Wind Charger with Horn

Project Number: 58

Description: Replace the yellow LED (D5) with the horn (W1, "+" on the right). The circuit works the same way except pressing the switch makes sound from the horn. Here the horn is run by using wind power, by using the battery for storage.

Snappy: Ice storage units utilize a conventional air conditioner to make ice in hours using off-peak electricity that is often sold at lower rates. The ice is stored in a large, well-insulated tank. When there is demand for air conditioning, the refrigerant is circulated through coils in the ice. The chilled refrigerant then flows through the building's air-conditioning system inside the home or business to provide cooling.
