Mini
Mill Battery Charger
Based on a stepper motor from an old
floppy disk drive, and takes about 30 minutes to make.
The Mini Mill will generate about 1-2 watts and charge
a couple of Nicad batteries in a couple of hours.

Fisher
& Paykel Windmill
Using a F&P Smart Drive motor, this
windmill is capable of producing up to 300 watts. This
new design replaces the windmill kit I sold.

Oatley
DC Motor Windmill
Based on a 300watt 24v
DC motor, this little windmill would work well if I
could boost the output voltage.

Improving those
cheap Chinese Windmills.
The cheap import Chinese windmills
are popping up everywhere, and you can buy the blades
separately. But they are very noisy. There are two parts
to this article, firstly how I modified the blades to
give more power and make less noise, and secondly, how
a forum member, Kevin, modified the windmills to improve
tracking and reliability.

Turbine Balancing.
A very accurate way of balancing your
windmill turbine. Balancing is important to avoid tower
wobble, bearing wear and blade failures in high winds.
The method described here was contributed by a couple
of forum members, Gill and Klaus.

Furling explained.
Furling is used to protect the windmill
in high winds, but how does the furling system on small
windmills work, and some calculations to work out the
furling speed, tail lengths, etc.

The new cogless
F&P
Using a magnet hub from a late model
F&P washing machine, and a old stator, its now possible
to make a cogless 7 phase alternator. This is the future
of conversions and will replace the old 3 phase rewire
above.
