This Is My First Instructable........
Step 1: Gathering Parts
1.) 25mm Venetian blind louvre (8 cm) 8 pieces required - for turbine blades
2.) 6mm wooden dowel (8 cm) 8 pieces required - for blade arms
3.) 10mm Polyethylene (Cutting board or similar) [40mm diameter] 1 piece required - for turbine hub
4.) 25mm PVC electrical conduit (210mm) 1 piece required - for swinging arm
5.) Hobby Motor - Low torque (Nominal 3 Volts) 1 piece required - for generator
6.) 25mm wooden dowel (260 mm) 1 piece required - for support tower
7.) 20mm MDF (140mm sq) 1 piece required - for base
8.) Banana Socket (To suit multimeter leads) 2 pieces required
9.) 3mm Plastic sheet or stiff card (100mm x 30mm) 1 piece required - for tail fin
10.) Hookup wire (500 mm long) 2 pieces required
11.) Digital Multimeter
12.) Retaining screw to secure motor (3mm x 10mm long with lock nut)
Tools Required :
1.) screw driver
2.) solder iron
3.) drilling machine
Step 2: Blade Construction
If louvres are not available, blades may be carefully cut from margarine containers or similar.
Arms are made from wooden dowel with slits cut in one end. When blades are inserted, use glue gun or PVA glue to hold in position.
Central disk has been cut from a polyethylene cutting board using a fret saw or turned in a lathe if available.
Carefully drill radial holes at 45 degrees spacing around the hub. These need to be a snug fit with the wooden dowels
Adjust the angle of the blades by twisting the arms, thereby altering the efficiency and output of the wind turbine.
Drill a small hole in the centre of the hub to be a snug fit onto the shaft of the generator.
