Mini-Mill
Nicad battery charger. I fitted a couple of white LEDs across
the battery pack to act as a night light. The PVC blades
work very well. You can see the full details here.
A early attempt at dual stators. The plastic Smartdrive hub has too much flex and I had problems with it rubbing against the stators

Test assembly of 5 blade design. Blades cut from 300mm
dia PVC pipe.
The 5 blade design convinced me to go for 3 blades.
Mill was to slow.
Storm blew over this windmill. Ground was soft after
days of rain, but my fault really, the guy wire anchors
were completely inadequate.
Blades survived fall and were reused
Early windmill build from a modified
ceiling fan.
Another stator ready for testing. This one is de-cogged.
Small induction motor conversion driving a 20watt bulb.
Induction
Motor conversion. Output voltage was 8 volts at 500rpm,
So I'll use a small transformer to double the voltage.
Output current was 6 amps shorted, not bad for a 1/20th
hp motor conversion. Click Here for the full story.
