Windmill 38; Mini Windmill - Elenco Electronics SC3DMEG Instruction Manual

Project 46
Project 47
Modify the preceding circuit to be this one.
Blow on the fan to simulate wind. If you blow
hard enough then the color2 LED (D12)
lights. See if it is easier to light the LED than
with the previous circuit.
Assembly:
1. Place base grid supports on base grid B.
2. Place parts on grid A, and install into base
grid supports on grid B.
3. Install remaining parts on grid B.
Blow on the fan to simulate a strong wind. If
you blow hard enough then the color2 LED
(D12) will light.

Mini Windmill

This circuit improves the
air flow by removing the
base grid from behind the
fan, but may not be as
stable.
Windmill
Here the clear motor (M4) is used as a
generator, using mechanical motion to
produce electricity. Commercial windmills
have more efficient motors, better fan
blade shapes, and low friction between
their components, so they can produce
electricity even in light winds.
