This small wind turbine developed by High Tech Handyman in 2009
The objective was to build a wind turbine that would produce 
12 to 14 volts of useful energy at very low wind speeds, while 
at the same time, learning the basics of wind turbine design.

Putting the Wind Turbine All Together

Alternator attached to plywood about 3 to 4 foot in length and 4.5 inches wide.









Side view.









Here we have a 1.5 inch PVC pipe cap and 1.5 inch PVC coupler glued together and held in place using a hose clamp and a short section of 2 inch PVC pipe split into 2 halves. The 1.5 PVC pipe at the base was shaved down a bit using a belt sander to allow for the swivel action. 

Bungee cord gets attached to the PVC pipe to keep the wind turbine from spinning round and round which would damage the electric cable.

Notice at the very top there are 3 LEDs in a circular pattern. This is just an added feature for night time monitoring. The LEDs will light up with the slightest movement of the blades. I'm finding out that the wind dies down considerable at night.









A simple cover made from Plexiglas to protect the electronics.









Side View - Notice how the cover shields the coils. One bad aspect of this coil mounting design is that the coils are not encapsulated in resin or some kind of epoxy which makes them vulnerable to the environment (Rain, ice and Snow). For now I'd rather  have the freedom to change out or experiment with the coils. In the final design I'll need to weather proof the coils. In the mean time, it will be interesting to see how the exposed coils hold up to the extreme weather conditions.










The Small Wind Turbine finally sees daylight!

Keep in mind, all my outdoor tests are being performed just 8 feet from ground level. 
Eventually I'll mount the wind turbine on my garage, about 15 to 20 feet from ground level.











Output voltage with small motor as a load, is almost 6 volts on a day with approximately 10 MPH winds. I'm estimating this wind turbine will produce 12 volts on a more windy day and once I wire the last 4 bobbins with #36 wire I expect the voltage to reach 14 to 15 volts in winds of about 15 MPH. 












That's all folks!

I'll post more as this design progresses. 

I'd like to thank all those before me who posted their home made wind turbine presentations on the Internet and on youtube.com. Without those, my project would not have been possible.

This is my contribution. I hope you enjoyed it and found it useful.
