As Rodney said “If I didn’t have bad luck I’d have no luck at all!”..
My mini wind generators arrived today, on the stillest day we have ever had, and the package had one less than I ordered !
From the website:
Motor diameter : 24.5mm/0.96″
Motor height : 3mm/1.18″
Motor shaft diameter : 2mm/0.079″
Motor shaft length : 13.5mm/0.53″
Blade diameter : 100mm/3.94″(after assembling)
Blade Aperture : 1.95mm/0.077″
Output voltage : DC 0.01V – 5.5V
Output current : 0.01 – 100mA
Rated speed : 100 – 6000 rev/min
So on a windy day I should get about 1 Amp at 5.5 Volts, or 1/2 Amp at 11 Volts. This will be enough to trickle charge a car battery (maybe!!).
The advantage of this type of rotor is it not matter what direction the wind is from.
Assembled with addition of a small LED attached to the wires, you can just make it out from the second picture above.
So testing? 8 foot bamboo pole, duck (gaffer) tape – that should do it …
Now some wind please !!
