
I the Bearings are skateboard bearings"Mini Logo" Brand

The coils are 110 at 22gauge wire.
The base plate for this is made to go on another project of mine witch is a light display. I want to get this all self powered.

I could go solor, but the wind blows more then the sun shines! :)

I just ordered d44-n52 for the project. I love paying more on shipping then for what I am ordering. it made each magnet $1.88per then $0.70. Today I should have the new coil setup done. Note the word "should" this has been a long birthday weekend.

 Thanks, I am finding more information that my coil placement is the other issue. So the coils bobbin might change. I am now heading to belt driven system, to increase the rpms of the magnets. Only when I get this part done, I will let out the openscad for it.

Remember a belt drive is not the best.  If you really must use gear but do realize that no matter what you use, belt, chain, or gear, the larger the ratio for more rpms results in lower torque.

Have a model number of those magnets because I suspect they aren't all that great coming from Harbor Freight.  I buy my magnets online from various sources and I mostly grab N48 to N52 (the larger the number the better) and once a N56 but it came broken and they had nothing to replace it with (was military salvage).

I am currently redesigning the coils to be added on after wound  around the plastic using a metal screw through the center.
I thank any help I can get and looking at the numbers now
