new mill up and flying

[shawn]

This mill has taken me ages but here it is a quick description, 4 meter chainsaw blades, 9 coil 24 magnet N52 grade , adjustable mast offset , sliprings, adjustable tail length, and the tilt up tower is at 12 meters but I can wind it up to 20 meters (telescope lattice)

Looks good!

very nice ..

lots of adjustable things and the stator mounts look nice and "beefy" too....

[Wolvenar]

Looks like nice work! Do you have any performance info yet?

Shawn,
Very nice work and something to really be proud of. Envy the telescoping tower!!
Make sure you post some results of the project. 4 meters, what are you supplying with this WT?
Good luck and hope to see more in future.

No performance info yet it went up for the first time about 3 hours ago in very light wind 3/4 mph its spinning fine but minimal power made if any.
Homemade controler all done just need to finish the dumpload and wire it up, it will tell me rpm, watts, and log power into and out of my bank.

Homemade controler but not at my home, as i also live in the  land down under so its a    (fracken)    good controler 

[Wolvenar]

I'de love to know more about your controller

Candy to the eyes there Shawn, some beautiful work!

This is the debut of Robins' new controller? Looking forward to the beta testing 

That's a sharp looking brush and slip-ring Assembly, Homemade?

Thanks for the look, More Pics Please!
Cheers, Dave

I'de love to know more about your controller

That would be down to me then   
Starting from an Atmel Butterfly demo board and a couple of Dallas 1-wire chips its a controller and logger. Handles a dump load using a PWM signal to 'ease' the load on as the voltage rises and remote switches an inverter.

The measurement side handles volts, current, (hence power), temperature, dump load, inverter status, maximum power in the last hour and day, state of charge, generator RPM and reports it all on the built in LCD display, outputs it to a serial port and stores it in dataflash once a minute for later serial download (about 2 weeks worth).

Just finished an update to the website with the final schematic and PCB designs and the latest version of the software.

You can find the info here http://gilks.ath.cx/~g8ecj/New_Turbine/new_controller.html - enjoy

I've been Alpha testing the controller here for a few weeks now and been ironing out a few bugs. Its now totally run my system for a week. Some good winds today (southerly that Shawn doesn't see at his place in the hills) which tested the inverter and dump load control quite nicely The performance info is at http://gilks.ath.cx/cacti/graph_view.php?action=tree&tree_id=3 Had a few dropouts of the comms link across the paddock but I'm sure you get the idea!!

[Wolvenar]

Nice thank you Frackers, I am looking at a lot of options to do these things.

I hope to be really busy building this summer, so I'm eating up all these newer ideas that are less explored on the "other" forum 

[shawn]

Thanks Robin there is no way I could explain that and do it justice 
Dave yes homemade sliprings  around my bolt on car mmmm here is some pictures to explain

G'day Shawn,
                           Well it was well worth the wait to see this thing up and flying mate and it does look a treat too, now just remember when you take the tower down TO DO IT PROPERLY next time (hehehehehehehe)

Cheers Bryan

[Wolvenar]

That sounds like a good story of a big crash 

* Wolvenar waits for the details

Nice looking machine... and set up...... and I always get a kick out of seeing some more chainsawn blades... any pics of them closer up.?

I'm thinking everyone else makes them better than I did
