@Waachia We chose to build a micro wind turbine like the half size of yours and we have 1 question formulation for this project (we are 3 pupils doing this in highschool in Sweden). The first is to look at 2-3 different forms of the blades and see which one is the best. Do u have other suggestions ?
The shimano hub is cheap, but it's not nearly as efficient as the Schmidt SON28 - which is in the 80-90% range versus aroun60% for the shimano (if I recall correctly) The SON28 would also exert less drag on the the blades. Just FYI in case you planned to improve the performance.
please keep up the work and post it with all the info because this is just what i was thinking of doing but i don't have the cash to experiment or the knowledge of electrics
It was £30 for the Dynamo and £5 for the Tube, then a further £5 for the nuts, bolts and bridge rectifier, all that needs doing now is a slip ring to be made up in order to allow the wind tubine, when mounted correctly, to rotate into the direction of the wind and transfer the AC from the Dynamo to the circuitry below.
If you look around you can pick up the Dynamo for a lot less than £30, I put a max bid of £30 and some cheeky git pushed my bid up and then retracted when they over bid me.
Hi, are you still available? Need to ask some quesitons

Drill out the spoke holes and fit two 4 - 6mm thick aluminium disks about 150 - 180mm in diameter - each end of the hub, to mount your blades on.

Did you go any further with this or was it just a proof of concept?

@bumpf1 It was just a proof of concept for now.

Although the SON28 about $250 USD.
Awesome project.

Nice job i must say, but then , shaping a cylindrical plastic pipe into an airfoil..? how
convenient was that?...

How cheap was that? Would the British weather trash it do you think? Really cool job guys !
